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.

GENERAL
MAINTENANCE

Wheels

General
notes

• New tyres do not give maximum grip straight away and should therefore be run in
at moderate speeds and a careful style of
driving for about the
first
100 km. This will help to make the tyres last longer.
• Check tyres for damage from time to time (cuts, splits, cracks and lumps) and re­move any foreign bodies embedded in the
treads.
• To avoid damage to tyres and wheels crive over curbs and similar obstacles very
slowly and as nearly at
right
angles as
poss­
ible.
Damage
to wheels and tyres is not always

easy
to see, so if you
think
that
a wheel is
damaged,
it must be checked by a Volks­
wagen dealer.
• Keep grease, oil and fuel off the tyres.
• Replace missing dust caps as soon as
possible.

• Mark wheels before taking them off so
that
they rotate in the same direction when put back on again. • When taken off, the tyres should be
stored in a
cool,
dry and preferably dark
place.

Tyres
which are not on wheels should be stored in a vertical position.

Tyre
life

Tyre life depends to a considerable extent on the following factors:

Inflation
pressure
The inflation pressure is very important par­
ticularly at high
speeds.
Therefore, the pres­
sures
should be checked at least once a month and before every long journey.
At this opportunity do not forget the spare

wheel:

• The spare wheel should always be in­ flated to the highest pressure required on
the vehicle.
Always
check the pressures when the tyres are cold.
When
warm,
the pressure is
higher
but do not
reduce.
The pressur­

es
are given on page 147 and on a sticker on
the driver's door lock pillar.
Pressures
which are too high or too low
shorten
tyre
life - quite apart from the detri­ mental influence on vehicle handling.

Attention

At
continuous
high
speeds a
tyre
in
which
the pressure is too low

flexes
more
and
heats
up excess­
ively.
This can cause
tread
separ­

ation
and
tyre
blow
out.

pCU
A
pressure
which
is too low in- oo
creases
the
fuel
consumption

and
this
burdens
the
environment
unnecessarily.

Mode
of
driving
Fast
cornering, hard acceleration and viol­
ent braking also increase
tyre
wear.

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.

DO-IT-YOURSELF
- Wind jack arm up by turning the crank handle
until
the jack
just
goes under the

vehicle.

- The claw of the jack must fit round the vertical rib on the side member so
that

the jack cannot slip when vehicle is
lifted

- see illustration.
- If the ground is soft, place a large strong
piece
of packing under the jack base
plate.
- Align jack and at same time wind claw up
further
until
it contacts the vertical rib on
side
member. •
Lift
vehicle
until
the defective wheel is

clear
of ground.
• Remove wheel bolts and place them on
a
clean surface (hub cap, cloth, paper) next
to the jack and take the wheel off.
• Fit spare wheel and lightly tighten all bolts. The wheel bolts must be clean and

easy
to
turn
- do not under any circum­

stances
use grease or oil!
• Lowervehicleand fully tighten bolts indi- agonal sequence.
• Refit the wheel trim.
•
Place
defective wheel in spare wheel carrier and secure it - see page 119.

Notes

• Pay attention to the following after changing a wheel:
- Check the
tyre
pressure immediately on the spare wheel which has been fitted.
- Have the tightening torque of the wheel bolts checked
with
a torque wrench as

soon
as possible. The torque for steel
and alloy wheels is 160 Nm. If it has been established when changing
the wheel
that
wheel bolts are corroded and hard to screw in, they must be renewed be­
fore checking the tightening torque.
Until these checks have been carried out
one should, for safety reasons, only drive at

a
moderate
speed.

• The defective wheel should be repaired
as
soon as possible.

Attention
If the
vehicle
is to be
subsequent­
ly
fitted
with
wheels
or
tyres

which
differ
from
those
fitted
by
the
factory,
it is
essential
to
read

the
remarks
in the
centre
and
right
hand
columns on
page
113.
