227Practical information

We recommend the use of genuine
CITROËN towbars and their harnesses that have been tested and approvedfrom the design stage of your vehicle,and that the fitting of the towbar is
entrusted to a CITROËN dealer or aqualified workshop.
If the towbar is not fitted by a CITROËN dealer, it is imperative that it isfitted in accordance with the vehiclemanufacturer's instructions.
Driving advice
Distribution of loads
)
Distribute the load in the trailer so that the
heaviest items are as close as possible to
t
he 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 electrically controlled, its cooling capacity is not dependent on the engine speed. )
To lower the engine speed, reduce your speed.
)If the warning lamp and the STOP
warning 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.



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



Driving with a trailer places greater demands on the towing vehicle and the driver must take par ticular care.
The maximum towed load on a long incline depends on the gradient and the ambient
tem
perature.
In all cases, keep a check on the coolant
temperature.
