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.

gine” on pages 6-3–6-7.)

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.

WARNING
Going down a hill improperly could cause loss
of control or cause the vehicle to overturn.

Always check the terrain carefully before
you start down any hill.


Never go down a hill at high speed.


Avoid going down a hill at an angle that
would cause the vehicle to lean sharply to
one side. Go straight down the hill where
possible.
Before starting down hill, make sure the vehicle is
in low-range 4WD. On most slopes, this will let you
use engine braking to help you go downhill slowly.
Go as slowly as possible. If you are starting to go
too fast, apply the brakes gently. Avoid sudden ap-
plication of the brakes, which could cause the ve-
hicle to start sliding.
If you are sliding or skidding, try to steer in the di-
rection the vehicle is sliding to help you regain con-
trol.

Troubleshooting
Although Yamaha vehicles receive a rigid 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 mak-
ing checks. If your vehicle requires any repair, take
it to a Yamaha dealer.
The skilled technicians at a Yamaha dealership
have the tools, experience, and know-how to prop-
erly service your vehicle. Use only genuine
Yamaha parts on your vehicle. Imitation parts may
look like Yamaha parts, but they are often inferior.
Consequently, they have a shorter service life and
can lead to expensive repair bills.
WARNING
Do not smoke when checking the fuel system.
Fuel can ignite or explode, causing severe in-
jury or property damage. Make sure there are
no open flames or sparks in the area, including
pilot lights from water heaters or furnaces.
