Head Restraints CAUTION: Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts can't do their job when you're reclined like this. The shoulder belt can't do its job. In a crash, you could go into it, receiving neck or other injuries - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 20

You never know if you'll be in a crash. If you do have a crash, you don't know if it will - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 23
Why Safety Belts Work When you ride in or on anything, you go as fast as it goes. Put someone on it. Take the simplest vehicle. Suppose it's just a seat on wheels. 1-11 - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 24
Get it up to speed. Then stop the vehicle. The rider doesn't stop. The person keeps going until stopped by something. In a real vehicle, it could be the windshield ... 1-12 - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 25
or the instrument panel ... or the 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. 1-13 - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 26
many vehicles today and will be in most of them in the future. But they are supplemental systems only; so they work with safety belts -- not instead of them. Every air bag system ever offered for sale has required the use of safety belts. Even if you're in a vehicle that has - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 27
If a child will be riding in your vehicle, see the part of this manual called "Children." Follow those rules for everyone's protection. First part describes the driver's restraint system.

These parts of the body are best able to take belt restraining forces. The safety belt locks if there's - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 29
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. A: The shoulder belt is too loose. It won't give nearly as much protection this way. 1-17 - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 30
Q: What's 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. Always buckle your belt - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 31
Q: What's 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 - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 32
. In a crash, you wouldn't 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. A: The belt is twisted across the - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 33
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. To unlatch the belt, just push the button on the buckle. The belt should go back out of the way. Before you close the door, be sure - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 34
Air Bag Systems This part explains the frontal and side impact air bag systems. Your vehicle has four air bags -- a frontal air bag for the driver, another frontal air bag for the right front passenger, a side impact air The right front passenger's safety belt works the same way as the driver's - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 35

see the part of this manual called "Children." There is an air bag readiness light on the instrument panel, which shows the air bag symbol. The system checks the air bag electrical system for malfunctions. The light tells you if there is an electrical problem. See "Air Bag Readiness Light" in the - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 37
How the Air Bag Systems Work Where are the air bags? The right front passenger's frontal air bag is in the instrument panel on the passenger's side. The driver's frontal air bag is in the middle of the steering wheel. 1-25 - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 38
The driver's side impact air bag is in the side of the driver's seatback closest to the door. The right front passenger's side impact air bag is in the side of the passenger's seatback closest to the door. 1-26 - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 39

The inflator, air bag and related hardware are all part of the air bag modules inside the steering wheel, instrument panel and the side of the front seatbacks closest to the door.

In fact, the guides, squeeze the belt edges together so that you can take them out of the guides. Slide the guide back on its storage clip located between the interior body - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 49
CAUTION: (Continued) 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 on a person's arms. A baby should be secured in an appropriate restraint. CAUTION: People should never hold a baby in their arms while riding in a vehicle. A - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 50

An infant car bed (A), a special bed made for use in a motor vehicle, is an infant restraint system designed to restrain or position a child on a continuous flat surface. Make sure that the infant's head rests toward the center of the vehicle. A rear-facing infant seat (B) provides restraint with - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 53
A forward-facing child seat (C-E) provides restraint for the child's body with the harness and also sometimes with surfaces such as T-shaped or shelf-like shields. A booster seat (F-G) is a child restraint designed to improve the fit - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 54
Q: A: How do child restraints work? A child restraint system is any device designed for use in a motor vehicle to restrain, seat, or position children.

To assist you in locating the lower anchors for this child restraint system, each seating position with the LATCH system will - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 58
In order to use the system, you need either a forward-facing child restraint that has attaching points (B) at its base and a top tether anchor (C), or a rear-facing child restraint that has attaching points (B), as shown here. With this system, use the LATCH system instead of the vehicle's safety - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 59

The shoulder belt should not cross the face or neck. The lap belt should fit snugly below the hips, just - 2003 Chevrolet TrailBlazer | Owner's Manual - Page 67
vehicle. If the child is sitting in the center rear seat passenger position, move the child toward the safety belt buckle.
