When the system is turned off, the traction off light will

illuminate, and the STABILITY SYS DISABLED

message will appear on the DIC to warn the driver that

both the stability system and part of the traction

control system are disabled. Your vehicle will still have

brake-traction control when StabiliTrak

is off, but

will not be able to use the engine speed management

system. See “Traction Control Operation” next for

more information.

When the StabiliTrak

system has been turned off,

you may still hear system noises as a result of

the brake-traction control coming on.

It is recommended to leave the system on for normal

driving conditions, but it may be necessary to turn the

system off if your vehicle is stuck in sand, mud, ice or

snow, and you want to “rock” your vehicle to attempt to

free it. It may also be necessary to turn off the system

when driving in extreme off-road conditions where high

wheel spin is required. See If Your Vehicle is Stuck in

Sand, Mud, Ice or Snow on page 4-46.

When the transfer case is in 4LO, the stability system is

automatically disabled, and the STABILITY SYS

DISABLED message will appear on the DIC. In 4LO,

the StabiliTrak

button only turns the traction control

system on and off.

Traction Control Operation

The traction control system is part of the StabiliTrak

system. Traction control limits wheel spin by reducing

engine power to the wheels (engine speed

management) and by applying brakes to each individual

wheel (brake-traction control) as necessary.

The traction control system is enabled automatically

when you start your vehicle, and it will activate and

display the TRACTION ACTIVE message in the Driver

Information Center (DIC) if it senses that any of the

wheels are spinning or beginning to lose traction while

driving. If you turn off StabiliTrak

, only the brake-traction

control portion of traction control will work. The engine

speed management will be disabled. In this state, engine

power is not reduced automatically and the driven wheels

can spin more freely. This can cause the brake-traction

control to activate constantly. For more information on the

traction active message, see Driver Information Center

(DIC) on page 3-51.

Notice: If the traction off light comes on due to

heavy braking and/or because the traction control

system has been continuously active, do not

allow the wheel(s) of one axle to spin excessively.

If you do, you may be causing damage to the

transfer case. This could lead to costly repairs not

covered by your warranty.
