Wheel slip or wheel spin is detect-
ed. (If the traction control system
has not been turned off, the trac-
tion control system will work.)
 The start/engine stop switch is set
to the “ ” position.
 The engine stalls.
 The sidestand is lowered.
When traveling with a set cruising
speed, if the cruise control system is
deactivated under the above condi-
tions, the “ ” indicator light will go
off and the “ ” indicator light will
flash for 4 seconds, and then go off.
When not traveling with a set cruising
speed, if the start/engine stop switch is
set to the “ ” position, the engine
stalls, or the sidestand is lowered, then
the “ ” indicator light will go off
(the “ ” indicator light will not flash).
If the cruise control system is automat-
ically deactivated, please stop and
confirm that your vehicle is in good op-
erating condition.
Before using the cruise control system
again, activate it using the power
switch.
TIPIn some cases, the cruise control sys-
tem may not be able to maintain the set
cruising speed when the vehicle is
traveling uphill or downhill.  When the vehicle is traveling up-
hill, the actual traveling speed may
become lower than the set cruis-
ing speed. If this occurs, acceler-
ate to the desired traveling speed
using the throttle.
 When the vehicle is traveling
downhill, the actual traveling
speed may become higher than
the set cruising speed. If this oc-
curs, 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 become deac-
tivated.

“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 4-18.
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 rid ing appropriately
for the con ditions. Traction control
cannot prevent loss of traction d ue
to excessive speed when entering
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.

TIPSet “TCS-MODE” to “OFF” to help free
the rear wheel if the motorcycle gets
stuck in mud, sand, or other soft sur-
faces.NOTICE
ECA16801
Use only the specified tires. (See
pa ge 7-15.) Usin g different sized
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 power is regulated to slow front-wheel
lift while still providing good accelera-
tion.
EAU91340
QSSThe quick shift system allows for clutch
lever-less, electronically-assisted shift-
ing. When the sensor on the shift rod
detects the appropriate motion in the
shift pedal, engine power output is mo-
mentarily adjusted to allow for the gear
change to occur.
QSS does not operate when the clutch
lever is pulled, therefore normal shifting
can be done even when QSS is set to
on. Check the QS indicator for current
status and usability information.

BCThe brake control system regulates hy-
draulic brake pressure for the front and
rear wheels when the brakes are ap-
plied and wheel lock is detected. This
system has two settings.
BC1 is standard ABS, which adjusts
brake pressure based on vehicle
speed and wheel speed data. BC1 is
designed to engage and maximize
braking when the vehicle is upright.
BC2 uses additional data from the IMU
to regulate applied brake power when
cornering to suppress lateral wheel
slip.

“Manual TCS Settin
g”
This module allows you to customize
the “TCS-MODE M” which is accessi-
ble on the main display using the
MODE switches.
TCS
This model uses a variable traction
control system. For each setting level,
the further the vehicle is leaned over,
the greater the amount of traction con-
trol (system intervention) is applied.
There are 3 setting levels available for
the “TCS-MODE M”. Setting level 1 applies the least amount
of overall system intervention, while
setting level 3 applies the greatest
amount of overall traction control.
TIP
TCS can only be turned on or off
via the main display using the
MODE switches.
 SCS and LIF can be turned off in-
dependently of TCS for “TCS-
MODE M”.
 When “TCS-MODE” has been set
to “OFF” on the main display:
TCS, SCS and LIF are all turned
off together.SCSSCS can be set to OFF, 1, 2, and 3.
OFF turns the slide control system off,
setting level 1 provides the least
amount of system intervention, and
setting level 3 provides the greatest
amount of system intervention.
LIFLIF can be set to OFF, 1, 2, and 3. Setting level 1 provides the least
amount of system intervention and set-
ting 3 most strongly reduces the rate of
wheel lift.
OFF turns LIF off.

Brake control system (BC)The brake control system regulates hy-
draulic brake pressure for the front and
rear wheels independently when the
brakes are applied and wheel lock is
detected. This system has two settings
which can be changed in the settings
MENU. (See page 4-18.)
BC1 is standard ABS, which adjusts
brake pressure based on vehicle
speed and wheel speed data. BC1 is
designed to engage and maximize
braking when the vehicle is upright.
BC2 uses additional data from the IMU
to regulate applied brake power when
cornering to suppress lateral wheel
slip.
Regarding ABS, operate the brakes as
you would conventional brakes. When
the brake control system engages, a
pulsating sensation may be felt at the
brake lever or brake pedal as the hy-
draulic unit rapidly applies and reduces
brake pressure. In this situation, conti-
nue to apply the brake lever and brake
pedal to allow the ABS to work—do
not “pump the brakes” as this will re-
duce braking effectiveness.
WARNING
EWA16051
Always keep a sufficient d istance
from the vehicle ahead to match the
ri din g speed even with ABS.
 The ABS performs b est with
lon g b rakin g d istances.
 On certain surfaces, such as
roug h or g ravel roa ds, the b rak-
in g d istance may be lon ger with
the ABS than without.The ABS hydraulic unit is monitored by
the ABS ECU, which will revert the sys-
tem to conventional braking if a mal-
function occurs.
WARNING
EWA20891
The brake control system is not a
su bstitute for the use of proper ri d-
in g an d brakin g techniques. The
b rake control system cannot pre-
vent all loss of traction due to over-
b rakin g from excessive spee d, or
lateral wheel slip when brakin g on
slippery surfaces.
