If you think or feel that the vehicle may tip or
roll, keep your body completely inside the
protective structure of the vehicle:
Brace yourself by pressing your feet firmly
on the floorboard and keep a firm grip on
the steering wheel or passenger handhold.
 Do not put your hands or feet outside of the
vehicle for any reason. Do not try to stop a
tipover using your arm or leg.
Accelerating
Avoid higher speeds and sudden or hard ac-
celeration until you are thoroughly familiar
with the operation of your vehicle. Avoid sud-
den or hard acceleration in any turn. Never
drive faster than is safe for current conditions.
Shifting
Follow the instructions on pages 6-2 and 6-3
for shifting, downshifting, and shifting into re-
verse until you are thoroughly familiar with
each operation. Braking
When slowing down or stopping, take your
foot off the accelerator pedal and press the
brake pedal smoothly. Abrupt or improper
use of the brakes can cause the tires to lose
traction, reducing control of the vehicle and
increasing the possibility of an accident.
Braking ability is affected by type of terrain. In
most cases, gradual application of the brakes
is more effective than abrupt braking, partic-
ularly on loose surfaces
, such as gravel. Al-
ways allow for greater braking distance on
rough, loose, or slippery surfaces.
Engine compression braking will also help
slow the vehicle down. With the transmission
still in gear, take your foot off the accelerator
and allow the drivetrain and engine to absorb
vehicle speed. Downshift as necessary. Ap-
plication of the brakes provides additional
stopping power.UB0F7AE0.book Page 15 Monday, November 6, 2017 2:30 PM

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
