The alarm is triggered if anyone tries to open a
door, the boot or the bonnet, for example.
Interior volumetric monitoring
The system checks for any variation in volume in
the passenger compartment.
The alarm is triggered if anyone breaks a
window, enters the passenger compartment or
moves inside the vehicle.
Self-protection function
The system checks whether any of its
components are out of service.
The alarm is triggered if the battery, the central
control or the siren wiring is put out of service or

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 towable load
must be reduced by 10% per 1,000
metres of
altitude.
Use genuine towing devices and wiring
harnesses approved by CITROËN. We
recommend having them fitted by a CITROËN
dealer or a qualified workshop.
If not fitted by a CITROËN dealer, they must
still be fitted in accordance with the vehicle
manufacturer's instructions.
Certain driving or manoeuvring aid functions
are automatically deactivated while an
approved towing system is in use.
For more information about driving with a
towing device fitted to a trailer and associated
with the Trailer stability assist, refer to the
corresponding section.
Comply with the maximum authorised
towable weight, as indicated on your
vehicle's registration certificate, on the
manufacturer's label and in the Technical
data section of this guide.
If using accessories attached to the
towing device (e.g. bicycle carriers, tow
boxes):
–

Comply with the maximum authorised nose
weight.
–


Do not transport more than 3 bicycles.
When loading bicycles on to a bicycle carrier
over the towball, be sure to place the heaviest
bicycles as close as possible to the vehicle.
Observe the legislation in force in the
country where you are driving.
