Practical information
► Refit protective plug 2 to carrier 1.► Carefully stow the towball in its bag away from knocks and dirt.
Maintenance
Correct operation is only possible if the towball
and its carrier are kept clean.
Before cleaning the vehicle with a high-pressure
jet wash, the towball must be removed and the
protective plug fitted to the carrier.
Apply the label provided to a clearly visible area, close to the carrier or in the
boot.
Go to a CITROËN dealer or a qualified
workshop for any work on the towbar system.
Towing device
Load distribution► 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 exceeding it.
Air density decreases with altitude, thus reducing
engine performance. The maximum load which
can be towed must be reduced by 10% per
1,000 metres of altitude.
Use towing devices and their genuine
wiring harnesses approved by CITROËN.
It is recommended that the installation be
performed by a CITROËN dealer or a
qualified workshop.
If not fitted by a CITROËN dealer, it
must still be fitted in accordance with the
manufacturer's instructions.
Certain driving or manoeuvring aid functions
are automatically deactivated if an approved
towing system is used.
Observe the maximum authorised
towable weight, indicated on the vehicle's
registration certificate, the manufacturer's
label as well as in the Technical data section
of this guide.
Complying with the maximum authorised
nose weight (towball) also includes the
use of accessories (bicycle carriers, tow
boxes, etc.).
Observe the legislation in force in the
country where you are driving.
Load reduction mode
System which manages the use of certain
functions according to the level of charge
remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates certain
functions, such as air conditioning, heated rear
screen, etc.
The deactivated functions are reactivated
automatically as soon as conditions permit.
Energy economy mode
This system manages the duration of use of
certain functions, in order to conserve a sufficient
level of charge in the battery with the ignition off.
After switching off the engine, you can still
use functions such as the audio and telematic
system, the wipers and the dipped beam
headlamps or courtesy lamps, for a combined
duration of approximately 40 minutes.
Switching to this mode
A message appears in the instrument panel
screen indicating that the vehicle has switched to
economy mode and the active functions are put
on standby.
If a telephone call is being made at this
time, it will be maintained for around 10
minutes with the Bluetooth hands-free system
of your audio system.
Exiting the mode
These functions are automatically reactivated the
next time the vehicle is used.
To restore the use of these functions
immediately, start the engine and let it run:
– For less than 10 minutes, to use the equipment for approximately 5 minutes.
– For more than 10 minutes, to use the equipment for approximately 30 minutes.
Let the engine run for the specified duration to
ensure that the battery charge is sufficient.
To recharge the battery, avoid repeatedly or
continuously restarting the engine.
A flat battery prevents the engine from
starting.
For more information on the
12 V battery,
refer to the corresponding section.
Roof bars
For safety reasons and to avoid
damaging the roof, it is essential to use
the transverse bars approved for your vehicle.
Observe the fitting instructions and the
conditions of use in the guide supplied
with the roof bars.

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

174
Bluetooth® audio system
balance and Le-Ri balance) to the middle
position, setting the musical ambience to "None",
setting loudness correction to "Active" in CD
mode and "Inactive" in Radio mode.
The preset stations do not function (no
sound, 87.5 MHz is displayed, etc.).
The wrong waveband is selected.
► Press the BAND button to return to the waveband (FM, FM2, DAB, AM) on which the
stations are preset.
Traffic announcement (TA) is shown but I
receive no traffic information.
The radio station is not part of the regional traffic
information network.
► Tune to a radio station that broadcasts traffic information.
The reception quality of the tuned radio
station gradually deteriorates or the station
presets are inoperative (no sound, 87.5 MHz
is displayed, etc.).
The vehicle is too far from the selected station’s
transmitter, or no transmitter is present in the
geographical area.
► Activate the RDS function to allow the system to check for a more powerful transmitter in the
area.
The environment (hills, buildings, tunnels,
basement car parks, etc.) may block reception,
including in RDS mode.
This is a perfectly normal phenomenon, and is
not indicative of an audio system malfunction.The aerial is absent or has been damaged (for
example when going through an automatic car
wash or in an underground car park).
► Have the aerial checked by a dealer
.The sound intermittently cuts out for 1 or 2
seconds in radio mode.
During this brief sound cut-out, the RDS
searches for another frequency giving better
reception of the station.
► Switch off the RDS function if the phenomenon occurs too frequently and always
on the same route.
Media
The Bluetooth connection is cut.
The battery in the peripheral device may not be
sufficiently charged.
