On anAll-Wheel-Drive (AWD) vehicle, thesystem will operate if it senses thatany of the wheels are spinning orbeginning to lose traction. When thishappens, the system brakes thespinning wheel(s) and/or reducesengine power to limit wheel spin.The system may be heard or feltwhile it is working, but this isnormal.The TCS/StabiliTrak warning lightflashes when the traction controlsystem is limiting wheel spin.The TCS/StabiliTrak warning lightcomes on if there is a problem withthe traction control system. Whenthe TCS/StabiliTrak warning light ison, the system will not limit wheelspin. Adjust your drivingaccordingly. See Traction ControlSystem (TCS)/StabiliTrak ® Light onpage 5‑24 for more information.TCS automatically comes onwhenever the vehicle is started.
