Traction control and StabiliTrak

can be turned on by

pressing and releasing the StabiliTrak

button if

not automatically shut off for any other reason.

When the TCS or StabiliTrak

system is turned off, the

StabiliTrak

light and the appropriate TCS off or

StabiliTrak

off message will be displayed on the DIC to

warn the driver. Your vehicle will still have brake-traction

control when traction control is off, but will not be

able to use the engine speed management system. See

“Traction Control Operation” next for more information.

When the traction control 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 4-33.

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

automatically disabled, the StabiliTrak

light will come

on and the STABILITRAK OFF message will appear on

the DIC. Both traction control and StabiliTrak

are

automatically disabled in this condition.

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. It will activate and the

StabiliTrak

light will ﬂash if it senses that any of the

wheels are spinning or beginning to lose traction while

driving. If you turn off traction control, only the

brake-traction control portion of traction control will

work. The engine speed management will be disabled.

In this mode, engine power is not reduced automatically

and the driven wheels can spin more freely. This can

cause the brake-traction control to activate constantly.

Notice: If you allow the wheel(s) of one axle to spin

excessively while the StabiliTrak

, ABS and brake

warning lights and the SERVICE STABILITRAK

message are displayed, you could damage the

transfer case. The repairs would not be covered by

your warranty. Reduce engine power and do not

spin the wheel(s) excessively while these lights and

this message are displayed.
