This
lamp flashes for a few seconds as a
functional check when ignition is switched
on.

If the lamp does not go out afterwards or

flashes
when driving, either the coolant
temperature is too high orthe coolant level1'
too low:
Stop,
switch
engine
off and check

level.
Add coolant if necessary.
11 Only on vehicles
with
automatic coolant level monitor(see page 102).
Attention

• Be
careful
when
opening the

coolant
expansion
tank!
When
the
engine
is hot the cooling
sys­

tem is
under
pressure -
Danger
of scalding!
Therefore
let
engine
cool
down
before
unscrewing

the cap.
• Do not
touch
the fan. The fan can
switch
on suddenly -
even

when
ignition
is
switched
off.

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.

Notes

Pools of
water
under
the
vehicle

• When the ambient temperature is high
and
the air very humid, condensed water

can
drip off the evaporator and form a puddle under the vehicle. This is quite nor­

mal
and does not indicate a leak.

Operating
faults

• Should the air conditioner not work at
any
time, either:
- the ambient temperature is below about + 5 degrees C,
- the fuse has blown.

Check
fuse and if necessary renew it - see

page
122. If the trouble is not due to
a
defec­
tive fuse, switch the system off and have it
checked.

- the air conditioner has switched off due to the coolant temperature being too high -
see
page 41
also.

• If the cooling
output
drops off, switch the
A/C
off and have the system
checked.
Using air
conditioner

economically
In cooling operation the air conditioner
com­

pressor
places demands on the engine and
therefore influences the fuel consumption.

To
keep the period switched on as short as
possible,
the following points should be

noted:

• If the inside temperature is very high after the vehicle has been parked in the sun, it is recommended to open doors or win­

dows
briefly to enable the hot air to
escape.

• The air conditioner should not be
switched
on during a journey if the windows

or
sliding/tilting
roof*
are open.
• If the desired interior temperature can be attained
without
switching on the air condi­
tioner, the fresh air operation should be se­
lected.
Recirculating
air
switch

If badly contaminated air is to be prevented
from entering the vehicle, e.g. when driving
through a tunnel, the recirculating air switch in the instrument panel can be
pressed.

When
the recirculating air system is
switched
on, a small warning lamp lights up in the switch.

However,
the recirculating air system

should
only be used for a short period other­

wise
the windows will mist up.

for 10 years. After this period the heat

exchanger
must be replaced by a Genuine heat exchanger in a Volkswagen Dealer­

ship.
To enable this period of time to be monitored the year when the heater is taken
into use is marked on the maker's plate on
the heater (under vehicle floor).

The
Volkswagen dealer enters the date of
replacement on the plate on the heater.

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.
