Driving
Adjusting the audible signal
(With MyCitroën Drive or MyCitroën
Drive Plus)
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).
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, in front or behind it.
Side parking sensors

Using four additional sensors located on the
sides of the bumpers, the system records the
position of obstacles during the manoeuvre and
indicates them when they are located alongside
the vehicle.
Only fixed obstacles are indicated
correctly. Moving obstacles detected at
the beginning of the manoeuvre may be
indicated mistakenly, while moving obstacles
that appear alongside the vehicle but were
not previously recorded will not be indicated.
Objects memorised during the
manoeuvre will no longer be stored after
switching off the ignition.

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.

►


Allow the engine to run for at least
30

minutes, with the vehicle stationary, so that
the battery reaches an adequate state of charge.
Driving immediately without having
reached a sufficient level of charge may
affect some of the vehicle's functions (e.g.
Stop & Start).
Charging the battery using a
battery charger
For optimum service life of the battery, it is
essential to maintain an adequate state of
charge.
In some circumstances, it may be necessary to
charge the battery:
– 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
12V
Disconnecting/reconnecting
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).
