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.

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.

'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.

Windscreen
washer
system
"he fluid container is on the
right
of the en­ gine compartment. The container holds
about 5 litres, on vehicles
with
headlight
washer
system* about 7 litres.

The
rear window washer is supplied
with
fluid from the container in the engine com-oartment. Filling the
container

Pull
the cap off and
fill
container to the brim

with
washer fluid.
Press
cap on
tightly
again,
then switch on ignition and check
operation of washer system.
It is advisable to add a window cleaning
sol­

ution
with
a wax remover
(with
anti-freeze
additive in winter) to the water because plain water is not usually sufficient to clean
the glass and headlight lenses quickly and
thoroughly. The mixing ratios on the win­ dow cleaner packaging must be adhered to.

Even
when
heated
windscreen

washer
jets*
are fitted, a window clean­ ing solution containing anti-freeze should

be
added to the water in the winter.

Note

If at any time no window cleaning solution

with
anti-freeze additive is available, methylated spirits can be
used.
Do not,
under any circumstances, add engine
cool­

ing system fluid or other additives.
Adjusting
washer
jets

When
the vehicle is stationary, the water
should
hit the windscreen approximately as

shown.

The
jet for the rear window washer is in the
wiper shaft. The water jet should hit the
glass
in the centre of the wiped area.

The
jets can be adjusted
with
a needle.

The
jets for the
headlight
washer
sys­
tem*
can only be adjusted
with
a specia

tool.
When adjustment is necessary,
con­

tact your Volkswagen dealer.

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.

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

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.

Tow
starting/towing

General
notes

• "owing eyes are provided on the
right
under
front
and rear bumpers.

Tow-ropes
or bars should be attached at

these
points only.

On
vehicles
with
a factory
fitted
towing bracket a towing eye is not fitted. On those

vehicles
the towing bracket can be used for
towing.
• The tow-rope should be slightly elastic to reduce the risk of damage to both ve­
hicles.
It is advisable to use synthetic fibre

ropes,
or ropes of similar elastic material. It
is
however
safer
to use a
tow-bar!

Avoid
excessive towing
effort
and do not

jerk.
During towing operations on other than
surfaced
roads there is always the danger

that
the attachment points will be over­
loaded
and damaged.
•
Before
trying
to
start
engine
by
towing,
the
battery
from
another
ve­
hicle
should be used for
starting
if
possible - see previous page. If the
vehicle
has to be tow
started

or
towed
at any
time,
the
following

must
be noted:
•
Check
whether there are any local traffic regulations concerning the towing of ve­

hicles.

• Both drivers must be familiar
with
tow­ ing procedures. Inexperienced drivers

should
not attempt to tow start or tow.
• When using a tow-rope the driver of the towing vehicle must engage the clutch very gently when moving off and changing gear.
• The driver of the vehicle being towed must ensure
that
the tow-rope is always

taut.
• The emergency lights must be switchec
on on both vehicles - unless local regula­
tions differ.
• Turn ignition key to "Drive" position sc
that
the steering wheel is free and the
turr
signals,
horn, and, if necessary, the wind­

screen
wiper and washer can be
used.

• As the brake servo only works when the engine is running, considerably more pres­

sure
is required on the brake pedal when the
engine is not running.
• On vehicles
with
power assisted steer­ ing more force is required to
turn
steering
wheel when engine is not running.
• When there is no lubricant in the manua or automatic gearbox, the vehicle may only

be
towed
with
driving wheels lifted.
