O rthopedic Seat Backrest
Some models may be equipped with
orthopedic seats. These seats have
inflatable air cushions built into the
backrest to provide additional lumbar
support. 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 cush­
ion can be 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 be­
tween 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.
