WARNING  
Air conditioning  
When the air conditioning is switched on, the  
compressor consumes engine power and has  
influence on fuel consumption.  
Reduced visibility through the windows in-  
creases the risk of serious accidents.

cooling  
Always ensure that all windows are free of  
The air conditioner operates most e„ectively

long period of time. If the cooling system  
is switched oꢀ and air recirculation mode  
switched on, the windows can mist over very  
quickly, considerably limiting visibility.  
The manual air conditioning system heats,  
cools and dehumidifies the air.  
The Climatronic is an automatic air condi-  
tioner that heats, cools and dehumidifies the  
air.  
The dust and pollen filter must be changed reg-  
ularly so that air conditioner performance is not  
adversely a„ected.  
Switch air recirculation mode oꢀ when it is  
not required.  
With the Climatronic’s automatic mode it is  
possible to automatically regulate the air tem-  
perature, distribution and flow to achieve opti-  
mal thermal comfort.  
If the filter loses eciency prematurely due to  
use in areas with very high levels of air pollu-  
tion, the filter must be changed more frequently  
than stated in the Service Schedule.  
NOTICE  
Food, medicines and other objects sensitive  
to heat or cold may be damaged or made  
unsuitable for use by the air coming from the  
vents.  
To switch a specific function on, press the ap-  
propriate button. Press the button again to  
switch the function.

Heating,ventilationand cooling  
Note  
When the cooling system is turned oꢀ, air  
coming from the outside will not be dried. To  
prevent fogging of the windows, SEAT recom-  
mends leaving the cooling system turned on.  
To do this, press the function button

The maximum heat output required to de-  
frost windows as quickly as possible is only  
available when the engine has reached its  
normal running temperature.  
Keep the air intake slots in front of the  
windscreen free of snow, ice and leaves to  
ensure 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 is 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.  
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 oꢀ the compressor for a moment.

The defrost/demisting function removes  
ice and fog from the windscreen. The air

Air distribution  
The airflow adjusts automatically for comfort. It  
can also be manually distributed to the desired  
zone by pressing the corresponding button:  
The heated rear window only works when  
the engine is running and switches o„

NOTICE  
Air recirculation  
In vehicles with an air conditioner, do not  
smoke when air recirculation is switched on.  
The smoke may be deposited on the cool-  
ing evaporator and on the active combina-  
tion filter and cause permanent unpleasant  
odours.  
Air recirculation mode prevents the ambient air  
from entering the interior.  
Do not switch the seat heating on if any of the  
following conditions are met:  
When the outside temperature is very high, you  
can select air recirculation for a short period of  
time to refresh the vehicle interior more quickly.  
The seat is occupied by a person with limited  
perception of pain or temperature.  
The seat is not occupied.  
For safety reasons, air recirculation is switched  
in the following situations:  
The seat has a cover.

The windows are misted up  
WARNING  
For the sake of the environment  
Windows mist up when they are cooler than  
the ambient temperature and the air is very  
damp. Cold air can absorb less moisture than  
hot air, so the windows mist up more often in  
cold weather.  
If the fabric of the cushion is wet, this can  
adversely aꢀect the operation of the seat  
heating, increasing the risk of burns.  
The seat heating should remain on only when  
needed. Otherwise, it is unnecessary energy  
consumption.  
Make sure the seat cushion is dry prior to  
using the seat heater.
