Coolant temperature gauge
With the key in the “ON” position, the
coolant temperature gauge indicates
the temperature of the coolant. When
the key is turned to “ON”, the coolant
temperature gauge needle will sweep
once across the temperature range and
then return to “C” in order to test the
electrical circuit. The coolant tempera-
ture varies with changes in the weather
and engine load. If the needle reaches
or enters the red zone, stop the vehicle
and let the engine cool. (See
page 6-35.)
CAUTION:

ECA10020
Do not operate the engine if it is
overheated.

The multi-function display is equipped
with the following:


a tachometer (which shows engine
speed)

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

two tripmeters (which show the
distance traveled since they were
last set to zero)

a fuel reserve tripmeter (which
shows the distance traveled when
the remaining fuel in the fuel tank
reaches approximately 3.0 L (0.79
US gal) (0.66 Imp.gal))

a self-diagnosis device

a clock

an oil change tripmeter (which
shows the distance traveled since
the last engine oil change)

a V-belt replacement tripmeter
(which shows the distance trav-
eled since the last V-belt replace-
ment)
NOTE:


Be sure to turn the key to “ON” be-
fore using the “SELECT” and
“RESET” buttons.

When the key is turned to “ON”, all
of the display segments of the
multi-function display will appear
one after the other and then disap-
pear, in order to test the electrical
circuits.
Tachometer
The tachometer allows the rider to
monitor the engine speed and keep it
within the ideal power range.
CAUTION:

9 Oil change indicator “OIL”
This indicator flashes at the initial 1000
km (600 mi), then at 5000 km (3000 mi)
and every 5000 km (3000 mi) thereafter
to indicate that the engine oil should be
changed.
After changing the engine oil, reset the
oil change indicator. To reset the oil
change indicator, select it by pushing
the “SELECT” button until “OIL Trip” is
displayed, and then push the “RESET”
button at least 1 second. When pushing
the “RESET” button, “OIL Trip” starts
flashing. While “OIL Trip” is flashing,
push the “RESET” button for at least 3
seconds.
If the engine oil is changed before theoil change indicator “OIL” flashes (i.e.
before the periodic oil change interval
has been reached), the indicator “OIL”
must be reset after the oil change for
the next periodic oil change to be indi-
cated at the correct time.
The electrical circuit of the indicator can
be checked according to the following
procedure.
1. Set the engine stop switch to “”
and turn the key to “ON”.
2. Check that the oil change indicator
comes on for a few seconds and
then goes off.
3. If the oil change indicator does not
come on, have a Yamaha dealer
check the electrical circuit.
V-belt replacement indicator
“V-BELT”
This indicator flashes every 20000 km
(12500 mi) when the V-belt needs to be
replaced.
After changing the V-belt, reset the
V-belt replacement indicator. To reset
the V-belt replacement indicator, select
it by pushing the “SELECT” button until
“V-BELT Trip” is displayed, and then
push the “RESET” button at least 1 sec-
ond. When pushing the “RESET” but-
ton, “V-BELT Trip” starts flashing.
While “V-BELT Trip” is flashing, push
the “RESET” button for at least 3 sec-
onds.

flashes (i.e. before the periodic V-belt
change interval has been reached), the
indicator “V-BELT” must be reset after
the V-belt change for the next periodic
V-belt change to be indicated at the
correct time.
The electrical circuit of the indicator can
be checked according to the following
procedure.
1. Turn the key to “ON” and make
sure that the engine stop switch is
set to “”.
2. If the V-belt replacement indicator
does not come on, have a Yamaha
dealer check the electrical circuit.
Self-diagnosis device
This model is equipped with a self-diag-
nosis device for various electrical cir-
cuits.
If any of those circuits are defective, the
engine trouble warning light will come
on, and then the display will indicate a
two-digit error code.
This model is also equipped with a
self-diagnosis device for the immobiliz-
er system.
If any of the immobilizer system circuits
are defective, the immobilizer system
indicator light will flash, and then the
display will indicate a two-digit error
code.
NOTE:

If the display indicates error code 52,
this could be caused by transponder in-
terference. If this error code appears,
try the following.
1. Use the code re-registering key to
start the engine.
NOTE:

Make sure there are no other immobi-
lizer keys close to the main switch, and
do not keep more than one immobilizer
key on the same key ring! Immobilizersystem keys may cause signal interfer-
ence, which may prevent the engine
from starting.
2. If the engine starts, turn it off and
try starting the engine with the
standard keys.
3. If one or both of the standard keys
do not start the engine, take the
vehicle, the code re-registering
key and both standard keys to a
Yamaha dealer and have the stan-
dard keys re-registered.
If the display indicates any error codes,
note the code number, and then have a
Yamaha dealer check the vehicle.
CAUTION:

ECA11590
If the display indicates an error
code, the vehicle should be checked
as soon as possible in order to avoid
engine damage.

CAUTION:

ECA11400
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,
as well as to the exhaust system.
Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a research octane number of
91 or higher. If knocking (or pinging) oc-
curs, use a gasoline of a different brand
or premium unleaded fuel. Use of un-
leaded fuel will extend spark plug life
and reduce maintenance costs.
EAU13431
Catalytic converter
This model is equipped with a catalytic
converter in the exhaust system.
WARNING

EWA10860
The exhaust system is hot after op-
eration. Make sure that the exhaust
system has cooled down before do-
ing any maintenance work.
CAUTION:

ECA10700
The following precautions must be
observed to prevent a fire hazard or
other damages.

Use only unleaded gasoline.
The use of leaded gasoline will
cause unrepairable damage to
the catalytic converter.

Never park the vehicle near pos-
sible fire hazards such as grass
or other materials that easily
burn.

Do not allow the engine to idle
too long.
EAU13932
Seat
To open the seat
1. Place the scooter on the center-
stand.
2. Insert the key into the main switch,
and then turn it counterclockwise
to “OPEN”.
NOTE:

Do not push inward when turning the
key.
3. Fold the seat up.

Ignition circuit cut-off system
The ignition circuit cut-off system (com-
prising the sidestand switch and brake
light switches) has the following func-
tions.

It prevents starting when the side-
stand is up, but neither brake is ap-
plied.

It prevents starting when either
brake is applied, but the sidestand
is still down.

It cuts the running engine when the
sidestand is moved down.
Periodically check the operation of the
ignition circuit cut-off system according
to the following procedure.
WARNING

EWA10250
If a malfunction is noted, have a
Yamaha dealer check the system be-
fore riding.
