Driving
vehicle is traveling in R (Reverse). In R (Reverse), ABS and the traction
enhancement feature will continue to function.
The AdvanceTrac with RSC button
allows the driver to control the
availability of the AdvanceTrac
with RSC system. AdvanceTrac
with RSC 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.
The AdvanceTrac with RSC system warning indicator light may flash to
indicate the system is not fully initialized. If this happens, slow down. If
the light continues flashing, have the AdvanceTrac with RSC system
serviced by an authorized dealer.
If a failure is detected in the AdvanceTrac with RSC system, the
warning indicator light in the instrument cluster will stay on and the
instrument cluster will chime repeatedly. If the warning indicator light in
the instrument cluster remains on and the chime is active while the
engine is running, have the system serviced by an authorized dealer
immediately.
Pressing the control will disable the AdvanceTrac with RSC system and
the traction enhancement feature at and below 20 mph (32 km/h). If the
vehicle is stuck in snow or mud or when driving in deep sand, switching
off the AdvanceTrac with RSC system may be 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 and the vehicle speed is 20 mph
(32 km/h) or below, switching off the AdvanceTrac with RSC stability
enhancement feature will restore full engine power and will enhance
momentum through the obstacle.
Note: The AdvanceTrac with RSC system will automatically restore to
full functionality every time the vehicle speed exceeds 20 mph (32 km/h)
or the ignition is turned off and back on. However, the AdvanceTrac
with RSC button remains illuminated even above 20 mph (32 km/h) until
it is pressed.
Some drivers may notice a slight movement of the brake pedal when the
AdvanceTrac with RSC performs a system self-check. During
AdvanceTrac with RSC operation you may experience the following:
• A rumble or grinding noise
• A slight deceleration of the vehicle
