This is especially usefulin slippery road conditions. On arear-wheel-drive vehicle, the systemoperates if it senses that one orboth of the rear wheels are spinningor beginning to lose traction. On anall—wheel—drive 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.TCS is on whenever the vehicleis started. To limit wheel spin,especially in slippery roadconditions, the system shouldalways be left on. But, TCS can beturned off if needed.TCS/StabiliTrak Lightd flashes to indicate that the TCS isactive.If there is a problem detected withTCS, a message may be displayedon the Driver Information Center(DIC).
