INTERIOR

The
early
E36

1997
4-door
cars
and
standard

all
1998
models
.
Through
1996,
E36
seatbelts
were
equipped
with
BMW's
original-designspring
tensioners
.
In
1997,
the
seat

de-
sign

modified
to
accommodate
a

tensioners
arede-
signed
to
automatically

.
The
padded
dashboard
houses
the

and
the

.
The
instrument
cluster
uses
large
easy-to-read
analog
instruments
and
is
removable
as
a

dashboard
.
The
Service

of
the
dashboard
comes
in
a
variety
of
four
configurations,
the
most
advanced
being
the
On-Board
Computer
(OBC)
.
See
Fig
.

.
Al¡
versions
of
the
MID
have
a
clock
and
calendar

tion,
different
versions
areequipped
