FUEL GAUGE
The fuel level is tested each time the key is
turned to the "running" position.
The gauge is positioned on:
- F (Full): the capacity of the fuel tank is
approximately 45 litres .

In arduous conditions of use or hot climatic
conditions, the needle may move close to
the red graduations. - wait approximately 15 minutes to allow
the engine to cool down in order to check
the level and top it up if necessary. The
cooling system is pressurised. In order to
avoid any risk of scalding, unscrew the
cap by two turns to allow the pressure to
drop.
When the pressure has dropped, check the
level and remove the cap to top up.
If the needle remains in the red zone,
contact a CITROËN dealer. EOBD (European On Board Diagnosis) is

board), remove the key from the ignition when
leaving the vehicle, even for a short time.
