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.

When your vehicle's battery is discharged, the
engine can be started using a backup battery
(external or from another vehicle) and jump
leads or a battery booster.
Never try to 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 the electrical consumers on both
vehicles (audio system, wipers, lighting, etc.).
Make sure that the jump leads are not close
to moving parts of the engine (fan, belts, etc.).
Do not disconnect the (+) terminal while the
engine is running.


► Lift the plastic cover on the (+) terminal, if your vehicle has one.► Connect the red cable to the positive terminal (+) of flat battery A (at the metal elbow) then to
the positive terminal (+) of backup battery B or
the booster.
► Connect one end of the green or black cable to the negative terminal (-) of backup battery B
or the booster (or an earth point on the other
vehicle).
► Connect the other end of the green or black cable to earth point C on the broken down
vehicle.
► Start the engine of the vehicle with the good battery 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 straight away, switch
off the ignition and wait a few moments before
trying again.
► Wait until the engine returns to idle then disconnect the jump lead cables in the reverse
order.

Bluetooth® audio system
Bluetooth® audio system

The different functions and settings described vary according to the version
and configuration of your vehicle.
As a safety measure and because it requires sustained attention by the driver,
the pairing of a Bluetooth mobile telephone
with the Bluetooth hands-free system of your
audio system must be done with the vehicle
stationary and the ignition on.
Your audio system is coded in such a way that it will only operate in your
vehicle.
All work on the system must be carried out
exclusively by a dealer or qualified workshop,
to avoid any risk of electrocution, fire or
mechanical faults.
To avoid discharging the battery, the audio system may switch off after a few
minutes if the engine is not running.

RDS
The external environment (hills, buildings, tunnels, basement car parks,

mode. This is a normal effect of the way in
which radio waves are transmitted and does
not indicate any failure of the audio
equipment.
If RDS is not available, the RDS symbol
appears struck out in the screen.
The RDS, if activated, enables you to continue listening to the same station by
automatic retuning to alternative frequencies.
However, in certain conditions, coverage of
an RDS station may not be assured
throughout the entire country as radio stations
do not cover 100% of the territory. This
explains the loss of reception of the station
during a journey.
