Orthopedic Seat Backrest - Mercedes-Benz 300 SL Operator's Manual

Orthopedic Seat Backrest

1. Pressure regulator
2. Height regulator
Some models may be equipped with
orthopedic seats. These seats have an
inflatable air cushion built into the
backrest to provide additional lumbar
support.
The pressure and height regulators are
located on the driver's seat on the left,
on the passenger's seat on the right.
The amount of cushion height and
curvature may be adjusted after turning
the key to steering lock position 2.
The inflation pressure of the air
cushion can be continuously varied
between position "0" = without
pressure, and position "4" = maximum
pressure, by changing the pressure
regulator (1) setting.
In addition, the cushion height may be
changed to five different settings
between position "a" = lowest setting,
and "e" = highest setting, by varying
the height regulator (2) adjustment.
If the engine is turned off, the last
cushion setting is retained in memory,
and automatically adjusts the cushion
to this setting when the engine is
restarted.
