~1min read

If the needle is in the following position with the engine running:
- in zone A, the temperature is correct,
- in zone B, the temperature is too high; the maximum temperature warning light 1 and the STOP central warning light illuminate red, an audible signal sounds, and a message appears on the multifunction display.
Stop the vehicle immediately in a safe place.
Wait a few minutes before switching off the engine.
Contact a CITROËN dealership or a qualified workshop.
After a few minutes of driving, the temperature and pressure in the cooling system increase.
To top up the level:
- wait for the engine to cool down,
- turn the cap two turns to release the pressure,
- if the pressure drops, remove the cap,
- top up the level to the "MAXI" mark.
