Detection of road signs

The system displays speed limits on the instrument panel according to road signs detected on the side of the road.
It mainly uses information taken from the camera 1 attached to the windscreen behind the rear view mirror. Depending on the country, the system also uses information from a map subscription to interpret certain signs (town entrance, etc.).
The sign displayed on the instrument panel changes when a road sign is detected by the system.
Once the speed limiter, the cruise control or the adaptive cruise control is activated, you can adapt the limited speed setpoint to the speed displayed on the instrument panel by the system (SPEED LIMITER, CRUISE CONTROL and ADAPTIVE CRUISE CONTROL).
If the detected limit speed is exceeded, the road sign display is modified to inform you.

Location of the camera 1

Make sure the windscreen is not obscured (by dirt, mud, snow, condensation etc.).

Special features

For vehicles with a map subscription:
  • if the vehicle is travelling in a country where the speed units differ from those of the vehicle, the system displays the speed limit sign in the unit of the country, alongside the speed limit converted to the unit used by the vehicle’s instrument panel.
  • for countries where the speed limit is reduced during rainy weather on some types of roads, the system may alter the detected speed limit after a few seconds of the windscreen wipers being activated.
For vehicles without a map subscription: when driving in a country where speed units differ from those on your vehicle, you can manually select the speed unit shown on the instrument panel (e.g. change the unit from miles to kilometres) in order to display accurate information DISPLAYS AND INDICATORS.
The system does not take into account exceptional speed limit measures, such as peak pollution days.
