Page 23: Questions Many People Ask About Safety Belts
With safety belts, you slow down as the vehicle does. You get more time to stop. You stop over more distance, and your strongest bones take the forces. That’s why safety belts make such good sense. Here Are Questions Many People Ask About Safety Belts Won’t I be trapped in the vehicle after an accident safety belt?
Page 24: How To Wear Safety Belts Properly
I’m a good driver, and I never drive far from home, why should wear safety belts? You may be an excellent driver, but if you’re in an accident one that isn’t your fault a good driver doesn’t protect you from things beyond your control, such as bad drivers.
Page 25: Driver Position
Driver Position This section describes the driver’s restraint system. Lap-Shoulder Belt The driver has a lap-shoulder belt. Here’s how to wear it properly. 1. Close and lock the door. 2. Adjust the seat (to see how, see “Seats” in the Index) so you can sit up straight.
Page 26 4. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. If the belt isn’t long enough, see “Safety Belt Extender” at the end of this section. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to.
Page 27 The lap part of the belt should be worn low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones. And you’d be less likely to slide under the lap belt. If you slid under it, the belt would apply force at your abdomen.
Page 28 CAUTION: You can be seriously hurt your shoulder belt is too loose. In a crash you would move forward too much, which could increase injury. The shoulder belt should fit against your body. What’s wrong with this? The belt is buckled in the wrong place. 1-16...

In wouldn’t have the full width of the belt to spread impact forces. belt is twisted, make it straight so it can work properly, or ask your dealer to Before you close the door, be sure the belt is out of the way.
Page 31: Safety Belt Use During Pregnancy
Safety Belf Use During Pregnancy Safety belts work for everyone, including pregnant women. Like all occupants, they are more likely to be seriously injured if they don’t wear safety belts. A pregnant woman should wear a lap-shoulder belt, and the lap portion should be worn as low as possible throughout the pregnancy.
Page 32: Center Passenger Position
Center Passenger Position (Bench Seat) Lap Belt If your vehicle has a bench seat, someone can sit in the center position. When you sit in a center seating position, you have a lap safety belt, which has no retractor. To make the belt longer, tilt the latch plate and pull...
Page 33 Buckle, position and release it the same way as the lap part of a lap-shoulder belt. If the belt isn’t long enough, see “Safety Belt Extender” at the end of this section. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to.
Page 34 Rear passengers who aren't safety belted can be thrown out of the vehicle in a crash. And they can strike others in the vehicle who are wearing safety belts. Buckle, position and release it the same way as the lap part of the driver's safety belt (see "Driver Position"...
Page 35: Children
Children Everyone in a vehicle needs protection! That includes infants and all children smaller than adult size. In fact, the law in every state in the United States and in every Canadian province says children up to some age must be restrained while in a vehicle.
Page 36 1-24...
Page 37: Child Restraints
Child Restraints Be sure to follow the instructions for the restraint. instructions on the restraint itself or in a booklet, or both. These restraints use the belt system in your vehicle, but the child also has to be secured within the restraint to help reduce the chance instructions that come with the infant or child restraint will show you how to .do that.
Page 38 Securing a Child Restraint in the Center Front Seat Position (Bench Seat Don’t use child restraints in the center position of a 60/40 bench seat. When you secure a child restraint in a center seating position, you’ll be using the lap belt. See the earlier section about the top strap if the child restraint has one.
Page 39 6. To tighten the belt, pull its free end while you push down on the child restraint. 7. Push and pull the child restraint in different directions to be sure it is secure. If the child restraint isn’t secure, turn the latch plate over and buckle it again.
Page 40 60/40 Split Bench Seats Don’t use a child restraint in this position. The restraint won’t work properly. Securing a Child Restraint in the Right Front Seat Position You’ll be using the lap-shoulder belt. See the earlier section about the too strap if the child restraint has one.
Page 41 If the shoulder belt goes in front of the child's face or neck, put it behind the child restraint. 4. Buckle the belt. Make sure the release button is positioned so you would be able to unbuckle the safety belt quickly if you ever had to.
Page 42: Larger Children
To remove the child restraint, just unbuckle the vehicle's safety belt and let it go back all the way. The safety belt will move freely again and be ready to work for an adult or larger child passenger. Larger Children Children who have outgrown child restraints should wear the vehicle's safety belts.
Page 43 Children who aren’t buckled up can strike other people who are. 1-31...
Page 44 What if a child is wearing a lap-shoulder belt, but the child is small that the shoulder belt is very close to the child’s face or neck? Move the child toward the center of the vehicle, but be sure that the shoulder belt still is on the child’s shoulder, so that in a crash the child’s upper body would have the restraint that belts provide.
Page 45: Safety Belt Extender
Safety Belt Extender If the vehicle’s safety belt will fasten around you, you should use it. But if a safety belt isn’t long enough to fasten, extender. It’s free. When you go in to order it, take the heaviest coat will wear, so the extender will be long enough for you.
Page 46 What’s wrong with this? The belt is torn. Torn or frayed belts may not protect you impact forces. If a belt is torn or frayed, get a new one right away. Before replacing any safety belt, see your dealer for the correct part number. You’ll need the model year and model number for your vehicle.

Your Driving and the Road Here you'll find information about driving on different kinds of roads and in varying weather conditions driving ......... . . Defensive Driving .
Page 138: Defensive Driving
Defensive Driving The best advice anyone can give about driving is: Drive defensively. Please start with a very important safety device in your vehicle: Buckle up. (See “Safety Belts” in the Index.) Defensive driving really means “be ready for anything.” On city streets, rural roads, or freeways, it means “always expect the unexpected.”...
Page 139 According to the American Medical Association, a 1 80-pound (82 kg) person who drinks three 12-ounce (355 end up with a BAC of about 0.06 percent. The person would reach the same BAC by drinlung three &ounce (120 drinks if each had 1-1/2 ounces (45 vodka.
Page 140 But it’s very important to keep in mind that the ability to drive is affected well below a BAC of 0.10 percent. Research shows that the driving skills of many people are impaired at a BAC approaching 0.05 percent, and that the effects are worse at night.
Page 141: Control Of A Vehicle
Control of a Vehicle You have three systems that make your vehicle go where you want it to go. They are the brakes, the steering and the accelerator. All three systems have to do their work at the places where the tires meet the road. Sometimes, as when you’re driving on snow or ice, it’s easy to ask more of those control systems than the tires and road can provide.
Page 142 Avoid needless heavy braking. Some people drive in spurts acceleration followed by heavy braking traffic. This is a mistake. Your brakes may not have time to cool between hard stops. Your brakes will wear out much faster if you do a lot of heavy braking.
Page 143 driver could. With rear-wheel anti-lock: If one of the rear wheels is about stop rolling, the computer will work the brakes at the rear wheels. The computer is programmed to make the most of available tire and road conditions. As you brake, your computer keeps receiving updates on wheel speed and controls braking pressure accordingly.
Page 144: Steering
Braking in Emergencies At some time, nearly every driver gets into a situation that requires hard braking. The four-wheel anti-lock system lets you steer and brake at the same time. If you have the rear-wheel anti-lock braking system, your front wheels can stop rolling when you brake very hard.
Page 145 The same thing can happen if you’re steering through a sharp curve and you suddenly accelerate. Those two control systems - steering and acceleration - can overwhelm those places where the tires meet the road and make you lose control. What should you do if this ever happens? Ease up on the brake or accelerator pedal, steer the vehicle the way you want it to go, and slow down.
Page 146 The fact that such emergency situations are always possible is a good reason to practice defensive driving at all times and wear safety belts properly. Off-Road Recovery You may find sometime that your right wheels have dropped off the edge of a road onto the shoulder while you're driving.
Page 147: Passing
Passing The driver of a vehicle about to pass another on a two-lane highway waits for just the right moment, accelerates, moves around the vehcle ahead, then goes back into the right lane again. A simple maneuver? Not necessarily! Passing another vehicle on a two-lane highway is a potentially dangerous move, since the passing vehicle occupi&...
Page 148: Loss Of Control
Check your mirrors change signal before moving out of the right lane to pass. When you are far enough ahead of the passed vehicle to see its front in your inside mirror, activate your right lane change signal and move back into the right lane.
Page 149: Driving Guidelines
While driving on a surface with reduced traction, try your best to avoid sudden steering, acceleration, or braking (including engine braking by shifting to a lower gear). Any sudden changes could cause the tires to slide. You may not realize the surface is slippery until your vehicle is skidding. Learn to recognize warning clues snow on the road to make a “mirrored surface”...
Page 150 Loading Your Vehicle for Off-Road Driving There are some important things to remember about how to load your vehicle. The heaviest things should be on the load floor and forward of your rear axle. Put heavier items as far forward as you can. Be sure the load is secured properly, so driving on the off-road terrain doesn’t toss things around.
Page 151 Getting Familiar with Off-Road Driving It’s a good idea to practice in an area that’s safe and close to home before you go into the wilderness. Off-road driving does require some new and different driving skills. Here’s what we mean. Tune your senses to different kinds of signals.
Page 152 Surface Obstacles. Unseen or hidden obstacles can be hazardous. A rock, log, hole, rut, or bump can startle you if you’re not prepared for them. Often these obstacles are hidden by grass, bushes, snow or even the rise and fall of the terrain itself.
Page 153 Driving On Off-Road Hills Off-road driving often takes you up, down, or across a hill. Driving safely on hills requires good judgment and an understanding of what your vehicle can and can’t do. There are some hills that simply can’t be driven, no matter how well built the vehicle.
Page 154 Driving Uphill Once you decide you can safely drive up the hill, you need to take some special steps. Use a low gear and get a firm grip on the steering wheel. smooth start up the hill and more power than you need, because you don’t want your wheels to start spinning or sliding.
Page 155 What should I do if my vehicle stalls, or is about to stall, and I can’t make it up the hill? If this happens, there are some things you should do, and there are some things you must not do. First, here’s what you should do: Push the brake pedal to stop the vehicle and keep it from rolling backwards.
Page 156 Suppose, after stalling, can’t do it. What should I do? Set the parking brake, put your transmission in “P” (Park) (or the manual transmission in first gear) , and turn off the engine. Leave the vehicle and go get some help. Exit on the uphill side and stay clear of the path the vehicle would take if it rolled downhill.
Page 157 Are there some things I should not do when driving down Yes! These are important because if you ignore them you could lose control-and have a serious accident. When driving downhill, avoid turns that take you across the incline of h i l l the hill.
Page 158 Driving Across an Incline Sooner or later, an off-road trail will probably go across the incline of a hill. If this happens, you have to decide whether to try to drive across the incline. Here are some things to consider: A hill that can be driven straight up or down may be too steep to drive across.
Page 159 Stalling on an Incline If your vehicle stalls when you’re crossing an incline, be sure you (and your passengers) get out on the uphill side, even if the door there is harder to open. If you get out on the downhill side and the vehicle starts to roll over, you’ll be right in its path.
Page 160 Hard packed snow and ice offer the worst tire traction. On these surfaces, it’s very easy to lose control. On wet ice, for example, the traction is so poor that you will have difficulty accelerating. And if you do get moving, poor steering and difficult braking can cause you to slide out of control.
Page 161: Drivingatnight
After Off-Road Driving Remove any brush or debris that has collected on the underbody, chassis or under the hood, These accumulations can be a fire hazard. After operation in mud or sand, have the brake linings cleaned and checked. These substances can cause glazing and uneven braking. Check the body structure, steering, suspension, wheels, tires, and exhaust system for damage.
Page 162: Driving In The Rain
Night Vision No one can see as well at night as in the daytime. But differences increase. A 50-year-old driver may require at least twice as much light to see the same thing at night as a 20-year-old. What you do in the daytime can also affect your night vision. For example, if you spend the day in bright sunshine you are wise to wear sunglasses.
Page 163 less traction. It’s always wise to go slower and be cautious if rain starts to fall while you are driving. The surface may get wet suddenly when your reflexes are tuned for driving on dry pavement. The heavier the rain, the harder it is to see. Even if your windshield wiper blades are i n good shape, a heavy rain can make it harder to see road signs and traffic signals, pavement markings, the edge of the road, and even people walking.
Page 164: Citydriving
Hydroplaning doesn’t happen often. But it can if your tires haven’t much tread or if the pressure in one or more is low. It can happen if a lot of water is standing on the road. If you can see reflections from trees, telephone poles, or other vehicles, and raindrops “dimple”...
Page 165: Freeway Driving
Try to use the freeways that rim and crisscross most large cities. You’ll save time and energy. (See the next part, “Freeway Driving.”) Treat a green light as a warning signal. A traffic light is there because the corner is busy enough to need it. When a light turns green, and just before you start to move, check both ways for vehicles that have not cleared the intersection or may be running the red light.
Page 166 Once you are moving on the freeway, make certain you allow a reasonable following distance. Expect to move slightly slower at night. When you want to leave the freeway, move to the proper lane well in advance. If you miss your exit do not, under any circumstances, stop and back up.
Page 167: Hill And Mountain Roads
High way Hypnosis Is there actually such a condition as “highway hypnosis”? Or is it just plain falling asleep at the wheel? Call it highway hypnosis, lack of awareness, or whatever. There is something about an easy stretch of road with the same scenery, along with the hum of the tires on the road, the drone of the engine, and the rush of the wind against the vehicle that can make you sleepy.
Page 168 Keep your vehicle in good shape. Check all fluid levels and also the brakes, tires, cooling system and transmission. These parts can work hard on mountain roads. Know how to go down hills. The most important thing to know is this: let your engine do some of the slowing down.
Page 169: Winter Driving
Winter Driving Here are some tips for winter driving: Have your vehiclein good shape for winter. Be sure your engine coolant mix is correct. You may want to put winter emergency supplies in your vehicle. Include an ice scraper, a small brush or broom, a supply of windshield washer fluid, a rag, some winter outer clothing, a small shovel, a flashlight, a red cloth, and a couple of reflective warning triangles.
Page 170 What’s the worst time for this? “Wet ice.” Very cold snow or ice can be slick and hard to drive on. But wet ice can be even more trouble because it may offer the least traction of all. You can get “wet ice” when it’s about freezing (32°F;...
Page 171 If You’re Caught in a If you are stopped by heavy snow, you could be in a serious situation. You should probably stay with your vehicle unless you know for sure that you are near help and you can hike through the snow. Here are some things to do to summon help and keep yourself and your passengers safe: Turn on your hazard flashers.
Page 172: Recreational Vehicle Towing (Four-Wheel Drive Only)
Run your engine only as long as you must. This saves fuel. When you run the engine, make it go a little faster than just idle. That is, push the accelerator slightly. This uses less fuel for the heat that you get and it keeps the battery charged.
Page 173 Before towing, you should: 1. Set the parking brake firmly. 2. Place the automatic transmission in “P” (Park) or me manual transmission in the lowest gear ( 1 st gear). 3. Firmly attach the vehicle being towed to the tow vehicle. Refer to the hitch manufacturer’s instructions.
Page 174: Towing A Trailer
Towing a Trailer NOTICE: Pulling a trailer improperly can damage your vehicle and result in costly repairs not covered by your warranty. To pull a trailer correctly, follow the advice in this section, and see your dealer for important information about towing a trailer with your vehicle.
Page 175 You can ask a hitch dealer about sway controls. Don’t tow a trailer at all during the first 500 miles (800 km) your new vehicle is driven. Your engine, axle or other parts could be damaged. Then, during the first 500 miles (800 km) that you tow a trailer, don’t drive over SO mph (80 kmh) and don’t make starts at full throttle.
Page 176 If you’re using a “dead-weight” hitch, the trailer tongue (A) should weigh 10% of the total loaded trailer weight (B). If you have a “weight-distributing” hitch, the trailer tongue (A) should weigh 12% of the total loaded trailer weight (B). After you’ve loaded your trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper.
Page 177 You can tow trailers to 2,000 pounds (900 kg) with a step bumper hitch, but if your trailer tongue has a V-shaped foot, your bumper could be damaged in sharp turns. Check the distance from the front edge of the foot to the middle of the hitch ball socket.
Page 178 trailer brake controller by hand to be sure the brakes are working. This lets you check your electrical connection at the same time. During your trip, check occasionally to be sure that the load is secure, and that the lights and any trailer brakes are still working, Following Distance Stay at least twice as far behind the vehicle ahead as you would when driving your vehicle without a trailer.
Page 179 Driving On Grades Reduce speed and shift to a lower gear before you start down a long or steep downgrade. If you don’t shift down, you might have to use your brakes so much that they would get hot and no longer work well. On a long uphill grade, shift down and reduce your speed to around 45 mph (70 km/h) to reduce the possibility of engine and transmission overheating.
Page 180 When You Are Reddy to Leave After Parking on a Hill 1. Apply your regular brakes and hold the pedal down while you: Start your engine; Shift into gear; and Release the parking brake. Let up on the brake pedal. 3.
Page 181 Power Winches If you wish to use a power winch on your vehicle, only use it when your vehicle is stationary or anchored. NOTICE: When operating a power winch on your vehicle always leave the transmission in the neutral position. Do not leave an automatic transmission in P (Park) or a manual transmission in gear or the transmission may be damaged.

Page 185 Other Warning Devices If you carry reflective triangles, you can set one up at the side of the road about 300 feet (1 00 m) behind your vehicle. Jump Starting If your battery has run down, you may want to use another vehicle and some jumper cables to start your vehicle.
Page 186 To Jump Start Your Vehicle: 1. Check the other vehicle. It must have a 12-volt battery with a negative ground system. NOTICE: If the other system isn’t a 12-volt system with a negative ground, both vehicles can be damaged. 2. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles aren’t touching each other.
Page 187 5 . Check that the jumper cables don’t have loose or missing insulation. If they do, you could get a shock. The vehicles could also be damaged. Before you connect the cables, here are some basic things you should know. Positive will go to positive or a metal engine part.
Page 188 Dead Battery (+) 7. Don't let the other end touch metal. Connect it to the positive terminal of the good battery. 8. Now connect the black negative terminal. Don't let the other end touch anything until the next step. The other end of the negative cable doesn't go to the dead battery.
Page 189 Now start the vehicle with the good battery and run the engine for a while. Try to start the vehicle with the dead battery. If it won’t start after a few tries, it probably needs service. Remove the cables in reverse order to prevent electrical shorting. Take care that they don’t touch each other or any other metal.

Page 202 If a Tire Goes Flat It’s unusual for a tire to “blow out” while you’re driving, especially if you maintain your tires properly. If air goes out of a tire, it’s much more likely to leak out slowly. But if you should ever have a “blowout,” here are a few tips about what to expect and what to do: If a front tire fails, the flat tire will create a drag that pulls the vehicle toward that side.

Page 247 Brakes Brake Master Cy/incier There are only two reasons why the brake fluid level in your master cylinder might go down. The first is that the brake fluid goes down to an acceptable level during normal brake lining wear. When new linings are put in, the fluid level goes back up.
Page 248 To Check Brake Fluid The fluid levels should be above “MIN.” If they aren’t, have your brake system checked to see if there is a leak. After work is done on the brake hydraulic system, make sure the levels are above “MIN”...
Page 249 Brake Wear Your vehicle has front disc brakes and rear drum brakes. Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound may come and go or be heard all the time your vehicle is moving (except when you are pushing on the brake pedal..firmly).
Page 250: Replacing Brake System Parts
Replacing Brake System Parts The braking system on a modern vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. Vehicles we design and test have top-quality GM brake parts in them, as your vehicle does when it is new.
Page 251: Bulb Replacement
Fluid Leak Check After the vehicle has been parked for awhile, inspect the surface under the vehicle for water, oil, fuel or other fluids. Water dripping from the air conditioning system after it has been used is normal. If you notice fuel leaks or fumes, the causes should be found and corrected at once.

Accelerator cables and cruise control cables should not be lubricated. Any cables that are worn or are hard to pull should be replaced. When cleaning the engine compartment with water or steam, avoid directing the flow onto the throttle linkage in a manner that would cause moisture to enter the cables.
Page 262 Lock Cylinders To be sure your locks operate properly, they must be lubricated. Refer to the Maintenance Schedule to determine how often to lubricate them and what type of lubricant to use. You should not use penetrating oils because they could wash out the factory installed lubricant and cause the lock to bind.
Page 263: Loading Your Vehicle
Engine Control Module System This system has an oxygen (02) sensor that helps keep your engine’s air-fuel mixture at a proper level. Use only unleaded fuel in your vehicle. If you use leaded fuel, you could damage your oxygen (02) sensor and affect your vehicle’s emissions.
Page 264 Using heavier suspension components to get added durability might not change your weight ratings. Ask your dealer to help you load your vehicle the right way. NOTICE: Your warranty does not cover parts or components that fail because of overloading. If you put things inside your vehicle they will go as fast as the vehicle goes.
Page 265 Payload The Payload Capacity is shown on the CertificatiodTire label. This is the maximum load capacity that your vehicle can carry. Be sure to include the weight of the people inside as part of your load. If you added any accessories or equipment after your vehicle left the factory, remember to subtract the weight of these things from the payload.
Page 266 Truck-Camper Loading Information Open your glove box and look for this label: This label will tell you if your vehicle can carry a slide-in camper, how much of a load your vehicle can carry, and how to spread out your load the right way.
Page 267 Truck Loading Information 1. Recommended location for cargo center of gravity for cargo weight rating. Refer to Truck Camper Loading Information label in the glove box for “A”and “B” dimensions. Use rear edge of load floor for measurement purposes Example of Proper Truck and Camper Match 1.
Page 268 You must weigh any accessories, trailer hitches or other equipment you add to your vehicle. Then, subtract this extra weight from the CWR. This extra weight may shorten the center of gravity zone for your vehicle. Your dealer can help you with this. If your slide-in camper and its load weigh less than the CWR, the center of gravity zone for your vehicle may be larger.
Page 269: Tires
Tires We don’t make tires. Your new vehicle comes with high quality tires made by a leading tire manufacturer. These tires are warranted by the tire manufacturers and their warranties are delivered with every new vehicle. If your spare tire is a different brand than your road tires, you will have a tire warranty folder from each of these manufacturers.
Page 270 Inflation Tire Pressure The Certification/Tire label which is on the driver’s door lock pillar, shows the correct inflation pressures for your tires, when they’re cold. “Cold” means your vehicle has been sitting for at least three hours or driven no more than a mile.
Page 271 When to Check Check your tires once a month or more. Also, check the tire pressure of the spare tire. How to Check Use a good quality pocket-type gage at the tires will not tell you the pressure, especially if you have radial tires which may look properly inflated even if they’re underinflated.
Page 272 Tire Inspection and Rotation To make your tires last longer, have mileages recommended in the Maintenance Schedule. See “Scheduled Maintenance Services” in the Index. The four wheel rotation is for aluminum wheels only. The five wheel rotation is for steel wheels only. If your vehicle has front tires with different load ratings or tread designs (such as all season vs.
Page 273 When /t’s Time for New Tires You need a new tire if: You can see the indicators at three or more places around the tire. You can see cord or fabric showing through the tire’s rubber. The tread or sidewall is cracked, cut or snagged deep enough to show cord or fabric.
Page 274 Uniform Tire Quality Grading The following information relates to the system developed by the United States National Highway Traffic Safety Administration which grades tires by treadwear, traction and temperature performance. (This applies only to vehicles sold in the United States.) Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test...
Page 275 Temperature A, B, C The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure.
Page 276 If you need to replace any of your wheels, wheel bolts, or wheel nuts, replace them only with new GM original equipment parts. This way, you will be sure to have the right wheel, wheel bolts, and wheel nuts for your GM model.
Page 277: Appearance Care
Tire Chains NOTICE: I f your vehicle has P235/75R15 or 3lxl0.50R15LT/C size tires, don’t use tire chains; they can damage your vehicle. If’ you have other size tires, use tire chains only where legal and only when you must. Use only SAE Class “S” type chains that are the proper size for your tires.

Page 280 Fabric Protection Your vehicle has upholstery and carpet that has been treated with Fabric Protector, a 3M product. Scotchgard Scotchgard by repelling oil and water, which are the carriers of most stains. Even with this protection, you still need to clean your upholstery and carpet often to keep it looking new.
Page 281 Cleaning Vinyl Use warm water and a clean cloth. Rub with a clean, damp cloth to remove dirt. You may have to do it more than once. Things like tar, asphalt and shoe polish will stain if you don’t get them off quickly.
Page 282 Glass Glass should be cleaned often. GM Glass Cleaner (GM Part No. 1050427) or a liquid household glass cleaner will remove normal tobacco smoke and dust films. Don’t use abrasive cleaners on glass, because they may cause scratches. Avoid placing decals on the inside rear window, since they may have to be scraped off later.
Page 283 Finish Care Occasional waxing or mild polishing of your vehicle may be necessary to remove residue from the paint finish. You can get GM approved cleaning products from your dealer. (See “Appearance Care and Materials” in the Index.) Your vehicle has a “basecoat/clearcoat” paint finish. The clearcoat gives more depth and gloss to the colored basecoat.
Page 284 White Side wall Tires Your GM dealer has a GM White Sidewall Tire Cleaner. You can use a stiff brush with the cleaner. Weatherstrips Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth at least every six months.
Page 285 Underbody Maintenance Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, accelerated corrosion (rust) can occur on the underbody parts such as fuel lines, frame, floor pan, and exhaust system even though they have corrosion protection. At least every spring, flush these materials from the underbody with plain water.
