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 6-10), 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 repeat-
edly. Have a Yamaha dealercheck the vehicle.

Coolant temperature warning light
“”
This warning light comes on if the en-
gine overheats. If this occurs, stop the
engine immediately and allow the en-
gine to 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

TIPThis model is equipped with:
a lean angle sensor to stop the en-
gine in case of a turnover. In this
case, the engine trouble warning
light will come on, but this is not a
malfunction. Turn the key to “OFF”
and then to “ON” to turn off the
warning light. 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. If the engine
stops, simply push the start switchto restart the engine.
EAU73430
Starting the engineIn 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 sid-
estand up.
See page 3-28 for more informa-
tion.
1. Turn the key to “ON” and make sure that the start/engine stop
switch is set to “ ”.
The following warning lights and
indicator light should come on for a
few seconds, then go off.

CoolantThe coolant level should be checked
regularly. In addition, the coolant must
be changed at the intervals specified in
the periodic maintenance chart.TIPIf genuine Yamaha coolant is not avail-
able, use an ethylene glycol antifreeze
containing corrosion inhibitors for alu-
minum engines and mix with distilledwater at a 1:1 ratio.
EAU20097
To 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 minimum level mark, remove the
coolant reservoir cap. WARNING!
Remove only the coolant reser-
voir cap. Never attempt to re-
move the radiator cap when the
engine is hot.
[EWA15162]
4. Add coolant to the maximum level mark. NOTICE: If coolant is not
available, use distilled water or
soft tap water instead. Do not
use hard water or salt water
since it is harmful to the engine.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the cooling system will not
be protected against frost and
corrosion. If water has been
added to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as
soon as possible, otherwise the
effectiveness of the coolant will
Recommended coolant: YAMALUBE coolant
Coolant quantity: Coolant reservoir (max level mark): 0.25 L (0.26 US qt, 0.22 Imp.qt)
