Traction Control System (TCS) The vehicle 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 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. This light will flash when the traction control system is limiting wheel spin. When this light is on solid and either the SERVICE TRACTION or TRACTION OFF message is displayed, the system will not limit wheel spin. Adjust your driving accordingly. See DIC Warnings and Messages on page 3-37 for more information. The Traction Control System is automatically enabled whenever the vehicle is started. To limit wheel spin, especially in slippery road conditions, always leave the system enabled. TCS can be turned off if needed. It is recommended to leave the system on for normal driving conditions, but it may be necessary to turn the system off if the vehicle is stuck in sand, mud, ice or snow, and you want to "rock" the vehicle to attempt to free it. It may also be necessary to turn off the system when driving in extreme off-road conditions where high wheel spin is required. See If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on page 4-19. The system may be heard or felt while it is working, but this is normal. If the vehicle is in cruise control when TCS begins to limit wheel spin, the ESC/TCS light will flash and the cruise control will automatically disengage. The cruise control may be reengaged when road conditions allow. See Cruise Control on page 3-9. 4-8
