TIP
This model is equipped with a lean an-
gle sensor to stop the engine in case
o\b a turnover. In this case, the multi-
\bunction display indicates error code
30, but this is not a mal\bunction. Turn
the key to "OFF" and then to "ON" to
clear the error code. Failing to do so
will prevent the engine \brom starting
even though the engine will crank
when pushing the st\sart switch.

Engine overheatingEWA10400
W\fRNING0
●Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cau\Mse serious injury. Be sure to wait until th\Me engine has coole\Md.
●\ffter removing the radiator cap retaining bolt, place a thick rag, like a towel, over the radiator cap, and then
slowly rotate the cap counterclockwise to the detent to allow any residual pressure to escape. When the hiss-
ing sound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.
TIP
If coolant is not a\failable, ta\b water can be tem\borarily used instead, \bro\fided that it is changed to the recommended
coolant as soon as \b\sossible.
Wait until the
engine has cooled.Check the coolant le\fel
in the reser\foir and radiator.
The coolant le\fel is low.
Check the cooling
system for leakage.
The coolant le\fel
is OK.
There is
leakage.
There is no
leakage.
Ha\fe a Yamaha dealer check
and re\bair the cooling system.
Start the engine. If the engine o\ferheats again, ha\fe
a Yamaha dealer check and re\bair the coo\sling system.
Add coolant. (See TIP.)
