Safety information
1-3
1 any engine exhaust. Deadly levels of
carbon monoxide can collect rapidly
and you can quickly be overcome and
unable to save yourself. Also, deadly
levels of carbon monoxide can linger
for hours or days in enclosed or poorly
ventilated areas. If you experience any
symptoms of carbon monoxide poi-
soning, leave the area immediately, get
fresh air, and SEEK MEDICAL TREAT-
MENT.
Do not run engine indoors. Even if
you try to ventilate engine exhaust
with fans or open windows and
doors, carbon monoxide can rap-
idly reach dangerous levels.
Do not run engine in poorly venti-
lated or partially enclosed areas
such as barns, garages, or car-
ports.
Do not run engine outdoors where
engine exhaust can be drawn into
a building through openings such
as windows and doors.
Loading
Adding accessories or cargo to your
scooter can adversely affect stability
and handling if the weight distribution
of the scooter is changed. To avoid the
possibility of an accident, use extreme
caution when adding cargo or acces-
sories to your scooter. Use extra care
when riding a scooter that has added
cargo or accessories. Here, along with
the information about accessories be-
low, are some general guidelines to fol-
low if loading cargo to your scooter:The total weight of the operator, pas-
senger, accessories and cargo must
not exceed the maximum load limit.
Operation of an overloaded vehicle
could cause an accident.
When loading within this weight limit,
keep the following in mind:
Cargo and accessory weight
should be kept as low and close to
the scooter as possible. Securely
pack your heaviest items as close
to the center of the vehicle as pos-
sible and make sure to distribute
the weight as evenly as possible
on both sides of the scooter to
minimize imbalance or instability.
Shifting weights can create a sud-
den imbalance. Make sure that
accessories and cargo are se-
curely attached to the scooter be-
fore riding. Check accessory
mounts and cargo restraints fre-
quently.
• Properly adjust the suspension
for your load (suspension-ad-
justable models only), and
check the condition and pres-
sure of your tires.
• Never attach any large or heavy
items to the handlebar, front
fork, or front fender. Such items
can create unstable handling or
a slow steering response.
This vehicle is not designed to
pull a trailer or to be attached to
a sidecar.
Maximum load:
184 kg (406 lb)

US gal, 0.53 Imp.gal) of fuel re-
mains in the fuel tank, the last seg-
ment of the fuel meter will start
flashing. The display will automat-
ically change to the fuel reserve
tripmeter “F Trip” and start count-
ing the distance traveled from that
point.
Coolant temperature meter
The coolant temperature meter indi-
cates the temperature of the coolant.
If the top segment flashes, stop the ve-
hicle, then stop the engine, and let the
engine cool. (See page 7-34.)
NOTICE

Do not continue to operate the en-
gine if it is overheating.
TIP
If a problem is detected in the
coolant temperature meter, all
segments will flash repeatedly. If
this occurs, have a Yamaha dealer
check the vehicle as soon as pos-
sible.
The coolant temperature varies
with changes in the weather and
engine load.
Tripmeter display
The tripmeter display is equipped with
the following:
odometer
tripmeter
time tripmeter

ments.
The icy road warning indicator “ ” will

control is automatically turned on.
To turn the traction control system off,
use the “INFO” switch to change the
information display to the traction con-
trol system display. Then push the “IN-
FO” switch for three seconds. The

Turn the traction control system off to
help free the rear wheel if the vehicle
gets stuck in mud, sand, or other soft
surfaces.
NOTICE
ECA16801
Use only the specified tires. (See
page 7-16.) Using different sized
tires will prevent the traction control
system from controlling tire rotation
accurately.
Resetting the traction control sys-
tem
The traction control system will auto-
matically disable under certain condi-
tions; such as when a sensor fault is
detected, or when only one wheel is al-
lowed to rotate for more than a fewseconds. Should this happen, the “ ”
indicator light will come on, and possi-
bly the “ ” warning light, too.
TIP
When the vehicle is on the centerstand,
do not rev the engine for an extended
period of time. Otherwise, the traction
control system will automatically dis-
able and need to be reset.
If the traction control system automat-
ically disables, try resetting it as fol-
lows.
1. Stop the vehicle and turn it off
completely.
2. Wait a few seconds and then turn
the vehicle power on.
3. The Ž indicator light should
turn off and the system be en-
abled.
TIP
If the Ž indicator light remains on af-
ter resetting, the vehicle may still be
ridden; however, have a Yamaha deal-
er check the vehicle as soon as possi-
ble.
4. Have a Yamaha dealer check the
vehicle and turn off the Ž
warning light.

TIP
This mark identifies the recom-
mended fuel for this vehicle as
specified by European regulation
(EN228).
 Check that gasoline nozzle has
the same identifier when fueling.
Your Yamaha engine has been de-
signed to use premium unleaded gas-
oline with a research octane number of
95 or higher. If knocking (or pinging)
occurs, use a gasoline of a different
brand. Use of unleaded fuel will extend
spark plug life and reduce mainte-
nance costs.
Gasohol
There are two types of gasohol: gaso-
hol containing ethanol and that con-
taining methanol. Gasohol containing
ethanol can be used if the ethanol con-
tent does not exceed 10% (E10). Gas-
ohol containing methanol is not
recommended by Yamaha because it
can cause damage to the fuel system
or vehicle performance problems.
EAU58301
Fuel tank overflow hose
Before operating the vehicle:
 Check the fuel tank overflow hose
connection and routing.
 Check the fuel tank overflow hose
for cracks or damage, and replace
it if necessary.
 Make sure that the fuel tank over-
flow hose is not blocked, and
clean it if necessary.
