the style of driving, par-
ticularly in the case of ve-
hicles used in town, over
short distances. It may be
necessary to have the condition of
the brakes checked, even between
vehicle services.
Unless there is a leak in the circuit, a
drop in the brake fl uid level indicates
that the brake pads are worn.

TOWING A TRAILER,A CARAVAN, ETC.
Towbar suited to the attachment of a
trailer or caravan with additional sig-
nalling and lighting.
Your vehicle is primarily designed
for transporting people and luggage,
but it may also be used for towing a
trailer. If the trailer is not fi tted by a
CITROËN dealer, it is imper-
ative that it is fi tted using the
electrical pre-equipment installed at
the rear of the vehicle, in accordance
with the manufacturer's instructions.
Driving advice
Distribution of loads


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
towing load must be reduced by
10 % and so on for every 1 000 me-
tres of altitude.
Refer to the "Technical Data" section
for details of the weights and towing
loads which apply to your vehicle.
Side wind

 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.

 To lower the engine speed, reduce
your speed.
The maximum towing load on a long
slope depends on the gradient and
the ambient temperature.
In all cases, pay attention to the
coolant temperature.

 If 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 brak-
ing distance.
Tyres

 Check the tyre pressures of the
towing vehicle and of the trailer,
observing the recommended
pressures.
Lighting

 Check the electrical signalling on
the trailer.
The rear parking assistance will
be deactivated automatically if an
original CITROËN towbar is used.
We recommend the use of genuine
CITROËN towbars and their har-
nesses that have been tested and
approved from the design stage
of your vehicle, and that the fi t-
ting of the towbar is entrusted to a
CITROËN dealer. Driving with a trailer subjects the
towing vehicle to more signifi cant
stress and its driver must be particu-
larly careful.

ROOF BARS
The design of your vehicle requires
the use of roof bars and roof box-
es that are tested and approved by
CITROËN, for your safety and to avoid
damage to the roof and tailgate
Regardless of the type of loading
equipment to be transported on the
roof (roof box, bicycle carrier, ski
carrier...), it is imperative that you
add transverse roof bars.
Recommendations

 Distribute your load evenly, avoid-
ing overloading on one side.

 Arrange the heaviest part of the
load as close as possible to the
roof.

 Anchor the load securely and
signal if any part of it is over-
hanging.

 Drive gently, as the vehicle will
be more liable to the effects of
side winds (vehicle stability may
be altered).

 Remove the roof bars as soon
as they are no longer needed. Bicycle carrier
The installation of a bicycle carrier
on the tailgate of the 3-door model is
strictly prohibited.
Maximum load that can be dis-
tributed on the roof bars (for a
loading height not exceeding
40 cm; except bicycle carrier): 80 kg.
If the height exceeds 40 cm, adapt
your speed to the profi le of the road
to avoid damaging the roof bars
and the fi xings on the roof.
Please refer to national legislation
in order to comply with the regula-
tions concerning the transportation
of objects which are longer than
the vehicle.
* According to country.
VERY COLD CLIMATE SCREEN *
Removable device which prevents
the accumulation of snow at the ra-
diator cooling fan.
Fitting

 Offer up the very cold climate
screen to the front of the lower
section of the front bumper.

 Press on its periphery to clip its
fi xing clips one by one.
Removal

 Use a screwdriver as a lever to
unclip each fi xing clip in turn.
Do not forget to remove the very
cold climate screen:
- when the outside temperature exceeds 10 °C,
- when towing,
- at speeds higher than 75 mph (120 km/h).
