Advice
Remote control
The remote control is a sensitive, high-
frequency device; avoid handling it in your
pocket, due to the risk of unintentionally
unlocking the vehicle.
Avoid pressing the remote control buttons
while out of range of the vehicle, due to
the risk of rendering the remote control
inoperative. It would then be necessary to
reset it.
The remote control does not work when the key is in the ignition switch, even when the
ignition is switched off.
Anti-theft protection
Do not modify the electronic vehicle
immobiliser, as this might result in
malfunctions.
For vehicles with a key ignition switch,
remember to remove the key and turn the
steering wheel to engage the steering lock.
Locking the vehicle
Driving with the doors locked could make
it more difficult for the emergency services to
enter the vehicle in an emergency.
As a safety precaution, remove the key from
the ignition or take the electronic key with you
when leaving the vehicle, even for a short
time.
Purchasing a second-hand vehicle
Have the key codes memorised by a
CITROËN dealer, to ensure that the keys in
your possession are the only ones able to
start the vehicle.
In order to preserve the battery in the
electronic key and the vehicle's battery:
– All of the "hands-free" functions go into extended standby after 21 days of non-use.
To restore these functions, unlock the vehicle
using the remote control and start the engine.
Electrical interference
The electronic key may not operate if
close to certain electronic devices: telephone
(switched on or on standby), laptop computer,
strong magnetic fields, etc.

This system:– warns the driver that their vehicle is at risk of collision with the vehicle in front or a pedestrian.– reduces the vehicle's speed to avoid a collision or limit its severity.
This system is comprised of three functions:
– Collision Risk Alert.
– Intelligent emergency braking assistance.– Active Safety Brake (automatic emergency braking).

The vehicle has a camera located at the top of
the windscreen.
This system does not avoid the need for
vigilance on the part of the driver.
This system is designed to assist the driver
and improve road safety.
It is the driver's responsibility to continuously
monitor the state of the traffic, observing the
driving regulations.
As soon as the system detects a potential obstacle, it prepares the braking
circuit in case automatic braking is needed.
This may cause a slight noise and a slight
sensation of deceleration.
Deactivation / Activation
By default, the system is automatically activated
at every engine start-up.
The system can be deactivated or activated via
the vehicle settings menu.
Deactivation of the system is signalled by the illumination of this indicator lamp,
accompanied by the display of a message.
Without audio system
► In the "DRIVE ASSIST" menu on the
instrument panel display, activate/deactivate
"COLLISION ALT" (Automatic emergency
braking).
With audio system
► In the "Personalisation-
configuration " menu, activate/deactivate
"Auto. emergency braking".
With touch screen
► In the Driving / Vehicle menu, select
the "Vehicle settings" tab, then
"Security" and activate/deactivate " Automatic
emergency braking".
Operating conditions and
limits
ESC system in working order.

Driving
6Using sensors located in the bumper, this
system signals the proximity of obstacles
(e.g. pedestrian, vehicle, tree, barrier) present in their field of detection.
Rear parking sensors
The system is switched on by engaging reverse
gear, which is confirmed by an audible signal.
The system is switched off when disengaging
reverse gear.
Audible assistance

The system signals the presence of obstacles
within the sensors’ detection zone.
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.
Visual assistance


This supplements the audible signal 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
In addition to the rear parking sensors, the front
parking sensors are triggered when an obstacle
is detected in front and the speed of the vehicle
is still below 6 mph (10 km/h).
The front parking sensors are interrupted if the
vehicle stops for more than three seconds in
forward gear, if no further obstacles are detected
or when the speed of the vehicle exceeds 6 mph
(10 km/h).
The sound emitted by the speaker (front or rear) indicates whether the obstacle is
in front or behind.
Deactivation / Activation
With / Without audio system


► To deactivate or activate the system, press this button.
The indicator lamp is lit when the system is
deactivated.
With touch screen
► In the Driving / Vehicle menu, select
“Driving functions ”, then “Parking
sensors”.
The state of the system stays in the memory
when the ignition is switched off.
The rear parking sensors system will be deactivated automatically if a trailer or
bicycle carrier is connected to a towing device
installed in accordance with the
manufacturer's recommendations.

Driving
6obstacles that are very low (pavements, studs,
etc.) or very thin (trees, posts, wire fences, etc.).
– Certain obstacles located in the sensors’ blind spots may not be detected or may no longer be
detected during the manoeuvre.
– Certain materials (fabrics) absorb sound waves: pedestrians may not be detected.– A front or rear impact to the vehicle can upset the sensors’ settings, which is not always
detected by the system: distance measurements
may be distorted.
– If the boot is heavily loaded, the vehicle may tilt, affecting distance measurements.
The vehicle's sensors and camera(s) may be
impaired by:
– accumulated snow or fallen leaves on the road,– adverse weather conditions (heavy rain, thick fog, falling snow),– noise interference from noisy vehicles and machinery (lorries, pneumatic drills, etc.).
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
If the parking sensor malfunction occurs during use, indicated by this warning lamp
coming on, 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.

Apply the label provided to a clearly visible area, close to the carrier or in the
boot.
Go to a CITROËN dealer or a qualified
workshop for any work on the towbar system.
Towing device
Load distribution► 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 load which
can be towed must be reduced by 10% per
1,000 metres of altitude.
Use towing devices and their genuine
wiring harnesses approved by CITROËN.
It is recommended that the installation be
performed by a CITROËN dealer or a
qualified workshop.
If not fitted by a CITROËN dealer, it
must still be fitted in accordance with the
manufacturer's instructions.
Certain driving or manoeuvring aid functions
are automatically deactivated if an approved
towing system is used.
Observe the maximum authorised
towable weight, indicated on the vehicle's
registration certificate, the manufacturer's
label as well as in the Technical data section
of this guide.
Complying with the maximum authorised
nose weight (towball) also includes the
use of accessories (bicycle carriers, tow
boxes, etc.).
Observe the legislation in force in the
country where you are driving.
Load reduction mode
System which manages the use of certain
functions according to the level of charge
remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates certain
functions, such as air conditioning, heated rear
screen, etc.
The deactivated functions are reactivated
automatically as soon as conditions permit.
Energy economy mode
This system manages the duration of use of
certain functions, in order to conserve a sufficient
level of charge in the battery with the ignition off.
After switching off the engine, you can still
use functions such as the audio and telematic
system, the wipers and the dipped beam
headlamps or courtesy lamps, for a combined
duration of approximately 40 minutes.
Switching to this mode
A message appears in the instrument panel
screen indicating that the vehicle has switched to
economy mode and the active functions are put
on standby.
If a telephone call is being made at this
time, it will be maintained for around 10
minutes with the Bluetooth hands-free system
of your audio system.
Exiting the mode
These functions are automatically reactivated the
next time the vehicle is used.
To restore the use of these functions
immediately, start the engine and let it run:
– For less than 10 minutes, to use the equipment for approximately 5 minutes.
– For more than 10 minutes, to use the equipment for approximately 30 minutes.
Let the engine run for the specified duration to
ensure that the battery charge is sufficient.
To recharge the battery, avoid repeatedly or
continuously restarting the engine.
A flat battery prevents the engine from
starting.
