Traction Control System (TCS) If the vehicle has the 3800 Supercharged V6 engine or the 5.3L V8 engine, it has a Traction Control System (TCS) that limits wheel spin. This is especially useful in slippery road conditions. The system operates only if it senses that one or both of the front wheels are spinning or beginning to lose traction. When this happens, the system works the front brakes and reduces engine power to limit wheel spin. This symbol, along with the TRACTION CONTROL ACTIVE message, comes on the DIC screen when the system is active. When the traction control system is not working, one of these symbols will come on the instrument panel cluster. This symbol is located on the instrument panel cluster. You may feel or hear the system working, but this is normal. This symbol, along with the message TRACTION CONTROL OFF will display in the DIC for three seconds when the traction control system is disabled. 292
