Tachometer
The electric tachometer allows the rid-
er to monitor the engine speed and
keep it within the ideal power range.
When the vehicle power is turned on,
the tachometer needle will sweep once
across the r/min range and then return
to zero r/min in order to test the electri-
cal circuit.
NOTICE
ECA10032
Do not operate the engine in the ta-
chometer red zone.
Red zone: 10000 r/min and above

WARNING
EWA12423
Be sure to stop the vehicle before
making any setting changes to the
multi-function meter unit. Changing
settings while riding can distract the
operator and increase the risk of an
accident.
The “TRIP/INFO” switch is located on
the right side of the handlebar. This
switch allows you to control or change
the settings of the multi-function meter
unit. To use the “TRIP” switch, move
the “TRIP/INFO” switch in direction (a).
To use the “INFO” switch, move the
“TRIP/INFO” switch in direction (b).

US gal, 0.53 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 7-34.)
NOTICE
ECA10022
Do not continue to operate the en-
gine if it is overheating.
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.
Tripmeter display
The tripmeter display is equipped with
the following:
odometer
tripmeter
time tripmeter
fuel reserve tripmeter
oil change tripmeter
V-belt replacement tripmeter
Push the “TRIP” switch to change the
display between the odometer “Odo”,
tripmeter “Trip”, time tripmeter “Trip
Time”, oil change tripmeter “Oil Trip”,
and V-belt replacement tripmeter “V-
Belt Trip” in the following order:
Odo → Trip → Trip Time → Oil Trip →
V-Belt Trip → Odo
TIP
When approximately 2.4 L (0.63 US
gal, 0.53 Imp.gal) of fuel remains in the
fuel tank, the last segment of the fuel
meter will start flashing. The display
will automatically change to the fuel re-

counting the distance traveled from
that point.

TIP
If traveling at speeds under 10 km/h (6
mi/h), “_ _._” is displayed.
Average speed display
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.
Warning message 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.
“OIL SERV”: Appears when the oil
change indicator “OIL” starts flashing.
If “OIL SERV” is displayed, change the
engine oil, and then reset the oil
change indicator and oil change trip-
meter.
“V-BELT SERV”: Appears when the V-
belt replacement indicator “V-Belt”
starts flashing. If “V-BELT SERV” is
displayed, replace the V-belt, and then
reset the V-belt replacement indicator
and V-belt replacement tripmeter.
When there are two or more warnings,
the warning messages are displayed in
the following order:
L FUEL → H TEMP → ICE → OIL SERV
→ VBELT SERV → L FUEL

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 foreign 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.
EAU20071
Coolant
The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU78580To check the coolant level
1. Place the vehicle on the center-
stand.
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 through
the check window.
TIP
The coolant should be between the
minimum and maximum level marks.

73. If the coolant is at or below the
minimum level mark, remove the
left floorboard mat by pulling it up.
4. Remove the coolant reservoir cov-
er.
5. Remove the coolant reservoir cap,
add coolant to the maximum level
mark, and then install the reservoir
cap. WARNING! Remove only
the coolant reservoir cap. Never
attempt to remove the radiator
cap when the engine is hot.
[EWA15162] NOTICE: If coolant is not
available, use distilled water or
soft tap water instead. Do not
use hard water or salt water
since it is harmful to the engine.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the cooling system will notbe protected against frost and
corrosion. If water has been
added to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as
soon as possible, otherwise the
effectiveness of the coolant will
be reduced.
[ECA10473]
6. Install the coolant reservoir cover.
7. Place the left floorboard mat in the
original position and push it down-
ward to secure it.
EAU33032Changing the coolant
The coolant must be changed at the in-
tervals specified in the periodic mainte-
nance and lubrication chart. Have a
Yamaha dealer change the coolant.
WARNING! Never attempt to remove
the radiator cap when the engine is
hot.

7 Engine overheating
WARNING
EWAT1041
Do not remove the radiator cap when the engine and radiator are hot.
Scalding hot fluid and steam may be blown out under pressure, which
could cause serious injury. Be sure to wait until the engine has cooled.
Place a thick rag, like a towel, over the radiator cap, and then slowly ro-
tate the cap counterclockwise to the detent to allow any residual pres-
sure to escape. When the hissing sound has stopped, press down on the
cap while turning it counterclockwise, and then remove the cap.
TIP
If coolant is not available, tap water can be temporarily used instead, provided
that it is changed to the recommended coolant as soon as possible.
Wait until the engine
has cooled.
Check the coolant
level in the reservoir
and radiator.Add coolant.
(See TIP.)
The coolant level is
OK.
There is no leakage.
There is leakage.
The coolant level is
low.
Check the cooling
system for leakage.
Have a Yamaha
dealer check and
repair the cooling
system.
Start the engine. If the engine overheats again,
have a Yamaha dealer check and repair the cooling
system.
