Glow plug system

The
engine is
fitted
with
a glow plug
sys­
tem.
The required glow plug warm-up time
is
indicated by a lamp which is controlled by
the coolant temperature - see page 49.
Cold
starting
aid

To
assist cold starting, there is a device (cold starting aid)
fitted
in the injection
pump.

The
cold starting aid is actuated when the knob on the
left
of the steering column is

fully
pulled out.
Starting
a cold
engine

• At ambient temperatures down to -15
degrees
C, pull the cold start knob our

fully
before operating the starter.
At lower temperatures, the knob should not
be
pulled out
until
engine
is
firing
reg­
ularly
- the engine will then start more
readily.
• Turn the key in the ignition lock to
posi­
tion 2 (see page 36) - the glow plug warning lamp comes on. It goes out when the igni­
tion temperature is reached (see page 49).

While
the
glow
plugs are
working
do not
switch
on any
other
heavy
cur­

rent
consumers because
this
would

place an unnecessary load on the

battery.

• When the warning lamp goes out, start the engine immediately.

Do
not depress the accelerator while start­

ing.

If the engine only fires irregularly, continue
to operate the starter a few seconds longer (30 seconds at maximum) until the engine runs under its own power.
If the engine does not start, switch the glow
plugs on again and try starting it again as de­

scribed.
If the engine still does not start the
fuse for the glow plugs may have blown -
page123.
•
Push
the cold start aid knob in fully as

soon
as the engine has reached its normal
operating temperature.

Starting
a
warm
engine

The
glow plug lamp does not come on - the engine can be started straight away. Do not pull the cold start aid knob and do not press
the accelerator pedal.

Stopping engine
•
Applies to all engines: I*I"en engine has been running fast

•:'
a long time, let it idle for about
2 —inutes so
that
it can
cool
down
:
ghtly before being switched off.
Attention
After the engine has been

stopped
the fan can continue
running for a
while
(up to about 10 minutes)
with
the ignition
switched off. It can also
start
to
run again suddenly
after
a short

time
if

-
the coolant temperature in­
creases
due to
heat
build-up

-
when engine is hot and the en­ gine compartment is heated
additionally by strong
sun­
light.

Special
care must therefore be
taken when working in the en­ gine compartment.
•
Applicable to vehicles
with
cata­
lytic converter *:

The
ignition must not be switched off as long as the vehicle is rolling

with
a gear engaged, otherwise, un- burnt fuel can
pass
into the catalytic
converter and cause damage.

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.

Defrosting
windscreen
and side

windows

• Rotary switch A to stage 3
• All levers to the
right
• Vents 3 closed
• Adjust vents 4 so
that
additional warm air can be directed to the side windows.

Demisting
windscreen
and side

windows

When the windows mist up due to high air humidity, e.g. when it is raining, we recom­
mend the following settings:
• Rotary switch A to stage 2 or 3 • Lever C if necessary, to
right
into
heating range
• Lever D to
right

• Vents 3 closed
• Adjust vents 4 so
that
additional warm air
can
be directed to the side windows.

Heating
interior
quickly

• Rotary switch A to stage 3 • Lever C to
right

• Lever B to
left

• Vents 3 closed
• Vents 4 opened.
Heating
interior
comfortably

When the windows are clear and the de­ sired interior temperature has been re­

ached,
we recommend the following set­
tings:
• Rotary switch A to stage 1 or 2
• Lever C at the desired heat
output

• Levers B and D set to desired air distribu­ tion. If the windscreen once again becomes misted up, move levers B and D to the
right.

• Vents 3 closed
• With vents 4 the desired amount of warm air and the air flow direction can be set.

Ventilation
(fresh
air
operation)

With the following settings, unheated fresh air flows from vents 3 and 4:
• Rotary switch A to desired stage
• Lever B to
right
and lever D to
left
• Lever C fully to
left

• Vents 3 and 4 open If required, levers B and D can be set to
other positions.
Notes

• To ensure
that
the heating and ventila­
tion
can work properly, the air inlet in
front
of the windscreen should be kept free of
ice,
snow and
leaves.

• All controls except the rotary switch A
can
be set to any intermediate position,
• To prevent the windows from misting up the blower should be running slowly when driving at low
speeds.

• The heat
output
depends on the coolant temperature - the
full
heat
output
is there­
fore only available when the engine is warm.
• The stale air
escapes
through ventilation slots in the luggage compartment/loading

area
side panel trim. Therefore these slots should not be covered.

On
vehicles
with
a
full-width
partition and
on the Pick-up and Double Cab models the
stale air
escapes
through slots in the
front

doors.

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.

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.
