Additional bulb specifications
Some bulbs in headlights or in tail light clusters might have factory specifications that are different to
standard bulbs. The designation is inscribed on the bulb, either on the glass part or on the base.

WARNING
Accidents can occur if roads are not sufficiently illuminated and other road users have difficulty
seeing the vehicle, or cannot see it at all.

WARNING
Changing bulbs incorrectly can cause accidents and serious injuries.

NOTICE
Damage to the electrical system can be caused by water entering the system if the rubber cover or
plastic covers on the headlight housing are not properly mounted after a bulb has been changed.
Checklist Information on changing bulbs

First read and observe the introductoryinformation and safety warnings⇒Introduction 
Checklist
Always carry out the following actions for changing a bulb in the given order ⇒ :

Park the vehicle on a firm and level surface at a safe distance from the flow of traffic.

Switch on the electronic parking brake Electronic parking brake.

Turn the light switch to position 0 Switching lights on and off.

Move the turn signal and main beam lever to neutral position Switching turn signals on and off.

Automatic gearbox: move the selector lever to position P DSG® dual clutch gearbox.

Stop the engine and remove the vehicle key from the ignition Starting the engine.

Manual gearbox: select a gear Manual gearbox: selecting a gear.

Allow the orientation lighting to go out Coming Home and Leaving Home function (orientation
lighting).

Leave the defective bulbs to cool down.

Check to see if a fuse has visibly blown Changing fuses.

Follow the instructions to change the affected bulb . Always replace bulbs with identical bulbs of the
same type. The designation is inscribed on the bulb, either on the glass part or on the base.

Do not touch the glass part of the bulb with unprotected fingers. When switched on, the heat of the
bulb would cause the remaining fingerprint to evaporate and be deposited on the reflector. This will
impair the light output of the headlight.

After changing a bulb, check to ensure that the bulb is working properly. If the bulb is not working
properly, the bulb may not have been inserted properly, may have failed again, or the connector
may have been fitted incorrectly.

Any time you change a bulb at the front of the vehicle, the headlight settings should be checked by a
qualified workshop.

WARNING
Ignoring any of the items on this important safety checklist can lead to accidents and severe injuries.


NOTICE
Always take care when removing or fitting lights to prevent damage to the paintwork or to other
vehicle parts.

Brake fluid that is compliant with VW 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.
Brake fluid level
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.

Do not work on the electrical system unless you are familiar with the task, aware of the general
safety procedures and have the correct equipment, service fluids and suitable tools. Serious injuries
can be caused by carrying out work incorrectly ⇒ . All work should be carried out by a qualified
workshop. Volkswagen recommends using a Volkswagen dealership for this purpose.
