by Volkswagen for the respective vehicle type.

Repairs and technical modifications

Volkswagen recommends that you use only ap-

proved Volkswagen accessories and Volkswagen

Genuine Parts^®. These parts and accessories have

been specially tested by Volkswagen for suitability,

reliability, and safety. Volkswagen dealerships are

qualified to install them correctly.

Volkswagen guidelines for repairs and technical

modifications must be followed →

Changes to electronic components and related soft-

ware can cause malfunctions. These malfunctions

can also affect other systems that are related to the

component or software that was modified. The vehi-

cle's operational safety can be seriously jeopardized,

increased vehicle component wear can occur, and

the vehicle may no longer meet applicable emissions

requirements.

Although the market is constantly scrutinized, Volks-

wagen cannot assume responsibility for the reliabili-

ty, safety, and suitability of products Volkswagen

has not approved. Volkswagen can therefore assume

no responsibility for these parts, even if they have

been approved by an official testing agency or are

covered by an official approval certificate.

Volkswagen recommends having all repairs and

technical modifications performed by an authorized

Volkswagen dealer or authorized Volkswagen Serv-

ice Facility using Genuine Volkswagen Parts^®.

WARNING

Improper vehicle modifications and repairs affect

the performance of the airbag system and cause

malfunctions and severe personal injuries.

Damage that is caused by improper repairs or unap-

proved technical modifications will not be covered

by any Volkswagen Limited Warranty.

Never store, mount, or attach objects, such as

cup holders or phone cradles, on or next to the

airbag module covers or within the airbag de-

ployment zones.

WARNING

Improperly performed repairs and modifications

can cause vehicle damage and malfunctions, and

can impair the efficiency of driver assistance sys-

tems. This can lead to accidents and severe per-

sonal injuries.

Objects on or near the surface where airbags

are located can come loose and cause serious

personal injury if the airbag deploys.

WARNING

Have repairs and vehicle modifications done by

an authorized Volkswagen dealer or an author-

ized Volkswagen Service Facility.

Inappropriate spare parts and accessories as well

as improperly performed work, modifications and

repairs can cause vehicle damage, accidents and

serious personal injuries.

Vehicle maintenance

NOTICE

WARNING

Improperly performed repairs and modifications can

cause increased component wear and result in vehi-

cle emissions that no longer meet applicable re-

quirements.

Changing the vehicle's suspension including use of

unapproved tire-rim combinations can change air-

bag performance and increase the risk of serious

personal injury in a crash.

Never install suspension components that do

not have the same performance characteristics

as the components originally installed on your

vehicle.

Repairs and other things that can

affect Advanced Airbag perform-

ance

Never use tire-rim combinations that have not

been approved by Volkswagen.

Repairs and modifications of front bumpers, doors,

front seats, headliners and the chassis can affect

proper airbag performance and should be performed

by an authorized Volkswagen dealer or authorized

Volkswagen Service Facility. These vehicle areas can

contain important parts of the airbag system.

WARNING

Items stored between the safety belt buckle and

the center console can cause safety belt buckle to

send the wrong information to the airbag control

unit and prevent the Advanced Airbag System

from working properly.

Components of the airbag system can be damaged

during removal, assembly and repair activities on the

airbag system itself or related components. Damage

to airbag parts can prevent the system from working

properly in a collision.

Always make sure that nothing can interfere

with the safety belt buckles and that they are

not obstructed.

WARNING

Observe all regulations so that the effectiveness of

the airbag is not affected and to prevent disassem-

bled parts from causing injuries and pollution. Au-

thorized Volkswagen dealers, authorized Volkswa-

gen Service Facilities, and other qualified workshops

are familiar with these regulations.

Improper care and servicing, and improper modifi-

cation and repair work, can increase the risk of

personal injury and death by preventing an airbag

from deploying when needed or deploying an air-

bag unexpectedly:

Never repair, adjust, or change any parts of the

airbag system.

Changing the vehicle's suspension system can

change the way that the airbag system works in

a crash. For example, using tire-rim combinations

not approved by Volkswagen, lowering the vehicle,

changing the stiffness of the suspension, including

the springs, suspension struts, shock absorbers etc.

can change the forces that are measured by the air-

bag sensors and sent to the electronic control unit.

Some suspension changes can, for example, increase

the force levels measured by the airbag sensors and

sent to the electronic control unit and make the air-

bag system deploy in crashes in which it would not

deploy if the changes had not been made. Other

kinds of changes may reduce the force levels meas-

ured by the sensors and prevent the airbag from de-

ploying when it should.

All work on the airbag system, steering wheel,

instrument panel, front seats or electrical sys-

tem (including the installation of audio equip-

ment, mobile telephones and CB radios, etc.)

should be performed by authorized Volkswagen

dealers or authorized Volkswagen Service Facili-

ties. They have the necessary manuals, training,

and special equipment.

The airbag system can be activated only once.

After an airbag has inflated, it must be replaced.

Use only original equipment airbags approved

by Volkswagen. Have them installed by

a trained technician who has the necessary

tools and diagnostic equipment to properly re-

place any airbag in your vehicle and assure sys-

tem effectiveness in a crash.

Never install leather upholstery on a vehicle that

originally had cloth upholstery. Never install cloth

upholstery on a vehicle that originally had leather

upholstery. The capacitive passenger detection sys-

tem for the Advanced Airbag system will not work

properly if different upholstery is installed on the

passenger seat than the upholstery originally instal-

led on the vehicle when it was originally manufac-

tured.

Never permit salvaged or recycled airbags to be

installed in your vehicle.

— upon the order of a court of law or a government

agency; or

— for the defense of a lawsuit through the judicial

discovery process.

Volkswagen may also use the data for research

about vehicle operation and safety performance or

provide the data to a third party for research pur-

poses without identifying the specific vehicle or in-

formation about the identity of its owner or lessee.

Notice about data recorded by the

Event Data Recorder and vehicle

control modules

NOTE: Your vehicle may be equipped with VW Car-

Net. Please see → page 205, Data transfer and the

VW Car-Net Terms of Service and Privacy Policy at

(http:// www.vw.com/carnet) for details regarding

how Volkswagen collects, processes, transmits, uses

and shares information obtained through the VW

Car-Net equipment and service.

This vehicle is equipped with an Event Data Recorder

(EDR). The main purpose of an EDR is to record, in

certain crash or near crash-like situations, such as an

airbag deployment or hitting a road obstacle, data

that will assist in understanding how a vehicle's sys-

tems performed. The EDR is designed to record data

related to vehicle dynamics and safety systems for

a short period of time, typically 30 seconds or less.

The EDR in this vehicle is designed to record such

data as:

Your vehicle is also equipped with a number of elec-

tronic control modules for various vehicle systems,

such as engine management, emission control, air-

bags, and safety belts.

These electronic control modules record data during

normal vehicle operation that may be needed by

trained technicians for diagnostic and repair purpos-

es. The recording capability of these modules is lim-

ited to data (no sound is recorded). Only a small

amount of data is actually recorded over a very lim-

ited period of time, or stored when a system fault is

detected by a control module. Some of the data

stored may relate to vehicle speed, direction, or

braking, as well as restraint system use and per-

formance in the event of a crash. Stored data can al-

so only be read and downloaded with special equip-

ment that is directly connected to the vehicle.

— How various systems in your vehicle were operat-

ing;

— Whether or not the driver and passenger safety

belts were buckled/fastened;

— How far (if at all) the driver was depressing the

accelerator and/or brake pedal; and,

— How fast the vehicle was traveling.

These data can help provide a better understanding

of the circumstances in which crashes and injuries

occur. NOTE: EDR data are recorded by your vehicle

only if a non-trivial crash situation occurs; no data

are recorded by the EDR under normal driving condi-

tions and no personal data (e.g., name, gender, age,

and crash location) are recorded. However, other

parties, such as law enforcement, could combine the

EDR data with the type of personally identifying da-

ta routinely acquired during a crash investigation.

Using a mobile phone in a motor

vehicle when it is not connected to

a vehicle telephone antenna: Some

important things to know

To read data recorded by an EDR, special equipment

is required, and access to the vehicle or the EDR is

needed. In addition to the vehicle manufacturer,

other parties, such as law enforcement, that have

the special equipment, can read the information if

they have access to the vehicle or the EDR.

Mobile or cellular telephones send and receive radio

waves, sometimes called “radiofrequency energy”

(RF energy), both when they are being used and

when they are in standby mode. Current scientific

literature indicates that radio waves that exceed

a certain level can have effects on the human body.

Limits and guidelines have been established by gov-

ernmental authorities and international committees

in an effort to keep the electromagnetic radiation

from mobile phones at levels that will not cause

health problems. However, there is no scientifically

based proof that wireless phones are absolutely

safe.

Some state laws restrict the retrieval or download-

ing of data stored by EDRs installed in a vehicle for

the express purpose of retrieving data after an acci-

dent or crash event without the owner's consent.

Volkswagen will not access the EDR and/or similar

data or give it to others - unless the vehicle owner

(or lessee if the vehicle has been leased) agrees, or;

— upon the official request by the police;

Vehicle maintenance

Therefore, some experts recommend a precaution-

ary approach regarding the use of mobile phones by

taking measures that lower the personal exposure to

electromagnetic fields. When using a mobile tele-

phone inside a motor vehicle without a proper con-

nection to an integrated vehicle telephone antenna,

the personal exposure to electromagnetic fields will

be higher than when using the mobile telephone

while properly connected to an integrated or other

outside vehicle telephone antenna.

WARNING

A mobile phone on the seat, instrument panel or in

other places can be thrown around the inside of

the vehicle during a sudden braking maneuver,

a crash or other accident and injure vehicle occu-

pants.

Never place or attach accessories or other ob-

jects (such as cup holders, telephone brackets,

note pads, navigation systems, large, heavy or

bulky objects) on the doors, on the windshield,

over or near the area marked “AIRBAG” on the

steering wheel, instrument panel, backrests or

between these areas and the occupant. Such

objects could cause serious injury in a collision,

especially if an airbag inflates.

Your vehicle may be equipped with an optional

hands-free system that will permit many of the fea-

tures of compatible Bluetooth^®enabled mobile tele-

phones to be used for greater convenience and is

consistent with the laws of an increasing number of

states and localities that prohibit the use of mobile

telephones without some kind of hands-free device.

WARNING

The hands-free system in your vehicle can be used

with certain mobile phones that are connected by

wire and hardware connector or via compatible

Bluetooth^®enabled phones with a cradle that is de-

signed to fit your mobile telephone. The special cra-

dle offers several advantages: The phone cradle

must be safely secured to the base plate. Your

phone is firmly attached to the instrument panel and

is within reach at all times. Placing the phone in its

cradle permits it to be charged, but more important-

ly connects the mobile phone to the vehicle's out-

side antenna. A mobile telephone that is properly

connected to the integrated or other outside vehicle

telephone antenna will lower the personal exposure

to electromagnetic fields. You should also experi-

ence a better quality of service. Although a mobile

telephone can be used inside your vehicle without

a cradle, the phone will not be securely attached to

the vehicle, will not be charged through the cradle

wiring, and more importantly will not be connected

to the vehicle's integrated telephone antenna. The

mobile phone will also not be recharged. You might

also experience more dropped calls and an overall

impaired quality of the connection.

Using a mobile phone or CB radio inside the vehi-

cle without a properly installed and separate out-

side antenna can be dangerous to your health and

that of your passengers because the electromag-

netic radiation energy that mobile phones and CB

radios emit may be above established limits. This

also applies if the outside antenna is not installed

properly.

Always keep the mobile phone antenna at least

8 in. (20 cm) away from pacemakers. Heart spe-

cialists advise that mobile phones can adversely

affect the way pacemakers work.

Never carry a mobile phone that is switched on

in the breast pocket directly over a pacemaker.

If you suspect there may be interference with

a pacemaker or other medical device, switch the

mobile phone off immediately.

Therefore we strongly recommend that you use your

mobile telephone in your vehicle only when it is

properly attached to an appropriate cradle mounted

on a base plate on the instrument panel.

Because of the large number and variety of mobile

telephones on the market and the frequency with

which new models are introduced, Volkswagen does

not offer cradles for mobile telephones. Please

check with the manufacturer of the mobile tele-

phone that you plan to use.
