The function will re-engage when your speed returns below the de-sired maximum speed.
Disengagement of the maximum speed
Press on button 3.
This action causes the information "OFF" to appear on the instru-ment panel screen.
Use of fl oor mats that are not approved by CITROËN may hinder access to the accelerator pedal and thus interfere with the func-tioning of the speed limiter.
To avoid any risk of interfering with the pedals :
- check that the fl oor mat is correctly positioned,
- never use more than one fl oor mat.
This action does not cancel the memorised maximum speed which remains displayed in zone A ofthe instrument panel.

Complementary to the catalytic converter, this fi lter makes an active contribution to the preservation of air quality by the retaining of the unburnt pollutant particles. Black exhaust fumes are thus no longer emitted.
Clogging of the particle fi lter
If there is risk of clogging, a message appears on the multifun ction display, accompanied by a sound signal and lighting of the SERVICE warning lamp.
This alert tells you that the particle fi lter is starting to fi ll up (in conditions of urban driving of exceptionally lon g dura-tion: low speeds, traffi c jams etc.)
To regenerate the fi lter, it is advised to drive as soon as p ossible, when traffi c conditions permit, at a speed of 60 km/h (around 40 mph) or more for at least fi ve minutes (until t he alert message disappears).
If this alert persists, consult a CITROËN dealer.
Observation : After prolonged idling or driving at very low speeds, you may occa sionally notice water vapour be-ing emitted from the exhaust when accelerating. This is of no consequence to the running of the vehicle or to the environment.
Diesel fuel additive level
If the additive level becomes too low, a message appears on the multifunction display, accompanied by a sound signal and lighting of the SERVICE warning lamp. It is necessa ry to have the additive level topped up. Urgently consult a CITROËN dealer.signal and lighting of the SERlighting of
