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
ECA20100
Be careful not to damag e the wheel
sensor or wheel sensor rotor; other-
wise, improper performance of the
ABS will result.

Ig nition circuit cut-off systemThe ignition circuit cut-off system
(comprising the sidestand switch and
brake light switches) has the following
functions.
 It prevents starting when the side-
stand is up, but neither brake is applied.
 It prevents starting when either
brake is applied, but the sidestand
is still down.
 It cuts the running engine when
the sidestand is moved down.
Periodically check the operation of the
ignition circuit cut-off system accord-
ing to the following procedure.

Startin g the eng ineThe ignition circuit cut-off system will
enable starting when the sidestand is
up.
To start the engine1. With the smart key turned on, ap-
proach the vehicle.
2. Push the “ON/ ” switch and set the engine stop switch to the run
position.
Upon authentication of the smart
key, the beeper will sound twice
and the centerstand and steering
locks (if applied) will be released.
3. Confirm the indicator and warning light(s) come on for a few sec-
onds, and the go off. (See page
5-2.)TIPDo not start the engine if the mal-
function indicator light remains on.
 The ABS warning light should
come on and stay on until the ve-
hicle reaches a speed of 10 km/h
(6 mi/h).

TIPThis model is equipped with:
 a lean angle sensor. This sensor
stops the engine in case of a vehi-
cle turnover. If this happens, the
malfunction indicator light will
come on, but this is not a malfunc-
tion. Turn the vehicle power off
and then back on again to cancel
the indicator light. Failing to do so
will prevent the engine from start-
ing even though the engine will
crank when pushing the start
switch.
 an engine auto-stop system. The
engine stops automatically if left
idling for 20 minutes. If the engine
stops, simply push the start
switch to restart the engine.

Periodic inspection, adjustment, and
lubrication will keep your vehicle in the
safest and most efficient condition
possible. Safety is an obligation of the
vehicle owner/operator. The most im-
portant points of vehicle inspection,
adjustment, and lubrication are ex-
plained on the following pages.
The intervals given in the periodic
maintenance charts should be simply
considered as a general guide under
normal riding conditions. However, de-
pending on the weather, terrain, geo-
graphical location, and individual use,
the maintenance intervals may need to
be shortened.
WARNING
EWA10322
Failure to properly maintain the vehi-
cle or performin g maintenance ac-
tivities incorrectly may increase
your risk of injury or death durin g
service or while usin g the vehicle. If
you are not familiar with vehicle ser-
vice, have a Yamaha d ealer perform
service.

EAU17303
Emission controls not only function to
ensure cleaner air, but are also vital to
proper engine operation and maximum
performance. In the following periodic
maintenance charts, the services relat-
ed to emissions control are grouped
separately. These services require
specialized data, knowledge, and
equipment. Maintenance, replace-
ment, or repair of the emission control
devices and systems may be per-
formed by any repair establishment or
individual that is certified (if applicable).
Yamaha dealers are trained and equipped to perform these particular
services.

TIPAir filters
 The engine air filter uses a disposable oil-coated paper el ement. This element cannot be cleaned with compressed air,
doing so will only damage it.
 If you often ride in the rain or in dusty areas, have the engine air filter and V-belt air filter elements serviced more fre-
quently.
Hydraulic brake service  Regularly check the brake fluid levels in the reservoirs, and refill as necessary.
 Replace the internal components of the brake master cylinders and calipers, and change the brake fluid every 2 years.
 Replace the brake hoses every 4 years, or sooner if cracked or damaged.30 *Throttle g
