Changing a bulb

For H7 type bulbs with lugs... take care to observe their correct installation so asto ensure the best lighting performance.


Risk of electrocution

Xenon bulbs (D5S-25W) must be replaced by a CITROËN dealer or aqualified workshop.

Practical information








Towing a trailer
We recommend the use of genuineCITROËN towbars and their harnessesthat 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 CITROËNdealer, it is imperative that it is fitted in accordance with the vehicle manufacturer's instructions. T
owbar suitable for the attachment of atrailer or installation of a bicycle carrier, with additional lighting and signalling.
Your vehicle is primaril
y designed for
transporting people and luggage, but it mayalso be used for towing a trailer.
Driving with a trailer places greater demands on the towing vehicle and the driver must take par ticular care.

Driving advice


Distribution of loads
)Distribute the load in the trailer so that theheaviest 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 b
y 10 % for every 1 000 metres of altitude.

Side wind
)Take into account the increased sensitivity
to side wind.
Cooling
To w i ng a trailer on a slope increases the
temperature of the coolant.
As the fan is electricall
y 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 incline
depends on the
gradient and the ambient
temperature.
In all cases, keep a check on the coolant
temperature.
) If the warning lamp and the
STOPwarning lamp come on, stop the vehicle and switch off
the engine as soon as possible.



Braking

To w i ng a trailer increases the braking distance.
To avoid overheating of the brakes on a long
mountain type of descent, the use of enginebraking is recommended.

Tyres
)
Check the tyre pressures of the towingvehicle and of the trailer, obser ving the
recommended pressures.



Lighting
)
Check the electrical lighting and signalling on the trailer.

R
efer to the "Technical data" section for detailsof the weights and towed loads which apply to your vehicle.


The rear parking sensors will be
deactivated automatically if a genuineCITROËN towbar is used.

When not towing a trailer, remove thequickly-detachable tow ball beforedriving.

322
Checks
Brake wear depends on the styleof driving, par ticularly in the case of vehicles used in town, over shor t
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 fluid level indicates that the brake
pads are worn.















Brake pads
For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.


Brake disc wear















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 lightbrake applications to dry and defrost the brakes.

Electric parking brake


For more information, refer to the "Electric parking brake - Operating faults" section. This s
ystem does not require any routine servicing. However, in theevent of a problem, have the systemchecked by a CITROËN dealer or a qualified workshop.
Manual gearbox

The gearbox does not require anymaintenance (no oil change).
Refer to the maintenance and
warranty guide for the details of
the level checking inter val for thiscomponent.
6-speed electronic gearbox
The gearbox does not require anymaintenance (no oil change).
Refer to the maintenance and
warranty guide for details of the checking interval for this component.
Automatic gearbox

The gearbox does not require anymaintenance (no oil change).
Refer to the maintenance and
warranty guide for details of the levelchecking interval for this component.
To avoid damaging the electrical units, the use of a high pressure washer in the engine compar tment is strictlyprohibited.

Technical data
* The kerb weight is equal to the unladen weight + driver (75 kg). **

The weight of the braked trailer can be increased, within the GTW limit, if the GVW of the towing vehicle is reduced by an equal amount; warning,
towing using a lightly loaded towing vehicle may have an adverse effect on its road holding.

Petrol weights and towed loads (in 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 (10 0 km/h) (comply with the legislation in force in your country).
High ambient temperatures may result in a reduction in the performance of the vehicle to protect the engine; if the ambient temperature is above 37 °C,
