EAU12171
Coolant temperature gauge With the key in the “ON” 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 6-29.)CAUTION:
ECA10020
Do not operate the engine if it isoverheated.
EAUM2250
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)


a clock


an ambient temperature display


an oil change indicator (which
comes on when the engine oil
should be changed)
NOTE:

For the UK, the distance traveled
is displayed in miles and the tem-
perature reading is displayed in °F.


For other countries, the distance
traveled is displayed in kilometers
and the temperature reading is dis-played in °C.
Odometer and tripmeter modes
Pushing the “MODE” button switches
the display between the odometer
mode “Total” and the tripmeter modes
“Trip” in the following order:
Total → Trip 1 → Trip 2 → Trip/fuel →

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.
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.

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.

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.3. Pull the air filter element out.
4. Insert a new air filter element into
the air filter case.
5. Install the air filter case cover by in-
stalling the screws.
