  • If you have fitted wheels not equipped with an underinflation sensor (snow tyres, etc.), consult a Citroën dealer network.
The underinflation detection system is a driving aid that does not replace the driver's vigilance or responsibility. This system does not replace regular checks of tyre pressure (see "identification") to ensure that the vehicle's dynamic behaviour remains optimal and to avoid premature tyre wear, particularly under special driving conditions (heavy load, high speed). Remember to check the pressure of the spare wheel. Any repair or tyre change on a wheel fitted with sensors must be carried out by a Citroën dealer network. The system may be temporarily disturbed by radio emissions of nearby frequencies.
