are allowed to spin. If your vehicle seems to lose engine power while

driving in deep sand or very deep snow, switching off the AdvanceTrac娂

stability enhancement feature will restore full engine power and will

enhance momentum through the obstacle.

Some drivers may notice a slight movement of the brake pedal when the

AdvanceTrac娂 performs a system self-check. During AdvanceTrac娂

operation you may experience the following:

• A rumble or grinding noise

• 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娂 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娂 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娂 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.
