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 must still be
fitted in accordance with the vehicle
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 places greater
demands on the towing vehicle and the
driver must take particular care.
Practical information

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 towed load must
be reduced by 10
% for every 1 000 metres of
altitude.
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 towed load on a long incline
depends on the gradient and the ambient
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f the warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine
as soon as possible.
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes on a long
mountain type of descent, the use of engine
braking is recommended.
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 electrical lighting and signalling on the trailer.
Refer to the "Technical data" section for
details of the weights and towed loads
which apply to your vehicle.
The rear parking sensors will be
deactivated automatically if a genuine
CITROËN towbar is used.

Practical information

Before each use
Check that the towball is correctly fitted by verifying the following points:
- t he towball is correctly locked in place (position A ),
-

t
he security key lock is on and the key removed; the locking wheel can no longer be
operated,
-

t
he towball must no longer move at all in its carrier; try to shake it by hand.
During use
Never unlock the device when a trailer or load carrier is fitted to the towball.
Never exceed the maximum authorised weight for the vehicle plus trailer (Gross Train
Weight - GTW).
After use
For journeys made without a trailer or load carrier, the trailer harness socket must be folded
away, the towball removed and the blanking plug inserted in the carrier. This measure
applies particularly if the towball could hinder visibility of the number plate or lighting.
Fitting the towball
Remove the protective plug from the carrier
and check the condition of the fixing system.
If necessary, clean the carrier with a brush or
clean cloth.
Take the towball from the storage bag.
Remove the protective cover from the ball and
the protective cap from the locking wheel.
Stow the plug, cover and cap in the storage
bag.
Check that the towball is unlocked (position B ).
If not, insert the key in the lock and turn the key
anti-clockwise to unlock the mechanism.

303
If the key cannot be turned or removed,
this means that the towball is not fitted
correctly; start the procedure again.
If one of the locking conditions is not
met, start the procedure again.
In all cases, if the marking remains
red, do not use the towbar and contact
a CITROËN dealer or a qualified
workshop.
Take the towball in both hands; insert the end
of the towball into the carrier by lifting it, then,
to ensure that it has correctly locked in place,
pull firmly down on the ball end of the towball.
The locking wheel automatically turns a quarter
of a turn anti-clockwise, making a perceptible
click; take care to keep your hands clear.
Check that the towball has correctly locked in
place (position A
).
Turn the key clockwise to lock the towball fixing
mechanism.
Always remove the key and keep it in a safe
place.

Be ready for the weight of the towball
(around 3.5 kg). Risk of injury!
Grasp the towball firmly with one hand; with
the other hand, press and turn the locking
wheel
clockwise as far as it will go.
Extract the towball downward. Refit the protective cover for the ball and the
protective cover for the locking wheel.
