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.
When the alarm is set the power door unlock switch is
not operational.
If the alarm does not sound when it should but the
headlamps ¯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 5-90.
If the alarm does not sound or the headlamps do not
¯ash, the vehicle should be serviced by your dealer.
Passlockž
Your vehicle is equipped with the
Passlockžtheft-deterrent system.
Passlockžis a passive theft-deterrent system.
Passlockženables 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 ®ve seconds after the key is turned
to RUN.
If the engine stalls and the security light ¯ashes, wait
about 10 minutes until the light stops ¯ashing 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
žsystem is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock
žat this
time. You may also want to check the fuse. See
Fuses and Circuit Breakers on page 5-90. See your
dealer for service.
In an emergency, call the GM Roadside Assistance
Center. See
Roadside Assistance Program on page 7-5.

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 ®nished, the lever will return
automatically.
An arrow on the instrument
panel cluster will ¯ash in
the direction of the
turn or lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to ¯ash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it. The bottom of the outside
rearview mirrors may also be equipped with lane change
indicators.
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 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. SeeFuses and Circuit Breakers
on page 5-90and check for burned-out bulbs.
If you have a trailer towing option with added wiring for
the trailer lamps, a different turn signal ¯asher is
used. With this ¯asher installed, the signal indicator will
¯ash even if a turn signal bulb is burned out. Check
the front and rear turn signal lamps regularly to make
sure they are working.
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 ¯ash of the
turn signal. To turn off the chime, move the turn signal
lever to the off position.
Headlamp High/Low-Beam Changer
To change the headlamps from low to high beam, push
the lever toward the instrument panel. To return to
low-beam headlamps, pull the multifunction lever toward
you. Then release it.

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.
Notice: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 amperage rating.
When adding electrical equipment, be sure to follow the
proper installation instructions included with the
equipment.
Notice: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.
Ashtrays and Cigarette Lighter
Your vehicle may have this feature. The ashtray is
removable and ®ts into the front cupholder.
Notice:Don't put papers or other ¯ammable
items into your ashtrays. Hot cigarettes or other
smoking materials could ignite them, causing
a damaging ®re.
To remove the ashtray, pull the covered bin out of the
cupholder.
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:Don't hold a cigarette lighter in with your
hand while it is heating. If you do, it won't be able to
back away from the heating element when it's
ready. That can make it overheat, damaging the
lighter and the heating element.

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 Ð shrubs, ¯owers, trees,
grasses Ð or disturb wildlife (this includes
wheel-spinning, breaking down trees or
unnecessary driving through streams or over soft
ground).
·Always carry a litter bag Ð 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's 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'll want to know
how to use it properly.
Getting Familiar with Off-Road Driving
It's a good idea to practice in an area that's safe
and close to home before you go into the wilderness.
Off-road driving does require some new and different
skills. Here's what we mean.
Tune your senses to different kinds of signals. Your
eyes, for example, need to constantly sweep the terrain
for unexpected obstacles. Your ears need to listen
for unusual tire or engine sounds. With your arms,
hands, feet and body, you'll need to respond to
vibrations and vehicle bounce.

Dinghy Towing
When towing your vehicle, turn the ignition off. To
prevent your battery from draining while towing, remove
the Ignition A and the Ignition B fuses from the engine
compartment fuse block. Be sure to reinstall the
fuse when you reach your destination.
Two-Wheel-Drive Vehicles
Two-wheel-drive vehicles should not be towed with all
four wheels on the ground. Two-wheel-drive
transmissions have no provisions for internal lubrication
while being towed. To properly tow these vehicles,
they should be placed on a platform trailer.
In rare cases when it's unavoidable that a
two-wheel-drive vehicle is to be towed with all four
wheels on the ground, the propeller shaft to axle yoke
orientation should be marked and the propeller shaft
removed following the applicable service manual
removal/installation procedure.
Dust or dirt can enter the back of the transmission
through the opening created by removing the propeller
shaft if proper protection is not provided. Also, check
the transmission ¯uid level before driving the truck.
Four-Wheel-Drive Vehicles
Use the following procedure to tow your vehicle:
1. Firmly set the parking brake.
2. Shift the transmission to PARK (P).
3. Securely attach the vehicle being towed to the tow
vehicle.

CAUTION: (Continued)
·
Be sure to use the proper nuts, bolts and
other fasteners. ªEnglishº and ªmetricº
fasteners can be easily confused. If you
use the wrong fasteners, parts can later
break or fall off. You could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the air¯ow around it. This may cause wind
noise and affect windshield washer performance. Check
with your dealer before adding equipment to the
outside of your vehicle.
Fuel
Use of the recommended fuel is an important part of the
proper maintenance of your vehicle.
Gasoline Octane
Use regular unleaded gasoline with a posted octane
of 87 or higher. If the octane is less than 87, you may
get a heavy knocking noise when you drive. If this
occurs, use a gasoline rated at 87 octane or higher as
soon as possible. Otherwise, you might damage
your engine. A little pinging noise when you accelerate
or drive uphill is considered normal. This does not
indicate a problem exists or that a higher-octane fuel is
necessary. If you are using 87 octane or higher-octane
fuel and hear heavy knocking, your engine needs
service.

Engine Oil
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 engine oil dipstick
handle is a yellow ring
located in the engine
compartment toward the
passenger's side of
the vehicle. See
Engine
Compartment Overview on
page 5-12
for more
information on location.
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.

Electrical System
Add-On Electrical Equipment
Notice:Don't add anything electrical to your
vehicle unless you check with your dealer ®rst.
Some electrical equipment can damage your vehicle
and the damage wouldn't be covered by your
warranty. Some add-on electrical equipment can
keep other components from working as they
should.
Your vehicle has an air bag system. Before attempting
to add anything electrical to your vehicle, see
Servicing Your Air Bag-Equipped Vehicle on page 1-60.
Headlamps
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
right away.
Windshield Wiper Fuses
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 ®xed.
