Temperature Gage on page 3-42for more information.
Stop the vehicle and let the engine idle in PARK (P)
for a few minutes to allow the coolant to reach a

panel cluster and/or DIC, stop the vehicle as soon as
possible. Do not increase the engine speed above
normal idling speed. SeeEngine Overheating
on page 5-24for more information.

charging system, this message will appear on the
DIC. Under certain conditions, the charging system light
may also turn on in the instrument panel cluster. See
Charging System Light on page 3-38. The battery

means there may be a problem with your StabiliTrak®
system. If you see this message try to reset the system.
Stop; turn off the engine; then start the engine again.If the SERVICE STABILITY message still comes on,
it means there is a problem. You should see your
GM dealer for service. The vehicle is safe to drive,
however, you do not have the benet of StabiliTrak
®,
so reduce your speed and drive accordingly.
For more information on the StabiliTrak
®system, see
StabiliTrak®System on page 4-9.

This message will be displayed if any of the tire monitor
sensors have malfunctioned, if the tire monitor sensors
have not been programmed or if the recommended
tire pressures are not programmed. See your GM dealer
for service. Pressing any of the four DIC buttons or
the trip odometer reset stem will acknowledge the
message and clear it from the DIC display.
STABILITY SYS (System) ACTIVE
You may see the STABILITY SYS ACTIVE message on
the DIC. It means that an advanced computer-controlled
system has come on to help your vehicle continue to
go in the direction in which you are steering.
For more information on the StabiliTrak
®system, see
StabiliTrak®System on page 4-9.
3-60

STABILITY SYS (System) DISABLED
The STABILITY SYS DISABLED message will turn on
when you press the StabiliTrak®button, or when
the stability control has been automatically disabled.
There are four conditions that can cause this message
to appear.
One condition is overheating, which could occur if
StabiliTrak®activates continuously for an extended
period of time.
The message will also be displayed if the brake
system warning light is on. SeeBrake System
Warning Light on page 3-39.
The message could be displayed if the stability
system takes longer than usual to complete its
diagnostic checks due to driving conditions.
Also, if an engine or vehicle related problem has
been detected, and the vehicle needs service,
the message will appear. See your GM dealer.
The message will turn off as soon as the conditions that
caused the message to be displayed are no longer
present.
For more information on the StabiliTrak
®system, see
StabiliTrak®System on page 4-9.
TIGHTEN FUEL CAP
If the vehicle’s fuel cap is not tightened properly this
message may appear along with the check engine light
on the instrument panel. SeeMalfunction Indicator
Lamp on page 3-44. Reinstall the fuel cap, making
sure to fully install the cap. SeeFilling the Tank
on page 5-6. 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 and message off.
TRACTION ACTIVE
When the traction control system has detected that
any of the vehicle’s wheels are slipping, the traction
control system will activate and this message will appear
on the DIC. SeeStabiliTrak
®System on page 4-9for
more information.
TRACTION SYS (System) LIMITED
If the brake traction control system activates constantly
or if the brakes have heated up due to high-speed
braking, brake traction control will be disabled and the
TRACTION SYS LIMITED message will be displayed.
The system will return to normal operation after the
brakes have cooled. SeeStabiliTrak
®System on
page 4-9for more information.
3-61

Anti-Lock Brake System (ABS)
Your vehicle has the Anti-Lock Brake System (ABS),
an advanced electronic braking system that will
help prevent a braking skid.
When you start your engine and begin to drive away,
ABS will check itself. You may hear a momentary
motor or clicking noise while this test is going on.
This is normal.
If there is a problem with
ABS, this warning light will
stay on. SeeAnti-Lock
Brake System Warning
Light on page 3-40.
Along with ABS, your vehicle has a Dynamic Rear
Proportioning (DRP) system. If there is a DRP problem,
both the brake and ABS warning lights will come
on accompanied by a 10-second chime. The lights
and chime will come on each time the ignition is
turned on until the problem is repaired. See your
dealer for service.Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You
slam on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down.
If one of the wheels is about to stop rolling, the computer
will separately work the brakes at each front wheel
and at both rear wheels.
4-7

Once you are moving on the freeway, make certain
you allow a reasonable following distance. Expect
to move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your exit,
do not, under any circumstances, stop and back up.
Drive on to the next exit.
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 are ready. Try to be well rested. If you
must start when you are not fresh — such as after
a day’s work — do not plan to make too many miles
that rst 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 is ready to go. If it needs
service, have it done before starting out. Of course,
you will nd experienced and able service experts in
GM dealerships all across North America. They will 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?
Lamps:Are they all working? Are the lenses clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inated to
the recommended pressure?
Weather Forecasts:What is the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?
Maps:Do you have up-to-date maps?
