Fuel Level Display (911 Carrera 4 & GT3)
If power supply is interrupted by a discharge, or battery disconnect, with fuel tank containing less than 5 gallons (19 liters), calculated value for range on remaining fuel in instrument cluster, will be incorrect or deleted.
If fuel tank contains less than 2.5 gallons (10 liters), it is possible that fuel level warning light is no longer activated. If power supply is restored, with fuel level less than 5 gallons (19 liters), it is possible that fuel level display may display too much. This may lead to vehicle breaking down (running out of gas).
Refill fuel tank. Fuel level sensor is within operating range, and display more accurate.
