2-56 Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. 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 modules, the wiring
and the crash sensing and diagnostic module. For more
information on the air bag system, see ªAir Bagº
in the Index.
This light will come on
when you start your vehicle,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inflate in a crash, or they
could even inflate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to ON. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.

2-57 Charging System Light
The charging system light
will come on briefly when
you turn the ignition key to
ON as a check to show you
it's working. Then it should
go out.
If it stays on, or comes on while you're driving, you
may have a problem with the charging system. It could
indicate that you have a loose 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.
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 is a brake problem.
Have your brake system inspected right away.
United States Canada
This light should come on briefly when you turn the
ignition key to ON. If it doesn't come on then, have it
fixed so it will be ready to warn you if there's a problem.
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 ªTowing Your Vehicleº
in the Index.)

2-59 Traction Control System Warning
Light (Option)
This warning light should
come on briefly as you start
the engine.
If the warning light doesn't come on then, have it fixed
so it will be ready to warn you if there's a problem. If it
stays on, or comes on when you're driving, there may be
a problem with your traction control system and your
vehicle may need service. When this warning light is on,
the system will not limit wheel spin. Adjust your
driving accordingly.The traction control system warning light may come on
for the following reasons:
If you turn the system off by pressing the
TRACTION CONTROL button located on the
console, the warning light will come on and stay on.
To turn the system back on, press the button again.
The warning light should go off. (See ªTraction
Control Systemº in the Index for more information.)
If there's a brake system problem that is specifically
related to traction control, the traction control system
will turn off and the warning light will come on. If
your brakes begin to overheat, the traction control
system will turn off and the warning light will come
on until your brakes cool down.
If the traction control system is affected by an
engine
-related problem, the system will turn off and
the warning light will come on.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.

2-61
The optional Traction Control System is active and is
limiting wheel spin. You may feel the system
working, but this is normal. Slippery road conditions
may exist, so adjust your driving accordingly.
If the LOW TRAC light comes on, slippery road
conditions may exist, so you should consider slowing
down and adjusting your driving accordingly.
Engine Coolant Temperature Gage
You have a gage that
shows the engine coolant
temperature. If the gage
moves into the red area,
your engine is too hot.That reading means the same thing as the warning light.
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.
See ªEngine Overheatingº in the Index.
Low Coolant Warning Light
If this light comes on, your
system is low on coolant,
and the engine
may overheat.
This light will come on briefly when the ignition is
turned to ON. This is normal.
See ªEngine Coolantº in the Index for more
information, and have your vehicle serviced as
soon as possible.

If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. See ªFilling Your Tankº in the Index. The
diagnostic system can determine if the fuel cap has been
left off or improperly installed. A loose or missing fuel
cap will allow fuel to evaporate into the atmosphere. A
few driving trips with the cap properly installed should
turn the light off.
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. See
ªFilling Your Tankº in the Index. It will take a few
driving trips to turn the light off.Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel
(see ªFuelº 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 one or more of these conditions,
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.

2-67 Low Oil Level Light
Your engine is equipped
with an oil level monitoring
system. When the ignition is
turned to ON, the LOW
OIL LEVEL light will
briefly come on.
If the light does not flash, have it fixed so it will be
ready to warn you if there's a problem.
If the light stays on, stop the vehicle on a level surface
and turn the engine off. Check the oil level using the
engine oil dipstick. (See ªEngine Oilº in the Index.)
The oil level monitoring system only checks oil level
during the brief period between key on and engine
crank. It does not monitor engine oil level when the
engine is running. Additionally, an oil level check is
only performed if the engine has been turned off for an
extended period of time, allowing the oil normally in
circulation to drain back into the oil pan.
Change Oil Light
The CHANGE OIL light
should come on briefly as a
bulb check when you start
the engine. If the light
doesn't come on, have the
vehicle serviced right away.
If the CHANGE OIL light comes on and stays on after
you start the engine, have the oil changed.
For additional information see ªEngine Oil, When to
Changeº in the Index. To reset the GM Oil Life
System, see ªHow to Reset the Change Oil Lightº in
the Index.

2-68 Security Light
This light will come on
when you turn the key to
ON and will stay on until
the engine starts.
If you're driving and the SECURITY light comes on
and stays on, your Passlock
system is not working
properly. Your vehicle is not protected by Passlock and
you should see your dealer.
Cruise Light
The CRUISE light comes
on whenever you set your
cruise control. See ªCruise
Controlº in the Index.
Low Washer Fluid Light
This light will come on
when your ignition is on to
check the bulb and will
come on when your washer
fluid is low.
