Conditions in which the downhill assist control system does not oper-
ate or will stop operating
●
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 L or R.
• The vehicle speed is higher than 15 mph (25 km/h).
●
If the accelerate or brake pedal is depressed, the downhill assist control
system will stop operating with the downhill assist control system indica-
tor stayed on.
■
If the “DAC” switch is turned off while the downhill assist control sys-
tem is operating
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 while the downhill
assist control system is operating. This sound does not indicate a mal-
function.
●
If the accelerator or brake pedal is depressed while the downhill assist
control system is operating, 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 driving normally.)
■
If the slip indicator comes on
It may indicate a malfunction in the system. Contact your Toyota dealer.
