Programming Operating faults
If there is an operating fault, when reverse gear is engaged this warning lamp comes on on the instrument panel, accompanied by an audible signal (shor t beep) and a message on the multifunction screen.
You can activate or deactivate the system by means of the multifunction screen configuration menu. The system state is memorised when switching off the ignition. For more information on access to the parking sensors menu, refer to "Configuration/ Vehicle parameters" in the "Multifunction screens" section corresponding to your screen.
The system will be deactivated automatically when towing a trailer or when a bicycle carrier is fitted (vehicle fitted with a towbar or bicycle carrier recommended by CITROËN).
In bad or wintry weather, ensure that the sensors are not covered with mud, frost or snow.

Failure to obser ve this special condition could result in damage to cer tain braking components and the absence of braking assistance the next time the engine is star ted.
When towing with all four wheels on the
ground, always use a towing bar. When towing with only two wheels on the ground, always use professional
lifting equipment. When towing with the engine off, there is no longer any assistance for braking or steering.

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. If the trailer is not fitted by a CITROËN dealer, it is imperative that it is fitted using the electrical pre-equipment installed at the rear of the vehicle, in accordance with the manufacturer's instructions.
Driving with a trailer subjects the towing vehicle to more significant stress and its driver must be par ticularly careful.

209Practical 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 towing load must be reduced by 10 % and so on for every 1 000 metres of altitude. Refer to the "Technical Data" section for details of the weights and towing 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 towing load on a long slope depends on the gradient and the ambient temperature. In all cases, pay attention to 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.
