Your vehicle has the StabiliTrak system which combines antilock brake, traction and stability control systems and helps the driver maintain directional control of the vehicle in most driving conditions.
When you ﬁrst start your vehicle and begin to drive away, the system performs several diagnostic checks to ensure there are no problems. You may hear or feel the system working. This is normal and does not mean there is a problem with your vehicle. The system should initialize before the vehicle reaches 20 mph (32 km/h).
In some cases, it may take approximately two miles of driving before the system initializes.
If the system fails to turn on or activate, the StabiliTrak light along with one of the following messages will be displayed on the Driver Information Center (DIC): TRACTION CONTROL OFF, SERVICE TRACTION CONTROL, SERVICE STABILITRAK. If you see these conditions, turn the vehicle off, wait 15 seconds, and then turn it back on again to reset the system. If any of these messages still appear on the Driver Information Center (DIC), your vehicle should be taken in for service. For more information on the DIC messages, see Driver Information Center (DIC) on page 3-54.
The StabiliTrak light will ﬂash on the instrument panel cluster when the system is both on and activated. You may also feel or hear the system working; this is normal. The traction control disable button is located on the instrument panel below the climate controls. The traction control part of StabiliTrak can be turned off by pressing and releasing the traction control disable button.
Traction control can be turned on by pressing and releasing the traction control disable button if not automatically shut off for any other reason.
When the traction control system is turned off, the StabiliTrak light and the appropriate traction control 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 4-21.
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.
The traction control system may activate on dry or rough roads or under conditions such as heavy acceleration while turning or abrupt upshifts/downshifts of the transmission. When this happens, you may notice a reduction in acceleration, or may hear a noise or vibration. This is normal.
If your vehicle is in cruise control when the system activates, the StabiliTrak light will ﬂash and the cruise control will automatically disengage. When road conditions allow you to use cruise again, you may re-engage the cruise control. See Cruise Control on page 3-12.
StabiliTrak may also turn off automatically if it determines that a problem exists with the system. If the problem does not clear itself after restarting the vehicle, you should see your dealer/retailer for service.
