Towing a trailer, a caravan...
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 following the manufacturer's
instructions.
Your vehicle is primarily designed for
transporting people and luggage, but it may
also be used for towing a trailer.
Driving with a trailer subjects the towing vehicle
to more significant stress and its driver must be
particularly careful.

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 per formance. Above
1
000 metres, the maximum towing load must
be reduced by 10
% of the GTW and so on for
every 1
000 metres of altitude.
Refer to the "Technical Data" section for details
of the weights and towing loads which apply to
your vehicle.
Side wind
F Take into account the increased sensitivity to side wind.
Cooling
Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towing load on a long slope
depends on the gradient and the outside
temperature.
In all cases, pay attention to the coolant
temperature.
F

I
f this message is displayed, stop your
vehicle as soon as it is safe to do so.
Braking
Towing a trailer increases the braking distance.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the lighting and signalling on the trailer.
If the message flashes slowly, wait for the
engine to cool before topping up the level, if
necessary.
If the message flashes rapidly, contact a
CITROËN dealer or a qualified workshop
without delay.

Fitting roof bars
The transverse roof bars are fitted to the longitudinal bars at the 8 fixing points masked by covers.
Using a small screwdriver, remove the 8 covers on the inner faces of the longitudinal bars.
The transverse bars are fitted directly to the roof of the vehicle, at the 4 anchorage points masked
by covers.
Slide the covers towards the front of the vehicle to remove them.
Retain the protective covers.
After removing the roof bars, the protective covers should be refitted:
F
i
nsert the fixing tongues into the apertures then slide the covers towards the rear of the vehicle. The body sill finishers should not be
used as a step when fitting roof bars.Use accessories recommended by
CITROËN and follow the accessory
manufacturer's fitting instructions.
Maximum authorised weight on the roof
bars, for a loading height not exceeding
40
cm (except bicycle carriers): 80 kg.
If the height exceeds 40 cm, adapt the
speed of the vehicle to the condition of
the road, to avoid damaging the roof
bars and the fixings on the roof.
Please refer to national legislation to
comply with the regulations regarding
the transportation of objects which are
longer than the vehicle.
For reasons of safety and to avoid damaging the roof, it is essential to use transverse bars that are
approved for your vehicle.

Brake wear depends on the style
of driving, particularly in the case
of vehicles used in town, over short
distances. It may be necessary to have
the condition of the brakes checked,
even between vehicle services.
Brake pads
For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.
Brake disc wearParking brake
If excessive travel or a loss of
effectiveness of this system is
noticed, the parking brake must be
checked, even between two services.
Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
units as important as those in the
braking system, CITROËN selects and
offers very specific products.
After washing the vehicle, dampness,
or in wintry conditions, ice can form
on the brake discs and pads: braking
efficiency may be reduced. Make light
brake applications to dry and defrost
the brakes.
Checking this system must be done by a
CITROËN dealer or a qualified workshop.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.

Petrol weights and towed loads (kg)
The values for maximum towed weights type
approved according to the sales zone (see the
tables on the following pages).
The exact values are given in your vehicle's
registration document as well as on the
manufacturer's plate.
They are also mentioned in sales brochures.
For more details, contact a CITROËN dealer or
a qualified workshop.The kerb weight is equal to the unladen
weight
+ driver (75 kg).The GTW and towed load values indicated are
valid up to a maximum altitude of 1 000 metres;
the towed load mentioned must be reduced
by 10 % for each additional 1 000 metres of
altitude.
The speed of a towing vehicle must not exceed
60 mph (100 km/h) (comply with the legislation
in force in your country).
High ambient temperatures may result in a
reduction in the per formance of the vehicle to
protect the engine; if the ambient temperature
is above 37 °C, limit the towed load.
The weight of the braked trailer can be
increased, within the GTW limit, if the
GV W of the towing vehicle is reduced
by an equal amount. Please note that
towing using a lightly loaded towing
vehicle may have an adverse effect
on its road holding
