The cooling system for the vehicle interior only works when the engine is running and the blower is switched on.
The air conditioning system operates most effec-tively with the windows and the sliding/tilting roof closed. However, if the vehicle has heated up after standing in the sun for some time, the air inside can be cooled more quickly by opening the win-dows and the sliding/tilting roof for a short time.
Settings for optimal road visibility
Switching the cooling system on not only reduces the temperature of the vehicle interior, but also the humidity. This improves comfort for the vehicle oc-cupants and prevents the windows from misting when the outside humidity is high.

Washing the vehicle
r-f'n First read and observe the introductory Information and safety warnings & on page 380.
The longer substances such as insects, bird drop-pings, resinous tree sap, road dirt, industrial de-posits, tar, soot or road salt and other corrosive materials remain on the vehicle, the more damage they do to the paintwork. High temperatures (for in-stance in strong sunlight) accelerate the corrosion process. The underside of the vehicle should also be cleaned thoroughly and regularly.
Car washes
Please observe the signs on the automatic car wash. Before using an automatic car wash take the usual precautions, such as closing all windows and folding in the exterior mirrors, in order to avoid damage to the vehicle. You must consult the car wash operator if there are special parts on your ve-hicle such as spoilers, roof luggage carrier systems or radio aerials ::.CD.
The paint is so hard-wearing that the car can nor-mally be washed without problems in an automatic car wash. However, the effect on the paint de-pends to a large extent on the design of the car wash. Volkswagen Commercial Vehicles recom-mends the use of car washes without brushes.
To remove any wax residue from the windows and to stop wipers rubbing, please note the following points ::.page 382, Cleaning windows and exterior mirrors.
Washing the car by hand
When washing by hand, first soften the dirt with plenty of water and rinse off as well as possible.
Then clean the vehicle with a soft sponge, a glove or a brush using only light pressure. Start with the roof and work from the top to the bottom. Use a shampoo for very stubborn dirt only.
The sponge or glove should be wrung out thor-oughly at regular intervals.
Clean the wheels, sill panels etc. last. Use a differ-ent sponge for this purpose.
A WARNING
Parts of the vehicle with sharp edges can cause Injury.
• Protect your hands and arms from cuts on sharp parts, for example when cleaning the underbody or the inside of the wheel hous-lngs.
A WARNING
After the car has been washed, the braking effect could set in later than normal and ex-tend the braking distance as the brake discs and brake pads will be wet, or iced up In win-ter.
• You can "dry and de-ice" the brakes by performing careful braking manoeuvres. Make sure that you do not endanger any oth-er road users or violate any legal regulations when doing so.
CD
• The water should be no warmer than +so•c (+140.FJ.
• Do not wash the vehicle in direct sunlight in order to avoid damage to the vehicle palntwork.
• Never clean with insect sponges, rough kitchen sponges or similar products as these can damage the surface.
• Never clean the headlights with a dry cloth or sponge. Always use a wet cloth or sponge. lt is best to use soapy water.
• Washing the vehicle In cold weather: if the vehicle is rinsed with a hose, do not direct the water at the lock cylinders or the gaps around the doors, boot, or bonnet. The locks and seals could freeze.
CD
Observe the following guidelines before driving the vehicle into an automatic car wash in order to avoid damage to the vehicle:
• Ensure that the gap between the guide rails In the car wash is sufficient for the vehicle track. If the track is too narrow your wheels and tyres will be damaged.
• Switch off the rain sensor before driving the vehicle Into an automatic car wash.
• Check that the car wash is tall and wide enough for your vehicle.
• Fold In the exterior mirrors. Electrically fold-Ing exterior mirrors must be moved electrically. Do not fold them in and out by hand.
• In order to prevent damage to the palntwork on the bonnet, fold the wipers back onto the windscreen after drying the wiper blades. Do not drop the wipers onto the glass.
• Lock the tailgate to prevent it from opening accidentally In the car wash.
