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 &.

Using the refrigerator box
r--('n First read and observe the introductory information and safety warnings & on page 241.
The suspended basket in the refrigerator box is for cooling food. The temperature is lower under the basket than inside it. Closed containers or glass bottles are less likely to burst if they are stored in the basket rather than on the bottom of the refrig-erator box .& in Introduction on page 241.
The additional battery will discharge if the refriger-ator box is used for a long period while the engine is switched off and the 230-volt connection is not used.
Before the refrigerator box is used for the first time, it should be cleaned thoroughly using lukewarm water and a mild detergent.
Cleaning the refrigerator box
r--f'n First read and observe the introductory information and safety warnings & on page 241.
The refrigerator box works independently of the engine and the ignition. lt is fed exclusively by the additional battery. The refrigerator box is switched on and off and regulated using the central control panel.
As far as possible, keep food and drinks in the re-frigerator box in leak-proof containers. Do not over-fill the refrigerator box such that air circulation is impaired.
Cool the refrigerator box before placing food items and drinks in it. Items you wish to keep in the re-frigerator box should be removed from your house-hold fridge/freezer just before you start your jour-ney. When shopping during a journey, we recom-mend items from shop fridges/freezers be placed in the refrigerator box as quickly as possible. • Clean the refrigerator box using a household detergent before using it for the first time, as well as when it becomes soiled.
• To prevent mould and mildew from forming in the refrigerator box when it is not being used for long periods, place a folded dry towel between the box and its lid. Power supply in the vehicle, California

Fig. 226 Fuel consumption in litres per 100 km at two different outside temperatures.
r-1"'11 First read and observe the Introductory Information and safety warnings&. on page 278.
By adopting an economical driving style and antici-pating the traffic situation ahead, you can easily re-duce fuel consumption by 10-15%.
Cars use most fuel when accelerating. If you think ahead when driving, you will need to brake less and thus accelerate less. Wherever possible, let the car roll slowly to a stop, for instance when you can see that the next traffic lights are red.
Avoid short journeys
Directly after a cold start, the engine has a very high fuel consumption. The engine reaches its working temperature after a few kilometres, when fuel consumption will return to a normal level.
The engine and catalytic converter need to reach their proper working temperature in order to mini-mise fuel consumption and emissions. The out-side temperature is a key factor.
The different rates of fuel consumption for the same distance at both +20"C (+68"F) and at -10"C (+14"F) are shown in Fig. 226.
Therefore, avoid making too many short journeys and car share whenever possible.
Under the same conditions, the vehicle will use more fuel in winter than in summer.
280 I While dnvmg
Not only is it illegal in some countries to "warm up" the cold engine by running it while the vehicle is stationary, it is also technically unnecessary and a waste of fuel.
Adjust the tyre pressure
The correct tyre pressure reduces rolling resist-ance and therefore also fuel consumption.
Ensure that any new tyres purchased have opti-mum rolling resistance.
Use low viscosity engine oils
Fully synthetic low viscosity engine oils reduce fuel consumption. Low viscosity engine oils decrease frictional resistance in the engine and spread bet-ter and more quickly, especially for cold starts. They are especially effective In vehicles that make alotofshortjourneys.
Always ensure that the engine oil level is correct and that you keep to the service intervals (oil change intervals).
When buying engine oil, always make sure it com-plies with engine oil norms and has been approved by Volkswagen Commercial Vehicles.
Avoid unnecessary loads
Lighter vehicles are more economical and have lower environmental impact. An extra 100 kg, for example, can increase fuel consumption by up to 0.311100 km.
Remove all unnecessary objects and loads from the vehicle.
Remove any unnecessary special equipment and accessories
The more aerodynamic a vehicle, the lower its fuel consumption. Special equipment and accessories, such as roof carriers or bicycle carriers, make the vehicle less aerodynamic.
You should therefore remove any special equip-ment and luggage carriers that are not in use, es-pecially if you are going to be driving at high speeds.

CD
• Your vehicle is not suitable for use with bio-diesel and must not be filled up or driven with biodiesel. Failure to observe this point can re-sult in damage to the fuel system and engine.
• Some diesel manufacturers blend biodiesel with diesel fuel in compliance with European Standard 590 or an equivalent standard (in Ger-many). Use of this diesel is allowed and will not damage the engine or fuel system.
• The diesel engine has been developed for use with diesel only. For this reason, petrol, heating oil or other unsuitable fuels may not be used. These fuels can cause serious damage to the fuel system and engine.

SCR catalysts can be used to reduce emissions from diesel engines (SCR = Selective Catalytic Re-duction). The SCR catalyst uses Ad Blue® urea sol-ution to convert nitrogen oxides into nitrogen and water.
If the vehicle is equipped with this kind of emission control system for diesel vehicles, the filler neck for the Ad Blue® tank is located below the filler cap for the fuel tank.
The Ad Blue® level should be checked within the scope of the service work Service schedule.
Information on AdBiue®
The Ad Blue® consumption figures depend on the individual driving style, the system's operating tem-perature and the ambient temperature that the ve-hicle is operated in.
The vehicle is fitted with a separate tank for Ad Bl-ue®. The Ad Blue® tank holds approximately 13 li-tres. For technical reasons, the capacity may be slightly larger when refilling using refill bottles.
The Ad Blue® tank must never run empty. As of a remaining distance of approximately 2,400 km. the instrument cluster display will indicate that the
346 While drivmg
Ad Blue® must be refilled 348. If the re-maining range is 0 km, the engine cannot be star-ted anymore 347.
The Ad Blue® trademark is held by the German As-sociation of the Automobile Industry (VDA) in the USA, Germany, the European Union and other countries.
Additional information and warnings:
• Fuel 343
• Accessories, modifications, repairs and renewal of parts 394
A WARNING
If the AdBiue® level is too low, the vehicle cannot be restarted after the Ignition has been switched off. Starting with jump leads is also not possible.
• Refill AdBiue® at the latest when the re-maining distance reaches approximately 1,000 km.
• Never allow the Ad Blue® tank to run emp-ty.
A WARNING
Ad Blue® is an Irritant and corrosive fluid that can damage the skin, eyes and breathing passages upon contact.
