SAFETY INFORMATION
1-4
1 Gasoline and exhaust gas


GASOLINE IS HIGHLY FLAMMA-
BLE:
Always turn the engine off when
refueling.
Take care not to spill any gaso-
line on the engine or exhaust
system when refueling.
Never refuel while smoking or in
the vicinity of an open flame.


Never start the engine or let it run
for any length of time in a closed
area. The exhaust fumes are poi-
sonous and may cause loss of
consciousness and death within a
short time. Always operate your
motorcycle in an area that has ad-
equate ventilation.


Always turn the engine off before
leaving the motorcycle unattended
and remove the key from the main
switch. When parking the motor-
cycle, note the following:
The engine and exhaust system
may be hot, therefore, park the
motorcycle in a place where pe-
destrians or children are not like-
ly to touch these hot areas.Do not park the motorcycle on a
slope or soft ground, otherwise it
may fall over.
Do not park the motorcycle near
a flammable source, (e.g., a ker-
osene heater, or near an open
flame), otherwise it could catch
fire.


When transporting the motorcycle
in another vehicle, make sure that
it is kept upright. If the motorcycle
should lean over, gasoline may
leak out of the fuel tank.


If you should swallow any gaso-
line, inhale a lot of gasoline vapor,
or allow gasoline to get into your
eyes, see your doctor immediately.
If any gasoline spills on your skin
or clothing, immediately wash the
affected area with soap and water
and change your clothes.

EAU32976
Multi-function display
WARNING
EWA12311
Be sure to stop the vehicle before
making any setting changes to themulti-function display.
The multi-function display is equipped
with the following:

a speedometer (which shows the
riding speed)


two tachometers, one LCD and
one digital (which show 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


an air intake temperature display


a fuel meter


a coolant temperature meter


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, tripmeter and digital ta-
chometer modes
Pushing the “SELECT” button switches
the display between the odometer
mode “ODO” and the tripmeter modes
“TRIP 1” and “TRIP 2” (“TRIP F”) and
the tachometer “E” in the following or-
der:
ODO → TRIP 1 → TRIP 2 → (TRIP F)
→ E → ODO
When the fuel amount in the fuel tank
decreases to 3.6 L (0.95 US gal) (0.79
Imp.gal), the bottom segment of the
fuel meter will start flashing, and the
odometer display 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 “SELECT” button
switches the display between the vari-
ous tripmeter and odometer modes in
the following order:
TRIP F → E → ODO → TRIP 1 → TRIP
2 → 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

3 itself automatically and the display will
return to the prior mode after refueling
and traveling 5 km (3 mi).
Clock
To switch the air intake temperature
display to the clock, first set the display
to the odometer or tachometer mode,
and then push the “RESET” button for
at least two seconds.
NOTE:The clock is automatically displayedwhen the key is turned to “OFF”.
To set the clock:1. Push the “SELECT” button and
“RESET” button together for at
least two seconds.
2. When the hour digits start flashing,
push the “RESET” button to set the
hours.
3. Push the “SELECT” button, and
the minute digits will start flashing.
4. Push the “RESET” button to set
the minutes.
5. Push the “SELECT” button and
then release it to start the clock.Air intake temperature mode
The temperature displayed may vary
from the outside temperature depend-
ing on engine conditions. To switch the
clock to the air intake temperature
mode, first set the display to the odom-
eter or tachometer mode, and then
push the “RESET” button for at least
two seconds.
Fuel meter
The fuel meter indicates the amount of
fuel in the fuel tank. The display seg-
ments of the fuel meter disappear to-
wards “E” (Empty) as the fuel level
decreases. When only one segment is
left near “E”, refuel as soon as possible.
NOTE:This fuel meter is equipped with a self-
diagnosis system. If the electrical circuit
is defective, the display segments will
flash. If this occurs, have a Yamahadealer check the electrical circuit.
Coolant temperature meter
With the key in the “ON” position, the
coolant temperature meter indicates
the temperature of the coolant. Whenthe key is turned to “ON”, all of the dis-
play segments of the coolant tempera-
ture meter will appear one after the
other and then disappear in order to
test the electrical circuit. The coolant
temperature varies with changes in the
weather and engine load. If the top seg-
ment flashes, stop the vehicle and let
the engine cool. (See page 6-36.)
CAUTION:
ECA10020
Do not operate the engine if it isoverheated.
Self-diagnosis devices
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.,
12, 13, 14).
This model is also equipped with a self-
diagnosis device for the immobilizer
system.

EAU13320
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 regular unleaded gaso-
line with a research octane number of
91 or higher. If knocking (or pinging) oc-
curs, use a gasoline of a different brand
