MAINTENANCE
Windshield
Wiper
Biade
Maintenance
Common
problems
with
the
windshield
wipers
include
streaking
or
sheeting,
water
drops
after
wiping,
and
blade
chat-
ter
.
Streaking
is
usually
caused
when
wiper
blades
are
coated
with
road
film
or
car
wash
wax
.
Clean
the
blades
using
soapy
water
.
If
cleaning
theblades
does
not
cure
the
problem
then
they
should
be
replaced
.
BMW
recommends
replacing
the
wip-
er
blades
twice
a
year,
before
and
after
the
cold
season
.
Onold-
er
cars,
check
the
tension
spring
that
holds
the
wiper
to
the
glass
.
Replace
the
wiper
arm
if
the
springs
are
weak
.
Drops
that
remainbehind
after
wipingare
caused
by
oil,
road
film,
or
diesel
exhaust
coating
the
windshield
.
Use
an
alcohol
or
ammonia
solution,
or
a
non-abrasive
cleanser
to
clean
the
windshield
.
Wiper
blade
chatter
may
be
caused
by
dirty
or
worn
blades,
bya
dirty
windshield,
or
by
bentor
twisted
wiper
arms
.
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
is
perpendicular
to
the
windshield
atrest
.
Lubricate
the
wiper
linkage
with
a
light
oil
.
The
linkage
is
located
under
the
hood
on
the
drivers
side
.
If
the
problem
persists,
theblades
are
excessively
aged
or
worn
and
should
be
replaced
.
See
611
Wipers
and
Washers
.
Body
and
hinges,
lubricating
The
door
locks
and
lock
cylinders
canbe
lubricated
with
an
oil
that
contains
graphite
.
The
body
and
door
hinges,
the
hood
latch,
and
the
door
check
rods
should
be
lubricated
with
SAE
30
or
SAE
40
engine
oil
.
Lubricate
the
seat
runners
with
multipurpose
grease
.
Do
not
apply
any
oil
to
rubber
parts
.
If
door
weatherstrips
are
sticking,
lubricate
them
with
silicone
spray
or
talcum
powder
.
The
hood
release
cable
should
be
lubricated
as
well
.
The
use
of
winter
lock
de-icer
spraysshould
be
kept
to
an
ab-
solute
minimum,
as
the
alcohol
in
the
de-icer
will
wash
the
grease
out
of
the
lock
assemblies,
and
may
cause
the
locks
to
corrode
internally,
or
become
difficult
to
operate

The
early
E36
cars
areequipped
with
a
single
(driver

airbag
in
the
steering
wheel
.
Startingwith
the
1994
models,
a

Side-impact
airbags
in

front
doors
are
op-

in

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

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
.

The
Multi-Information

unit
in

comes
in
a
variety
of
four
configurations,
the
most
advanced
being
the

Al¡
versions
of

The

On
the

1995),
the

are
disabled
whenever
the

is
locked
in
the
double

.
Beginning
in
January
1995,
the
driveaway
protection
sys-
tem
was
upgraded
to
a
more
sophisticated
system,
called
EWS
