The start of saturation of the particle filter is indicated by the temporary illumination of this warning lamp accompanied by a warning message in the screen.

As soon as the traffic conditions permit, regenerate the filter by driving at a speed of at least 40 mph (60 km/h) until the warning lamp goes off.

If the warning lamp stays on, this indicates a low additive level.

On a new vehicle, the first particle filter regeneration operations may be accompanied by a "burning" smell, which is perfectly normal.

Following prolonged operation of the vehicle at very low speed or at idle, you may, in exceptional circumstances, notice the emission of water vapour at the exhaust on acceleration. This does not affect the behaviour of the vehicle or the environment.
