This indicator light flashes when the
turn signal switch is pushed to the left
or right.
EAU11061
Neutral in dicator li ght “ ”
This indicator light comes on when the
transmission is in the neutral position.

This indicator light comes on when the
high beam of the headlight is switched
on.
EAU11255
Oil level warnin g lig ht “ ”
This warning light comes on if the en-
gine oil level is low.
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.
TIP Even if the oil level is sufficient, the
warning light may flicker when rid-
ing on a slope or during sudden
acceleration or deceleration, but
this is not a malfunction.
 This model is also equipped with a
self-diagnosis device for the oil
level detection circuit. If a problem
is detected in the oil level detec-
tion circuit, the following cycle will
be repeated until the malfunction
is corrected: The oil level warning
light will flash ten times, then go
off for 2.5 seconds. If this occurs,
have a Yamaha dealer check the
vehicle.
EAU1142D
Coolant temperature warnin g

This warning light comes on if the en-
gine overheats. If this occurs, reduce
the load on the engine immediately. If
message “HI” flashes in the coolant
temperature display, stop the vehicle,
then stop the engine and let the engine
cool.

ine if it is overheatin g.TIP For radiator-fan-equipped vehi-
cles, the radiator fan(s) automati-
cally switch on or off according to
the coolant temperature in the ra-
diator.
 If the engine overheats, see page

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 last segment on
the left starts flashing, refuel as soon as
possible.
TIPThis fuel meter is equipped with a self-
diagnosis system. If a problem is de-
tected in the electrical circuit, the fol-
lowing cycle is repeated until the
malfunction is corrected: fuel level seg-
ments and symbol “ ” flash eight times, then go off for approximately 3
seconds. If this occurs, have a Yamaha
dealer check the electrical circuit.
Coolant temperature

The coolant temperature display indi-
cates the temperature of the coolant.NOTICE

Self-d iagnosis 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.
The self-diagnosis device also detects
problems in the immobilizer system
circuits.

Tips for re ducin g fuel con-
sumptionFuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:
 Shift up swiftly, and avoid high en-
gine speeds during acceleration.
 Do not rev the engine while shift-
ing down, and avoid high engine
speeds with no load on the en-
gine.
 Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at traf-
fic lights or at railroad crossings).
EAU16842
Engine break-inThere is never a more important period
in the life of your engine than the period
between 0 and 1600 km (1000 mi). For
this reason, you should read the fol-
lowing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that
might result in engine overheating
must be avoided.
EAU17094
0–1000 km (0–600 mi)
Avoid prolonged operation above 5800
r/min. NOTICE: After 1000 km (600
mi) of operation, the en gine oil must
b e chan ged an d the oil filter car-
tri dge or element replace d.
[ECA10303]
1000–1600 km (600–1000 mi)
Avoid prolonged operation above 6900
r/min.

Do not remove the ra diator cap when the en gine an d ra diator are hot. Scal din g hot flui d an d steam may be
b lown out un der pressure, which coul d cause serious injury. Be sure to wait until the en gine has coole d.
 After removin g the ra diator cap retainin g b olt, place a thick ra g, like a towel, over the rad iator cap, and then
slowly rotate the cap counterclockwise to the d etent to allow any residual pressure to escape. When the hiss-
in g soun d has stoppe d, press d own on the cap while turnin g it counterclockwise, an d then remove the cap.TIPIf coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended cool-
ant as soon as possible.
Wait until the
engine has cooled.
Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer checkand repair the cooling system.Add coolant. (See TIP.)
