Pollution filter
The pollution filter (a combined particulate
filter and active carbon filter) serves as a bar-
rier against impurities in the outside air, in-
cluding dust and pollen.
For the climate control system to work with
maximum efficiency, the pollution filter must
be replaced at the specified intervals in the
Maintenance Programme.
If the filter loses efficiency prematurely due
to use in areas reaching very high pollution
levels, the pollen filter must be changed
more frequently than stated in the Service
Schedule. WARNING
Reduced visibility through the windows in-
cre a

ses the risk of serious accidents.
● Always ensure that all windows are free of
ice and snow
, and that they are not fogged, so as to maintain good visibility of everything
outside.
●
The m ax

imum heat output required to de-
frost
windows as quickly as possible is only
available when the engine has reached its
normal running temperature. Only drive when
you have good visibility.
● Always ensure that you use the heating
system, fr
esh air system, air conditioner and
the heated rear window to maintain good visi-
bility to the outside.
● Never leave the air recirculation on for a
long period of time. If the c
ooling system is
switched off and air recirculation mode
switched on, the windows can mist over very
quickly, considerably limiting visibility.
● Switch air recirculation mode off when it is
not required. WARNING
Stuffy or used air will increase fatigue and re-
duce driver c onc

entration possibly resulting
in a serious accident.
● Never leave the fresh air fan turned off or
use the air recir
culation for long periods of
time; the air in the vehicle interior will not be
refreshed. CAUTION
● If y ou s

uspect that the air conditioner is
damaged, switch it off with the A/C button to prevent further damage and have it checked
by a s
pec

ialised workshop.
● Repairs to the air conditioner require spe-
ciali
st knowledge and special tools. There-
fore, we recommend you to take the vehicle
to a specialised workshop. Note
● If the humidity and t emper

ature outside the
vehicle are high, condensation can drip off
the evaporator in the cooling system and
form a pool underneath the vehicle. This is
normal and does not indicate a leak.
● Keep the air intake slots in front of the
windsc
reen free of snow, ice and leaves to en-
sure heating and cooling are not impaired,
and to prevent the windows from misting
over.
● The air from the vents flows through the ve-
hicle interior and i
s extracted by slots in the
luggage compartment designed for this pur-
pose. Therefore, you should avoid obstruct-
ing these slots with any kind of object.
● The air conditioner operates most effective-
ly with the windo
ws and the sliding/tilting
sunroof* closed. However, if the temperature
inside the vehicle is excessive because of the
sun, the air inside can be cooled faster by
opening the windows for a short time.
● Do not smoke while air recirculation mode
is on, as
smoke drawn into the air condition-
ing system leaves residue on the evaporator,
producing a permanent unpleasant odour. 140

Air conditioning
●
At low out s
ide temperatures, the compres-
sor switches off automatically and cannot be
switched on even with the AUTO button.
● It is advisable to turn on the air condition-
ing at l e

ast once a month, to lubricate the
system gaskets and prevent leaks. If a de-
crease in the cooling capacity is detected, a
Technical Service should be consulted to
check the system.
● To ensure correct operation, the grilles on
both sides of
the screen must not be obstruc-
ted ●
When the engine is u

nder extreme strain,
switch off the compressor for a moment. Economic use of the air conditioning
When the air conditioning is switched on, the
compre
s

sor consumes engine power and has
influence on fuel consumption. Consider the
following points in order to have the system
operating in the minimum possible time. ●
If the v ehic

le interior has overheated due to
an excessive solar radiation, it is best to
open the windows or doors to allow the hot
air to escape.
● While in motion, the air conditioning
should not be sw
itched on if the windows or
the sunroof* are open.

Air conditioning
Heating
M ax
imum he at
output, which is needed to
defrost the windows quickly, is only available
when the engine has reached its operating
temperature.
Coolant system
When the air conditioning is switched on, the
temperature and the air humidity go down.
This way, if the outside humidity is extreme,
the air conditioning prevents the misting of
the windows and therefore, comfort is im-
proved.
If the air conditioning does not work, this
may be due to the following reasons:
● The engine is stationary.
● The fan blower is switched off.
● The outside temperature is lower than ap-
proxim
ately +3 °C (+37 °F).
● The air conditioning system compressor
has been t
emporarily switched off because of
an increased engine coolant temperature.
● The air conditioner fuse is faulty.
● Another fault in the vehicle. Have the air
conditioning chec
ked by a specialised work-
shop. Air recirculation
 Air recirculation prevents unpleasant smells,
e.g. when pa
s

sing through a tunnel or in
queuing traffic, from entering the interior.
If the rotary switch C

thaw position, the recirculation flap will al-
ways be open (button light off).
If the rotary switch C is switched from any
position t o the th

will be automatically deactivated.

Disconnecting the recirculation
In any position of rotary switch C except
th a

● Pr e

ss button D again and the button's
l amp w
il

l go off, indicating that air recircula-
tion from the outside has been activated. In the thaw position of rotary switch
C , the
entr y
of air int

o the vehicle interior is always
from the outside. WARNING
In air recirculation mode, no cold air from the
outside ent er

s the vehicle interior. If the air
conditioner is switched off, the windows can
quickly mist over. Therefore, never leave the
air recirculation mode switched on for a long
time (risk of accident). Note
● When engagin g r

everse gear, the air recir-
culation is connected automatically to pre-
vent the entrance of exhaust gases in the ve-
hicle on travelling backwards. The control
lamp on the button  does not light up.
● If the temperature control is turned to the
col de

st setting (blue point) and the A/C but-
ton is on, the
“Air recirculation” function is
automatically activated in order to cool the
vehicle faster using less energy, and its func-
tion control lamp will light up.
● If the function is not deactivated by press-
ing the button, it
will deactivate after approx-
imately 20 minutes. 145

Adjusting the temperature ●
When you switch on the ignition, control 1 ›››
Fig. 167 can be used t o set
the required in-
terior temperature.
It is possible to select interior temperatures
from +16 °C (+64 °F) to +29 °C (+84 °F). In
this range the temperature is regulated auto-
matically. If a temperature below +16 °C
(+64 °F) is selected, “LO” is displayed on the
screen. If a temperature above +29 °C
(+84 °F) is selected, “HI” is displayed on the
screen. At both extremes, Climatronic works
at maximum cooling or heating power, re-
spectively. The temperature is not regulated.
In the event of prolonged, irregular distribu-
tion of the air flow from the outlets (particu-
larly the footwells) and significant differen-
ces in temperature, e.g. on leaving the vehi-
cle, sensitive people may catch cold. Air recirculation Air recirculation prevents unpleasant smells,

children or disabled people are left alone in
the vehicle. They could accidentally start the
engine or work electrical equipment such as
the electric windows, resulting in an acci-
dent. ●
Unsuper v

The engine can only be started using a genu-
ine SEAT key with its correct code.
If the following message* is shown on the in-
strument panel display: SAFE, the vehicle
cannot be started.
The engine can, however, be started if the
appropriate coded SEAT genuine key is used.
