DESCRIPTION
When the ON/OFF switch of the multi-terrain select switch is turned on, multi-terrain select control is enabled and the multi-terrain select indicator light illuminates.
After selecting a road surface type using the mode selector switch of the multi-terrain select switch, the system optimizes throttle control and brake fluid pressure control for wheels that slip when accelerating, which allows the power lost when the wheels slip during acceleration to be distributed to all 4 wheels.
The slip indicator light blinks while the system is operating.
The system can operate under the following conditions:
When there is a malfunction in the multi-terrain select system, the multi-terrain select indicator light blinks.
