Access to the battery
The battery is located under the loor on the front right
hand side (see “Battery compartment fuses”).
Emergency starting with a slave battery
A vehicle with a discharged battery can be started
with either a slave battery or the battery of another
vehicle.
A Discharged battery
B Slave battery
C Earth point on broken down vehicle.
It is essential to proceed strictly following the sequence
indicated.
Check that the emergency battery is correctly charged
up (12 volts). If you are using the battery on another
vehicle, stop the engine of the assisting vehicle. The
two vehicles must not come into direct contact with
each other.
Connect the cables in the order indicated in the
diagram. Make sure that the clamps are properly
secured (risk of sparks).
Start the engine of the assisting vehicle. Let the engine
run for about a minute at a slightly accelerated speed.
Never apply a lame or create sparks close
to the battery (explosive gas). The battery contains diluted sulphuric acid which is highly corrosive.
If ever you are handling the battery, protect your eyes a nd face.
In the event of any contact with the skin, rinse
immediately with copious amounts of fresh water.
Advice
Replace it with a battery of the
same type (voltage, amp rating).
Do not touch the cable clamps
during the procedure.
Do not lean over the batteries.
Disconnect the cables in the
reverse order to connection,
ensuring that they do not touch
each other. Start the engine of the assisted vehicle.
Note:
For any repair necessitating a disconnection
of the battery, it is essential to wait three minutes
after switching off the ignition and to avoid any action
that could prevent the vehicle’s electrical circuit from
changing to standby mode (such as opening and
closing doors, using the remote control etc.).

QUESTIONSANSWERSSOLUTIONS
The rec eption qualit y of the radio station being listened to gradually deteriorates.
The vehicle is too distant from the transmitter, or no transmitter is present in the geographical area you are passing th rough.
Activate the RDS function to allow the system to chec k whether a more power ful transmitter is to be found in the geographical area.
The environment (hills, high buildings, tunnels, underground car parks, etc.) is blocking reception, even in RDS mode.This phenomenon is normal and does not imply anythi ng wrong with the radio.
The aerial is absent or has been damaged (for example after going through a car wash or in an underground car park).Have the aerial checked by a CITROËN dealer.
When the engine is not running, the radio stops after a few minutes.
When the engine is switched off, the working time fo r the radio depends on the batter y charge. The interruption is nor mal: the radio goes into economy mode, cutting off in order to save the vehicle’s batter y.
You have to star t the engine so as to increase the bat-ter y charge.
T h e m e s s a g e “ t h e a u d i o s y s t e m i s o v e r h e a t i n g ” a p p e a r s o n t h e screen.
In order to protect the audio equipment in excessiv e ambient temperatures, the radio goes into an automatic thermic protection mode which results in a reduction in sound volume or stopping of the CD player.
Switch off the audio system for a few minutes in order to allow the system to cool down.
Why is one not informed in real time of a hold-up on the route even though the option for guidance by “traffi c info” is activated ?
When you star t up, the system takes a few minutes to c apture the traf fi c information via RDS-TMC.Wait for the traf fi c information to be safely received (pictogrammes displayed on the map) and make sure that you use the major ar terial roads to have “inform ed” navigation.
Only the major ar terial roads (motor ways and some d ual car-riageways) are featured in RDS-TMC traf fi c information).
It may happen that a hold-up is not repor ted by the tr af fi c info provider.
Why is a diversion not suggested when I have selected traf fi c info ?
Do not confuse the “traf fi c info” guidance option which can sug-gest a diversion (the “diver t” button appears in the w indow) with the menus “Display of traf fi c messages” or “Reading of traf fi c messages” which af fect only the display without recalculating the itinerar y (no “diver t” button in the window).
To have “informed” navigation with the detour proposi-tion, it is essential to activate the guidance option with “traf fi c info”.
