Fuel level warning light “ ”
This warning light comes on when the
fuel level drops below approximately
1.0 L (0.26 US gal, 0.22 Imp.gal). When
this occurs, refuel as soon as possible.
The electrical circuit of the warning light
can be checked by turning the key
to “ ”. The warning light should come
on for a few seconds, and then go off.
If the warning light does not come on

gine overheats. If this occurs, stop the
engine immediately and allow the en-
gine to cool.
The electrical circuit of the warning light
can be checked by turning the key
to “ ”. The warning light should come
on for a few seconds, and then go off.

For radiator-fan-equipped vehi-
cles, the radiator fan(s) automati-
cally switch on or off according to
the coolant temperature in the ra-
diator.

Speedometer unit (NS50N)The speedometer unit is equipped with
a speedometer, an odometer and a fuel
meter. The speedometer shows riding
speed. The odometer shows the total
distance traveled. The fuel meter indi-
cates the amount of fuel in the fuel tank.

Multi-function display (NS50)TIPThe multi-function display performs the
following self-test for three seconds in
order to check the electrical circuit.●
The speedometer digits display
from 0 to 80, and then from 80 to 0
in kilometers. If the speedometer is
set to miles, the digits will display
from 0 to 50, and then from 50 to 0.
●
All LCD segments and warning
lights come on and then go off.
WARNING
EWA12312
Be sure to stop the vehicle before
making any setting changes to the
multi-function display. Changing
settings while riding can distract the
operator and increase the risk of an
accident.The multi-function display is equipped
with the following:●
a digital clock
●
a digital speedometer (which
shows riding speed)
●
an odometer (which shows the to-
tal distance traveled)
●
a tripmeter (which shows the dis-
tance traveled since it was last set
to zero)
●
a fuel reserve tripmeter (which
shows the distance traveled on the
fuel reserve)
●
a fuel gauge
●
a self-diagnosis device
TIP●
Be sure to turn the key to “ ” be-
fore using the “RESET/SELECT”
button.
●
For the U.K. only: To switch the
speedometer and odometer/trip-
meter displays between kilometers
and miles, when the main switch is
turned to “ ”, press the “RE-
SET/SELECT” button for at least
eight seconds.
To set the clock:1. Select the odometer and push the
“RESET/SELECT” button for at
least three seconds.
2. When the hour digits start flashing,
push the “RESET/SELECT” button
to set the hours.
3. To change the minutes digits, push
the “RESET/SELECT” button for
at least three seconds.

TIPAfter setting the clock, be sure to push
the “RESET/SELECT” button for at
least three seconds before turning the
key to “ ”, otherwise the clock will not
be set.Odometer and tripmeter modes
Pushing the “RESET/SELECT” button
switches the display between the
odometer mode “ODO” and the tripme-
ter “TRIP” in the following order:ODO → TRIP → ODO
If the fuel level warning indicator comes
on (see page 3-2), the odometer dis-
play will automatically change to the
fuel reserve tripmeter mode “TRIP F”
and start counting the distance traveled
from that point. In that case, pushing
the “RESET/SELECT” button switches
the display between the various tripme-
ter and odometer modes in the follow-
ing order:
TRIP F → ODO → TRIP → TRIP FTo reset a tripmeter, select it by push-
ing the “RESET/SELECT” button, and
then push it again for at least three sec-
onds. If you do not reset the fuel re-
serve tripmeter manually, it will reset
itself automatically and the display will
return to the prior mode after refueling
and traveling 5 km (3 mi).
TIPThe display cannot be changed back to
“TRIP F” after pushing the “RESET/SE-
LECT” button.Fuel gauge
The fuel gauge indicates the amount of
fuel in the fuel tank. The display seg-
ments of the fuel gauge disappear to-
wards “E” (Empty) as the fuel level

TIP●
The annual checks must be performed every year, except if a kilometer-based maintenance, or for the UK, a
mileage-based maintenance, is performed instead.
●
From 30000 km (17500 mi), repeat the maintenance intervals starting from 6000 km (3500 mi).
●
Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and technical
skills.
