This vehicle has one
double-sided key for the
ignition and door lock.
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 key
code number.
The key code number tells your dealer or a quali®ed
locksmith how to make extra keys. Keep this number in
a safe place. If you lose your keys, you'll be able to
have new ones made easily using this number.
Your selling dealer should also have this number.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
žsystem 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 2-39for more information.

Remote Keyless Entry System
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 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.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
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.
K(Unlock):Press unlock
for the driver's door to
unlock automatically, the
parking lamps to ¯ash
and the interior lights to go
on. Press the unlock
button a second time within
three seconds to unlock
all the doors.
You can program different feedback settings through the
Driver Information Center (DIC). For more information
see
Driver Information Center (DIC) on page 3-50.
Q(Lock):Press lock to lock all the doors. Press lock
again within three seconds and the horn will chirp.
L(Panic):Press the horn symbol to make the horn
sound. The headlamps and taillamps will ¯ash for up to
30 seconds. This can be turned off by pressing the
horn button again, by waiting for 30 seconds, or
by 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.
2-6

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.
The Driver Information Center (DIC) will display a
RFA # BATTERY LOW message when the transmitter
battery is low.
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 remote keyless entry
transmitter do the following:
1. Insert a thin coin in the slot between the covers
of the transmitter housing. Gently pry the
transmitter apart.
2. Remove and replace the battery with a three-volt
CR2032 or equivalent battery, positive (+) side
down.
3. Align the covers and snap them together.
4. Check the operation of the transmitter.

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.
You can use the remote keyless entry system.
You can use your key to unlock your door from the
outside.
You can lock or unlock the door from the inside by
sliding the manual lever forward or rearward. When the
door is unlocked, you can see a red area on the lever.
The manual lever on each door works only that
door's lock.

Power Door Locks
The power door lock
switches are located on
the driver's and front
passenger's armrests.
Remove the ignition key and press the lock symbol to
lock all of the doors at once. To unlock the doors, press
the other side of the switch.
Delayed Locking
This feature makes it easier to use the power door locks
to lock all the doors and the liftgate when leaving your
vehicle.
The ®rst time you attempt to lock the doors using the
power lock switch or the remote keyless entry
transmitter, with a door or the liftgate open, three
chimes will signal that delayed locking is being used. All
doors and the liftgate can be reopened for up to ®ve
seconds from the time the last door is closed.Five seconds after the last door is closed, all the doors
will lock. You can lock the doors immediately by
using the power door lock switch or by pressing the lock
button on the optional remote keyless entry transmitter
a second time.
If the key is inserted in the ignition, this feature will not
lock the doors. The lockout prevention feature will
operate instead.
You can enable or disable the delayed locking feature.
If the feature is disabled, the doors will lock immediately
when a power door lock switch or remote keyless
entry transmitter lock button is pressed.
Programming Delayed Locking
When your vehicle was shipped from the factory, the
delayed locking feature was programmed on, or
enabled. The mode may have been changed since it
left the factory. To turn the delayed locking feature on or
off, do the following:
1. Press and hold the power door lock switch on the
driver's door in the lock position.
2. Press the remote keyless entry transmitter unlock
button twice.
If the delayed locking feature was on, it will now be off.
If the feature was off, it will now be on.
