01_SEQUOIA_U (L/O 0009) Active traction control system (four −wheel drive models) The brake actuator temperature increases during continuous operation of the traction control system or vehicle skid control system such as on slippery roads. If the brake actuator temperature becomes too high while the traction control system or vehicle skid 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, immediately stop your vehicle 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 actuator. (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 "VSC/TRAC" warning light goes out. When the "VSC/TRAC" warning light and "TRAC OFF" indicator light come on the traction control system does not operate, but there is no problem to continue your driving. In the following cases, contact your Toyota dealer: D The "VSC/TRAC" warning light and "TRAC OFF" indicator light do not come on after the ignition is turned on. D The "VSC/TRAC" warning light and "TRAC OFF" indicator light are left on after the ignition is turned on. CAUTION Under certain slippery road conditions, full traction of the vehicles and power to rear wheels cannot be maintained, even though the traction control system is in operation. Do not drive the vehicle under any speed or maneuvering conditions which will cause the vehicle to lose traction. 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 road conditions present. The active traction control system automatically helps control the spinning of 4 wheels (4WD mode) or rear wheels (2WD mode) which may occur when accelerating on slippery road surfaces, by controlling the output of the brake and engine. Thus, the system assists driver to control the driving power of 4 wheels (4WD mode) or rear wheels (2WD mode). When you turn the ignition switch on, the active traction control system always turns on automatically, and the slip indicator light will come on. The indicator lights will go off after about a few seconds. 142 2001 SEQUOIA (OM34414U)
