enhancement feature; the brake portion of the traction enhancement
feature will still function normally. Pressing and holding the control for
more than five seconds will disable the AdvanceTrac
stability
enhancementandtraction enhancement feature. If the vehicle is stuck
in snow or mud or when driving in deep sand, switching off the
AdvanceTrac
system may be beneficial so the wheels 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
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
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 wheel/tire size, suspension
or steering; the resulting changes to the vehicle’s handling can
adversely affect the AdvanceTrac
system.
Modification/Addition of supplemental radio components, such as
a subwoofer, may adversely affect the performance of the
AdvanceTrac
system.
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.

Tires that are larger or smaller than your vehicle’s original tires may also
affect the accuracy of your speedometer.
SNOW TIRES AND CHAINS
Snow tires must be the same size and grade as the tires you
currently have on your vehicle.
The tires on your vehicle have all weather treads to provide traction in
rain and snow. However, in some climates, you may need to use snow
tires or chains.
Follow these guidelines when using snow tires and chains:
•Use only SAE Class S chains with P225/55R16 tires.
•Do not use tire chains with size P235/50R17 tires. Use of SAE Class S
chains or other chain types may damage your vehicle.
•Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
•Drive cautiously. If you hear the chains rub or bang against your
vehicle, stop and re-tighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.
•If possible, avoid fully loading your vehicle.
•Remove the tire chains when they are no longer needed. Do not use
tire chains on dry roads.
•The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from your vehicle when
using snow tires or chains.
