Data transmission -> Cyber security for Your Volkswagen Tiguan 4 Door Third Generation (2024-2025)

Data transmission  
Cyber security  
Cyber security describes measures that  
reduce the risk of illegal access to  
vehicle functions, data and control  
modules caused by malware or an  
Internet attack. Of all the components  
in the vehicle, connectivity components  
are most at risk of unauthorized access  
or cyber attacks.  
Connectivity components comprise control modules for data transmission, interfaces, media and diagnostic connections  
through which information and data can be exchanged between the vehicle and mobile devices or the Internet.  
Connectivity components are equipped with security mechanisms to minimize the risk of unauthorized access to vehicle  
systems.  
Connectivity components include in particular:  
Diagnostic connection port  
Control module with installed eSIM card.  
Phone interface  
App-Connect.  
Wi-Fi® hotspot.  
NFC radio technology.  
AUX-IN jack.  
Bluetooth® interface.  
CD/DVD drive.  
USB port.  
SD card slot.  
SIM card slot.  
The type and number of connectivity components present in your vehicle depends on the vehicle equipment and the  
country.  
Software and security mechanisms  
Software and security mechanisms available in the vehicle undergo continuous development. Similar to computers or  
operating systems on cell phones, software and security mechanisms in the vehicle may also be updated at various times.  
System updates improve the security, stability and operating speed of vehicle systems. The system update is a preventative  
measure, for example, to protect from malware and to optimize functionality.  
A system update is used to update the software of control modules in the vehicle.  
Depending on the vehicle and country, there are two ways to update your vehicle:  
System update by a suitably qualified authorized Volkswagen dealer or authorized Volkswagen Service Facility.  
Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.  
System update via an Over-the-Air Update.  
WARNING  
321  
In spite of the integrated security mechanisms and regular system updates or Over-the-Air Updates, malware can cause  
malfunctions in control modules and the vehicle. In the same way, connecting computers, data carriers or cell phones that  
are infected with viruses can result in malfunctions in control modules and the vehicle. Malfunctions may cause serious  
accidents and fatal injuries.  
If the vehicle works or reacts differently to normal, reduce your speed in a controlled manner.  
Contact qualified professionals for assistance. Volkswagen recommends contacting an authorized Volkswagen  
dealer or authorized Volkswagen Service Facility.  
NOTICE  
Malware can access data and information stored in the control modules, in the Infotainment system, on connected data  
carriers and in paired cell phones. This may result in a complete loss of data or damage control modules, the Infotainment  
system, computers, data carriers or cell phones.  
Carry out all pending Over-the-Air Updates as quickly as possible once they are made available, or allow system  
updates to take place. Contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility for  
assistance. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen  
Service Facility.  
Protect computers, data carriers and cell phones with a suitable antivirus program and by taking generally  
recognized precautions. Regularly update the antivirus program using the supplied system updates or upgrades  
provided by the vendor.  
Minimizing risks  
You can actively help to reduce the risk of unauthorized access to vehicle systems and functions by following these  
guidelines:  
Only use data carriers, Bluetooth devices and cell phones in the vehicle that do not contain any manipulated data or  
malware.  
Ensure that system updates provided by Volkswagen are carried out by an authorized Volkswagen dealer or authorized  
Volkswagen Service Facility as soon as possible once they are made available. Volkswagen recommends contacting an  
authorized Volkswagen dealer or authorized Volkswagen Service Facility. If the option to perform an Over-the-Air Update  
is available, depending on the vehicle and country, carry out all Over-the-Air Updates provided by Volkswagen  
immediately. If the Over-the-Air Update is ignored multiple times by the driver, an authorized Volkswagen dealer or  
authorized Volkswagen Service Facility must be contacted for assistance. Volkswagen recommends contacting an  
authorized Volkswagen dealer or authorized Volkswagen Service Facility.  
Only have the vehicle repaired and serviced by suitably qualified professionals. Volkswagen recommends contacting an  
authorized Volkswagen dealer or authorized Volkswagen Service Facility.
