Section 2 Features and Controls

Keys
{CAUTION:
Leaving children in a vehicle with the ignition
key is dangerous for many reasons. They
could operate the power windows or other
controls or even make the vehicle move. The
children or others could be badly injured or
even killed. Do not 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 qualied 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: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 GM
Roadside Assistance Center. SeeRoadside Assistance

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 “Battery
Replacement” and “Resynchronization” under
“Remote Keyless Entry System Operation” following
this section.
If you are still having trouble, see your dealer or a
qualied technician for service.
Remote Keyless Entry System
Operation
Your vehicle may have this feature.
Q(Lock):Press this
button once to lock all of
the doors. The parking
lamps will ash and
the interior lamps will turn
on briey. Press the
lock button again within ve
seconds and the parking
lamps will ash and
the horn will chirp briey.
W(Unlock):Press this button once to unlock the

2-4

L(Panic Alarm):The remote keyless entry transmitter
comes equipped with an instant panic alarm. To use
the alarm, press the horn symbol while 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 conrm
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 the lock and unlock buttons on the
remote keyless entry transmitter for seven seconds
to resynchronize the transmitter.
6. Check the operation of the transmitter.

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.
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.

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.
