07 05.22 Active traction control system (four −wheel drive models) The brake pad or actuator temperature increases during continuous operation of the traction control system or vehicle stability control system such as on slippery roads. If the brake pad or actuator temperature becomes too high while the traction control system or vehicle stability control system is operating, a buzzer will start to sound intermittently to indicate that the traction control system can no longer operate. In this case, stop your vehicle immediately at a safe place. If the system continues to operate, the buzzer sound changes from intermittent to continuous. (The continuous buzzer sounds for about 3 seconds.) At the time the "VSC TRAC" warning light will come on and the traction control system temporarily stops operating in order to protect the brake pad. (Although the traction control system does not operate, there is no problem to continue your driving.) The system will be automatically restored after a short time and the warning light goes out. If the light comes on while driving, the traction control system does not work. However, as conventional braking operates when applied, there is no problem to continue your driving. In the following cases, contact your Toyota dealer: The active traction control system automatically helps prevent the spinning of 4 wheels (4WD mode) or rear wheels (2WD mode) when the vehicle is started or accelerated on slippery road surfaces. When the ignition key is turned to "ON", the system automatically turns on. D The warning light does not come on after the ignition key is turned to "ON". D The warning light remains on after the ignition key is turned to "ON". D The warning light comes on while driving. The "TRAC OFF" indicator light will come on when the "VSC TRAC" warning light comes on even if the "TRAC OFF" switch is not pushed. CAUTION Under certain slippery road conditions, full traction of the vehicle and power against 4 wheels (4WD mode) or rear wheels (2WD mode) cannot be maintained, even though the active traction control system is in operation. Do not drive the vehicle under any speed or maneuvering conditions which may cause the vehicle to lose traction control. In situations where the road surface is covered with ice or snow, your vehicle should be fitted with snow tires or tire chains. Always drive at an appropriate and cautious speed for the present road conditions. 186 2007 SEQUOIA from Aug. '07 Prod. (OM34462U)
