Event data recorder
The vehicle is not fitted with an event data recorder.
Event data recorders temporarily store vehicle information. This provides precise information in the
event of an accident. In vehicles with an airbag system, data that might be relevant in the event of
an accident can be stored, e.g. impact speed, belt buckle status, seat positions and trigger speed.
The scope of the data is manufacturer-specific.
An event data recorder may only be fitted if the owner has approved the procedure. This is covered
by legislation in some countries.
Reprogramming control units
All data for the control of components are stored in the control units. Some convenience functions,
such as lane change flash, single door unlocking and displays, can be reprogrammed using special
workshop equipment. If this is the case, the descriptions in your vehicle wallet will no longer
correspond with the original functions. Volkswagen recommends that you have any reprogramming
confirmed in the service schedule under Workshop comments.
Information about possible reprogramming can be obtained from the Volkswagen dealership.
Reading the vehicle's event memory
A diagnostic interface for reading the event memories is located in the vehicle interior ⇒. Data
relating to the function and status of the electronic control units are stored in the event memory.
Additional information on the stored data is available from qualified workshops.
The diagnosis interface is located behind near the fuse box in the footwell on the driver side.
The event memory should only be read and reset by a qualified workshop.
After a fault has been rectified, the information in the memory pertaining to the fault is deleted.
Other memory content is overwritten on an on-going basis.
Using a mobile telephone in the vehicle without a connection to the
external aerial
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Both during telephone calls and in standby mode, mobile telephones transmit and receive radio
waves, which may also be termed "high-frequency energy". Current scientific literature warns us
that radio waves can be harmful to human beings if they exceed certain limits. Government bodies
and international committees have introduced threshold values and guidelines to ensure that
electromagnetic radiation produced by mobile telephones does not pose a hazard to health.
However, there is no proven scientific evidence that demonstrates that cordless telephones are
absolutely safe.
For this reason, some experts are calling for more precautions to be taken in the use of mobile
telephones, by taking steps to reduce the level of personal exposure to electromagnetic radiation.
If a mobile telephone that is not connected to the vehicle's external aerial is used inside the vehicle,
the level of electromagnetic radiation could be higher than when the mobile telephone is connected
to an integrated aerial or any other external aerial.
If the vehicle is fitted with a suitable hands-free unit which enables the use of innumerable
additional functions of Bluetooth compatible mobile telephones, this will satisfy the legal
requirements in many countries which permit the use of a mobile telephone in a vehicle only if a
hands-free unit is used.
The hands-free system of the portable navigation device (delivered by Volkswagen) in your vehicle
has been developed for mobile telephones that are compatible with Bluetooth⇒ Portable
navigation device. Mobile telephones must be located in a suitable telephone holder or be stored
securely in the vehicle. If a telephone holder is used it must be securely attached to the base plate.
This is the only way to ensure that the mobile telephone is securely attached to the dash panel and
always within reach of the driver. Depending on the hands-free system, the connection between the
mobile telephone and the external aerial is established either via the telephone holder or via an
existing Bluetooth connection between the mobile telephone and the vehicle.
Connecting the mobile telephone is to a telephone aerial integrated in the vehicle or to an external
telephone aerial reduces the electromagnetic radiation generated by the telephone which could
affect the human body. Using an aerial also improves the quality of the signal.
Incorrect use of the diagnostic interface can cause faults, which can result in accidents and
serious injuries.
•Never read the event memory using the diagnostic interface yourself.
•The diagnostic interface should only be read by a qualified workshop.

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.

Changing bulbs
 Introduction
This chapter contains information on the followingsubjects:
⇒ Information on changing bulbs
⇒ Changing bulbs in the front headlights
⇒ Changing bulbs in the front bumper
⇒ Changing bulbs in the tail light cluster
⇒ Changing the bulb in the number plate light
⇒ Changing bulbs in the side turn signals
Changing the vehicle bulbs requires considerable technical skill. If you do not feel confident with the
procedure, Volkswagen recommends that you have the bulbs changed by a Volkswagen
dealership, or that you seek other expert assistance. Contact a qualified workshop if other vehicle
parts around the lights need to be removed.
You should keep a box with spare light bulbs for the lights that ensure the vehicle is roadworthy in
the vehicle at all times. Spare bulbs are available from Volkswagen dealerships. In some countries
it is a legal requirement to have these spare bulbs in the vehicle.
It may be illegal to drive with a defective bulb in the exterior lighting.
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.

NOTICE

Park the vehicle on a firm and level surface at a safe distance from the flow of traffic.
Apply the handbrake firmly Braking, stopping and parking.
Turn the light switch to position 0 Lights.
Shift the turn signal lever to neutral Lights.
Automated manual gearbox: move the selector lever to D or R Changing gear.
Stop the engine and remove the vehicle key from the ignition Starting and stopping the
engine.
Manual gearbox: select a gear Changing gear.
Leave the defective bulbs to cool down.
Check to see if a fuse has blown 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.
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
⇒ Preparation for working in the engine compartment. The engine compartment of any
motor vehicle is a dangerous area. Serious injuries can be sustained here.
•H4, HB4 and H7 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 could be caused by water entering the system if the rubber
cover on the headlight housing is not properly mounted.
