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 5-97
. 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. 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 5-97
. 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.
2-20
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 5-97
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” under
DIC Warnings
and Messages on page 3-65
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.
Flash-to-Pass
This feature allows you to use the high-beam headlamps
to signal the driver in front of you that you want to pass.
Pull and hold the turn signal/multifunction lever toward
you to use this feature. When you do, the following
will occur:
If the headlamps are off, in low-beam or in Daytime
Running Lamps (DRL) mode, the high-beam
headlamps will turn on. They’ll stay on as long as
you hold the lever there. Release the lever to
turn them off.
If the headlamps are in high-beam mode, they will
switch to low beam. To return to high-beam, push
the lever away from you.
3-10
The power outlets can be set to be powered all of
the time or to turn off 10 minutes after your vehicle is
shut off. If you desire a change from this setting,
see your dealer for a fuse adjustment.
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.
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.
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.

element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating. Do not
use anything other than the cigarette lighter in
the heating element.
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 3-25
for more information.

Battery
Your vehicle has a maintenance free 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
®
replacement
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 5-42
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 3-105
.
Jump Starting
If your battery has run down, you may want to use
another vehicle and some jumper cables to start your
vehicle. Be sure to use the following steps to do it safely.
5-42
4. Open the hoods and locate the positive (+) and
negative (
-
) terminal locations of the other vehicle,
as well as the positive (+) terminal location on
your vehicle’s battery. See
Engine Compartment
Overview on page 5-12
for more information on the
location of the battery.
Your vehicle has a remote negative (
-
) ground
location, as shown in the illustration. It is located
between the battery and the underhood fuse block.
You should always use this remote ground
location, instead of the terminal on the battery.
5-44
Your vehicle has an airbag system. Before attempting to
add anything electrical to your vehicle, see
Servicing
Your Airbag-Equipped Vehicle on page 1-62
.
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.
