Parking on a slope
The parking brake is located on the rear drive
shaft. When the drivetrain is in “2WD” mode,
only the rear wheels will be locked. Therefore,
switch the drive mode to “DIFF LOCK” before
stopping the engine to lock all four wheels
when parking. In addition to the parking
brake, leave the transmission in gear to help
prevent the vehicle from rolling.
If you park on a hill that is too steep, the vehi-
cle may roll out of control. Never park on hills
that are so steep you cannot walk up them
easily. If you must park on an incline, follow
these instructions:1. First, bring the vehicle to a stop and con- tinue to apply the brake pedal.
2. Switch the drive mode to “DIFF LOCK”
and shift into first gear when parking up-
hill, or reverse gear when parking down-
hill.
TIPYou may need to turn the steering wheel left
and right or release the clutch slightly to help
the differential lock into place. 3. Stop the engine (turn the key to “ ”[off]).
4. With the brake pedal still being applied, set the parking brake.
5. Finally, get out of the vehicle and block
the front and rear wheels with rocks or
other objects.
Loading
Be aware that vehicle load includes the total
combined weight of the operator, passenger,
any installed accessories, and any luggage or
cargo brought on board or stored in the cargo
bed. Make sure that the gross vehicle weight
(vehicle load plus weight of the vehicle itself)
never exceeds 1065 kg (2348 lb).

4. Install the drain bolt and its new gasket,and then tighten the bolt to the specified
torque.
5. Refill with the recommended final gear oil up to the brim of the filler hole.
6. Check the oil filler bolt gasket for dam- age, and replace it if necessary. 7. Install the oil filler bolt and its gasket, and
then tighten the bolt to the specified
torque.
8. Check for oil leakage. If oil leakage is found, check for the cause.

gear oil at the intervals specified in the period-
ic maintenance chart.NOTICEECB03600When checking or changing the differen-
tial gear oil, make sure that no foreign ma-
terial enters the differential gear case. If
necessary, clean the differential gear oil
filler bolt and surrounding area.

TIPIf the recommended gear oil is not available,
SAE 80W-90 API GL-4 or GL-5 hypoid gear
oil may be used instead. Checking the differential gear oil level1. Park the vehicle on a level surface.
2. Remove the differential gear oil filler bolt and its gasket, and then check the oil lev-
el. It should be up to the brim of the filler
hole. 3. If the level is low, add sufficient oil of the
recommended type to raise it to the
specified level.
4. Check the gasket for damage, and re- place it if necessary.
5. Install the differential gear oil filler bolt
and its gasket, and then tighten the bolt
to the specified torque.

Changing the differential gear oil1. Park the vehicle on a level surface.
2. Place an oil pan under the differential
gear case to collect the used oil.
3. Remove the differential gear oil filler bolt,
the differential gear oil drain bolt and their
gasket to drain the oil. 4. Install the differential gear oil drain bolt
and its new gasket, and then tighten the
bolt to the specified torque.
5. Refill the differential gear case with the recommended oil.
6. Check the oil filler bolt gasket for dam- age, and replace it if necessary.
