Minimising risk
You can also take your own steps to minimise the risk of unauthorised access to vehicle systems and functions:
—Use only data media, Bluetooth devices and mobile telephones in the vehicle than do not contain manipulated data
or malware.
—Have the vehicle serviced, repaired and maintained only by a correspondingly qualified workshop.
WARNING
Computers, data media and mobile telephones that are connected to the internet or that are used in public and
private networks may be infected by manipulated data or have malware installed on them.
● Protect computers, data media and mobile telephones by means of a suitable anti-virus program and generally
known precautionary measures.
● Regularly update the appropriate anti-virus program with the system updates or upgrades from the provider.
Introduction
The system update is a preventive measure, e.g. to optimise the software and to provide protection against
malware.
A system update allows the software of control units in the vehicle to be updated.
There are two possibilities, depending on vehicle and country:
—System update by a qualified workshop.
—System update by Volkswagen by means of anover-the-air update.
What is a system update?
The “system update” function enables Volkswagen to update the control unit software in the vehicle without you
having to attend a qualified workshop.
Each system update has two phases – download followed by software installation.
The “system update” function is only available in some countries and is not available for all vehicles.
How do I know when a system update is available?
The switched-on Infotainment system indicates that a system update is available.
If several system updates are available for the vehicle at the same time, one system update must first be installed
successfully before the next system update can be executed.
WARNING
It is possible in very rare cases that a control unit will not function properly after a software installation process.
● Do not use the vehicle. Contact Customer Care at Volkswagen Commercial Vehicles.
WARNING
If the digital instrument cluster does not function after software installation, no instruments, warning lamps,
symbols or text messages can be displayed. Driving with a digital instrument cluster that is not working can cause
accidents and fatal injuries.
● Do not use the vehicle. Contact Customer Care at Volkswagen Commercial Vehicles.
A system update may delete any previous action designed to enhance performance or efficiency, such as
engine tuning, that was not performed by Volkswagen AG.
