Roll Stability Control™ (RSC
)
Roll Stability Control™ (RSC
) may help to maintain roll stability of the
vehicle during adverse maneuvers. RSC
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
) the
stability control light in the instrument cluster will flash.
Certain adverse driving maneuvers may activate the Roll Stability
Control™ system, which include:
• Emergency lane-change
• Taking a turn too fast
• Quick maneuvering to avoid an accident, pedestrian or obstacle
The Roll Stability Control™ system may be deactivated in certain
situations. See the Switching off AdvanceTrac
with RSC section
following.
Switching off AdvanceTrac
with RSC
If the vehicle is stuck in snow, mud or sand, and seems to lose engine
power, switching off certain features of the AdvanceTrac
with RSC
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
with RSC system, press the
stability control button located on the instrument panel to the right of
the climate control system. Full features of the AdvanceTrac
with RSC
system can be restored by pressing the button again or by turning off
and restarting the engine.
