INSTRUMENT AND CONTROL FUNCTIONS

EAUM1470
Fuel gauge The fuel gauge indicates the amount of
fuel in the fuel tank. The needle moves
towards “E” (Empty) as the fuel level
decreases. When the remaining fuel in
the tank reaches approximately 2.7 L
(0.72 US gal) (0.60 Imp.gal), the fuel
level warning light will come on and the
multi-function display will automatically
change to the “Trip/fuel” mode. (See
page 3-3.) If this occurs, refuel as soon
as possible.NOTE:Do not allow the fuel tank to empty itselfcompletely.
EAU12171
Coolant temperature gauge With the key in the “” position, the
coolant temperature gauge indicates
the temperature of the coolant. The
coolant temperature varies with chang-
es in the weather and engine load. If
the needle reaches or enters the red
zone, stop the vehicle and let the en-
gine cool. (See page 6-28.)CAUTION:
ECA10020
Do not operate the engine if it isoverheated.
EAUM2050
Multi-function display The multi-function display is equipped
with the following:

an odometer (which shows the to-
tal distance traveled)


two tripmeters (which show the
distance traveled since they were
last set to zero, the time passed
since the tripmeters were set to ze-
ro, and the average speed traveled
during this time)


a fuel reserve tripmeter (which
shows the distance traveled since
the fuel level warning light came
on)

recommended final transmission
oil, and then install and tighten the
oil filler cap.
WARNING
EWA11310


Make sure that no foreign mate-
rial enters the final transmission
case.


Make sure that no oil gets on thetire or wheel.
7. Check the final transmission case
for oil leakage. If oil is leaking,
check for the cause.
EAU20070
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.
EAUM2101
To check the coolant level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.NOTE:

The coolant level must be checked
on a cold engine since the level
varies with engine temperature.


Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to theside can result in a false reading.
2. Check the coolant level through
the check window.
NOTE:The coolant should be between theminimum and maximum level marks.3. If the coolant is at or below the
minimum level mark, remove the
cowling A. (See page 6-5.)
4. Open the reservoir cap, and then
add coolant to the maximum level
mark.
Recommended final transmission
oil:
See page 8-1.

CAUTION:
ECA10471


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 not
be protected against frost and
corrosion.


If water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possible,
otherwise the effectiveness ofthe coolant will be reduced.WARNING
EWA10380
Never attempt to remove the radiatorcap when the engine is hot.
5. Close the reservoir cap, and then
install the cowling.
EAU33030
Changing the coolant
WARNING
EWA10380
Never attempt to remove the radiatorcap when the engine is hot.
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.
EAUS1333
Air filter and V-belt case air fil-
ter elements The air filter element should be re-
placed and the V-belt case air filter ele-
ment should be cleaned at the intervals
specified in the periodic maintenance
and lubrication chart. Service the air fil-
ter elements more frequently if you are
riding in unusually wet or dusty areas.
Replacing the air filter element
1. Place the scooter on the center-
stand.
2. Remove the air filter case cover by
removing the screws.

6 Engine overheating
WARNING
EWA10400


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.


After removing the radiator cap retaining bolt, place a thick rag, like a towel, over the radiator cap, and then
slowly rotate the cap counterclockwise to the detent to allow any residual pressure to escape. When the hissingsound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.
NOTE:If coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended coolantas soon as possible.
Wait until the
engine has cooled.
Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer checkand repair the cooling system.Add coolant. (See NOTE.)
Start the engine. If the engine overheats again,
have a
Yamaha dealer check
and repair the cooling system.
There is
leakage.
There is
no leakage.
