PRACTICAL INFORMATION
12 V BATTERY
Procedure for starting the engine
using another battery or for charging
your fl at battery.


The Stop & Start battery does not
have to be disconnected for charging.







The presence of this label, in
particular with the Stop & Start
system, indicates the use of
a 12 V lead-acid battery with
special technology and specifi cation;
the involvement of a CITROËN deal-
er or a qualifi ed workshop is essential
when replacing or disconnecting the
battery.

After refi tting the battery, the Stop &
Start system will only be active after
a continuous period of immobilisa-
tion of the vehicle, a period which
depends on the climatic conditions
and the state of charge of the bat-
tery (up to about 8 hours).

*

or position P
for an automatic gearbox.


Access to the battery

Before doing any work
Immobilise the vehicle: ap-
ply the parking brake, put
the gearbox in neutral * , then switch
off the ignition.
Check that all electrical equipment
is switched off.


Check that the battery posts and
terminals are clean. If they are cov-
ered with sulphate (white or green
deposit), disconnect them and
clean them.

Batteries contain harmful
substances such as sul-
phuric acid and lead. They
must be disposed of in accordance
with regulations and must not, in
any circumstances, be discarded
with household waste.
Take used cell batteries and vehi-
cle batteries to an authorised col-
lection point.
The battery is located under the
bonnet.
For access to the (+) terminal:


)
Release the bonnet using the
interior lever, then the exterior
safety catch,

)
raise the bonnet and secure it
with its stay,

)
lift the plastic cover for access to
the (+) terminal.

PRACTICAL INFORMATION

Before disconnecting


)
Go to the battery.

)
Check that all of the openings -
doors, boot... - are closed but not
locked.

)
Wait at least four minutes after
switching off the ignition.
Charging


)
Disconnect the (+) terminal.

)
Follow the instructions on use
provided by the manufacturer of
the charger.

)
Connect the red cable of the
charger to the (+) post of the bat-
tery, then the black cable to the
(-) terminal.

)
Once charging is complete, dis-
connect the charger cables in re-
verse order.
The charging operation
must be carried out in a
well ventilated area and
well away from naked fl ames and
sources of sparks, so as to avoid
any risk of explosion and fi re.
Do not try to charge a frozen bat-
tery; the battery must fi rst be
thawed out to avoid any risk of ex-
plosion. If the battery has frozen,
before charging, have it checked
by a CITROËN dealer or a quali-
fi ed workshop, who will ensure that
the internal components have not
been damaged and that the casing
is not cracked, which would intro-
duce the risk of a leak of toxic and
corrosive acid.



Charging the battery using
a battery charger
If the battery of your vehicle is fl at
or prior to taking the vehicle out of
service for an extended period, you
can charge the battery using a bat-
tery charger.
For information on the specifi cation
of battery chargers compatible with
your battery, refer to a CITROËN
dealer or a qualifi ed workshop.
It is recommended that the battery
be disconnected if the vehicle is not
be used for more than a month.
Reinitialisation after
reconnection

After any reconnection of the bat-
tery, switch on the ignition and wait
at least one minute before starting,
to allow time for the initialisation of
the electronic systems.
By referring to the corresponding
sections, you should set or initialise
the following systems yourself:


- the date and time,

- the anti-pinch on the driver's
electric window and the sunroof.

- the panoramic sunroof blind,

- the multifunction screen set-
tings,

- the audio system or navigation
system settings,
Check that there no error message
or warning lamp comes on after
switching on the ignition.
However, if minor problems persist
after carrying out these operations,
contact a CITROËN dealer or a
qualifi ed workshop.

PRACTICAL INFORMATION

Towbar suitable for the attachment
of a trailer with additional lighting
and signalling.
Your vehicle is primarily designed
for transporting people and luggage,
but it may also be used for towing a
trailer.
We recommend the use of genuine
CITROËN towbars and their har-
nesses that have been tested and
approved from the design stage
of your vehicle, and that the fi t-
ting of the towbar is entrusted to
a CITROËN dealer or a qualifi ed
workshop.
If the towbar is not fi tted by a
CITROËN dealer, it is imperative
that it is fi tted in accordance with the
vehicle manufacturer's instructions.

Driving advice


Distribution of loads


)
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 ex-
ceeding it.
Air density decreases with altitude,
thus reducing engine performance.
Above 1 000 metres, the maximum
towed load must be reduced by 10 %
for every 1 000 metres of altitude.
Refer to the "Technical Data" section
for details of the weights and towed
loads which apply to your vehicle.

Side wind


)
Take into account the increased
sensitivity to side wind.


)
To lower the engine speed, re-
duce your speed.
The maximum towed load on a long
incline depends on the gradient and
the ambient temperature.
In all cases, keep a check on the
coolant temperature.


)
If the warning lamp and
the STOP
warning lamp
come on, stop the vehicle
and switch off the engine
as soon as possible.


Braking
Towing a trailer increases the brak-
ing distance.
To avoid overheating of the brakes
on a long mountain type of descent,
the use of engine braking is recom-
mended.

Tyres


)
Check the tyre pressures of the
towing vehicle and of the trailer,
observing the recommended
pressures.


Lighting


)
Check the electrical lighting and
signalling on the trailer.
The rear parking sensors will be
deactivated automatically if a gen-
uine CITROËN towbar is used.
Driving with a trailer places greater
demands on the towing vehicle and
the driver must take particular care.

Cooling
Towing a trailer on a slope increases
the temperature of the coolant.
As the fan is electrically controlled,
its cooling capacity is not dependent
on the engine speed.

There is a difference in sound quality betweenthe different audiosources (radio, CD...).
For optimum sound quality, the audio settings (Volume, Bass, Treble, Ambience, Loudness) can be adapted to the different sound sources,which may result in audible differences when changing source (radio,CD...).

Check that the audio settings (Volume, Bass, Treble, Ambience, Loudness) are adapted tothe sources listened to. It is advisable to setthe AUDIO functions (Bass, Treble, Front-Rear Balance, Left-Right Balance) to the middle position, select the musical ambience "None" and set the loudness correction to the "Active" position in CD mode or to the "Inactive" position in radio mode.

The CD is ejected automatically or is not played by the player.
The CD is inserted upside down, is unplayable, does not contain any audio data or contains an audio format which the player cannot play.
The CD is protected by an anti-pirating protectionsystem which is not recognised by the audio equipment.


- Check that the CD is inserted in the player the right way up.


- Check the condition of the CD: the CD cannot be played if it is too damaged.


- Check the content in the case of a recordedCD: consult the advice in the Audio section.


- The audio equipment's CD player does notplay DVDs.


- Due to inadequate quality, certain recordedCDs will not be played by the audio system.

The stored stations donot function (no sound, 87.5 Mhz is displayed...)
An incorrect waveband is selected. Press the BAND AST button to return to the waveband (AM, FM1, FM2, FMAST) on which thestations are stored.

The quality of receptionof the radio station listened to graduallydeteriorates or the stored stations do not function(no sound, 87.5 Mhz is displayed...).
The vehicle is too far from the transmitter used by the station listenedto or there is no transmitter in the geographical area through which the vehicle is travelling.
Activate the RDS function to enable the system to check whether there is a more powerful transmitter in the geographical area.
The environment (hills, buildings, tunnels, basement car parks...) block reception, including in RDS mode.
This phenomenon is normal and does not indicate a failure of the audio equipment.
The aerial is absent or has been damaged (for example when goingthrough a car wash or into an underground car park).
Have the aerial checked by a CITROËN dealer.
Sound cut-outs of 1 to2 seconds in radio mode.During this brief sound cut-out, the RDS searches for any frequency permitting better reception of the station.
Deactivate the RDS function if the phenomenon is too frequent and always on the same route.

With the engine off, the audio equipment switches off after a few minutes of use.
When the engine is switched off, the audio equipment operating timedepends on the battery charge.
The switch-off is normal: the audio equipment switches to economy mode and switches off to prevent discharging of the vehicle's battery.

Start the vehicle's engine to increase the batterycharge.

TRAFFIC INFO is selected. However,certain traffi c jams along the route are notindicated in real time.
On starting, it is several minutes before the system begins to receive thetraffi c information.
Wait until the traffi c information is being received correctly (displaying of the traffi c information symbols on the map).
In certain countries, only major routes (motorways, ...) are listed for thetraffi c information.
This phenomenon is normal. The system isdependent on the traffi c information available.
The time taken to calculate a route sometimes seems longer than usual.
The performance of the system may slow down temporarily if a CD isbeing copied onto the Jukebox at the same time as a route is being calculated.

Wait until the CD has been copied or stop the copying before starting the guidance function.
