Multi-function display
WARNING
EWA12313
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 speedometer (which shows the
riding speed)
a digital tachometer (which shows
engine r/min)
an odometer (which shows the to-
tal distance traveled)
two tripmeters (which show the
distance traveled since they were
last set to zero)
a fuel reserve tripmeter (which
shows the distance traveled since
the bottom segment of the fuel
meter started flashing)
a clock
a fuel meter
a self-diagnosis deviceTIPBe sure to turn the key to “ON” be-
fore using the “SELECT” and “RE-
SET” buttons.
For the U.K. only: To switch the
speedometer and odometer/trip-
meter displays between kilome-
ters and miles, push the
“SELECT” and “RESET” buttons
together, then while holding thebuttons, turn the key to “ON”.
When the digits start flashing,
push the “SELECT” button to
change between kilometers and
miles.
Tachometer
The tachometer allows the rider to
monitor the engine speed and keep it
within the ideal power range.
When the key is turned to “ON”, the ta-
chometer needle sweeps once across
the r/min range and then returns to
zero r/min in order to test the electrical
circuit.

Pushing the “SELECT” button switch-
es the display between the tripmeter
modes “TRIP 1” and “TRIP 2” in the
following order:
TRIP 1 → TRIP 2 → TRIP 1When the fuel amount in the fuel tank
decreases to XT660Z 6.7 L (1.77 US
gal, 1.47 Imp.gal) - XT660ZA 5.8 L
(1.53 US gal, 1.28 Imp.gal), the bottom
segment of the fuel meter starts flash-
ing, and the tripmeter display automat-
ically changes to the fuel reserve
tripmeter mode “F-TRIP” and starts
counting the distance traveled from
that point. In that case, pushing the
“SELECT” button switches the display
between the various tripmeter modes
in the following order:
F-TRIP → TRIP 1 → TRIP 2 → F-TRIP
To reset a tripmeter, select it by push-
ing the “SELECT” button, and then
push the “RESET” button for at least
four seconds. If you do not reset the
fuel reserve tripmeter manually, it re-
sets itself automatically and the display
returns to the prior mode after refueling
