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.

Air
conditioner*
in cab

Description

T".e air conditioner is a combined cooling srd heating system which provides the
r-aximum possible comfort all the year
rcjnd.

Tpe air conditioner works only when the en-

pie
is running and the ambient tempera- t.re is above about + 5 degrees C.
,ien air conditioner is switched on it re-
bjces not only the temperature inside the
•
ehicle but also the air humidity. When the

=-nbient
air humidity is high this not only
Iakes
the vehicle occupants feel more
comfortable but also prevents the windows
""Dm
misting up.
~ne cooling system works best when all the
v.indows are closed.

instructions

Defrosting
windscreen
and side

windows

• Move upper lever to position ES .
• Move lower lever fully to the
right.

• Set blower switch to stage ES , •
Close
centre outlets.
• Direct side outlets to side windows.
• For optimum defrosting of the wind­
screen
the side outlets should also be

closed.

Demisting
windscreen
and side

windows

• Move upper lever to position ES . For very effective demisting of the windows,
the cooling system switches in automati­

cally
from about + 5° C ambient tempera­
ture.
• Move the lower lever into the heating
range
at low ambient temperatures, and at
high temperatures and high air humidity
(tropics) into the cooling range.
• Set blower switch to stage El or 4 .
•
Close
centre outlets.
• Direct side outlets towards side win­
dows.

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.

when driving through a tunnel.
Recirculating air operation should only be

Additional
heater*

With the additional heater the rear seating
area
can also be comfortably heated.
Its blower can be switched on
with
a three

stage
rotary switch in the dash panel
(left
hand illustration).
Temperature regulation is carried out to­ gether
with
the temperature regulation of
the normal heater - see page 55 .
On
vehicles
with
an airconditionertempera-
ture regulation forthe additional heater is by way of a rotary control on the
right
adjacent
to the blower switch (centre illustration).

Clockwise
- increased heat output

Anti-clockwise
- decreased heat output
On
vehicles
with
seating arrangement the
outlet is located under the centre row of
seats.
This outlet can be closed by pushing it in.

On
the Delivery van, Multivan and Camper
the outlet is located behind the
