Driving
Your vehicle may be equipped with the AdvanceTrac system. The
AdvanceTrac system provides the following stability enhancement
features for certain driving situations:
• Traction Control (TCS), which functions to help avoid drive-wheel
spin and loss of traction.
• Electronic Stability Control (ESC), which functions to help avoid skids
or lateral slides
The AdvanceTrac system automatically enables each time the engine is
started. All features of the AdvanceTrac system (TCS and ESC) are
active and monitor the vehicle from start-up. However, the system will
only intervene if the driving situation requires it.
The AdvanceTrac system includes an
AdvanceTrac Off button on the
center of the instrument panel, and a
"sliding car" icon in the instrument
cluster. The "sliding car" icon
the instrument cluster will illuminate
temporarily during start-up as part of a normal system self-check, or during
driving if a driving situation causes the AdvanceTrac system to operate. If
the "sliding car" icon
system is not manually disabled by pressing the AdvanceTrac
located on the center stack of the instrument panel. If the "sliding car"
icon remains steadily illuminated, have the system serviced by an
authorized dealer immediately. If equipped with a message center, the
vehicle will also indicate a failure with the AdvanceTrac system.
When AdvanceTrac performs a normal system self-check, some drivers
may notice a slight movement of the brake, and/or a rumble, grunting, or
grinding noise after startup and when driving off.
When an event occurs that activates AdvanceTrac you may experience
the following:
• A slight deceleration of the vehicle
• The "sliding car"
• A vibration in the pedal when your foot is on the brake pedal
• If the driving condition is severe and your foot is not on the brake, the
brake pedal may move as the systems applies higher brake forces. You
may also hear a whoosh of air from under the instrument panel during
this severe condition.
• The brake pedal may feel stiffer than usual.
