EBU34910Parking brake indicator light “(P)”
This indicator light comes on when the park-
ing brake is applied.EBU36450High beam indicator light “ ”
This indicator light comes on when the high
beam of the headlight is switched on.EBU35851Differential gear lock indicator light “DIFF
LOCK”
This indicator light comes on when the front
differential gear is locked.TIPWhen the On–Command drive knob is set to
“DIFF LOCK”, the indicator light will flash until
the differential is locked. Turn the steering
wheel back and forth or drive slowly to help
the differential gear lock to engage.
EBU34921Drivetrain icon “ / ”
The drivetrain icon indicates what type of
drive mode is currently selected. When 2WD
is selected, the icon will turn off. When 4WD
is selected, “ ” is displayed. And when 4WD
with differential lock is selected “ ” is dis-
played.TIP See pages 5-21 and 7-10 for more informa-
tion on selecting the drive mode.
 Due to the synchronizing mechanism in the
differential gear case, the drivetrain icon
may not come on until the vehicle starts
moving.
 When the On-Command drive knob is set
to “DIFF LOCK” or “4WD”, the drivetrain
icon and the differential gear lock indicator
light will flash until the differential gear is
completely locked or unlocked. If the icon
and the indicator light continue to flash, the
differential is not completely locked or un-
locked. In this case, start moving slowly

and/or turn the steering wheel back and
forth to help the differential to lock or un-
lock. EBU34932Shift light
This light can be set to come on and go off at
the desired engine speeds and is used to in-
form the driver when it is time to upshift.
The electrical circuit of the shift light can be
checked by turning the key to “ ” (on). If the
light does not come on initially when the key
is turned to “ ” (on), or if the light remains
on, have a Yamaha dealer check the electrical
circuit.TIPSee page 5-16 for an explanation of how to
set the shift light.
EBU35283Coolant temperature warning light “ ”
This warning light comes on when the coolant
temperature, and therefore the engine, is out-
side its normal operating temperature range.
The warning light comes on in blue to inform
the driver that the vehicle should be warmed
up. After the engine is started, warm it up until
the warning light goes off.
The vehicle can be operated normally when
the warning light is off.
The warning light comes on in red when the
engine is overheating. If the red light comes
on, stop the vehicle as soon as it is safe to do
so and allow the engine to idle for about 10
minutes. If the warning light does not go off,
stop the engine and allow it to cool. (See page
9-71.)TIPIf you continue to drive the vehicle while the
engine is overheating, a buzzer will sound.

EBU31402On–Command drive knob
“2WD/4WD/DIFF LOCK”Stop the vehicle and move the On–Command
drive knob to change the drive mode to two–
wheel drive, four–wheel drive, or four–wheel
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.
EBU31413Accelerator pedalPress the accelerator pedal to increase en-
gine speed and thus vehicle speed. Release
the accelator pedal and spring tension will re-
turn the pedal to idle position.

NOTICEECB03020Do not use oils with a diesel specifica-
tion of “CD” or oils of a higher quality
than specified. In addition, do not use
oils labeled “ENERGY CONSERVING II”
or higher.
 Make sure that no foreign material en-
ters the oil tank. EBU35322TransmissionMake sure there is no oil leaking from the
transmission case.EBU31761CoolantCheck the coolant level in the reservoir and
replenish if necessary. (See page 9-36.)
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 11-1.

the engine is not warmed up or is overheat-
ing.
 the driver seat belt is not latched.
 the differential gear is locked (“DIFF LOCK”
is selected) or the differential gear lock indi-
cator is flashing.
 the parking brake is applied.
 an engine or system malfunction is detect-
ed (a warning light is on). To activate the launch system1. Confirm that the front wheels and steer-
ing wheel are pointed straight ahead.
2. Shift the transmission into first gear.
3. While pressing the brake pedal, pull both
shift paddles toward you and hold them
in that position. The launch system indi-
cator light will come on, and the launch
system enters standby mode. 4. While checking in front of you for obsta-
cles or anything that may cross your
path, release the brake pedal, and then
press the accelerator pedal to rev the en-
gine to the desired launch engine speed.
TIPThe engine speed at launch must be be-
tween 5000–10000 r/min.
 If you release one shift paddle, or if a sys-
tem restriction is detected during standby
mode, the launch system indicator light will
begin to flash and the launch will be can-
celled.

EBU35061Selecting the drive modeThe 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 th e On-Command drive knob. The drive mode icon
changes according to the selected drive mode. The drive mode icon and the “DIFF LOCK” indi-
cator light come on as follows:
Knob position Indication Drive mode
(none)
“2WD” (two-wheel drive): Drive power is supplied to the rear
wheels only.
“4WD” (four-wheel drive): Drive power is supplied to the
front and rear wheels.
“DIFF LOCK” (four-wheel drive with the differential gear
locked): Drive power is supplied to the front and rear 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 drive mode icon and the indicator light
will flash until the differential gear is completely locked or unlocked.
 Turning the steering wheel back and forth will help the differential gear lock to engage or dis-
engage.
 To protect the drivetrain from damage, vehicle speed is limited until the differential gear lock
has properly transitioned. UBAS7AE0.book Page 11 Wednesday, June 19, 2019 11:51 AM
