standard 501 14 is available from Volkswagen dealerships.
If this brake fluid is not available and it is necessary to use another high-quality brake fluid instead,
brake fluid that is compliant with DIN ISO 4925 CLASS 4 or US standard FMVSS 116 DOT 4 can be
used.
Not all brake fluids that are compliant with DIN ISO 4925 CLASS 4 or US standard FMVSS 116 DOT 4
have the same chemical composition. Some of these brake fluids may contain chemicals that can
damage or destroy brake system components over time.
Volkswagen therefore recommends the use of brake fluid that is compliant with VW standard 501 14
to ensure sustained proper operation of the brake system.
Brake fluid that is compliant with VW standard 501 14 fulfils the requirements of DIN ISO 4925
CLASS 4 or US standard FMVSS 116 DOT 4.
Brake fluid level
The brake fluid level must always be between the MIN and MAX marking on the brake fluid reservoir
or above the MIN marking
The brake fluid level cannot be checked accurately in all models as engine components may partially
conceal the fluid level in the brake fluid reservoir. If the brake fluid level cannot be read exactly,
please go to a qualified workshop.
The brake fluid level drops slightly during vehicle operation as the brake pads wear and the brakes
are automatically adjusted.

The indicator lamp lights up red.
Brake fluid level is too low.
Do not drive on! Check the brake fluid level.
If the brake fluid level is too low, inform a qualified workshop. Have the brake system checked.
Changing the brake fluid
The brake fluid should be changed by a qualified workshop. Volkswagen recommends using a
Volkswagen dealership for this purpose. Only brake fluid that conforms with the required
specification should be used.

WARNING
Brake failure or reduced braking efficiency can be caused by the brake fluid level being too low or by
brake fluid that is too old or unsuitable.

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:

First read and observe the introductoryinformation and safety warnings
The electrolyte level of the 12-volt vehicle battery should be checked regularly in high-mileage
vehicles, in hot countries and in older 12-volt vehicle batteries. The 12-volt vehicle battery is
otherwise maintenance-free.
Vehicles with an auxiliary heater Auxiliary heater and ventilationare fitted with special vehicle
batteries. The electrolyte level of these 12-volt vehicle batteries cannot be checked for technical
reasons. Go to a qualified workshop to have the 12-volt vehicle battery checked.

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:

while the engine is being started.
The vehicle electrics management system cannot always prevent the 12-volt vehicle battery from

Tyre monitoring system
Introduction
This chapter contains information on the followingsubjects:
Tyre Pressure Loss Indicator
Troub
The tyre monitoring system warns the driver when the tyre pressures are too low.
The tyre monitoring system monitors various parameters (for example, rolling circumference) of all
wheels using ABS sensors (indirect measurement).

WARNING
The intelligent tyre monitoring system technology cannot overcome the laws of physics, and
functions only within the limits of the system. Incorrect handling of the wheels and tyres can lead to
a sudden loss of pressure in the tyres, tread separation and even tyre blow-out.

Tyre

Tyre pressure

the cold tyre to the recommended tyre pressure for the tyres installed on your vehicle Tyre
pressure
amage.


If the tyre pressure is too low, this will increase fuel consumption and tyre wear.

When new tyres are driven at high speeds for the first time, they can expand slightly and trigger a
one-off pressure warning.

Old tyres should be replaced only by tyres that have been approved by Volkswagen for the vehicle
type.

Do not rely solely on the tyre monitoring system. Check your tyres regularly to ensure that they are
properly inflated and have no signs of damage, such as punctures, cuts, cracks, and blisters. Remove
any objects that become embedded in the tyre tread but have not penetrated into the body of the
tyre itself.
Tyre Pressure Loss Indicator
First read and observe the introductoryinformation and safety warnings
Functional description
The Tyre Pressure Loss Indicator uses data from the ABS sensors and other functions to compare the
speed of rotation and the rolling circumference of the individual wheels.
The rolling circumference can change:

The Tyre Pressure Loss Indicator may react with a delay or not display anything at all in the event
of a sporty driving style, when driving on snow-covered or icy roads or unpaved roads or when
driving with snow chains.

Troubleshooting

After a warning about the tyre pressure being too low, switch the ignition off and then back on
again. The Tyre Pressure Loss Indicator can be re-synchronised only after this has been done.
