(+)

Positive terminal.
This terminal has a quick-release clamp.
(-) Negative terminal.
As the battery's negative terminal is not
accessible, use the engine mounting.
Starting using another
battery
If the vehicle's battery is flat, the engine can be
started using a backup battery (either external or
from another vehicle) and jump leads or using a
battery booster.
Never start the engine by connecting a
battery charger.
Never use a 24
V or higher battery booster.
Check beforehand that the backup battery
has a nominal voltage of 12
V and a capacity
at least equal to that of the discharged
battery.
The two vehicles must not be in contact with
each other.
Switch off all electricity-consuming equipment
on both vehicles (audio system, wipers,
lighting, etc.).
Make sure that the jump leads are well away
from the engine’s moving parts (fan, belt,
etc.).
Do not disconnect the (+) terminal while the
engine is running.


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

Connect the red cable to the (+) terminal of
flat battery

A (at the metal elbow), then to the
(+) terminal of the backup battery
B or of the
booster.
►

Connect one end of the green or black cable
to the (-) terminal of the backup battery

B or of
the booster (or to an earth point on the assisting
vehicle).
►

Connect the other end of the green or black
cable to the earth point


C
.
►

Start the engine on the assisting vehicle and
leave it running for a few minutes.
►


Operate the starter on the broken down
vehicle and let the engine run.
If the engine does not start immediately

, switch
off the ignition and wait a few moments before
trying again.
►

W
ait for it to return to idle.
►

Disconnect the jump leads in reverse order.
► Refit the plastic cover to the (+) terminal, if
the vehicle has one.
►

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.
Automatic gearbox
Never try to start the engine by pushing
the vehicle.
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.

In the event of a breakdown
8Follow 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 earth point C


on the vehicle.
► 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.

Never try to charge a frozen battery - risk
of explosion!
If the battery has frozen, have it checked by a
CITROËN dealer or by a qualified workshop
who will verify that the internal components
have not been damaged and that the case
has not cracked, which would mean a risk of
toxic and corrosive acid leaking.
Some functions, including Stop & Start,
are not available if the battery is not
sufficiently charged.
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.

Frequently asked
questions
The following information groups together the answers to the most frequently asked questions
concerning your audio system. With the engine off, the audio system
switches off after a few minutes of use.
When the engine is switched off, the audio
system operating time depends on the state of
charge of the battery.
The switch-off is normal: the audio system
switches to economy mode and switches off to
avoid discharging the vehicle's battery.
►

Start the vehicle’
s engine to increase the
charge of the battery.
The message "the audio system is
overheated" is displayed onscreen.
To protect the installation if the ambient
temperature is too high, the audio system
switches to an automatic thermal protection
mode, in which the volume may be decreased or
the CD player stopped.
►
Switch the audio system off for a few minutes
to allow the system to cool.
Radio
There is a difference in sound quality
between the different audio sources (radio,
CD, etc.).
For optimal listening quality, the audio settings
(Volume, Bass, Treble, Ambience and Loudness)
can be adjusted to different audio sources,
resulting in audible differences when switching
between sources (radio, CD, etc.).
►

Check that the audio settings (V
olume, Bass,
Treble, Ambience and Loudness) are appropriate
to the sources being listened to. We recommend
setting the audio functions (Bass, Treble, Fr-Re
