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 or LATCH
system parts?
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 the LATCH system was being used during a more
severe crash, you may need new LATCH system parts.
If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have LATCH
system, safety belt, or seat parts repaired or replaced.
New parts and repairs may be necessary even if the belt
or LATCH system wasn't being used at the time of
the collision.
If an air bag in¯ates, you'll need to replace air bag
system parts. See the part on the air bag system earlier
in this section.

Section 2 Features and Controls

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.
2-2

This vehicle has one
double-sided key for the
ignition and door locks.
It will ®t with either side up.
When a new vehicle is delivered, the dealer
provides the owner with a pair of identical keys and a
bar-coded tag.
The bar-coded tag has a code on it that tells your
dealer or a quali®ed locksmith how to make extra keys.
Keep this tag in a safe place. If you lose your keys,
you'll be able to have new ones made easily using
this tag.
Notice:Your vehicle has a number of features
that can help prevent theft. 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
spare keys.If you ever do get locked out of your vehicle, call GM
Roadside Assistance Center. See
Roadside Assistance
Program on page 7-5.

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 interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
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.
Changes or modi®cations to this system by other than
an authorized service facility could void authorization to
use this equipment.
2-3

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 or
resynchronization is necessary. See ªBattery
Replacementº and ªResynchronizationº under
ªRemote Keyless Entry System Operationº following
this section.
·If you are still having trouble, see your dealer or a
quali®ed technician for service.
Remote Keyless Entry System
Operation
Your vehicle may have this feature.
Q(Lock):Pressing this button once will lock all of the
doors. The parking lamps will ¯ash and the interior
lamps will turn on brie¯y. Press LOCK again within ®ve
seconds and the parking lamps will ¯ash and the
horn will chirp brie¯y.
2-4

W(Unlock):Pressing this button once will unlock the
driver's door. The parking lamps will ¯ash twice and
the interior lamps will turn on. Press UNLOCK
again within ®ve seconds to unlock the remaining doors.
The parking lamps will ¯ash.
L(Panic Alarm):The remote keyless entry transmitter
comes equipped with an instant panic alarm. To use
the alarm, press the horn symbol when the ignition
is turned off. The horn will sound and both the interior
and exterior lamps will ¯ash for up to thirty seconds. To
stop the instant panic alarm, press the panic button
again, wait for thirty seconds, or start the vehicle.
j(Cargo Door):Press this button to unlock the cargo
doors only.
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.
Resynchronization
Resynchronization may be necessary due to the
security method used by this system. The transmitter
does not send the same signal twice to the receiver. The
receiver will not respond to a signal that has been
sent previously. This prevents anyone from recording
and playing back the signal from the transmitter.
To resynchronize your transmitter, stand close to your
vehicle and press and hold the LOCK and UNLOCK
buttons on the transmitter at the same time for seven
seconds. The door locks should cycle to con®rm
synchronization. If the locks do not cycle, see your
dealer for service.
2-5

Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about four years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it's probably time to change the battery.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.
To replace the battery in the keyless entry transmitter,
do the following:
1. Use an object like a coin to pry open the transmitter.
2. Once the transmitter is separated, use an object
like a pencil to remove the old battery. Do not use
a metal object.
3. Remove and replace the battery, positive (+)
side down.
4. Snap the transmitter back together tightly to be sure
no moisture can enter.
5. Press and hold LOCK and UNLOCK on the remote
keyless entry transmitter for seven seconds to
resynchronize the transmitter.
6. Check the operation of the transmitter.
2-6

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
·Passengers Ð especially children Ð 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, see
Remote Keyless Entry System on page 2-3for more
information.
From the outside, use your key.
To lock the door from
the inside, slide the
manual lever on your door
down. To unlock the
door, slide the manual
lever up.
2-7

Power Door Locks
Press the bottom side of the power door lock switch to
lock all the doors at once. Press the top side of the
power door lock switch to unlock all the doors at once.
When a door is locked, the inside door handle will
not work.
Cargo Door Relocking
This feature protects the owner from having an
unsecured side cargo door. If the side cargo door is
open when the lock button is pressed on the door or the
remote keyless entry transmitter, all doors will lock
and then re-lock again after the cargo door is closed. If
the cargo door is not closed within several minutes,
the re-lock will not occur.
Rear Door Security Locks
Security locks are located on the passenger side rear
door, the side sliding door or the front portion of
the 60/40 side swing-out door.
