Parts, accessories, repairs, and modifications -> Using a mobile phone without a vehicle-integrated antenna for Your Volkswagen Jetta 4 Door Sixth Generation (2011-2018)

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  
all applicable legal requirements regarding handling and disposal of the vehicle or parts of its 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 vehicle control modules  
Please first read and note the introductory information and heed the WARNINGS  
Your vehicle is not equipped with an Event Data Recorder (EDR).  
EDRs, sometimes called “crash recorders,” are installed by some manufacturers for the express  
purpose of capturing data for retrieval after an accident or crash event.  
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.  
Although your vehicle is not equipped with an EDR, it is 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 also record data during normal vehicle operation for diagnostic and  
repair purposes. Their recording capability is limited to data (no sound is recorded). Only a small  
amount of data is actually recorded over a very limited 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 performance in the event of a crash. Stored data can only  
be read and downloaded with special equipment.  
Using a mobile phone without a vehicle-integrated antenna - some  
important things to know  
Please first read and note the introductory information and heed the WARNINGS  
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 governmental 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.  
Therefore, some experts recommend a precautionary approach regarding the use of mobile phones by  
taking measures that lower the personal exposure to electromagnetic fields. When using a mobile  
telephone inside a motor vehicle without a proper connection 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.  
Your vehicle may be equipped with an optional hands-free system that will permit many of the features  
of compatible Bluetooth® enabled mobile telephones 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.  
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  
designed to fit your mobile telephone. The special cradle 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 importantly  
connects the mobile phone to the vehicle's outside 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 experience 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.  
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 telephone that you plan to use.

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 occupants.  
Never place or attach accessories or other objects (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.

WARNING  
Using a mobile phone or CB radio inside the vehicle without a properly installed and separate  
outside antenna can be dangerous to your health and that of your passengers because the  
electromagnetic 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  
specialists 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.
