Operating fault
If an automatic wiping malfunction occurs, the wipers will operate in intermittent mode. Have it checked by a CITROËN dealer. To retain the effectiveness of the "flat-blade" wiper blades, it is advisable to: - handle them with care, - clean them regularly using soapy water, - not use them to hold a sheet of cardboard against the windscreen, - replace them at the first signs of wear.
Do not cover the rain sensor, linked with the brightness sensor and located in the centre of the windscreen behind the rear view mirror. Switch off the automatic wiping when using an automatic car wash. In winter, it is advisable to wait until the
windscreen is completely clear of ice before activating the automatic wiping.
This position allows the wiper blades to be lifted for winter parking, cleaning or replacement without damaging the bonnet. In the minute following switching off of the ignition, any action on the wiper stalk positions the wipers ver tically. To park the wipers after this has been done,
switch on the ignition and operate the wiper stalk.

Rear parking sensors
System consisting of four proximity sensors, located in the rear bumper. This detects any obstacle (person, vehicle, tree, gate, etc.) behind the vehicle, except obstacles located just below the bumper.
An object, such as a stake, a roadworks cone or any other similar object may be detected at the beginning of the manoeuvre, but may no longer be detected when the vehicle comes close to it.
The parking sensor system cannot, in any circumstances, take the place of the vigilance and responsibility of the driver.
The system is activated as soon as reverse gear is engaged, accompanied by an audible signal. The proximity information is given by: - an audible signal, which becomes more
rapid as the vehicle approaches the obstacle. - a graphic on the multifunction screen, with
blocks which become increasingly closer to the vehicle.
Activation
When the distance between the rear of the vehicle and the obstacle is less than thir ty centimetres, the audible signal becomes continuous and the "Danger" symbol appears on the multifunction screen. On completion of the manoeuvre, when you exit reverse gear, the system becomes inactive.
Driving

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 assistance menu, refer to vehicle configuration 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.

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.
