2020 CITROEN C4 parking sensors

132
Driving
Zoom view

The camera records the vehicle's surroundings
during the manoeuvre in order to create a
view from above the front of the vehicle in its
near surroundings, allowing the vehicle to be
manoeuvred around obstacles nearby.
This view is available with AUTO mode or in the
view selection menu.
Obstacles may appear further away than
they actually are.
It is important to check the sides of the
vehicle during the manoeuvre, using the
mirrors.
The parking sensors also supplement the
information on the vehicle's surroundings.
180° view

The 180° view assists with exiting from a parking
space in forward gear, making it possible to
see the approach of vehicles, pedestrians and
cyclists.
This view is not recommended for carrying out a
complete manoeuvre.
It consists of 3 areas: left A, centre B and right
C.
This view is available only from the view
selection menu.
Park Assist
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .
This system provides active parking assistance:
it detects a parking space and then steers in the
appropriate direction to park in the space while
the driver controls the driving direction, gear
changes, acceleration and braking.
To help the driver monitor the manoeuvre, the
system automatically triggers the display from
the Top Rear Vision or 360 vision function and
activates the parking sensors.
The system measures the available parking
spaces and calculates the distances to obstacles
using ultrasonic sensors built into the front and
rear bumpers of the vehicle.


The system assists with the following
manoeuvres:
A. Entering a "parallel" parking space
B. Leaving a "parallel" parking space
C. Entering a "bay" parking space

Driving
6Operation
► When approaching a parking area, reduce
the speed of your vehicle to 19 mph (30 km/h)
or less.
Activating the function
The function is activated in the Vehicle/ Driving touch screen menu.
Select "Park Assist".
Activating the function deactivates the Blind spot monitoring system.
You can deactivate the function at any time until the parking space entry or exit
manoeuvre begins, by pressing the arrow
located in the top left-hand corner of the
display page.
Selecting the type of manoeuvre

A manoeuvre selection page is displayed on the
touch screen: by default, the "Entry" page if the
vehicle has been running since the ignition was
switched on, otherwise, the "Exit" page.
►

Select the type and side of the manoeuvre to
activate the parking space search.
The selected manoeuvre can be changed at
any time, even while searching for an available
space.
This indicator lamp comes on to confirm the selection.
Parking space search
► You should drive at a distance of between
0.50 m and 1.50 m from the row of parked
vehicles, without ever exceeding 19
mph
(30
km/h), until the system finds an available
space.
The parking space search stops over this limit.
The function automatically deactivates once the
vehicle speed exceeds 31 mph (50
km/h).
For ''parallel'' parking, the space must at
a minimum be equal to the length of your
vehicle plus 0.60 m.
For ''bay'' parking, the width of the space
must be equal to the width of your vehicle
plus 0.70 m.
If the parking sensors function has been
deactivated in the Driving/Vehicle menu
of the touch screen, it will be automatically
reactivated when the system is activated.


When the system finds an available space, " OK"
is displayed on the parking view, accompanied
by an audible signal.
Preparing for the manoeuvre
► Move very slowly until the request to stop
the vehicle is displayed: " Stop the vehicle",
accompanied by the " ST
OP" sign and an audible
signal.
Once the vehicle has stopped, an instructions
page is displayed on the screen.
►

T
o prepare for the manoeuvre, follow the
instructions.
The start of the manoeuvre is indicated by
the message
"Manoeuvre under way",
accompanied by an audible signal.

Driving
6– The system may indicate that a space has
been found but will not offer it because of a fixed
obstacle on the opposite side of the manoeuvre,
which would not allow the vehicle to follow a
trajectory required for parking.
–

The system may indicate that a space has
been found but the manoeuvre will not be
triggered, because the width of the lane is
insufficient.
–


The system is not designed for performing the
parking manoeuvre on a sharp bend.
–


The system does not detect spaces that
are much larger than the vehicle itself or that
are delimited by obstacles that are too low
(pavements, studs, etc.) or too thin (trees, posts,
wire fences, etc.).
–


If the boot is heavily loaded, the tilt of the
vehicle towards the rear may interfere with the
distance measurements.
Do not use the function under the
following exterior conditions:
–

Alongside a soft shoulder (e.g. ditch) or
quay or on the edge of a drop.
–


When the road surface is slippery (e.g. ice).
If any of the following malfunctions
occurs, do not use the system:
–

If a tyre is under-inflated.
–


If one of the bumpers is damaged.
–


If one of the cameras is faulty
.
If the vehicle has undergone any of the
following modifications, do not use the
function:
–

When carrying an object extending beyond
the dimensions of the vehicle (ladder on the
roof bars, bicycle carrier on the tailgate, etc.).
–


With a non-approved towball in place.
–


With snow chains fitted.
–


When driving on a small-diameter or
"space-saver" type spare wheel.
–


When the wheels fitted are a different size
from the original ones.
–


After modifying one or both bumpers
(added protection).
–


If the sensors have been repainted other
than by the CITROËN dealer network.
–


With sensors not approved for the vehicle.
Malfunctions
When the function is not activated, this
indicator lamp will flash briefly and an
audible signal will be emitted to indicate a
system malfunction.
If the malfunction occurs while the system is in
use, the warning lamp goes off.
If the parking sensor malfunction occurs
during use, indicated by this warning lamp
coming on and the display of a message, it
causes the function to deactivate.
In the event of a malfunction, have the system
checked by a CITROËN dealer or a qualified
workshop.
In the event of a power steering
malfunction, this warning lamp is
displayed on the instrument panel, accompanied
by a warning message.
You must stop as soon as it is safe to do so.

Advice on care and maintenance
General recommendations
Observe the following recommendations to avoid
damaging the vehicle.
Exterior
Never use a high-pressure jet wash in
the engine compartment - risk of
damaging the electrical components!
Do not wash the vehicle in bright sunshine or
extremely cold conditions.
When washing the vehicle in an
automatic roller-brush car wash, be sure
to lock the doors and, depending on version,
move the electronic key away.
When using a pressure washer, keep the jet
nozzle at a minimum distance of 30 cm from
the vehicle (particularly when cleaning areas
containing chipped paint, sensors or seals).
Promptly clean up any stains containing
chemicals liable to damage the vehicle's
paintwork (including tree resin, bird
droppings, insect secretions, pollen and tar).
Depending on the environment, clean the
vehicle frequently to remove salty deposits
(in coastal areas), soot (in industrial areas)
and mud/salts (in wet or cold areas). These
substances can be highly corrosive.
Contact a CITROËN dealer or a qualified
workshop for advice on removing stubborn
stains requiring special products (such as tar
or insect removers).
Preferably, have paint touch-ups performed
by a CITROËN dealer or a qualified
workshop.
Interior
When washing the vehicle, never use a
water hose or high-pressure jet to clean
the interior.
Liquids carried in cups or other open
containers can spill, presenting a risk of
damage to the instruments and controls and
the controls located on the centre console. Be
vigilant!
