06 06.07 The slip indicator light and downhill assist control system indicator light come on for a few seconds when the ignition key is turned to "ON". If any of the indicator lights does not come on when the ignition is turned on, contact your Toyota dealer. The brake actuator temperature increases during continuous operation of the hill− start assist control system, the active traction control system and the vehicle stability control system. If the brake actuator temperature becomes too high while any of the systems is operating, a buzzer will start to sound intermittently to indicate that the downhill assist 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 this time, the slip indicator light will come on, the downhill assist control system indicator light flash and the downhill assist control system stops operating temporarily in order to protect the brake actuator. (Although the downhill assist control system does not operate, it is no problem to continue your driving.) The system will be automatically restored after a short time and the slip indicator light and the downhill assist control system indicator light go out.
