Traction Control System (TCS)
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. On an All-Wheel-Drive (AWD) vehicle, the system will operate if it senses that any of the 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.

It may be necessary to turn the system off if the vehicle ever gets stuck in sand, mud, or snow and rocking the vehicle is required. See If the Vehicle Is Stuck on page 9‑15 for more information.
