Before you shift into reverse, make sure there
are no obstacles or people behind you. When it
is safe to proceed, go slowly. Hitting an obsta-
cle or person could result in serious injury or
death.1. Stop the vehicle. Take your foot off the accel-
erator pedal and check behind you.

Troubleshooting
Although Yamaha vehicles receive an inspection
before shipment from the factory, trouble may oc-
cur during operation. Any problem in the fuel, com-
pression, 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
When checking the fuel system, do not smoke
and make sure there are no open flames or
sparks in the area, including pilot lights from
water heaters or furnaces. Gasoline or gaso-
line vapors can ignite or explode, causing se-
vere injury or property damage.
