Driving and Operating 9-37The TCS/StabiliTrak button islocated on the instrument panel.The traction control part ofStabiliTrak can be turned off bypressing and releasing the TCS/StabiliTrak button if both systems(traction control and StabiliTrak)were previously on.To disable both TCS andStabiliTrak, press and hold the TCS/StabiliTrak button until theStabiliTrak OFF light illuminates andthe appropriate DIC messagedisplays. This will also disable theTSC feature.Traction control and StabiliTrak canbe turned on by pressing andreleasing the TCS/StabiliTrak buttonif they are not automatically shut offfor any other reason. This will alsoenable the TSC feature.When the TCS or StabiliTrak systemis turned off, the StabiliTrak lightand the appropriate message will bedisplayed on the DIC to warn thedriver. The vehicle will still havebrake-traction control when tractioncontrol is off, but will not be able touse the engine speed managementsystem. See “Traction ControlOperation” next for moreinformation.When the TCS has been turned off,system noises may still be heard asa result of the brake-traction controlcoming on.It is recommended to leave thesystem on for normal drivingconditions, but it may be necessaryto turn the system off if the vehicleis stuck in sand, mud, ice or snow,and you want to “rock” the vehicle toattempt to free it. It may also benecessary to turn off the systemwhen driving in extreme off-roadconditions where high wheel spin isrequired. See If the Vehicle Is Stuckon page 9‑13.Traction Control OperationThe TCS is part of the StabiliTraksystem. Traction control limits wheelspin by reducing engine power tothe wheels (engine speedmanagement) and by applyingbrakes to each individual wheel(brake-traction control) asnecessary.The TCS is enabled automaticallywhen the vehicle is started. It willactivate and the StabiliTrak light willflash if it senses that any of thewheels are spinning or beginning tolose traction while driving. If tractioncontrol is turned off, only thebrake-traction control portion oftraction control will work. The
