Air conditioning

WARNING

Reduced visibility through the windows in-

creases the risk of serious accidents.

CAUTION

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.

Air conditioning

●

Heating, ventilation and

cooling

●

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.

●

Repairs to the air conditioner require spe-

cialist knowledge and special tools. SEAT

recommends visiting a SEAT Official Serv-

ice.

●

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.

Dust and pollen filter

●

Switch air recirculation mode off when it

is not required.

The dust and pollen filter with its activated

charcoal cartridge serves as a barrier

against impurities in the air taken into the ve-

hicle interior.

●

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.

WARNING

Stuffy or used air will increase fatigue and

reduce driver concentration possibly re-

sulting in a serious accident.

The dust and pollen filter must be changed

regularly so that air conditioner performance

is not adversely affected.

●

Never leave the fresh air fan turned off or

Air conditioning

●

The air conditioner operates most effectively

with the windows and the panoramic sliding

sunroof closed. However, if the vehicle has

heated up after standing in the sun for some

time, the air inside can be cooled more quick-

ly by opening the windows and the panoram-

ic sliding sunroof briefly.

The outside temperature is lower than ap-

If the humidity and temperature 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!

SETTINGS

The temperature display can be changed

from Celsius to Fahrenheit on the screen of

the Infotainment system using the Infotain-

heater: Activate/deactivate the au-

tomatic activation of the auxiliary

heater for colder countries (only for

engines with auxiliary heater). With

the option deactivated, depending on

the outside temperature the heating

may need more time than normal to

reach a comfortable temperature.

Note

After starting the engine, any residual hu-

midity in the air conditioner could mist over

the windscreen. Switch on the defrost func-

tion as soon as possible to clear the wind-

Functioning mode of automatic air recircu-

lation (air conditioning menu)

●

If the cooling system is switched off and

air recirculation mode switched on, the

windows can mist over very quickly, con-

siderably limiting visibility.

With the automatic air recirculation mode ac-

tivated, the entry of fresh air into the cabin in-

terior is enabled. If the system detects a high

concentration of hazardous substances in the

ambient air, air recirculation mode is switched

on automatically. When the level of impurities

drops to within a normal range, recirculation

mode is switched off.

●

Switch air recirculation mode off when it

is not required.

CAUTION

Do not smoke when air recirculation is

switched on in vehicles with an air condi-

tioner. The smoke taken in could lie on the

cooling system vaporiser and on the acti-

vated charcoal cartridge of the dust and

pollen filter, leading to a permanently un-

pleasant smell.

The system is unable to detect unpleasant

smells.

The air recirculation will not connect auto-

matically in versions without humidity sensor

and in the following external conditions:

●

The outside temperature is lower than +3°C

Note

(+38°F).

Climatronic: air recirculation mode is acti-

vated to prevent exhaust gas or unpleasant

odours from entering the vehicle interior

when it is in reverse and while the automat-

ic windscreen wiper is working.

●

The cooling system is switched off and the

outside temperature is below +10°C (+50°F).

●

The cooling system is switched off, the out-

side temperature is below +15°C (+59°F) and

the windscreen wipers are switched on.

Activation/deactivation of automatic air recir-

culation is done in the air conditioner menu,

under Configuration.
