Speedometer
The speedometer shows the vehicle’s traveling
speed. The speedometer can be set to “MPH” or
“km/h”. This also changes the odometer and trip-
meter units between miles and kilometers. To
change the display between “MPH” and “km/h”,
turn the key to “ ” (off), then while holding the
“SELECT” button pushed, turn the key to “ ”
(on). Odometer and tripmeters
The odometer shows the total distance traveled
by the vehicle.
The tripmeters show the distance traveled since
they were last reset. The tripmeters can be used to
record the distance traveled on a single trip, or to
estimate the distance that can be traveled with a
full tank of gas, etc. The service tripmeter shows
the distance traveled since it was reset at the last
maintenance.

Push the “SELECT” button to switch between the
odometer “ODO”, the tripmeters “TRIP A” and
“TRIP B”, and the service tripmeter “ ” in the
following order:
ODO
→ TRIP A → TRIP B → → ODO
To reset a tripmeter, set the display to the tripme-
ter you want to reset, then push the “RESET” but-
ton for 2 seconds.
TIP The odometer will lock at 199999.
The tripmeters will reset and continue counting
after 9999.9 is reached.
Clock, hour meter, voltage display and coolant
temperature display
The clock displays time in 12-hour format. The
hour meter shows the total time the engine has
been running. The voltage display shows the bat-
tery voltage. The coolant temperature display
shows the temperature of the coolant.
Push the “MODE” button to switch between the
clock “CLOCK”, the hour meter “HOUR”, the volt-
age display “VOLT”, and the coolant temperature
display “ ” in the following order:1. Clock/Hour meter/Voltage display/Coolant temperature

Coolant temperature display
When the coolant is in the normal operating tem-
perature range, the temperature is displayed.
When the coolant temperature rises, the coolant
temperature display will begin to flash. If the cool-
ant temperature continues to rise, the message
“Hi” will flash. TIP
The coolant temperature display can be set to
“°C” or “°F”. To switch the temperature units,
turn the key to “ ” (off), then while holding the
“RESET” button pushed, turn the key to “ ”
(on).
The radiator fan turns on and off automatically
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
starts flashing, approximately 4.0 L (1.06 US gal,
0.88 Imp.gal) of fuel remains. Refuel as soon as
possible.

PRE-OPERATION CHECKS
EBU19226Inspect your vehicle each time you use it to make sure the vehicle is in safe operating condition. Always
follow the inspection and maintenance procedures and schedules described in the Owner’s Manual.
WARNING
EWB00482Failure to inspect or maintain the vehicle properly increases the possibility of an accident or equip-
ment damage. Do not operate the vehicle if you find any problem. If a problem cannot be corrected
by the procedures provided in this manual, have the vehicle inspected by a Yamaha dealer. Before using this vehicle, check the following points:
ITEMROUTINE PAGE
Fuel • Check fuel level in fuel tank,
and add recommended fuel if neces-
sary.
• Check fuel line for leakage. Correct if necessary. 4-22, 5-3
Engine oil • Check oil level in engine, and add recommended oil to specified
level if necessary.
• Check ATV for oil leakage. Correct if necessary. 5-3, 8-19
Final gear oil • Check ATV for oil leakage. Correct if necessary. 5-3, 8-24
Differential gear oil • Check ATV for oil leakage. Correct if necessary. 5-3, 8-26
Coolant • Check coolant level in reservoir, and add recommended coolant to
specified level if necessary.
• Check cooling system for leakage. Correct if necessary. 5-3, 8-28

EBU38000FuelMake sure there is sufficient gasoline in the tank
before starting off. Refuel if necessary. (See page
4-22.)EBU19561Engine oilMake sure that the engine oil is at the specified
level. Add oil as necessary. (See page 8-19.)EBU19591Final gear oilMake sure that the final gear oil is at the specified
level. Add oil as necessary. (See page 8-24.)EBU19601Differential gear oilMake sure that the differential gear oil is at the
specified level. Add oil as necessary. (See page
8-26.)EBU19632CoolantMake sure that the coolant is at the specified level.
Add coolant as necessary. (See page 8-28.)
TIPThe coolant level must be checked on a cold en-
gine since the level varies with engine tempera-
ture. EBU28533Front and rear brakesBrake levers and brake pedal
Check that there is no free play in the front
brake lever. If there is free play, have a Yamaha
dealer check the brake system.
Check for correct free play in the rear brake le-
ver and brake pedal. If the free play is incorrect,
adjust it. (See page 8-44.)
Check operation of the levers and pedal. They
should move smoothly and there should be a
firm feeling when the brake is applied. If not,
have a Yamaha dealer check them.
Brake fluid level (front brake)
Check the brake fluid level. Add fluid if necessary.
(See page 8-43.)
