3 decreases. When the fuel level be-
comes low, the last segment will flash,
(“LOW FUEL” message will also ap-
pear) and the fuel level warning
light “ ” will come on. Refuel as soon
as possible.
TIPThis fuel meter is equipped with a self-
diagnosis system. If a problem is de-
tected in the fuel meter electrical cir-
cuit, the display segments of the fuel
meter will flash eight times, and then
go off for 3 seconds repeatedly. If this
occurs, have a Yamaha dealer check
the electrical circuit.
Coolant temperature meter
With the key in the “ON” position, the
coolant temperature meter indicates
the temperature of the coolant. The
coolant temperature varies with
changes in the weather and engine
load. When the coolant temperature is
near the maximum limit, the second
segment from the top will flash. If the 2
top segments and “ ” start flashing
(“HIGH TEMP” message will also ap-
pear), stop the vehicle and let the en-
gine cool.
NOTICE

Do not continue to operate the en-
gine if it is overheating.TIPFor radiator-fan-equipped vehi-

mode and the various tripmeter modes
in the following order:
ODO (odometer) → TRIP 1 (tripmeter)

When approximately 3.0 L (0.79 US
gal, 0.66 Imp.gal) of fuel remains in the
fuel tank, the display will automaticallychange to the fuel reserve tripmeter
mode “F TRIP” and start counting the
distance traveled from that point. In
that case, pushing the “SELECT” but-
ton switches the display between the
various tripmeter and odometer modes
in the following order:
ODO → TRIP 1 → TRIP 2 → F TRIP (fu-

3 Oil change indicator “OIL”
This indicator flashes (message “OIL
SERV” will also appear) to indicate that
the engine oil should be changed. It will
come on at the initial 1000 km (600 mi)
service interval, 2000 km (1200 mi) af-

fore the set oil service interval has been
reached), the indicator must be reset
for the next oil change to be indicated
at the correct time. To reset the oil
change indicator before the periodic oil
change interval has been reached, fol-
low the below procedure.
To reset the oil change indicator (mode
“ODO” should be selected), select
“DIST SERV” by pushing the “INFO”
button, and then push the “RESET”
button for two seconds until “DIST
SERV” mode flashes and then push
and hold the “RESET” button for at
least 15 seconds, “OIL SERV” mes-
sage will also be reset.

The warning message function works
in conjunction with fuel meter, coolant
temperature meter, oil change indica-
tor, and low battery indicator by dis-
playing a corresponding warning
message. When two or more warning
messages occur, display shall be
changed as follows:

Self-diagnosis device
This model is equipped with a self-di-
agnosis device for various electrical
circuits.
If a problem is detected in any of those
circuits, the engine trouble warning
light will come on and the display will
indicate an error code.
If the display indicates any error codes,
note the code number, and then have
a Yamaha dealer check the vehicle.NOTICE
ECA11591
If the display indicates an error
code, the vehicle should be checked
as soon as possible in order to avoid
engine damage.

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.
