Operation
Dust and pollen filter
The dust and poll
en filter with its activated
charcoal cartridge serves as a barrier
against impurities in the air taken into the ve-
hicle interior.
The dust and pollen filter must be changed
regularly so that air conditioner performance
is not adversely affected.
If the filter loses efficiency prematurely due to
use in areas with very high levels of air pollu-
tion, the filter must be changed more fre-
quently than stated in the Service Schedule.
WARNING
Reduced visibility through the windows in-
cr
eases the risk of serious accidents.
Always ensure that all windows are free
of ice and snow, and that they are not fog-
ged, so as to maintain good visibility of ev-
erything outside.
Only drive when you have good visibility.
Always ensure that you use the air condi-
tioner and heated rear window to maintain
good visibility.
Never leave the air recirculation on for a
long period of time. If the cooling 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
r
educe driver concentration possibly re-
sulting in a serious accident.
Never leave the fresh air fan turned off or
use the air recirculation for long periods of
time; the air in the vehicle interior will not
be refreshed.
CAUTION
T
o replace the pollen filter, always visit a
service centre.
Switch the air conditioner off if you think
it may be broken. This will avoid additional
damage. Have the air conditioner checked
by a specialised workshop.
Repairs to the air conditioner require spe-
cialist knowledge and special tools. SEAT
recommends visiting a SEAT Official Serv-
ice.
Note
When the cooling syst
em is turned off, air
coming from the outside will not be dried.
To prevent fogging of the windows, SEAT
recommends leaving the cooling system
(compressor) turned on. To do this, press
the function button . The icon should
light up.
The maximum heat output required to de-
frost windows as quickly as possible is only
available when the engine has reached its
normal running t
emperature.
Keep the air intake slots in front of the
windscreen free of snow, ice and leaves to
ensure heating and cooling are not im-
paired, and to prevent the windows from
misting over.
The air from the vents flows through the
vehicle interior and is extracted by slots in
the luggage compartment designed for this
purpose. Therefore, you should avoid ob-
structing these slots with any kind of ob-
ject.
Do not smoke while air recirculation
mode is on, as smoke drawn into the air
conditioning system leaves residue on the
evaporator, producing a permanent un-
pleasant odour.
It is advisable to turn on the air condition-
ing at least 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.
When the engine is under extreme strain,
switch off the compressor for a moment.
