Brake pedalThe brake pedal is located on the right
side of the motorcycle. To apply the
rear brake, press down on the brake
pedal.

ABSThe Yamaha ABS (Anti-lock Brake
System) features a dual electronic con-
trol system, which acts on the front and
rear brakes independently.
Operate the brakes with ABS as you
would conventional brakes. If the ABS
is activated, a pulsating sensation may
be felt at the brake lever or brake pedal.
In this situation, continue to apply the
brakes and let the ABS work; do not
“pump” the brakes as this will reduce
braking effectiveness.
WARNING
EWA16051
Always keep a sufficient distance
from the vehicle ahead to match the
riding speed even with ABS.
The ABS performs best with
long braking distances.
On certain surfaces, such as
rough or gravel roads, the brak-
ing distance may be longer withthe 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 “clicking”
noise can be heard from the hy-
draulic control unit, and if the brake
lever or brake pedal is even slight-
ly applied, a vibration can be felt at
the lever and pedal, but these do
not indicate a malfunction.
This ABS has a test mode which
allows the owner to experience the
pulsation at the brake lever or
brake pedal when the ABS is oper-
ating. However, special tools are
required, so please consult yourYamaha dealer.
NOTICE
ECA20100
Be careful not to damage the wheel
sensor or wheel sensor rotor; other-
wise, improper performance of theABS will result.

stopped.
When the key is turned to “ON”,
traction control is turned on and
set to TCS “1” or “2” (whichever
was last selected).
Turn the traction control system off
to help free the rear wheel if the ve-
hicle gets stuck in mud, sand, orother soft surfaces.
NOTICE
ECA16801
Use only the specified tires. (See
page 6-15.) Using different sized
tires will prevent the traction control
system from controlling tire rotationaccurately.
Resetting the traction control sys-
tem
The traction control system will auto-
matically disable when:
the front wheel or rear wheel
comes off the ground while riding.
excessive rear wheel spin is de-
tected while riding.
either wheel is rotated with the key
turned to “ON” (such as when per- forming maintenance).
If the traction control system is dis-
abled, both the “ ” indicator light and
the “ ” warning light will come on.
Should this occur, try resetting the sys-
tem as follows. 1. Stop the vehicle and turn the key to “OFF”.
2. Wait a few seconds and then turn key back “ON”.
3. The “ ” indicator light should turn off and the system be enabled.
TIPIf the “ ” indicator light remains on af-
ter resetting, the vehicle may still be rid-
den; however, have a Yamaha dealercheck the vehicle as soon as possible.
4. Have a Yamaha dealer check the vehicle and turn off the “ ” warn-
ing light.

WARNING
EWA11092
Make sure that the fuel tank cap is
properly closed after filling fuel.Leaking fuel is a fire hazard.
EAU13222
FuelMake sure there is sufficient gasoline in
the tank.
WARNING
EWA10882
Gasoline and gasoline vapors are
extremely flammable. To avoid fires
and explosions and to reduce the
risk of injury when refueling, followthese 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 spilled fuel with a clean, dry,
soft cloth, since fuel may deteri-
orate painted surfaces or plastic
parts.
[ECA10072]
4. Be sure to securely close the fuel tank cap.
WARNING
EWA15152
Gasoline is poisonous and can
cause injury or death. Handle gaso-
line with care. Never siphon gaso-
line by mouth. If you should swallow

check each hose connection.
check each hose for damage. Re-
place if necessary.
confirm the end of each hose is not
blocked. Clean if necessary.
confirm that each hose is routed
through the clamp.

Catalytic converterThis model is equipped with a catalytic
converter in the exhaust system.
WARNING
EWA10863
The exhaust system is hot after op-
eration. To prevent a fire hazard or
burns:
Do not park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.
Park the vehicle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.
Make sure that the exhaust sys-
tem has cooled down before do-
ing any maintenance work.
Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up ofheat.
NOTICE
ECA10702
Use only unleaded gasoline. The use
of leaded gasoline will cause unre- pairable damage to the catalytic
converter.

CanisterThis model is equipped with a canister
to prevent the discharging of fuel vapor
into the atmosphere. Before operating
this vehicle, make sure to check the fol-
lowing:

Engine oilThe engine oil level should be checked
regularly. In addition, the oil must be
changed and the oil filter cartridge re-
placed at the intervals specified in the
periodic maintenance chart.NOTICE
ECA11621
In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a high-
er quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.
Make sure that no foreign mate-rial enters the crankcase. To check the engine oil level
1. After warming up the engine, wait a few minutes for the oil to settle.
2. With the vehicle on a level surface, hold it upright for an accurate read-
ing.
3. Look at the check window located at the bottom-right side of the
crankcase.
TIPThe engine oil should be between theminimum and maximum level marks.
4. If the engine oil is at or below the minimum level mark, remove the

Checking the br ake lever free
playThere should be no free play at the
brake lever end. If there is free play,
have a Yamaha dealer inspect the
brake system.
WARNING
EWA14212
A soft or spongy feeling in the brake
lever can indicate the presence of air
in the hydraulic system. If there is air
in the hydraulic system, have a
Yamaha dealer bleed the system be-
fore operating the vehicle. Air in the
hydraulic system will diminish the
braking performance, which may re- sult in loss of control and an acci-
dent.
EAU36505
Brake light switchesThe brake light should come on just be-
fore braking takes effect. The brake
light is activated by switches connected
to the brake lever and brake pedal.
Since the brake light switches are com-
ponents of the anti-lock brake system,
they should only be serviced by a
Yamaha dealer.

WARNING
EWA16011
Improper maintenance can result in
loss of braking ability. Observe
these precautions:
Insufficient brake fluid may al-
low air to enter the brake sys-
tem, reducing braking
performance.
Clean the filler cap before re-
moving. Use only DOT 4 brake
fluid from a sealed container.
Use only the specified brake flu-
id; otherwise, the rubber seals may deteriorate, causing leak-
age.
Refill with the same type of
brake fluid. Adding a brake fluid
other than DOT 4 may result in a
harmful chemical reaction.
Be careful that water or dust
does not enter the brake fluid
reservoir when refilling. Water
will significantly lower the boil-
ing point of the fluid and may re-
sult in vapor lock, and dirt may
clog the ABS hydraulic unitvalves.
NOTICE
ECA17641
Brake fluid may damage painted sur-
faces or plastic parts. Always cleanup spilled fluid immediately.
As the brake pads wear, it is normal for
the brake fluid level to gradually go
down. A low brake fluid level may indi-
cate worn brake pads and/or brake sys-
tem leakage; therefore, be sure to
check the brake pads for wear and the
brake system for leakage. If the brake
fluid level goes down suddenly, have a
Yamaha dealer check the cause before
further riding.
