Section 2 Features and Controls
2-1

Your vehicle has one
double-sided key for the
ignition and all door
locks as well as the spare
tire hoist lock, if equipped.
If you ever lose your keys, your dealer will be able to
assist you with obtaining replacements.
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 the
GM Roadside Assistance Center. See
Roadside
Assistance Program on page 7-6. If your vehicle is
equipped with the OnStaržsystem with an active
subscription and you lock your keys inside the vehicle,
OnStar
žmay be able to send a command to unlock
your vehicle. SeeOnStaržSystem on page 2-55for more information.
Remote Keyless Entry System
If equipped, the 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 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.
2-4

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 ªBattery Replacementº under
Remote Keyless Entry System Operation on
page 2-5.
·If you are still having trouble, see your dealer or a
quali®ed technician for service.
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.
UNLOCK:Pressing this button once will unlock the
driver's door. The parking lamps will ¯ash and the
interior lights will come on. The ground illumination
lamps will come on. Pressing UNLOCK again within
three seconds will cause the remaining doors to unlock.
The parking lamps will ¯ash and the interior lights will
come on.
LOCK:Pressing this button once will lock all of the
doors. Wait one second, then press LOCK again and the
horn will chirp.
Operating the keyless entry transmitter may interact with
the theft-deterrent system. See
Content Theft-Deterrent
on page 2-18.
2-5

Remote Alarm
When the panic button with the horn symbol on the
keyless entry transmitter is pressed, the horn will sound
and the headlamps and taillamps will ¯ash for up to
30 seconds. This can be turned off by pressing the panic
button again, waiting for 30 seconds, or 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.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two 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.
2-6

To replace the battery in the keyless entry transmitter
do the following:
1. Insert a dime, or similar object, in the slot between
the covers of the transmitter housing near the key
ring hole. Remove the bottom by twisting the dime.
2. Remove and replace the battery with a three-volt
CR2032 or equivalent battery, positive (+) side up.
3. Align the covers and snap them together.
4. Resynchronize the transmitter.
5. Check the operation of the transmitter.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 15
seconds. The door locks should cycle to con®rm
synchronization. If the locks do not cycle, see your
dealer for service.

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 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 keyless entry system (if equipped).
You can also use your key.

lock/unlock feature which enables you to program your
vehicle's power door locks. You can program this
feature through the Driver Information Center (DIC), or
by the following method.
Programmable Locking Feature
The following is the list of available programming options:
Mode 1:All doors lock when the transmission is shifted
into gear. This is the mode that is pre-programmed
in the factory for your vehicle for automatic transmission
vehicles.
Mode 2:All doors lock when the vehicle speed is
greater than 8 mph (13 km/h). This is the mode that is
pre-programmed in the factory for manual transmission
vehicles.
Mode 3:No automatic door locking.
2-10

The following instructions tell you how to change the
automatic door lock mode. Choose one of the three
programming options listed above before entering the
program mode. To enter the program mode, do the
following:
1. Begin with the ignition off. Then pull the turn
signal/multifunction lever toward you and hold
it there while you perform the next step.
2. Turn the key to RUN then back to LOCK twice.
Then, with the key in LOCK, release the turn
signal/multifunction lever. Once you do this, the
doors will lock and unlock, the horn will chirp twice,
and a 30-second timer will begin. You are now
ready to program the automatic door lock feature.

two, or three chimes. The number of chimes tells
you which lock mode is currently selected. Continue
to press the door lock switch until the number of
chimes that you hear matches the number of
the mode that you want. If you take longer than 30
seconds, the locks will automatically lock and
unlock and the horn will chirp twice to indicate that
you have left the program mode. If this occurs,
you can repeat the procedure beginning with Step 1
to re-enter the programming mode.You can exit the program mode any time by turning the
ignition to RUN (the doors will automatically lock and
unlock and the horn will chirp twice to indicate that you
are leaving the program mode). If the lock/unlock
switches are not pressed while in the programming mode,
the current automatic settings will not be modi®ed.
See your dealer for more information.
