L/100 km: The number of seg-
ments displayed decreases the
more efficiently the vehicle is be-
ing operated.
Multi-function display
The multi-function display is equipped
with the following:  an odometer
 two tripmeters (which show the
distance traveled since they were
last set to zero)
 a fuel reserve tripmeter (which
shows the distance traveled since
the last segment of the fuel meter
started flashing)
 an instantaneous fuel consump-
tion display 
an average fuel consumption dis-
play
 an oil change tripmeter
 a V-belt replacement tripmeter
 an oil change indicator
 a V-belt replacement indicator
 an error code display
Except for the UK:
Push the “SELECT” button to switch
the display between the odometer
mode “ODO”, tripmeter modes “TRIP
1” and “TRIP 2”, oil change tripmeter
mode “OIL TRIP”, V-belt replacement
tripmeter mode “V-BELT TRIP”, in-
stantaneous fuel consumption mode
“F/ECO” (km/L or L/100 km), and aver-
age fuel consumption mode “AVE
F/ECO” (km/L or L/100 km) in the fol-
lowing order:
ODO → TRIP 1 → TRIP 2 → OIL TRIP
→ V-BELT TRIP → F/ECO → AVE
F/ECO → ODO
For the UK:Push the “SELECT” button to switch
the display between the odometer
mode “ODO”, tripmeter modes “TRIP 1” and “TRIP 2”, oil change tripmeter
mode “OIL TRIP”, V-belt replacement
tripmeter mode “V-BELT TRIP”, in-
stantaneous fuel consumption mode
“F/ECO” (MPG or L/100 km), and aver-
age fuel consumption mode “AVE
F/ECO” (MPG or L/100 km) in the fol-
lowing order:
ODO
→ TRIP 1 → TRIP 2 → OIL TRIP
→ V-BELT TRIP → F/ECO → AVE
F/ECO → ODO
If the fuel level warning indicator “ ”
and last segment of the fuel meter start
flashing, the display automatically
changes to the fuel reserve tripmeter
mode “TRIP F” and starts counting the
distance traveled from that point. In
that case, push the “SELECT” button
to switch the display between the vari-
ous tripmeter, odometer, oil change
tripmeter, V-belt replacement tripme-
ter, instantaneous fuel consumption
and average fuel consumption modes
in the following order:

“km/L”: The average distance that
can be traveled on 1.0 L of fuel is
shown.
 “L/100 km”: The average amount
of fuel necessary to travel 100 km
is shown.
 “MPG”: The average distance that
can be traveled on 1.0 lmp. gal of
fuel under the current riding condi-
tions is shown.
To switch between the average fuel
consumption display settings, push
the “SELECT” button for one second.
To reset the average fuel consumption,
push the “RESET” button for at least
one second.
TIP After resetting the average fuel
consumption, “_ _._” will be
shown until the vehicle has trav-
eled 0.1 km (0.06 mi).
 When MPG is selected, no units
indicator will be displayed.
Oil chan ge tripmeter mo de
The oil change tripmeter shows the
distance traveled since it was last reset
(i.e., since the last oil change).
The oil change indicator “OIL” will flash
at the initial 1000 km (600 mi), then at
6000 km (3500 mi) and every 6000 km
(3500 mi) thereafter to indicate that the
engine oil should be changed.
After changing the engine oil, reset the
oil change tripmeter and the oil change
indicator. To reset them both, select
the oil change tripmeter, and then push
the “RESET” button for one second.
Then, while “OIL” and the oil change tripmeter are flashing, push the “RE-
SET” button for three seconds. The oil
change indicator will be reset.
If the engine oil is changed before the
oil change indicator comes on (i.e., be-
fore the periodic oil change interval has
been reached), the oil change tripmeter
must be reset for the next periodic oil
change to be indicated at the correct
time.

En
gine oil an d oil strainerThe engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil strainer
cleaned at the intervals specified in the
periodic maintenance and lubrication
chart.
To check the en gine oil level
1. Place the vehicle on the center- stand. A slight tilt to the side can
result in a false reading.
2. Start the engine, warm it up for several minutes, and then turn it
off.
3. Wait a few minutes until the oil set- tles, remove the engine oil filler
cap, wipe the engine oil dipstick
clean, insert it back into the oil fill-
er hole (without screwing it in), and
then remove it again to check the
oil level. WARNING! The muffler
an d muffler protector become
very hot d uring use. To avoi d
possi ble burns, let the muffler
an d protector cool before re-
movin g the oil filler cap.
[EWA17810]
TIPThe engine oil should be between the
tip of the dipstick and the maximum
level mark.4. If the engine oil is not between the
tip of the dipstick and the maxi-
mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
5. Insert the dipstick into the oil filler hole, and then tighten the oil filler
cap.

8. Start the engine, and then let it idle for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.
9. Turn the engine off, and then check the oil level and correct it if
necessary.
10. Reset the oil change tripmeter and oil change indicator “OIL”. (See
page 3-6 for reset procedures.)

Final transmission oilThe final transmission case must be
checked for oil leakage before each
ride. If any leakage is found, have a
Yamaha dealer check and repair the scooter. In addition, the final transmis-
sion oil must be changed as follows at
the intervals specified in the periodic
maintenance and lubrication chart. 1. Start the engine, warm up the final transmission oil by riding the
scooter for several minutes, and
then stop the engine.
2. Place the scooter on the center- stand.
3. Place an oil pan under the final transmission case to collect the
used oil.
4. Remove the final transmission oil filler cap and its O-ring from the fi-
nal transmission case. 5. Remove the final transmission oil
drain bolt and its gasket to drain
the oil from the final transmission
case.

7. Refill with the specified amount of the recommended final transmis-
sion oil. WARNING! Make sure
that no forei gn material enters
the final transmission case.
Make sure that no oil gets on
the tire or wheel.

CoolantThe 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.
EAUN1090
To check the coolant level1. 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.TIPThe coolant should be between the
minimum and maximum level marks.
3. If the coolant is at or below theminimum level mark, remove the
right floorboard mat by pulling it
up.
