OLUTION

Traf f ic A nnounc ements ( TA)
is displayed. I do not receive

any traffi c information or public

announcements.

The particular radio station is not in the regional traffi c

information network.

Change to a radio station that does broadcast

traffi c information.

The reception quality 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 through.

Activate the RDS function to allow the system to
check whether a more powerful transmitter is to
be found in the geographical area.

The environment (hills, high buildings, tunnels, under-
ground car parks, etc.) is blocking reception, even in
RDS mode.

This phenomenon is normal and does not imply
anything 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 for the
radio depends on the battery charge. The interruption is
normal.: the radio goes into economy mode, cutting off
in order to save the vehicle’s battery.

You have to start the engine so as to increase
the battery charge.

The message "the audio system
is overheating" appears on the
screen.

In order to protect the audio equipment in excessive
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.

Wait approximately 1 minute before operating the starter in order to allow the electronic systems to re-initialise.

After the battery has been disconnected for a lengthy period of time, it may be necessary to re-initialise the following
functions:

The anti-pinch on the windows.
The anti-pinch on the sun roof.
The multifunction display parameters (date, time, language, units of distance and of temperature).
The Radio stations.
The NaviDrive. See NaviDrive instructions.

STARTING THE ENGINE WITH AN ASSISTING
BATTERY

If the battery is discharged, it is possible to use either
a separate emergency battery or a battery on another
vehicle.
If you use the battery on another vehicle, stop the
engine on the latter. The two vehicles must not come
into direct contact with each other.
Check that the assisting battery has suffi cient voltage

(12 V).
Connect the cables according to the order indicated in

order

the diagram.

A Pole "+" on the vehicle being assisted (under the

red cover).

B Assisting battery.
C Pole "–" on the assisted vehicle (under the bonnet).
Check that the leads are well secured (risk of sparks).
Start the engine of the assisting vehicle. Let the engine
run for around 1 minute at a slightly accelerated idle.
Operate the starter on the vehicle being assisted.
It is essential to follow the indicated sequence
correctly.

Never approach with a fl ame or create sparks in the vicinity of the battery (explosive gas).
The battery contains dilute sulphuric acid which is highly corrosive.
When handling batteries, always protect your face and especially your eyes.
In the event of any contact with the skin, rinse immediately with copious amounts of fresh water.

ADVICE

Do not touch the leads during the operation.
Do not lean over the batteries.
Disconnect the cables in reverse order, making sure
they do not touch together.
