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 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.
