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
AdvanceTrac威 with RSC威⬙Off⬙ button. Full features of the AdvanceTrac威
with RSC威 system can be restored by pressing the AdvanceTrac威 with
RSC威⬙Off⬙ button again or by turning off and restarting the engine.
If you switch off the AdvanceTrac威 with RSC威 system, the AdvanceTrac
with RSC威 “Off” button will illuminate and the sliding car⬙ icon
will
illuminate steadily. Pressing the AdvanceTrac威 with RSC威⬙Off⬙ button
again will turn off the lighted button and the ⬙sliding car⬙ icon
.
In R (Reverse), ABS and the Engine and Brake Traction Control features
will continue to function; however, ESC and RSC威 are disabled.

STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to decrease the driver’s effort in steering the vehicle.
To help prevent damage to the power steering pump:
• Never hold the steering wheel to the extreme right or the extreme left
for more than a few seconds when the engine is running.
