It also tells you some things you should not do with safety belts. explains the Supplemental Inflatable Restraint (SIR), or air bag system. CAUTION: Don’t let anyone ride where he or she can’t wear a safety belt properly.
Page 15 Your vehicle has a light that comes on as a reminder to buckle up. (See “Safety Belt Reminder Light” in the Index.) In most states and Canadian provinces, the law says to wear safety belts. Here’s why: They work. You never know if you’ll be in a crash. If you do have a crash, you don’t know if it will be a bad one.

Page 19 driver, and I never drive far from If I’m a good home, why should I wear safety belts? You may be an excellent driver, but if you’re in accident -- even one that isn’t your fault your passengers can be hurt. Being a good driver doesn’t protect you from things beyond your control, such as bad drivers.
Page 20 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. 3. Pick up the latch plate and pull the belt across you. Don’t let it get twisted.
Page 21 5. To make the lap part tight, pull down on the buckle The lap part of the belt should be worn low and snug on end of the belt as you pull up on the shoulder belt. the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones.
Page 22 What’s wrong with this? The shoulder belt is too loose. It won’t give nearly as much protection this way. You can be seriously hurt if 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.
Page 23 What’s wrong with this? The belt is buckled in the wrong place. 1-16 You can be seriously injured if your belt is buckled in the wrong place like this. In a crash, the belt would go up over your abdomen. The belt forces would be there, not at the pelvic bones.
Page 24 What's wrong with this? The shoulder belt is worn under the arm. It should be worn over the shoulder at all times. You can be seriously injured if you wear the shoulder belt under your arm. In a crash, your body would move far forward, which would increase the chance of head and neck injury.
Page 25 What’s wrong with this? The belt is twisted across the body. 1-18 You can be seriously injured by a twisted belt. In a crash, you wouldn’t have the full width belt to spread impact forces. If a belt is twisted, make it straight so it can work properly, or ask your dealer to fix it.
Page 26 unlatch the belt, just push the button The belt should go back out of the way. Before you close the door, be sure the belt is out of the way. If you slarn the door on it, you can damage both the belt and your vehicle.

Page 29 Children who ar ~p against, or very close to, an air bag when it inflates can be seriously injured or killed. This is true even though your vehicle has reduced-force frontal air bags. Air bags plus lap-shoulder belts offer the best protection for adults, but not for young children and infants.
Page 30 How the Air Bag System Works Where are the air bags? The driver’s air bag is in the middle of the steering wheel. The right front passenger’s air bag is in the instrument panel on the passenger’s side. 1-23...
Page 31 If something is between an occupant and an air bag, the bag might not inflate properly or it might force the object into that person. The path of an inflating air bag must be kept clear. Don’t put anything between an occupant and an air bag, and don’t attach or put anything on the steering wheel hub or on or near any other air bag covering.
Page 32 What makes an air bag inflate? In an impact of sufficient severity, the air bag sensing system detects that the vehicle is in a crash. The sensing system triggers release gas from the inflator, which inflates the air bag. inflator, air bag and related hardware are all part of the air bag modules inside the steering wheel and in the instrument panel in front of the right front passenger.
Page 33 Air bags are designed to inflate only once. After they inflate, you’ll need some new parts for your air bag system. If you don’t get them, the air bag syste,m won’t be there to help protect you i n another crash. A new system will include air bag modules and possibly other parts.
Page 34 Servicing Your Air Bag-Equipped Vehicle Air bags affect how your vehicle should be serviced. There are parts of the air bag system in several places around your vehicle. You don't want the system to inflate while someone is working on your vehicle. Your dealer and the GM Service Manual have information about servicing your vehicle and the air bag system.
Page 35 Rear Seat Passengers It's very important for rear seat passengers Accident statistics show that unbelted people in the rear seat are hurt more often in crashes than those who are wearing safety belts. Rear passengers who aren't safety belted can be thrown out of the vehicle in a crash.
Page 36 2. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. When the shoulder belt is pulled out all the way, it will lock. If it does, let it go back all the way and start again.
Page 37 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 belt would apply force at your abdomen.
Page 38 To unlatch the belt, just push the button on the buckle. Rear Safety Belt Comfort Guides for Children and Small Adults Rear shoulder belt comfort guides will provide added safety belt comfort for children who have outgrown child restraints and for small adults. When installed on shoulder belt, the comfort guide pulls the belt away from the neck and head.
Page 39 2. Slide the guide under and past the belt. The elastic cord must be under the belt. Then, place the guide over the belt, and insert the two edges of the belt into the slots of the guide. 1-32 Be sure that the belt is not twisted and it lies flat. The elastic cord must be under the belt and the guide on top.
Page 40 4. Buckle, position and release the safety belt as described in “Rear Seat Outside Passenger Positions” earlier in this section. Make sure that the shoulder belt crosses the shoulder. To remove and store the comfort guides, squeeze the belt edges together so that you can take them out from the guides.

Make sure the this release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly you ever had to.
Page 43 Smaller children and babies should always be restrained in a child or infant restraint. The instructions for the restraint will say whether it is the right type and size for your child. A very young child’s hip bones are so small that a regular belt might not stay low on the hips, as it should.
Page 44 Never hold a baby in your arms while riding in a vehicle. A baby doesn’t weigh much crash. During a crash a baby will become so heavy you can’t hold it. For example, in a crash CAUTION: (Continued) at only 25 mph (40 km/h), a 12-lb. (5.5 kg) baby will suddenly become a 240-lb.

Page 58 CAUTION: Never do this. Here a child is sitting in a seat that has a lap-shoulder belt, but the shoulder part is behind the child. If the child wears the belt in this way, in a crash the child might slide under the belt. The belt’s force would then be applied right on the child’s abdomen.
Page 59 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, your dealer will order you an extender. It’s free. When you go in to order it, take the heaviest coat you will wear, so the extender will be long enough for you.

Page 160 Section 4 Your Driving and the Road Here you’ll find information about driving on different kinds of roads and in varying weather conditions, We’ve also included many other useful tips on driving. 4- 2 Defensive Driving Drunken Driving Control of Vehicle Braking Steering...
Page 161 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 162 Drunken Driving Death and injury associated with drinking and driving is a national tragedy. It’s the number one contributor to the highway death toll, claiming thousands of victims every year. Alcohol affects four things that anyone nee.ds to drive a vehicle: Judgment Muscular Coordination Vision...
Page 163 It's the amount of alcohol that counts. For example, if the same person drank three double martinis (3 ounces or 90 ml of liquor each) within an hour, the person's BAC would be close to 0.12 percent. A person who consumes food just before or during drinking somewhat lower BAC level.
Page 164 The body takes about an hour to rid itself of the alcohol in one drink. No amount of coffee or number of cold showers will speed that up. “I’ll be careful” isn’t the right answer. What if there’s an emergency, a need to take sudden action, as when a child darts into the street? A person with even a moderate BAC might not be able to react quickly enough to avoid the collision.
Page 165 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 166 And, of course, actual stopping distances vary greatly with the surface of the road (whether it‘s pavement or gravel); the condition of the road (wet, dry, icy); tire tread; the condition of your brakes; the weight of the vehicle and the amount of brake force applied. Avoid needless heavy braking.
Page 167 Here’s how anti-lock works. Let’s say the road is wet. You’re driving safely. Suddenly an animal jumps out in front of you. You slam on the brakes. Here’s what happens with ABS. A computer senses that wheels are slowing down. If one of the wheels is about to stop rolling, the computer separately work the brakes at each front wheel and at both rear wheels.
Page 168 Re,member: Anti-lock doesn’t change the time you need to get your foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, you won’t have time to apply your brakes if that vehicle suddenly slows or stops.
Page 169 The traction you can get in a curve depends on the condition your tires and the road surface, the angle at which the curve is banked, and YOLK you’re in a curve, speed is the one factor you can control. Suppose you’re steering through a sharp curve.
Page 170 An emergency like this requires close attention and a quick decision. If you are holding the steering wheel at the recommended 9 and 3 o'clock positions, you can turn it a full 180 degrees very quickly without removing either hand. But you have to act fast, steer quickly, and just as quickly straighten the wheel once you have avoided the object.
Page 171 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 vehicle ahead, then goes back into the right lane again. simple maneuver? Not necessarily! Passing another vehicle on a two-lane highway is a potentially dangerous move, since the passing vehicle occupies the same lane as oncoming traffic for several seconds.
Page 172 Check your mirrors, glance over your shoulder and start your left lane 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 173 If your vehicle starts to slide, ease your foot off the accelerator pedal and quickly steer the way you want the vehicle to go. you start steering quickly enough, your vehicle may straighten out. Always be ready for a second skid if it occurs. Of course, traction is reduced when water, snow, ice, gravel or other material is o n the road.
Page 174 Off-Road Driving with Your GM Four-Wheel-Drive Vehicle Also, see "Anti-Lock Brakes" in the Index. Off-road driving can be great fun. But it does have some definite hazards. The greatest of these is the terrain itself. "Off-roading" means you've left the great North American road system behind.
Page 175 Cargo on the load floor piled higher than the seatbacks can be thrown forward during a sudden stop. You or your passengers could be injured. Keep cargo below the top of the seatbacks. Unsecured cargo on the load floor can be tossed about when driving over rough terrain.
Page 176 Traveling to Remote Areas makes sense to plan your trip, especially when going to a remote area. Know the terrain and plan your route. You are much less likely to get bad surprises. Get accurate maps of trails and terrain. Try to learn of any blocked or closed roads.
Page 177 Scanning the Terrain Off-road driving can take over many different kinds of terrain. You need to be familiar with the telrain and its many different features. Here are some things to consider. S~lr$uce Conditions. Off-roading can take you over hard-packed dirt, gravel, rocks, grass, sand, mud, snow or ice.
Page 178 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 your vehicle can and can't do. an understanding of what There are some hills that simply can't be driven, no matt how well built the vehicle.
Page 179 Driving Uphill Once you decide 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. Get a smooth start up the hill and try to maintain your speed.
Page 180 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 from rolling backwards.
Page 181 Driving Downhill When off-roading takes you uownhill, you'll want to consider a number of things: How steep is the downhill'? Will I vehicle control? What's the surface like'? Smooth'? Rough'? Slippery'? Hard-packed dirt'? Gravel? Are there hidden surface obstacles'! Ruts? Logs? Boulders'? What's at the bottom of the hill'! Is there a hidden creek bank or even...
Page 182 I likely stall when going downhill? It's much nm-e likely to happen going uphill. happens going downhill, here's what to Stop your vehicle by applying the regular brakes. Apply the parking brake. Shift to PARK ( P ) and. while still braking. restart the engine.
Page 183 Driving across an incline that’s too steep will make your vehicle roll over. You could be seriously injured or killed. If you have any doubt about the steepness of the incline, don’t drive across it. Find another route instead. What if I’m driving across an incline that’s not too steep, but I hit some loose gravel and start to slide downhill.
Page 184 Getting out on the downhill (low) side of stopped across an incline is dangerous. If the vehicle rolls over, you could be crushed or killed. Always get out on the uphill (high) side of the vehicle and stay well clear of the rollover path. Driving in Mud, Sand, Snow or Ice When you drive in mud, snow or sand, your wheels won’t get good traction.
Page 185 Driving in Water Light rain causes n o special off-road driving problems. But heavy rain can mean flash flooding, and flood waters demand extreme caution. Find how deep the water is before you drive through o u t If' it's deep enough to cover your wheel hubs. axles or exhaust pipe, don't try you probably won't get through.
Page 186 Your vehicle will require more frequent service due to off-road use. Refer to the Maintenance Schedule for additional information. Drivin at Night Night driving is more dangerous than day driving. One reason is that some drivers are likely to be impaired by alcohol or drugs, with night vision problems.
Page 187 can be temporarily blinded by approaching headlamps. It can take a second or two, or even several seconds, for your eyes to readjust to the dark. When you are faced with severe glare (as from a driver who doesn’t lower the high beams, or a vehicle with misaimed headlamps), slow down a little.
Page 188 The heavier the rain, the harder it is to see. Even if your windshield wiper blades are in 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 189 Hydroplaning Hydroplaning is dangerous. So much water can build up under your tires that they can actually ride on the water. This can happen if the road is wet enough and you’re going fast enough. When your vehicle is hydroplaning, it has little or no contact with the road.
Page 190 City Driving One of the biggest problems with city streets is the amount of traffic on them. You'll want to watch out for what the other drivers are doing and pay attention to traffic signals. Here are ways to increase your safety in city driving: Know the best way get to where you are going.
Page 191 Freeway Driving Mile for mile, freeways (also called thruways, parkways, expressways, turnpikes or superhighways) are the safest of all roads. But they have their own special rules. The most important advice on freeway driving is: Keep up with traffic and keep to the right. Drive at the same speed most of the other drivers are driving.
Page 192 The exit speed is usually posted. Reduce your speed according to your speedometer’ not your sense of motion. After driving for any distance at higher speeds, you may tend to think you are going slower than you actually are. Before Leaving on a Long Trip Make sure you’re ready.
Page 193 Highway Hypnosis there actually such a condition 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 the engine, and the rush of the wind against the vehicle that can make you sleepy.
Page 194 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.

But trailering is different than just driving your vehicle by itself. Trailering means changes in handling, durability and fuel economy. Successful, safe trailering takes correct equipment, and it has to be used properly.
Page 204 Weight of the Trailer How heavy can a trailer safely be? you plan to use your rig. For It depends on how example, speed, altitude, road grades, outside temperature and how much your vehicle is used to pull a trailer are all important. And, it can also depend on any special equipment that you have on your vehicle.
Page 205 If you’re using a weight-carrying hitch, the trailer tongue (A) should weigh 10 percent of the total loaded trailer weight (B). If you’re using a weight-distributing hitch, the trailer tongue (A) should weigh 12 percent 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 206 Safety Chains You should always attach chains between y o ~ ~ r and yo~lr trailer.

Page 226 NOTICE: In cold weather, water can freeze and crack the engine, radiator, heater core and other parts. Use the recommended coolant and the proper coolant mixture. CAUTION: You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol and it will burn if the engine parts are hot enough.
Page 227 CAC JON: Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They are under pressure, and if you turn the radiator even a little pressure cap they can come out at high speed. Never turn the cap when the cooling system, including the radiator pressure cap, is hot.
Page 228 How to Add Coolant to the Radiator I . You can remove the radiator pressure cap when the cooling including the radiator pressure cap and system. upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise until it first stops. (Don’t press down while turning the pressure cap.) If you hear a hiss, wait for that to stop.
Page 229 3. Fill the radiator with the proper DEX-COOL@ coolant mixture, up to the base of the filler neck. (See "Engine Coolant" in the Index for more information about the proper coolant mixture.) 5-18 4. Then fill the coolant recovery tank to the ADD mark. 5.
Page 230 ..6. Start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fan. 7. By this time, the coolant level inside the radiator filler neck may be lower. If the level is lower, add more of the proper DEX-COOL@ coolant mixture through the filler neck until the level reaches the base of the filler neck.
Page 231 Engine Fan Noise This vehicle has a clutched engine cooling fan. When the clutch is engaged, the fan spins faster to provide more air to cool the engine. In most everyday driving conditions, the clutch is not engaged. This improves fuel economy and reduces fan noise.
Page 232 Changing a Flat Tire If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your hazard warning flashers. CAUTION: Changing a tire can cause an injury. The v d c l e can slip off the jack and roll over you or other people.

Page 252 Fuels in Foreign Countries If you plan on driving in another country outside the United States or Canada, the proper fuel may be hard to find. Never use leaded gasoline or any other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel wouldn’t be covered by your warranty.
Page 253 Gasoline vapor is highly flammable. It burns violently, and that can cause very bad injuries. Don’t smoke if you’re near gasoline or refueling your vehicle. Keep sparks, flames and smoking materials away from gasoline. While refueling, hang the cap by the tether from the hook on the filler door.
Page 254 When you put the cap back on, turn it to the right (clockwise) until you hear a clicking sound. Make sure you fully install the cap. The diagnostic system can determine if the fuel cap has been left improperly installed. This would allow fuel to evaporate into the atmosphere.
Page 255 Checking Things Under the Hood Things that burn can get on hot engine parts and start a fire. These include liquids like gasoline, oil, coolant, brake fluid, windshield washer and other fluids, and plastic or rubber. You or others could be burned. Be careful not to drop things that will burn onto hot engine.

Page 262 CAUTION: Operating the engine with the air cleaner off can cause you or others to be burned. The air cleaner not only cleans the air, it stops flame if the engine backfires. If it isn’t there, and the engine backfires, you could be burned. Don’t drive with it off, and be careful working on the engine with the air cleaner off.
Page 263 How to Check Because this operation can be a little difficult, you may choose to have this done at your Service Department. If you do it yourself, be sure follow all the instructions here, or you could get a false reading on the dipstick.
Page 264 Checking Transmission Fluid Hot Get the vehicle warmed up by driving about 15 miles (24 km) when outside temperatures are above 50°F (10°C). If it's colder than 50°F (lO"C), drive the vehicle in THIRD (3) until the engine temperature gage moves and then remains steady for 10 minutes.
Page 265 2. Push it back in all the way, wait three seconds and then pull it back out again. 3. Check both sides of the dipstick, and read the lower level. The fluid level must be in the COLD area for a cold check or in the HOT area or cross-hatched area for a hot check.

Page 270 NOTICE: If you use an improper coolant mixture, your engine could overheat and be badly damaged. The repair cost wouldn’t be covered by your warranty. Too much water in the mixture can freeze and crack the engine, radiator, heater core and other parts.
Page 271 CAUTION: Turning the radiator pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly. With the coolant recovery tank, you will almost never have to add coolant at the radiator. Never turn the radiator pressure cap little when the engine and radiator are hot.
Page 272 Thermostat Engine coolant temperature is controlled by a thermostat in the engine coolant system. The thermostat stops the flow of coolant through the radiator until the coolant reaches a preset temperature.

Page 273 Windshield Washer Fluid What to Use When you need windshield washer fluid, be sure to read the manufacturer’s instructions before use. If you will be operating your vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing.
Page 274 Brakes Brake Fluid Your brake master cylinder reservoir is here. DOT-3 brake fluid. with There are only two reasons why the brake fluid level in the reservoir might go down. The first is that the brake fluid goes down to an acceptable level during normal brake lining wear.
Page 275 Checking Brake Fluid You can check the brake fluid without taking off the cap. Just look at the brake fluid reservoir. The fluid level should be above MIN. If it isn’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 level is above the MTN but not over the MAX mark or the top of the window on the side...
Page 276 NOTICE: Using the wrong fluid can badly damage brake system parts. For example, just a few drops of mineral-based oil, such as engine oil, in your brake system can damage brake system parts so badly that they’ll have to be replaced.
Page 277 Some driving conditions or climates may cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with your brakes. Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake pads for wear and evenly torque wheel nuts in the proper sequence to GM specifications.

Page 283 Tires Your new vehicle comes with high-quality tires made by a leading tire manufacturer. If you ever have questions about your tire warranty and where to obtain service, see your GMC Warranty booklet for details.
Page 284 Poorly maintained and improperly used tires are dangerous. Overloading your tires can cause overheating as a result of too much friction. You could have an air-out and a serious accident. See “Loading Your Vehicle” in the Index. Underinflated tires pose the same danger as overloaded tires.
Page 285 NOTICE: (Continued) If your tires have too much air (overinflation), you can get the following: Unusual wear Bad handling Rough ride Needless damage from road hazards. When to Check Check your tires once a month or more. Also, check the tire pressure of the spare tire.
Page 286 When rotating your tires, always use one of the correct rotation. patterns shown here. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Certificationflire label. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque”...
Page 287 When It’s Time for New Tires One way to tell when it’s time for new tires is to check the treadwear indicators, which will appear when your tires have only 1/16 inch (1.6 mm) or less of tread remaining. You need a new tire if any of the following statements are true: You can see the indicators at three or more places around the tire.
Page 288 Mixing tires could cause you to lose control while driving. If you mix tires of different sizes or types (radial and bias-belted tires), the vehicle may not handle properly, and you could have a crash. Using tires of different sizes may also cause damage to your vehicle.
Page 289 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 course. For example, a tire graded 150 would wear one and a half (1 1/2) times as well on the government course as a tire graded 100.
Page 290 This way, you will be sure to have the right wheel, wheel bolts and wheel nuts for your GMC model. Using the wrong replacement wheels, wheel bolts O r wheel nuts on Your vehicle can be dangerous-...
Page 291 NOTICE: The wrong wheel can also cause problems with bearing life, brake cooling, speedometer or odometer calibration, headlamp aim, bumper height, vehicle ground clearance and tire clearance to the body and chassis. See “Changing a Flat Tire” in the Index more information.
Page 292 Appearance Care Remember, cleaning products can be hazardous. Some are toxic. Others can burst into flame if you strike a match or get them on a hot part of the vehicle. Some are dangerous if you breathe their fumes in a closed space. When you use anything from a container to clean your vehicle, be sure to follow the manufacturer’s warnings and instructions.
Page 293 Cleaning the Inside of Your Vehicle Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl, leather, plastic and painted surfxes with a clean, damp cloth. Your dealer has two cleaners, Multi-Purpose Interior Cleaner and Capture Non-Solvent Dry Spot and Soil Remover for cleaning fabric and carpet.
Page 294 Special Fabric Cleaning Problems Stains caused by such things as catsup, coffee (black), egg, fruit, fruit juice, milk, soft drinks, vomit, urine and blood can be removed as follows: 1. Carefully scrape off excess stain? then sponge the soiled area with cool water. 2.
