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

minutes. If the warning light does not go off,
stop the engine and allow it to cool. (See page
9-61.)

temperature warning light goes off, release

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.
