If cruise control is being used when StabiliTrak activates, the cruise control automatically disengages. The cruise control can be re-engaged when road conditions allow. See Cruise Control on page 3-10. If there is a problem detected with StabiliTrak, a SERVICE STAB SYS message displays on the Driver Information Center (DIC). See DIC Warnings and Messages on page 3-38 for more information. When this message is displayed, the system is not working. Adjust your driving accordingly. StabiliTrak and Traction Control (TCS) come on automatically whenever the vehicle is started and the systems are reset with each ignition cycle. However, when the transfer case is placed in Four-Wheel-Low mode, StabiliTrak is automatically disabled. See Four-Wheel Drive on page 2-26 for more information. It is recommended to leave the system on for normal driving conditions, but it may be necessary to turn the TCS portion of the system off if the vehicle is stuck in sand, mud, ice, or snow, and it is necessary to "rock" the vehicle to attempt to free it. If traction control is turned off, 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 drive wheels can spin more freely. This can cause the brake-traction control to activate constantly. See If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on page 4-31. The StabiliTrak/TCS light will flash on the instrument panel cluster when the TCS system or StabiliTrak is both on and activated. The StabiliTrak/TCS button is located on the instrument panel. 4-7
