Driving
The system assesses the driver's level of alertness, fatigue and distraction by
identifying trajectory changes in relation to the
lane markings.
To do this, the system uses a camera, placed on
the upper part of the windscreen.
This system is particularly suited to fast roads
(speed higher than 43 mph (70
km/h)).
At a first alert level, the driver is warned by the
message "Be vigilant!", accompanied by an
audible signal.
After three first-level alerts, the system triggers
a further alert with the message " Dangerous
driving: take a break", accompanied by a more
pronounced audible signal.
In certain driving conditions (poor road
surface or strong winds), the system may
give alerts independent of the driver's level of
vigilance.
The following situations may interfere with the operation of the system or
prevent it from working:
–

lane markings absent, worn, hidden (snow
,
mud) or multiple (roadworks);
–

close to the vehicle ahead (lane markings
not detected);
–


roads that are narrow
, winding, etc.
Parking sensors
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .


This 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
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.
Adjusting the audible signalDepending on version, with
CITROËN Connect Nav, pressing
this button 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).

In the event of a breakdown
8– When using the vehicle mainly for short
journeys.
–

If the vehicle is to be taken off the road for
several weeks.
Contact a CITROËN dealer or a qualified
workshop.
To charge the vehicle's battery yourself, use only a charger compatible with
lead-acid batteries with a nominal voltage of
12

V.
Follow the instructions provided by the
manufacturer of the charger.
Never reverse polarities.
It is not necessary to disconnect the
battery.
►

Switch the ignition off.
►


Switch off all electrical consumers (audio
system, lighting, wipers, etc.).


► Switch off charger B before connecting
the cables to the battery, so as to avoid any
dangerous sparks.
► Ensure that the charger cables are in good
condition.
►

Lift the plastic cover on the (+) terminal, if the
vehicle has one.
►


Connect the cables of charger B

as follows:
•

the positive (+) red cable to the (+) terminal
of battery

A.
•

the negative (-) black cable to the (-) terminal
of battery

A.
►

At the end of the charging operation, switch
off charger B

before disconnecting the cables
from battery A.
If this label is present, use only a 12 V
charger to avoid causing irreversible
damage to the electrical components.
24V

Disconnecting the battery
In order to maintain an adequate state of
charge for starting the engine, we recommend
disconnecting the battery if the vehicle is to be
unused for an extended period.
Before disconnecting the battery:
►

Close all openings (doors, boot, windows,
roof). ►


Switch off all electricity-consuming devices
(audio system, wipers, lamps, etc.).
►

Switch off the ignition and wait for 4
minutes.
After accessing the battery, it is only necessary
to disconnect the (+) terminal.
Quick-release terminal clamp
Disconnecting the (+) terminal

► Depending on equipment, lift the plastic cover
on the (+) terminal.
►

Raise lever

A
fully to release clamp
B
.
►

Remove clamp

B
by lifting it off.

178
In the event of a breakdown
Reconnecting the (+) terminal

► Raise lever A fully.
► Refit open clamp B on the (+) terminal.
►

Push clamp
B fully down.
►

Lower lever

A
to lock clamp B.
►

Depending on equipment, lower the plastic
cover on the

(+) terminal.
Do not force the lever when pressing on
it, as if the clamp is not positioned
correctly, locking will then not be possible.
Start the procedure again.
Following reconnection
After reconnecting the battery, turn on the
ignition and wait 1 minute before starting the
engine, to enable the electronic systems to
initialise.
If minor problems nevertheless persist following
this operation, contact a CITROËN dealer or a
qualified workshop.
Referring to the relevant section, reinitialise
certain equipment:
–

Remote control key or electronic key
(depending on version).
–

Sunroof.
–

Electric windows.
–


Date and time.
–


Preset radio stations.
The Stop & Start system may not be operational during the trip following the
first engine start.
In this case, the system will only be available
again after a continuous period with the
vehicle immobilised, the duration of which
depends on the exterior temperature and the
state of charge of the battery (up to about 8
hours).
Towing the vehicle
General recommendations
Observe the legislation in force in the
country where you are driving.
Ensure that the weight of the towing vehicle is
higher than that of the towed vehicle.
The driver must remain at the wheel of the
towed vehicle and must have a valid driving
licence.
When towing a vehicle with all four wheels on
the ground, always use an approved towing
arm; rope and straps are prohibited.
The towing vehicle must move off gently.
When the vehicle is towed with its engine
off, there is no longer braking and steering
assistance.
A professional towing service must be
called if:
–

Broken down on a motorway or main road.
–


Not possible to put
the gearbox into neutral,
unlock the steering, or release the parking
brake.
–

Not possible to tow a vehicle with an
automatic gearbox, with the engine running.
–


T

owing with only two wheels on the ground.

to put the vehicle in free-wheeling mode.
For more information on Free-wheeling, refer
to the corresponding section.
Electric motor
An electric vehicle cannot under any
circumstances be used to tow another
vehicle.
However, it may be used, for example, to exit
a rut.
