Clutch fluid
Depress and release the clutch pedal five
times. Check to see if any fluid is leaking out
of the hoses, reservoir, or master cylinder.
Check the clutch fluid level and correct if nec-
essary. (See page 9-47.)TIPIf any leakage is found, or if the clutch pedal
offers little resistance, have a Yamaha dealer
service the vehicle. EBU36972FuelMake sure there is sufficient fuel in the tank.
Refuel if necessary.
WARNING
EWB02522Gasoline and gasoline vapors are ex-
tremely flammable. To avoid fires and ex-
plosions and to reduce the risk of injury
when refueling, follow these instructions.
1. Before refueling, turn off the engine andbe sure that no one is sitting in the vehi-
cle.
Never refuel while smoking, or while in
the vicinity of sparks, open flames, or
other sources of ignition such as the pilot
lights of water heaters and clothes dry-
ers.
2. Do not overfill the fuel tank. Because fuel expands when it heats up, heat from the
engine or the sun can cause fuel to spill
out of the fuel tank.
3. Wipe up any spilled fuel immediately.
4. Be sure the fuel tank cap is closed se- curely.
WARNING
EWB02532Gasoline is poisonous and can cause inju-
ry or death. Handle gasoline with care.
Never siphon gasoline by mouth. If you
should swallow some gasoline or inhale a
lot of gasoline vapor, or get some gasoline
in your eyes, see your doctor immediately.

Always place a portable fuel container on the
ground before filling it. Before removing the
container cap, touch the container with the
fuel dispenser nozzle. Keep fuel dispenser
nozzle in contact with container inlet when fill-
ing. WARNING! Never refill a fuel container
in the bed of any vehicle. Fire may result
from a build-up of static electricity. The
discharge of this build-up while refueling
can cause a spark and ignite the gasoline.[EWB03270]
EBU35680Engine oilMake sure the engine oil is at the specified
level. Add oil as necessary. (See page 9-16.)NOTICEECB03020 Do not use oils with a diesel specifica-
tion of “CD” or oils of a higher quality

A tire pressure gauge is included as standard
equipment. Make two measurements of the
tire pressure and use the second reading.
Dust or dirt in the gauge could cause the first
reading to be incorrect.
Tire pressure must be checked and set when
the tires are cold. The tire pressure should be
the same on both sides, and must be adjust-
ed according to vehicle loading conditions.
Set the tire pressure as specified below.
WARNING! Operation of this vehicle with
improper tire pressure may cause severe
injury or death from loss of control or roll-
over. Tire pressure below the minimum
specified could also cause the tire to dis-
lodge from the rim under severe driving
conditions.

OPERATION
EBU31880Read the Owner’s Manual carefully to be-
come familiar with all controls. If there is a
control or function you do not understand,
ask your Yamaha dealer.
WARNING
EWB03290Failure to familiarize yourself with the con-
trols can lead to loss of control, which
could cause an accident or injury. EBU35720Engine break-inThere is never a more important period in the
life of your vehicle than the period between 0
and 20 hours.
For this reason, we ask that you read the fol-
lowing material carefully. Because the engine
is brand new, you must not put an excessive
load on it for the first several hours of opera-
tion. During the first 20 hours, the variousparts in the engine wear and polish them-
selves to achieve the correct operating clear-
ances.
During this period, prolonged full-throttle op-
eration or any condition that might result in
excessive engine heating must be avoided.
However, momentary (2–3 seconds maxi-
mum) full-throttle operation under load does
not harm the engine.
Each full-throttle acceleration sequence
should be followed with a substantial rest pe-
riod for the engine, by cruising at lower r/min
so the engine can rid itself of the temporary
build-up of heat. If any abnormality is noticed
during this period, consult a Yamaha dealer.
0–10 hours:
Avoid prolonged operation above 5300 r/min.
Allow a cooling-off period of 5 to 10 minutes
after every hour of operation. Vary the speed
of the vehicle from time to time. Do not oper-
ate it at one set throttle position.UB5J7CE0.book Page 1 Thursday, November 26, 2020 1:37 PM

10–20 hours:
Avoid prolonged operation above 6300 r/min.
After break-in:
The vehicle may now be operated normally.EBU35342Starting the engine1. Turn the key to “ ” (on).NOTICEECB02291The coolant temperature warning light and
engine trouble warning light should come
on, then go off.
The EPS warning light should come on,
then go off when the engine is started.
To avoid possible damage, do not operate
the vehicle if a warning light does not work
as described above. 2. Press the brake pedal.
3. Shift the transmission into neutral.
When the transmission is in the neutral
position, the transmission gear display
shows “N” and the neutral indicator
light should come on.
 The engine can be started in any gear if
the clutch pedal is applied. However, it
is recommended to shift into neutral
before starting the engine.
4. With your foot off the accelerator pedal, start the engine by turning the key to “ ”
(start).
If the engine fails to start, release the key, and
then try starting it again. Wait a few seconds
before the next attempt. Each attempt should
be as short as possible, to preserve battery
energy. NOTICE: Do not crank the engine
more than 5 seconds on each attempt, or
starter damage could occur. Wait at least
5 seconds between each operation of the
electric starter to let it cool.
[ECB02140]
Do not turn the key to the “ ” (start) position
with the engine running; otherwise, damage
to the electric starter may result.

can cause the tires to lose traction, reducing
control and increasing the possibility of an ac-
cident.
WARNING
EWB00712Make sure the engine has sufficiently
slowed before shifting to a lower gear. En-
gaging a lower gear when the engine
speed is too high could make the wheels
stop rotating and lose traction. This could
cause loss of control, an accident and inju-
ry. It could also cause engine or drivetrain
damage. Recommended shift points
The recommended shift points during accel-
eration and deceleration are shown in the ta-
ble below.To drive in reverse
WARNING
EWB03300Before you shift into reverse, make sure
