Driving -> Road signs recognition for Your Citroen C3 Aircross SUV Second Generation (2024-2026)

This camera and its associated  
Sensors  
Mats/Pedal trims  
6
The operation of the sensors, as well as  
any associated functions, may be disrupted  
by noise pollution such as that emitted by  
noisy vehicles and machinery (e.g. lorries,  
pneumatic drills), by the accumulation of  
snow or dead leaves on the road or in the  
event of damaged bumpers and mirrors.  
When reverse gear is engaged, an audible  
signal (long beep) indicates that the sensors  
may be dirty.  
A front or rear impact to the vehicle can  
upset the sensors’ settings, which is not  
always detected by the system: distance  
measurements may be distorted.  
The sensors do not systematically detect  
obstacles that are too low (pavements,  
studs) or too thin (trees, posts, wire fences).  
Certain obstacles located in the sensors’  
blind spots may not be detected or may no  
longer be detected during the manoeuvre.  
Certain materials (fabrics) absorb sound  
waves: pedestrians may not be detected.  
The use of mats or pedal trims not  
approved by CITROËN may interfere with  
the operation of the speed limiter or cruise  
control.  
To avoid any risk of jamming the pedals:  
– Ensure that the mat is secured correctly.  
– Never fit one mat on top of another.  
functions may be impaired or not work if  
the windscreen area in front of the camera  
is dirty, misty, frosty, covered with snow,  
damaged or masked by a sticker.  
In humid and cold weather, demist the  
windscreen regularly.  
Poor visibility (e.g. inadequate street lighting,  
heavy rain, thick fog, snowfall), dazzle  
(e.g. headlamps of an oncoming vehicle, low  
sun, reflections on a damp road, leaving a  
tunnel, alternating shade and light) can also  
impair detection performance.  
In the event of a windscreen replacement,  
contact a CITROËN dealer or a qualified  
workshop to recalibrate the camera;  
otherwise, the operation of the associated  
driving aids may be disrupted.  
Units of speed  
Ensure that the units of speed  
displayed on the instrument panel (mph  
or km/h) are those for the country you are  
driving in.  
If this is not the case, when the vehicle is  
stationary, set the display to the required  
units of speed so that it complies with what  
is authorised locally.  
In case of doubt, contact a CITROËN dealer  
or a qualified workshop.  
Other cameras  
The images from the camera(s)  
displayed on the touch screen or on the  
instrument panel may be distorted by the  
terrain.  
In the presence of areas in shade, or in  
conditions of bright sunlight or inadequate  
lighting, the image may be darkened and  
with lower contrast.  
Road signs recognition  
For more information, refer to the  
General recommendations on the use  
of driving and manoeuvring aids.  
Maintenance  
Clean the bumpers and door mirrors  
and the field of vision of the cameras  
regularly.  
When washing your vehicle at high pressure,  
direct the spray from at least 30 cm away  
from the sensors and cameras.  
Obstacles may appear further away than  
they actually are.

Speed limit when  
raining  
If the wiper control  
stalk is in the  
"intermittent wipe"  
or "automatic wipe"  
position (in order  
to activate the rain  
sensor):  
Speed limit in case  
of snow  
If the outside  
temperature is  
below 3°C:  
19 mph (30 km/h)  
(for example)  
with a "snowflake"  
symbol  
Examples:  
Example:  
This system displays the maximum speed  
authorised locally on the instrument panel,  
using:  
– Speed limit signs detected by the camera.  
– Speed limit information from the connected  
services.  
– Signs indicating a shared traffic zone  
detected by the camera.  
68 mph (110 km/h)  
(for example)  
To get valid speed limit information,  
the vehicle's current position is sent  
via the telematics unit and is immediately  
deleted after processing.  
Tracking of the vehicle position is not  
possible at any time.  
Speed limit when  
towing  
If an approved  
towing device is  
fixed to the vehicle:  
56 mph (90 km/h)  
(for example)  
Sign detected  
Suggested speed  
(calculated)  
Entry into a shared  
traffic zone  
10 mph or 20 km/h  
(depending on  
the units on the  
instrument panel)  
This is not impacted by the in-vehicle privacy  
settings.  
Speed limit  
applicable over a  
certain distance  
Example:  
43 mph (70 km/h)  
(for example)  
Example:  
The units for the speed limit (mph or  
km/h) depend on the country you are  
driving in.  
This should be taken into account to ensure  
you observe the speed limit.  
For the system to work properly when  
changing countries, the speed unit of the  
instrument panel must match that of the  
country you are driving in.  
– Some supplementary traffic signs detected  
by the camera.

Driving  
Automatic sign reading is a driving aid  
system and does not always display  
the correct speed limits.  
The speed limit signs present on the road  
always take priority over those displayed by  
the system.  
The system is designed to detect signs that  
conform to the Vienna Convention on road  
signs.  
If the vehicle continues to exceed it, the speed  
is displayed and flashes for a few more seconds,  
accompanied by an audible signal.

Operating limits  
The system is active but is not detecting speed  
limit information.  
The system may not display the speed limit if  
it does not detect a speed limit sign within a  
preset period and in the following situations:  
– Non-standard road signs.  
– Road signs that are obstructed, damaged or  
bent.  
Specific speed limits, such as those for  
heavy goods vehicles, are not  
displayed.  
The display of the speed limit on the  
instrument panel is updated when passing  
a speed limit sign intended for cars (light  
vehicles).  
On detecting speed limit information, the  
system displays the value, accompanied by an  
audible signal.  
Deactivation/Activation  
By default, the overspeed alert sound is  
automatically activated at every engine start.  
This audible signal is emitted if the  
Speed limit change sound is activated  
previously in the Road Signs function of the  
instrument panel menu.  
Information displayed on  
the instrument panel  
For a suggested maximum speed, when the  
vehicle exceeds it, the speed is displayed and  
flashes for several seconds.  
Press this dashboard button to activate/  
deactivate the speed limit change sound, or via  
the instrument panel menu, using the steering-  
mounted controls (depending on version).  
1. Detected speed limit indication  
or  
2. End of speed limit indication (depending on  
version)  
The system cannot be deactivated.  
The speed limit change sound is saved  
when the ignition is switched off.
