rear of the vehicle,
-

m
onitor the activity of your passengers,
particularly any children.
Bicycle carrier/Towing device
The motorised tailgate is not designed to
support a bicycle carrier.
When installing a
bicycle carrier on a towing
device with connection of a
cable to the towing
socket, the motorised operation of the tailgate
will be automatically deactivated.
If using a
towing device or bicycle carrier not
recommended by CITROËN, it is essential
to deactivate the motorised operation of the
tailgate.
Motorised operation
Activation/deactivation of the
motorised operation of the tailgate is
done in the Driving/Vehicle menu of
the touch screen. There are several ways of operating the
tailgate:Opening/Closing
F Press and hold the central button A of the
electronic key.
or
F

P

by default, or to the position memorised
beforehand.
If motorised operation is not activated,
these actions release the tailgate.
The request to open the tailgate with one
of the controls A
, B or E enables you to
unlock the vehicle or the tailgate alone
beforehand, if selective unlocking of the
boot is activated.
Closing the tailgate with the "hands-free"
access function enables you to lock the
vehicle.
This function is deactivated by default. A.
using the electronic key of the Keyless
Entry and Starting system,

It is possible to interrupt the operation of
the tailgate at any point.
Pressing one of these controls again
interrupts the movement that is under way.
Following the interruption of a movement,
pressing one of these controls again
reverses the movement.
" Hands-Free Tailgate Access "
The "Hands-Free Tailgate Access"
function is activated/deactivated in
the Driving/Vehicle menu of the
touch screen.
Ensure that you are steady on your
feet before per forming the quick foot
movement.

Automatic locking using the " Hands-
Free Tailgate Access " function
Memorising an opening
position
To memorise a position, in order to limit the
motorised tailgate opening angle:
F

m
ove the tailgate to the desired position
manually or by pressing the button,
F

p
ress button C or the exterior control B
for more than 3


seconds (memorisation is
confirmed by a
brief audible signal).
Saving is not available until the height of
opening is more than or equal to 1
metre
between the low position and the high
position of the tailgate. To delete
the memorised position:
F
o
pen the tailgate to any position,
F
p
ress button C or the exterior control B
for more than 3 seconds (the deletion is
confirmed by a long audible signal).
Manual operation
The tailgate can be manoeuvred by hand, even
with motorised operation activated.
The tailgate must be stationary.
When opening and closing a


motorised tailgate
manually, there is no assistance from gas
struts. Resistance to opening and closing is
therefore entirely normal.
This function is deactivated by default. Press this button to activate/deactivate
automatic locking of the vehicle when closing
the tailgate using the "Hands-Free Tailgate
Access" function (confirmed by lighting/
extinction of the green indicator lamp).
Repeatedly opening and closing the
motorised tailgate can cause overheating
of its electric motor, after which opening
and closing will not be possible.
Allow at least 10
minutes for the electric
motor to cool down before operating the
tailgate again.
If you are unable to wait, operate it
manually.

Manual closing of the
motorised tailgate in case
of failure
This operation is only necessar y in the case
of failure of the tailgate motor.
If the failure originates from the battery, it is
recommended to recharge it or change it with
the tailgate closed .
In this situation, a significant force may be
needed to close the tailgate.
F

C
lose it gently without slamming, as slowly
as possible, by pushing at the centre of the
tailgate.
Do not lower the tailgate by pushing at one
of its sides – risk of damage!
Precautions in use
To avoid unwanted opening of the tailgate
when using the towing device:
-

d
eactivate the "Hands-Free Tailgate
Access" function in advance in your
vehicle's configuration menu,
-

o
r remove the electronic key from the
recognition zone, with the tailgate
closed. In wintry conditions
To avoid any operating problems, remove
the snow or wait until the ice melts before
requesting motorised opening of the
tailgate.
When washing
When washing the vehicle in an automatic
car wash, do not forget to lock your vehicle
to avoid the risk of unexpected opening.
Recommendations related
to the "
Hands-Free Tailgate
Access " function
If several kicking movements to operate the
tailgate have no effect, wait a
few seconds
before trying again.
The function automatically deactivates in heavy
rain or following a
build-up of snow.
If it does not work, check that the electronic key
is not exposed to a
source of electromagnetic
pollution (smartphone, etc.).
The function may not work correctly with
a


prosthetic leg. The function may not work correctly if your
vehicle is fitted with a
towing device.
In some circumstances, the tailgate may open
or close by itself, particularly if:
-
y
ou hitch or unhitch a trailer,
-
y
ou fit or remove a bicycle carrier,
-
y
ou load or unload bicycles from a bicycle
c a r r i e r,
-
y
ou place or lift something behind the

-
an
animal approaches the rear bumper,
-
y
ou are washing your vehicle,
-
y
our vehicle is being serviced,
-
y
ou are accessing the spare wheel
(depending on version).
To avoid such operating problems, keep the
electronic key away from the recognition zone
or deactivate "Hands-Free Tailgate Access".
After installing a towing device, it is
essential to contact a
CITROËN dealer
or a
qualified workshop so that it is taken
into account by the detection system.
Other wise, risk of "Hands-Free Tailgate
Access" function failure.

The display is immediately updated with the
type of view selected.
The state of the function is not saved when the
ignition is switched off.
Principle of operationThe screen is divided into two parts: on the
left, a contextual view; on the right, a view from
above the vehicle in its close surroundings.
The parking sensors supplement the
information on the view from above the vehicle.
AUTO mode is activated by default.
In this mode, the system chooses the best view
to display (standard or zoom) according to the
information from the parking sensors.
You can change the type of view at any time
during a


manoeuvre. Using one or two cameras, the close
surroundings of the vehicle are recorded whilst
manoeuvring at low speed.
An image from above your vehicle in its close
surroundings is reconstructed (represented
between the blue brackets) in real time and as
the manoeuvre progresses.
This representation facilitates the alignment of
your vehicle when parking and allows obstacles
close to the vehicle to be seen. With Top 360
Vision, the image is created using
both cameras, when going for ward and when
reversing.
When the function is activated, it is possible
that the view from above is not displayed. If
the system is activated when the vehicle has
already moved, the view from above can be
fully displayed.Top Rear Vision

Vehicle equipped with motorised tailgate
with " Hands-Free Tailgate Access "
function
To avoid unwanted opening of the tailgate
when using the towing device:
-

d
eactivate the "Hands-Free Tailgate
Access" function in advance in your
vehicle's configuration menu,
-

o
r remove the electronic key from the

Towing device
Load distribution
F Distribute the load in the trailer so that the
heaviest items are as close as possible to
the axle and the nose weight approaches the
maximum permitted without exceeding it.
Air density decreases with altitude, thus
reducing engine performance. The maximum
towed load must be reduced by 10% for every
1,000
metres of altitude. Use towing devices and their genuine
harnesses approved by CITROËN. It
is recommended that the installation
be per formed by a
CITROËN dealer or
a

qualified workshop.
If the towing device is not fitted by
a CITROËN dealer, it must still be
fitted in accordance with the vehicle
manufacturer's instructions.
Important: for versions equipped with
the motorised tailgate with Hands-Free
Tailgate Access function, if a
towing
device other than a
genuine CITROËN
one is installed, it is essential to visit
a
CITROËN dealer or a qualified
workshop to recalibrate the detection
system: risk of "Hands-Free Tailgate
Access" function failure.
Certain driving or manoeuvring aid
functions are automatically disabled if an
approved towing system is used.
