Parts, accessories, repairs, and modifications -> Repairs and other things that can affect Advanced Airbag performance for Your Volkswagen Jetta 4 Door Sixth Generation (2011-2018)

Accessories and other things installed in front of the cooling air intakes impair the  
efficiency of the engine coolant. The engine can overheat under high outside temperatures or  
under high engine loads!  
Leaking operating fluids can pollute the environment. Collect leaking operating fluids in suitable  
containers and dispose of them properly in accordance with applicable environmental laws and  
regulations.  
Repairs and technical modifications  
Please first read and note the introductory information and heed the WARNINGS  
Volkswagen guidelines for repairs and technical modifications must be followed ⇒ꢀ  
!
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.  
NOTICE  
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  
Please first read and note the introductory information and heed the WARNINGS  
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.  
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.
