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.

Speed limit signs detected by the camera.
Speed limit details from the navigation
system mapping.

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:
138
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).

Driving
The following situations may interfere with
the operation of the system or prevent it from
working:
Activation/Deactivation
