4The multi-function display is equipped
with the following:
clock
fuel meter
coolant temperature meter
tripmeter display
information display
TIP
For the UK: To switch the displays be-
tween kilometers and miles, turn the



onds.
Clock
The clock uses a 24-hour time system.
To set the clock
1. Turn the main switch to “OFF”.2. Push and hold the “TRIP” switch.
3. Turn the main switch to “ON”
while pushing the “TRIP” switch,
and then continue to push the
“TRIP” switch for eight seconds.
The hour digits will start flashing.
4. Use the “TRIP” switch to set the
hours.
5. Push the “TRIP” switch for three
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.

7 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 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.
