Parts, accessories, repairs, and modifications  
Parts and accessories  
Volkswagen recommends that you consult an authorized Volkswagen dealer or authorized Volkswagen Service Facility before purchasing accessories, spare parts  
or other equipment. Always do so if you want to install additional accessories or replace parts. Your authorized Volkswagen dealer or authorized Volkswagen  
Service Facility can provide information about legal requirements and factory-recommended accessories, spare parts, and other equipment.  
WARNING  
Improper vehicle modifications and repairs affect the performance of the airbag system and cause malfunctions and severe personal injuries.  
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 deployment  
zones.  
Objects on or near the surface where airbags are located can come loose and cause serious personal injury if the airbag deploys.  
WARNING  
Inappropriate spare parts and accessories as well as improperly performed work, modifications and repairs can cause vehicle damage, accidents and serious  
personal injuries.  
Volkswagen strongly recommends to only use accessories approved by Volkswagen and Genuine Volkswagen Parts ®. These parts and accessories have  
been evaluated by Volkswagen for their suitability, reliability and safety.  
Have repairs and vehicle modifications performed by an authorized Volkswagen dealer or authorized Volkswagen Service Facility. Authorized Volkswagen  
dealers and authorized Volkswagen Service Facilities have the required tools, diagnostic equipment, repair information, and trained personnel to properly  
replace any airbag in your vehicle and assure system effectiveness in a crash.  
Only install parts on the vehicle that are consistent with factory-installed parts with respect to design and characteristics.  
333  
Only use wheel rim/tire combinations approved by Volkswagen for the respective vehicle type.  
Repairs and technical modifications  
Volkswagen guidelines for repairs and technical modifications must be followedꢀ!  
Changes to electronic components and related software can cause malfunctions. These malfunctions can also affect other systems that are related to the  
component or software that was modified. The vehicle's operational safety can be seriously jeopardized, increased vehicle component wear can occur, and the  
vehicle may no longer meet applicable emissions requirements.  
Volkswagen recommends having all repairs and technical modifications performed by an authorized Volkswagen dealer or authorized Volkswagen Service Facility  
using Genuine Volkswagen Parts®.  
Damage that is caused by improper repairs or unapproved technical modifications will not be covered by any Volkswagen Limited Warranty.  
WARNING  
Improperly performed repairs and modifications can cause vehicle damage and malfunctions, and can impair the efficiency of driver assistance systems. This  
can lead to accidents and severe personal injuries.  
Have repairs and vehicle modifications done by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.  
NOTE  
Improperly performed repairs and modifications can cause increased component wear and result in vehicle emissions that no longer meet applicable  
requirements.  
Repairs and other things that can affect Advanced Airbag performance  
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.  
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.  
Observe all regulations so that the effectiveness of the airbag is not affected and to prevent disassembled parts from causing injuries and pollution. Authorized  
Volkswagen dealers, authorized Volkswagen Service Facilities, and other qualified workshops are familiar with these regulations.  
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 airbag 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 airbag 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 measured by the sensors and prevent the airbag from deploying when it should.  
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 system for the Advanced Airbag system will not work properly if different upholstery is installed on the passenger seat than the  
upholstery originally installed on the vehicle when it was originally manufactured.  
WARNING  
Changing the vehicle's suspension including use of unapproved tire-rim combinations can change airbag 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.  
Never use tire-rim combinations that have not been approved by Volkswagen.  
WARNING  
Leaving the optional safety belt extender attached to the safety belt buckle on the front passenger seat when the safety belt is not being used will prevent the  
Advanced Airbag System from working properly and can increase the risk of serious personal injury in a collision.  
Leaving the extender attached to the safety belt buckle when the front seat is occupied and the safety belt is not being used will signal to the airbag control  
unit that the front passenger seat is occupied and that the safety belt is being used. The electronic control unit for the airbag system will then receive  
incorrect information that will  
cause the safety belt pretensioner to deploy unnecessarily in collisions and  
cause the front passenger airbag to deploy later in collisions in which the front airbag would otherwise be triggered earlier to help protect an  
unrestrained front seat passenger.  
Always remove the safety belt extender when it is not needed and stow it safely.  
334  
Never use the safety belt extender to secure a child restraint.  
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.  
Always make sure that nothing can interfere with the safety belt buckles and that they are not obstructed.  
WARNING  
Improper care and servicing, and improper modification and repair work, can increase the risk of personal injury and death by preventing an airbag from  
deploying when needed or deploying an airbag unexpectedly:  
Never repair, adjust, or change any parts of the airbag system.  
All work on the airbag system, steering wheel, instrument panel, front seats or electrical system (including the installation of audio equipment, mobile  
telephones and CB radios, etc.) should be performed by authorized Volkswagen dealers or authorized Volkswagen Service Facilities. 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 replace any airbag in your vehicle and assure system effectiveness in a crash.  
Never permit salvaged or recycled airbags to be installed in your vehicle.  
Undeployed airbag modules and safety belt pretensioners are classified as Perchlorate Material. Special handling may apply – see  
restraint system, including airbag modules and safety belts with pretensioners. Authorized Volkswagen dealers and authorized Volkswagen Service Facilities  
are familiar with the requirements, and we recommend that you have them perform this service for you.  
Notice about data recorded by the Event Data Recorder and vehicle control modules  
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 systems 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:  
How various systems in your vehicle were operating;  
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  
a non-trivial crash situation occurs; no data are recorded by the EDR under normal driving conditions 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 data routinely acquired  
during a crash investigation.  
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.  
Some state laws restrict the retrieval or downloading of data stored by EDRs installed in a vehicle for the express purpose of retrieving data after an accident 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;  
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 purposes without  
identifying the specific vehicle or information about the identity of its owner or lessee.  
NOTE: Your vehicle may be equipped with VW Car-Net. Please see VW Car-Net®ꢀ and the VW Car-Net Terms of Service and Privacy Policy at (  
equipment and service.  
Your vehicle is also equipped with a number of electronic control modules for various vehicle systems, such as engine management, emission control, airbags, and  
safety belts.  
These electronic control modules record data during normal vehicle operation that may be needed by trained technicians for diagnostic and repair purposes. The
