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'd be less
likely to slide under the lap belt. If you slid under it, the
belt would apply force at your abdomen. This could
cause serious or even fatal injuries. The shoulder belt
should go over the shoulder and across the chest.
These parts of the body are best able to take belt
restraining forces.
The safety belt locks if there's a sudden stop or a crash,
or if you pull the belt very quickly out of the retractor.
Each position next to the windows has a shoulder belt
height adjuster. Move the shoulder belt 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.

1-40
To move it down, push in at the top of the arrows and
move the height adjuster to the desired position. You can
move the adjuster up just by pushing up on the shoulder
belt guide. After you move the adjuster to where you
want it, try to move it down without pushing in to make
sure it has locked into position.
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.

3. Buckle the belt. Make sure the release button is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.4. Pull the rest of the shoulder belt all the way out of
the retractor to set the lock.

5. Pull the rest of the shoulder belt all the way out of
the retractor to set the lock.6. To tighten the belt, feed the shoulder belt back into the
retractor while you push down on the child restraint. If
you're using a forward
-facing child restraint, you may
find it helpful to use your knee to push down on the
child restraint as you tighten the belt.
7. Push and pull the child restraint in different
directions to be sure it is secure.

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.

lever by pulling the lever toward the driver's side of
the vehicle.

double
-sided key for the
ignition and all door locks.
If you ever lose your key, your dealer will be able to
assist you with obtaining a new one.NOTICE:
Your vehicle has a number of new features that
can help prevent theft. But you can have a lot
of trouble getting into your vehicle if you ever
lock your keys inside. You may even have to
damage your vehicle to get in. So be sure you
have extra keys.
If you ever do get locked out of your vehicle, call GM
Roadside Assistance Center. See ªRoadside Assistanceº
in the Index.

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 won't open it. You increase the
chance of being thrown out of the vehicle in
a crash if the doors aren't 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.
If your vehicle is equipped with keyless entry, you can
use your transmitter to lock or unlock your vehicle.
See ªKeyless Entry Systemº later in this section for
more information.
To lock or unlock your door from the outside, use
your key.
To lock your door from the
inside, slide the manual
lever on your door down.
To unlock the door, slide the
manual lever up.

2-8 Power Door Locks (If Equipped)
If your vehicle has power
door locks, press the bottom
side of the power door lock
switch to lock all the doors
at once. To unlock all the
doors at once, press the
top side of the power door
lock switch.
When a door is locked, the inside door handle will
not work.
Keyless Entry System (If Equipped)
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.
Your keyless entry system operates on a radio frequency
subject to Federal Communications Commission (FCC)
Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received,
including interference that may cause undesired
operation.
This device complies with RSS
-210 of Industry Canada.
Operation is subject to the following two conditions:
(1) this device may not cause interference, and (2) this
device must accept any interference received, including
interference that may cause undesired operation of
the device.

2-9
Changes or modifications to this system by other than an
authorized service facility could void authorization to
use this equipment.
At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:

Check the distance. You may be too far from your
vehicle. You may need to stand closer during rainy
or snowy weather.

Check the location. Other vehicles or objects may be
blocking the signal. Take a few steps to the left or
right, hold the transmitter higher, and try again.

Check to determine if battery replacement is
necessary. See the instructions that follow.

If you're still having trouble, see your dealer or a
qualified technician for service.Operation
To unlock the driver's door, press the UNLOCK
button one time. If you press the button again within
five seconds, all of the doors will unlock. When the
UNLOCK button is pressed, the interior dome lamps
are turned on for about 40 seconds or until the ignition
switch is activated. Press the LOCK button to lock
all doors.
