Body-General
Seats
4 Anatomically correct seats are constructed from polyure-
10 way seat adjustment thane foam
containing areas or "zones" of different firmness.
They offer good lateral support without constricting the occu-
pant.
The seats have a passive internal ventilation system: Cylin-
drical cavities within the cushions and backrests generate a
pumping effect as the ride motions cause occupant motion.
This
helps remove moisture and feeds fresh air into the seats.
Other features of the seating system:
The seat bases have steel springs for added support and
strength.
The seat control switches are along the outside edge of
the
seat.
Heated seats are an option in all models
In cars equipped with seat position memory, three different
seat confiaurations can be memorized by the seat control
module(s): Seat memory coordinates with outside mirror
memory. These functions are controlled by the seat mem-
ory
module(s).
* For security reasons, the release lever to fold the rear seat
backrest forward is installed in the trunk.
Sport Wagon models: Rear seat
baclts are split 60140, with
the center armrest on the left seat back.
The center armrest incorporates a non adjustable head-
rest. When folded down, the armrest opens out with
cup-
holders and a storage compartment. See 520 Seats for
more details.
instruments and controls
Everything in the interior passengercompartment essential to
the driver is logically grouped and easy to reach. All instru-
ments and controls have been arranged ergonomically and
are fully integrated into the overall design of the vehicle.
Tilt-telescopic steering wheel has
30 mm (1.2 in) of vertical
and longitudinal adjustment.
Multifunction steering wheel contains two
ltey pads con-
taining controls for the sound system, telephone and
cruise control.
Padded dashboard houses the instrument cluster and the
ventilation and heating system.
