Page 8: Front Seats
Front Seats CAUTION: Manual Seats You can lose control of the vehicle if you try to adjust a manual driver’s seat while the vehicle is moving. The sudden movement could startle and confuse you, or make you push a pedal when you do not want to.
Page 9: Manual Lumbar
Manual Lumbar To get more support in the lumbar area of your back, turn the lumbar adjustment knob. The knob is located on the inboard side of the driver’s seatback and the outboard side of the passenger’s seatback.
Page 10: Reclining Seatbacks
Reclining Seatbacks CAUTION: You can lose control of the vehicle if you try to adjust a manual driver’s seat while the vehicle is moving. The sudden movement could startle and confuse you, or make you push a pedal when you do not want to.
Page 11 CAUTION: Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts cannot do their job when you are reclined like this. The shoulder belt cannot do its job. In a crash, you could go into it, receiving neck or other injuries.
Page 12: Air Suspension Seats
Air Suspension Seats Isolator Lock Lever Your vehicle may have an air suspension seat. The lever is located on There are two ways you can adjust the seat. the inboard side of the driver’s seat. Height Adjustment The height adjustment is controlled by the air suspension valve.
Page 13: Safety Belts
Center Seat Safety Belts Your vehicle may have a center seat. Safety Belts: They Are for Everyone To fold the seatback down, pull the lever, located on the right side of the seat. This part of the manual tells you how to use safety belts properly.
Page 14 In most states and in all Canadian provinces, the law says to wear safety belts. Here is why: CAUTION: They work. You never know if you will be in a crash. If you do It is extremely dangerous to ride in a have a crash, you do not know if it will be a cargo area, inside or outside of a vehicle.
Page 15 Why Safety Belts Work Aren’t safety belts for kids? Yes. And they are for adult truckers, and anyone else who rides in your vehicle. If the vehicle hits something, it stops – right then. But nothing stops the people. They keep moving. Here is why: when your vehicle goes, say, 30 mph (50 km/h), so do you and your passengers.
Page 16 Then something will stop them. It could be the Or it could be the instrument panel. windshield. Now, what if you and your passengers were to give that big vehicle a chance to deal with the force of the impact, instead of you?
Page 17: Questions And Answers About Safety Belts
Questions and Answers About Safety Belts Will I be trapped in the vehicle after an accident if I am wearing a safety belt? You could be — whether you are wearing a safety belt or not. But you can unbuckle a safety belt, even if you are upside down.
Page 18: How To Wear Safety Belts Properly
How to Wear Safety Belts Properly This part is only for people of adult size. Be aware that there are special things to know about safety belts and children. And there are different rules for smaller children and babies. If a child will be riding in your vehicle, see Older Children on page 30 or Infants and Young Children on page 33.
Page 19 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 is not long enough, see Safety Belt Extender on page 29. 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 20 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 would be less likely to slide under the lap belt. If you slid under it, the belt would apply force at your abdomen.
Page 21 What is wrong with this? CAUTION: 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. The shoulder belt is too loose. It will not give nearly as much protection this way.
Page 22 What is wrong with this? CAUTION: You can be seriously hurt if your lap belt is too loose. In a crash, you could slide under the lap belt and apply force at your abdomen. This could cause serious or even fatal injuries. The lap belt should be worn low and snug on the hips, just touching the thighs.
Page 23 What is wrong with this? CAUTION: 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. This could cause serious internal injuries.
Page 24 What is wrong with this? CAUTION: You can be seriously injured if you wear the shoulder belt under your arm. In a crash, your body would move too far forward, which would increase the chance of head and neck injury. Also, the belt would apply too much force to the ribs, which are not as strong as shoulder bones.
Page 25 What is wrong with this? CAUTION: You can be seriously injured by a twisted belt. In a crash, you would not have the full width of the 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: Shoulder Belt Height Adjustment
Shoulder Belt Height Adjustment Before you begin to drive, move the shoulder belt height adjuster to the height that is right for you. Adjust the height so that the shoulder portion of the belt is centered on your shoulder. The belt should be away from your face and neck, but not falling off your shoulder.
Page 27: Safety Belt Use During Pregnancy
Safety Belt Use During Pregnancy A pregnant woman should wear a lap-shoulder belt, and the lap portion should be worn as low as Safety belts work for everyone, including pregnant possible, below the rounding, throughout the women. Like all occupants, they are more likely pregnancy.
Page 28: Center Passenger Position
Right Passenger Position The right passenger’s safety belt works the same way as the driver’s safety belt. See Driver Position on page 18. Center Passenger Position Lap Belt If your vehicle has a center 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.
Page 29: 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 is not long enough, your dealer will order you an extender. When you go in to order it, take the heaviest coat you will wear, so the extender will be long enough for you.
Page 30: Child Restraints
Child Restraints What is the proper way to wear safety belts? Older Children If possible, an older child should wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide. The shoulder belt should not cross the face or neck.
Page 31 What if a child is wearing a lap-shoulder belt, but the child is so 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 32 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.
Page 33: Infants And Young Children
Infants and Young Children CAUTION: Everyone in a vehicle needs protection! This includes infants and all other children. Neither the distance traveled nor the age and size of the Children can be seriously injured or traveler changes the need, for everyone, to use strangled if a shoulder belt is wrapped safety restraints.
Page 34 CAUTION: People should never hold a baby in their arms while riding in a vehicle. A baby does not weigh much — until a crash. During a crash a baby will become so heavy it is not possible to hold it. For example, in a crash at only 25 mph (40 km/h), a 12 lb (5.5 kg) baby will suddenly become a 240 lb (110 kg) force...
Page 35 What are the different types of add-on child restraints? CAUTION: Add-on child restraints, which are purchased by the vehicle’s owner, are available in four basic Newborn infants need complete support, types. Selection of a particular restraint should including support for the head and neck. take into consideration not only the child’s This is necessary because a newborn weight, height, and age but also whether or not...
Page 36 CAUTION: The body structure of a young child is quite unlike that of an adult or older child, for whom the safety belts are designed. A young child’s hip bones are still so small that the vehicle’s regular safety belt may not remain low on the hip bones, as it should.
Page 37: Child Restraint Systems
Child Restraint Systems A rear-facing infant seat (B) provides restraint with the seating surface against the back of the An infant car bed (A), a special bed made for use infant. The harness system holds the infant in a motor vehicle, is an infant restraint system in place and, in a crash, acts to keep the infant designed to restrain or position a child on a positioned in the restraint.
Page 38 A forward-facing child seat (C-E) provides restraint A booster seat (F-G) is a child restraint designed for the child’s body with the harness and also to improve the ﬁt of the vehicle’s safety belt sometimes with surfaces such as T-shaped system.
Page 39 Securing an Add-on Child Restraint in How Should I Use a Child Restraint? the Vehicle A child restraint system is any device designed for use in a motor vehicle to restrain, seat, or position children. A built-in child restraint CAUTION: system is a permanent part of the motor vehicle.
Page 40 When securing an add-on child restraint, refer to the child’s body. A shelf- or armrest-type shield has the instructions that come with the restraint straps that are attached to a wide, shelf-like shield which may be on the restraint itself or in a booklet, that swings up or to the side.
Page 41 Lower Anchors and Tethers for In Canada, the law requires that forward-facing child restraints have a top tether, and that Children (LATCH) the tether be attached. Some child restraints have a LATCH system. As Your vehicle does not have lower anchors or top part of the LATCH system, your child restraint may tether anchors to secure a child restraint with have lower attachments and/or a top tether.
Page 42 Securing a Child Restraint in Your or if the instructions that come with the restraint say that the top tether must be anchored. See Lower Medium Duty Vehicle Anchors and Tethers for Children (LATCH) on page 41 if the child restraint has one. We know securing a child can present real problems in a medium-duty vehicle like yours.
Page 43: Restraint System Check
Restraint System Check Checking the Restraint Systems Now and then, make sure the safety belt reminder light and all your belts, buckles, latch plates, retractors, and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired.
Page 44: Replacing Restraint System Parts After A Crash
Replacing Restraint System Parts If you have had a crash, do you need new belts? After a Crash After a very minor collision, nothing may be necessary. But if the belts were stretched, as they would be if worn during a more severe crash, CAUTION: then you need new parts.
