The deflation detection system is a driving assistance function which does not absolve the driver from the responsibility to be vigilant, or from the need to check the tyre pressures regularly (see "Vehicle identification").

This system does not absolve the driver of the need to check the tyre pressures on a regular basis (see "Identification"), to ensure that the vehicle behaves as it should and to avoid premature wear on the tyres, especially when the vehicle is being subjected to heavy loads or driven at high speeds.

Do not forget to check the tyre pressure on the spare wheel.

Any repair or any change of tyre, on a wheel fitted with a sensor, should be carried out by a CITROËN Dealer. The system may be affected from time to time by interference from radio transmissions on similar frequencies.
