■ Operating tips
The system will operate when the shift lever is in a position other than P, how-
ever to make effective use of the system it is recommended to select a lower
shift range.
■ The system will not operate when
● Part-time 4WD models: The transfer mode is in H2 or H4.
● Full-time 4WD models: The transfer mode is in H4L or H4F.
■ If the downhill assist control system indicator flashes
● In the following situations, the indicator flashes and the system will not oper-
ate:
• The transfer mode is not in L4 (part-time 4WD models) or L4L (full-time
4WD models).
• The shift lever is in P.
• The accelerator or brake pedal is depressed.
• The vehicle speed exceeds approximately 15 mph (25 km/h).
• The brake system overheats.
● In the following situations, the indicator flashes to alert the driver, but the
system will operate:
• The shift lever is in N.
• The “DAC” switch is turned off while the system is operating.
The system will gradually ceases operation. The indicator will flash during
operation, and then go off when the system is fully off.
■ When the downhill assist control system is operated continuously
This may cause the brake actuator to overheat. In this case, the downhill
assist control system will stop operating, a buzzer will sound and the downhill
assist control system indicator will start flashing, and the “TRAC OFF” indica-
tor light will come on. Refrain from using the system until the downhill assist
control system indicator stays on and “TRAC OFF” indicator light turns off.
(The vehicle can be driven normally during this time.)
