Indicator lights go on when you use your turn signals, change from low
beam headlights
to high beams, or when you use your hazard flashers. The
next few pages will also tell you about the indicator lights on your vehicle
and help
you locate them.
Malfunction Indicator Lamp (SERVICE ENGINE SOON
Light)
The amber
Malfunction Indicator
Lamp (SERVICE
ENGINE SOON
Light) is located at the
top of your instrument
panel.
SERVICE
ENGINE
SOON
A computer monitors operation of your fuel, ignition and emission control
systems. This light should come
on when the ignition is on, but the engine is
not running, as a check to show you it is working. If it does not come
on at
all, have it fixed right away.
If it stays on, or it comes on while you are
driving, the computer is indicating that
you have a problem. You should
take your vehicle in for service
soon.
NOTICE:
If you keep driving your vehicle with this light on, after awhile
the emission controls won’t work as well, your fuel economy
won’t be as good and your engine may not run as smoothly. This
could lead
to costly repairs not covered by your warranty.
If Your Vehicle is Equipped with OBD I1
Certain vehicles with 4.3 liter engines are equipped with a new emission
diagnostic system. You can tell whether your vehicle has this system
by
reading your tune-up label located under the hood. If the label says “OBD
11” on it, the following instructions apply.

Downloaded from www.Manualslib.com manuals search engine Malfunction Indicator Lamp (SERVICE ENGINE SOON Light)
Your vehicle is equipped with an onboard computer which monitors
operation of the emission control system. This system is called OBD I1
(On-Board Diagnostics-Second Generation) and is intended to assure that
emissions are at acceptable levels for the life of the vehicle, helping to
produce a cleaner environment. The “SERVICE ENGINE
SOON’ light
comes on to indicate when service is required. Malfunctions often will be
indicated by
the system before any problem is apparent, which may prevent
more serious damage to your vehicle. This system is also designed to assist
your service technician in correctly diagnosing any malfunction.
The “SERVICE ENGINE
SOON, light should come on, as a check to show
you it is working, when the ignition is on and the engine is not running. This
light will also come during a malfunction in one
of two ways:
0
0
Light on steady - indicates a system malfunction has been detected.
Drive the vehicle to the dealer for service at your first opportunity.
Light flashing
- indicates a misfire has been detected which may
damage the emission control system. The damage may be reduced by
lowering the vehicle speed, reducing the amount of cargo being hauled
or trailered, avoiding hard acceleration, or by avoiding steep uphill
grades.
If these actions are effective, the light will stop flashing and
remain on steady. Drive the vehicle to a dealer for service. If the light
continues to flash, stop the vehicle. Wait for a steady light to come on,
then drive the vehicle to a dealer for service.
These following conditions also may cause the “SERVICE ENGINE
SOON” light to come on:
Low FueVOut of Fuel
- As the vehicle starts to run out of fuel the
“SERVICE ENGINE
SOON” light may come on as a result of an engine
misfire. Filling your gasoline tank should correct this condition. Make sure
to install the gas cap fully. It will require a few driving trips to turn the light
off.
Poor Quality Fuel
- Be sure to fuel your vehicle with quality fuel. Your
engine may not run efficiently on poor fuel. Poor fuel may cause stalling,
hesitation or misfire. These conditions may go away when the engine is
warned-up. However, poor quality fuel may cause the “SERVICE ENGINE
SOON, light to come on.
Have a dealer check the vehicle. If no problems are found, you may want to
change to another brand
of fuel.
Driving Through Standing Water
- Driving your vehicle through puddles
of deep standing water may result in a temporary misfire condition. This
condition will usually correct itself shortly after the electrical system dries
out. It will require a few driving trips to turn the light off.

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
Don’t keep driving if the oil pressure is low. If you do, your
engine can become
so hot that it catches fire. You or others could
be burned. Check your oil
as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil problems can be
costly and is not covered
by your warranty.
Fuel Gage
The fuel gage tells
you about how much
fuel you have
remaining when the
ignition
is on. When
the gage first indicates
empty, you still have a
little fuel left, but you
should get more fuel
soon.
Here are four things that some owners ask about. None of these show a
problem with your fuel gage:
At the gas station, the gas pump shuts off before the gage reads full.
0 It takes a little more or less fuel to fill up than the gage indicated. For
example, the gage may have indicated the tank was half full, but it
actually took a little more or less than half the tank’s capacity to fill the
tank.
0 The gage moves a little when you turn a corner or speed up.
The gage doesn’t go back to empty when you turn off the ignition.
For your fuel tank capacity, see the Index under “Fluid Capacities.”

Downloaded from www.Manualslib.com manuals search engine The lower knob selects the heater or air conditioning function and
determines which outlets the air will flow through (instrument panel,
defroster, heater, etc.).
OFF - This setting turns off all heating functions. Some outside air will
still come out of the heater outlet whenever the vehicle is moving forward.
MAX A/C
- Air inside your vehicle is recirculated to maximize your air
conditioner’s performance and your vehicle’s fuel economy. This setting
cools the air the fastest and should be used to keep “unwanted odors” and/or
dust from entering the vehicle.
NORM A/C - This setting cools outside air and directs it through the
instrument panel vents. This setting is useful for normal cooling on hot
days.
BI-LEV A/C
- Air is delivered through the heater floor vents as well as
the instrument panel vents. This setting is useful in cool weather with bright
sunlight.
VENT - Airflow is through the instrument panel vents. Set the upper knob
to the temperature desired. This setting is useful for mild outside
temperatures, when little heating or cooling is desired. The air conditioner
does not run.
HEAT
- Heated air comes out through the heater floor vents and
windshield defroster vents. This setting is useful for cold weather.
BLEND
- Airflow is divided equally between the heater floor vent and the
windshield defroster vents. This setting
is useful in cool weather when you
have fog or ice on the windshield
or side windows.
DEF - This setting directs most air through the windshield defroster vents
and some through the heater vents. This setting is useful when you have fog
or ice on the windshield.
Engine Coolant Heater (Option)
If you use the optional engine coolant heater before starting your engine,
your heating system
will produce warmer air faster, to heat the passenger
compartment
in cold weather. See “Engine Coolant Heater” in the Index.

Downloaded from www.Manualslib.com manuals search engine Remember: If you have the four-wheel anti-lock braking system, it helps
avoid only the braking skid. The rear-wheel anti-lock braking system helps
avoid only a rear braking skid. In a braking skid (where the front wheels are
no longer rolling), release enough pressure
on the brakes to get the front
wheels rolling again. This restores steering control. Push the brake pedal
down steadily when you have to stop suddenly. As long as the front wheels
are rolling, you will have steering control.
Driving Guidelines
OR-Road Driving with Your Four-wheel Drive
Vehicle
This off-road guide is for vehicles that have four-wheel drive.
Also, see “Anti-Lock Brakes” in the Index.
If your vehicle doesn’t have four-wheel drive, you shouldn’t drive off-road
unless you’re on a level, solid surface.
Off-road driving can be great fun. But it does have some definite hazards.
The greatest of these is the terrain itself.
“Off-roading” means you’ve left the great North American road system
behind. Traffic lanes aren’t marked. Curves aren’t banked. There are no
road signs. Surfaces can be slippery, rough, uphill or downhill. In short,
you’ve gone right back to nature.
Off-road driving involves some new skills. And that’s why it’s very
important that
you read this guide. You’ll find many driving tips and
suggestions. These will help make your off-road driving safer and more
enjoyable.
Before You Go Off-Roading
There are some things to do before you go out. For example, be sure to have
all necessary maintenance and service work done. Check to make sure all
underbody shields (if
so equipped) are properly attached. Be sure you read
all the information about your four-wheel drive vehicle
in this manual. Is
there enough fuel? Is the spare tire fully inflated? Are the fluid levels up
where they should be? What are the local laws that apply to off-roading
where you’ll be driving? If you don’t know, you should check with law
enforcement people in the area. Will you be
on someone’s private land? If
so, be sure to get the necessary permission.

Downloaded from www.Manualslib.com manuals search engine Driving through rushing water can be dangerous. Deep water can sweep your vehicle downstream and you and your
passengers
could drown. If it’s only inches deep, it can still wash
away the ground from under your tires, and you could lose
traction and roll the vehicle over. Ron’t drive through rush\
ing water.
After Off-Road Driving
Remove any brush or debris that has collected on the underbody, chassis or
under the hood. These accumulations can be a fire hazard.
After operation in mud
or sand, have the brake linings cleaned and checked.
These substances can cause glazing and uneven braking. Check the body
structure, steering, suspension, wheels, tires, and exhaust system for
damage. Also, check the fuel lines and cooling system for any leakage.
Your vehicle will require more frequent service due to off-road
use. Refer
to the Maintenance Schedule for additional information.
Driving at Night
Night driving is more dangerous than day driving. One reason is that some
drivers
are likely to be impaired - by alcohol or drugs, with night vision
problems, or by fatigue.

Downloaded from www.Manualslib.com manuals search engine The exit ramp can be curved, sometimes quite sharply.
The
exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of
motion. After driving for any distance at higher speeds, you may tend to
think you are going slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you must start when you’re
not fresh
- such as after a day’s work - don’t plan to make too many
miles that first part of the journey. Wear comfortable clothing and shoes you
can easily drive
in.
Is your vehicle ready for a long trip? If you keep it serviced and maintained,
it’s ready to
go. If it needs service, have it done before starting out. Of
course, you’ll find experienced and able service experts in GM dealerships
all across North America. They’ll be ready and willing to help if you need
it.
Here are some things you can check before a trip:
Windshield Washer Fluid: Is the reservoir full? Are all windows clean
inside and outside?
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked all levels?
Lights: Are they all working? Are the lenses clean?
0 Tires: They are vitally important to a safe, trouble-free trip. Is the tread
good enough for long-distance driving? Are the tires all inflated to the
recommended pressure?
Weather Forecasts: What’s the weather outlook along your route?
Maps: Do you have up-to-date maps?
Should
you delay your trip a short time to avoid a major storm system?
Highway Hypnosis
Is there actually such a condition as “highway hypnosis”? Or is it just plain
falling asleep at the wheel? Call it highway hypnosis, lack of awareness, or
whatever.
There
is something about an easy stretch of road with the same scenery,
along with the hum of the tires on the road,
the drone of the engine, and the
rush of the wind against the vehicle that can make you sleepy. Don’t let it
happen to you! If it does, your vehicle can leave the road in
less than a
second,
and you could crash and be injured.
What can you
do about highway hypnosis? First, be aware that it can
happen.

Downloaded from www.Manualslib.com manuals search engine Run your engine only as long as you must. This saves fuel. When you run
the engine, make it go
a little faster than just idle. That is, push the
accelerator slightly. This uses less fuel for the heat that you get and
it keeps
the battery charged. You will need
a well-charged battery to restart the
vehicle, and possibly
for signaling later on with your headlamps. Let the
heater run
for awhile.
Then, shut the engine off and close the window almost all the way to
preserve the heat. Start the engine again and repeat this only when you feel
really uncomfortable from the cold. But do
it as little as possible. Preserve
the fuel
as long as you can. To help keep warm, you can get out of the
vehicle and
do some fairly vigorous exercises every half hour or so until
help comes.
