Multi-function display The multi-function display is equipped
with the following:

a speedometer (which shows the
riding speed)


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 fuel level warning light came
on)


a clock


a self-diagnosis device
NOTE:

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 kilometers
and miles, press the “SELECT”button 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 3-3), the odometer display
will automatically change to the fuel re-
serve tripmeter mode “F-TRIP” and
start counting the distance traveled

F-TRIP
To reset a tripmeter, select it by push-
ing the “SELECT” button, and then
push the “RESET” button for at least
one second while the selected tripme-
ter is flashing. If you do not reset the

Self-diagnosis device
This model is equipped with a self-diag-
nosis device for various electrical cir-
cuits.
If any of those circuits are defective, the
engine trouble warning light will come
on, and then the multi-function display
will indicate a two-digit error code (e.g.,
11, 12, 13).
If the multi-function display indicates
such an error code, note the code num-
ber, and then have a Yamaha dealer
check the vehicle.
CAUTION:
ECA11590
If the display indicates an error
code, the vehicle should be checked
as soon as possible in order to avoidengine damage.
This model is also equipped with a self-
diagnosis device for the immobilizer
system.If any of the immobilizer system circuits
are defective, the immobilizer system
indicator light will flash, and then the
multi-function display will indicate a
two-digit error code (e.g., 51, 52, 53)
when the key is turned to “ON”.
NOTE:If the multi-function display indicates er-
ror code 52, this could be caused by
transponder interference. If this errorappears, try the following.
1. Use the code re-registering key to
start the engine.NOTE:Make sure there are no other immobi-
lizer keys close to the main switch, and
do not keep more than one immobilizer
key on the same key ring! Immobilizer
system keys may cause signal interfer-
ence, which may prevent the enginefrom starting.
2. If the engine starts, turn it off, and
try starting the engine with the
standard keys.
3. If one or both of the standard keys
do not start the engine, take the
vehicle, the code re-registering

Fuel Make sure that there is sufficient fuel in
the tank. Fill the fuel tank to the bottom
of the filler tube as shown.
WARNING
EWA10880


Do not overfill the fuel tank, oth-
erwise it may overflow when the
fuel warms up and expands.


Avoid spilling fuel on the hot en-gine.
CAUTION:
ECA10070
Immediately wipe off spilled fuel
with a clean, dry, soft cloth, since
fuel may deteriorate painted surfac-es or plastic parts.
EAU13390
CAUTION:
ECA11400
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,as well as to the exhaust system.
Your Yamaha engine has been de-
signed to use premium unleaded gaso-
line with a research octane number of
95 or higher. If knocking (or pinging) oc-curs, use a gasoline of a different
brand. Use of unleaded fuel will extend
spark plug life and reduce maintenance
costs.
