towing Citroen DS4 2010.5 1.G User Guide

269Practical information
 On the front bumper, unclip the cover by pressing at the bottom.  Screw the towing eye in fully.  Install the towing bar.
 On the rear bumper, unclip the cover by pressing at the bottom.  Screw the towing eye in fully.  Install the towing bar.  Switch on the hazard warning lamps on both vehicles.  Move off gently, drive slowly and for a shor t distance.
Towing your vehicle Towing another vehicle
 Place the gear lever in neutral (position N on the electronic gearbox system). Failure to obser ve this special condition could result in damage to cer tain components (braking, transmission...) and the absence of braking assistance the next time the engine is star ted.
 Unlock the steering by turning the key in the ignition one notch and release the
parking brake.  Switch on the hazard warning lamps on both vehicles.
 Move off gently, drive slowly and for a shor t distance.

Towing a trailer, a caravan, etc.
Towbar suitable for the attachment of a trailer or caravan with additional lighting and signalling. Your vehicle is primarily designed for transpor ting people and luggage, but it may
also be used for towing a trailer.
We recommend the use of genuine CITROËN towbars and their harnesses that 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 trailer is not fitted by a CITROËN dealer, it is imperative that it is fitted using the vehicle's electrical pre-equipment, in accordance with the manufacturer's instructions.
Driving with a trailer places greater demands on the towing vehicle and the driver must take par ticular care.

271Practical information
The rear parking sensors will be deactivated automatically if a genuine
CITROËN towbar is used.
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 per formance. 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 incline depends on the gradient and the ambient temperature. In all cases, keep a check on the coolant temperature.
Braking
Towing a trailer increases the braking distance.
Tyres
 Check the tyre pressures of the towing vehicle and of the trailer, obser ving the recommended pressures.
Lighting
 Check the electrical lighting and signalling on the trailer.
 If the warning lamp and the STOP warning lamp come on, stop the vehicle and switch off
the engine as soon as possible.

* The weight of the braked trailer can be increased, within the GTW limit, if the GV W of the towin g vehicle is reduced by an equal amount. Warning: towing using a lightly loaded towing vehicle may have an adverse effect on its road holding.
The GTW and towed load values indicated are valid u p 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 m ph (100 km/h) (comply with the legislation in force in your country). High ambient temperatures may result in a reduction in the per formance of the vehicle to protect the engine; if the ambient temperature is above 37 °C, limit the towed load.
