DRIVING
TIPS

Driving
safely
Attention

The
operational
condition of your
vehicle
is
essential
to
safe

driving.
Therefore before moving off, always check
the following points:
• Lights and
turn
signals
•
Mirror
settings
• Cleanliness of
headlights,
lenses and
windows

Also
check at regular intervals, preferably
when filling the tank, all the checks listed on
page160

Furthermore compliance
with
the specified Inspection intervals - in particular the brake
fluid changing - is of great importance for operational safety - pages 93 and 98.
Attention

Safety
on the
road
depends to a

large
extent
on the personal
atti­

tude
and
style
of driving.

To
be on the safe side you should:
•
Always
put
seat
belt
on
before
moving
off -
even
in
town
traffic
-

and

• Ensure
that
all your passengers - including
those
on the
rear
seat
- are

wearing
their
belts
correctly
- page
15

Passengers
without seat belts can en­

danger
not only themselves, but also the
driver.
•
Adjust
head
rests
to body size.
The
upper edge of headrest must be ap­proximately at eye
level.

• Ensure
that
no
articles
interfere
with
operation
of pedals - page 29
•
Stow
all
luggage
correctly:
- in
boot
- page 28
- on the shelves - page 27
- on the
roof
- page 75 • Do not
drive
when
you
feel
tired.

Stop
for a break at the latest after driving for
two hours.
•
Never
drive
when
your
reactions
are
impaired
in any way. Not only alcohol but also drugs and many

medicines
can be very detrimental to your

reactions.

•
Adapt
vehicle
speed to
traffic
and
road
conditions.
Remember
that
particularly on smooth slip­
pery roads the handling and braking is li­
mited by the adhesion of the tyres. On wet

roads
the
front
wheels can aquaplane at
high
speeds.
The vehicle can then no longer

be
steered and braked properly.
•
Strictly
adhere
to the
traffic
regu­
lations
-
particularly
the speed li­

mits
-.
Further instructions on safety are given in
the various chapters in this manual.

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.

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.

Driving
in
winter

When
using summer Diesel trouble may be
experienced
at temperatures below 0 de­

grees
C because the fuel thickens due to

wax
separation.

Br
this
reason,
winter
Diesel
which is more

"esistant
to cold is sold during the winter in

Germany,
and this works satisfactorily
:Dwn
to between -15 and -22 degrees C,

cepending
on the type of fuel
used.

I countries with different climatic condi-
" :ns the Diesel fuels offered have a differ­

ent
temperature characteristic.
Check
with ; kswagen dealers or filling stations in the
::
jntry
concerned regarding the character-
s:
cs of Diesel fuels.
Filter
preheating

The
vehicle is
fitted
with a filter preheater.

This
will ensure, that the fuel system re­
mains
operational down to about - 25 de­

grees
C provided that winter Diesel which
is
cold resistant down to - 15
degrees
C is
used.
Diluting with petrol is then no longer
necessary
under these conditions.
If, at temperatures below - 25 degrees C
the fuel is waxed to such an extent that the
engine
will not start it is sufficient to place
the vehicle in a warm room for a while.
Fuel
additives
(anti-waxing agents and

similar
fluids) must not be mixed with the

out in a
workshop
or
filling
station.

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

QCK
If the wax
which
has run out is
<35 removed with clean
petrol,
heed
the environmental protection

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
