EAU15951
Read the Owner’s Manual carefully to
become familiar with all controls. If
there is a control or function you do not
understand, ask your Yamaha dealer.
WARNING

TIPThis model is equipped with:

a lean angle sensor to stop the en-
gine in case of a turnover. In this
case, the multi-function display in-
dicates error code 30, but this is
not a malfunction. Turn the key to
“OFF” and then to “ON” to clear the
error code. Failing to do so will pre-
vent 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 multi-function display indicates
error code 70, but this is not a mal-
function. Push the start switch to
clear the error code and to restart
the engine.
EAU45125
Starting the engine In 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 3-19 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
should come on for a few seconds,
then go off.

Fuel level warning light


Coolant temperature warning
light


Engine trouble warning light

If a warning light does not come on
initially when the key is turned to
“ON”, or if a warning light remains
on, see page 3-2 for the correspond-
ing warning light circuit check.

Coolant The 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.
EAU20253
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 temperature.


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 cool-
ant reservoir.TIPThe coolant should be between the
minimum and maximum level marks.
3. If the coolant is at or below the
minimum level mark, remove pan-
el C (See page 6-7.), remove the
reservoir cap, add coolant to the
maximum level mark, and then in-
stall the reservoir cap and the pan-
el. WARNING! Remove only the
coolant reservoir cap. Never at-
tempt to remove the radiator
cap when the engine is hot.
[EWA15161]
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-

6 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
be reduced.
[ECA10472]EAU45155
To change the coolant
1. Place the vehicle on a level sur-
face and let the engine cool if nec-
essary.
2. Remove panels A and C. (See
page 6-7.)
3. Place a container under the engine
to collect the used coolant.
4. Remove the radiator cap retaining
bolt and radiator cap. WARNING!
Never attempt to remove the ra-
diator cap when the engine is
hot.
[EWA10381]
5. Remove the coolant reservoir by
removing the bolts.6. Remove the coolant reservoir cap.
7. Drain the coolant from the coolant
reservoir by turning it upside down.
8. Install the coolant reservoir by
placing it in the original position,
and then installing the bolts.

its gasket to drain the cooling sys-
tem.
10. After the coolant is completely
drained, thoroughly flush the cool-
ing system with clean tap water.
11. Install the coolant drain bolt and its
new gasket, and then tighten the
bolt to the specified torque.
12. Pour the specified amount of the
recommended coolant into the ra-
diator and reservoir.13. Install the coolant reservoir cap.
14. Install the radiator cap.
15. Start the engine, let it idle for sev-
eral minutes, and then turn it off.
16. Remove the radiator cap to check
the coolant level in the radiator. If
necessary, add sufficient coolant
until it reaches the top of the radia-
tor, and then install the radiator
cap and its retaining bolt.
17. Check the coolant level in the res-
ervoir. If necessary, remove the
coolant reservoir cap, add coolant
to the maximum level mark, and
then install the cap.18. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.
