116 I Before the journey
The uncoated area should not be covered either from the outside or the inside, nor should any stick-ers be applied to this area as this could cause a fault in the electronic components. A wARNING
Without adequate frost protection, the wash-er fluid can freeze on the windscreen and ob-scure your view of the road.
• In winter temperatures, the windscreen washer system should only be used when ad-equate frost protection has been added.
• Never use the windscreen washer system at winter temperatures before the windscreen has been heated by the ventilation system. This could lead to the anti-freeze mixture freezing on the windscreen and restrict the driver's vision. .,.

A WARNING
Worn or dirty wiper blades reduce visibility and increase the risk of accidents and severe injuries.
• Wiper blades should therefore always be changed if they are damaged or worn and no longer clean the windscreen properly.
Indicator lamp
Q)
In icy conditions, always check that the wiper blades are not frozen to the glass before using the wipers. When parking the vehicle in cold weather, it may be helpful to leave the front windscreen wipers in the service position 119.

The rain sensor will remain active after the ignition is switched off and back on again and will function again if the wiper lever is in position G) and if the vehicle is travelling at speeds higher than approxi-mately 16 km/h (10 mph).
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.
Checking and refilling the windscreen washer fluid level
Fig. 97 In the engine compartment: cap of washer fluid reservoir.
r--T'n First read and observe the introductory L-J,:,JJ information and safety warnings & on page 116.
The windscreen washer fluid level should be checked regularly and topped up as necessary.
120 I Before the journey
A filter can be found in the feed throat of the wash-er fluid reservoir. The filter keeps large dirt particles away from the washer jets when refilling. The filter should only be removed for cleaning. if the filter is damaged or cannot be found when refilling, these dirt particles will reach the system and will block the washer jets.
• Open the bonnet & 350.
• The washer fluid reservoir is identified by the $ symbol on the cap 97.
• Check whether there is enough windscreen washer fluid in the reservoir.
• To top up, mix clean water (not distilled water) with a washer fluid recommended by Volkswagen Commercial Vehicles Observe the dilution in-structions on the packaging.
• At low temperatures, add a special anti-freeze agent so that the fluid cannot freeze &.

A WARNING (Continued)
asthma or similar illnesses. Immediately en-sure that there is a sufficient supply of fresh air and get out of the vehicle. If this is not possible, open all of the windows and doors.
• If the electrolyte fluid gets into the eyes or onto the skin, immediately wash the area with plenty of water for at least 15 minutes and consult a doctor.
• If the electrolyte fluid gets onto shoes or clothing, wash immediately with plenty of wa-ter for at least 15 minutes. Clean shoes and clothes thoroughly before wearing them again.

A WARNING (Continued)
• Never try to stop a trailer from snaking by Increasing your speed.
A WARNING
Accidents and severe injuries can occur if the maximum permitted draw bar weight is ex-ceeded.
• Never exceed the specified values.
A WARNING
The start/stop system must always be switch-ed off manually when a trailer Is to be towed with towing brackets that were not retrofitted by Volkswagen Commercial Vehicles. Other-wise faults can occur In the brake system, possibly resulting In accidents and serious Injuries.
Technical requirements
,...-.('n First read and observe the introductory 1--J,:.U information and safety warnings & on page 139.
If the vehicle is supplied with a factory-fitted tow-ing bracket it will already have the necessary tech-nical modifications and meet the statutory require-ments for towing a trailer.
Only use a towing bracket which is approved for the gross weight of the trailer you want to tow as a retrofit solution. The towing bracket must be suit-able for the vehicle and trailer and be securely bol-ted to the vehicle's chassis. Only a towing bracket with a removable ball coupling should be used. Al-ways check and follow the data provided by the towing bracket manufacturer. Never install a weight-distributing or load-balancing towing brack-et on the vehicle.
Towing brackets fitted to the rear bumper
Never fit a towing bracket to the rear bumper or to its fastenings. The towing bracket must not prevent the rear bumper from functioning correctly. Do not
A WARNING (Continued)
• Always switch off the start/stop system manually If a trailer is attached to a towing bracket that was not retrofitted by Volkswa-gen Commercial Vehicles.
m Always switch off the anti-theft alarm when a L!J trailer is being hitched or unhitched 43. The tilt sensor could otherwise trigger an alarm unnecessarily.
m In new vehicles, do not tow a trailer during L!J the first 1,000 km 394.
m Volkswagen Commercial Vehicles recom-L!J mends removing the ball coupling before driving without a trailer. The level of damage sus-tained during a rear-end collision could be greater for vehicles with a fitted ball coupling than for those without.
m By law, the ball coupling must be removed if L!J a trailer is not being towed if it obscures the number plate.
m In some models, the towing bracket is re-L!J qui red for towing vehicles. For this reason, the towing bracket ball coupling should be stored in the vehicle at all times. carry out any alterations to the exhaust or brake systems. Check regularly to see if the towing bracket is fitted securely.
Engine cooling system
There is an increased load on the engine and the cooling system when towing a trailer. The cooling system must contain sufficient coolant and be able to cope with the extra load added by the trailer.
Trailer brake
If the trailer is equipped with its own brake system, comply with the relevant regulations. The trailer's brake system must never be connected to the ve-hicle brake system.
Emergency breakaway cable
Always use safety chains between your vehicle and the trailer 144.

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.
m If the engine is not running and electrical L.:!.J equipment is switched on in the trailer via the trailer socket, the vehicle battery will discharge. .,.
