05 02.25 LS17007 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. 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. With the vehicle traveling at a speed of 25 km/h (15 mph) or less, release your foot from the accelerator or brake pedal to activate the system. The vehicle will descend the hill at a low speed. While the system is operating, the slip indicator light on the instrument panel will flash and the stop lights and high mounted stoplight will be lit. If you push the "DAC" switch to turn the system off while it is in operation, the system will stop operating gradually. The downhill assist control system indicator light will flash to alert the driver. To continue driving at a low speed, push the "DAC" switch to turn the system on.
