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 con-
tinue driving at a low speed, push the
"DAC" switch to turn the system on.
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 inter-
mittently.
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 de-
creases, 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 follow-
ing systems under conditions such as on
slippery roads.

If the brake actuator temperature becomes
too high while any of the systems is oper-
ating, a buzzer will start to sound intermit-
tently 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
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 or-
der to protect the brake actuator. (Al-
though the downhill assist control system
does not operate, it is no problem to con-
tinue your driving.) The system will be
automatically restored after a short time
and the slip indicator light goes out.
