Driving
6This 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
Operation
► When approaching a parking area, reduce
the speed of your vehicle to 19 mph (30 km/h)
or less.
Activating the function
With MyCitroën Play or MyCitroën Drive
The function is activated in the Vehicle/ Driving touch screen menu.
Select "Park Assist".
With MyCitroën Drive Plus
► In the ADAS touch screen application,

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 is suspended at
higher speeds. The function is automatically
deactivated if 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 touch screen, it will be
automatically reactivated when the system is

surroundings during the manoeuvre.
During the manoeuvre
The system controls the vehicle’s steering. It
gives instructions on the manoeuvring direction
when starting "parallel" entry and exit parking
manoeuvres, and for all "bay" entry manoeuvres.
With MyCitroën Play or MyCitroën Drive
These instructions are displayed as a symbol
accompanied by a message:
"Move backwards".
“Go forwards".
The manoeuvring status is indicated by these
symbols:
Manoeuvre in progress (green).
Manoeuvre cancelled or finished (red).
The arrows indicate that the driver must
take back control of the vehicle.
With MyCitroën Drive Plus
These instructions are displayed as a symbol
accompanied by a message:

The hands on the steering wheel indicate
that the driver must take back control of the
vehicle.
The maximum speed during manoeuvres is
indicated by this symbol:
53 mph or 5 km/h (for parking space entry,
the manoeuvre is possible up to 5 mph or
7

km/h)
During manoeuvring phases, the steering
wheel performs rapid turns: do not hold
the steering wheel or put your hands between
the spokes of the steering wheel. Watch out
for any objects that could interfere with the
manoeuvre (loose clothing, scarf, tie, etc.).
Risk of injury!
It is the driver's responsibility to constantly

Practical information
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!
To clean instrument panels, touch screens
or other displays, wipe gently with a soft,
dry cloth. Do not use products (e.g. alcohol,
disinfectant) or soapy water directly on these
surfaces - risk of damage!
Bodywork
High-gloss paint
Do not use abrasive products, solvents,
petrol or oil to clean the bodywork.
Never use an abrasive sponge to clean
stubborn stains - risk of scratching the
paintwork!
Do not apply polish in strong sunshine, or to
plastic or rubber parts.
Use a soft cloth and soapy water or a pH
neutral product.
Gently wipe the bodywork with a clean
microfibre cloth.
Apply polish with the vehicle clean and dry.
Comply with the instructions for use stated on
the product.
Decals
(Depending on version)
Do not use a high-pressure washer to
clean the vehicle - risk of damaging or
detaching the decals!
Use a high-flow hose (temperature
between 25°C and 40°C).
Place the jet of water perpendicular to the
surface to be cleaned.
Rinse the vehicle with demineralised water.
Textile
The dashboard, door panels and seats may
contain parts made of textile material.
Maintenance
Do not use aggressive cleaning products
(e.g. alcohol, solvent or ammonia).
Do not use steam-cleaning systems - risk of
affecting the adhesion of the fabrics!
Remove dust from the textile parts
regularly with a dry cloth, soft brush or
vacuum cleaner
.
Rub down the
textile parts once per year with
a clean, damp cloth. After leaving overnight to
dry, brush with a soft-bristled brush.
