low, “LO” will be displayed. When the coolant
temperature rises, the coolant temperature
display will begin to flash. If the coolant tem-
perature continues to rise, the message “HI”
will flash.TIPThe coolant temperature display can be set
to “°C” or “°F”. To switch the temperature
units, turn the key to “ ” (off), then hold
the “RESET” button pushed and turn the
key to “ ” (on).
The radiator fans turn on and off automati-
cally according to the coolant temperature.
Fuel gauge
The fuel gauge indicates the amount of fuel in
the fuel tank. The display segments of the fuel
gauge disappear from “F” (full) towards “E”
(empty) as the fuel level decreases. When the
last segment of the fuel gauge starts flashing,
refuel as soon as possible.1. Fuel gauge

NOTICEECB03020Do 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:

4. Install the differential gear oil drain boltand 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.
7. Install the differential gear 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.
EBU35112CoolantThe coolant level should be checked regular-
ly. In addition, the coolant must be changed
at the intervals specified in the periodic main-
tenance chart.TIPIf genuine Yamaha coolant is not available,
use an ethylene glycol antifreeze containing
corrosion inhibitors for aluminum engines and
mix with distilled water at a 1:1 ratio.
Tightening torque:Differential gear oil drain bolt:9.8 N·m (0.98 kgf·m, 7.2 lb·ft)
Tightening torque: Differential gear oil filler bolt:23 N·m (2.3 kgf·m, 17 lb·ft)
Recommended coolant:YAMALUBE coolant
Coolant quantity: Coolant reservoir (up to full level):0.56 L (0.59 US qt, 0.49 Imp.qt)
Radiator (including all routes): 3.78 L (4.00 US qt, 3.33 Imp.qt)

NOTICEECB02190Mix antifreeze with distilled water only.
However, if distilled water is not available,
soft water may be used for refilling. Do not
use hard water or salt water since they are
harmful to the engine. To check the coolant level1. Park the vehicle on a level surface.
2. Wait for the engine to cool for an accurate reading.
3. Look at the coolant level in the coolant reservoir. 4. If the coolant is at or below the minimum
level mark, remove panel C. (See page
9-11.)
5. Remove the coolant reservoir cap, add coolant up to the maximum level mark,
and then install the cap. NOTICE: If cool-
ant is not available, use distilled water
or soft tap water instead. Do not use
hard water or salt water since they are
harmful to the engine. If water has
been used instead of coolant, replace
1. Maximum level mark
2. Minimum level mark

Engine overheating
Wait for the engine to cool before removing the radiator cap. WARNING! If the engine is not
cool when removing the radiator cap, hot fluid and steam could blow out under pressure
and burn you.
[EWB03460]
Place a thick rag over the cap and remove the cap slowly to allow any re-
maining pressure to escape.
TIP Tap water can be used in an emergency. Ch ange to the recommended coolant as soon as
possible.
The engine will tend to overheat if the radiator is caked with mud, or if air was not properly bled
from the cooling system. Wait until the
engine has cooled.
Check the coolant le vel in the
coolant reservoir and/or radiator.
Level is OK.Level is low, check the
cooling system for leakage.
No
leakage.Leakage.
Ask a Yamaha dealer to inspect
and repair the cooling system.Add coolant. (See TIP.)
Restart the engine. If the engine o verheats again, ask a
Yamaha dealer to inspect and/or repair the cooling system.
