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 &.
Recommended windscreen washer fluid
• For warm weather: summer windscreen wash G 052 184 A 1. Dilution 1:100 (1 part concen-trate, 100 parts water) in the washer fluid reservoir.
• All-year washer fluid G 052 164 A2. Dilution in winter to -18°C (0°F) approx. 1 :2 (1 part concen-trate, 2 parts water), otherwise dilute one part con-centrate to four parts water (1 :4) in the washer fluid reservoir.
Capacities
The capacity of the washer fluid reservoir is ap-proximately 3. 7 litres or approximately 5.0 litres in vehicles with a headlight washer system.
A WARNING
Never mix coolant additive or other unsuita-ble additives into the windscreen washer flu-id. An oily film may otherwise be left on the windscreen or rear window which will restrict the field of vision.

Interior mirror .............. . 122
Exterior mirrors ............ . . .... 123
For safety reasons it is important that the driver po-sitions the exterior and interior mirrors correctly be-fore starting a journey '* &.
You can use the exterior mirrors and the interior mirror to observe traffic behind you and adjust driv-ing style accordingly. Looking in the exterior mir-rors and the interior mirror does not allow the driver to see the entre side and rear area of the vehicle. The area that cannot be seen is known as the blind spot. There may be objects and other road users in the blind spot.
Additional information and warnings:
• Exterior views '* page 5
• Changing gear '*page 260
• Braking, stopping and parking '*page 269
A WARNING (Continued)
• Use clean, clear water (not distilled water) with a washer fluid recommended by Volks-wagen Commercial Vehicles.
• A suitable anti-freeze agent should be added to the windscreen washer fluid If nec-essary.
CD
• Never mix other cleaning agents with the cleaning agents recommended by Volkswagen Commercial Vehicles. This can cause the ingre-dients to separate and block the windscreen washer jets.
• When refilling or changing service fluids, please ensure that the correct fluids are added through the correct openings. Incorrect service fluids can cause serious functional problems and engine damage.
Adjusting the exterior and interior mirrors while driving may cause the driver to become distracted. This can lead to accidents and se-rious Injuries.
• Exterior and interior mirrors should only be adjusted when the vehicle is stationary.
• When parking, changing lane, or perform-ing an overtaking or turning manoeuvre, al-ways pay careful attention to the area around the vehicle as objects and other road users may be located In the blind spot.
• Always ensure that the mirrors are posi-tioned correctly and that the rear view Is not restricted by ice, snow, condensation or any other objects.
A WARNING
Automatic anti-dazzle mirrors contain an electrolyte fluid which could leak If the mirror is broken.

Fig. 280 How to swap wheels.
.....-r'n First read and observe the introductory L-W! Information and safety warnings & on page 367.
The tyres are the most used and most underesti-mated parts of a vehicle. Tyres are very important as the narrow tyre surfaces are the only contact between the vehicle and the road.
The service life of tyres is dependent on tyre pres-sure, driving style handling and fitting.
The tyres and wheel rims are an essential part of the vehicle's design. The tyres and rims approved by Volkswagen Commercial Vehicles are specially matched to the characteristics of the vehicle and make a major contribution to good road holding and safe handling.
Avoiding damage to the tyres
• If you have to drive over a kerb or similar obsta-cle, drive slowly and at a right angle if possible.
• Inspect the tyres regularly for damage such as cuts. cracks or blisters.
• Remove foreign objects that are in the outer tyre tread and have not penetrated the Inner tyre 373.
• Always respond to any warning messages giv-en by the tyre monitoring system=:opage 318.
• Damaged or worn tyres must be replaced im-mediately =:o page 373.
• Regularly check the tyres for hidden damage =:-page 373.
368 Cleaning and maintenance
• Never exceed the top speed and load permitted for the tyres that are fitted =:o page 375.
• Protect the wheels, including the spare wheel, from contact with corrosive substances, including oils, lubricants, fuel and brake fluid =:o &.
• Replace missing dust caps immediately.
Tyres with directional tread pattern
Tyres with directional tread pattern have been de-veloped to roll in one direction only. An arrow on the tyre sidewall indicates the direction of rotation on tyres with directional tread =:o page 375. The di-rection of rotation must be adhered to. This is the only guarantee for optimum grip and helps to avoid aquaplaning, excessive noise and wear.
If, however, the tyre is fitted in the opposite direc-tion to the tread pattern, you must take more care when driving as the tyre is now no longer being used according to its designation. This is particu-larly important on wet roads. The tyres must be re-placed as quickly as possible or be fitted with the tread in the correct direction.
Rotating wheels front to rear
Regularly rotating the wheels as shown in the illus-tration =:o Fig. 280 is recommended to help ensure that tyres wear evenly. All the tyres will then last for about the same time.
Volkswagen Commercial Vehicles recommends having the wheels changed by a qualified work-shop.
Tyres that are older than 6 years
Tyres age through physical and chemical process-es that can impair their function. Tyres that are stored unused for an extended period will harden and become brittle more quickly than tyres which are in constant use.
Volkswagen Commercial Vehicles recommends re-placing tyres that are more than 6 years old with new tyres. This also applies for tyres, including the spare wheel, which appear to still be in good con-dition and whose tread depth has not yet reached the minimum value stipulated by legislation =:o &.
The age of a tyre can be determined from the man-ufacturing date, which Is a component of the tyre identification number (TIN) =:o page 375. .,..

Modern fabrics, such as dark denim, are often not colourfast. Light-coloured upholstery (soft materials or leather) is particularly sensitive to staining caused by these fabrics, even if you are careful. This is not caused by a fault in the upholstery, but by the non-colourfast nature of the garments.
Leaving stains, dirt and other deposits on the sur-face of vehicle components and cloth seat covers for a long time can make it difficult to clean and treat them. Stains, dirt and deposits may become impossible to remove, particularly if left for a long time.

General surface soiling of the upholstery and fabric trim can be cleaned with a commercially available foam cleaner.
If the upholstery and fabric trims are generally heavily soiled, consult a Volkswagen dealership for information on suitable cleaning methods before attempting any cleaning. If required, take the vehi-cle to a specialist cleaning company.
Treating stains
When treating stains, it may be necessary to clean the entire surface and not just the stain itself. This particularly applies if the surface shows general signs of wear. The cleaned area could otherwise be lighter than the surrounding area. If in doubt, consult a specialist cleaning company.
Type of stain Recommended cleaning method for seat cushions and upholstery
Water-based stains, e.g. cof-fee, fruit juice. -Moisten a sponge using water from a spray bottle and treat the stain by wiping in a circular motion. -Wipe clean with an absorbent, dry cloth.

A WARNING CD
If there is a fault in the airbag system, the air-bag may not trigger correctly, may not trigger at all or may trigger unexpectedly. This can cause severe or fatal injuries.
• The airbag system should be checked by a qualified workshop as soon as possible.
Q)
If the upholstery on electrically adjustable seats or on seat cushions containing airbag components gets wet, electric components and the vehicle electrics could be damaged.
• Wet seat cushions should be promptly dried out, and their system components checked, at a qualified workshop.
• Do not use steam cleaners as the steam pushes the soiling into the fabric and sets it.
390 Cleaning and maintenance
• High-pressure cleaners and coolant sprays can damage the upholstery.
Q)
• Brushes should be used on carpets and mats only. Other surfaces could be damaged by brushes.
• When washing paste or fine detergent solu-tions are applied with a damp cloth or sponge, visible edges may appear on the upholstery once it has dried. This can be due to substan-ces such as surfactants. These edges are usu-ally difficult or even Impossible to remove.
Q)
• Do not soak Alcantara® under any circum-stances.
• Do not use leather care products, solvents, wax polish, shoe cream, stain removers or sim-ilar products on Alcantara®.
• Do not use brushes if cleaning with liquids. This could damage the surface of the material.
