3 Self-diagnosis device
This model is equipped with a self-di-
agnosis device for various electrical
circuits.
If a problem is detected in any of those
circuits, the engine trouble warning
light will come on and the display will
indicate an error code.
If the display indicates any error codes,
note the code number, and then have a
Yamaha dealer check the vehicle.
Coolant temperature meter
With the key in the “ON” position, the
coolant temperature meter indicates
the temperature of the coolant. The
coolant temperature varies with
changes in the weather and engine
load. If the top segment and coolant
temperature warning indicator flash,
stop the vehicle and let the engine
cool.NOTICE
ECA10022
Do not continue to operate the en-
gine if it is overheating.

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.
EAUM3045To check the coolant level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.
2. Open the front storage compart-
ment A. (See page 3-21.)
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.
3. Check the coolant level through
the check window.
TIP
The coolant should be between the
minimum and maximum level marks.
4. If the coolant is at or below the
minimum level mark, remove pan-
el A. (See page 6-7.)
5. Open the reservoir cap, and then
add coolant to the maximum level
mark. 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 not
be 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]

install the panel.1. Maximum level mark

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.
 [EWA10382]EAUM3370
Air filter and V-belt case air fil-
ter elements and check hoses
The 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.
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
installing the screws.
To clean the air filter check hoses
1. Check the hoses at the bottom of
air filter case for accumulated dirt
or water.

6Engine 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.
