4. Oil change indicator “OIL”
The multi-function display is equip-
ped with the following:
a fuel meter
a coolant temperature meter
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 sin-
ce the bottom segment of the
fuel meter and fuel level warning
indicator started flashing)
a self-diagnosis device
a clock
an ambient temperature display
an oil change indicator
a V-belt replacement indicator
TIP
Be sure to turn the key to “ON”
before 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
and then disappear, in order to
test the electrical circuit.
Odometer and tripmeter modes
Pushing the “SELECT” button swit-
ches the display between the odome-
ter mode “Odo” and the tripmeter
modes “Trip” in the following order:
Odo/Trip (top) Trip (bottom)/Trip
(top) Odo/Trip (top)When approximately 2.0 L (0.53 US
gal, 0.44 Imp.gal) of fuel remains in
the fuel tank, the bottom segment of
the fuel meter and fuel level warning
indicator will start flashing, and the
display will automatically change to
the fuel reserve tripmeter mode “Trip
F” and start counting the distance tra-
veled from that point. In that case,
pushing the “SELECT” button swit-
ches the display between the various
tripmeter and odometer modes in the
following order:
Trip F/Trip (top) Trip (bottom)/Trip
(top) Odo/Trip (top) Trip F/Trip
(top)

1. Fuel reserve tripmeter
To reset a tripmeter, select it by pus-
hing the “SELECT” button until “Trip”
or “Trip F” begins flashing (“Trip” or
“Trip F” will only flash for five
seconds). While “Trip” or “Trip F” is
flashing, push the “RESET” button for
at least one second. If you do not
reset the fuel reserve tripmetermanually, it will reset itself automati-
cally and the display will return to the
prior mode after refueling and trave-
ling 5 km (3 mi).
TIP
The display cannot be changed back
to “Trip F” after pushing the “RESET”
button.
Fuel meter
With the key in the “ON” position, the
fuel meter indicates the amount of
fuel in the fuel tank. The display seg-
ments of the fuel meter disappear
towards “E” (Empty) as the fuel level
decreases. When the fuel level rea-
ches the bottom segment near “E”,
the fuel level warning indicator and
the bottom segment will flash. Refuel
as soon as possible.
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 chan-
ges in the weather and engine load. Ifthe top segment and coolant tempe-
rature warning indicator flash, stop
the vehicle and let the engine cool.
(See page 6-32).
ECA10021
Do not continue to operate the
engine if it is overheating.
Oil change indicator “OIL”
This indicator flashes at the initial
1000 km (600 mi), then at 4000 km
(2500 mi) and every 3000 km (1800
mi) thereafter to indicate that the
engine oil should be changed.
After changing the engine oil, reset
the oil change indicator. (See page
6-10).

TIP
Engine air filter and V-belt air filter
This model’s engine air filter is equipped with a disposable oil-coated paper element, which must not be cleaned
with compressed air to avoid damaging it.
The engine air filter element needs to be replaced and the V-belt air filter element needs to be serviced more fre-
quently when riding in unusually wet or dusty areas.
Hydraulic brake service
After disassembling the brake master cylinders and calipers, always change the fluid. Regularly check the brake
fluid levels and fill the reservoirs as required.
Every two years replace the internal components of the brake master cylinders and calipers, and change the bra-
ke fluid.
Replace the brake hoses every four years and if cracked or damaged.
TIP
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is
1/4–1/2 turn past finger tight. Howe-
ver, the spark plug should be tighte-
ned to the specified torque as soon
as possible.
EAUS1711
Engine oil
The engine oil level should be chec-
ked before each ride. In addition, the
oil must be changed at the intervals
specified in the periodic maintenance
and lubrication chart and when the
service indicator light comes on.
To check the engine oil level
1. Place the scooter on the centers-
tand. 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
settles, remove the oil filler cap,
wipe the dipstick clean, insert it
back into the oil filler hole (wit-
hout screwing it in), and then
remove it again to check the oil
level.
TIP
The engine oil should be between the
minimum and maximum level marks.
1. Engine oil filler cap
2. Maximum level mark
3. Minimum level mark
4. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to rai-
se it to the correct level.
5. Insert the dipstick into the oil filler
hole, and then tighten the oil filler
cap.
To change the engine oil
1. Start the engine, warm it up for
several minutes, and then turn it
off.
2. Place an oil pan under the engine
to collect the used oil.

6. Install the final transmission oil
drain bolt and its new gasket,
and then tighten the bolt to the
specified torque.

7. Refill with the specified amount
of the recommended final trans-
mission oil. WARNING! Make
sure that no foreign material
enters the final transmission
case. Make sure that no oil
gets on the tire or wheel.
[EWA11311]
8. Install the final transmission oil
filler cap and its new O-ring, and
then tighten the oil filler cap.
9. 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 coo-
lant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAUS1670
To check the coolant level
1. Place the vehicle on a level surfa-
ce and hold it in an upright posi-
tion.
TIP
The coolant level must be chec-
ked on a cold engine since the
level varies with engine tempera-
ture.
Make sure that the vehicle is
positioned 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.
