■ Operating tips
First turn the four-wheel drive control
switch to “L4” with the center differential
locked to see if you can move forward. If
this does not work, use the rear differential
lock system also.
● Be sure to stop the wheels before locking
the differential.
● Unlock the differential as soon as the
vehicle moves out.
■ Unlocking the rear differential
If the rear differential lock indicator still
flashes even after unlocking the rear differ-
ential, check the safety of the surrounding
area and slightly turn the steering wheel in
either direction while the vehicle is in
motion.
■ Automatic unlocking feature
The rear differential will also unlock if you
turn the four-wheel drive control switch to
“H4” or unlock the center differential.
■ After unlocking the rear differential
Check that the indicators go off.
