seconds, and then release it. The
minute digits will start flashing.
6. Use the “TRIP” switch to set the minutes.
7. Push the “TRIP” switch for three seconds, and then release it to
start the clock.
Fuel meter
The fuel meter indicates the amount of
fuel in the fuel tank. The segments of
the fuel meter disappear from “F” (full)
towards “E” (empty) as the fuel level
decreases. When the last segment of
the fuel meter starts flashing, refuel as
soon as possible.
TIP If a problem is detected in the fuel
meter, the all segments will flash
repeatedly. If this occurs, have a
Yamaha dealer check the vehicle.
 When approximately 2.3 L (0.61
US gal, 0.51 Imp.gal) of fuel re-
mains in the fuel tank, the last seg-
ment of the fuel meter will start
flashing. The display will automat-
ically change to the fuel reserve
tripmeter “F Trip” and start count-
ing the distance traveled from that
point.Coolant temperature meter The coolant temperature meter indi-
cates the temperature of the coolant.
If the top segment flashes, stop the ve-
hicle, then stop the engine, and let the
engine cool. (See page 8-33.)
NOTICE
ECA10022
Do not continue to operate the en-
g
ine if it is overheatin g.TIP If a problem is detected in the
coolant temperature meter, all
segments will flash repeatedly. If
this occurs, have a Yamaha dealer
check the vehicle as soon as pos-
sible.
 The coolant temperature varies
with changes in the weather and
engine load.

5 Instantaneous fuel consumption
d
isplay
This function calculates the fuel con-
sumption under current riding condi-
tions.
The instantaneous fuel consumption
can be displayed as either
“Consumption_ _._km/L”,
“Consumption_ _._L/100 km” or
“Consumption_ _ _._MPG” (for the
UK).  “Consumption_ _._km/L”: The
distance that can be traveled on
1.0 L of fuel under the current rid-
ing conditions is shown. 
“Consumption_ _._L/100 km”:
The amount of fuel necessary to
travel 100 km under the current
riding conditions is shown.
 “Consumption_ _ _._MPG” (for the
UK): The distance that can be
traveled on 1.0 Imp.gal of fuel un-
der the current riding conditions is
shown.
TIPIf traveling at speeds under 10 km/h (6
mi/h), “_ _._” is displayed.Averag e speed d isplay
The average speed “Average_ _ _kmh”
or “Average_ _ _MPH” (for the UK) is
displayed. The average speed is the total distance
divided by the total time (with the main
switch in the “ON” position) since the
display was last reset to zero.
This display shows the average speed
since it was last reset.
To reset the average speed display,
select it by pushing the “INFO” switch,
and then push the “INFO” switch for
three seconds.
Warnin
g messa ge function
This function displays a warning mes-
sage corresponding to the current
warning.
“L FUEL”: Appears when the last seg-
ment of the fuel meter starts flashing. If
“L FUEL” is displayed, refuel as soon
as possible.
“H TEMP”: Appears when the top seg-
ment of the coolant temperature meter
starts flashing. If “H TEMP” is dis-
played, stop the vehicle, then stop the
engine, and let the engine cool.
“ICE”: Appears when the icy road
warning indicator “ ” starts flashing. If
“ICE” is displayed, be careful of icy
roads.

5. Remove the final transmission oil
drain bolt and its gasket to drain
the oil from the final transmission
case. 6. Install the final transmission oil
drain bolt and its new gasket, and
then tighten the bolt to the speci-
fied torque.
7. Refill with the specified amount of the recommended final transmis-
sion oil. WARNING! Make sure
that no forei gn material enters
the final transmission case.
Make sure that no oil gets on
the tire or wheel.
[EWA11312]
8. Install the final transmission oil fill- er cap and its new O-ring, and
then tighten the oil filler cap.
9. Check the final transmission case for oil leakage. If oil is leaking,
check for the cause.

CoolantThe coolant level should be checked
regularly. In addition, the coolant must
be changed at the intervals specified in
the periodic maintenance chart.TIPIf genuine Yamaha coolant is not avail-
able, use an ethylene glycol antifreeze
containing corrosion inhibitors for alu-
minum engines and mix with distilled
water at a 1:1 ratio.

TIP The coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
 Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.2. Check the coolant level in the
coolant reservoir.TIPThe coolant should be between the mi-
nimum and maximum level marks.
3. If the coolant is at or below the mi-nimum level mark, have a Yamaha
dealer add coolant to the reser-
voir.

Chan gin g the coolant
The coolant must be changed at the in-
tervals specified in the periodic main-
tenance and lubrication chart. Have a
Yamaha dealer change the coolant.
WARNING! Never attempt to remove the ra diator cap when the en gine is
hot.

Air filter an
d V- belt case air fil-
ter elementsThe air filter element should be re-
placed and the V-belt case air filter el-
ement should be cleaned at the
intervals specified in the periodic main-
tenance and lubrication chart. Service
the air filter elements more frequently if
you are riding in unusually wet or dusty
areas. The air filter check hose and V-
belt case air filter check hose must be
frequently checked and cleaned if nec-
essary.
