Failure to observe the following precautions may result in an accident.
● Do not use the rear differential lock system except when wheel spinning
occurs in a ditch or on a slippery or rugged surface. Large steering effort
and careful cornering control will be required.

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

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 “TRC turned off” is
shown on the multi-information display. Refrain from using the system until
the downhill assist control system indicator stays on and “TRC turned off” dis-
played on the multi-information display goes out. (The vehicle can be driven
normally during this time.)

● A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indicate
that a malfunction has occurred in downhill assist control system.
