Some drivers may notice a slight movement of the brake pedal when the
AdvanceTrac威 with RSC performs a system self-check. During
AdvanceTrac威 with RSC system operation you may experience the
following:
• A rumble or grinding noise
• A slight deceleration of the vehicle
• The AdvanceTrac威 with RSC indicator light will flash
• If your foot is on the brake pedal, you will feel a vibration in the
pedal.
• If the driving condition is severe and your foot is not on the brake, the
brake pedal will move to apply higher brake forces. You may also hear
a whoosh of air from under the instrument panel during this severe
condition.
All these conditions are normal during AdvanceTrac威 with RSC
operation.
Do not alter or modify your vehicle’s suspension or steering; the
resulting changes to the vehicle’s handling can adversely affect
the AdvanceTrac威 with Roll Stability Control娂 system. Also, do
not install a stereo loudspeaker near the front center console or
under either front seat. The speaker vibrations can adversely
affect the AdvanceTrac威 with Roll Stability Control娂 sensors
located in this area.
Note: Pressing the AdvanceTrac威 with RSC button will disable the
AdvanceTrac威 with RSC system.
Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. The occurrence of an AdvanceTrac威 with
Roll Stability Control娂 event is an indication that at least some of the
tires have exceeded their ability to grip the road; this may lead to an
increased risk of loss of vehicle control, vehicle rollover, personal injury
and death. If you experience a severe road event, SLOW DOWN.
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 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.
