AdvanceTrac娂 enhances your vehicle’s stability during maneuvers that

require all available tire traction, like in wet/snowy/icy road conditions

and/or when performing emergency maneuvers. In an emergency

lane-change, the driver will experience better overall vehicle traction,

and have better control of the vehicle.

The AdvanceTrac娂 system helps the driver maintain steering control if

the vehicle begins to slide excessively left or right or spin out.

AdvanceTrac娂 will attempt to correct the sliding motion by applying

brake force at individual tires and, if necessary, by reducing engine

power.

Driving conditions which may activate AdvanceTrac娂 include:

• Taking a turn too fast

• Maneuvering quickly to avoid an accident, pedestrian or obstacle

• Hitting a patch of ice

• Changing lanes on a snow-rutted road

• Entering a snow-free road from a snow-covered side street, or vice

versa

• Entering a paved road from a gravel road, or vice versa

• Hitting a curb while turning

• Driving on slick surfaces

• Cornering while towing a heavily loaded trailer (refer to Trailer

Towing in this chapter)

The AdvanceTrac娂 system automatically turns on when the engine is

started. However, the system does not function when the vehicle is

traveling in R (Reverse) or, if equipped with four-wheel drive, in 4L (4X4

LOW). In R (Reverse) or in 4L (4X4 LOW), ABS and the traction

enhancement feature will continue to function.

The AdvanceTrac娂 button allows

the driver to control the availability

of the AdvanceTrac娂 system.

AdvanceTrac娂 system status is

indicated by a warning indicator

light with a “sliding car” icon in the

instrument cluster that will flash when the system is activated and an

indicator light in the control button that will illuminate when the system

is turned off.

If a failure is detected in the AdvanceTrac娂 system, the warning

indicator light in the instrument cluster will stay on. If the warning
