drive with differential lock. Select the appro-
priate drive according to the terrain and driv-
ing conditions.
“2WD” (two–wheel drive): Power is sup-
plied to the rear wheels only.
 “4WD” (four–wheel drive): Power is sup-
plied to the front and rear wheels.
 “DIFF LOCK” (four–wheel drive with the dif-
ferential gear locked): Power is supplied to
the front and rear wheels with the differen-
tial gear locked. Unlike standard four–wheel
drive, all wheels turn at the same speed re-
gardless of traction.EBU33192Horn switch “ ”Press the switch to sound the horn.

NOTICEECB00301In order to prevent cl utch slippage (since
the engine oil also lubricates the clutch),
do not mix any chemical additives. Do
not use oils with a diesel specification of
“CD” or oils of a higher quality than
specified. In addition, do not use oils la-
beled “ENERGY CONSERVING II” or
higher.
 Make sure that no foreign material en-
ters the crankcase. EBU31761CoolantCheck the coolant level in the reservoir and
replenish if necessary. (See page 8-25.)
EBU36020Final gearMake sure there is no oil leaking from the final
gear case.EBU36030Differential gearMake sure there is no oil leaking from the dif-
ferential gear case.EBU31791Accelerator pedalBefore starting the engine, confirm that the
accelerator pedal operates correctly. It
should depress smoothly and spring back to
the idle position when released. Also check
the accelerator pedal for excessive free play.
If the accelerator pedal is not in correct work-
ing order, have the vehicle inspected before
starting off.
Recommended engine oil type and quantity:
See page 10-1.

EBU31922On-Command drive knobThe vehicle handles differently in each of the drive modes (“2WD”, “4WD” and “DIFF LOCK”). For
example, the vehicle requires more effort to turn in “DIFF LOCK” than in “2WD”. Always stop the
vehicle before changing the position of the On -Command drive knob. The meter display changes
according to the selected drive mode. The different drive indicators, and the differential gear lock
indicator light “DIFF. LOCK” come on as follows:
Knob position Indication Drive mode
No indicator light.
“2WD” (two-wheel drive): Power is supplied to the rear
wheels.
“4WD” (four-wheel drive): Power is supplied to the rear and
front wheels.
“DIFF LOCK” (four-wheel drive with the differential gear
locked): Power is supplied to the rear and front wheels and
the differential gear is locked.
Unlike in four-wheel drive, all wheels turn at the same
speed.

TIPWhen the knob is set to “DIFF LOCK” or “4WD”, the differential gear lock indicator and indica-
tor light will flash until the differential gear is completely locked or unlocked.
 When the indicator and indicator light are flas hing, turning the steering wheel back and forth
will help the differential gear lock to engage or disengage.
 Driving with the differential gear not properly engaged or disengaged (e.g., when the indicator
and indicator light are flashing) will cause the vehicle speed to be limited until the differential
gear is completely engaged or disengaged. UB3D7AE0.book Page 6 Tuesday, November 7, 2017 9:38 AM
