Driving and Operating taken in for service. For more information on the DIC messages, see Ride Control System Messages on page 5‑40. The traction control part of StabiliTrak can be turned off by pressing and releasing the TCS/ StabiliTrak button if both systems (traction control and StabiliTrak) were previously on. 9-43 When the TCS or StabiliTrak system is turned off, the StabiliTrak light and the appropriate message will be displayed on the DIC to warn the driver. The 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 TCS has been turned off, system noises may still be heard 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 the vehicle is stuck in sand, mud, ice or snow, and you want to "rock" the 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 the Vehicle Is Stuck on page 9‑14. The StabiliTrak light will flash on the instrument panel cluster when the system or the TSC feature is both on and activated. The system may be heard or felt while it is working; this is normal. To disable both TCS and StabiliTrak, press and hold the TCS/ StabiliTrak button until the StabiliTrak OFF light illuminates and the appropriate DIC message displays. This will also disable the TSC feature. Traction control and StabiliTrak can be turned on by pressing and releasing the TCS/StabiliTrak button if they are not automatically shut off for any other reason. This will also enable the TSC feature. The TCS/StabiliTrak button is located on the instrument panel.
