On-Command differential gear lock switch
“4WD”/”LOCK”
To lock the differential gear in 4WD, stop the vehi-
cle, make sure the On-Command four-wheel-drive
switch is set to “4WD”, move the select lever to po-
sition b, and then set the switch to “LOCK”. When
the differential gear is locked, the differential gear
lock indicator light (“DIFF.LOCK”) will come on
along with the differential gear lock indicator “”
in the multi-function meter unit display. To release
the differential gear lock, stop the vehicle and set
the switch to “4WD”.
WARNING
Always ride at a slow speed when the vehicle
is in 4WD-LOCK, and allow extra time and dis-
tance for maneuvers.
All wheels turn at the same speed when the dif-
ferential is locked, so it takes more effort to
turn the vehicle. The amount of effort is more
the faster you go. You may lose control and
have an accident if you cannot make a sharp
enough turn for the speed you are traveling.

NOTE:_

When the switch is set to “LOCK”, the differ-
ential gear lock indicator and indicator light
will flash until the differential gear is locked.


When the indicator and indicator light are
flashing, turning the steering wheel back and
forth will help the differential gear lock to en-
gage.


Riding before the differential gear lock is
properly engaged (e.g., when the indicator
and indicator light are flashing) will cause the
engine speed to be limited until engagement
is complete.

Make sure the final gear oil is at the specified level.
Add oil as necessary. (See pages 8-35–8-39 for
details.)
If desired, an SAE 80W90 hypoid gear oil may be
used for all conditions.NOTE:_ GL-4 is a quality and additive rating, GL-5 or GL-6
rated hypoid gear oils may also be used. _

fied level. Add oil as necessary. (See pages 8-41–

LEARNING TO OPERATE YOUR VEHICLE
You should become familiar with the performance
characteristics of the vehicle in a large, flat area
that is free of obstacles and other vehicles. Prac-
tice control of the accelerator pedal, brakes, steer-
ing, and drive select lever. Drive first at slow speed
and become comfortable at that speed before
gradually increasing your speed. Become familiar
with the way the vehicle feels in low and high rang-
es, first in two-wheel drive (2WD) and then in four-
wheel drive (4WD) and four-wheel drive with the
differential locked (DIFF. LOCK). Also practice
driving in reverse. Take the time to learn basic op-
eration before attempting more difficult maneu-
vers.

CAUTION:_ Do not shift from low to high or vice versa with-
out coming to a complete stop and waiting for
the engine to return to normal idle speed. Dam-
age to the engine or drive train may occur. _TURNING YOUR VEHICLE
The vehicle is easier to steer in two-wheel drive
(2WD) than four-wheel drive (4WD). Steering
takes the most effort in 4WD with the differential
locked (DIFF. LOCK).
It is possible for the vehicle to roll over or go out of
control if you attempt sharp, high-speed turns. You
should also be careful making sharp turns on
rough terrain. Do not attempt to turn around or
make abrupt maneuvers on slopes.

Differential gear oil
Checking the differential gear oil level
1. Place the vehicle on a level surface.
2. Remove the differential gear oil filler bolt and
check the oil level. It should be up to the brim
of the filler hole. If the level is low, add suffi-
cient oil of the recommended type to raise it
to the specified level.CAUTION:_ Be sure no foreign material enters the differen-
tial gear case. _3. Install the differential gear oil filler bolt, and
then tighten it to the specified torque.
Tightening torque:
Differential gear oil filler bolt:
23 Nm (2.3 m·kgf, 17 ft·lbf)
