Driver Position
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here is how to wear
it properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To see
how, see “Seats” in the Index.
3. Pick up the latch plate and pull the belt across you.
Do not let it get twisted.The shoulder belt may lock if you pull the belt
across you very quickly. If this happens, let the belt
go back slightly to unlock it. Then pull the belt
across you more slowly.
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, seeSafety Belt
Extender on page 1-26.
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.
5. To make the lap part tight, pull up on the
shoulder belt.

If your vehicle has a roof-mounted airbag for the right
front passenger and the person directly behind that
passenger, it is located in the ceiling above the
side windows.
{CAUTION:
If something is between an occupant and an
airbag, the bag might not inate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inating airbag must be kept clear. Do not put
anything between an occupant and an airbag,
and do not attach or put anything on the
steering wheel hub or on or near any other
airbag covering. And, if your vehicle has
roof-mounted airbags, never secure anything
to the roof of your vehicle by routing the rope
or tiedown through any door or window
opening. If you do, the path of an inating side
impact airbag will be blocked. The path of an
inating airbag must be kept clear.

What Will You See After an Airbag
Inates?
After an airbag inates, it quickly deates, so quickly
that some people may not even realize the airbag
inated. Some components of the airbag module — the
steering wheel hub for the driver’s airbag, the
instrument panel for the right front passenger’s bag or
the ceiling of your vehicle near the side windows — will
be hot for a short time. The parts of the bag that
come into contact with you may be warm, but not too
hot to touch. There will be some smoke and dust coming
from the vents in the deated airbags. Airbag ination
does not prevent the driver from seeing or being able to
steer the vehicle, nor does it stop people from leaving
the vehicle.
{CAUTION:
When an airbag inates, there is dust in the
air. This dust could cause breathing problems
for people with a history of asthma or other
breathing trouble. To avoid this, everyone in
the vehicle should get out as soon as it is safe
to do so. If you have breathing problems but
can not get out of the vehicle after an airbag
inates, then get fresh air by opening a
window or a door. If you experience breathing
problems following an airbag deployment, you
should seek medical attention.
Your vehicle has a feature that will automatically unlock
the doors and turn the interior lamps on when the
airbags inate (if battery power is available). You can
lock the doors again and turn the interior lamps off
by using the door lock and interior lamp controls.

When a new vehicle is delivered, the dealer provides
the owner with a pair of identical keys and a key
code number.The key code number tells your dealer or a qualied
locksmith how to make extra keys. Keep this number in
a safe place. If you lose your keys, you’ll be able to
have new ones made easily using this number.
Your selling dealer should also have this number.
Notice:If you ever lock your keys in your vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.
If you ever do get locked out of your vehicle, call the
GM Roadside Assistance Center. SeeRoadside
Assistance Program on page 7-6.

Remote Keyless Entry System
Operation
If your vehicle has this feature, you can lock and unlock
your doors from about 3 feet (1 m) up to 30 feet
(9 m) away using the remote keyless entry transmitter
supplied with your vehicle.
K(Unlock):Press unlock
for the driver’s door to
unlock automatically, the
parking lamps to ash
and the interior lights to go
on. Press the unlock
button a second time within
three seconds to unlock
all the doors.
You can program different feedback settings through the
Driver Information Center (DIC). For more information
seeDriver Information Center (DIC) on page 3-51.
Q(Lock):Press lock to lock all the doors. Press lock
again within three seconds and the horn will chirp.
L(Panic):Press the horn symbol to make the horn
sound. The headlamps and taillamps will ash for up
to 30 seconds. This can be turned off by pressing
the horn button again, by waiting for 30 seconds, or by
starting the vehicle.
Matching Transmitter(s) to Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can
be purchased through your dealer. Remember to bring
any remaining transmitters with you when you go to
your dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock
your vehicle. Each vehicle can have a maximum of
four transmitters matched to it.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers — especially children — can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle will not open it. You increase the
chance of being thrown out of the vehicle
in a crash if the doors are not locked. So,
wear safety belts properly and lock the
doors whenever you drive.
Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.There are several ways to lock and unlock your vehicle.
You can use the remote keyless entry system.
You can use your key to unlock your door from
the outside.
You can lock or unlock the door from the inside by sliding
the manual lever forward or rearward. When the door is
unlocked, you can see a red area on the lever.
The manual lever on each door works only
that door’s lock.
