4 When the vehicle is turned on, the light
will perform a circuit check (come on
for a few seconds and then go off).
If the warning light remains on after
confirming that the oil level is correct
(page 7-13), have a Yamaha dealer
check the vehicle.
TIP

Even if the oil level is sufficient, the
warning light may flicker when rid-
ing up or downhill, or during sud-
den acceleration or deceleration,
but this is not a malfunction.
 If a malfunction is detected, the oil
level warning light will flash re-
peatedly. Have a Yamaha dealer
check the vehicle.
EAU11369Fuel level warnin g lig ht “ ”
This warning light comes on when you
are low on fuel. When the fuel level
drops below approximately 3.4 L (0.90
US gal, 0.75 Imp.gal), the light will
come on to remind you to refuel as
soon as possible.
When the vehicle is turned on, the light
will perform a circuit check (come on
for a few seconds and then go off).
If the warning light does not come on
during the circuit check, or if the warn-
ing light remains on after refueling,
have a Yamaha dealer check the vehi-
cle.
TIP
If a malfunction is detected, the fuel
level warning light will flash repeatedly.
Have a Yamaha dealer check the vehi-
cle.
EAU72930Coolant temperature warnin g
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
a Yamaha dealer check the electrical
circuit.
NOTICE
ECA10022
Do not continue to operate the en-
g 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
7-41 for further instructions.
EAU73171Engine trou ble warnin g lig ht “ ”
This warning light comes on if a prob-
lem is detected in the engine or other
vehicle control system. If this occurs,
have a Yamaha dealer check the on-
board diagnostic system.

4 If the indicator light does not come on
initially when the key is turned to “ON”,
if the indicator light remains on, or if the
indicator light flashes in a pattern (if a
problem is detected in the immobilizer
system, the immobilizer system indica-
tor light will flash in a pattern), have a
Yamaha dealer check the vehicle.
TIP
If the immobilizer system indicator light
flashes in the pattern, slowly 5 times
then quickly 2 times, this could be
caused by transponder interference. If
this occurs, try the following.
1. Make sure there are no other im- mobilizer keys close to the main
switch. Other immobilizer system
keys may cause signal interfer-
ence and prevent the engine from
starting.
2. Use the code re-registering key to start the engine.
3. If the engine starts, turn it off, and try starting the engine with the
standard keys.
4. If one or both of the standard keys do not start the engine, take the
vehicle and all 3 keys to a Yamaha
dealer to have the standard keys
re-registered.

the lap records you can: push the “RESET” button for
one second to delete that
group of lap records.
 push the “SELECT” button
for one second to exit and re-
turn to the lap timer.
Coolant temperature display
This display indicates the temperature
of the coolant from 41 °C to 124 °C in
1 °C increments.
If the coolant temperature is between
117 and 124 °C, the coolant tempera-
ture display flashes and the coolant
temperature warning light comes on. If
this occurs, reduce the load on the en-
gine by riding at a moderate pace, at
low rpm, until the coolant temperature
goes down. If the temperature does
not go down, or if the message “HI”
flashes, stop the engine and let it cool.
(See page 7-41.)
TIP
 When the vehicle is turned on, the
coolant temperature display is au-
tomatically selected. 
When the coolant temperature is
below 41 °C, “Lo” will be dis-
played.
Air intake temperature display
This display indicates the temperature
of the air drawn into the air intake duct.
Push the “RESET” button to switch the
display between the coolant tempera-
ture and the air intake temperature.
TIP
 When the coolant temperature
display is selected, “C” is dis-
played for one second, and then
the coolant temperature is dis-
played.
 When the air intake temperature
display is selected, “A” is dis-
played for one second, and then
the air intake temperature is dis-
played.
 When the air temperature is below
–9 °C, “–9 °C” will be displayed.

Startin g the en gine
In order for the ignition circuit cut-off
system (page 4-31) 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.
To start the engine
1. Turn the key to “ON” and make sure that the engine stop switch is
set to “ ”.
2. Confirm that the following lights perform a circuit check (come on
for a few seconds and then go off). Engine trouble warning light
 ABS warning light*
 Oil level warning light
 Fuel level warning light*
 Coolant temperature warning
light
 Traction control system indi-
cator light
 Shift timing indicator light
 Immobilizer system indicator
light
TIP
 The ABS warning light should
come on and stay on until the ve-
hicle reaches a traveling speed of
10 km/h (6 mi/h).
 The fuel level warning light will
stay on if you are low on fuel.
NOTICE
ECA24110
If a warnin g or in dicator li ght does
not work as descri bed a bove, have a
Yamaha dealer check the vehicle.
3. Shift the transmission into the
neutral position (or hold the clutch
lever pulled with the sidestand up).
4. Push the start switch “ ” to crank the engine with the starter.
Release the start switch when the
engine starts, or after 5 seconds.
Wait 10 seconds before pressing
the switch again to allow battery
voltage to restore.

Coolant
The coolant level should be checked
regularly. In addition, the coolant must
be changed at the intervals specified in
the periodic maintenance chart.
TIP
If genuine Yamaha coolant is not avail-
able, use an ethylene glycol antifreeze
containing corrosion inhibitors for alu-
minum engines and mix with distilled
water at a 1:1 ratio.
EAU3908BTo check the coolant level
Since the coolant level varies with en-
gine temperature, check when the en-
gine is cold.
1. Park the vehicle on a level surface.
2. With the vehicle in an upright posi- tion, look at the coolant level in the
reservoir. 3. If the coolant is at or below the mi-
nimum level mark, remove panel B
to access the coolant reservoir.
(See page 7-7.)
4. 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.
[EWA15162]
5. Add coolant to the maximum level
mark. NOTICE: If coolant is not
availa ble, use distille d water or
soft tap water instea d. Do not
use har d water or salt water
since it is harmful to the en gine.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possi ble, other-
wise the coolin g system will not
b e protecte d a gainst frost an d
corrosion. If water has b een
a dde d to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as
soon as possi ble, otherwise the
effectiveness of the coolant will
b e red uced.
[ECA10473]
6. Install the coolant reservoir cap.
7. Install the panel.
Recommen ded coolant:
YAMALUBE coolant
Coolant quantity: Coolant reservoir (max level mark):0.25 L (0.26 US qt, 0.22 Imp.qt)
