2003 CHEVROLET C/K Owners Manual

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. That could cause serious or
fatal injuries.
Wherever the child sits, the lap portion of the belt
should be worn low and snug on the hips, just touching
the child's thighs. This applies belt force to the child's
pelvic bones in a crash.

1-67
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. The extender will
be just for you, and just for the seat in your vehicle that
you choose. Don't let someone else use it, and use it
only for the seat it is made to fit. To wear it, just attach it
to the regular safety belt.
Checking Your 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.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt is
torn or frayed, get a new one right away.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)

Replacing Restraint System Parts
After a Crash
CAUTION:
A crash can damage the restraint systems in your
vehicle. A damaged restraint system may not
properly protect the person using it, resulting in
serious injury or even death in a crash. To help
make sure your restraint systems are working
properly after a crash, have them inspected and
any necessary replacements made as soon as
possible.
If you've had a crash, do you need new belts?
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, then you need new parts.
If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have safety belt
or seat parts repaired or replaced. New parts and repairs
may be necessary even if the belt wasn't being used at
the time of the collision.
If an air bag inflates, you'll need to replace air bag
system parts. See the part on the air bag system earlier
in this section.

Windows
CAUTION:
Leaving children in a vehicle with the windows
closed is dangerous. A child can be overcome by
the extreme heat and can suffer permanent
injuries or even death from heat stroke. Never
leave a child alone in a vehicle, especially with the
windows closed in warm or hot weather.

2-3 Manual Windows
Turn the hand crank on each door to raise or lower
the window.
Power Windows (If Equipped)
If your vehicle is equipped with power windows, the
switches are located on each of the side doors. The
driver's door also has a switch for the passenger's
window.
If your vehicle is a Crew Cab model with power
windows, there will be switches located on the rear
doors as well.
However, the driver's door will have four switches
located on it that can control all windows.
Your power windows will work when the ignition has
been turned to ACCESSORY or RUN.
Press the rear of the switch with the power window
symbol on it to lower the window and the front of the
switch to raise the window.

2-4
Express-Down Feature
The driver's window also has an express
-down feature
that allows the window to be lowered without holding
down the switch. Press and hold the rear of the window
switch labeled AUTO for one second to activate the
express
-down mode.
The express
-down mode can be cancelled at any time by
pressing the front of the switch. To open the window
part way, lightly tap the switch until the window is at the
desired position.
Lockout Feature (If Equipped)
If you have a Crew Cab model with power windows, the
driver's door will have a lockout feature. When
engaged, this feature will prevent all window switches,
except the driver's window switches, from operating.
This switch is located above the four window switches
on the driver's door.. When the switch is not engaged,
all windows will return to normal operation.
Sliding Rear Window (If Equipped)
To open the sliding rear window, unlock the latch
lever by pulling the lever toward the driver's side of
the vehicle.
To close the window, slide the window toward the
passenger's side of the vehicle. The latch lever will
automatically snap onto the latch plate. Try to open the
window without releasing the latch lever to be sure the
window is in the locked position.

2-5
Keys
CAUTION:
Leaving children in a vehicle with the ignition
key is dangerous for many reasons. A child or
others could be badly injured or even killed.
They could operate the power windows or other
controls or even make the vehicle move. Don't
leave the keys in a vehicle with children.
