the chemical components contained in the water. This can also lead to engine failure. If any other
type of water apart from distilled water has been refilled, the fluid in the cooling system should be
completely replaced immediately by a qualified workshop.

Brake fluid

Fig. 190 In the engine compartment: cap on the brake fluid reservoir.
Brake fluid will gradually absorb water from the surrounding air over the course of time. The brake
system will be damaged if there is too much water in the brake fluid. The boiling point of the brake
fluid is also considerably reduced by the water content. Heavy use of the brakes and full braking may
cause a vapour lock in the brake system if the water content is too high. Vapour locks reduce levels
of braking power, considerably increase braking distance and can even cause the brake system to fail
completely. Your own safety and that of other road users depends on having a brake system that
functions properly at all times
Brake fluid specification
Volkswagen has developed a brake fluid that has been optimised for the brake system in the vehicle.
To ensure optimal operation of the brake system, Volkswagen expressly recommends the use of
brake fluid compliant with VW standard 501 14.
Before using a particular brake fluid, check that the brake fluid specifications printed on the
container correspond to the vehicle requirements.

NOTICE
Brake fluid that has leaked or been spilt can damage the vehicle paintwork, plastic parts and tyres.
Immediately wipe off brake fluid that has leaked or been spilt from all parts of the vehicle.

Brake fluid can pollute the environment. Any service fluids that have escaped or been spilt must be

Location of the 12-volt vehicle battery
The 12-volt vehicle battery is located in the engine compartment.
Explanation of the warnings on the 12-volt vehicle battery
Always wear eye protection!Electrolyte is very corrosive and caustic. Always wear
protective gloves and eye protection!Fire, sparks, naked lights and smoking are prohibited!
A highly explosive mixture of gases is given off when the 12-volt vehicle battery is charging!
Always keep children away from electrolyte and the 12-volt vehicle battery!Always
observe the owner's manual!

WARNING
Any work on the 12-volt vehicle battery and the electrical system can cause serious chemical burns,
fire or electric shocks. Always read and observe the following warnings and safety information
before carrying out any kind of work:

Various indicator lamps may light up after the 12-volt vehicle battery has been connected and the
ignition is switched on. They will go out when you drive a short distance at a speed of approximately
15 20 km/h (10 12 mph). If the indicator lamps remain lit up, the vehicle should be checked by a
qualified workshop.

Automatic switch-off for electrical consumers
The intelligent vehicle electrical system management function automatically implements a range of
measures to prevent the 12-volt vehicle battery from discharging under high loads:


power supply to the 12-volt socket and the cigarette lighter may be interrupted temporarily
while the engine is being started.
The vehicle electrics management system cannot always prevent the 12-volt vehicle battery from
being discharged, for example if the ignition is left on over a long period with the engine off or the
side lights or parking lights are left on over a long period of time.

Useful information about wheels and tyres

Handling wheels and tyres
Wheel rims and wheel bolts
Tyre pressure
Tread depth and wear indicators
Tyre damage
Spare wheel or temporary spare wheel
Tyre lettering and tyre type
Maximum load and speed range for tyres
Winter tyres
Snow chains
The tyres are the most heavily loaded and most underestimated parts of a vehicle. Tyres are very
important as the narrow tyre contact surfaces are the only contact between the vehicle and the
road.
The service life of tyres is dependent on tyre pressure, driving style, handling and correct fitting.

WARNING
New tyres or tyres which are old, worn down or damaged cannot provide full vehicle control and

The LongLife mobility guarantee is valid until the next inspection is due. Documentation takes place
at every due inspection.
The type and scope of service work may differ from vehicle to vehicle. Information on specific work
for your vehicle can be requested from a qualified workshop.

WARNING
Inadequate servicing, no servicing at all, or failure to adhere to service intervals can result in
breakdowns, accidents and serious injury.


NOTICE
Volkswagen is not responsible for any vehicle damage caused by inadequate service work or the lack
of part availability.

Regular servicing of your vehicle not only maintains its value, it also ensures that your vehicle
remains roadworthy and in working order. You should therefore have your vehicle serviced
according to the Volkswagen guidelines.

Features of the flexible service
With the flexible service, you only need to have an oil change service carried out if your vehicle
requires one. Individual operating conditions and personal driving style are taken into account in
order to determine this point in time. An important part of the flexible service is the use of LongLife
engine oil instead of conventional oil.

If you do not wish to have the flexible service, you can opt for the fixed service instead. However, a
fixed service can affect your service costs. Your service advisor will be pleased to help.
