SAFETY INFORMATION

1Carbon Monoxide is a colorless, odor-
less, tasteless gas which may be
present even if you do not see or smell
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. Loa

Adding accessories or cargo to your
vehicle can adversely affect stability
and handling if the weight distribution
of the vehicle is changed. To avoid the
possibility of an accident, use extreme
caution when adding cargo or acces-
sories to your vehicle. Use extra care
when riding a vehicle 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 vehicle:
The total weight of the operator, pas-
senger, accessories and cargo must
not exceed the maximum load limit.
Operation of an overloa ded vehicle
coul d cause an acci dent.
When loading within this weight limit,
keep the following in mind:  Cargo and accessory weight
should be kept as low and close to
the vehicle 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 vehicle 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 vehicle 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 desi gne d to
pull a trailer or to be attached to
a si decar.

specifications and more information on
replacing your tires.
Transportin
g the Vehicle
Be sure to observe the following in-
structions before transporting the vehi-
cle in another vehicle.  Remove all loose items from the
vehicle.
 Point the front wheels straight
ahead on the trailer or in the truck
bed, and choke it in a rail to pre-
vent movement.
 Secure the vehicle with tie-downs
or suitable straps that are at-
tached to solid parts of the vehi-
cle, such as the frame or upper
front fork triple clamp (and not, for
example, to rubber-mounted han-
dlebars or turn signals, or parts
that could break). Choose the lo-
cation for the straps carefully so
the straps will not rub against
painted surfaces during transport. 
The suspension should be com-
pressed somewhat by the tie-
downs, if possible, so that the ve-
hicle will not bounce excessively
during transport.
EAU60590
Further safe-ri din g points Be sure to signal clearly when
making turns.
 Braking can be extremely difficult
on a wet road. Avoid hard braking,
because the vehicle could slide.
Apply the brakes slowly when
stopping on a wet surface.
 Slow down as you approach a
corner or turn. Once you have
completed a turn, accelerate
slowly.
 Be careful when passing parked
cars. A driver might not see you
and open a door in your path.
 Railroad crossings, streetcar rails,
iron plates on road construction
sites, and manhole covers be-
come extremely slippery when
wet. Slow down and cross them
with caution. Keep the vehicle up-
right, otherwise it could slide out
from under you.
 The brake pads or linings could
get wet when you wash the vehi-
cle. After washing the vehicle,
check the brakes before riding.


Always wear a helmet, gloves,
trousers (tapered around the cuff
and ankle so they do not flap), and
a brightly colored jacket.
 Do not carry too much luggage on
the vehicle. An overloaded vehicle
is unstable. Use a strong cord to
secure any luggage to the carrier
(if equipped). A loose load will af-
fect the stability of the vehicle and
could divert your attention from
the road. (See page 1-3.)

TIPAs the unified brake system is me-
chanical, additional free play can
be felt in the front brake lever
when the rear brake lever is being
pulled.
 The unified brake system does not
function when the front brake is
applied alone.
EAUU1840
ABSYour leaning multi-wheel vehicle’s ABS
(Anti-lock Brake System) features an
electronic control system, which acts
on each of the front and rear brakes in-
dependently.
Operate the brakes with ABS as you
would conventional brakes. If the ABS
is activated, a pulsating sensation may
be felt at the brake levers. In this situa-
tion, continue to apply the brakes and
let the ABS work; do not “pump” the
brakes as this will reduce braking ef-
fectiveness.
WARNING
EWA16051
Always keep a sufficient d istance
from the vehicle ahea d to match the
ri din g spee d even with ABS.
 The ABS performs best with
lon g b rakin g d istances.
 On certain surfaces, such as
rou gh or g ravel roa ds, the b rak-
in g d istance may b e longer with
the ABS than without.The ABS is monitored by an ECU,
which will revert the system to conven-
tional braking if a malfunction occurs.
TIP The ABS performs a self-diagno-
sis test each time the vehicle first
starts off after the key is turned to
“ON” and the vehicle has traveled
at a speed of 10 km/h (6 mi/h) or
higher. During this test, a “click-
ing” noise can be heard from the
front of the vehicle, and if either
brake lever is even slightly ap-
plied, a vibration can be felt at the
lever, but these do not indicate a
malfunction.
 This ABS has a test mode which
allows the owner to experience
the pulsation at the brake levers
when the ABS is operating. How-
ever, special tools are required, so
please consult your Yamaha deal-
er.NOTICE

Be careful not to d amage the wheel
sensor or wheel sensor rotor; other-
wise, improper performance of the
ABS will result.

FuelMake sure there is sufficient gasoline in
the tank.
WARNING
EWA10882
Gasoline and g asoline vapors are
extremely flammab le. To avoid fires
an d explosions an d to re duce the
risk of injury when refuelin g, follow
these instructions.1. Before refueling, turn off the en- gine and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the vi-
cinity of sparks, open flames, or
other sources of ignition such as
the pilot lights of water heaters
and clothes dryers.
2. Do not overfill the fuel tank. When refueling, be sure to insert the
pump nozzle into the fuel tank filler
hole. Stop filling when the fuel
reaches the bottom of the filler
tube. Because fuel expands when
it heats up, heat from the engine or
the sun can cause fuel to spill out
of the fuel tank. 3. Wipe up any spilled fuel immedi-
ately. NOTICE: Immediately
wipe off spille d fuel with a clean,
d ry, soft cloth, since fuel may
d eteriorate painted surfaces or
plastic parts.
[ECA10072]
4. Be sure to securely close the fuel tank cap.
WARNING
EWA15152
Gasoline is poisonous an d can
cause injury or death. Han dle gaso-
line with care. Never siphon gasoline
b y mouth. If you shoul d swallow
some gasoline or inhale a lot of g as-
oline vapor, or g et some gasoline in
your eyes, see your doctor imme di- ately. If g
asoline spills on your skin,
wash with soap an d water. If gaso-
line spills on your clothin g, chan ge
your clothes.

Use only unlea ded g asoline. The use
of lea ded g asoline will cause severe
d amag e to internal en gine parts,
such as the valves an d piston rin gs,
as well as to the exhaust system.Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a research octane number of
95 or higher. If knocking (or pinging)
occurs, use a gasoline of a different
brand or premium unleaded fuel. Use
of unleaded fuel will extend spark plug
life and reduce maintenance costs.
