(b) Shifting procedure
To shift between unlock and lock modes in “H”, push the
center differential lock button.
To shift between unlock and lock modes in “L”, push the
center differential lock button.
To shift between “H” and “L”, stop the vehicle, put the
transmission into “N” and move the four-wheel drive control
lever.
CAUTION
Never move the four-wheel drive control lever if wheels
are slipping. Stop the slipping or spinning before

NOTICE
For normal driving on dry and hard surface roads,
unlock the center differential. To prevent damage to the
center differential lock system, do not push the center

when its wheels are spinning freely off the ground. If the
indicator light does not go off when unlocking the
center differential, drive straight ahead while
accelerating or decelerating, or drive in reverse.
