GENERAL MAINTENANCE
Paint damage

Small marks in the paint such as scratches
or stone damage should be touched up im­ mediately with paint (Volkswagen touch-up
stick or spray can) before the metal starts to rust.
However, should rust be found at any time
it must be removed thoroughly and then the
area treated first with an anti-corrosion primer and then the correct paint applied.
You can of course have this work done by a
Volkswagen dealer.
The number of the original vehicle paint is given on the data sticker (see page 154 ).

Windows
Remove snow and ice from windows and
mirrors with a plastic scraper only. To avoid
scratches due to dirt on the glass, the
scraper should only be pushed in one direc­
tion and not moved to and fro.
Traces of rubber, oil, wax, grease or silicone
can be removed with a window cleaning
sol­
ution or a silicone remover.
The windows should also be cleaned on the inside at regular intervals. Do not dry the windows with the leather
used for the paintwork because traces of
paint cleaner will cause streaks to appear on
the glass.
To avoid damaging the
heating element
wires
in the rear window do not put
stickers over the wires on the inside.

Door, boot
and
window
weatherstrips

The weatherstrips will remain flexible and last longer if they are rubbed lightly with a
rubber protective compound from time to

time.
This will also stop the weatherstrips
from freezing on in the winter.

Plastic parts
and
leatherette

Exterior plastic parts are cleaned with nor­
mal washing and interior parts with a damp

cloth.
If this is not sufficient, these parts and leatherette may only be cleaned with

special solvent-free
plastic cleaners.
Curtains

The curtains may only be cleaned chemi­ cally. They should not be washed as the.
could shrink, and/or the fire-resistant prop­erties could be washed out.

Upholstery cloth
and
textile
trim

Upholstery cloth and textile trim on doc-
panels, parcel shelves, luggage compart­ ment covers, headlining etc. must be
cleaned with special cleaners or dry foarr
and a soft brush.

Cleaning seat belts Keep belts clean
because they may nc:
retract properly if very dirty.
Dirty belts can be cleaned by washing with
a mild soap solution without taking the belt; out of the vehicle.

Note
Inertia reel belts should be completely dr.
before they are allowed to roll up.

GENERAL
MAINTENANCE

Attention
Do
not have the belts cleaned

chemically
because the cleaning

compounds
damage the webbing
material. Ensure
that
the belts do not come into contact
with
cor­

rosive
fluids.

Steel wheels
~ne wheels and
the
wheel trims should
be
:!eaned
thoroughly
at
regular intervals .'.hen the vehicle
is
being washed. This
will

"event brake dust,
dirt
and road salt
from
•cumulating
on the
wheel. Persistent "grained brake dust can
be
removed
with

="
industrial grime remover. Paint damage ;~ould
be
repaired before rust can form.
Alloy wheels - order
to
maintain
the
smart appearance
• alloy wheels
for a
long period, regular pre
is
necessary.
In
particular, salt
and

•Bke
pad dust must
be
washed
off
thor-

cghly
at
least every two weeks otherwise re surface
of the
alloy
will
be
damaged.
-~er
being washed,
the
wheels should
be

~f3ted
with
an
acid-free cleaner
for
alloy
"eels.
About every three months
it is

"f:essary
to
give wheels
a
good rubbing
». :n hard wax. Paint polish or other abrasive
•c
„tions must not be
used.
If
the protective

BE
-.t
coat has been damaged, e.g. by stone react,
the
damaged spots should be dealt
with
as soon
as
possible.
Cleaning and anti-corrosion
treatment
of
engine compart­ ment

Attention Before doing any
work
in the en­
gine compartment it is essential
to read the notes on page 95!

The
engine compartment and
the
outside
surface
of
the power
unit
are given anti-cor­
rosion treatment
at the
factory.
In
the
winter when
the
vehicle
is
being
driven frequently
on
salted roads, good
anti-corrosion treatment
is
very important.
For
this reason
the
entire engine compart­
ment should
be
thoroughly cleaned before
and after
the
salting period
and
then pre­

served
so
that
the
salt cannot have
a
dam­
aging effect. The
ignition must be switched off
before washing the engine.

To
prevent damage to the system
the jet from the cleaning appliance must not be directed into the
intake

openings
for the heating and venti­lation. The openings are located
above the air cleaner.
If
the engine compartment is cleaned
at
any
time
with
grease removing solutions1'
or if

one has the engine washed, the anti-corro­
sion
compound is nearly always removed as

well.
It is
therefore essential
to
ask
for
dur­

able
preservation
of all
surfaces,
seams,

joints
and components
in the
engine com­ partment
to
be carried out. This applies also
when corrosion protected parts
are re­
newed.

Volkswagen
dealers have stocks
of the
high-quality cleaning and preservation ma­
terials recommended
by the
factory
and
have
the
equipment necessary
to
apply
them.
Because
when
washing
the en­

gine
petrol,
grease
and oil de­

posits
are
washed
off, the
dirty
water
must
be
cleaned
by an oil
sep­

arator.
For
this
reason
engine
wash-
11
Only
the
correct
cleaning
solutions may
be
used
-
on no account petrol
or
Diesel.

GENERAL
MAINTENANCE

Checking
coolant
level

The
expansion tank
is in the
engine
com­
partment on the bulkhead
-
see Fig.

The
correct coolant level
is
essential
to
the satisfactory operation
of
cooling system.
For
this reason, the coolant level should
be

checked
regularly,
and
this
is
best done
when refueling.

The
level
can
only
be
checked properly
when engine
is
not running.

The
coolant level must be between the MIN
and
MAX marks
on the
expansion tank
when engine
is
cold
and can be
slightly
above
the MAX mark when
it
is warm.
When
the
coolant level
is too low on ve­

hicles
with
an automatic coolant level moni­
toring device,
it is
indicated by the coolant
temperature/coolant level warning lamp
flashing continuously (see page 47).

Coolant
losses

Coolant
loss normally indicates leaks in the

system.
In
this
case
the
cooling system
should
be checked by a Volkswagen dealer

without
delay.
It is
not sufficient merely
to

add
coolant.
In
a
sealed system
losses
can only occur
if

the boiling point
of
the coolant is exceeded
as
a
result
of
overheating, and coolant
is

forced out
of
the system.
Overheating can occur
if:

• the flow
of
cooling air is reduced, e.g.
by
a
radiator
muff,
very
dirty
radiator fins
(leaves,
dust, insects)
or
additional driving
lights
in
front
of
the cooling air intake.
• the boiling point
of
the coolant has been lowered by an incorrect mixture
-
see previ­

ous
page.
•
the
radiator
fan is not
working
- see
"Fan"
on next page
-
or, • the vehicle
is
driven up
a
long hill
in too

low a gear
with
engine speed very high and
at very high ambient temperatures
-
see
"Fan"
on
next page.
If
the
cause
of the
overheating cannot
be

found
and
eliminated, contact
a
Volks­
wagen dealer
as
soon
as
possible other­

wise
serious damage may
be
done
to the
engine.

Topping
up
coolant
Switch
engine
off
and let
it
cool down. Then

cover
expansion tank cap
with
a
cloth and

turn
cap carefully
to
the
left
and remove.

Attention
Do
not
remove
expansion
tank

cap
when
engine
is
hot
-
Danger
of scalding.

System
is
under
pressure.

If, in an
emergency only water
can be

added,
the
correct mixture concentration must be restored
with
the specified coolant
additive (see previous page)
as
soon
as
possible.

DO-IT-YOURSELF
• The radios from the Genuine Volks­ wagen Accessory Programme11 are similar
to those used in the factory and ensure
trouble-free installation. These sets are in keeping
with
the advanced technology and
well-planned easy-to-operate design. In
Germany
there is also an Exchange Service
for these radios so
that
even after years of
use
a set requiring repair can be exchanged

cheaply
for a completely reconditioned,

good-as-new
set by a Volkswagen dealer.
• Loudspeakers,
fitting
parts, aerials and
suppression
kits should also be taken from
the Genuine Volkswagen Accessory
Pro­

gramme11. These parts have all been

specially
developed for each vehicle model. • When installing the aerial it is essential to
ensure
that
the hole provided by the factory
where the aerial enters the body is sealed
very carefully. In addition the aerial cable,
the connecting wires and the loudspeaker
wires must be routed so
that
they cannot
chafe,
rattle
or get tangled up
with
moving parts (e.g. pedals, steering, heating controls
etc.). Otherwise the operation of the
con­

trols may be affected or vehicle safety im­
paired.

In
cases
of doubt, exact information can be
obtained from Volkswagen dealers.

TECHNICAL
DESCRIPTION

Attention
Due to high temperatures which
can occur in the catalytic
con­

verter in very unfavourable conditions, the vehicle should not be parked so that the catalyt­
ic converter can come into
con­

tact with inflammable materials.
If whilst driving, the engine mis­
fires, loses power and runs uneven­ ly,
this
could be due to a fault in the ignition system. In a
case
like this,
unburnt fuel can enter the exhaust
system and then escape to atmos­
phere.
Furthermore, the catalytic
converter could become damaged
due to overheating. The vehicle
speed must be reduced immediately
and the defect should be eliminated
at the nearest Volkswagen dealer.
Note
Even
in the
case
of a
perfectly working
ex­

haust emission control system there can, under certain engine operating conditions,
be
a
sulphur-type exhaust
smell.

This
depends upon
the
sulphur content
in
the fuel being
used.
Quite often this can
be
remedied
by
select­
ing another brand
of
fuel
or,
filling
up
with

unleaded premium petrol.
50
kW
Diesel
engine

An
oxidation catalytic converter
is
fitted
in

the exhaust system
of
this Diesel engine.
It
consists
of
a steel-cased ceramic body
con­

taining
a
multitude
of
longitudinal
passages

which are vapour coated
with
platinum. The catalytic converter largely eliminates
the
unpleasant smelling hydrocarbons
and

turns carbon monoxide
into
carbon dioxide.
In addition
an
exhaust
gas
turbocharger
forces
air
into
the
cylinder, causing
the
en­
gine
to
operate
with
a high
excess
of
air. The
fuel which is then injected in is so complete­ ly
burnt,
that
under
full
load soot is no longer
visible
in the
exhaust.

As
the
diesel engine catalytic converter
does
not get
hotter than
a
conventional
ex­
haust system, under normal conditions
there
is
nothing special
to be
noted, this

applies
also
to
parking.
The system does
not
require any additional

care
or
maintenance.
Activated
charcoal
filter*

Vehicles
with
a
regulated catalytic
con­

verter,
in
Germany
and
other export countries, have
a
fuel system which
in­

cludes
an activated charcoal
filter
(petrol va­pour accumulator).
The activated charcoal
filter
prevents
the

fuel vapour escaping
into
the
atmosphere.

These
vapours
pass
into
a
container filled

with
activated charcoal and, when
the en­
gine
is
stationary they
are
accumulated
in

the activated charcoal. When
the
engine
is
running,
the
container
is
automatically
ventilated
by
opening
a
valve
and the
fuel
vapour
is fed
into
the
engine
for
combus­
tion.
The system works completely automati­

cally
and
is
maintenance-free.
