Oil pressure and coolant tempera-
ture warning light
This warning light comes on if the en-
gine oil pressure is low or if the coolant
temperature is high. If this occurs, stop
the engine immediately.
The electrical circuit of the warning light
can be checked by turning the key to
“ON”. The warning light should come
on again after going off briefly, and then
remain on until the engine is started. If
the warning light does not come on ini-
tially when the key is turned to “ON”,
have a Yamaha dealer check the elec-
trical circuit.NOTICE

cle and engine immediately.
If the engine is overheating, the
coolant temperature warning
icon will come on. Let the en-
gine cool. Check the coolant
level (see page 7-38).

If the engine oil pressure is low, the oil pressure warning icon
will come on. Check the oil level
(see page 7-12).

If the warning light remains on
after letting the engine cool and
confirming the proper oil level,
have a Yamaha dealer check the

Oil pressure warning “ ”
This icon, along with the oil pressure
and coolant warning light, comes on
when the engine oil pressure is low.
When the key is first turned to ON, en-
gine oil pressure has yet to build, so this
icon will come on and stay on until the
engine has been started.
NOTICE
ECA21210
If the warning light comes on when
the engine is running, stop the en-
gine immediately and check oil level.
If the oil level is below the minimum level, add sufficient oil of the recom-
mended type to raise it up to the cor-
rect level. If the oil pressure warning
light remains on even if the oil level
is correct, immediately turn the en-
gine off and have a Yamaha dealer
check the vehicle.
Coolant temperature warning “ ”
This icon comes on if the coolant tem-
perature reaches 117
C (242 F) or
higher. Stop the vehicle and turn off the
engine. Allow the engine to cool.NOTICE

Tips for reducing fuel
consumptionFuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:
Shift up swiftly, and avoid high en-
gine speeds during acceleration.

Do not rev the engine while shifting
down, and avoid high engine
speeds with no load on the engine.

Turn the engine off instead of let-
ting it idle for an extended length of
time (e.g., in traffic jams, at traffic
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 follow-
ing 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.
EAU17085
0–1000 km (0–600 mi)
Avoid prolonged operation above 7000
r/min. NOTICE: After 1000 km (600
mi) of operation, the engine oil must
be changed and the oil filter car-
tridge or element replaced.
[ECA10303]
1000–1600 km (600–1000 mi)
Avoid prolonged operation above 8400 r/min.
1600 km (1000 mi) and beyond
The vehicle can now be operated nor-
mally.
NOTICE
ECA10311

Keep the engine speed out of
the tachometer red zone.

If any engine trouble should oc-
cur during the engine break-in
period, immediately have a
Yamaha dealer check the vehi-cle.
TIPDuring and after the engine break-in
period, the exhaust heat may cause
discoloration of the exhaust pipe, butthis is normal.

Engine overheating
WARNING
EWAT1041

Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.

Place a thick rag, like a towel, over the radiator cap, and then slowly rotate the cap counterclockwise to the de-
tent to allow any residual pressure to escape. When the hissing sound has stopped, press down on the capwhile turning it counterclockwise, and then remove the cap.
TIPIf coolant is not available, tap water can be temporarily
used instead, provided that it is changed to the recommended coolantas 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.)
Start the engine. If the engine overheats again,
have a
Yamaha dealer check
and repair the cooling system.
There is
leakage.
There is
no leakage.
