Traction Control System (TCS) Your vehicle has a traction control system called TCS that limits wheel spin. Thisis especially useful in slippery road conditions. The system operates only if it senses that the rear wheels are spinning too much or are beginning to lose traction. When this happens, the system works the rear brakes and reduces engine power (by closing the throttle and managing engine spark) to limit wheel spin. The TRACTION SYS ACTIVE message will come on when the TCS system is limiting wheel spin. See DIC Warnings and Messages on page 3-53. You may feel or hear the system working, but this is normal. If your vehicle is in cruise control when the TCS system begins to limit wheel spin, the cruise control will automatically disengage. When road conditions allow you to safely use it again, you may re-engage the cruise control. See Turn SignaVMultifunction Lever on nane 3-6 - ~-a I- ' D i The SERVICE TRACTION SYSTEM message and the TCS warning light will come on to let you know if there's a problem with your TCS system. See DIC Warnings and Messages on page 3-51. When this light and the SERVICE TRACTION SYSTEM message are on, the system will not limit wheel spin. Adjust your driving accordingly. The TCS system automatically comes on whenever you start your vehicle. To limit wheel spin, especially in slippery road conditions, you should always leave the system on. But you can turn the TCS system off if vou ever need to. 4-9
