r-111 First read and observe the Introductory l-Jo=,.lJ Information and safety warnings & on page 362.
The electrolyte level of the vehicle battery should be checked regularly in high-mileage vehicles, in hot countries and in older vehicle batteries. The vehicle battery is otherwise maintenance-free.
364 I Cleaning and maintenance
Vehicles with a starUstop system (=>page 283) are fitted with special vehicle batteries. The acid level of these vehicle batteries cannot be checked for technical reasons.
Preparation
• Preparing the vehicle for working in the engine compartment =>page 350.
• Open the bonnet &::. =>page 350.
Opening the battery cover
Fold the sleeve away to one side =>Fig. 279.
Checking the electrolyte level
• Ensure that enough light is available for you to see the colours clearly. Never use naked flames or glowing matter (e.g. cigarettes) as a light source.
• The colour display in the round window on the top side of the vehicle battery will change accord-ing to the electrolyte level.

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. Vehicle care and maintenance 381

Additional functions that are contractually agreed with the customer, e.g. vehicle positioning in an emergency, allow certain vehicle data to be trans-mitted from the vehicle.
Event data recorder
The vehicle is not fitted with an event data record-er.
Event data recorders temporarily store vehicle in-formation. This provides precise information in the event of an accident. In vehicles with an airbag system, data that might be relevant in the event of an accident can be stored, e.g. impact speed, belt buckle status, seat positions and trigger speed. The scope of the data is manufacturer-specific.
An event data recorder may only be fitted if the owner has approved the procedure. This is cov-ered by legislation in some countries.
Reprogramming control units
All data for the control of components are stored in the control units. Some convenience functions, such as lane change flash, single door unlocking and displays, can be reprogrammed using special workshop equipment. If this is the case, the de-scriptions in your vehicle wallet will no longer cor-respond with the original functions. Volkswagen Commercial Vehicles recommends that any re-programming should be confirmed in the service schedule under "Workshop comments".
Information about possible reprogramming can be obtained from the Volkswagen dealership.
Reading the vehicle's event memory
There is a diagnostic interface for reading the event memories in the vehicle interior &. Data relating to the function and status of the electronic control units are stored in the event memory. Addi-tional information on the stored data is available from qualified workshops.
The diagnosis interface is located in the footwell on the driver side behind a cover next to the lever for opening the bonnet.
The event memory should only be read and reset by a qualified workshop.
After a fault has been rectified, the information in the memory pertaining to the fault is deleted. Other memory content is overwritten on an on-going ba-sis.
A WARNING
Incorrect use of the diagnostic Interface can cause faults, which can result in accidents and serious injuries.
• Never read the event memory using the di-agnostic Interface yourself.
• The diagnostic Interface should only be read by a qualified workshop. Using a mobile telephone in the vehicle without a connection to the
external aerial
,...--.m First read and observe the introductory L--I=>U information and safety warnings & on page 394.
Both during telephone calls and in standby mode, mobile telephones transmit and receive radio waves, which may also be termed "high-frequency energy". Current scientific literature warns us that radio waves can be harmful to human beings if they exceed certain limits. Government bodies and international committees have introduced threshold values and guidelines to ensure that electromag-netic radiation produced by mobile telephones does not pose a hazard to health. However, there is no proven scientific evidence that demonstrates that cordless telephones are absolutely safe.
For this reason, some experts are calling for more precautions to be taken in the use of mobile tele-phones, by taking steps to reduce the level of per-sonal exposure to electromagnetic radiation.
If a mobile telephone that is not connected to the vehicle's external aerial is used inside the vehicle, the level of electromagnetic radiation could be higher than when the mobile telephone is connec-ted to an integrated aerial or any other external aerial.
If the vehicle is fitted with a suitable hands-free unit which enables the use of innumerable additional functions of Bluetooth® compatible mobile tele-phones, this will satisfy the legal requirements in many countries which permit the use of a mobile telephone in a vehicle only if a hands-free unit is used.
The factory-fitted hands-free system in your vehicle has been developed for use with mobile tele-phones that are compatible with Bluetooth®_ Mo-bile telephones must be carried in a suitable tele-phone holder or be stored securely in the vehicle. If a telephone holder is used it must be securely at-tached to the base plate. This is the only way to .,.
