10–20 hours:
Avoid prolonged operation above three-quar-
ter throttle.
After break-in:
The vehicle may now be operated normally.EBU33081Starting 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. Apply the brake pedal.
3. Shift the drive select lever into the neutralposition. 
When the drive select lever is in the
neutral position, the neutral indicator
light should come on. If the neutral indi-
cator light does not come on, ask a
Yamaha dealer to inspect the electric
circuit.
 The engine can be started in any gear if
the brake 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.

Shifting: neutral to reverse
WARNING
EWB03300Before you shift into reverse, make sure
there are no obstacles or people behind
you. When it is safe to proceed, go slowly.
Hitting an obstacle or person could result
in serious injury or death. 1. Stop the vehicle, take your foot off the ac- celerator pedal, and check behind you.
2. Apply the brake pedal.
3. Shift from neutral to reverse by moving the drive select lever along the shift gui-
de.
When in reverse, the reverse indicator
light should be on. If the light does not
come on, ask a Yamaha dealer to in-
spect the reverse indicator light electri-
cal circuit.
 Due to the synchronizing mechanism in
the engine, the light may not come on
until the vehicle starts moving. 4. Release the parking brake, if applied.
5. Check behind the vehicle for people or
obstacles, and then release the brake
pedal.
6. Press the accelerator pedal gradually and
continue to watch to the rear while back-
ing.

EBU32530Checking the brake pedalHave a Yamaha dealer check the brakes at
the intervals specified in the periodic mainte-
nance and lubrication chart. There should be
no free play in the brake pedal. The brakes
should operate smoothly and there should be
no brake drag. If the brakes feel soft or
spongy, this could indicate air in the brake
system. Have a Yamaha dealer check the
brake system if necessary.
EBU33710Parking brakePull the parking brake lever rearward com-
pletely. If the parking brake lever clicks eight
times or more, have a Yamaha dealer adjust
the parking brake because the braking force
of the parking brake is weak. In addition, have
a Yamaha dealer check and adjust the park-
ing brake at the intervals specified in the peri-
odic maintenance and lubrication chart.EBU32551Brake light switch adjustmentThe brake light switch, which is activated by
the brake pedal, is properly adjusted when
the brake light comes on just before braking
takes effect.

If necessary, adjust the brake light switch.1. Hold the brake light switch in place.
2. Turn the adjusting nut in direction (a) to
make the brake light come on earlier.
3. Turn the adjusting nut in direction (b) to
make the brake light come on later.
EBU35930Cable inspection and lubrication
WARNING
EWB03380Damaged cables could restrict operation,
which may cause an accident or injury. In-
spect control cables frequently and re-
place damaged cables. Corrosion can
result when the outer covering of control
cables becomes damaged. Cables can
also become frayed or kinked. Lubricate the cable ends. If the cables do not
operate smoothly, ask a Yamaha dealer to re-
place them.EBU32570Brake pedal and accelerator pedal lu-
bricationLubricate the pivoting parts.

EBU33590Tail/brake light bulb replacementIf a tail/brake light bulb burns out, replace it as
follows:1. Remove the tail/brake light bulb holder
(together with the bulb) by turning it
counterclockwise.
2. Push the burnt-out bulb in and turn it counterclockwise to remove it from the
bulb holder.
3. Push a new bulb in and turn it clockwise to install in the bulb holder. 4. Install the bulb holder (together with the
bulb) by turning it clockwise.
EBU32700TroubleshootingAlthough Yamaha vehicles receive an inspec-
tion before shipment from the factory, trouble
may occur during operation. Any problem in
the fuel, compression, or ignition systems can
cause poor starting and loss of power. The
troubleshooting chart describes a quick, easy
procedure for making checks. If your vehicle
requires any repair, take it to a Yamaha deal-
er.
The skilled technicians at a Yamaha dealer-
ship have the tools, experience, and know-
how to properly service your vehicle. Use only
genuine Yamaha parts on your vehicle. Imita-
tion parts may look like Yamaha parts, but
they are often inferior. Consequently, they
have a shorter service life and can lead to ex-
pensive repair bills.
