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
