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.
EAU11367
Fuel level warnin g li ght “ ”
This warning light comes on when the
fuel level drops below approximately
3.5 L (0.92 US gal, 0.77 Imp.gal). When
this occurs, refuel as soon as possible.
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.

TIPThis model is also equipped with a self-
diagnosis device for the fuel level de-
tection circuit. If a problem is detected
in the fuel level detection circuit, the
following cycle will be repeated until
the malfunction is corrected: The fuel
level warning light will flash eight times,
and then go off for 3.0 seconds. If this
occurs, have a Yamaha dealer check

li g ht “ ”
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. 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

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

 a speedometer
 a tachometer
 an odometer
 two tripmeters (which show the
distance traveled since they were
last set to zero)
 a fuel reserve tripmeter (which
shows the distance traveled since
the fuel level warning light came
on)
 a stopwatch
 a clock
 a coolant temperature display
 an air intake temperature display
 a self-diagnosis device
 a display brightness and shift tim-
ing indicator light control modeTIPBe sure to turn the key to “ON” be-

the coolant temperature is auto-
matically displayed, even if the air
intake temperature was displayed

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 right display
will indicate an error code.
If the right 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.
If a problem is detected in the immobi-
lizer system circuits, the immobilizer
system indicator light will flash and the
right display will indicate an error code.
TIPIf the right display indicates error code
52, this could be caused by transpon-
der interference. If this error code ap-
pears, try the following.1. Use the code re-registering key to
start the engine.TIPMake sure there are no other immobi-
lizer keys close to the main switch, and
do not keep more than one immobilizer
key on the same key ring! Immobilizer system keys may cause signal interfer-
ence, which may prevent the engine
from starting.
2. If the engine starts, turn it off and
try starting the engine with the
standard keys.
3. If one or both of the standard keys do not start the engine, take the
vehicle, the code re-registering
key and both standard keys to a
Yamaha dealer and have the stan-
dard keys re-registered.NOTICE
