SAFETY INFORMATION
EAU10260
SCOOTERS ARE SINGLE TRACK
VEHICLES. THEIR SAFE USE AND
OPERATION ARE DEPENDENT
UPON THE USE OF PROPER
RIDING TECHNIQUES AS WELL AS
THE EXPERTISE OF THE OPERA-
TOR. EVERY OPERATOR SHOULD
KNOW THE FOLLOWING REQUIRE-
MENTS BEFORE RIDING THIS
SCOOTER.
HE OR SHE SHOULD:

OBTAIN THOROUGH INSTRUC-
TIONS FROM A COMPETENT
SOURCE ON ALL ASPECTS OF
SCOOTER OPERATION.

OBSERVE THE WARNINGS
AND MAINTENANCE REQUIRE-
MENTS IN THE OWNER’S MAN-
UAL.

OBTAIN QUALIFIED TRAINING
IN SAFE AND PROPER RIDING
TECHNIQUES.

OBTAIN PROFESSIONAL TECH-
NICAL SERVICE AS INDICATED
BY THE OWNER’S MANUAL
AND/OR WHEN MADE NECES-SARY BY MECHANICAL CONDI-
TIONS.
Safe riding

Always make pre-operation
checks. Careful checks may help
prevent an accident.

This scooter is designed to carry
the operator and passenger.

The failure of motorists to detect
and recognize scooters in traffic is
the predominating cause of auto-
mobile/scooter accidents. Many
accidents have been caused by an
automobile driver who did not see
the scooter. Making yourself con-
spicuous appears to be very effec-
tive in reducing the chance of this
type of accident.

Therefore:

Wear a brightly colored jacket.

Use extra caution when ap-
proaching and passing through
intersections, since intersec-
tions are the most likely places
for scooter accidents to occur.

Ride where other motorists cansee you. Avoid riding in another
motorist’s blind spot.

Many accidents involve inexperi-
enced operators. In fact, many op-
erators who have been involved in
accidents do not even have a cur-
rent driver’s license.

Make sure that you are qualified
and that you only lend your
scooter to other qualified opera-
tors.

Know your skills and limits.
Staying within your limits may
help you to avoid an accident.

We recommend that you prac-
tice riding your scooter where
there is no traffic until you have
become thoroughly familiar with
the scooter and all of its con-
trols.

Many accidents have been caused
by error of the scooter operator. A
typical error made by the operator
is veering wide on a turn due to
EXCESSIVE SPEED or undercor-
nering (insufficient lean angle for

Multi-function display
WARNING

EWA12311
Be sure to stop the vehicle before
making any setting changes to the
multi-function display.
The multi-function display is equipped
with the following:

a fuel meter

a coolant temperature meter

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 since
the bottom segment of the fuel
meter and fuel level warning sym-bol started flashing)

a self-diagnosis device

a clock

an ambient temperature display

an oil change indicator

a V-belt replacement indicator
NOTE:


Be sure to turn the key to “ON” be-
fore using the “SELECT” and “RE-
SET” 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
circuit.
Odometer and tripmeter modes
Pushing the “SELECT” button switches
the display between the odometer
mode “ODO” and the tripmeter modes
“TRIP” in the following order:
ODO

fuel meter and fuel level warning sym-
bol will start flashing, and the display
will automatically change to the fuel re-
serve tripmeter mode “TRIP F” and
start counting the distance traveled
from that point. In that case, pushing
the “SELECT” button switches the dis-
play between the various tripmeter and
odometer modes in the following order:

push the “RESET” button for at least
one second. If you do not reset the fuel
reserve tripmeter manually, it will resetitself automatically and the display will
return to the prior mode after refueling
and traveling 5 km (3 mi).
Fuel meter
With the key in the “ON” position, the
fuel meter indicates the amount of fuel
in the fuel tank. The display segments
of the fuel meter disappear towards “E”
(Empty) as the fuel level decreases.
When the fuel level reaches the bottom
segment is left near “E”, the fuel level
warning symbol and the bottom seg-
ment will flash. Refuel as soon as pos-
sible.
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 chang-
es in the weather and engine load. If
the top segment and coolant tempera-
ture symbol flash, stop the vehicle and
let the engine cool. (See page 6-37.)
CAUTION:

ECA10020
Do not operate the engine if it is
overheated.
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 en-
gine oil should be changed.
After changing the engine oil, reset the
oil change indicator. (See page 6-12.)
