Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver’s window
and open the driver’s door.
2. 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.
3. Get out of the vehicle, close the door and wait for
the security light to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door. This
should set off the alarm.
While the alarm is set, the power door unlock switch is
not operational.
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 on page 5-109
.
If the alarm does not sound or the headlamps do not
flash, the vehicle should be serviced by your dealer.
Passlock
®
Your vehicle is equipped with the Passlock
®
theft-deterrent system.
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, the fuel system is
disabled and the vehicle will not start.
During normal operation, the security light will turn 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
needs service.
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 on page 5-109
. See your
dealer for service.
In an emergency, call the Roadside Assistance Center.
See
Roadside Service on page 7-6
.

Accessory Power Outlets
With accessory power outlets you can plug in auxiliary
electrical equipment such as a cellular telephone or
CB radio.
Your vehicle is equipped with many accessory power
outlets.
One outlet is located in the center console. Press the
button on the side of the console door to access
the outlet.
There may also be accessory power outlets located on
the back of the center console above the cupholder
and in the rear cargo area on the passenger side.
Do not try to put the cigarette lighter in any of the
accessory 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.
Certain power accessory plugs may not be compatible
with the accessory power outlets and could result in
blown vehicle or adapter fuses. If you experience
a problem, see your dealer for additional information on
the accessory power plugs.
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.
Analog Clock
To adjust the clock, do the following:
1. Locate the adjustment button to the lower left
corner of the clock.
2. Push and hold the adjustment button to spin the
clock hands. Release the button
before
you get to
the desired time.
3. Push and release the button to increase the time by
one minute increments until the desired time is
reached.
3-21
REAR ACCESS OPEN
If the liftgate is open while the ignition is in RUN, this
message will appear on the DIC and you will hear
a chime. Turn off the vehicle and check the liftgate.
Restart the vehicle and check for the message on the
DIC display. Pressing the select button will clear it
from the DIC display.
REPLACE LIFTGATE FUSE
This message will be displayed if the liftgate lock
malfunctions and/or the liftgate fuse blows. For more
information on fuses, see
Fuses and Circuit Breakers on
page 5-109
.
If the message returns after replacing the fuse, see your
dealer for service.
KEYFOB X BATTERY LOW
If a remote keyless entry transmitter battery is low, this
message will appear on the DIC. The battery needs
to be replaced in the transmitter. Pressing the select
button will clear it from the DIC display.
TRACTION ACTIVE
When the traction control system has detected that any
of the vehicle’s wheels are slipping, the traction
control system will activate and this message will appear
on the DIC. See
Stabilitrak
®
System on page 4-9
for
more information.
TRACTION SYS LIMITED
If the brake traction-control activates constantly or if the
brakes have heated up due to high-speed braking,
brake traction-control will be disabled and the
TRACTION SYS LIMITED message will be displayed.
For more information on the Stabilitrak system and
traction contorl, see
Stabilitrak
®
System on page 4-9.
STABILITY SYS ACTIVE
You may see the STABILITY SYS ACTIVE message on
the DIC. It means that an advanced computer-controlled
system has come on to help your vehicle continue to go in
the direction in which you’re steering. Stabilitrak
®
activates
when the computer senses that your vehicle is just
starting to spin, as it might if you hit a patch of ice or other
slippery spot on the road. When the system activates,
you may hear a noise or feel a vibration in the brake pedal.
This is normal. When the STABILITY SYS ACTIVE
message is on, you should continue to steer in the direction
you want to go. The system is designed to help you in
bad weather or other difficult driving situations by making
the most of whatever road conditions will permit.

Engine Oil
If the CHECK OIL LEVEL message appears on the
instrument cluster, it means you need to check
your engine oil level right away.
For more information, see “CHECK OIL LEVEL” under
DIC Warnings and Messages on page 3-57
.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It is 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 engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-10
for
the location of the engine oil dipstick.
Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don’t, the oil
dipstick might not show the actual level.
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
5-11
Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
circuit breaker and a fuse. If the motor overheats due to
heavy snow, etc., the wiper will stop until the motor
cools. If the overload is caused by some electrical
problem and not snow, etc., 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, circuit breakers
and fusible thermal links. 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 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 lighter – and use its fuse, if it is the correct
amperage. Replace it as soon as you can.
5-109
Instrument Panel Fuse Block
The fuse block access
door is on the driver’s side
edge of the instrument
panel. Pull off the cover to
access the fuse block.
To remove fuses if you don’t have a fuse extractor, hold
the end of the fuse between your thumb and index
finger and pull straight out.
You may have spare fuses located behind the fuse
block access door. These can be used to replace a bad
fuse. However, make sure it is of the correct amperage.
