2010.5 Citroen DS4 technical data

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.

Identifi cation markings
Various visible markings for the identification of yo ur vehicle.
A. Vehicle identification number (VIN) under the bonnet. This number is engraved on the bodywork near the engine mounting.
B. Vehicle identification 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 affixed to the driver's front pillar.
Wheels which are fitted with 225/40 R18 tyres cannot be fitted with snow chains. For more information, contact a CITROËN dealer or a qualified workshop.
Low tyre pressures increase fuel consumption.
The tyre pressures must be checked
when the tyres are cold, at least once a month.
C. Manufacturer's label. The VIN is indicated on a self-destroying label affixed 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 inflation pressure, - the paint colour code.
