How do I recognize an upcoming system update?

When the Volkswagen ID.4 is switched on, the Infotainment system will notify you if a system update is available.

If multiple updates are pending, each update must be completed successfully before the next can begin.

WARNING

In rare cases, a system update may cause temporary malfunctions in control modules of the Volkswagen ID.4.

This could lead to unexpected vehicle behavior and potentially dangerous situations.

• If abnormalities occur, reduce speed safely and seek professional assistance immediately.

WARNING
