Speedometer unit The speedometer unit is equipped with
the following:l
a digital speedometer (which
shows riding speed)
l
an odometer (which shows the to-
tal distance traveled)
l
two tripmeters (which show the
distance traveled since they were
last set to zero)
l
a fuel reserve tripmeter (which
shows the distance traveled on the
fuel reserve)
l
a clock
NOTE:@ For the U.K. only:
To switch the speedometer display be-
tween kilometers and miles, press the
“SELECT” button and “RESET” button
together for at least two seconds. @Odometer and tripmeter modes
Pushing the “SELECT” button switches
the display between the odometer
mode “ODO” and the tripmeter modes
“TRIP 1” and “TRIP 2” in the following
order:
ODO
® TRIP 1
® TRIP 2
® ODO
If the fuel level warning light comes on
(see page 3-2), the odometer display
will automatically change to the fuel re-
serve tripmeter mode “TRIP F” and
start counting the distance traveled
from that point. In that case, pushingthe “SELECT” button switches the dis-
play between the various tripmeter and
odometer modes in the following order:
TRIP F
® TRIP 1
® TRIP 2
® ODO
®
TRIP F
To reset a tripmeter, select it by push-
ing the “SELECT” button, and then
push the “RESET” button for at least
one second. If you do not reset the fuel
reserve tripmeter manually, it will reset
itself automatically and the display will
return to the prior mode after refueling
and traveling 5 km.
Clock mode
To change the display to the clock
mode, push the “SELECT” button for at
least one second.
To change the display back to the prior
mode, push the “SELECT” button.

faulty electrical circuit.
CB-26EIf the tachometer displays such an er-
ror code, note the circuit-specific num-
ber of r/min, and then have a Yamaha
dealer check the motorcycle.
EC000004
CAUTION:@ When the tachometer displays an
error code, the motorcycle should
be checked as soon as possible in
order to avoid engine damage. @
This model is also equipped with a self-
diagnosis device for the fuel level warn-
ing light circuit. If the fuel level warning
light circuit is defective, the following
cycle will be repeated until the malfunc-
tion is corrected: The warning light will
flash eight times, then go off for three
seconds. If this occurs, have a Yamaha
dealer check the motorcycle.
