Air conditioner*
-'le air conditioner is available as a normal :r fu lly automatic system (Climatronic*)
'le air conditioner in both cases is a com­
u ne d cooling and heating system which
c " ers maximum comfort at all seasons of "18 year.

h e air conditioner
works only when the en­
gine is running, the ambient temperature is
,:move about + 5°C and the blower speed is
cetween 1 and 4.

. 'hen air conditione r is switched on it re­
d uc es not only the temperature inside the
. e hicle but also the air humidity When the .ambient air humidity is high this not only
a kes the vehicle occupants feel more
_ o m fortable but also prevents the
windows
c ~rom steaming up.
Ni th
the Climatronic* the selected ve­Icle interior temperature is maintained fully
a u tomatically. This is done by automatically
. I a rying the temperature of the air from the "e nts, the blower speed (air volume) and meair distribution.
Notes
• The operation of the normal air conditioner* is described on pages 59 -61. • The differences for the Climatronic* are given on pages 62 and 63.
Controls
Rotary switch A -Blower and air supply and air conditioner cut-off
The air flow can be regulated in four stages.
In position 0, the blower and air conditioner
are switched off. If contaminated air should
be prevented from entering the vehicle in­
terior, button E (air recirculation) should be
pressed.
On vehicles
with a fresh airfilter' this is only
necessary for a gas type pollution. Dust,
pollen etc. will be held back by the filter.

• Select air recirculation by pressing but­

ton E

• Vents 3 and 4 open.

In this mod e, air is drawn from inside the ve­

hicle and cooled (air recircu lation) The air
recirculation mode should not be se­lected for long periods of time as no fresh air is then supplied.
Note
Smoking should be avoided w hen air recir­
culation is selected , as the smoke drawn in from the vehicle interior deposits on the
evaporator of the air conditioner. This leads
to permanent odours when the air condi­
tioner is i n operation. These can only be
eliminated by exchanging the evaporator,
which is time-consuming and expensive.
Normal cooling
• Switch air condit ioner on by pressing
button 0
• Rotary
switch A to stage 1 -4 as re­
quired.
• Rotary regula
tor B to the desired air tem­perature (so that heating is also possible)
• Rotary regulator C to desired position

The automatic regulation of the sys­tem can be influenced by the but­tons 9 -14.
Recommended standard setting for

all times of the year:

Temperature about 22 degrees C (72
degrees F) and AUTO button.

With this setting a pleasant climate in the
vehicle is reached most quickly
This setting should therefore only be alt ered
when required for personal comfort.
Using the system
When ignition has been swi tc hed on the
system normally works in the Automatic
mode. Items 1, 2, 6 and 7 appear in the dis­play.
The Clim atronic maintains the selected ve­hicle interior temperature fully automati­
cally.
To do this temperature of the air flow as well as the blower speed (air volume) and air dis­
tribution are altered automat ically.
If the settings deviate d fr om Automatic
operation before the ignition is switched off
the selected functions are stored for one hour. If ignition is switched on again later the
system works in the Automatic mode.
The layout of the air vents is show n on page 60.

r Notes on Automatic mode
• The interior temperature can be freely
s e lected w ith buttons 16 and 17 and is S ored alw ays until another temperature is selected , -he interior temperature can be set be­
-we an + 18°C (64°F) and + 29°C (86°F) In th iS range it is automatically regulated,
f tempe ratures below 18°C are selected
LO" appears in the display , With tempera­
-res abo ve 29 °C (86 ° Fl. "HI " is displayed ,
., these two end positions the system
N or ks continuous ly at ma ximum cooling or
n eating output. The temperatu re is not
r egulated
•
In certain operating con ditions it may be fo und that the syste m temporarily carries
o ut functions which are not quite as ex­
5-pe cted, This includes, for examp le, that for
a few seconds after sta rting from cold, air is directed mainly into the fo ot wel l. This is ntentional so that damp air in the sys tem
d oes not cause the windo ws to mist up ,
Deviating from Automatic mode
In nearly all cases the Automatic mode
offers the best conditions for the comfort of
the vehicle occupants all the year round,
I n isolated cases however it might
be necessary to deviate from some functions
of Automatic mode by pressing certain but­
tons, The Climatronic still works fu lly auto­
matically
• With buttons 9 and 10 the blo w er speed
and thus the air vo lume can be increased or
r educed, Th is is sho wn by a change in the
number of lin es in display field 1
• With
bu tton 11 the de-humidifying and defrosting effect for the windsc reen can be
increased if, for example persons w ith
damp clothing
are picked-up shortly after
moving off,
• W ith button
12 air recircu lation can be
se lected to pre vent for examp le dust or
st rong smells
from entering the vehicle in­
terio
r. At ambient temperatures below 5cC the sy ste m auto mat icall y sw itches off, This can lead to the window misting u p as t he air is no longer de-humidi­fied.
Note
Smoking should be avoided when air recir­culation is selected as t h e smoke drawn in from the vehicle interior deposits on the
evaporator of the air conditioner, This leads
to permanent odours when the air condition
is in operation These can only be efiminated b
y e xchanging the evaporator, which is
time-consuming
and expensive.
• With buttons
13 and 14 the air flow can
be to the upper part of the body or into the
footwe ll,
The air distribution buttons 11, 13 and 14
can be used in combination ,

• With button
18 (OFF) the complete sys­

tem is sw itched off, This button should only

be pre ssed in isol ated cases eg when

the re is a fault in the system .

Wh en th e sp ecial functions are no longer re­
quired the Automatic mode should be

s w itch ed on again without delay by pres­

sin g the AUTO button,

Operating instructions
• Ensure that the sensor betvveen the
windscreen defrost outlets in the centre of
the instrument panel and the air grille next
to the radio is not covered.
• If, after switching on the ignition,
all sym­
bols in the display area flash for about 15
seconds, there is a fault in the system -con­
tact a Volkswagen dealer.
Notes for both air conditioning
systems
• To ensure that the heating, ventilation
and air conditioner can work properly, the air
inlet in front of the windscreen should be
kept free of ice, snow and leaves.
• The heat output depends
on the coolant
temperature -the full heat output is there­
fore available when the engine IS warm.
• The stale air escapes through openings
in the luggage compartment side panels.
Therefore when loading the luggage com­
partment ensure that the openings are not
covered .
• 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.
Notes for the normal air condi­
tioner
• All controls except the rotar y switch A and buttons 0 and E can be set to any inter­
mediate position.
•
To prevent the windows from misting up
the blower should be running slowly when driving at low speeds.
Using air conditioners economi­
cally
In cooling operation the air conditioner com­
pressor places demands on the engine and
therefo re influences the fuel consumption.
To keep the period switched on as short as possible, the following points should be
noted:
• If the
in side temperature is very high
after the car has been parked in the sun, it is recommended to open doors or windows 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 w ithout switching on the air
cond itioner the fresh air operation should
be selected (does not apply to Climatronicl.
Operating faults
• Should the air cond i:ioner not work at
any time, either .
- the ambient temperatu re IS below about +5 °C,
-or the fuse has blown.

Check fuse and if necessary r
enew it - see

page 119. If the troub le is n ot due to a defec­

tive fuse, SWitch the system off and have It
checked.

- the air conditioner
has svvitched off due

to coolant temperature being too high -see
page 45.
• If the cooling output drops off, switch
the AlC
off and have the system checked.
