Conditions in which the downhill assist control system does not oper-
ate
●
In the following situations, the downhill assist control system indicator
flashes and the downhill assist control system does not operate or will
stop operating:
• The shift lever is not in “1” range of S mode or R.
• The vehicle speed is higher than 15 mph (25 km/h).
●
If the accelerator or brake pedal is depressed, the downhill assist control
system will stop operating with the downhill assist control system indica-
tor still on.
■
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
●
A sound may be heard from the engine compartment during operation of
the downhill assist control system. This sound does not indicate a mal-
function.
●
If the accelerator or brake pedal is depressed during operation of the
downhill assist control system, a sound caused by the release of system
operation may be heard, or you may feel the brake pedal push-back. This
does not indicate a malfunction.
■
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 con-
trol 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.
