INSTRUMENT AND CONTROL FUNCTIONS
TIP
As the unified brake system is me-
chanical, additional free play can
be felt in the front brake lever
when the rear brake lever is being
3
pulled.
The unified brake system does not
function when the front brake is
applied alone.
ABS
Your leaning multi-wheel vehicle's ABS
(Anti-lock Brake System) features an
electronic control system, which acts
on each of the front and rear brakes in-
dependently.
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
Always keep a sufficient distance
from the vehicle ahead to match the
riding speed even with ABS.
The ABS performs best with
long braking distances.
On certain surfaces, such as
rough or gravel roads, the brak-
ing distance may be 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 first
starts off after the key is turned to
"ON" and the vehicle has traveled
at a speed of 10 km/h (6 mi/h) or
higher. During this test, a "click-
ing" noise can be heard from the
front of the vehicle, and if either
brake lever is even slightly ap-
plied, a vibration can be felt at the
lever, but these do not indicate a
malfunction.
This ABS has a test mode which
allows the owner to experience
EWA16051
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
Be careful not to damage the wheel
sensor or wheel sensor rotor; other-
wise, improper performance of the
ABS will result.
