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.

D-mo de ( drive mo de)D-mode is an electronically controlled
engine performance system with two
mode selections (touring mode “T” and
sports mode “S”).
WARNING

Do not chan ge the d rive mo de while
the vehicle is movin g.With the throttle grip closed, push the
drive mode switch “MODE” to switch
between modes “S” (sports) and “T”
(touring).
TIP The current drive mode is shown
in the drive mode display (page
5-7).
 The current drive mode is saved
when the vehicle is turned off.
 D-mode cannot be changed while
cruise control is activated.Tourin g mo de “T”
The touring mode “T” is suitable for
various riding conditions.
This mode allows the rider to enjoy
smooth drivability from the low-speed
range to the high-speed range.
Sports mo de “S”
This mode offers a sportier engine re-
sponse in the low- to mid-speed range
compared to the touring mode.

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-

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.

Anti-lock brake system (ABS)This model’s ABS features a dual elec-
tronic control system, which acts on
the front and rear brakes independent-
ly.
Operate the brakes with ABS as you
would conventional brakes. If the ABS
is activated, a pulsating sensation may
be felt at the brake levers. In this situa-
tion, continue to apply the brakes and
let the ABS work; do not “pump” the
brakes as this will reduce braking ef-
fectiveness.
WARNING
EWA16051
Always keep a sufficient d istance
from the vehicle ahea d 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.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 is
turned on and travels at a speed of
10 km/h (6 mi/h) or higher. During
this test, a clicking noise can be
heard and if either brake lever is
even slightly applied, a vibration
can be felt at the lever, but this
does not indicate a malfunction.
 This ABS has a test mode which
allows the owner to experience
the pulsation at the brake levers
when the ABS is operating. How-
ever, special tools are required, so
please consult your Yamaha deal-
er.NOTICE

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. 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.

Your Yamaha engine was designed to
use unleaded gasoline with a research
octane number of 95 or higher. If en-
gine knocking or pinging occurs, use a
gasoline of a different brand or higher
octane rating.
TIP This mark identifies the recom-

specified by European regulation
(EN228).
 Confirm the gasoline pump nozzle
has the same fuel identification
mark.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.
