This warning light flashes or stays on if
an electrical circuit monitoring the en-
gine is not working correctly. If this oc-
curs, have a Yamaha dealer check the
self-diagnosis system.
The electrical circuit of the warning
light can be checked by turning the key
to “ON”. The warning light should
come on for a few seconds, and then
go off.
If the warning light does not come on
initially when the key is turned to “ON”,
or if the warning light remains on, have
a Yamaha dealer check the electrical
circuit.

3 The ABS may not work correctly. If any
of the above occurs, have a Yamaha
dealer check the system as soon as
possible. (See page 3-15 for an expla-
nation of the ABS.)
WARNING
EWA16041
If the ABS warning light does not go
off after traveling at a speed of 10
km/h (6 mi/h) or higher, or if the
warning light comes on or flashes
while riding, the brake system re-
verts to conventional braking. If ei-
ther of the above occurs, or if the
warning light does not come on at
all, use extra caution to avoid possi-
ble wheel lock during emergency
braking. Have a Yamaha dealer
check the brake system and electri-
cal circuits as soon as possible.
EAUM3440Tachometer high-rpm warning light
This light flashes at 9500 r/min to warn
you that the engine speed is about to
enter the high-rpm zone. Once the en-
gine speed reaches 10000 r/min, this
light will come on to warn you that it is
necessary to shift up to avoid engine
damage.
To activate or deactivate the tachome-
ter high-rpm warning light, hold the
“INFO” button pushed, turn the key to
“ON”, and when the tachometer high-
rpm warning light starts flashing, press
the “SELECT” button.
TIP
When activating or deactivating the
warning light the function, after press-
come on to indicate that the function is
activated or the light will go off to indi-
cate that the function is deactivated.

Multi-function meter unit
WARNING
EWA12423
Be sure to stop the vehicle before
making any setting changes to the
multi-function meter unit. Changing
settings while riding can distract the
operator and increase the risk of an
accident.
The multi-function meter unit is
equipped with the following:a speedometer
a tachometer
a clock
a fuel meter
a coolant temperature meter
an odometer and tripmeter display
a multi-function display
a self-diagnosis device
TIP
B e s u r e t o t u r n t h e k e y t o “ O N ” b e -
fore using the “SELECT”, “RE-
SET” and “INFO” buttons.
When the key is turned to “ON”, all
display segments of the multi-
function meter unit will momen-
tarily appear in order to test the
electrical circuit. The speedome-
ter, tachometer, fuel meter and
coolant temperature meter will
then perform a display check and
a welcome message will scroll
across the multi-function display.
For the U.K. only: To switch the
speedometer and multi-function
displays between kilometers and
miles, press the “SELECT” and
“RESET” button together, turn the
key to “ON” and then release the
buttons. Press the “SELECT” but-
ton to switch between kilometers
and miles and then press the “SE-
LECT” button for two seconds to
confirm the setting.

3 Tachometer
The tachometer allows the rider to
monitor the engine speed and keep it
within the ideal power range.
When the key is turned to “ON”, the ta-
chometer will sweep across the r/min
range and then return to zero r/min in
order to test the electrical circuit.
NOTICE
ECAM1150
Do not operate the engine in the ta-
chometer high-rpm zone.
High-rpm zone: 10000 r/min and
above
Clock
The clock displays when the key is
turned to “ON”. To set the clock
1. Turn the key to “ON”.
2. Push the “SELECT” button for at
least two seconds.
3. When the hour digits start flash-
ing, use the “RESET” button to set
the hours.
4. Push the “SELECT” button , and
the minute digits will start flashing.
5. Use the “RESET” button to set the
minutes.
6. Push the “SELECT” button and
then release it to start the clock.
TIP
When setting the hours and minutes,

crease the increment value one by one,
or push and hold the button to increase
the increment value continuously.
Fuel meter
The fuel meter indicates the amount of
fuel in the fuel tank. The display seg-
ments of the fuel meter disappear to-
wards “E” (Empty) as the fuel level
decreases. When the fuel level be-
comes low, the last segment will flash,

EAU60021
ABS (for ABS models)
The Yamaha ABS (Anti-lock Brake
System) features a dual electronic con-
trol system, which acts on the front and
rear brakes independently.
Operate the brakes with ABS as you
would conventional brakes. If the ABS
is activated, a pulsating sensation may
be felt at the brake lever or brake ped-
al. In this situation, continue to apply
the brakes and let the ABS work; do
not “pump” the brakes as this will re-
duce braking effectiveness.
WARNING
EWA16051
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
hydraulic control unit, and if the
brake lever or brake pedal is even
slightly applied, a vibration can be
felt at the lever and pedal, but
these do not indicate a malfunc-
tion.This ABS has a test mode which
allows the owner to experience
the pulsation at the brake lever or
brake pedal when the ABS is op-
erating. However, special tools are
required, so please consult your
Yamaha dealer.
NOTICE
ECA20100
Be careful not to damage the wheel
sensor or wheel sensor rotor; other-
wise, improper performance of the
ABS will result.
1. Front wheel sensor rotor
2. Front wheel sensor
1. Rear wheel sensor rotor
2. Rear wheel sensor
