authorized Volkswagen dealer or authorized Volkswagen Service Facility. Volkswagen recommends contacting an authorized

Volkswagen dealer or authorized Volkswagen Service Facility.

If the windshield is damaged within the sensors' and camera's range, for example by a stone chip, then the windshield must b

replaced. Stone chip repairs can cause malfunctions in the driver assistance system. After the windshield has been replaced,

the cameras and sensors must be set and calibrated by suitably qualiﬁed professionals. Volkswagen recommends contacting

an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

Repairs and technical modiﬁcations

Volkswagen guidelines must be followed when performing repairs and technical modiﬁcations ⇒

Interference with electronic components and their software can cause malfunctions. Because of the way electronic

components are interconnected, such malfunctions can also impair systems that are not directly involved. This means that yo

risk both a substantial reduction in the operational safety of your vehicle and increased wear of vehicle components.

An authorized Volkswagen dealer or authorized Volkswagen Service Facility cannot assume any liability for damage resulting

from repairs and technical modiﬁcations that were performed incorrectly.

An authorized Volkswagen dealer or authorized Volkswagen Service Facility is not responsible for damage resulting from

repairs and technical modiﬁcations that were performed incorrectly. Such damages are also not covered by the Volkswagen

warranty.

Diagnostic connection (on-board diagnosis)

In the vehicle interior, there is a diagnostic connection (OBD ) to read event memories. Event memories document faults that

have occurred and deviations from speciﬁed values from the control module ⇒

The diagnostic connection (OBD) is located in the footwell on the driver's side on the underside of the instrument panel or nex

to the hood release lever behind a cover.

Only have the event memory read out and reset by suitably qualiﬁed professionals. Additional information about the saved

data can be obtained from suitably qualiﬁed professionals. Volkswagen recommends contacting an authorized Volkswagen

dealer or authorized Volkswagen Service Facility.

After a malfunction is ﬁxed, the information about it will be deleted from the event memory. Other memory content is

overwritten continuously.

Vehicles with special modiﬁcations and mountings

The attachment and mounting manufacturer should make sure that the applicable environmental laws and regulations are me

for the attachments and mountings, especially the EU directive 2000/53/EG about old vehicle and EU directive 2003/11/EG

about market introduction restrictions and the use of certain hazardous materials and compounds.

The installation instructions for any retroﬁtted equipment should be saved by the vehicle owner and provided to the removal

facility if the vehicle is scrapped. This ensures that even vehicles with retroﬁtted equipment will be disposed of in a way that

will not harm the environment.

Engine/motor protection

Engine/motor protection can reduce the risk of damage to the vehicle underbody and the oil pan, for example if driving over

curbs, entering driveways, or on unpaved roads.

Have the retroﬁtting work performed by suitable qualiﬁed professionals. Volkswagen recommends contacting an authorized

Volkswagen dealer or authorized Volkswagen Service Facility.

Engine/motor protection may not be available in all countries.

WARNING

Repairs and modiﬁcations to the vehicle that are performed incorrectly can impair the effectiveness of the driver

assistance systems and deploying airbags. This can cause malfunctions and accidents and serious injuries or death.

Only have suitably qualiﬁed professionals make repairs or modiﬁcations to a vehicle. Volkswagen recommends

contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

WARNING

452

Repairs and modiﬁcations to the vehicle that are performed incorrectly, for example due to the use of unsuitable parts,

may cause vehicle damage, accidents, and serious or fatal injuries.

Only install parts on the vehicle whose design and function are identical to the parts installed at the factory.

Only use rim/tire combinations that are approved by Volkswagen for your vehicle model. More information can be

obtained from suitably qualiﬁed professionals. Volkswagen recommends contacting an authorized Volkswagen

dealer or authorized Volkswagen Service Facility.

Only have suitably qualiﬁed professionals make repairs or modiﬁcations to a vehicle. Volkswagen recommends

contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

Volkswagen recommends the use of Volkswagen original parts or Volkswagen original accessories. Volkswagen

has veriﬁed their reliability, safety, and suitability.

WARNING

Incorrect use of the diagnostic connection may cause malfunctions, resulting in accidents and serious or fatal injuries.

Never read out the event memory yourself using the diagnostic connection.

Never load data yourself using the diagnostic connection in the vehicle.

Only have the event memory read out with the diagnostic connection by suitably qualiﬁed professionals.

Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

Airbag system repairs and situations that can affect the system function

Volkswagen guidelines must be followed when performing repairs and technical modiﬁcations ⇒

Only have modiﬁcations and repairs on the front bumper, doors, front seats, headliner, or vehicle body performed by an

authorized Volkswagen dealer or authorized Volkswagen Service Facility. Volkswagen recommends contacting an authorized

Volkswagen dealer or authorized Volkswagen Service Facility. Airbag system components and sensors may be located on

these vehicle components.

Airbag system components can be damaged during all procedures on the airbag system and when removing and installing

system components while performing other repair procedures. This may prevent the airbags from deploying or cause them to

deploy incorrectly in the event of an accident.

The instructions must be followed so that the effectiveness of the airbags is not impaired and removed components do not

cause injuries and environmental pollution. An authorized Volkswagen dealer or authorized Volkswagen Service Facility will

be familiar with these provisions. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized

Volkswagen Service Facility.

A modiﬁcation to the vehicle suspension can impair the functionality of the airbag system during a collision. For example,

using a rim/tire combination that is not approved by Volkswagen, lowering the vehicle, or changing the suspension stiffness

including the springs, suspensions struts, shock absorbers, etc., can change the force that is measured by the airbag sensors

and transmitted to the electronic control module. For example, some changes to the suspension can increase the force

measured by the systems and trigger the airbag system in accidents where the airbags would normally not be deployed if the

modiﬁcations had not been made. Other modiﬁcations can reduce the force measured by the sensors and prevent the airbag

from deploying when it should have deployed.

WARNING

Using unsuitable replacement parts and accessories may cause damage and malfunctions in the vehicle and impair the

effectiveness of the airbag system. These problems may also occur if work, modiﬁcations and repairs are done incorrectly.

This could lead to damage to the vehicle and accidents resulting in serious or fatal injuries.

453

Only have suitably qualiﬁed professionals make repairs or modiﬁcations to a vehicle. Authorized Volkswagen

dealers and authorized Volkswagen Service Facilities have the required tools, diagnostic devices, repair

information, and qualiﬁed personnel. Volkswagen recommends contacting an authorized Volkswagen dealer or

authorized Volkswagen Service Facility.

Note that the airbag module cannot be repaired but must instead be replaced.

Never install airbag components removed from old vehicles or from recycling.

Only install parts on the vehicle whose design and function are identical to the parts installed at the factory.

WARNING

Modiﬁcations to the vehicle suspension including using a rim/tire combination that is not permitted may change the

functionality of the airbag. This can cause serious or fatal injuries in the event of an accident.

Never install suspension components that do not have the same properties as the original parts installed in the

vehicle.

Only use rim/tire combinations that are approved by Volkswagen for your vehicle model. More information can be

obtained from suitably qualiﬁed professionals. Volkswagen recommends contacting an authorized Volkswagen

dealer or authorized Volkswagen Service Facility.

Mobile phone usage in the vehicle

Electromagnetic waves

When using a mobile phone or radio equipment without connecting to the exterior antenna, the electromagnetic waves will no

be deﬂected outward in an optimum way. Increased waves in the vehicle interior can occur, especially when reception is poor,

for example in rural areas. This could be a potential health risk ⇒

Depending on the equipment, it may be possible to use a suitable telephone interface to connect the mobile phone to the

exterior antenna. This will improve the connection quality and increase the range.

Using a phone

In many countries, using a phone in the vehicle is only permitted if there is a hands-free connection, for example using a

Bluetooth^®connection. Before using the phone, secure it in a suitable holder ⇒

or store it in a storage compartment, suc

as in the center console, to prevent it from sliding around.

Radio

If operating radio devices, follow the legal regulations and the user guide from the manufacturer. The aftermarket installation o

radio devices is subject to approval.

Contact qualiﬁed professionals for more information about installing radio equipment. Volkswagen recommends contacting an

authorized Volkswagen dealer or authorized Volkswagen Service Facility.

WARNING

Mobile devices that are loose or not secured correctly can be thrown through the vehicle interior during sudden driving or

braking maneuvers or in the event of a collision and cause severe injuries.

Secure or store the mobile phone and accessories safely and outside of the deployment range of the airbags.
