Driving
6This system detects and signals the proximity of
obstacles (e.g. pedestrian, vehicle, tree, barrier)
using sensors located in the bumper.
Rear parking sensors
► Engage reverse gear to start the system
(confirmed by an audible signal).
The system is switched off when reverse gear is
disengaged.
Audible assistance

The system signals the presence of obstacles
which are both within the sensors’ detection zone
and in the vehicle path defined by the direction of
the steering wheel.


Depending on version, in the example shown,
only the obstacles present in the shaded area
will be signalled by the audible assistance.
The proximity information is given by an
intermittent audible signal, the frequency of
which increases as the vehicle approaches the
obstacle.
When the distance between the vehicle and
the obstacle becomes less than about thirty
centimetres, the audible signal becomes
continuous.
The sound emitted by the speaker (right or
left) indicates the side on which the obstacle is
located.
Adjusting the audible signalPressing this button in the touch
screen opens the window for
adjusting the volume of the audible signal.
Visual assistance

This supplements the audible signal, without
taking account of the vehicle's trajectory, by
displaying bars on the screen that represent the
distance between the obstacle and the vehicle
(white: more distant, orange: close, red: very
close).
When the obstacle is very close, the "Danger"
symbol is displayed on the screen.
Front parking sensors
Supplementing the rear parking sensors, the
front parking sensors are triggered when an
obstacle is detected in front and the speed of the
vehicle is below 6 mph (10
km/h).
Front parking sensor operation is suspended if
the vehicle stops for more than three seconds in
forward gear, if an obstacle is no longer detected
or the vehicle speed exceeds 6
mph (10 km/h).
The sound emitted by the speaker (front or rear) locates the obstacle relative to
the vehicle, whether in front of or behind it on
its path.
Deactivation/Activation
It is configured in the ADAS touch screen
application.
If the function is deactivated, this indicator
lamp lights up on the instrument panel.
The system status is saved when the ignition is
switched off.

Practical information
Compatibility of fuels
Petrol fuels conforming to the EN228 standard
containing up to 5% and 10% ethanol
respectively.
The only petrol fuel additives authorised for use are those that meet the B715001
standard.
Travelling abroad
Certain fuels could damage your vehicle’s
engine.
In certain countries, the use of a particular
fuel may be required (specific octane rating,
specific trade name, etc.) to ensure correct
operation of the engine.
For all additional information, consult a dealer.
Refuelling
Fuel tank capacity: approximately 53 litres
(Petrol) or 40 litres (Rechargeable hybrid).
Reserve level: approximately 6 litres.
Low fuel level
When the low fuel level is reached, this
warning lamp lights up on the instrument
panel, accompanied by the display of a message
and an audible signal. When it first comes on,
about 6 litres of fuel remain.
Until sufficient fuel is added, this warning lamp
appears every time the ignition is switched on,
accompanied by the message and the audible
signal. When driving, this message and audible
signal are repeated with increasing frequency as
the fuel level drops towards 0.
You must refuel as soon as possible to avoid
running out of fuel.
A small arrow by the warning lamp indicates on which side of the vehicle the
fuel filler flap is located.
Stop & Start
Never refuel with the engine in STOP
mode; you must switch off the ignition.
Refuelling
Any addition of fuel must be in quantities of at
least 10 litres, in order to be registered by the
fuel gauge.
Opening the filler flap may create a noise caused
by an inrush of air. This vacuum is entirely
normal, resulting from the sealing of the fuel
system.
The filler cap is built into the filler
flap or must be
unscrewed (depending on version).
To refuel in complete safety:
►

Y
ou must switch off the engine.


► To open the filler flap, press the flap opening
button or press the rear edge of the filler flap
(depending on version).
Rechargeable hybrid vehicles
After pressing the button, it may take a
few minutes for the filler flap to open.
If the flap becomes stuck, press and hold the
button for more than 3
seconds.
►

T

ake care to select the pump that delivers the
correct fuel type for the vehicle's engine (see a
reminder label on the inside of the filler flap).


► Turn the filler cap to the left, remove it
and place it on its support on the filler flap
(depending on version).
►

Insert the filler nozzle and push it in as far as
possible before starting to refuel (to minimise the
risk of splashing).

Practical information
7If in doubt, during charging, do not remain
inside or near the vehicle, near the charging
cable or the charging unit, even for a short time.
Before charging
Depending on the context:
►

Have a professional check that the
electrical system to be used complies with
applicable standards and is compatible with
the vehicle.
►


Have a professional electrician install
a dedicated domestic power socket or
accelerated charging unit (W

allbox)
compatible with the vehicle.
Use the charging cable supplied with the
vehicle.
For more information, contact a CITROËN
dealer or a qualified workshop.
During charging
As a safety measure, the engine will
not start if the charging cable is plugged into
the connector on the vehicle. A warning is
displayed on the instrument panel.
While charging is in progress, unlocking the
vehicle will cause the charging to stop.
If no action is taken on one of the openings
(door or boot) or on the charging nozzle, the
vehicle will lock again after 30 seconds and
charging will resume automatically.
Never work under the bonnet:
–

Some areas remain very hot, even an hour
after charging ends - risk of burns!
– The fan may start at any time - risk of cuts
or strangulation!
After charging
Check that the charging flap is closed.
Do not leave the cable connected to the
domestic power socket - risk of short-circuit
or electrocution in the event of contact with or
