Traction control systemThe traction control system helps
maintain traction when accelerating on
slippery surfaces, such as unpaved or
wet roads. If sensors detect that the
rear wheel is starting to slip (uncon-
trolled spinning), the traction control
system assists by regulating engine
power as needed until traction is re-
stored. The “TCS” indicator/warning
light flashes to let the rider know that
traction control has engaged.TIPThe rider may also notice slight chang-
es in engine and exhaust sounds when
the traction control system is engaged.
WARNING
EWA15432
The traction control system is not a
substitute for rid ing appropriately
for the con ditions. Traction control
cannot prevent loss of traction due
to excessive speed when entering
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 motorcycle, ap- proach surfaces that may
be
slippery with caution an d avoi d es-
pecially slippery surfaces.
When the key is turned to “ON”, the
traction control system automatically
turns on.
The traction control system can be
turned on or off manually only when
the key is in the “ON” position and the
motorcycle is stopped.TIPTurn the traction control system off to
help free the rear wheel if the motorcy-
cle gets stuck in mud, sand, or other
soft surfaces.NOTICE
ECA16801
Use only the specified tires. (See
pa ge 6-17.) Usin g different size d
tires will prevent the traction control
system from controllin g tire rotation
accurately.
Turnin g on/off the traction control
system
WARNING
EWA15441
Be sure to stop the vehicle before
makin g any settin g chan ges to the
traction control system. Chan gin g
settin gs while ri din g can distract the
operator an d increase the risk of an
acci dent.To turn off the traction control system,
push the “TCS” button on the multi-
function meter unit for at least 2 sec-
onds. The “TCS” indicator/warning
light will come on.
To turn on the traction control system,
push the “TCS” button again. The

Resettin g
The traction control system will be dis-
abled in the following conditions:  The rear wheel is rotated with the
centerstand down and the key in
the “ON” position.
 Either the front wheel or rear wheel
comes off the ground while riding.
 Excessive rear wheel spinning.
If the traction control system has been
disabled, both the “TCS” indica-
tor/warning light and the engine trou-
ble warning light come on. To reset the traction control system
Turn the key to “OFF”. Wait at least 1
second, then turn the key back to
“ON”. The “TCS” indicator/warning
light should go off and the system will
be enabled. The engine trouble warn-
ing light should go off after the motor-
cycle reaches at least 20 km/h (12
mi/h). If the “TCS” indicator/warning
light and/or engine trouble warning
light still remain on after resetting, the
motorcycle may still be ridden; howev-
er, have a Yamaha dealer check the
motorcycle as soon as possible.

TIPThe fuel tank cap cannot be closed un-
less the key is in the lock. In addition,
the key cannot be removed if the cap is
not properly closed and locked.
WARNING
EWA11092
Make sure that the fuel tank cap is
properly closed after fillin g fuel.
Leakin g fuel is a fire hazar d.
EAU13222
FuelMake sure there is sufficient gasoline in
the tank.
WARNING
EWA10882
Gasoline an d 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

Gasoline is poisonous an d can cau-
se injury or death. Han dle gasoline
with care. Never siphon gasoline by
mouth. If you shoul d swallow some

EAU58110
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.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.

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.
