■Operating tips (vehicles with automatic transmission)
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
● The transfer mode is in H2.
● The rear differential is locked. (if equipped)
■ 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 or H4.
• The rear differential is locked. (if equipped)
• The shift lever is in P. (vehicles with automatic transmission)
• The accelerator or brake pedal is depressed.
• The vehicle speed exceeds approximately 30 km/h (18 mph).
• The brake system overheats.
● In the following situations, the indicator flashes to alert the driver, but the
