The vehicle has a Traction Control System (TCS) that limits wheel spin.
On a front-wheel-drive vehicle, the system operates if it senses that one or both of the front wheels are spinning or beginning to lose traction. When this happens, the system brakes the spinning wheel(s), and/or reduces engine power to limit wheel spin.
The system may be heard or felt while it is working, but this is normal.
TCS is on whenever the vehicle is started. To limit wheel spin, especially in slippery road conditions, the system should always be left on. But, TCS can be turned off if needed.

control system is active.
If there is a problem detected with TCS, SERVICE TRACTION CONTROL and SERVICE STABILITRAK may be displayed on the Driver Information Center (DIC).
When this message is displayed and d comes on and stays on, the vehicle is safe to drive but the system is not operational.
Driving should be adjusted accordingly.

system:

2. Turn the engine off and wait 15 seconds.
