There is an air bag readiness light on the instrument
panel, which shows AIR
BAG. The system checks the
air bag’s electrical system for malfunctions. The light
tells you if there is an electrical problem. The system
check includes the air bag sensors, the air bag module,
the wiring and the diagnostic module. For more
information
on the air bag system, see “Air Bag” in
the Index.
AIR
BAG
You will see this light flash
for a few seconds when you
turn your ignition to RUN
or START. Then the light
should go
out. This means
the system is ready.
If the air bag readiness light doesn’t come on when you
start your vehicle, or stays on,
or comes on when you
are driving, your air bag system may not work properly.
Have your vehicle serviced right away.
Charging System Indicator Light
The charging system light
will come on briefly when
you turn on the ignition,
but the engine is not
running, as a check to
show you it is working.
It should go
out once the engine is running. If it stays
on, or comes on while you are driving, you may have a
problem with the charging system. It could indicate that
you have problems with a generator drive belt, or
another electrical problem. Have it checked right away.
Driving while
this light is on could drain your battery.
If you must drive a short distance with the light on, be
certain
to turn off all your accessories, such as the radio
and air conditioner.

I
When your engine is not
running, but the ignition is
on (in the RUN position),
this gage shows your
battery’s state
of charge in
DC volts.
When the engine is running, the gage shows the
condition of the charging system. Readings between the
low and high warning zones indicate the normal
operating range.
Readings in the low warning zone may occur when a.
large number
of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This condition is normal since the
charging system is
not able to provide full power at
engine idle.
As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system
to create maximum power.
You can only drive for a short time with the reading in
either warning zone.
If you must drive, turn off all
unnecessary accessories.
Readings
in either warning zone indicate a possible
problem
in the electrical system. Have the vehicle
serviced as soon as possible.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part isn’t working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.
This light should come
on
briefly when you turn the
ignition key to RUN. If it
doesn’t come on then, have
it fixed
so it will be ready to
warn you if there’s a
problem.
2-67

Downloaded from www.Manualslib.com manuals search engine If the light comes on while you are driving, pull off the
road and stop carefully.
You may notice that the pedal is
harder to push. Or, the pedal
may go closer to the floor.
It may take longer to stop. If the light is still on, have the
vehicle towed for service. (See “Towing Your Vehicle”
,
in the Index.)

Anti-Lock Brake System Warning Light
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on
can lead
to an accident. If the light
is still on after you’ve
pulled off the road and stopped carefully, have
the vehicle towed for service.
When the ignition is on, the brake system warning light
will also come
on when you set your parking brake. The
light will stay
on if your parking brake doesn’t release
fully. If it stays
on after your parking brake is fully
released, it means you have a brake problem.
ANTI - LOCK
With the anti-lock brake
system, this light will
come
on when you start
your engine and may stay
on for several seconds.
That’s normal.
If the light stays
on, or comes on when you’re driving,
your vehicle needs service. If the regular brake system
warning light isn’t
on, you still have brakes, but you
don’t have anti-lock brakes. If the regular brake system
warning light is
also on, you don’t have anti-lock brakes
and there’s
a problem with your regular brakes. See
“Brake System Warning Light” earlier
in this part.
The anti-lock brake system warning light should come
on briefly when
you turn the ignition key to RUN. If the
light doesn’t come
on then, have it fixed so it will be
ready to warn
you if there is a problem.

engine is too hot!
Malfunction Indicator Lamp
(Service Engine Soon Light)
SERVICE
ENGINE
SOON
Your vehicle is equipped
with a computer which
monitors operation
of the
fuel, ignition and emission
control systems.
It means that your engine coolant has overheated. If
you
have been operating your vehicle under normal driving
conditions,
you should pull off the road, stop your
vehicle and turn
off the engine as soon as possible.
In “Problems
on the Road,” this manual shows you what
to do. See “Engine Overheating” in the Index. 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. (In Canada, OBD
I1 is replaced by
Enhanced Diagnostics.) The SERVICE ENGINE
SOON light comes on to indicate that there is a
problem and 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.
2-69

Downloaded from www.Manualslib.com manuals search engine NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not work as well, your fuel economy may not be. as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is
on and the engine is not
running. If the light doesn’t come on, have
it repaired.
This light will
also come on during a malfunction in one
of two ways:
0
0
Light Flashing -- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service is required.
Light On Steady -- An emission control system
malfunction has been detected
on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
0 Avoid steep uphill grades.
0 If towing a trailer, reduce the amount of cargo being
hauled as soon as it
is possible.
If the light stops flashing and remains
on steady, see “If
the Light Is On Steady” following.
If the light continues to flash, when it
is safe to do so,
stop the vehicle. Put your vehicle in PARK (P). Turn the
key off, wait at least
10 seconds and restart the engine.
If the light remains on steady, see
“If the Light Is On
Steady” following. If the light is still flashing follow the
previous steps, and drive the vehicle
to your dealer or
qualified service center for service.

Downloaded from www.Manualslib.com manuals search engine If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering
the following:
Did
you just put fuel into your vehicle?
If
so, reinstall the fuel cap, making sure to fully install
the cap. The diagnostic system
can determine if the fuel
cap has been left off or improperly installed. This will
allow fuel to evaporate
into the atmosphere. A few
driving trips should turn the light
off.
Have you recently changed brands of fuel?
Did
you just drive through a deep puddle of water?
If
so, your electrical system may be wet. The condition
will usually be corrected when
the electrical system
dries out. A few driving trips should turn
the light off.
Are
you low on fuel?
As your engine starts to run out of fuel, your engine
may
not run as efficiently as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure
to install the fuel cap properly. It
will take a few driving trips to turn the light off. If
so, be
sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). Poor
fuel quality will cause your
engine
not to run as efficiently as designed. You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling
on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause
the light
to turn on.
If you experience this condition, change the fuel brand
you use. It will require at least one full tank of the
proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools
to fix any mechanical or electrical
problems that may have developed.

OIL 0-
The oil pressure gage shows
the engine oil pressure in
psi (pounds per square inch)
when the engine
is running.
Canadian vehicles indicate pressure in kPa (kilopascals).
Oil pressure may vary with engine speed, outside
temperature
and oil viscosity, but readings above the
low pressure zone indicate the normal operating range.
A reading in the low pressure zone may be caused by a
dangerously
low oil level or other problems causing low
oil pressure.
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.

Downloaded from www.Manualslib.com manuals search engine Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes or
a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight and
extreme heat. If
they aren’t, they may not operate
properly or may cause failure of the tape player.
Your tape player should be cleaned regularly after every
50 hours of use. If you notice a reduction in sound
quality, try a known good cassette
to see if the tape or
the tape player is at fault. If this other cassette has
no
improvement in sound quality, clean the tape player.
Cleaning may be done with
a scrubbing action,
non-abrasive cleaning cassette with pads which scrub
the tape head as the hubs of the cleaner cassette turn. It
is normal for the cassette
to eject while cleaning. Insert
the cassette at le.ast three times to ensure thorough
cleaning.
A scrubbing action cleaning cassette is
available through your
GM dealer.
You may also choose
a non-scrubbing action, wet-type
cleaner which uses a cassette with a fabric belt
to clean
the tape head. This type of cleaning cassette will not
eject. It may not clean as thoroughly as the scrubbing
type cleaner. Cassettes are subject
to wear and the sound quality may
degrade over time. Always make sure that the cassette
tape
is in good condition before you have your tape
player serviced.
Care of Your Compact Discs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust.
If the surface of a disc is soiled, dampen a
clean, soft cloth in a mild, neutral detergent solution and
clean it, wiping from the center
to the edge.
Be sure never to touch
the signal surface when handling
discs. Pick up discs by grasping
the outer edges or the
edge
of the hole and the outer edge.
Fixed Mast Antenna
The fixed mast antenna can withstand most car washes
without being damaged.
If the mast should ever become
slightly bent,
you can straighten it out by hand. If the
mast
is badly bent, as it might be by vandals, you should
replace
it.
Check every once in a while to be sure the mast is still
tightened to the fender.

Downloaded from www.Manualslib.com manuals search engine 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.
Loading Your Vehicle for Off-Road Driving
There are some important things to remember about
how to load your vehicle.
0 The heaviest things should be on the load floor and
forward of your rear axle. Put heavier items as far
forward as you can.
Be sure the load is secured properly, so driving on
the off-road terrain doesn’t toss things around.
A CAUTION:
0 Cargo on the load floor piled higher than
the seatbacks can be thrown forward
during a sudden stop. You or your
passengers could be injured. Keep cargo
below the top of the seatbacks.
Unsecured cargo on the load floor can
be tossed about when driving over rough
terrain. You or your passengers can
be struck by flying objects. Secure the
cargo properly,
Heavy loads on the roof raise the vehicle’s
center of gravity, making it more likely to
roll over. You can be seriously
or fatally
injured if the vehicle rolls over, Put heavy
loads inside the cargo area, not on the roof,
Keep cargo in the cargo area as far forward
and low as possible.
You’ll find other important information in
this manual.
See “Vehicle Loading,” “Luggage Carrier” and “Tires”
in the Index.

Downloaded from www.Manualslib.com manuals search engine 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
I
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.
