Driving
WARNING: If a failure has been detected within the
AdvanceTrac with RSC system, the stability control light will
illuminate steadily. Verify that the AdvanceTrac with RSC system is
not manually disabled (press the stability control button located on the
center of the instrument panel). If the stability control light still
illuminates steadily, have the system serviced by an authorized dealer
immediately. Operating your vehicle with AdvanceTrac with RSC
disabled could lead to an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death.
The AdvanceTrac with RSC system automatically enables each time
the engine is started. All features of the AdvanceTrac with RSC system
(TCS, ESC, and RSC ) are active and monitor the vehicle from start-up.
However, the system will only intervene if the driving situation requires
it.
The AdvanceTrac with RSC
system includes a traction control
button on the center of the
instrument panel, and a stability
control light in the instrument
cluster. The stability control light in
the instrument cluster will illuminate if a driving situation causes the
AdvanceTrac with RSC system to operate. If the stability control light
illuminates steadily, verify that the AdvanceTrac with RSC system is
not manually disabled by pressing the traction control button located on
the center stack of the instrument panel. If the stability control light
remains steadily illuminated, have the system serviced by an authorized
dealer immediately.
Note: If the system cannot be turned off, refer to MyKey™ in the Locks
and Security chapter for more information.
When AdvanceTrac with RSC performs a normal system self-check,
some drivers may notice a slight movement of the brake, and/or a
rumble, grunting, or grinding noise after startup and when driving off.
When an event occurs that activates AdvanceTrac with RSC you may
experience the following:
• A slight deceleration of the vehicle
• The stability control light will flash.
• A vibration in the pedal when your foot is on the brake pedal
