Driving
If the parking brake fails to release
after completing this procedure, use
the manual parking brake release
lever.
Pull the release lever to release the
brake. Driving with the parking
brake on will cause the brakes to
wear out quickly and reduce fuel
economy.
ADVANCETRAC WITH ROLL STABILITY CONTROL (RSC)
STABILITY ENHANCEMENT SYSTEM (IF EQUIPPED)
AdvanceTrac with RSC is an integrated system with four major
components: Anti-lock Brake System (ABS), Traction Control, yaw
control and a vehicle-roll motion sensor. It automatically utilizes these
elements in varying combinations to help give the driver optimum control
at all times. AdvanceTrac , which includes ABS, Traction Control and
yaw control, helps your vehicle maintain traction when driving on
slippery and/or hilly road surfaces, by detecting and controlling wheel
spin. Excessive wheel spin is controlled by momentarily reducing engine
power and rapidly applying the anti-lock brakes. The system is a driver
aid which makes your vehicle easier to handle primarily on snow and
ice-covered roads. RSC detects potential rollover type situations and
quickly engages AdvanceTrac to help keep your tires firmly planted on
the ground.
If your vehicle should become stuck in deep snow or mud, try switching
the AdvanceTrac with RSC system off by pressing the AdvanceTrac
with RSC button located on the center console. This will allow your tires
to "dig" for traction.
If the AdvanceTrac with RSC system is activated and deactivated
excessively in a short period of time, the brake portion of the system will
shut down to allow the brakes to cool down. A limited AdvanceTrac
with RSC function using only engine power reduction will still help
control the wheels from over-spinning. When the brakes have cooled
down, the system will again function normally. Anti-lock braking is not
affected by this condition and will function normally during the
cool-down period.
The AdvanceTrac with RSC system enhances your vehicle's stability
during maneuvers that require all available tire traction, like in
wet/snowy/icy road conditions and/or when performing emergency
