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, seeOlder Children on page 1-30orInfants and
Young Children on page 1-33. Follow those rules for
everyone’s protection.
First, you will want to know which restraint systems your
vehicle has.
We will start with the driver position.
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.
Be sure to use the correct buckle when buckling
your lap-shoulder belt. If you nd that the latch plate
will not go fully into the buckle, see if you are
using the buckle for the center passenger position.
1-16

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 the belt is out of
the way. If you slam the door on it, you can damage
both the belt and your vehicle.
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. Incorrect positioning of the shoulder belt can
reduce the effectiveness of the safety belt.
To move it down, press
the release button (A) and
move the height adjuster
to the desired position.
You can move the
height adjuster up just
by pushing up on the
shoulder belt guide.
After you move the height adjuster to where you want it,
try to move it down without pressing the release
button to make sure it has locked into position.
1-22

The roof-mounted side impact airbag for the right front
passenger and the person seated directly behind
that passenger is in the ceiling above the side windows.
{CAUTION:
If something is between an occupant and an
airbag, the airbag 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. Never secure anything to the
roof of your vehicle by routing the rope or
tie-down through any door or window opening.
If you do, the path of an inating airbag will be
blocked. Do not let seat covers block the
ination path of a side impact airbag. The path
of an inating airbag must be kept clear.
1-58

What Will You See After an
Airbag Inates?
After the airbags inate, they quickly deate, so quickly
that some people may not even realize the airbags
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, the side of the
seatback closest to the door for seat-mounted side
impact airbags, and the area along the ceiling of your
vehicle near the side windows for roof-mounted side
impact airbags — may 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 out of the
windshield 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 cannot
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 may 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. The hazard warning
ashers will also come on when the airbags deploy. If you
want to turn them off, press the hazard warning asher
button twice.

One key is used for the
ignition, the driver’s door
and the glovebox lock.
When a new vehicle is delivered, the dealer removes
the key tag from the key and gives it to the rst owner.
Each tag has a code on it that tells your dealer or a
qualied locksmith how to make extra keys. Keep the
tag in a safe place. If you lose your key, you will be able
to have a new one made easily using the tag.If you need a new key, contact your dealer who can
obtain the correct key code. SeeRoadside Assistance
Program on page 7-6for more information.
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 your vehicle has the OnStar
®system with an active
subscription and you lock your keys inside the vehicle,
OnStar
®may be able to send a command to unlock
your vehicle. SeeOnStar®System on page 2-38
for more information.

Remote Keyless Entry System
Operation
The vehicle’s doors can be locked and unlocked, and
the trunk can be unlatched from about 3 feet (1 m) up to
60 feet (18 m) away with the remote keyless entry
transmitter.
If your vehicle has the remote start feature you can also
start your vehicle with the remote keyless entry
transmitter. Your remote keyless entry transmitter, with
the remote start button, provides an increased range
of 195 feet (60 m) away. However, the range may
be less while the vehicle is running. As a result, you
may need to be closer to your vehicle to turn it off than
you were to turn it on.
There are other conditions which can affect the
performance of the transmitter. SeeRemote Keyless
Entry System on page 2-5.The following functions may be available if your vehicle
has the remote keyless entry system:
/(Remote Vehicle Start):If your vehicle has this
feature, it may be started from outside the vehicle using
the remote keyless entry transmitter. See “Remote
Vehicle Start” following for more detailed information.Remote Keyless Entry
