• A slight deceleration of the vehicle
• The TRAC ACTIVE indicator light will illuminate
• 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 operation.
If the AdvaceTrac system is activated for an extended period of time, the
brake portion of the system will shut down to allow the brakes to cool
down. A limited AdvanceTrac function using only engine power
reduction will still help control the wheels from over-spinning. When the
brakes have cooled down, the system will again function normally.
Anti-lock braking is not affected by this condition and will function
normally during the cool-down period.
Do not alter or modify your vehicle's suspension or steering; the
resulting changes to the vehicle's handling can adversely affect
the AdvanceTrac 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 sensors located in this area.
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 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
To 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 reservoir
fluid level (below the MIN mark on the reservoir).
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
