“D-MODE”“D-MODE” is an electronically con-
trolled engine performance system.
WARNING
EWA18440
Do not change the d rive mo de while
the vehicle is movin g.The “D-MODE” system consists of 4
different control maps which regulate
engine response and output, thus pro-
viding you with a selection of modes to
fit your preferences and the riding envi-
ronment.
D-MODE 1 - Sporty engine response
D-MODE 2 - Moderate engine re-
sponse
D-MODE 3 - Mild engine response
D-MODE 4 - Mild engine response and
limits engine outputTIP The current “D-MODE” setting is
shown in the MODE display. (See
page 4-11.)
 The current “D-MODE” setting is
saved when the vehicle is turned
off. 
The “D-MODE” is controlled by
the MODE switches, see page 4-4
for more information.
EAU91432
“TCS-MODE”This model is equipped with adjustable
traction, slide, and lift control systems
(TCS, SCS and LIF). These are
grouped together into “TCS-MODE”.
“TCS-MODE” has 4 settings:
“TCS-MODE M” is customizable in the
settings MENU, see page 4-15.
TCS
The traction control system helps
maintain traction when accelerating. If
sensors detect that the rear wheel is
starting to slip (uncontrolled spinning),
the traction control system assists by
regulating engine power as needed un-
til traction is restored. The stability
control indicator light “ ” flashes to
let the rider know that traction control
has engaged.

This traction control system automati-
cally adjusts according to the vehicle’s
lean angle. To maximize acceleration,
when the vehicle is upright a lesser
amount of traction control is applied.
When cornering, a greater amount of
traction control is applied.
TIP
The traction control system may
engage when the vehicle travels
over a bump.
 You may notice slight changes in
engine and exhaust sounds when
the traction control or other sys-
tems engage.
 The traction control system can
only be turned off by setting “TCS-
MODE” to “OFF”, using the MODE switches. See page 4-4 for more
information on “TCS-MODE”.
 When “TCS-MODE” has been set
to “OFF”, the TCS, SCS and LIF
systems are all turned off togeth-
er.
WARNING
EWA15433
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 brakin g,
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.When the vehicle power is on, the trac-
tion 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.
TIP
the rear wheel if the motorcycle gets
stuck in mud, sand, or other soft sur-
faces.NOTICE
ECA16801
Use only the specifie d tires. (See
pa ge 7-15.) Usin g different size d
tires will prevent the traction control
system from controllin g tire rotation
accurately.SCS
The slide control system regulates en-
gine power output when a sideward
slide is detected in the rear wheel. It
adjusts power output based on data
from the IMU (Inertial Measurement
Unit). This system supports the TCS to
contribute to a smoother ride.
LIF
The lift control system reduces the rate
at which the front wheel rises during
extreme acceleration, such as during
starts or out-of-corner exits. When
front-wheel lift is detected, engine

registering key (red bow), keep it in a
safe place and only use it for code re-
registering.

Fuel level warning light “ ”
This warning light comes on when the
fuel level drops below approximately
2.8 L (0.74 US gal, 0.62 Imp.gal). When
this occurs, refuel as soon as possible.
The electrical circuit of the warning
light can be checked by turning the ve-
hicle on. The warning light should
come on for a few seconds, and then
go off.
TIPIf the warning light does not come on at
all, remains on after refueling, or if the
warning light flashes repeatedly, have
a Yamaha dealer check the vehicle.
EAU88331
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 turning the 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 ve-
hicle power is turned on, or if the light
remains on, have a Yamaha dealer
check the vehicle.NOTICE
ECA26820
If the MIL starts flashin g, re duce en-
g ine spee d to prevent exhaust sys-
tem damag e.
TIPThe engine is sensitively monitored by
the on-board diagnostic system to de-
tect deterioration or malfunction of the
emission control system. Therefore the
MIL may come on or flash due to vehi-
cle modifications, lack of maintenance,
or excessive/improper use of the mo-
torcycle. 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 the drivetrain
specifications (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 the drive chain properly.
 Maintain correct tire pressure.

Maintain proper brake pedal
height to prevent rear brake from
dragging.
 Do not operate the vehicle in an
extreme manner. For example, re-
peated or excessive opening and
closing of the throttle, racing,
burnouts, wheelies, extended
half-clutch use, etc.

ABS warnin g li ght “ ”
In normal operation, the ABS warning
light comes on when the vehicle is
turned on, and goes off after traveling
at a speed of 5 km/h (3 mi/h) or higher.TIPIf the warning light does not work as
described above, or if the warning light
comes on while riding, the ABS may
not work correctly. Have a Yamaha
dealer check the vehicle as soon as
possible.
WARNING
EWA21120
If the ABS warnin g lig ht does not
turn off after reachin g 5 km/h (3
mi/h), or if the warnin g li ght comes
on while ri din g:

Immo bilizer system in dicator
li g ht “ ”
When the main switch is turned off and
30 seconds have passed, the indicator
light will flash steadily to indicate the
immobilizer system is enabled. After 24
hours have passed, the indicator light
will stop flashing, however the immobi-
lizer system is still enabled.TIPWhen the vehicle is turned on, this light
should come on for a few seconds and
then go off. If the light does not come
on, or if the light remains on, have a
Yamaha dealer check the vehicle.
Transpon der interference
If the immobilizer system indicator light
flashes in the pattern, slowly 5 times
then quickly 2 times, this could be
caused by transponder interference. If
this occurs, try the following. 1. Make sure there are no other im- mobilizer keys close to the main
switch.
2. Use the code re-registering key to start the engine.
3. If the engine starts, turn it off, and try starting the engine with the
standard keys.
4. If one or both of the standard keys do not start the engine, take the
vehicle and all 3 keys to a Yamaha
dealer to have the standard keys
re-registered.
