Low Fuel Lamp/Indicator: Description and Operation
FUEL WARNING LIGHT OPERATION
To prevent the warning light from illuminating temporarily when the fuel amount is one-sided to the sub tank, the fuel warning light does not come ON
until 3 or 4 minutes have passed after the fuel level in fuel tank was lower than specified level.
Therefore, the warning light comes ON about 3 to 4 minutes after the ignition switch is turned to ON when the fuel amount in fuel tank is lower than
specified level.
