The system can only be activated using the
remote keyless entry transmitter, or by OnStar®.
SeeOnStar®System on page 129for additional
information. You should also remember that
you can start your vehicle with the correct key if
the alarm has been set off.
Here is how to avoid setting off the alarm by
accident:
If you do not want to arm the theft-deterrent
system, the vehicle should be locked with
the manual door lock lever, the power
door lock switch, or the key, after the doors
are closed.
If the content theft-deterrent system is armed,
unlock the doors by pressing the unlock
button on the remote keyless entry transmitter
or by OnStar
®. Unlocking a door any other
way will activate the alarm.
If you set off the alarm by accident, you can turn it
off by pressing unlock on the remote keyless
entry transmitter, starting the vehicle with
the correct key, or by having OnStar
®unlock the
doors. The alarm will not stop if you try to
unlock a door any other way.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, activate the system
by locking the doors with the remote keyless
entry transmitter.
2. Unlock the door with the manual door lock
and open the door. This should set off the
pre-alarm. Wait 10 seconds for the full alarm
to activate.
3. To turn the alarm off, press the unlock button
on the remote keyless entry transmitter or
start the engine.
If the alarm does not sound when it should but the
lights ash, check to see if the horn works. The
horn fuse may be blown. To replace the fuse, see
Fuses and Circuit Breakers on page 417.
If the alarm does not sound or the front turn signal
lamps do not ash, see your dealer for service.

Engine Coolant Heater
Your vehicle may have this feature.
In very cold weather, 0°F (–18°C) or colder, the
engine coolant heater can help. You will get easier
starting and better fuel economy during engine
warm-up. Usually, the coolant heater should be
plugged in a minimum of four hours prior to starting
your vehicle. At temperatures above 32°F (0°C),
use of the coolant heater is not required. Your
vehicle may also have an internal thermostat in the
plug end of the cord. This will prevent operation of
the engine coolant heater when the temperature is
at or above 0F (−18C) as noted on the cord.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located in the engine compartment
behind the underhood fuse block on the
driver’s side of the vehicle.
3. Plug it into a normal, grounded 110-volt
AC outlet.
{CAUTION:
Plugging the cord into an ungrounded
outlet could cause an electrical shock.
Also, the wrong kind of extension cord
could overheat and cause a re. You could
be seriously injured. Plug the cord into a
properly grounded three-prong 110-volt AC
outlet. If the cord will not reach, use a
heavy-duty three-prong extension cord
rated for at least 15 amps.
4. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it
away from moving engine parts. If you do not, it
could be damaged.
How long should you keep the coolant heater
plugged in? The answer depends on the outside
temperature, the kind of oil you have, and some
other things. Instead of trying to list everything here,
we ask that you contact your dealer in the area
where you will be parking your vehicle. The dealer
can give you the best advice for that particular area.

Turn and Lane-Change Signals
The turn signal has one upward (for right) and
one 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 nished, the lever will
automatically return to the off position.
To signal a lane change, raise or lower the lever
until the arrow starts to ash. Hold it there until
the change is completed. The lever will return by
itself when released.
An arrow on the
instrument panel
cluster will ash in
the direction of the
turn or lane change.
As you signal a turn or a lane change, if the
arrows ash more quickly than normal, a signal
bulb may be burned out and other drivers will
not see your vehicle’s turn signal.If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when
signaling a turn, check for a burned-out bulb or a
blown fuse. For bulb replacement, seeTaillamps,
Turn Signal, Stoplamps and Back-up Lamps
on page 363. For a blown fuse or circuit breaker,
seeFuses and Circuit Breakers on page 417
Turn Signal On Chime
If a turn signal is left on for more than 3/4 of a
mile (1.2 km), a chime will sound at each ash of
the turn signal and the message TURN SIGNAL
will also appear in the DIC. To turn the chime and
message off, move the turn signal lever to the
off position.
See “TURN SIGNAL” underDIC Warnings and
Messages on page 196DIC Warnings and
Messages for more information.

Battery Run-Down Protection
This feature shuts off the dome lamp if it is left
on for more than 20 minutes when the ignition
is in LOCK. This will help prevent your battery
from running down.
Accessory Power Outlet(s)
Your vehicle has accessory power outlets.
With accessory power outlets you can plug in
auxiliary electrical equipment such as a cellular
telephone or CB radio.
Your vehicle has two accessory power outlets
located on the lower part of the instrument panel
below the climate control system and there
may be one located in the rear cargo area.
A small cap must be pulled down to access an
accessory power outlet. When not using an outlet,
be sure to cover it with the protective cap.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always
unplug electrical equipment when not in use
and do not plug in equipment that exceeds the
maximum amperage rating of 20 amperes.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. Do not use equipment exceeding
maximum amperage rating of 20 amperes.
Check with your dealer before adding electrical
equipment.
When adding electrical equipment, be sure to
follow the proper installation instructions included
with the equipment.
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.

Ashtray(s) and Cigarette Lighter
Your vehicle may have an ashtray and cigarette
lighter.
Your ashtray is located in your center console
area. The ashtray can be removed for cleaning.
When the ashtray is removed, this area can
also be used as a cupholder.
Notice:If you put papers, pins, or other
ammable items in the ashtray, hot cigarettes
or other smoking materials could ignite
them and possibly damage your vehicle.
Never put ammable items in the ashtray.
To use the lighter, press it in all the way, and let
go. When it’s ready, it will pop back out by itself.
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.
Climate Controls
Climate Control System

Environmental Concerns
Off-road driving can provide wholesome and
satisfying recreation. However, it also raises
environmental concerns. We recognize these
concerns and urge every off-roader to follow
these basic rules for protecting the environment:
Always use established trails, roads, and
areas that have been specially set aside
for public off-road recreational driving; obey
all posted regulations.
Avoid any driving practice that could damage
the environment — shrubs, owers, trees,
grasses — or disturb wildlife. This includes
wheel-spinning, breaking down trees, or
unnecessary driving through streams or over
soft ground.
Always carry a litter bag — make sure all
refuse is removed from any campsite
before leaving.
Take extreme care with open res (where
permitted), camp stoves, and lanterns.
Never park your vehicle over dry grass or
other combustible materials that could
catch re from the heat of the vehicle’s
exhaust system.
Traveling to Remote Areas
It makes sense to plan your trip, especially when
going to a remote area. Know the terrain and
plan your route. You are much less likely to
get bad surprises. Get accurate maps of trails
and terrain. Try to learn of any blocked or
closed roads.
It is also a good idea to travel with at least one
other vehicle. If something happens to one
of them, the other can help quickly.
Does your vehicle have a winch? If so, be sure
to read the winch instructions. In a remote area,
a winch can be handy if you get stuck. But you
will want to know how to use it properly.
