Practical information

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.

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.
