TIP
This model is equipped with a lean an-
gle sensor to stop the engine in case
of a turnover. In this case, the multi-
function display indicates 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 prevent the engine from starting
even though the engine will crank
when pushing the start switch.
EAUB1570
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.
EWA10290
WARNING0

Engine overheatingEWA10400
WARNING0
●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 cause serious injury. Be sure to wait until the engine has cooled.
●After 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 available, tap water can be temporarily used instead, provided that it is changed to the recommended
coolant as soon as possible.
Wait until the
engine has cooled.Check the coolant level
in the reservoir and radiator.
The coolant level is low.
Check the cooling
system for leakage.
The coolant level
is OK.
There is
leakage.
There is no
leakage.
Have a Yamaha dealer check
and repair the cooling system.
Start the engine. If the engine overheats again, have
a Yamaha dealer check and repair the cooling system.
Add coolant. (See TIP.)
