Service Information
Initialization
Initialization of the panorama glass sunroof involves the following procedures that are
necessary to ensure complete operation of the panorama glass sunroof:
" Normalization
Normalization means locating the mechanical end position at the stop for the tilt
position. This position is stored and is used in calculating the remaining end posi-
tions for the panorama glass sunroof.
" Learning the characteristic curve
The learning procedure registers the closing force necessary for each direction of
the panorama glass sunroof and stores this value.
Complete functionality of the panorama glass sunroof can be guaranteed only by full
initialization.
The initialization procedure can be initiated with the button for the panorama glass
sunroof or via the diagnosis system.
Initialization with the Button
Initialization is performed as follows:
" Press and hold control button in sunroof tilt direction Move both glass roofs into the
tilt position and both blinds into the ventilation position
" After approximately 15 seconds the initialization run starts in the tilt direction and
stores the end position
" The panorama glass sunroof is closed after 5 seconds in the tilt position
" The panorama glass sunroof is then opened and the end position stored.
Note: The control button must remain pressed during the entire initialization
procedure. The initialization procedure must be repeated if the button
is released.
Initialization takes approximately 120 seconds.

Interruption in Power Supply
An interruption in the power supply does not require a new normalization. The initializa-
tion is invalidated if the power supply is interrupted during the initialization or during oper-
ation. A new initialization will then be necessary.
Clearing the Initialization
Initialization is cleared under the following circumstances:
" Failure of the power supply during initialization
" Hall sensor fault detected
" Position implausible
" Certain calls in the diagnostics
" Changed vehicle coding
" Coding data faulty
