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. Remember to switch the AdvanceTrac
with RSC system back on once the vehicle is no longer stuck.
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
• Steering feedback
• The AdvanceTrac with RSC indicator light will flash
• If your foot is on the brake pedal, you will feel a vibration in the
pedal.
All these conditions are normal during AdvanceTrac
with RSC
operation.
Do not alter or modify your vehicle’s suspension, steering or
tires; the resulting changes to the vehicle’s handling can
adversely affect the AdvanceTrac
with RSC system. Also, do not
install a stereo loudspeaker. The speaker vibrations can adversely
affect the AdvanceTrac
with RSC sensors.
STEERING
To help prevent damage to the power steering system:
• Never hold the steering wheel at its furthest turning points (until it
stops) for more than a few seconds when the engine is running.
• Do not operate the vehicle with a low power steering pump fluid level
(If the fluid level is below the FULL COLD range on the dipstick).
• Some noise is normal during operation. If the noise is excessive, check
for low power steering pump fluid level before seeking service by your
authorized dealer.
