Fuel gaugeThe fuel gauge indicates the amount of
fuel in the fuel tank. The needle moves
towards “E” (Empty) as the fuel level
decreases. When the needle reaches
the red zone, refuel as soon as possi-
ble.
When the key is turned to “ON”, the fuel
gauge needle will sweep once to test
the electrical circuit.
EAUT4230
Multi-function display
WARNING
EWA14432
Be sure to stop the vehicle before
making any setting changes to the
multi-function display. Changing
settings while riding can distract the
operator and increase the risk of anaccident.
The multi-function display is equippedwith the following:

a speedometer

an odometer

a tripmeter (which shows the dis-
tance traveled since it was last set
to zero)

an oil change tripmeter (which
shows the distanc
e traveled since
the last engine oil change)

an oil change indicator (which
flashes when the engine oil should
be changed)

a clock
TIPBe sure to turn the key to “ON” before
using the “SELECT” and “RESET” but-tons.
Odometer, tripmeter and oil change
tripmeter modes
Pushing the “SELECT” button switches
the display among the odometer mode
“ODO”, the tripmeter mode “TRIP” and
the oil change tripmeter “OIL
CHANGE” in the following order:
ODO → TRIP → OIL CHANGE →

TIPIf the odometer, tripmeter, or oil change
tripmeter indicates “-----”, have a Yama-
ha dealer check the multi-function dis-play.
OdometerTIPFor the U.K.: The odometer and tripme-
ter units can be switched from kilome-
ters to miles by pushing the “SELECT”button for 1 second.
Tripmeter
To reset the tripmeter, select it by push-
ing the “SELECT” button until “TRIP” isdisplayed, and then push the “RESET”
button for 1 second.
Oil change tripmeter
To reset the oil change tripmeter, select
it by pushing the “SELECT” button until
the oil change tripmeter is displayed,
and then push the “RESET” button for
3 seconds.
Push the “SELECT” button again to
start the oil change tripmeter; the dis-
play changes to the ODO mode.
Oil change indicator “OIL
CHANGE”
This indicator flashes at the initial 1000
km (600 mi), then at every 3000 km
(1800 mi) thereafter to indicate that the
engine oil should be changed.
After changing the engine oil, reset the
oil change tripmeter.
If the engine oil is changed before the
oil change indicator flashes (i.e. before
the periodic oil change interval has
been reached), the oil change tripmeter
must be reset after the oil change for
the next periodic oil change to be indi-
cated at the correct time.1. Odometer

Clock
To set the clock:1. Set the display to “ODO”, thenpress the “RESET” button for at
least three seconds.
2. When the hour digits start flashing, push the “SELECT” button to set
the hours.
3. Push the “RESET” button, and the first minute digit will start flashing.
4. Push the “SELECT” button to set the first minute digit.
5. Push the “RESET” button and the second minute digit will start flash-
ing.
6. Push the “SELECT” button to set the second minute digit.
7. Push the “RESET” button to start the clock.
TIPIf you do not push the “SELECT” or the
“RESET” button within 30 seconds, the
setting of the clock will not be complet-
ed and the display will change to “ODO”mode.

TIP
Air filter and V-belt filter
This model’s air filter is equipped with a disposable oil-coated paper elemen t, which must not be cleaned with com-
pressed air to avoid damaging it.
The air filter element needs to be replaced and V-belt filter needs to be serviced more frequently when riding in un- usually wet or dusty areas.

Hydraulic brake service
After disassembling the brake master cylinder and caliper , always change the fluid. Regularly check the brake fluid
level and fill the reservoir as required.
Every two years replace the internal components of the brake master cylinder and caliper, and change the brake fluid. Replace the brake hose every four years and if cracked or damaged.

erosion and excessive carbon or
other deposits, and replace it if
necessary.
To install the spark plug 1. Measure the spark plug gap with a wire thickness gauge and, if nec-
essary, adjust the gap to specifica-
tion.
2. Clean the surface of the spark plug gasket and its mating surface, and
then wipe off any grime from the spark plug threads.
3. Install the spark plug with the spark plug wrench, and then tight-
en it to the specified torque.
TIPIf 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. However, the spark
plug should be tightened to the speci-fied torque as soon as possible.
4. Install the spark plug cap.
5. Install the panel.
EAUT4160
Engine oil and 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 engine oil level1. Place the scooter 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.
