SeePassenger Sensing System on page 89for
more on this, including important safety information.
If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your dealer for service.
{CAUTION:
If the off indicator and the airbag
readiness light ever come on together, it
means that something may be wrong with
the airbag system. If this ever happens,
have the vehicle serviced promptly,
because an adult-size person sitting in the
right front passenger seat may not have
the protection of the frontal airbag. See
Airbag Readiness Light on page 169.
Charging System Light
This light should come
on briefly when you turn
on the ignition, before
starting the engine, as a
check to show you it
is working.
After the engine starts, the light should go out. If it
stays on or comes on while you are driving, you
may have a problem with your charging system.
It could indicate a problem with the generator drive
belt, or some other charging system problem.
Have it checked right away. Driving while this light
is on could drain your battery.
If you must drive a short distance with this light
on, it helps to turn off all your accessories, such as
the radio and air conditioner.

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. SeeBrake System
Warning Light on page 175for more information.
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.
StabiliTrak®Not Ready Light
If your vehicle has the
StabiliTrak®system,
this light will come on
according to the
description table for the
StabiliTrak
®system.For more information, seeStabiliTrak
®System on
page 235.
You will hear three chimes if the light turns on and
one chime if the light turns off.
StabiliTrak®Indicator Light
If you have the
StabiliTrak®system,
this light will be on or
flashing, according to
the description table for
the StabiliTrak
®system.
For more information, seeStabiliTrak
®System on
page 235.
You will hear three chimes if the light turns on and
one chime if the light turns off.
If this light remains on steady, your vehicle needs
to be taken in for service.

Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
If the gage pointer moves into the red area
your engine is too hot!
It means that your engine coolant has overheated.
If you have been operating your vehicle under
normal operating conditions, you should pull off the
road, stop your vehicle, and turn off the engine
as soon as possible.
SeeEngine Overheating on page 309.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which
monitors operation of
the fuel, ignition,
and emission control
systems.
This system is called OBD II (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 Check Engine 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. This may prevent more serious damage
to your vehicle. This system is also designed to
assist your service technician in correctly
diagnosing any malfunction.

For best results, use a scrubbing action,
non-abrasive cleaning cassette with pads which
scrub the tape head as the hubs of the cleaner
cassette turn. The recommended cleaning cassette
is available through your dealer.
When cleaning the cassette tape player with the
recommended non-abrasive cleaning cassette, it is
possible that the cassette may eject, because
the cut tape detection feature on the radio
may recognize it as a broken tape, in error.
To prevent the cleaning cassette from being
ejected, use the following steps:
1. Turn the ignition on.
2. Turn the radio off.
3. Press and hold the TAPE DISC button for
five seconds. READY will appear on the
display and the cassette symbol will flash for
five seconds.
4. Insert the scrubbing action cleaning cassette.5. Eject the cleaning cassette after the
manufacturer’s recommended cleaning time.
When the cleaning cassette has been ejected,
the cut tape detection feature will be active
again.
A non-scrubbing action, wet-type cleaner which
uses a cassette with a fabric belt to clean the tape
head can be used. This type of cleaning cassette
will not eject on its own. A non-scrubbing
action cleaner may not clean as thoroughly as the
scrubbing type cleaner. The use of a
non-scrubbing action, dry-type cleaning cassette is
not recommended.
After the player is cleaned, press and hold the
eject button for five seconds to reset the CLEAN
indicator. The radio will display --- or CLEANED to
show the indicator was reset.
Cassettes are subject to wear and the sound
quality may degrade over time. Always make sure
the cassette tape is in good condition before
the tape player is serviced.

Some gasolines that are not reformulated for low
emissions may contain an octane-enhancing
additive called methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant where you
buy gasoline whether the fuel contains MMT.
General Motors recommends against the use of
such gasolines. Fuels containing MMT can reduce
the life of spark plugs and the performance of
the emission control system may be affected. The
malfunction indicator lamp may turn on. If this
occurs, return to your dealer for service.
Fuel E85 (85% Ethanol)
The 8th digit of your Vehicle Identification Number
(VIN) shows the code letter or number that
identifies your engine. You will find the VIN at the
top left of the instrument panel. SeeVehicle
Identication Number (VIN) on page 386.
If your vehicle has the 5.3L V8 engine
(VIN Code Z only), you may use either regular
unleaded gasoline or ethanol fuel containing up to
85% ethanol (E85); also seeFuel on page 288.
In all other engines, use only the unleaded
gasoline described underGasoline Octane on
page 288.Only vehicles that have the 5.3L V8 engine
(VIN Code Z) may use 85% ethanol fuel (E85).
General Motors encourages the use of E85
in vehicles that are designed to use it. The ethanol
in E85 is a “renewable” fuel, meaning it is made
from renewable sources such as corn and
other crops.
Many service stations will not have an
85% ethanol fuel (E85) pump available.
The U. S. Department of Energy has an
alternative fuels website (www.eere.energy.gov/
afdc/infrastructure/locator.html) that can help
you find E85 fuel. Those stations that do have
E85 should have a label indicating ethanol content.
Do not use the fuel if the ethanol content is
greater than 85%.
At a minimum, E85 should meet ASTM
Specification D 5798. By definition, this means
that fuel labeled E85 will have an ethanol content
between 70% and 85%. Filling the fuel tank
with fuel mixtures that do not meet ASTM
specifications can affect driveability and could
cause the check engine light to come on.

Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that
make a high-pitched warning sound when the
brake pads are worn and new pads are needed.
The sound may come and go or be heard all
the time your vehicle is moving, except when you
are pushing on the brake pedal firmly.
{CAUTION:
The brake wear warning sound means that
soon the brakes will not work well. That
could lead to an accident. When you hear
the brake wear warning sound, have your
vehicle serviced.
Notice:Continuing to drive with worn-out
brake pads could result in costly brake repair.Some driving conditions or climates may cause a
brake squeal when the brakes are first applied
or lightly applied. This does not mean something
is wrong with your brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated,
inspect brake pads for wear and evenly tighten
wheel nuts in the proper sequence to GM torque
specifications.
Brake linings should always be replaced as
complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does not return
to normal height, or if there is a rapid increase in
pedal travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you make a brake stop, your disc
brakes adjust for wear.
