Changes to the functioning of the rain sensor
Possible causes for faults and misinterpretations concerning the sensitive surface 96 of the rain sensor include:
• Damaged wiper blades: a film of water or smears caused by damaged wiper blades can in-crease the time the wipers are switched on, can shorten the length of the intervals between wipes or cause the wipers to run continuously.
• Insects: insects hitting the surface can cause the wipers to be activated.
• Salt deposits: in winter, salt deposits can cause the wipers to continue to wipe the windscreen when it is almost dry.
• Soiling: dry dust, wax, windscreen coatings (lo-tus effect) or detergent deposits (automatic car wash) can cause the rain sensor to become less sensitive and react too slowly or even not at all.
• Crack in the windscreen: when the windscreen is impacted by a stone, a wash cycle is triggered if the rain sensor is on. The rain sensor will then reg-
ister the reduction in sensitivity of the surface and adjust accordingly. The size of the crack could af-fect the way in which the sensor activates the wip-ers.
A WARNING
The rain sensor will not always detect every rain shower and activate the wipers.
• If necessary, switch on the wipers manual-ly if the water on the windscreen restricts the field of vision.
m At regular intervals, clean the sensitive sur-L!...J face of the rain sensor and check the wiper blades for damage 96 (arrow).
m We recommend that you use an alcohoi-W based glass cleaner to remove wax and pol-ish.

Trailer socket
A 13-pin trailer socket makes the electrical connec-tion between the towing vehicle and the trailer. When the engine is running, electrical consumers in the trailer are supplied with voltage (charging ca-ble) via the electrical connection (pin 10 of the trail-er socket). If required, the charging cable charges the caravan's battery.
When a trailer is electrically detected, electrical consumers in the trailer are supplied with voltage (permanent live) via the electrical connection (pin 9). Permanent live supplies a trailer's interior lighting for example. Electrical consumers such as a caravan refrigerator are supplied with voltage on-ly when the engine is running (pin 1 0).
To avoid overloading the electrical system, do not inter-connect the three earth wires (pins 3, 11 and 13).
If the trailer has a 7 -pin plug you will need to use a suitable adapter cable. Pin 10 (charging cable) is then without function.
Emergency breakaway cable
Always fasten the trailer's emergency breakaway cable properly to the towing vehicle. Leave enough slack in the emergency breakaway cable so that the vehicle can still drive around corners. However the emergency breakaway cable should not drag along the ground while you are driving.
Trailer rear lights
Ensure that the trailer lights work properly and meet legal requirements. Do not exceed the maxi-mum power consumption for the trailer 142.
Connection to the anti-theft alarm
The trailer is integrated in the anti-theft system if the following conditions are fulfilled:
• When the vehicle has a factory-fitted anti-theft alarm and a factory-fitted towing bracket.
• When the trailer is electrically connected to the towing vehicle via the trailer socket.
• When the vehicle and trailer electric systems are functional, fault-free and undamaged.
• When the vehicle is locked with the vehicle key and the anti-theft alarm is active.
When the vehicle is locked, the alarm will be trig-gered as soon as the electrical connection to the trailer is interrupted.
Always switch off the anti-theft alarm when a trailer is being hitched or unhitched. The tilt sensor could otherwise trigger an alarm unnecessarily.
Trailer with LED rear lights
For technical reasons, trailers with LED tail lights cannot be integrated into the anti-theft alarm sys-tem.
When the vehicle is locked, the alarm is not trig-gered as soon as the electrical connection to the trailer with LED rear lights is interrupted.
A WARNING
Any electrical cables that are not connected properly could cause a power surge to the trailer. This could cause faults tn the entire vehicle electronics system and also lead to accidents and serious Injuries.
• All work on the electric system should be carried out by a qualified workshop.
• Never connect the trailer's electrical sys-tem directly to the electrical connections of the tail lights or to other sources of electrici-ty.
CD
If you park the trailer using the support wheel or other trailer supports, disconnect the trailer from the vehicle. The vehicle could rock up and down if the load changes or if there is damage to the tyres. If this happens, a great deal of force will be exerted on the towing bracket and trailer, which could lead to damage to the vehi-cle and trailer.
CD
Maximum power consumption of the trailer should not be exceeded. Otherwise, the vehicle electrical system could be damaged.
m If there is a fault in the vehicle or trailer elec-L.:!.J trical systems or in the anti-theft alarm, have the systems checked by a qualified workshop.

ParkPilot
o:n Introduction
This chapter contains information on the following subjects:
ParkPilot only at rear . . 288 ParkPilot front and rear . . . 289
ParkPilot signal tones and displays . 290
The Park Pilot assists the driver when
parking and manoeuvring.
The ultrasound sensors in the bumpers transmit and receive ultrasound waves. The electronic sys-tem uses the ultrasound waves (i.e. transmission, reflection from the obstacle and reception) to cal-culate the distance between the bumper and the obstacle.
Additional information and warnings:
• Exterior views =:o page 5
• Braking, stopping and parking =:o page 269
• Reversing camera (Rear Assist) =:o page 291
• Cleaning and caring for the vehicle exterior =:.page 380
• Accessories, modifications, repairs and renewal of parts =:o page 394
• Radio or navigation system =:o Booklet Radio, provision for mobile telephone, infotainment sys-tem, navigation system
A WARNING
ParkPilot technology cannot overcome sys-tem-related vehicle limitations. The ParkPilot cannot replace the full concentration of the driver.
• Unintentional vehicle movements can cause serious injury.
• Always adapt your speed and driving style to suit visibility, weather, road and traffic con-ditions.
• Ultrasound sensors have blind spots in which obstacles and people cannot be detec-ted.
• Always check the area around the vehicle as the ultrasound sensors will not always de-tect infants, animals and objects.
A WARNING (Continued)
• Certain surfaces of objects and clothes cannot reflect the signals from the ultrasound sensors. The system is unable to detect these objects or people wearing this type of clothing, or they may be detected incorrectly.
• External sources of sound can affect the signals of the ultrasound sensors. This may prevent the system from recognising people or objects.
CD
Various factors can negatively Impact the Park-Pilot functions or lead to damage to the vehicle and objects in the area surrounding the vehi-cle.
• The ultrasound sensors may not always be able to detect objects such as trailer drawbars, thin rails, fences, posts, trees and open or opening boot lids. This can result in damage to your vehicle.
• If the ParkPilot has detected an obstacle and issued a warning, the obstacle may move out of the detection range of the ultrasound sensors as the vehicle approaches it, particu-larly if the object is very high or very low. These objects are no longer registered.
• The vehicle can sustain considerable dam-age if the warning given by the ParkPiiot is ig-nored.
• Ultrasound sensors can be displaced or damaged through Impacts, e.g. when parking.
• The ultrasound sensors must be kept clean and free of ice and snow, and must not be cov-ered up by stickers or other objects, as this will prevent the system from working properly.
• Repainting the ultrasound sensors can im-pair the function of the Park Pilot.
• The ultrasound sensors should only be sprayed briefly when cleaning with pressure hoses and steam cleaners. The steam/hose nozzle must always be kept more than 10 cm away from the ultrasound sensors.
• Sources of noise can lead to errors in the ParkPilot system, e.g. rough asphalt, cobble-stones, induction loops, building equipment, or interference from other vehicles.
