Periodic regeneration
The soot in the particulate filter is burnt off at high temperatures on a periodic basis.
To assist the regeneration of the particulate filter, Volkswagen recommends that you avoid making
only short journeys.
Noises, slight smells and increased engine speeds may occur during regeneration. The radiator fan
may run on while the vehicle is moving or when the engine has been switched off.

During the periodic regeneration process, the yellow indicator lamp does not light up.

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.

Damage to the electrical system can be caused by water entering the system if the rubber cover or

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.

First read and observe the introductoryinformation and safety warnings
These lamps use LED technology. The LEDs cannot be replaced by customers. If some LEDs fail, this
may be an indication that more elements are on the point of failure. In this case, have the lights
checked and renewed if necessary at a qualified workshop.
Changing the front turn signal bulbs

Turn the steering so that the wheel on the affected side of the vehicle is pointing to the
middle of the vehicle. If necessary, start the engine to do this. Then stop the engine again and

Fuses in the engine compartment

Changing a blown fuse
At the time of publication we are unable to provide an complete overview of the locations of the
fuses for the electrical consumers. This is because the vehicle is under constant development,
because fuses are assigned differently according to the vehicle equipment level and because several
electrical consumers may use a single fuse. You can obtain more information about the fuse
assignment from a Volkswagen dealership.
Several electrical consumers can share a single fuse. Conversely, a single consumer could have more
than one fuse.
Therefore fuses should only be replaced when the cause of the fault has been rectified. If a new fuse
blows shortly after fitting, have the electrical system checked by a qualified workshop.

WARNING
High voltages in the electrical system can cause electric shocks, serious burns and death.



WARNING
Using unsuitable or repaired fuses and bridging an electrical circuit without fuses can cause a fire
and serious injuries.

NOTICE
When filling or changing service fluids, please ensure that the correct service fluids are filled through
the correct openings. The use of incorrect service fluids could result in serious malfunctions and
engine damage.

Service fluids that leak from the vehicle are harmful to the environment. For this reason, you should
regularly check the ground underneath your vehicle. If there are spots of oil or other fluids on the
ground, the vehicle should be inspected by a qualified workshop. Any spilt service fluids must be
disposed of properly.

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.

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.
