The warning lamp should go off when the engine is started.
If it does not go off, contact a CITROËN dealer or qualified
workshop without delay.
You must refuel as soon as possible to avoid running
out of fuel.
This warning lamp will come on every time the ignition is

Fuel tank capacity: approximately 50 litres (petrol),
46 litres (Diesel) or 33 litres (LPG); depending on

Stop as soon as it is safe to do so.
Wait until the engine has cooled down before topping
up the level, if necessary.
If the problem persists, contact a CITROËN dealer or
qualified workshop.
