Phase 2

The sunroof switch must be released ("Position zero") and immediately pressed again within 1.5 seconds. The sunroof is now closed at maximum power without anti-trapping protection. The actuation time of the SHD motor is a maximum of 15 s. In the event of blocking, the SHD motor still receives current until the higher-level motor protection of 15s kicks in or the sunroof lid is moved into the end position.

For safety reasons, it must always be possible to open the sunroof. Releasing the button discontinues the panic close immediately.

If the sunroof is in the lift position, the panic close function cannot be triggered.

As of a vehicle speed of >16 km/h (10 mph), panic close does not function.
