ABSThe anti-lock brake system (ABS) acts
on the front and rear brakes indepen-
dently.
WARNING
EWA16051
Always keep a sufficient d istance
from the vehicle ahead to match the
ri din g speed 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.How to operate the brakes
Operate the brake lever and brake
pedal the same as you would conven-
tional brakes. If wheel slip is detected
while braking, ABS will activate and a
pulsating sensation may be felt at the
brake lever or brake pedal. Continue to
apply the brakes and let the ABS work.
Do not pump the brakes as this will re-
duce braking effectiveness. 
The ABS performs a self-check
when you first start off. During this
time a clicking noise from the hy-
draulic unit may be audible, and if
the brake lever or brake pedal is
applied a vibration can be felt, but
this is not a malfunction.
 The brake system will revert to a
conventional brake system in case
of ABS malfunction.
NOTICE

sensor or wheel sensor rotor; other-
wise, improper performance of the

Traction control systemThe traction control system (TCS)
helps maintain traction when acceler-
ating on slippery surfaces, such as un-
paved or wet roads. If sensors detect
that the rear wheel is starting to slip
(uncontrolled spinning), the traction
control system assists by regulating
engine power until traction is restored.
When traction control has engaged,
the “ ” indicator light will flash. You
may notice changes in engine re-
sponse or exhaust sound.
WARNING
EWA18860
The traction control system is not a
su bstitute for ri din g appropriately
for the con ditions. Traction control
cannot prevent loss of traction d ue
to excessive spee d when enterin g
turns, when acceleratin g har d at a
sharp lean an gle, or while b raking,
an d cannot prevent front wheel slip-
pin g. As with any vehicle, approach
surfaces that may be slippery with
caution an d avoi d especially slip-
pery surfaces.
Settin g the traction control system
When the vehicle is turned on, traction
control is automatically turned on.
To turn the traction control system off,
use the “SEL” switch to change the
multi-function display to the traction
control system display. Then push the
“RES” switch for three seconds. The
display will show “TCS OFF”, and
the “ ” indicator light will come on.
TIPTurn 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 specifie d tires. (See
pa ge 8-22.) Usin g different size d
tires will prevent the traction control
system from controllin g tire rotation
accurately.

5 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 few
seconds. Should this happen,
the “ ” indicator light will come on.
TIPWhen 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, reset it by riding under
normal conditions.TIPIf the Ž indicator light remains on
after resetting, the vehicle may still be
ridden; however, have a Yamaha deal-
er check the vehicle as soon as possi-
ble.

WARNING
EWA11092
Make sure that the fuel tank cap is
properly closed after filling fuel.
Leakin g fuel is a fire hazar d.
EAU13213
FuelMake sure there is sufficient gasoline in
the tank.
WARNING
EWA10882
Gasoline an d gasoline vapors are
extremely flammab le. To avoid fires
an d explosions an d to re duce the
risk of injury when refueling , 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. 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 painte d surfaces or
plastic parts.
[ECA10072]
4. Be sure to securely close the fuel tank cap.
WARNING

Gasoline is poisonous an d can
cause injury or death. Han dle gaso-
line with care. Never siphon gasoline

NOTICE
ECA11401
Use only unlea ded g asoline. The use
of lead ed 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.
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 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. 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.
Recommen
ded fuel:
Regular unleaded gasoline (E10 ac-
ceptable)
