When towing
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 exterior
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, 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 and the headlamp beam
height of your vehicle.
For more information on Adjusting the
headlamp beam height , refer to the
corresponding section.
For more information on Weights
, refer
to the corresponding section.
The rear parking sensors will be
deactivated automatically to avoid the
audible signal if a genuine CITROËN
towbar is used.
If the exterior temperature is high, it
is recommended that the engine be
allowed to idle for 1 to 2 minutes after
the vehicle comes to a stop, to facilitate
its cooling.

Engines
Engine characteristics
The engine characteristics (capacity, maximum
power, maximum engine speed, fuel, CO
2
emissions, etc.) for your vehicle are given in
the registration document, as well as in sales
brochures.
These characteristics correspond to the
values type-approved on a test bed, under
conditions defined in European legislation
(Directive
1

999/99/EC).
For more information, contact a CITROËN
dealer or a qualified workshop.
Weights
Weights and towed loads
The maximum weights and towed loads for your
vehicle are given are given in the registration
document, as well as in sales brochures.
These values are also present on the
manufacturer's plate or label.
For more information, 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
apply up to a maximum altitude of
1
000 metres; the towed load mentioned
must be reduced by 10 % for every additional
1
000 metres.
The weight of the braked trailer can be
increased, within the GTW limit, on condition
that the GV W of the towing vehicle is reduced
by the same amount.
The recommended nose weight is the vertical
load on the towbar ball (removable with or
without tools).
GV W:

g
ross vehicle weight, the maximum
authorised vehicle weight.
GT W:

g
ross train weight, the maximum
authorised weight of vehicle plus trailer. High exterior temperatures may result
in a reduction in the per formance of
the vehicle to protect the engine; when
the exterior temperature is higher than
37
°C, limit the towed weight.
If the exterior temperature is high, it
is recommended that the engine be
allowed to idle for 1 to 2 minutes after
the vehicle comes to a stop, to facilitate
its cooling. Towing with a lightly loaded vehicle can
adversely affect roadholding.
Braking distances are increased when
towing a trailer.
Never exceed 60 mph (100 km/h) when
towing (comply with the legislation in
force in your country).
