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.
