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.

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

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.

BC
The brake control system has two set-
tings, BC1 and BC2. Select BC1 when
only standard ABS is desired. Select
BC2 to have the brake control system
further regulate brake pressure while
cornering to suppress lateral wheel
slip.TIPFor skilled riders and when riding at the
track, due to varying conditions, the
BC2 brake system may engage sooner
than expected relative to your desired
cornering speed or intended cornering
line.
QSThe quick shift system indicators are
divided into QS and QS sections.
QS and QS are not linked and
can be independently turned on or off.
QS can be set to ON or OFF.
OFF turns the respective upshift or
downshift function off, and the clutch
lever must then be used when shifting
in that direction.TIPIf the QSS setting cannot be changed:
turn the engine off with the gear posi-
tion set to neutral, then change the set-
ting.
“Shift In
dicator”
This module allows a custom shift indi-
cator to be set. When the engine r/min
(rotations per minute) are in the speci-
fied range, the gear indicator will flash.
This module has 3 options:
“IND Mode” - the shift indicator can be
turned ON/OFF
“IND Start” - the r/min at which the in-
dicator starts flashing can be chosen.
Once selected, rotate the wheel switch
up/down to increase or decrease the
r/min value by increments of 200 r/min.
“IND Start” is settable between 6000 -
12800 r/min.
“IND Stop” - the r/min at which the in-
dicator stops flashing can be chosen.
Once selected, rotate the wheel switch
up/down to increase or decrease the
km/h
