Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning
light will come on
when the engine
has overheated.
If this happens you should pull over and turn off
the engine as soon as possible. SeeEngine
Overheating on page 351for more information.
Notice:Driving with the engine coolant
temperature warning light on could cause your
vehicle to overheat. SeeEngine Overheating
on page 351. Your vehicle could be damaged,
and it might not be covered by your warranty.
Never drive with the engine coolant
temperature warning light on.
This light will also come on briey when starting
your vehicle. If it does not, have your vehicle
serviced.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature. If
the pointer moves towards the H (United States) or
shaded in thermostat symbol area (Canada), the
engine is too hot.
A temperature indicator light will turn on and a
chime will sound.
If you have been operating your vehicle under
normal driving conditions, and the temperature
indicator light comes on, you should pull off
the road, stop your vehicle and turn off the
engine as soon as possible.

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.Notice:If you keep driving your vehicle with
this light on, after awhile, 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.
Notice:Modications made to the engine,
transaxle, exhaust, intake, or fuel system of
your vehicle or the replacement of the original
tires with other than those of the same Tire
Performance Criteria (TPC) can affect your
vehicle’s emission controls and may cause
this light to come on. Modications to these
systems could lead to costly repairs not
covered by your warranty. This may also
result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 325.

Fuel Gage
The fuel gage shows about how much fuel is in your
tank. It works only when the ignition is on. When the
indicator moves to the edge of the low fuel warning
band, the low fuel warning light will come on and a
chime will sound. You still have a little fuel left, but
you need to get more fuel right away.Here are some things that some owners ask
about. None of these show a problem with your
fuel gage:
At the service station, the gas pump shuts off
before the gage reads full.
It takes more (or less) fuel to ll up than the
gage indicated. For example, the gage may
have indicated half full, but it took more
(or less) than half the tank’s capacity to ll it.
The gage moves up a little when you turn a
corner, speed up or make a hard stop.
The gage does not go back to empty when
you turn off the ignition.United StatesCanada

Driver Information Center (DIC)
Your vehicle has a Driver Information Center (DIC).
All messages will appear in the DIC display
located below the speedometer in the instrument
panel cluster. The DIC buttons are located on
the instrument panel, to the left of the instrument
panel cluster.
The DIC comes on when the ignition is on. After a
short delay, the DIC will display the information
that was last displayed before the engine was
turned off.
The DIC displays trip, fuel, and vehicle system
information, and warning messages if a system
problem is detected. The bottom line of the
DIC shows the shift lever position indicator.
SeeAutomatic Transaxle Operation on page 119
for more information.If your vehicle’s DIC has these features, the
compass direction and the outside air temperature
may also display on the DIC when viewing the
trip and fuel information. The compass direction
appears on the top right corner of the DIC display.
The outside air temperature automatically
appears in the bottom right corner of the DIC
display. If there is a problem with the system that
controls the temperature display, the numbers
will be replaced with dashes. If this occurs, have
the vehicle serviced by your dealer.
The DIC also allows some features to be
customized. SeeDIC Vehicle Customization on
page 231for more information.
DIC Controls and Displays
The DIC has different displays which can be
accessed by pressing the DIC buttons located on
the instrument panel, to the left of the instrument
panel cluster.

The SERVICE TRACTION CONTROL message,
the traction control system warning light and
the StabiliTrak
®warning light will come on to let
you know if there is a problem with the traction
control system. SeeDIC Warnings and Messages
on page 221.
When this light and the SERVICE TRACTION
CONTROL message are on, the system will not
limit wheel spin. Adjust your driving accordingly.
The traction control system automatically
comes on whenever you start your vehicle.
To limit wheel spin, especially in slippery road
conditions, you should always leave the system
on. But you can turn the traction control system off
if you ever need to.
You can turn the system on or off at any time by
pressing the traction control system button located
on the console. The DIC will display TRACTION
CONTROL OFF when you press the button.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 325for more information.
StabiliTrak®System
Your vehicle may have this feature. The
StabiliTrak®system is an advanced computer
controlled system that helps the driver maintain
directional control of the vehicle in difficult driving
conditions. This is accomplished by selectively
applying any one of the vehicle’s brakes and
reducing engine power. The StabiliTrak
®system
comes on automatically whenever you start
your vehicle. The system cannot be turned off.
The STABILITRAK NOT READY message may be
displayed in the DIC and the traction control system
and StabiliTrak
®warning light on the instrument
panel cluster will be on after rst driving the vehicle
and exceeding 19 mph (30 km/h) for 30 seconds.
The StabiliTrak
®system is off until the light has
turned off. This could take up to 15 minutes.
The traction control system and StabiliTrak
®
warning light on the instrument panel cluster will
ash when the system is operating. SeeTraction
Control System (TCS) Warning Light on page 202,
StabiliTrak
®Indicator Light on page 203andDIC
Warnings and Messages on page 221for more
information. You may also feel or hear the system
working. This is normal.

Gasolines containing oxygenates, such as ethers
and ethanol, and reformulated gasolines may
be available in your area. General Motors
recommends that you use these gasolines if they
comply with the specications described earlier.
However, E85 (85% ethanol) and other fuels
containing more than 10% ethanol must not be
used in vehicles that were not designed for
those fuels.
Notice:Your vehicle was not designed for
fuel that contains methanol. Do not use
fuel containing methanol. It can corrode metal
parts in your fuel system and also damage
the plastic and rubber parts. That damage
would not be covered under your warranty.
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.
Fuels in Foreign Countries
If you plan on driving in another country outside
the United States or Canada, the proper fuel may
be hard to nd. Never use leaded gasoline or
any other fuel not recommended in the previous
text on fuel. Costly repairs caused by use of
improper fuel would not be covered by your
warranty.
To check the fuel availability, ask an auto club, or
contact a major oil company that does business
in the country where you will be driving.

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 rmly.
{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 rst 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
specications.
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 apply the brakes, with or without
the vehicle moving, your brakes adjust for wear.
