TCS, SCS, or LIF systems have en-
gaged. It will also come on if the TCS is
set to “OFF” or if the TCS system be-
comes disabled while riding.
The electrical circuit of the light can be
checked by turning the key to “ON”.
The light should come on for a few sec-
onds and then go off. If the light does
not come on initially when the key is
turned to “ON”, or if the light remains
on, have a Yamaha dealer check the
vehicle.
EAU78410
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
ECA22441
If the oil pressure and coolant warn-
ing light does not go off after start-
ing the engine or if it comes on while
the engine is running, stop the vehi-
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 7-40).

If the engine oil pressure is low,
the oil pressure warning icon
will come on. Check the oil level
(see page 7-13).

If the warning light remains on
after letting the engine cool and
confirming the proper oil level,
have a Yamaha dealer check the
vehicle. Do not continue to op-erate the vehicle!

warning light “ ”
This warning light comes on if a prob-
lem is detected in the electronic sus-
pension or steering damper.

Warning icons
When an error is detected, the following
error-related warning icons will then be
viewable.

SCU trouble warning icon

Steering damper warning icon

Coolant temperature warning icon

Oil pressure warning icon
SCU trouble warning “ ”
(YZF-R1M)
The SCU trouble warning icon appears
if a problem is detected in the front or
rear suspension. Steering damper warning “ ”
The steering damper warning icon ap-
pears if a problem is detected in the
steering damper.
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
ECA10022
Do not continue to operate the en-gine if it is overheating.
Oil pressure warning “ ”
This icon comes on when the engine oil
pressure is low. When the key is first
turned to ON, engine 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.
Error mode warning “Err”
When an internal error occurs (e.g.,
communication with a system controller
has been cut off), the error mode warn-
ing will appear as follows.
“Err” and “ ” indicates an ECU error.
“Err” and “ ” indicates an SCU error.
“Err” only indicates an HCU (hydraulic
control unit) error.TIP
Depending on the nature of the er-
ror, the display may not function
properly and YRC settings may be
impossible to change. Additionally,
ABS and UBS may not function
properly. Use extra care when
braking and have a Yamaha deal-er check the vehicle immediately.

the neutral position, do not
coast for long periods of time
with the engine off, and do not
tow the motorcycle for long dis-
tances. The transmission is
properly lubricated only when
the engine is running. Inade-
quate lubrication may damage
the transmission.

Except when upshifting with the
QSS turned on, always use the
clutch while changing gears to
avoid damaging the engine,
transmission, and drive train,
which are not designed to with-
stand the shock of forced shift-ing.
EAU16811
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


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 us
ed 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.
