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.

TIPThis model is equipped with:  a lean angle sensor to stop the en-
gine in case of a turnover. In this
case, the display will indicate error
code 30, but this is not a malfunc-
tion. Turn the key to “OFF” and
then to “ON” to clear the error
code. Failing to do so will prevent
the engine from starting even
though the engine will crank when
pushing the start switch.
 an engine auto-stop system. The
engine stops automatically if left
idling for 20 minutes. In this case,
the display will indicate error code
70, but this is not a malfunction.
Push the start switch to clear the
error code and to restart the en-
gine.
EAU51792
Startin g the en gineIn order for the ignition circuit cut-off
system to enable starting, one of the
following conditions must be met:
 The transmission is in the neutral
position.
 The transmission is in gear with
the clutch lever pulled and the
sidestand up.
See page 3-22 for more informa-
tion.
1. Turn the key to “ON” and make sure that the engine stop switch is
set to “ ”.
The following warning lights and
indicator light should come on for
a few seconds, then go off. Oil level warning light
 Coolant temperature warning
light
 Engine trouble warning light
 Immobilizer system indicator

610. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.
TIPAfter the engine is started, the engine
oil level warning light should go off if
the oil level is sufficient.NOTICE
ECA10402
If the oil level warnin g lig ht flickers
or remains on even if the oil level is
correct, imme diately turn the en gine
off an d have a Yamaha d ealer check
the vehicle.11. Turn the engine off, wait a few minutes until the oil settles, and
then check the oil level and cor-
rect it if necessary.
12. Install the cowling.
EAU20071
CoolantThe coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU46804
To check the coolant level 1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion.TIPThe coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
 Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.2. Check the coolant level in the
coolant reservoir.TIPThe coolant should be between the
minimum and maximum level marks.
3. If the coolant is at or below theminimum level mark, remove the
coolant reservoir breather hose
from the guide, and then remove
the coolant reservoir cap.
WARNING! Remove only the
coolant reservoir cap. Never at-
tempt to remove the ra diator
cap when the en gine is hot.
