2To avoid the risk of injury through pinching or trapping, before and during
operation of the motorised tailgate:
–

ensure that there is no-one close to the
rear of the vehicle.
–


monitor the activity of the rear 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 the towing
device with connection of the cable to the trailer
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
The motorised operation of the tailgate is configured in the Settings
> Vehicle
touch screen application.


There are several ways of operating the tailgate:
A. Using the Keyless Entry and Starting
system’s electronic key
B. Using the exterior tailgate control
C. Using the interior tailgate control
D. Using the control on the dashboard
Opening
► A long press on the central button A of the
electronic key.
or
►

A
short press on the exterior tailgate control
B, with the electronic key on your person.
or
►

T
wo consecutive presses on the control D on
the dashboard.
The tailgate opens, either completely by default, or to the position memorised
beforehand.
If motorised operation is not activated, these
actions release the tailgate (partially-open
position).
When the vehicle is locked, the request to
open the boot with one of the controls A
or B unlocks the vehicle, or only the boot if
selective unlocking is activated, prior to the
opening of the boot.
Closing
► A short press on the interior tailgate control C.
It is possible to interrupt the operation of
the tailgate at any point.
Pressing one of these controls again
interrupts the movement that is underway.
Memorising an opening
position
To limit the opening angle of the motorised
tailgate:
►

move the tailgate to the desired position
manually or by pressing the button.
►


press button
C or the exterior control B for
more than 3 seconds (memorisation is confirmed
by a brief audible signal).
A new memorisation operation cancels the
previous one.

Access
2

► Position yourself behind the vehicle by the
number plate and perform a “kicking” movement
in the “
OK” detection zone.
The “kicking” movement must be given forwards,
smoothly, not too fast and with a vertical
movement from low to high. Raise the foot
sufficiently and remove it immediately.
The taking into account of the “kicking”
movement is confirmed by the lighting of the
direction indicators.
"Sideward kicking" movements do not
work. If the “kicking” movement has not
been detected, wait at least 2 seconds before
repeating the movement.
Do not perform repetitive “kicking”
movements.
If the motorised tailgate has not started to open,
check that:
–

the function is activated.
–


the electronic key is on your person, outside
the vehicle in the rear recognition area.
–


the “kicking” movement was performed in the
detection zone, close enough to the bumper

.
–

the foot was removed from the bumper quickly
enough.
When the vehicle is locked, the request
to open the tailagte with this function
unlocks the vehicle, or only the tailgate if
selective unlocking is activated, prior to the
opening of the tailgate.
Closing the tailgate with the “Hands-Free
Tailgate Access” function enables you to lock
the vehicle.
Recommendations on the
hands-free function (Hands-
Free Tailgate Access)
If it does not work, check that the electronic key
is not exposed to a source of electromagnetic
interference (e.g. smartphone).
The function may be deactivated or affected if
there is rain or snow.
The function may not work correctly with a
prosthetic leg.
In some circumstances, the tailgate may open or
close by itself, particularly when:
–

hitching up or removing a trailer;
–


fitting or removing a bicycle carrier;
–


loading
or unloading bicycles on/from a bicycle
carrier;
–

depositing or lifting something behind the
vehicle;
–


an animal approaches the rear bumper;
–


washing the vehicle;
–


maintenance is performed on the vehicle;
–


accessing the spare wheel.
T

o avoid such operating problems, keep the
electronic key away from the recognition zone or
deactivate the hands-free function.
The installation of a towing device may disturb the detection system.
To avoid unintentionally opening the tailgate
while operating the towing device:
►

remove the electronic key from the
recognition zone, with the tailgate closed.
For more information on the T

owing device
with quickly detachable towball , refer to the
corresponding section.

Ease of use and comfort
3Interior rear view mirror
Equipped with an anti-dazzle system, which
darkens the mirror glass and reduces the
nuisance to the driver caused by the sun,
headlamps of other vehicles, etc.
Manual model
Day/night position

► Pull the lever to change to the anti-dazzle
"night” position.
►

Push the lever to change to the normal "day"
position.
Adjustment
►


Set the mirror to the normal “day” position.
Automatic "electrochrome" model

The electrochrome system uses a sensor that
detects the level of exterior brightness and that
coming from the rear of the vehicle, in order to
automatically and gradually switch between day
and night usage.
To ensure optimum visibility while manoeuvring, the mirror automatically
brightens when reverse gear is engaged.
The system is deactivated if the load in the
boot exceeds the height of the load space
cover or if the load space cover has items
placed on it.
Rear bench seat
Bench seat with fixed cushions and split folding
backrests (2/3-1/3) to adapt the boot load space.
Rear head restraints

They have two positions:
– A high position , for when the seat is in use:
►

Pull the head restraint fully up.
–

A low position , for stowing, when the seat is
not in use: ►

Press the lug
A to release the head
restraint and push it down.
The rear head restraints can be removed.
Removing a head restraint
► Release the backrest using control 1 .
► T ilt the backrest slightly forwards.
►

Pull the head restraint fully up.
►


Press the lug
A to release the head restraint
and remove it completely.
Refitting a head restraint
► Insert the head restraint rods into the guides
in the corresponding backrest.
►

Push the head restraint fully down.
►


Press the lug
A to release the head restraint
and push it down.
Never drive with passengers seated at
the rear when the head restraints are
removed; the head restraints should be in
place and in the high position.
The head restraint for the centre seat
and those for the outer seats are not
interchangeable.
Folding the backrests
Manoeuvring the backrests should only
be done when the vehicle is stationary.

forwards or backwards to obtain the desired
angle.
Heating and Ventilation
Air intake
The air circulating in the passenger compartment
is filtered and originates either from the
exterior, via the grille located at the base of the
windscreen, or from the inside in air recirculation
mode.
Controls
The controls are accessible through the Climate touch screen application and are
also grouped on the centre console panel.
Air distribution

1. Windscreen demisting/defrosting vents
2. Front side window demisting/defrosting vents
3. Adjustable and closable side air vents
4. Adjustable and closable central air vents
5. Air outlets to the front footwells
6. Air outlets to the rear footwells
7. Adjustable and closable air vents
Advice
Using the ventilation and air
conditioning system
►

T

o ensure that air is distributed evenly,
keep the external air intake grilles at the base
of the windscreen, the nozzles, the vents, the
air outlets and the air extractor in the boot
free from obstructions.
►

Do not cover the sunshine sensor located
on the dashboard; this sensor is used to
regulate the automatic air conditioning
system.
►


Operate the air conditioning system for at
least 5 to 10 minutes once or twice a month to
keep it in good working order

.
►

If the system does not produce cold air
,
switch it off and contact a CITROËN dealer or
a qualified workshop.
When towing a large load on a steep gradient
in high temperatures, switching off the air
conditioning increases the available engine
power, enhancing the towing capacity.
Avoid driving for too long with the ventilation off or with prolonged operation
of interior air recirculation. Risk of misting and
deterioration of the air quality!
If the interior temperature is very high
after the vehicle has stood for a long
time in the sunshine, air the passenger
compartment for a few moments.
Put the air flow control at a setting high
enough to quickly change the air in the
passenger compartment.
Condensation created by the air
conditioning results in a discharge of
water underneath the vehicle. This is perfectly
normal.
Servicing the ventilation and air
conditioning system
►

Ensure that the passenger compartment
filter is in good condition and have the filter
elements replaced regularly

.
We recommend using a composite passenger
compartment filter. Thanks to its special active
additive, this type of filter helps to purify the
air breathed by the occupants and keep the
passenger compartment clean (by reducing
allergic symptoms, unpleasant odours and
greasy deposits).

T

o ensure correct operation of the
air conditioning system, have it checked

Safety
Deactivation/reactivation is confirmed by
the lighting/switching off of this indicator
lamp on the instrument panel and the display of
a message.
The ASR system is reactivated automatically
every time the ignition is switched on or at
speeds over 31 mph (50
km/h).
Reactivation is manual below 31 mph (50 km/h).
Malfunction
In the event of a malfunction, this warning
lamp lights up on the instrument panel,
accompanied by the display of a message and
an audible signal.
Have it checked by a CITROËN dealer or a
qualified workshop.
ASR/DSC
These systems enhance safety during
normal driving, but should not encourage
the driver to take extra risks or drive at high
speed.
It is in conditions of reduced grip (rain, snow,
ice) that the risk of loss of grip increases. It
is therefore important for your safety to keep
these systems activated in all conditions, and
particularly in difficult conditions.
Correct operation of these systems depends
on compliance with the manufacturer's
recommendations relating to the wheels
(tyres and rims), braking and electronic
components, as well as the assembly and
repair procedures provided by CITROËN
dealers.
In order to ensure that these systems remain
effective in wintry conditions, the use of snow
or all-season tyres is recommended. All four
wheels must be fitted with tyres approved for
your vehicle.
All tyre specifications are listed on the
tyre/paint label. For more information
on Identification markings , refer to the
corresponding section.
Trailer stability assist (TSA)
When towing, this system reduces the risk of the
vehicle or trailer snaking.
Operation
The system is activated automatically when the
ignition is switched on.
The electronic stability control system (ESC)
must not have any faults.
The vehicle speed must be between 37 and 99
mph (60 and 160
km/h).
If the system detects that the trailer is
snaking, it applies the brakes to stabilise
the trailer and reduces engine power, if
necessary, to slow the vehicle (indicated by the
flashing of this warning lamp on the instrument
panel and the brake lamps coming on).
For information on weights and towed loads,
refer to the Engine technical data and towed
loads section or your vehicle’s registration
certificate.
To ensure safe driving with a Towing device,
refer to the corresponding section.
Malfunction
If a fault occurs, this warning lamp lights
up on the instrument panel, accompanied
by a message and an audible signal.
To continue towing a trailer, reduce speed and
drive carefully!
Have it checked by a CITROËN dealer or a
qualified workshop.
The trailer stability control system provides an extra safety feature under
normal driving conditions, when following the
recommendations for use of trailers and
current legislation in force in your country. It
must not encourage the driver to take extra
risks, such as using a trailer in unsuitable
conditions of operation (e.g.
excessive load,
exceeded nose weight, worn or under-inflated
tyres, faulty braking system) or driving at
excessive speed.
In certain cases, the system may not detect
trailer snaking, particularly with a light trailer.
When driving on slippery or poor surfaces, the
system may not be able to prevent sudden
trailer snaking.

Safety
5Lateral airbags
Use only approved seat covers
compatible with the deployment of these
airbags. For information on the range of seat
covers suitable for your vehicle, contact a
CITROËN dealer.
Do not fix or attach anything to the seat
backrests (e.g.
clothing) as this could cause
injuries to the chest or arm when the airbag is
deployed.
Do not sit with the upper part of the body any
nearer to the door than necessary.
The vehicle's front door panels include side
impact sensors.
A damaged door or any unauthorised or
incorrectly executed work (modification or
repair) on the front doors or their interior trim
could compromise the operation of these
sensors - risk of malfunction of the lateral
airbags!
All work must be carried out only by a
CITROËN dealer or a qualified workshop
Curtain airbags
Do not fix or attach anything to the roof,
as this could cause head injuries when the
curtain airbag is deployed.
Do not remove the grab handles installed on
the roof.
Active bonnet
(Depending on version.)

The active bonnet has been designed to
optimise the safety of pedestrians in the event of
collision with the front of the vehicle.
The pyrotechnic system is triggered at the
hinges of the bonnet to lift it, when the sensors
located at the front of the vehicle detect a
collision.
Deployment of the active bonnet is
accompanied by a slight discharge of
harmless smoke and a noise, due to the
activation of the pyrotechnic cartridge
incorporated in the system. The airbag
warning lamp comes on.
After triggering, do not try to open or close
the bonnet. Call a towing company or go to
the nearest CITROËN dealer or qualified
workshop, driving at a speed below 19 mph
(30

km/h).
Make sure that you adjust the height of the
driver's seat - risk of hindrance to visibility!
This equipment will only trigger once. If a second impact occurs (during the same
or a subsequent accident), the active bonnet
will not trigger.
After an accident or if the vehicle has been
stolen, have the system checked.
Do not tamper with the pyrotechnic systems
under the bonnet, close to the struts - risk of
explosion!
All work must be carried out only by a
CITROËN dealer or a qualified workshop
Malfunction
In the event of a malfunction, this warning
lamp lights up on the instrument panel,
accompanied by the display of a message and
an audible signal. You must contact a CITROËN
dealer or a qualified workshop to have the
system checked.
The active bonnet may not deploy in the event of
an impact.
Child seats
The legislation on carrying children is specific to each country. Refer to the
legislation in force in your country.
