STARTING AND DRIVING TRACTION CONTROL SYSTEM (Vehicles with automatic transmission only) The traction control system automatically controls spinning of the rear wheels which may occur when accelerating on slippery road surfaces, thus assisting driver control and driving power to the rear wheels. When you turn the ignition switch on, this system always turns on. Leave the system on during ordinary driving so that it can operate when needed. When traction control is applied, the "TRAC" indicator/warning light blinks. You may hear a slight clicking noise in the engine compartment when the engine is started. This means that the traction control system is in the self-check mode, and does not indicate malfunction. When the traction control system is operating, you may feel vibration of your vehicle, caused by operation of the brakes. This indicates the system is functioning properly. When getting the vehicle out of mud or new snow, etc. the traction control system will help operate to prevent the wheels from spinning. Even though the accelerator pedal is fully depressed, the engine speed will be restrained to a certain level. Traction control failure warning If the "TRAC OFF" indicator/warning light flashes, contact your Lexus dealer as soon as possible. There may be trouble in the traction control system. ! CAUTION You can turn off the traction control system by pushing the "TRAC-OFF-" switch. The "TRAC OFF" indicator/warning light will then come on. Pushing the "TRAC-OFF-" switch a second time turns the system back on and extinguishes the "TRAC OFF" indicator/warning light. Under certain slippery road conditions, full stability of the vehicle and power to the rear wheels cannot be maintained, even though the traction control system is in operation. In situations where the road surface is covered with ice or snow, your vehicle should be fitted with snow tires or tire chains and driven at a more cautious pace. 128
