mixture.

Starting a cold engine
WARNING
Always make sure all control cables work
smoothly before you begin riding in cold
weather. If the control cables are frozen or do
not work smoothly, you could be unable to
control the vehicle, which could lead to an ac-
cident or collision.1. Apply the brake.
2. Shift the drive select lever into the neutral po-
sition.NOTE:_

When the drive select lever is in the neutral
position, the neutral indicator light should
come on. If the neutral indicator 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 is applied. However, it is recommend-
ed to shift into neutral before starting the en-
gine.

4. With your foot off the accelerator pedal, start
the engine by turning the key to “START”.NOTE:_ If the engine fails to start, release the key, and then
try starting again. Wait a few seconds before the
next attempt. Each cranking should be as short as
possible to preserve battery energy. Do not crank
the engine more than 5 seconds on each attempt. _

Jump-starting
Jump-starting the vehicle should be avoided. The
battery should be removed and charged instead.
(See pages 8-107–8-111 for battery removal and
installation procedures.) However, if the vehicle
must be jump-started, proceed as follows.
1. Turn the key to “OFF”.
2. Open the hood. (See pages 8-17–8-19 for
hood opening and closing procedures.)
3. Remove the battery compartment cover.
4. Using a charged 12 V battery, connect the
positive lead of the jumper cable to the posi-
tive terminal of the battery in the vehicle and
the other end of the positive lead to the posi-
tive terminal of the charged battery.

5. Connect the negative lead of the jumper ca-
ble to the negative terminal of the charged
battery and the other end of the negative lead
to an unpainted metal surface of the vehicle.
WARNING
Do not connect the negative lead of the jumper
cable to the negative terminal of the battery in
the vehicle.

Be especially careful not to:
touch the positive lead of the jumper
cable to the negative lead.
reverse the polarity of the jumper ca-
bles when connecting to the batteries -
battery explosion and/or serious dam-
age to the electrical system may occur.
_6. Start the engine. (Refer to “Starting a cold en-
gine” on pages 6-3–6-7.)

7. After the engine starts, disconnect the nega-
tive lead of the jumper cable from the vehicle
and charged battery, and then disconnect the
positive lead of the jumper cable from the
charged battery and the battery in the vehi-
cle.
8. Install the battery compartment cover.
9. Close the hood.

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 en-
gine is warm, check if it responds to the throttle
normally with the starter (choke) turned off.
