been set.
Automatic deactivation of the cruisecontrol systemThe cruise control system is electroni-
cally controlled and linked with other
control systems. The cruise control
system will automatically deactivate
under the following conditions:  The cruise control system is not
able to maintain the set cruising
speed (such as when going up a
steep hill).
 Wheel slip or wheel spin is detect-
ed. (If the traction control system
is on, traction control will engage.)
 Engine trouble, etc.
If the cruise control system is automat-
ically deactivated, the “ ” indicator
light will turn off and the “ ” indica-
tor light will flash for 4 seconds.
If the cruise control system was auto-
matically deactivated, please stop and
confirm that your vehicle is in good op-
erating condition before continuing on.
When traveling on roads with steep
grades, the cruise control system may
not be able to maintain the set cruising
speed.

When going uphill, the actual trav-
eling speed may become lower
than the set cruising speed. If this
occurs, accelerate to the desired
traveling speed using the throttle.
 When going downhill, the actual
traveling speed may become
higher than the set cruising speed.
If this occurs, the setting switch
cannot be used to adjust the set
cruising speed. To reduce the
traveling speed, apply the brakes.
When the brakes are applied, the
cruise control system will deacti-
vate.

EAU88851
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 as needed until traction
is restored.
When traction control has engaged,
the “ ” indicator light will flash. You
may notice changes in engine re-
sponse or exhaust sounds.
WARNING
EWA18860
The traction control system is not a
substitute 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,
see page 5-11.TIP Turn the traction control system
off to help free the rear wheel if the
vehicle gets stuck in mud, sand, or
other soft surfaces.
 When the vehicle is on the center-
stand, do not rev the engine for an
extended period of time. Other-
wise, the traction control system
will automatically disable and
need to be reset.
NOTICE
ECA16801
Use only the specifie d tires. (See
pa ge 8-19.) Usin g different size d
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.
If the traction control system automat-
ically disables, reset it by riding under
normal conditions.TIPIf the Ž indicator light remains on,
the vehicle may still be ridden; howev-
er, have a Yamaha dealer check the
vehicle as soon as possible.

Malfunction in dicator li ght
(MIL) “ ”
This light comes on or flashes if a prob-
lem is detected in the engine or other
vehicle control system. If this occurs,
have a Yamaha dealer check the on-
board diagnostic system. The electri-
cal circuit of the warning light can be
checked by vehicle power on. The light
should come on for a few seconds,
and then go off. If the light does not
come on initially when the vehicle pow-
er on, or if the light remains on, have a
Yamaha dealer check the vehicle.
NOTICE

If the MIL starts flashin g, re duce en-
g ine spee d to prevent exhaust sys-
tem damag e.TIPThe engine is sensitively controlled for
the on-board diagnostic system to de-
tect deterioration and malfunction of
the emission control system. Due to
this specification, the MIL may come
on or flash for vehicle modifications,
lack of maintenance, or excessive or
improper use of the vehicle. To prevent
this, observe these precautions.
 Do not attempt to modify the soft-
ware of the engine control unit.
 Do not add any electrical acces-
sories that interfere with engine
control.
 Do not use aftermarket accesso-
ries or parts such as suspension,
spark plugs, injectors, exhaust
system, etc.
 Do not change drivetrain specifi-
cations (chain, sprockets, wheels,
tires, etc.). 
Do not remove or alter the O2 sen-
sor, air induction system, or ex-
haust parts (catalysts or EXUP,
etc.).
 Maintain proper V-belt and drive
belt (if equipped).
 Maintain correct tire pressure.
 Do not operate the vehicle in an
extreme manner. For example, re-
peated or excessive opening and
closing of the throttle, racing,
burnouts, wheelies, etc.
