Driving
The vehicle stalls in STOP mode
All of the instrument panel warning lamps come
on if there is a fault.
The Stop & Start system requires a 12 V battery of specific technology and
specification.
All work concerning the battery must be
carried out only by a CITROËN dealer or a
qualified workshop.
Tyre under-inflation detection
This system automatically checks the pressures
of the tyres while driving.
It compares the information given by the wheel
speed sensors with reference values, which
must be reinitialised every time the tyre
pressures are adjusted or a wheel changed.
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one or
more tyres.
Under-inflation detection does not
replace the need for vigilance on the part
of the driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel) as well as before a long
journey.
Operation
Main conditions for operation
– The driver ’s door must be closed.
– The driver's seat belt must be fastened.

Driving
Speed Limit Recognition
and Recommendation
Refer to the General recommendations on the
use of driving and manoeuvring aids.


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:
– Speed limit signs detected by the camera.
– Speed limit details from the navigation system
mapping.
Navigation mapping should be regularly
updated in order to receive accurate
speed limit information from the system.
– Signs indicating an intersection area detected
by the camera.
If the front bumper is to be repainted, contact
a CITROËN dealer or a qualified workshop;
certain types of paint could interfere with the
operation of the radar.


Driving aids camera
This camera and its associated 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 (inadequate street lighting,
heavy rain, thick fog, snowfall), dazzle
(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.
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.
Obstacles may appear further away than they
actually are.
Sensors
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.
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.
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:
–

Ensure that the mat is secured correctly
.
–

Never fit one mat on top of another
.
Units of speed
Ensure that the units of speed displayed
in 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.

– Road signs that are obstructed, non-standard,
damaged or bent.
– Obsolete or incorrect maps.
Recommendation

In addition to Speed Limit Recognition and
Recommendation, the driver can select the
speed displayed as a speed setting for the speed
limiter or cruise control using the speed limiter or
cruise control 'store' button.
For more information on the Speed
limiter, Cruise control or Adaptive
cruise control, refer to the corresponding
sections.

detected Display of the
speed associated with the qualifier plate
Speed limit at certain times Example:


19 mph (30 km/h)
(for example)
with a "clock" symbol
The units for the speed limit (mph or km/h) depend on the country you are
driving in.
This should be taken into account so that you
observe the speed limit.
For the system to work correctly when
changing country, the speed unit in the
instrument panel must correspond to that of
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 over 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
heavy goods vehicles, are not displayed.
The display of the speed limit in the
instrument panel is updated when passing
a speed limit sign intended for cars (light
vehicles).
Activation / Deactivation
By default, the system is automatically activated
at every engine start.
It is set via the Driving / Vehicle touch
screen menu.

or a qualified workshop.
Cruise control - particular
recommendations
For the safety of everyone, only use the
cruise control where the driving
conditions allow running at a constant speed
and keeping an adequate safety distance.
Remain vigilant when the cruise control
is activated. If you hold one of the speed
setting modification buttons down, a very
rapid change in the speed of your vehicle may
occur.
When descending a steep hill , the cruise
control system cannot prevent the vehicle
from exceeding the set speed. Brake if
necessary to control the speed of your
vehicle.
On steep climbs or when towing, the set
speed may not be reached or maintained.
Exceeding the programmed speed
setting
You can temporarily exceed the speed
setting by pressing the accelerator pedal (the
programmed speed flashes).
To return to the speed setting, release the
accelerator pedal (when the set speed is
reached again, the displayed speed stops
flashing).
Operating limits
