Hard Top Operation
E93 Complete Vehicle Workbook
53
The RHT consists of three steel panels which fold up into a roof
“package”. This roof package can then be stowed into a space
designated in the trunk.
The steel roof panels continue to use the interior headliner as used
on past convertibles. The liners give the interior a finished appear-
ance and also contribute to noise reduction.
Some of the things to be considered are that the roof panels must
also be secured into the trunk to avoid damage and unwanted
noise. The details of the hydraulics and mechanical operation will
be covered on subsequent pages in this workbook
The mechanical and hydraulic elements in the RHT are designed
to achieve to necessary goals of fast, smooth and quiet operation.
The top can be operated via the switch in the center console, the
mechanical portion of the key and via remote operation. Remote
operation is carried out via the remote control (I.D. transmitter).
This feature is only possible with comfort access.
The convertible top switch is
in the center console.
It is directly connected to the
CTM and provides a ground
input for top operation.
The switch has red and green
LED’s to indicate top status.
The remote control/ID
transmitter is capable of
providing remote operation
only in conjunction with
Comfort Access.
The mechanical key can
operate the top when inserted
into the driver’s door lock.
