With the downhill assist control system, the vehicle is able to descend a steep hill, maintaining a constant low speed of about 3 mph (5 km/h) without brake pedal operation.
Activating the downhill assist control system
Activating the downhill assist control system press the “dac” switch.
The downhill assist control system indicator will come on to indicate that the downhill assist control system is activated.
Pressing the switch again turns the system off.
While the downhill assist control system is operating
The slip indicator will flash to indicate that the downhill assist control system is operating, and the stop lights and high mounted stoplight will turn on.
Conditions in which the downhill assist control system does not operate
If the “dac” switch is turned off during operation of the downhill assist control system
The downhill assist control system gradually ceases operation. The downhill assist control system indicator will flash during the canceling operation, and then go off when the system is fully off.
Downhill assist control system operation sound
When the downhill assist control system operates continuously
The brake actuator may overheat. In that case, the downhill assist control system will stop operating, a buzzer will sound and the downhill assist control system indicator will start flashing. Refrain from using the system until the downhill assist control system indicator stays on. (There is no problem with continuing to drive normally.)
If the slip indicator comes on
It may indicate a malfunction in the system. Contact your toyota dealer.
