The following points are of particular import­
ance
to the safe operation of the brakes.
• New brake linings must also be run in and do not have the optimum
friction
prop­
erties during the
first
200 km. The slightly reduced braking effect can be compen­
sated for by more pressure on the brake

pedal.
This also applies when new linings have been fitted.
• If the brake pedal travel increases suddenly, it may be
that
one of the two
brake circuits has failed. You can still drive
on to the next Volkswagen dealer but be prepared to use more pressure on the pedal
and allow for longer braking distances on
the way.
• The brake
fluid
level must be checked regularly-see page 105.
The brake warning lamp
will
come on to indi­ cate
that
the brake
fluid
level is too low (see

also
page 48).
• Brake lining wear depends to a large ex­
tent
on the operating conditions and style of driving. On vehicles which are used mainly in
town
traffic
and stop/start conditions or
are driven hard it may be necessary to have
the thickness of the brake linings checked by a Volkswagen dealer in between the in­
tervals given in the Service Schedule.
• Change down in good time when driving downhill, in orderto make use of the engine braking effect. This relieves strain on the
brake system. When the brakes are applied do not keep them on con::rjc_s , =" .
and release alternately.
• Under certain operating conditions, *c example after driving through water, a^e' heavy rain or after washing the vehicle the
braking effect may be retarded by wet, or in
winter iced-up brake discs and linings - the brakes must be dried out
first
by applying
the footbrake.
The
full
braking effect may also be delayed when vehicle has been driven for some time
on heavily salted roads
without
using the
brakes,
because the layer of salt on discs
and pads has to be removed
first.

Attention
If a
front
spoiler,
full
size
wheel

trims
etc., is
retrofitted,
it is necessary to
ensure
that
the
flow

of air to the
front
brakes
is not re­

stricted
-
otherwise
the
brakes

can
overheat.

Starting
the
engine

General
hints
Attention

When
starting
the
engine
in con­

fined
spaces
there
is a
danger
of poisoning.
• Before starting, move gear lever to neu- ml
(with
automatic gearbox, selector lever -
"P"
or "N" position) and apply handbrake
I 'mly.
• On vehicles
with
a manual gearbox de-
:"9ss
the clutch pedal when operating

=:arter
so
that
starter only has to
turn
en­
gine.

• As soon as engine starts, release the gnition key so
that
starter can disengage.
• After starting a cold engine it may sound
_oisy
for a moment or two because the oil pressure has to build up in the hydraulic
tappets
first.
This is normal and no cause for
a
arm. Do not
warm
engine
up by run-
W>
ning
it
with
vehicle
stationary.
Drive
off
straight
away.

Do
not overrev or use
full
throttle
until the
engine has reached the normal operating
Temperature. • On vehicles
with
a
catalytic
con­

verter
the
engine
must
not be

started
by
towing
the
vehicle
in ex­

cess
of 50 m.
Otherwise
unburnt

fuel
can pass
into
the
converter
and
lead
to
damage.

•
Before
trying
to
start
engine
by
towing,
the
battery
from
another
ve­
hicle
should be used for
starting
if
possible - see
page
130.
Petrol
engines

These
engines are equipped
with
a cer: ~-
jection system
that
automatically s^c; es the correct fuel/air mixture at ail anc e~:
temperatures.

When
engine is cold or at
operating

temperature
do not accelerate before or
during the starting procedure.
Applicable to all engines:
If the engine does not start at once, stop

using
the starter after 10
sees,
wait about
half a minute and then try again. If the engine still does not start, the electric
fuel pump fuse may have blown - see page
122.

When
the engine is
very
hot it may be
necessary
to accelerate slightly after the
engine has started.

For
further details see pages 102 and 103.
If the coolant level is in order the trouble
may be due to failure of the radiator fan.

Check
radiator fan fuse and renew if
necessary-seepage
122.
If the warning lamp does not go out al­
though coolant level and fan fuse are in order, do not
drive
on - call in expert as­

sistance.

If the trouble is only caused by the fan and

assuming
coolant level is in order and tem­ perature warning lamp is out - one can drive
on to the nearest Volkswagen dealer. In
order to make good use of the air stream for

cooling,
do not let engine idle or drive very
slowly.

If the warning lamp does not go out or

flashes
when driving - a buzzer also sounds
at engine speeds above 2000 rpm - stop,
switch
engine
off, check oil level and if
necessary,
add oil - see page 97.
If the lamp comes on although the oil level

DRIVING
TIPS

The technical
prerequisites

"or
a low fuel consumption and efficiency were "built in" at the factory. Particular im­
portance was placed on the lowest possible

disturbance
to the environment. To retain

and
make the best possible use of these
characteristics
attention should be paid to
the following points:

Vehicles
fitted
with
a
catalytic

converter
may
only
be
driven
on

unleaded
petrol.

Even
those
vehicles
which
do
not
have
a
catalytic
converter

should
be
driven
on
unleaded
petrol
for the
sake
of the
environment.

The
prescribed
maintenance

operations
should
be
carried
out

exactly
as
specified
in the
Service
Schedule - see
also
page
93.
Having your vehicle regularly serviced by
a Volkswagen dealer not
only
ensures
that
it is always operationally fit, but it
also ensures economy, lowest possible burden on the environment and a long
service
life.
Check the
tyre
pressures
every
4

weeks.

Low
tyre
pressures increase the rolling

resistance.
This not
only
increases the

fuel
consumption and
tyre
wear,
but the
handling is also impaired.
Do not
carry
unnecessary
ballast

in the
luggage
boot

Particularly in
town
traffic
when one has to accelerate
often,
weight
has a
great
in­
fluence on the
fuel
consumption. As a

rule
of
thumb:
For every 100 kg of
weight

the consumption increases by approxi­
mately
litre
per 100 km.

Remove
roof
rack
immediately

after
use
Particularly at
high
speeds the increased
air resistance makes
itself
felt
consider­

ably.

gCK
Electrical
consumers
should
only
be
switched
on
when
they

are
actually
required

Heated rear windows, additional driving

lights
and heater blower consume a con­
siderable amount of
current.
The higher
alternator
load
also increases the
fuel

consumption. For instance, over a period of 10 hours, the heated rear window
will

increase
the
fuel
consumption by ap­
proximately 1
litre.
Check the
fuel
consumption
reg­

ularly

The
fuel
consumption should be checked
each
time
the
tank
is
filled
up. By doing
this
inconsistencies on the vehicle which
lead to an increased
fuel
consumption
can be discovered sooner.
• Check the
engine
oil
level
each
time
the
tank
is
filled
up

The
oil consumption depends to a great ex­

tent
on the engine load and
speed.
Depend­
ing on the style of driving the consumption

can
be as much as 1.0 litres/1000 km.
It is normal for the oil consumption of a new

engine
to reach its lowest level after a cer­
tain mileage has been covered. The
con­
sumption cannot be properly
assessed
until
the vehicle has run approx. 5000 km.

This
also
applies to the fuel consumption
and
the engine output.

•
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.

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.

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.
