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 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 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 “INFO” switch to change the
information display to the traction con-
trol system display. Then push the “IN-
FO” switch for three seconds. The
display will show “TCSOFF” , and the
“TCS” 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 7-20.) Usin g different sized
tires will prevent the traction control
system from controllin g tire rotation
accurately.
Resettin g 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, and possi-
bly the “ ” warning light, too.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, 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 “ ” indicator light should turn off and the system be en-
abled.TIPIf the “ ” 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 thevehicle and turn off the “ ”
warning light.

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 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. 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

some gasoline or inhale a lot of gas-
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.
