Orthopedic Seat Backrest

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 amount of cushion
height and curvature may be adjusted
after turning the key to steering lock
position 1 or 2.
The inflation pressure of the air cush­
ion can be varied between position
" 0" = without pressure, and position
" 4" = maximum pressure, by chang­
ing the pressure regulator (1) setting.
In addition, the cushion height may be
changed to five different settings
between position " A " = lowest set­
ting, and " E" = highest setting, by
varying the height regulator (2)
adjustment.
If a driving trip is temporarily inter­
rupted, the last cushion setting is
retained in memory, and automatically
adjusts the cushion to this setting
when the trip is continued.
