Arm Rest (Front Seats); Orthopedic Seat Backrest - Mercedes-Benz 420 SEL 1989 Owner's Manual

Arm Rest (Front Seats)

Position 1 = arm rest folded up.
Position 2 = for normally inclined seat
back.
Position 3 = for extremely inclined
seat back.
To adjust arm rest downwards, press
release button (4).
Note:
To move the arm rest between posi­
tions 1 and 2 it may be necessary to
overcome a slight resistance.
Warning!
The arm rest does not suffice as
a child restraint system. In case
of a frontal collision a child can
be catapulted forward over the
locked arm rest. Infants and
small children should be seated
in a properly secured restraint
system that complies with US
Federal Motor Vehicle Safety
Standard 213 and Canadian
Motor Vehicle Safety Standard
213.1.

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 bet­
ween 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 re­
started.
