Citroen C3: Driving / Under-inflation detection

Citroen C3 2016-2022 Owners Manual / Driving / Under-inflation detection

This system automatically checks the pressures of the tyres while driving.

It compares the information given by the wheel speed sensors with reference values, which must be reinitialised every time the tyre pressures are adjusted or a wheel changed.

The system triggers an alert as soon as it detects a drop in the inflation pressure of one or more tyres.

Citroen C3. Under-inflation detection Under-inflation detection does not replace the need for vigilance on the part of the driver.

This system does not avoid the need to regularly check the tyre pressures (including the spare wheel) as well as before a long journey.

Driving with under-inflated tyres, particularly in adverse conditions (heavy load, high speed, long journey):

  • worsens road-holding.
  • lengthens braking distances.
  • causes premature wear of the tyres.
  • increases fuel consumption.

Citroen C3. Under-inflation detection The inflation pressures defined for the vehicle can be found on the tyre pressure label.

For more information on the Identification markings, refer to the corresponding section.

Citroen C3. Under-inflation detection Checking tyre pressures

This check should be done when the tyres are "cold" (vehicle stopped for 1 hour or after a journey of less than 6 miles (10 km) at moderate speeds).

Otherwise, add 0.3 bar to the pressures shown on the label.

Citroen C3. Under-inflation detection Snow chains

The system does not have to be reinitialised after fitting or removing snow chains.
