08 02.19 The slip indicator light and downhill assist control system indicator light come on for a few seconds when the engine switch is turned to "ON". If any of the indicator lights does not come on when the engine switch is turned on, contact your Toyota dealer. If the system is used frequently, the brake actuator temperature may become too high and a buzzer will sound intermittently. If this happens, the downhill assist control system indicator light will flash and a buzzer will sound intermittently. When the temperature of the brake actuator decreases, the system will begin to operate again. Until it restarts, the traction control system and hill −start assist control system will not operate; however, the conventional brake can be operated. The brake actuator temperature increases during continuous operation of the following systems under conditions such as on slippery roads. 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 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 goes out. LS17010 If there is any abnormality in the system, the "VSC OFF" warning light will flash. When the "DAC" switch is pushed, the downhill assist control system indicator light also flash. If the "VSC OFF" warning light flashes, there may be an abnormality in any of the following system in addition to the downhill assist control system.
