- with CODE (414) Power glass tilting/sliding roof
- up to Model Year 8

Function requirements:
- No overvoltage or undervoltage
- Terminal 15R ON
- Circuit 15 ON
- Overhead control panel control module (N70) recognizes non-actuated state before actuating switch (roof system switch (N70s1) not actuated for longer than t = 40 ms)

Function
The pop-up roof is opened by pressing the roof system switch (N70s1) upward.

The overhead control panel control module (N70) reads in the status of the roof system switch (N70s1) and actuates the roof system motor (M12m1) as long as the roof system switch (N70s1) is actuated, however, max. only for t = 50 s (maximum activation time). If the maximum activation time is exceeded, further actuation is only possible after the overhead control panel control module (N70) recognizes the non-actuated state of the roof system switch (N70s1). The "Open pop-up roof" function is interrupted when the overhead control panel control module (N70) recognizes a lock-up of the roof system drive unit (M12).

When desynchronized, the "Open pop-up roof" function is restricted.
