• Entering a paved road from a gravel road, or vice versa

Roll Stability Control™ (RSC威)
Roll Stability Control™ (RSC威) may help to maintain roll stability of the
vehicle during adverse maneuvers. RSC威 operates by detecting the
vehicle’s roll motion and the rate at which it changes and by applying the
brakes to one or more wheels individually.
During an event that activates the Roll Stability Control™ (RSC威), the
stability control light in the instrument cluster will flash.
Certain adverse driving maneuvers may activate the RSC威 system, which
include:
• Emergency lane-change
• Taking a turn too fast
• Quick maneuvering to avoid an accident, pedestrian or obstacle
The RSC威 system may be deactivated in certain situations. See the
Switching off AdvanceTrac威 with RSC威 section following.
Switching off AdvanceTrac威 with RSC威
If the vehicle is stuck in snow, mud or sand, and seems to lose engine
power, switching off certain features of the AdvanceTrac威 with RSC威
system may be beneficial because the wheels are allowed to spin. This
will restore full engine power and will enhance momentum through the
obstacle.
To switch off the AdvanceTrac威 with
RSC威 system, press the stability
control button. Full features of the
AdvanceTrac威 with RSC威 system
can be restored by pressing the
stability control button again or by
turning off and restarting the
engine.
