Driving
WARNING: If a failure has been detected within the
AdvanceTrac with RSC system, the stability control light and
stability control off light will illuminate steadily. Verify that the
AdvanceTrac with RSC system is not manually disabled. Select
traction control off in the message center. If the stability control and
stability control off lights still illuminate 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, RSC and Curve Control) 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
off selection in the message center.
The stability control light and
stability control off light in the instrument cluster will illuminate
temporarily during start-up as part of a normal system self-check, or
during driving if a driving situation causes the AdvanceTrac with RSC
system to operate. If the stability control light and stability control off
light remain steadily illuminated, have the system serviced by an
authorized dealer immediately. The message center will also indicate a
failure with the brake system.
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 deceleration of the vehicle
• The stability control light will flash.
• A vibration in the pedal when your foot is on the brake pedal
• If the driving condition is severe and your foot is not on the brake, the
brake pedal may move as the systems applies higher brake forces. You
may also hear a whoosh of air from under the instrument panel during
this severe condition.
• The brake pedal may feel stiffer than usual.
• Engine power may be reduced.
