Driving -> Speed Limit recognition and recommendation for Your Citroen C5 SUV 2020

Driving  
Speed Limit recognition  
Sensors  
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 radar, sensors and  
cameras.  
and recommendation  
Refer to the General recommendations on  
the use of driving and manoeuvring aids.  
The operation of the sensors as well as  
the associated functions may be disturbed  
by sound interference such as those  
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.  
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.  
Mats  
The use of mats not approved by  
CITROËN may interfere with the operation  
of the speed limiter or cruise control.  
To avoid any risk of jamming the pedals:  
F ensure that the mat is secured  
correctly,  
This system displays the maximum authorised  
speed in the instrument panel, according to  
the speed limits in the country in which you are  
driving, using:  
F never fit one mat on top of another.

The sensors do not detect obstacles that  
are too low (pavements, studs) or too thin  
(trees, posts, wire fences).  
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.  
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.  
You should update your navigation  
mapping regularly in order to receive  
accurate speed limit information from the  
system.  
In case of doubt, contact a CITROËN  
dealer or a qualified workshop.

Speed limit in rain  
Examples:  
If the wiper control stalk is in the "intermittent wipe" or "automatic wipe" position (in order to  
activate the rain sensor):  
68 mph (110 km/h) (for example)  
Speed limit if towing  
If an approved towing device is fixed to the vehicle:  
56 mph (90 km/h) (for example)  
Speed limit applicable over a certain distance 43 mph (70 km/h) (for example)  
Example:

Driving  
Speed limit for vehicles whose gross vehicle  
weight or gross train weight is less than  
3.5 tonnes  
56 mph (90 km/h) (for example)  
Speed limit in snow  
Example:  
If the exterior temperature is below 3°C:  
19 mph (30 km/h) (for example)  
with a "snowflake" symbol  
Speed limit at certain times  
Example:  
19 mph (30 km/h) (for example)  
with a "clock" symbol  
The units for the speed limits (mph or  
km/h) depend on the country you are  
driving in.  
It should be taken into account so that you  
observe the speed limit.  
For the system to operate correctly when  
you change country, the units for speed in  
the instrument panel must be those for the  
country you are driving in.  
The automatic reading of road signs is  
a driving aid system and does not always  
display speed limits correctly.  
The speed limit signs present on the road  
always take priority in comparison with the  
display by the system.  
The system is designed to detect signs  
that conform to the Vienna Convention on  
road signs.  
Specific speed limits, such as those for  
6
heavy goods vehicles, are not displayed.  
The display of the speed limit in the  
instrument panel is updated as you pass  
a speed limit sign intended for cars (light  
vehicles).

The following situations may interfere with  
the operation of the system or prevent it from  
working:  
Activation/Deactivation  
By default, the system is automatically  
activated at every engine start.  
-
poor visibility (inadequate street lighting,  
falling snow, rain, fog),  
On detection of speed limit information, the  
system displays the value.  
The function is activated and  
deactivated in the Driving/Vehicle  
menu of the touch screen.  
-
windscreen area located in front of the  
camera dirty, misted, frost-covered, snow-  
covered, damaged or covered by a sticker,

Displays in the instrument panel  
-
speed limit signs that do not conform to the  
standard, are damaged or distorted.  
For a suggested maximum speed, the first  
time that the vehicle's speed exceeds it by  
more than 3 mph (5 km/h) (example: 59 mph  
(95 km/h)), the speed flashes for 10 seconds.
