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.

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 ⇒:
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 the bulb incorrectly can cause accidents and serious injuries.
•When working in the engine compartment, always read and observe the safety
warnings ⇒ In the engine compartment. The engine compartment of any motor vehicle
is a dangerous area. Serious injuries can be sustained here.
•H7/H15 bulbs are pressurised and could explode when they are being changed.
•Only change the defective bulb once it has had time to cool down completely.
•Never change a bulb unless you are familiar with the procedure. If you are uncertain of
what to do, the work should be carried out by a qualified workshop.
•Do not touch the glass part of the bulb with unprotected fingers. When the light is
switched on, heat will cause fingerprints to evaporate on the bulb, which in turn will
cause the reflector to dim.
•There are sharp-edged parts in the headlight housing in the engine compartment and
on the tail light cluster housing. Protect your hands when changing bulbs.
WARNING
Damage to the electrical system can be caused by water entering the system if the rubber
covers or plastic caps on the headlight housing are not properly mounted after a bulb has
been changed.
NOTICE

Check to see if a fuse has blown Changing fuses.
Follow the instructions to change the affected bulb . Always use identical bulbs with the
same designation. 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. The heat of the bulb would
cause the fingerprint to evaporate and condense on the reflector. This will impair the
brightness of the headlight.
After changing the 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 or may have failed again,
or the connector may have been inserted incorrectly.
Any time you change a bulb in the front of the vehicle, the headlight settings should be
checked by a qualified workshop.

Changing fuses
Introduction
This chapter contains information on the followingsubjects:
⇒ Fuses in the dash panel
⇒ Fuses in the engine compartment
⇒ Fuse table for fuses in the dash panel
⇒ Fuse tables for fuses in the engine compartment
⇒ Changing a blown fuse
At the time of print 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 depending on the vehicle equipment level and because several
consumers may use a single fuse. You can get more information about the fuse layout from a
Volkswagen dealership.
Several electrical consumers could 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 insertion, have the electrical system checked by a qualified workshop as
soon as possible.

Tow-starting or towing
Introduction
This chapter contains information on the followingsubjects:
⇒ Notes on tow-starting and towing
⇒ Fitting the rear towing eye
⇒ Fitting the front towing eye
⇒ Fitting the front towing eye (R-Lineyf
⇒ Driving notes when towing
Tow-starting is where a vehicle is started from it being set in motion by a vehicle that is hitched up
to it.
Towing is where a vehicle that cannot be driven is pulled away with the aid of another vehicle.
Observe any legal requirements when towing or tow-starting.
For technical reasons, vehicles with a discharged 12-volt battery must not be towed.⇒ Jump 
starting
Vehicles with Keyless Access must only be towed with the ignition switched on.
Towing a vehicle when the engine is switched off and the ignition is switched on discharges the 12-
volt vehicle battery. Depending on the charge level of the 12-volt vehicle battery, the drop in voltage
can be large enough after just a few minutes that electrical consumers in the vehicle will no longer
function, e.g. the hazard warning lights.
Jump starting the vehicle incorrectly can cause the 12-volt vehicle battery to explode,
which can lead to serious injuries. Please observe the following in order to reduce the risk
of the 12-volt vehicle battery exploding:
•All work on the 12-volt vehicle battery and the electrical system can cause serious
chemical burns, fire or electric shocks. Always read the warnings and safety
information before carrying out any kind of work on the 12-volt vehicle battery ⇒ 12-
volt vehicle battery.
•Always wear suitable eye protection and gloves and never lean over the 12-volt vehicle
battery.
•Attach the connector cables in the correct order – the positive cable first, followed by
the negative.
•Never connect the negative cable to parts of the fuel system or to the brake lines.
•The non-insulated parts of the battery clamps must not be allowed to touch. The jump
lead attached to the positive terminal on the 12-volt vehicle battery must not touch
electrically conductive parts of the vehicle.
•m/k/a995MK Vehicles with battery in the engine compartment: check the battery
window on the 12-volt vehicle battery. Use a torch for this if necessary. If the display is
light yellow or colourless, do not jump start the vehicle. Seek expert assistance.
•Avoid electrostatic discharge in the vicinity of the 12-volt vehicle battery. The explosive
gas emitted from the 12-volt vehicle battery could be ignited by sparks.
•Do not carry out jump starting if the 12-volt vehicle battery is damaged or if it is or has
ever been frozen.
WARNING
Once the vehicle has been successfully jump-started, go to a qualified workshop and have
the 12-volt vehicle battery checked.
