Rear differential lock system To shift from "H4" to "H2", push the "4WD" button again to turn it off. This can be done at any vehicle speed. If the indicator light does not go off when you shift the transfer into "H2", drive straight ahead while accelerating or decelerating, or drive in reverse. SHIFTING BETWEEN "H2" OR "H4" AND "L4" To shift from "H2" or "H4" to "L4", stop the vehicle and put the transmission in "N".

With your foot holding down the brake pedal, move the front drive control lever. When the "4WD" button is pushed in, the transfer shifts into "H4"; when the button is left out, the transfer shifts into "H2". If the indicator light does not go off when you shift the transfer into "H2", drive straight ahead while accelerating or decelerating, or drive in reverse. The rear differential lock system is provided for use only when wheel spinning occurs in a ditch or on a slippery or ragged surface. This differential lock system is effective in case one of the rear wheels is spinning. Before using the rear differential lock system, first shift the front drive control into "L4" with the free-wheeling hubs engaged to see if it works. If this has no effect, additionally use the rear differential lock system. 86
