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 or the cruise control is activated, you can adapt the limited speed setpoint to the speed limit displayed on the instrument panel by the system (SPEED LIMITER and CRUISE CONTROL).
If the detected speed limit is exceeded, the road sign displayed on the instrument panel is modified to inform the driver.

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.
On vehicles not fitted with a navigation system: when driving in a country where the speed units differ from that of your vehicle, you can manually select the relevant speed unit on the instrument panel (e.g. change from miles to kilometres) in order to obtain the appropriate informationDISPLAYS AND INDICATORS.
Note:
The system does not take into account exceptional speed limit measures, such as peak pollution days.
Tip
Road sign detection is associated with a map subscription.
If there is no subscription, the system will be limited to taking into account the speed limit signs when they are detected by the camera.
The system will no longer take into account information related to the maps. The speed limit availability may be affected.
Depending on the equipment, it is necessary to update the maps regularly. It the maps are not updated, system performance will be impaired.
To manage the subscription, please refer to the multimedia instructions.

Operation

Warning lights

The function displays the following warning lights:

Speed limit signs and additional speed limit signs (speed on exit ramp with arrow, speed with a caravan, speed limit with length of application, etc.)

Additional road signs (start of no overtaking zone).
If the detected speed limit is exceeded, a circle flashes around the road sign (warning light 2) accompanied, depending on the vehicle, by a beep emitted for a few seconds to warn you.
It remains illuminated on the instrument panel as long as the vehicle speed is exceeding the speed limit.
Tip
Map subscription

Note: if there is no map for a country, a message will appear on the multimedia screen to inform of this and suggest downloading the map information relating to the country.
To manage the subscription, please refer to the multimedia instructions.
If there is no subscription, the system will be limited to taking into account the speed limit signs when they are detected by the camera.

Warning

WARNING
This function is an additional driving aid. This function is not under any circumstances intended to replace the due care and attention of the driver, who should at all times be in control of the vehicle.
The driver should always adapt their speed to the traffic conditions, regardless of the system indications.
The system detects speed limit signs and does not detect other signs (e.g. entry to/exit from urban areas, etc.).
The system may not detect all speed limit signs or may interpret them incorrectly.
The driver must not ignore road signs undetected by the system and should give priority to complying with the actual road signs and the highway code.
In the event of poor visibility (fog, snow, frost, etc.), it is possible that the system may not indicate the correct speed to the driver.
The driver should always adapt their speed to the traffic conditions, regardless of the system indications.
