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
.

.

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

installed

.

The
E36
cars
are
equipped
with
a
sophisticated
centralized

body
electric/electronics
plan
.
The
system
is
self-diagnostic

and
incorporates
many
functions
into
a
single
control
module
.

The
consolidation
of
several
systems
into
a
single

module
minimizes
power
requirements
and
the
incorporation

of
the
diagnostic
link
results
in
more
efficient
and
accurate

troubleshooting
.

Self-diagnostic
codes
are
accessible
electronically
through

the

Two
versions

.

1992
and
1993
models
are
equipped
with
a
central

(ZVM)
which
incorporates

the

E36

are
equipped

.
This
is
an
electronic

that

includes

:

Electronic
Immobilization
System

Beginning
in
model
year
1994,
all
E36
vehicles
incorporate

adriveaway
protection
system
regardless
of
whether
the
vehi-

cle
is
equipped
with
a
BMW
Alarm
System
or
an
On-Board

computer
.
Two
types
of
factory
systems
were
installed,
de-
pending
on
vehicle
production
date
.

On
the
early
system
(model
year
1994
up
to
January
1995),

the
ignition
and
fuel
injection
functions
are
disabled
whenever

the
vehicle
is
locked
in
the
double
lock
mode
.
This
is
referred

lo
as
EWS
or
EWS
I
.

Beginning
in
January
1995,
the
driveaway
protection
sys-

tem
was
upgraded
to
a
more
sophisticated
system,
called

EWS
II
.
This
system
uses
a
wireless
communication
link
be-

tween
a
transponder
chip
in
the
ignition
keyand
the
ring
an-

tenna
