If a door is opened without the key or the remote keyless
entry transmitter, the alarm will go off. The headlamps
and parking lamps will flash for two minutes, and the
horn will sound for 30 seconds, then will turn off to
save the battery power.
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.
Here’s how to avoid setting off the alarm by accident:
If you don’t want to activate the theft
system, the vehicle should be locked with the door
the doors are closed.
Always unlock a door with a key, or use the remote
keyless entry transmitter. Unlocking a door any other
way will set off the alarm.
If you set off the alarm by accident, unlock any
door with the key. You can also turn off the alarm by
pressing unlock on the remote keyless entry transmitter.
The alarm won’t stop if you try to unlock a door any
Testing the Alarm
The alarm can be tested by following these steps:
From inside the vehicle, lower the driver’s window
and open the driver’s door.
Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
Get out of the vehicle, close the door and wait for
the SECURITY light to go out.
Then reach in through the window, unlock the
door with the manual door lock and open the door.
This should set off the alarm.
When the alarm is set the power door unlock switch is
If the alarm does not sound when it should but the
headlamps flash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse,
see “Fuses and Circuit Breakers” in the Index.
If the alarm does not sound or the headlamps do not
flash, the vehicle should be serviced by your dealer.
Your vehicle is equipped with the Passlock
Passlock is a passive theft
deterrent system. Passlock
enables fuel if the ignition lock cylinder is turned with
a valid key. If a correct key is not used or the ignition
lock cylinder is tampered with, fuel is disabled and the
vehicle will not start.
During normal operation, the SECURITY light will
go off approximately five seconds after the key is
turned to RUN.
If the engine stalls and the SECURITY light flashes,
wait about 10 minutes until the light stops flashing
before trying to restart the engine. Remember to release
the key from START as soon as the engine starts.
If the engine does not start after three tries, the vehicle
If the engine is running and the SECURITY light
comes on, you will be able to restart the engine if you
turn the engine off. However, your Passlock system
is not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock at this
time. You may also want to check the fuse (see “Fuses
and Circuit Breakers” in the Index). See your dealer
In an emergency, call the GM Roadside Assistance
Center. See “Roadside Assistance” in the Index.
Turn and Lane Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow
you to signal a turn or a lane change.
To signal a turn, move the lever all the way up
or down. When the turn is finished, the lever will
An arrow on the instrument
panel cluster will flash in
the direction of the turn or
To signal a lane change, just raise or lower the lever
until the arrow starts to flash. Hold it there until you
complete your lane change. The lever will return by
itself when you release it. When signaling a lane
change a light will flash on the bottom of the driver’s
or passenger’s outside rearview mirror.
As you signal a turn or a lane change, if the arrows flash
more quickly than normal, a signal bulb may be burned
out and other drivers won’t see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows don’t go on at all when you
signal a turn, check the fuse (see “Fuses and Circuit
Breakers” in the Index) and for burned
If you have a trailer towing option with added wiring for
the trailer lamps, a different turn signal flasher is used.
With this flasher installed, the signal indicator will flash
even if a turn signal bulb is burned out. Check the front
and rear turn signal lamps regularly to make sure they
Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime will sound at each flash of the turn
signal. To turn off the chime, move the turn signal lever
to the center.
Press and release the switch to turn the inflator off.
Place the inflator kit tools in the pouch and store it
properly. Remove the inflator hose from the outlet
during loading and unloading. Load leveling will not
function with the inflator hose attached to the inflator
outlet. See “Electronically Controlled Air Suspension
System” in the Index.
To reinstall the cover, line up the tabs at the back of
the cover, put it in place and latch the tabs.
A continuous flashing indicator light may also
indicate a malfunction in the air suspension system.
See “Electronically Controlled Air Suspension System”
in the Index.
Inflating something too much can make it explode,
and you or others could be injured. Be sure to read
the inflator instructions, and inflate any object
only to its recommended pressure.
Accessory Power Outlets
With the accessory power outlets, you can plug in
auxiliary electrical equipment such as a cellular
telephone or CB radio.
Your vehicle has three accessory power outlets.
The first outlet is located to the right of the cigarette
lighter on the instrument panel. The second outlet is
located on the rear of the center console, and the third
one is located in the rear of the vehicle near the liftgate.
Remove the cover from the outlet to use the outlet.
Be sure to put the cover back on when not using the
accessory power outlet.
Certain electrical accessories may not be compatible
with the accessory power outlet and could result in
blown vehicle or adaptor fuses. If you experience a
problem, see your dealer for additional information
on the accessory power outlets.
Adding some electrical equipment to your vehicle
can damage it or keep other things from working
as they should. This wouldn’t be covered by your
warranty. Check with your dealer before adding
electrical equipment, and never use anything that
exceeds the fuse rating.
When adding electrical equipment, be sure to follow
the proper installation instructions included with
Power outlets are designed for accessory plugs
only. Do not hang any type of accessory or
accessory bracket from the plug. Improper use
of the power outlet can cause damage not covered
by your warranty.

engine oil level right away. For more information,
see “Check Oil Level Message” in the Index.
You should check your engine oil level regularly;
this is an added reminder.
Checking Engine Oil
It’s a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.

The headlamp wiring is protected by four fuses.
An electrical overload will cause a lamp to go on and
off. If this happens, have your headlamp wiring checked
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow or ice, the wiper will stop until the motor cools.
If the overload is caused by some electrical problem,
be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers protect the power windows and other
power accessories. When the current load is too heavy,
the circuit breaker opens and closes, protecting the
circuit until the problem is fixed or goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of fires
caused by electrical problems.
Look at the silver
colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical size
If you ever have a problem on the road and don’t have
a spare fuse, you can borrow one that has the same
amperage. Just pick some feature of your vehicle that
you can get along without
like the radio or cigarette
and use its fuse, if it is the correct amperage.
Replace it as soon as you can.
Engine Compartment Fuse Block
The fuse block is located under the hood in the
engine compartment on the driver’s side of the vehicle.
