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 their
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.
Important: with a motorised tailgate and its
"Hands-Free Tailgate Access" function, if a
towing device is fitted outside the CITROËN
dealer network, it is essential to visit a
CITROËN dealer or a qualified workshop
to recalibrate the detection system. Risk
of malfunction of the "Hands-Free Tailgate
Access" function.
Certain driving or manoeuvring aid functions
are automatically deactivated while an
approved towing system is in use.
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.
Complying with the maximum authorised
nose weight (towball weight) also includes
the use of accessories (bicycle carriers,
tow boxes, etc.).
Observe the legislation in force in the
country where you are driving.
Vehicle equipped with motorised
tailgate with "Hands-Free Tailgate
Access" function
To avoid unintentionally opening the tailgate
while operating the towing device:
–

Deactivate this function in advance in your
vehicle's configuration menu.
–


Or remove the electronic key from the
recognition zone, with the tailgate closed.
