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
"check

LOCKING
SYSTEM
AND
ELECTRONIC
IMMOBILIZATION
The
central
locking
system
uses
electrical
lock
actuators
at
each
door
and
at
the
trunk
lid
.
The
locking
system
can
be
ac-
tuated
by
either
front
door
lock
or
by
the
luggage
compartment
lock
.
Onsome
1994
and
later
cars,
an
additional
remote
con-
trol
keypadcan
also
be
used
to
activate
the
lock
and
anti-theft
systems
.
When
the
key
is
tuned
to
the
lock
position,
a
micro-switch
signals
a
central
control
module
to
lock
all
doors,
luggage

gas
tank
flap
and,
in
later
convertibles,
the
glove

.
Where
applicable,

ELECTRICAL
SYSTEM-GENERAL
Voltage
and
Voltage
Drops
The
wires,
connectors,
and
switches
that
carry
current
are
designed
with
very
low
resistance
so
that
current
flows
with
a
minimum
loss
of
voltage
.
A
voltage
drop
is
caused
by
higher
than
normal
resistance
in
a
circuit
.
This
additional
resistance
actually
decreases
or
stops
the
flow
of
current
.
A
voltage
drop
can
be
noticed
byproblems
ranging
fromdim
headlights
to
sluggish
wipers
.
Some
common
sources
of
voltage
drops
are
corroded
or
dirty
switches,
dirty
or
corroded
connections
or
contacts,
and
loose
or
corroded
ground
wires
and
ground
con-
nections
.
A
voltage
drop
test
is
a
good
test
to
make
if
current
is
flowing
through
the
circuit,
butthe
circuit
is
not
operating
correctly
.
A
voltage
drop
test
will
help
to
pinpoint
a
corroded
ground
strap
or
a
faulty
switch
.
Normally,
there
should
be
less
than
1
volt
drop
across
most
wires
or
closed
switches
.
A
voltage
drop
across
a
connector
or
short
cable
shouldnot
exceed
0

NOTE-
The
maximum
voltage
drop
in
an
automotive
circuit,
as
recommended
by
the
Society
of
AutomotiveEngineers
(SAE),
is
as
follows
:
0

;
0

Volts
for

;
0

for

;
and
0
.3volts
for
switch
or
solenoidcon-
tacts
.
On
longer
wires
or
cables,
the
drop
may
be
slight-ly
higher
.
In
any
case,
a
voltage
drop
of
more
than
1.0volt
usually
indicates
a
problem

The
continuity
test
can
beused
to
check
a
circuit
or
switch
.
Because
most
automotive
circuits
are
designed
to
have
little
or
no
resistance,
a
circuit
or
part
of
a
circuit
canbe
easily
checked
for
faults
using
an
ohmmeter
.
An
open
circuit
or
a
cir-
cuit
withhigh
resistance
will
not
allow
current
to
flow
.
A
círcuit
with
little
or
no
resistanceallows
current
to
flow
easily
.
When
checking
continuity,
the
ignition
should
be
off
.
On
cir-
cuits
that
are
powered
at
all
times,
the
battery
should
be
dis-
connected
.
Using
the
appropriate
wiring
diagram,
a
circuit
can
be
easily
tested
for
faulty
connections,
wires,
switches,
relays,
and
engine
sensorsby
checking
forcontinuity
.

A
short
circuit
is
exactly
what
the
narre
implies
.
The
circuit
takes
a
shorter
paththan
it
was
designed
to
take
.
The
most
common
short
that
causes
problems
is
a
short
to
ground
where
the
insulation
on
a
positive
(+)
wire
wears
away
and
the
metal
wire
is
exposed
.
When
the
wire
rubs
against
a
metal
partof
thecar
or
other
ground
source,
the
circuit
is
shorted
to
ground
.
If
the
exposed
wire
is
live
(positive
battery
voltage),
a
Puse
will
blow
and
the
circuit
may
possibly
be
damaged

Cleaning
Problems
Common
cleaning
problems
with
thewipers
includestreak-
ing
or
sheeting,
waterdrops
after
wiping,
and
blade
chatter
.
Streaking
is
usually
caused
when
wiper
blades
are
coated
with
road
film
or
car
wash
wax
.
Clean
the
blades
using
soapy
water
.
If
cleaning
does
not
cure
the
problem,
the
blades
should
be
replaced
.
BMW
recommends
replacing
the
wiper
blades
twice
a
year,
before
and
after
the
cold
season

Wiper
blade
chatter
may
be
caused
by
dirty
or
worn
blades,
or
by
wiper
arms
that
areout
of
alignment
.
Clean
the
blades
and
windshield
as
described
above
.
Adjust
the
wiper
arm
so
that
there
is
even
pressure
along
the
blade,
and
so
that
the
blade
at
rest
is
perpendicular
to
the
windshield
.
If
problems
persist,
theblades
and
wiper
arms
should
be
replaced
.
The
wiper
blades
can
be
renewed
in
one
of
two
ways
:
either
by
replacing
the
complete
blade
or
by
replacing
just
therubber
insert
.
Insert
replacement
is
the
mosteconomicalmethod,
al-
though
overtime

itselfwill
become
