Magnetic Ride Control
Magnetic Ride Control automatically adjusts the
ride of your vehicle. Automatic ride control is
achieved through a computer used to control and
monitor the suspension system. The controller
receives input from various sensors to determine
the proper system response. If the controller
detects a problem within the system, the DIC will
display a SERVICE RIDE CONTROL message.
SeeDIC Warnings and Messages on page 206for
more information. See your dealer for service.
Limited-Slip Rear Axle
Your limited-slip rear axle can give you additional
traction on snow, mud, ice, sand or gravel. It
works like a standard axle most of the time, but
when one of the rear wheels has no traction
and the other does, this feature will allow
the wheel with traction to move the vehicle.
StabiliTrak®System
The StabiliTrak®System is a 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.
When you rst start your vehicle and begin to
drive away (6 mph (10 km/h)), especially during
cold weather, the message STABILITRAK
WARMING may be displayed in the Driver
Information Center (DIC), the instrument panel
cluster light will be on, and a chime will sound.
This is normal. You can acknowledge this
message by pressing the RESET button. The
StabiliTrak
®System performance is affected until
the message, STABILITRAK READY, is
displayed in the DIC. This can take up to
15 minutes.
The WAIT FOR STABILITRAK message may be
displayed in the DIC after exceeding 19 mph
(30 km/h) for 10 seconds if the steering is
not centered. The system is off until the
STABILITRAK ACTIVE message is displayed.
331
The STABILITRAK ACTIVE message will come on
when the system is operating. SeeDIC Warnings
and Messages on page 206for more information.
You may also feel or hear the system working.
This is normal.
The instrument panel
cluster light will come
on and a chime will
sound to let you know if
there is a problem
with the system.
The SERVICE STABILITRAK message will also
be displayed. SeeDIC Warnings and Messages on
page 206for more information.
When this light and the SERVICE STABILITRAK
message are on, the system is not operational.
Adjust your driving accordingly.
The system comes on automatically whenever you
start your vehicle. To help maintain directional
control of the vehicle, you should always leave the
system on. You can turn the system off if youever need to. If you turn the StabiliTrak®system
off, the Traction Control System will also be turned
off. Adjust your driving accordingly.
To turn the system off,
press and hold the front
part of the traction
control button on the
console for ve seconds
with the vehicle
stopped.
You can turn the system back on at any time by
pressing the button. The DIC will display the
appropriate message when you push the button,
either TRAC/STABILITRAK ON or
TRAC/STABILITRAK OFF.

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?
