03_SEQUOIA_U (L/O 0301) The traction control system will automatically go on, and the "TRAC OFF" indicator light will go off when you drive over 30 km/h (19 mph) even if the "TRAC OFF" switch is pushed to cancel the traction control system. "TRAC OFF" indicator light comes on for a few seconds when the ignition key is turned to "ON". It will come on again when you push the "TRAC OFF" switch to turn off the system. In the following cases, contact your Toyota dealer: The brake pad or actuator temperature increases during continuous operation of the traction control system or vehicle skid control system such as on slippery roads. If the brake pad or 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, 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. D The indicator light does not come on when the ignition key is turned "ON". "VSC/TRAC" warning light This light warns that there is a problem somewhere in the traction control system or the vehicle skid control system. The warning light will come on when the ignition key is turned to "ON" and will go off after a few seconds. D The indicator light remains on after the ignition is turned on. D The indicator light comes on with the normal driving mode while driving. 153 2003 SEQUOIA from Jan. '03 Prod. (OM34422U)
