DRIVING
TIPS

• Where possible make
full
use of the maximum permissible drawbar weight on

call
of the towing bracket - see page 151 -
cut do not exceed it.
• While observing the permissible trailer
and
drawbar weight, distribute the load in
the trailer so
that
heavy objects are as near
as
possible to the axle. The objects must
a
so be secured so
that
they cannot slip
aoout.
• Check the
tyre
pressures on the towing
/ehicle
and the trailer.
• The headlight settings, should be
:hecked
with
trailer attached before mov- ng off and adjusted as necessary.

On
vehicles
with
headlight beam control it

is
only necessary to
turn
the knurled disc in
:ash
in the appropriate direction.
Driving
instructions

To
obtain the best possible handling of ve­
hicle
and trailer, the following should be

noted:

• Try to avoid driving
with
an unladen ve­
hicle
and a loaded trailer. If this cannot be

avoided,
only drive slowly to allow for the unfavourable weight distribution.
• As driving stability of vehicle and trailer
decreases
when the speed increases do not
drive at the maximum permissible top
speed
in unfavourable road, weather or
wind conditions - particularly when going downhill. In any
case
the speed must be reduced im­
mediately the trailer shows the slightest

sign
of snaking. On no account try to stop
the snaking by accelerating.
• For safety reasons one should not drive faster than 80 km/h (50 mph). This also
applies
in countries where higher speeds
are permitted. • Always brake in good time. If the trailer

has
an overrun brake, apply the brakes gen­
tly at
first
then firmly. This will avoid the
jerk­
ing caused by the trailer wheels locking.

Change
down before going down a steep hill so
that
the engine can act as a brake.
• When a long climb in a low gear
with
ex­ tremely high engine revs must be nego­
tiated at exceptionally high ambient tem­peratures the coolant temperature gauge must be observed. When the gauge needle

moves
to the
>~zza'
e~z of :ne
scale,
the road speed must be reduced immediately. If nevertheless ~g amp flashes,
stop immediately and si ow the engine to

cool
off at idling speed for several minutes.
• The cooling effect of the radiator fan
can­
not be increased by changing down, be­

cause
the speec of t~e
~a~
s ~o! dependent
on the engine
speed.
One should therefore not change down even when towing a
trailer as long as :-e e-g -e zar cope with­ out the vehicle speed dropping too much.

Petrol
additives

The
quality of the fuel has a decisive influ­
ence
upon the running behaviour, perform­

ance
and service life of the engine. The addi­
tives which are mixed into the petrol are of particular significance. One is advised
therefore only to use good
quality
pet­
rol
containing
additives.

If such fuel is not available, or if engine
troubles such as starting difficulties, stalling during idling, vibration and loss of power
occur,
the appropriate additives should be
mixed
with
the petrol when filling the tank.
At temperatures between about 0 and 15
degrees
C, these additives prevent possible icing up of the carburettor, have an anti-cor­
rosion effect, clean the fuel system and pre­
vent deposits building up in the engine.

Petrol
additives available in accessory
outlets have not all shown themselves to be
effective. Therefore additives which have

been
tested for
Volkswagen
engines are av­

ailable
from Volkswagen dealers in
Ger­
many and in many export countries. The

Volkswagen
dealers are also informed
with
regard to the use of additives, and they know what to do in
cases
where deposits

have
already built up.

GENERAL
MAINTENANCE
Care
of car

Regular
and
careful
care
helps
to

maintain
the
value
of the
vehicle.

Furthermore
it can be one of the

stipulations
for the
upholding
of

warranty
claims should corrosion

damage
and
paint
defects
occur.

Every
Volkswagen dealer carries stocks
of

suitable car care materials. The instructions
for use on the container should be followed.

Attention

•
If
misused,
car
care
materials
can
be
injurious
to
health.

•
Car
care
materials
must
al­

ways
be
stored
in a
safe
place

where
they
are out of the
reach
of
children.

When
buying
car
care
materials

one
should
select
products

which
do not
damage
the
environ­

ment.
Empty
containers
which
these
materials
were in do not be­

long
with
household
waste.
Washing

The
best protection against environmental

influences
is frequent washing and waxing.

How
often this treatment
is
required
de­

pends,
amongst other things on
how
much
the vehicle is
used,
how
it
is parked (garage, in open under trees etc.),
the
seasons,

weather conditions
and
environmental
in­
fluences.

The
longer bird droppings, insects, tree
resin,
road
and
industrial grime,
tar
spots,
soot, road salt
and
other aggressive
ma­

terials remain on
the
vehicle paint the more lasting their destructive effect will be. High
temperatures e.g. from strong sunlight
in­

tensifies
the
corrosive effect.
In certain circumstances weekly washing

can
be
necessary,
in
other conditions monthly washing
with
appropriate waxing
may
be
fully adequate.
After
the
period when salt
is put on the

roads
the underside
of
the vehicle should al­

ways
be
washed thoroughly.
Automatic
wash
plants

The
vehicle paint
is so
durable
that
the ve­

hicle
can normally be washed without prob­

lems
in an
automatic wash plant. Howeve'
the influence on the paint depends
to
a large extent
on the
design
of the
plant,
the
filter­
ing
of
the wash water, the type
of
wash anc

care
material, etc.
If
the paint has a
matt
ap­
pearance
after going through
the
wash
plant
or is
even scratched this should
be

brought
to the
notice
of the
plant operate
immediately.
If
necessary
a
different wash
plant should
be
used.

Notes

• Before going through
the
wash plant, apart from
the
usual precautions (closing
windows and sliding roof, retracting the aer­ial) there
is
nothing further
to
note. How­

ever,
to
prevent damage
the
door mirrors

should
be
folded
in.

•
If
there are special
fittings
on the vehicle - such as spoilers, roof rack, two-way radio
aerial
etc.
it is
best
to
speak
to the
plant op­erator.

should

only
be
washed

bays.
In
some
districts,
washing

elsewhere
may
even

be
forbidden.

Irst
soften the
dirt
with
plenty of water and
-ise
off as well as possible.
~nen clean the car
with

cersistent
dirt.

=
:nse
the sponge or glove out thoroughly at
snort intervals.

.'.'heels
and sill panels should be cleaned
last, using a different sponge if possible.
After cleaning the vehicle, rinse thoroughly
vith
water and leather it off.
Notes

• The vehicle should not be washed in strong sunshine.
• If the vehicle is rinsed
with
a
hose,
do not direct the jet of water at the lock cylinders
- they can freeze up in the winter.

Washing
vehicle
with
high
pres­

sure
cleaner

• The operating instructions for the high
pressure
cleaner must be followed closely
- particularly
with
regard to pressure and working distance.
• Do not use a concentrated jet. • The water temperature must not be above 60 degrees C.

Attention

Tyres
must
never
be
cleaned
with
a
concentrated
jet! Even at a
rela­

tively
large
working
distance
and a
very
short
spraying
time,
dam­
age can occur.
Waxing

A
good coat of wax protects the .s~ : e
paintwork to a large extent against the e". -
ronmental influences listed under
"Wash­

ing"
on the previous page and even agars:
light
mechanical damage.
At the latest when water on the clean paint

does
not form small drops and roll off, the
vehicle should be protected by applying a
coat of good hard wax.
Even
when a wax solution is used regularly in the washing
water it is advisable to protect the paint
with

a
coat of hard wax at least twice a year.
Polishing

Should
only be done if paint has lost its shine
and gloss cannot be brought back
with
wax. If the polish used does not contain preserv­
ative compounds, the paint must oe waxed
afterwards.

Note

Matt
painted
and
plastic
parts
should not be treated
with
polish or hard wax..

Undercoating

The underside
of
the vehicle
is
coated with
a special compound
to
protect
it
from cor­ rosion and damage.
However,
as
this protective layer becomes
damagedwhen the vehicle is in use, the pro­
tective coating under
the
body and
on the
running gear should be examined at defined
intervals
-
preferably before
and
after
the

winter season
- and any
damage made
good.

Volkswagen dealers have stocks
of
the cor­ rect compound, have
the
necessary equip­
ment and
are
familiar with
the
application
procedure. We advise you therefore to have
the patching
up or
additional coating done by
a
Volkswagen dealer.
Note
for
vehicles
with
a
catalytic

converter

Due
to
the high temperatures which occur
in the afterburning process, additional heat
shields
are
fitted over
the
catalytic
con­

verter. Underbody sealant must
not be
applied
to
these shields,
the
catalytic
con­

verter
or
the exhaust pies. Removal
of the
heat shields
is
also
not
permissible.
Cavity preservation

All cavities
on the
vehicle which could
be
susceptible
to
corrosion
are
given perma­
nent protection
at
the factory.
This coating does not need checking or any subsequent treatment. Should
a
smal
amount of wax run out of the cavities at high
ambient temperatures
it can be
removec
with a plastic scraper and some white spirit

If the wax
which
has run out is

By
tinker­
ing
with
parts
which affect
the

safety
of a
motor
vehicle
one can

endanger
oneself
and
other road users.

Altering the engine settings is detrimental to the
exhaust

emissions.
This means
that
the envi­
ronment is burdened unnecessarily
and the
fuel
consumption
also
in­
creases.

The disposal of old oil, used brake

fluid,
dirty
coolant, defective
bat­

teries or worn-out tyres etc. must be
done according to environmental
protection regulations. It is even
better
if old operating fluids and parts are used
again
and
do not become a burden on the envi­
ronment. Through "recycling" valu­

able
raw-materials and
energy
are
saved and at the same
time
it re­ lieves the load on the toxic waste

dumps.
Volkswagen dealers collect
all reusable materials and parts and

passes
them
on to the correct

•
Switch off engine, remove ignition key.

•
Pull handbrake on firmly.

•
Move gear lever into neutral or
"P"
position.

•
Allow engine to cool off.

•
As long as the engine is at op­
erating temperature:

-
Do not put your hand into the radiator fan, it could switch on

suddenly.

-
Do not open the radiator cap be­
cause
the cooling system is

under
pressure.

•
Avoid causing short circuits in
the electrical system - particular­ ly at the
battery
-.
•
If tests have to be
carried
out

with
the engine running,
there
is
an additional danger
present

from rotating parts - e.g.
V-belts,
generator, radiator fan etc. - and
from the high voltage ignition
system.

Attention must be paid to the warnings given in this Instruc­
tion Manual and to the generally
applicable
safety regulations.
When topping up fluids one
should
ensure
that
they are not mistaken,

one
for the other, under any
circum­

stances,
otherwise serious
func­

tional defects
will
result.
So
that
leaks
are quickly de­
tected
the ground underneath
the vehicle should be checked
reg­

ularly.
If spots as caused by oil or

other
operating fluids can be seen, the vehicle should be
taken
to the
workshop for checking.
