'necking fluid level
Pe :orrect fluid level is essential to the sat-
:~=
:tory operation of the brake system. The
fc. Z level must always be between the
AX"
and "MIN" marks.
~- a "evel of fluid tends to sink slightly when
"a vehicle is used due to the automatic ad- ::ment of brake linings. This is quite nor-
-rwever, if the level sinks noticeably in a
srorttime or drops below the "MIN" mark
re system may be leaking. A low fluid level " the reservoir is indicated by the brake
w.arning lamp lighting up (see page 48 also), .nen this happens take car to a Volks­
wagen dealer immediately and have the
cake system checked. Renewing brake fluid
Brake fluid absorbs moisture. In the course
of time it takes in water from the ambient
air. Too high a content of water in the brake
fluid can in time cause corrosion damage in
the system. Furthermore the boiling point of
the brake fluid is reduced considerably. For
this reason the brake fluid must be renewed every two years.
Attention
When the brake fluid becomes
too old vapour bubbles can form in the brake system when the
brakes are used hard. The
effi­

ciency of the brakes and thus the
vehicle safety is then seriously

affected.
Only use our genuine brake fluio (see: - ra­
tion to US standard FMVSS 116 DO~-
.
~-e
fluid must be new.
Attention Brake fluid is poisonous!
It must therefore only be stored in the closed original container
out of reach of children.
Remember also that brake fluid will
attack the paintwork. Because of the disposal
prob­

lems,
the special tools necessary
and the specialist knowledge re­
quired,
the brake fluid changing
should preferably be done by a
Volk­
swagen
dealer.

It is advisable to have the fluid change car­
ried out during an Inspection Service.

Changing
the wheels round If
the
front
tyres are worn more than the rear
it
is
advisable
to
change
the
wheels round

as
shown.
All
tyres will then have approxi­ mately
the
same length
of
service life.
With certain types
of
tread wear
it
can be an advantage
to
change the wheels diagonally.

Volkswagen
dealers have
the
necessary
in­

formation.
Renewing wheels/tyres

Wheels
and tyres are important design
fea­
tures. The wheels and tyres approved by us should be
used.
They are specially matched
to
the
model concerned
and
contribute largely
to the
excellent road holding
and

safe
driving characteristics.

Volkswagen
dealers have the up-to-date in­
formation
on
which brands
of
tyres are ap­ proved
by us.

• Fitting
and
repairing tyres requires
ex­
pert knowledge and special tools. This work
may only be carried out by specialist person­

nel.

djn
Because
of the
problem
of dis-
<^>
posing
of the old
tyres,
the

special
tools
necessary
and the
specialist
knowledge
required,
tyre
changing
should
preferably
be
done

by
a
Volkswagen
dealer.

Furthermore, many Volkswagen dealers
stock
an
attractive range
of
wheels
and

tyres.
•
For
safety reasons
the
tyres should
be
renewed
in
pairs and
not
singly. The tyres

with
the deepest tread should always be on
the
front
wheels. • Only combine radial
ply
tyres
of the

same
type,
size
(rolling circumference) anc if possible
the
same tread pattern
on all 4

wheels.

•
If the
spare wheel differs from
the
ver­
sion
fitted
on the
vehicle (e.g. winter tyres
or wide tyres)
the
spare may only
be
usee briefly
to
replace
a
flat
tyre
and
with
an
ap­propriately careful style
of
driving.
It
mus:
be replaced
with
the
normal wheel as soor

as
possible.
• Never
fit
used tyres where their previous history
is not
known.

GENERAL
MAINTENANCE
Arduous
operating
conditions
ne vehicle construction and equipment is
resigned for normal operating conditions.
his also applies to the frequency and the
extent of the maintenance laid down in the
service
Schedule.
f the vehicle is used in arduous operating
conditions (e.g. continuous trailer towing,
exceptionally high or low ambient tempera-

:ures,
very dusty conditions, poor quality

ruel,
etc.) it may be necessary to carry out
special
technical preparations, such as ;hanging the oil to the appropriate viscosity, ^stalling special air cleaners, modifying the
ignition timing etc. Furthermore, the main­
tenance must also be matched to the oper­
ating conditions - see also page 93.
Driving
abroad

If the vehicle is to be taken abroad, the fol­
lowing must also be borne in mind:
• If the vehicle has a catalytic converter, one must ensure
that
unleaded petrol will be available during the journey - see
page 86.The automobile clubs offer infor­ mation about the unleaded filling station
network.
• Although there are more than 10 000
Volkswagen
dealers all over the world to
service
Volkswagen vehicles there are
countries in which only a limited amount of

service
is available or none at all.
• In certain countries it is also possible
that
your vehicle model is not soid so
that
certain
spare
parts will not be available or
that
the

Volkswagen
personnel are not familiar
with
the repair procedure should anything go
wrong.
The Volkswagen
Sales
Centres in Germany or the
Importer
concerned will be only too
pleased
to give advice on the necessary
technical preparation of the vehicle, on the maintenance required and on the repair

possibilities.

The addresses are given in the vehicle wallet. • When the vehicle is used in a country
which drives on the opposite side of the road to the home country the wedge

shaped
areas on the headlight lenses must be masked - see page 129.

Driving
on
holiday

Before starting off note the following
points:
• The roadworthiness and driving safety are particularly important when on holiday-

see
page 78.
• With a fully laden vehicle and/or roof rack, the handling changes. The driving
style must be adapted to the different condi­
tions - more information on loading is given
on page 28.
The
tyre
pressures must be checked - see
page147.

• When a trailer is to be towed, there are many special points to note - see page 81.
• If an oil change or an Inspection Service
is
probably going to become necessary dur­
ing the
trip,
it is advisable to have this work
done before going on holiday if possible.

In winter the following points should be
noted:
• Winter weather is particularly hard on the
battery
and it should therefore be
checked,
preferably by a Volkswagen
dealer, before the onset of cold weather. If the vehicle is not driven for several weeks
when the temperatures are very low, the
battery
should be taken out - for
further
in­
formation see page 107.
• On a vehicle
with
a Diesel engine, winter
Diesel
must be used at temperatures below
0 degrees C - see page 87.
• The water should be drained out of the
Diesel
fuel
filter
before the onset of
winter.

This
operation is also included in the Lubri­ cation
Service.

• The anti-freeze in the cooling system should be checked before the cold
season
starts - see page 101.
• The engine oil viscosity must be correct for the ambient temperature - see page 99.
• Particularly in
winter,
frequent washing and waxing of the vehicle is the best way to protect it against harmful environmental in­

fluences.
• In winter the windscreen washer
sys­

tem should always be filled
with
a window
cleaning solution containing an anti-freeze
additive.
• To remove snow and ice
from
the win­ dows and mirrors, a plastic scraper should be used - see page 90.
• The road holding and handling can be im­ proved in winter road conditions by the use
of winter or All-weather tyres - see pages 114and146.
• When driving in mountainous districts in winter it is advisable to take snow chains

with
you. On some such roads, snow chains
are obligatory - see also page 114.

Masking
headlights

When the vehicle is used in a country which drives on the opposite side
of
the road to the
home country,
the
asymmetric dipped neadlights
will
dazzle oncoming
traffic.

To prevent this,
the
wedge-shaped sector on the headlight lenses must be covered
up

with
an
opaque adhesive strip.
The illustration shows
the
strip installed
for

the change
from
right
hand
to
left
hand
traffic.
Installing
radio

When service installing
a
radio
or
replacing
a
set
installed
by the
factory
the
following points should
be
noted:
•
The
connection*
in the
vehicle
is for
Genuine
Volkswagen radios11
from
Model

Year
1988. The supply plug has the following
wire colours and connections:
Red/white Permanent positive

Brown Negative
(-)
vehicle earth
Grey/blue
Instrument

on/

off. On no account use this
connection
for
operating
voltage supply.
Blue/white*
Speed
signal
for
automatic volume control
•
Radios
with
other connections must
be
connected
with
an adapter cable which can

also
be obtained
from
a Volkswagen dealer.
11 Not available
in all
export markets
Attention

On
no account cut wires off and
leave
them
without
insulation. If

necessary
use a proper adapter.
Otherwise the wiring can be
overloaded or short circuits can
occur
- Fire danger!
Apart from this important elec­
tronic components can be damaged or the functioning impaired. If for
example the speed signal is
dis­

turbed this can lead to
faulty
man­ agement of engine, automatic gear­box, ABS etc.

Even
connecting the speed signal to
radio sets
with
speed dependent
vol­
ume control from other manufac­
turers can cause
such
faults.

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.
