by mode, have a Yamaha dealer check the vehicle.

the auto-off function may be acti-
vated. Turn the key to “OFF” and
then back to “ON”.
3. Are all switches working properly?
After checking the above, and a light
does still not come on, proceed with the
following.

If the headlight fails to come on,
the bulb may be burned out. Refer
to page 8-11 for replacement pro-
cedures.

If a tail/brake light or turn signal
light fails to come on, a bulb may
be burned out. Refer to page 8-12
or 8-13 for replacement proce-
dures.
If a light still does not come on, a fuse
