INTERIOR
EQUIPMENT

0013195

The
early
E36
cars
areequipped
with
a
single
(driver
side)
airbag
in
the
steering
wheel
.
Startingwith
the
1994
models,
a
dual
airbag
Supplemental
Restraint
System
has
been
stan-
dard
equipment
.
Side-impact
airbags
in
the
front
doors
are
op-
tional
in
1997
4-door
cars
and
standard
equipment
in
all
1998
models
.

Through
1996,
E36
seatbelts
were
equipped
with
BMW's
original-designspring
tensioners
.
In
1997,
the
seat
base
de-
sign
was
modified
to
accommodate
a
pyrotechnic
(explosive
charge)
seatbelt
tensioner
.
Both
types
of
tensioners
arede-
signed
to
automatically
tension
the
belts
by
about2
inches(55
mm)
in
the
event
of
a
collision
.

The
padded
dashboard
houses
the
instrument
cluster
and
the
ventilation
and
heating
system
.
The
instrument
cluster
uses
large
easy-to-read
analog
instruments
and
is
removable
as
a
unit
without
removing
the
dashboard
.
The
Service
Inter-
val
Indicator
(SII)
will
remind
the
driver
when
thecar
requires
service
.
See
620
Instruments
.

The
Multi-Information
Display
(MID)
unit
in
thecenter
of
the
dashboard
comes
in
a
variety
of
four
configurations,
the
most
advanced
being
the
On-Board
Computer
(OBC)
.
See
Fig
.
4
.

Al¡
versions
of
the
MID
have
a
clock
and
calendar
.
In
addi-
tion,
different
versions
areequipped
with
a
"check

display
for
fuel-economy
information
