DRIVING AND OPERATING 201Ride Control SystemsTraction Control/ElectronicStability ControlThe vehicle has a Traction ControlSystem (TCS) and StabiliTrak/Electronic Stability Control (ESC).These systems help limit wheel slipand assist the driver in maintainingcontrol, especially on slippery roadconditions.TCS activates if it senses that any ofthe drive wheels are spinning orbeginning to lose traction. When thishappens, the system brakes thespinning wheel(s) and/or reducesengine power to limit wheel spin.StabiliTrak/ESC activates when thecomputer senses a difference betweenthe intended path and the directionthe vehicle is actually traveling.StabiliTrak/ESC selectively appliesbraking pressure at any one of thevehicle's brakes to help steer thevehicle in the intended direction.If cruise control is being used and TCSor StabiliTrak/ESC begins to limitwheel spin, cruise control willdisengage. Cruise control may beturned back on when road conditionsallow.Both systems come on automaticallywhen the vehicle is started and beginsto move. The systems may be heard orfelt while they are operating or whileperforming diagnostic checks. This isnormal and does not mean there is aproblem with the vehicle.It is recommended to leave bothsystems on for normal drivingconditions, but It may be necessary toturn TCS off if the vehicle gets stuckin sand, mud, ice, or snow. See If theVehicle Is Stuck 0 183 and “Turningthe Systems Off and On” later in thissection.The indicator light for both systems isin the instrument cluster. Thislight will:. Flash when TCS is limitingwheel spin.. Flash when StabiliTrak/ESC isactivated.. Turn on and stay on when eithersystem is not working.If either system fails to turn on or toactivate, a message may display in theDriver Information Center (DIC), andd comes on and stays on to indicatethat the system is inactive and is notassisting the driver in maintainingcontrol. The vehicle is safe to drive,but driving should be adjustedaccordingly.If d comes on and stays on:1. Stop the vehicle.2. Turn the engine off and wait15 seconds.3. Start the engine.
