The Traction Control System (TCS)/StabiliTrak warning light should come on briefly when the engine is started. If it does not, have the vehicle serviced by your dealer/retailer. If the system is working normally the indicator light then goes off. If the light comes on or stays on while driving, there may be a problem with the TCS/StabiliTrak and the vehicle may need service. When this warning light is on, the system does not limit wheel spin. Adjust driving accordingly.
