Roll Stability Control System (if equipped)
The Roll Stability Control system works in conjunction with the
AdvanceTrac system to further enhance the vehicle's overall stability
during aggressive maneuvers. The system helps maintain roll stability of
the vehicle during aggressive maneuvers by applying brake force to one
or more wheels.
Driving conditions that may activate Roll Stability Control include:
• Emergency lane-change
• Taking a turn too fast
• Quick maneuvering to avoid an accident, pedestrian or obstacle
The AdvanceTrac /Roll Stability Control system automatically turns on
when the engine is started. However, the system does not function when
the vehicle is traveling in R (Reverse). In R (Reverse), ABS and the
traction enhancement feature will continue to function.
The AdvanceTrac /Roll Stability
Control button allows the driver to
control the availability of the
AdvanceTrac /Roll Stability Control
system. AdvanceTrac /Roll Stability
Control system status is indicated by a warning indicator light with a
"sliding car" icon in the instrument cluster that will flash when the
system is active and an indicator light in the control button that will
illuminate when the system is turned off. In vehicles with a message
center, the message "ADVTRAC OFF" will be displayed.
If a failure is detected in the AdvanceTrac /Roll Stability Control
system, the warning indicator light in the instrument cluster will stay on.
If the warning indicator light in the instrument cluster remains on while
the engine is running, have the system serviced immediately.
Pressing the control once will disable the AdvanceTrac
enhancement/Roll Stability Control and the engine power reduction
portion of the traction enhancement feature; the brake portion of the
traction enhancement feature will still function normally. Pressing and
holding the control for more than five seconds will disable the
AdvanceTrac stability enhancement/Roll Stability Control and traction
enhancement feature. If the vehicle is stuck in snow or mud or when
driving in deep sand, switching off the AdvanceTrac
beneficial so the wheels are allowed to spin. If your vehicle seems to lose
engine power while driving in deep sand or very deep snow, switching off
the AdvanceTrac stability enhancement feature will restore full engine
power and will enhance momentum through the obstacle.
