Be sure to stop the vehicle before
making any setting changes to the
multi-function display.
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 device
NOTE:
●Be sure to turn the key to "ON"
before using the "SELECT" and
"RESET" buttons.

Tachometer
1. Tachometer
2. Red zone
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
tachometer needle will sweep once
across the r/min range and then return
to zero r/min in order to test the elec-
trical circuit.
ECA10030CAUTION:
Do not operate the engine in the
tachometer red zone.
Red zone: 7,500 r/min and above.

Tripmeter and tachometer modes
1. “SELECT” button
2. “RESET” button
Pushing the "SELECT" button switch-
es the display between the tripmeter
modes "TRIP 1" and "TRIP 2" in the
following order:
TRIP 1
6TRIP 2 6TRIP 1
When the fuel amount in the fuel tank
decreases to 6.7 L (1.77 US gal) (1.47
Imp.gal), the bottom segment of the
fuel meter will start flashing, and the
tripmeter display will automatically
change to the fuel reserve tripmeter
mode “F-TRIP” and start counting the
distance traveled from that point. In
that case, pushing the "SELECT" but-

ton switches the display between the
various tripmeter modes in the follow-
ing order:
F-TRIP
6TRIP 1 6TRIP 2 6F-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 will
reset itself automatically and the dis-
play will return to the prior mode after
refueling and traveling 5 km (3 mi).
