Testing the Alarm
1. From inside the vehicle, roll down the window,
then get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open,
lock the vehicle using the power door lock switch
or the remote keyless entry transmitter and
close the door. Wait approximately 30 seconds until
the security light goes off.
3. Reach in and unlock the door using the manual
lock and open the door. The horn will sound and
the exterior lamps will flash.
You can turn off the alarm by unlocking the driver’s door
with your key, using the unlock button on the remote
keyless entry transmitter or by starting the car with
a valid key.
If the alarm does not sound when it should, check to
see if the horn works. The horn fuse may be blown.
To replace the fuse, see
Fuses and Circuit Breakers on
page 5-94
. If the fuse does not need to be replaced, you
may need to have your vehicle serviced.
To reduce the possibility of theft, always arm the
theft-deterrent system when leaving your vehicle.

2-19
Immobilizer Operation
Your vehicle is equipped
with a passive
theft-deterrent system.
The system works when you turn the key to ON.
The key uses a transponder that matches an immobilizer
control unit in your vehicle. The correct key will start
the vehicle.
Your vehicle has a special key that works with the
theft-deterrent system. There is a transponder in the key
head. If the key is ever damaged, you may not be
able to start your vehicle.
When trying to start the vehicle, if the engine does not
start and the security light comes on, the key may
have a damaged transponder. Turn the ignition off and
try again.
If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time,
you may also want to check the fuse. See
Fuses
and Circuit Breakers on page 5-94
. If the engine still
does not start with the other key, your vehicle needs
service. If your vehicle does start, the first key may be
faulty. See your dealer who can service the
theft-deterrent system to have a new key made.
It is possible for the theft-deterrent system decoder to
learn the transponder value of a new or replacement
key. Up to 10 additional keys may be programmed for
the vehicle. This procedure is for learning additional
keys only.
Canadian Owners:
If you lose or damage your keys,
only a GM dealer can service the theft-deterrent system
to have new keys made. To program additional keys you
will require two current driver’s keys. You must add a step
to the following procedure. After Step 2, repeat Steps 1
and 2 with the second current driver’s key. Then continue
with Step 3.
2-20
Turn and Lane-Change Signals
To signal a turn, move the lever all the way up or
down. The lever returns automatically when the turn is
complete.
An arrow on the instrument
panel cluster will flash in
the direction of the
turn or lane change.
Raise or lower the lever until the arrow starts to flash
to signal a lane change. Hold it there until the lane
change is complete. The lever returns to its original
position when it’s released.
Arrows that flash rapidly when signaling for a turn or
lane change may be caused by a burned-out signal bulb.
Other driver’s won’t see the signal.
Replace burned-out bulbs to help avoid possible
accidents. Check the fuse and for burned-out bulbs if
the arrow fails to work when signaling a turn. See
Fuses
and Circuit Breakers on page 5-94
for more information.
Turn Signal On Chime
If the turn signal is left on for about 1 mile (1.6 km),
a warning chime will sound and the Turn Signal
On message will appear on the Driver Information
Center (DIC) display. See “Turn Signal On Message”
under
DIC Warnings and Messages on page 3-61
for more information.
Headlamp High/Low-Beam Changer
Push forward on the turn signal/multifunction lever to
change the headlamps from low to high beam.
Pull the lever back and then release it to change from
high to low beam.
This light on the instrument
panel cluster will be on,
indicating high-beam
usage.

Accessory Power Outlets
With accessory power outlets, you can plug in auxiliary
electrical equipment such as a cellular telephone or
CB radio.
The front accessory power outlet is located in the
ashtray on the instrument panel below the climate
control system. The outlet will have a cigarette lighter
if your vehicle has this option. Remove the cigarette
lighter to access the outlet.
The rear accessory power outlet is located on the back
of the center console.
Your vehicle may have a small cap that must be
removed to access the accessory power outlet. If it
does, when not using the outlet be sure to cover it with
the protective cap.
The accessory power outlet will only operate when the
ignition is in ACCESSORY or ON and for 10 minutes
after turning the ignition to OFF. If you would like
the accessory power outlet to operate regardless of
ignition position, and for extended periods of time,
you can do the following:
1. Open the hood and locate the underhood fuse block.
2. Find the I/P OUTLET and OUTLET fuses and
move them over a space, to the open cavity
next to each fuse.
Notice:
Leaving electrical equipment on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.
Certain electrical accessories may not be compatible
with the accessory power outlet and could result
in blown vehicle or adapter fuses. If you experience a
problem see your dealer for additional information
on accessory power outlets.
Notice:
Adding any electrical equipment to your
vehicle may damage it or keep other components
from working as they should. The repairs would not
be covered by your warranty. Check with your
dealer before adding electrical equipment.
When adding electrical equipment, be sure to follow the
proper installation instructions included with the
electrical equipment you install.
Notice:
Improper use of the power outlet can cause
damage not covered by your warranty. Do not
hang any type of accessory or accessory bracket
from the plug because the power outlets are
designed for accessory power plugs only.
3-24
Ashtrays and Cigarette Lighter
Your vehicle may have an ashtray and cigarette lighter.
Notice:
If you put papers or other flammable
items in the ashtray, hot cigarettes or other smoking
materials could ignite them and possibly damage
your vehicle. Never put flammable items in the
ashtray.
Ashtray
The ashtray is located under the climate control panel
on the center console. Press on the door to release the
ashtray.
To empty the ashtray, remove it from the center
console by gripping the edges and pulling straight out.
To reinstall, push the tray back into place.
Cigarette Lighter
Notice:
Holding a cigarette lighter in while it is
heating will not allow the lighter to back away from
the heating element when it is hot. Damage from
overheating may occur to the lighter or heating
element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating.
The cigarette lighter is located next to the ashtray.
The vehicle does not have any cigarette lighters for the
rear seat passengers.
Press the lighter all the way in and release it. It will pop
back out by itself once the element has heated for use.
Cigarette lighters can be used to provide power to
accessories. See
Accessory Power Outlets on
page 3-24
for more information.

Battery
Your new vehicle comes with a maintenance free
ACDelco
®
battery. When it is time for a new battery,
get one that has the replacement number shown on the
original battery’s label. We recommend an ACDelco
®
battery. See
Engine Compartment Overview on
page 5-12
for battery location.
Warning:
Battery posts, terminals and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.
{
CAUTION:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
are not careful. See
Jump Starting on page 5-45
for tips on working around a battery without
getting hurt.
After a power loss, such as disconnecting the battery or
removing the maxi fuses in the power distribution
fuse block, the following steps must be performed to
calibrate the electronic throttle control. If this is not done,
the engine will not run properly.
1. Turn the ignition key to ON. Do not start the engine.
2. Leave the ignition in ON for at least three minutes
so that the electronic throttle control will cycle and
re-learn its home position.
3. Turn the ignition to OFF.
4. Start and run the engine for at least 30 seconds.
Also, for your audio system, see
Theft-Deterrent Feature
on page 3-117
.

Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
circuit breaker. If the wiper motor overheats due to
heavy snow, the wipers will stop until the motor cools
and will then restart.
Power Windows and Other Power
Options
Circuit breakers protect the power windows and power
seats. 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 and rating. If a fuse blows, see your dealer
for service immediately.
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. Pick some feature of your vehicle that
you can get along without – like the radio or cigarette
lighter – and use its fuse, if it is the correct amperage.
Replace it as soon as you can.
The fuses are located in three fuse blocks, one located
in the engine compartment on the passenger’s side
and the other two under the rear seat.
