PRACTICAL INFORMATION

TOWING A TRAILER,
A CARAVAN, ETC.
We recommend the use of genu-
ine CITROËN towbars and their
harnesses that have been tested
and approved from the design
stage of your vehicle, and that
the fi tting of the towbar is en-
trusted to a CITROËN dealer or
a qualifi ed workshop.
If the towbar is not fi tted by a
CITROËN dealer, it is impera-
tive that it is fi tted in accordance
with the vehicle manufacturer's
instructions. The rear parking sensors will
be deactivated automatically if
a genuine CITROËN towbar is
used.

Towbar suitable for the attachment of a
trailer or caravan with additional lighting
and signalling.
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 de-
mands on the towing vehicle and the
driver must take particular care.


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 towed load
must be reduced by 10 % for every
1 000 metres of altitude.
Refer to the "Technical Data" section for
details of the weights and towed 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 towed load on a long in-
cline depends on the gradient and the
ambient temperature.
In all cases, keep a check on 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 braking
distance.
To avoid overheating of the brakes on a
long mountain type of descent, the use
of engine braking is recommended.

Tyres


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


Lighting


)
Check the electrical lighting and sig-
nalling on the trailer.

IDENTIFICATION MARKINGS

Various visible markings for the identifi -
cation of your vehicle.

A. Vehicle identifi cation number (VIN)
under the bonnet.
This number is engraved on the body-
work near the engine mounting.
B. Vehicle identifi cation number on
the dashboard.

This number is indicated on a self-
adhesive label which is visible through
the windscreen.
D. Tyre/paint label.

This label is affi xed to the driver's front
pillar.
The tyre pressures must be
checked when the tyres are cold,
at least once a month.
Low tyre pressures increase fuel
consumption.
C. Manufacturer's label.

The VIN is indicated on a self-destroying
label affi xed to the driver's centre pillar. It bears the following information:


- the tyre pressures, for unladen and
laden conditions,

- the wheel rim and tyre sizes,

- the brands of tyre recommended by
the manufacturer,

- the spare tyre infl ation pressure,

- the paint colour code.
Wheels which are fi tted with
225/40 R18 tyres cannot be fi t-
ted with snow chains. For more
information, contact a CITROËN
dealer or a qualifi ed workshop.
