Coolant temperature warning light “
”
This warning light comes on when the coolant
temperature, and therefore the engine, is out-
side its normal operating temperature range.
The warning light comes on in blue to inform
the driver that the vehicle should be warmed
up. After the engine is started, warm it up until
the warning light goes off.
The vehicle can be operated normally when
the warning light is off.
The warning light comes on in red when the
engine is overheating. If the red light comes
on, stop the vehicle as soon as it is safe to do
so and allow the engine to idle for about 10
minutes. If the warning light does not go off,
stop the engine and allow it to cool. (See page
9-61.)
TIP
When the coolant temperature is too cold,
engine power is restricted. After the coolant
temperature warning light goes off, release
the accelerator pedal, and then the vehicle
will switch to normal operating mode.
If you continue to drive the vehicle while the
engine is overheating, a buzzer will sound.
The coolant temperature warning light can
be checked by turning the key to “
” (on).
The warning light should come on in purple
briefly (which confirms that both the blue
and red indicators are okay) and then go
off. If the warning light does not come on at
all, comes on in red or blue, or if the warning
light remains on, have a Yamaha dealer
check the vehicle.
NOTICE
ECB02040
The engine may overheat if the vehicle is
overloaded. If this happens, reduce the
load to specification.
