CAUTION:l
Do not use accessories requiring more
than the above maximum capacity. This
may overload the circuit and cause the
fuse to blow.
l
If accessories are used without the engine
running or with the headlight turned on,
the battery will lose its charge and engine
starting may become difficult.
l
Do not use an automotive cigarette light-
er or other accessories with a plug that
gets hot because the jack can be dam-aged.

Starting a warm engine
To start a warm engine, refer to the “Starting a
cold engine” section. The starter (choke)
should not be used. The throttle should be
opened slightly.
EBU00182
Warming up
To get maximum engine life, always warm up
the engine before starting off. Never accelerate
hard with a cold engine! To see whether or not
the engine is warm, check if it responds to the
throttle normally with the starter (choke)
turned off.

The drive select lever cannot be shifted into or
from reverse or park without applying the rear
brake.

return the throttle lever to the closed posi-
tion.
b. Apply the rear brake pedal.
c. Shift from neutral to reverse or from re-
verse to park and vice versa by moving
the drive select lever along the shift guide.
NOTE:

l
When in reverse, the reverse indicator
light should be on. If the light does not
come on, ask a Yamaha dealer to inspect
the reverse indicator light electrical circuit.

1. Lean towards inside of turn.
2. Support your weight on the outer footboard.
1. Se pencher vers l’intérieur du virage.
2. S’appuyer sur le repose-pied extérieur.
1. Inclínese hacia el interior del giro.
2. Descanse su peso en el descansapie exterior.
As you approach a curve, slow down and be-
gin to turn the handlebars in the desired direc-
tion. As you do so, put your weight on the
footboard to the outside of the turn (opposite
your desired direction) and lean your upper
body into the turn. Use the throttle to maintain
an even speed through the turn. This maneu-
ver will let the wheel on the inside of the turn
slip slightly, allowing the ATV to make the turn
properly.
This procedure should be practiced at slow
speed many times in a large off-road area with
no obstacles. If an incorrect technique is used,
your ATV may continue to go straight. If the
ATV doesn’t turn, come to a stop and then
practice the procedure again. If the riding sur-
face is slippery or loose, it may help to position
more of your weight over the front wheels by
moving forward on the seat.
Once you have learned this technique you
should be able to perform it at higher speeds
or in tighter curves.
