Fig. 184 On the instrument cluster display: the bonnet is open or has not been closed properly.
A symbol in the instrument cluster display Fig. 184indicates if the bonnet is open or is not closed
properly.
Do not drive on! If necessary, lift the bonnet and then close it again.
This symbol is also visible when the ignition is switched off and will go out a few seconds after the
vehicle has been locked when all doors are closed.

WARNING
Failure to observe warnings can cause your vehicle to break down in traffic, which can lead to
accidents and serious injuries.

The symbol can differ depending on the version of the instrument cluster.
Service fluids and consumables
All service fluids and consumables, e.g. tyres, coolant and vehicle batteries, are being constantly
developed. The same applies to toothed belts, engine oils and spark plugs for combustion engines,
for example. For this reason, service fluids and consumables should be replaced at a qualified
workshop. Volkswagen dealerships always have the latest information about any changes.

WARNING
Unsuitable service fluids and consumables, and the incorrect use of these fluids and consumables,
can cause accidents, serious injuries, burns or poisoning.

Leaking service fluids can pollute the environment. Spilt service fluids must be collected in suitable
containers and disposed of properly and with respect for the environment.
Washer fluid

The washer fluid level should be checked regularly and topped up as necessary.
A strainer is located in the neck of the washer fluid reservoir. The strainer keeps large dirt particles
away from the windscreen washer jets when refilling. The strainer should be removed for only
cleaning. If the strainer is damaged or is not present when refilling, dirt particles can enter the
system and block the washer jets.

Never mix coolant additive or other unsuitable additives into the washer fluid. These may leave an

Engine oil
Introduction
This chapter contains information on the followingsubjects:
Engine oil standards
Changing engine oil
Engine oil consumption
Checking the engine oil level and refilling the engine oil
Troubleshooting
The engine oils are not only tailored to the requirements of engines and exhaust gas treatment
systems, but also to fuel quality. Due to the way in which a combustion engine works, engine oil
always comes into contact with combustion residues and fuel, which has corresponding effects on
the ageing process of the oil. The correct engine oil is important for the function and service life of
the engine. A special multigrade high-lubricity oil has been filled at the factory and this can normally
be used as an all-season oil.

This chapter contains information on the followingsubjects:

procedures and have the correct equipment, service fluids and suitable tools. Serious injuries can be

Coolant and coolant additives can pollute the environment. Spilt service fluids must be collected
then disposed of properly and in an environmentally responsible way.
Coolant specification
First read and observe the introductoryinformation and safety warnings
The cooling system is filled at the factory with a mixture of specially prepared water and at least 40%
coolant additive G 13 (TL-VW 774 J).
The proportion of engine coolant additive must always be at least 40% to protect the cooling system.
If greater frost protection is required in very cold climates, the proportion of anti-freeze additive can
be increased. However, the percentage of coolant additive should not exceed 60%, as this would
reduce the frost protection again and the cooling effect.

NOTICE

Refill only with distilled water. All other types of water can cause corrosion in the engine due to
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.
