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 7-5. If your vehicle is
equipped with 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. See
OnStap System on page 2-33
for more information.

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 “Battery Replacement” under
Remote Keyless Entry System Operation on
page

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.
To replace the battery in the keyless entry transmitter,
do the following:
1. Insert a thin coin, or similar object, in the slot
between the covers
of the transmitter housing
near the key ring hole. Remove the bottom
by twisting the coin.
CR2032 or equivalent battery, positive
(+) side up.
2. Remove and replace the battery with a three-volt
3. Align the covers and snap them together.
4. Check the operation of the transmitter.

Unlocked doors can be dangerous.

e 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.

at once. Press the recessed side
of the switch with the unlock
symbol, to unlock all the doors at once.
The power door locks will operate at any time even

Sun Visors
To block out glare, you can swing down the top and
bottom visors. You can also swing the bottom visor from
side-to-side. The visors may also have an extension
that can be pulled out for additional glare protection.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make
it
impossible to steal. However, there are ways you
can help.
Content Theft-Deterrent
Your vehicle is equipped with a content theft-deterrent
alarm system.
With this system, the
security light on the cluster
will flash
as you open
the door
(if your ignition is
off), to let you know
that you are activating the
system. This
message reminds you to activate the theft-deterrent
system. Here’s how to do it:
1. Open the door.
2. Lock the door with the power door lock switch or
the remote keyless entry transmitter. The security light should come on and flash.
If you are using the
remote keyless entry transmitter, the door does
not need to be open.
3. Close all of the doors. The light will stop flashing and
stay solid.The security light should go
off after
approximately
30 seconds. The alarm is not armed
until the security light goes
off. If the delayed locking
feature is active, the alarm will not activate until all
doors are closed and the security light goes
off.
Once the system is armed, if a door is opened without
the key or the remote keyless entry transmitter, the
alarm will go
off. Depending on how you have
programmed the alarm in the secondary information
center, the horn may sound, the headlamps may flash
or both the headlamps and the horn will activate.
Remember, the theft-deterrent system won’t activate
if
you lock the doors with a key or use the manual
door lock. It activates only
if you use a power door lock
switch with the door open, or with the remote keyless
entry transmitter. You should also remember that
you can start your vehicle with the correct ignition key
if
the alarm has been set off.
