Towing a trailer
Towbar suitable for the attachment of a trailer
with additional lighting and signalling.
Your vehicle is primarily designed for
transporting people and luggage, but it may
also be used for towing a trailer.
We recommend the use of genuine
CITRoËN towbars and their harnesses
that have been tested and approved
from the design stage of your vehicle,
and that the fitting of the towbar is
entrusted to a CITRoËN dealer or a
qualified workshop.
If the towbar is not fitted by a CITRoËN
dealer, it is imperative that it is
fitted in accordance with the vehicle
manufacturer's instructions.
Driving with a trailer places greater demands
on the towing vehicle and the driver must take
particular care.
driving advice
distribution of loads
F 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. Above
1 000 metres, the maximum towed load must
be reduced by 10 % for every 1 000 metres of
altitude.
Refer to the "Technical Data" section for details
of the weights and towed loads which apply to
your vehicle.
Side wind
F Take into account the increased sensitivity
to side wind.
