when the system is active and an indicator light in the control button
that will illuminate when the system is turned off. In vehicles with a
message center, the message “ADVANCETRAC OFF” will be displayed.
If a failure is detected in the AdvanceTrac system, the warning
indicator light in the instrument cluster will stay on. If the warning
indicator light in the instrument cluster remains on while the engine is
running, have the system serviced immediately.
Some drivers may notice a slight movement of the brake pedal when the
AdvanceTrac performs a system self-check. During AdvanceTrac
operation you may experience the following:
• A rumble or grinding noise
• A slight deceleration of the vehicle
• The AdvanceTrac 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 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 system. Also, do not install a stereo
loudspeaker near the rear console or either rear 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 a Traction Control
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.
