Introduction
Viewing Climatronic information
On the screen of Climatronic control unit and on the screen of the factory-
fitted Easy Connect system, the theoretical values of the temperature zones
are shown.
The unit of temperature measurement can be changed in the Easy Connect
system.
Dust and pollen filter
The dust and pollen filter with its activated charcoal cartridge serves as a
barrier against impurities in the air taken into the vehicle 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 pollution, the filter must be changed more frequently than sta-
ted in the Service Schedule.
Additional information and warnings:
● Easy Connect system
● Seat functions
● Windscreen wipers and washers
● Caring for and cleaning the vehicle exterior
WARNING
Reduced visibility through the windows increases the risk of serious acci-
dents.
● 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 out-
side.
● The maximum heat output required to defrost windows as quickly as
possible is only available when the engine has reached its normal run-
ning temperature. Only drive when you have good visibility.
● Always ensure that you use the heating system, fresh air system, air
conditioner and the heated rear window to maintain good visibility to the
outside.
● 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 reduce driver concentration
possibly resulting 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
● 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 specialist knowledge and special
tools. SEAT recommends visiting a SEAT Official Service.
Note
● When the cooling system 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 button 
.
The button lamp should light up.
● The maximum heat output required to defrost 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. Air conditioner controls

Instructions for use of the air conditioner
The interior cooling system only works when the engine is running and fan
is switched on.
The air conditioner operates most effectively with the windows and the pan-
oramic 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 quickly
by opening the windows and the panoramic sliding sunroof briefly.
Setting for conditions of optimal visibility
When the air conditioning is switched on, the temperature and the air hu-
midity in the vehicle interior drop. Hence, when the outside air humidity is
high, the windows do not mist over and comfort for the vehicle occupants is
improved:
With manual air conditioning
● Switch off air recirculation.
● Set the fan to the required setting.
● Turn the temperature control to the centre position.
● Open and direct all the air outlets in the dash panel.
● Turn the air distribution control to the required position.
● Press the button 
to switch on the cooling system. The button will
light up.
With Climatronic
● Press button 
.
● Set the temperature to +22 °C (+72 °F).
● Open and direct all the air outlets in the dash panel.
Climatronic: change the temperature unit on the screen of the radio or on
the factory-fitted navigation system
Changing the temperature display from Celsius to Fahrenheit on radio or on
the factory-fitted navigation system is done using the menu on the instru-
ment panel ⇒ page 73. The cooling system cannot be activated
If the air conditioning system cannot be switched on, this may be caused by
the following:
●
The engine is not running.
● The fan is switched off.
● The air conditioner fuse has blown.
● The outside temperature is lower than approximately +3 °C (+38 °F).
● The air conditioner compressor has been temporarily switched off be-
cause the engine coolant temperature is too high.
● Another fault in the vehicle. Have the air conditioner checked by a speci-
alised workshop.
Special Characteristics
If the humidity and temperature outside the vehicle are high, condensation
can drip off the evaporator in the cooling system and form a pool under-
neath the vehicle. This is normal and does not indicate a leak!
Note
After starting the engine, any residual humidity in the air conditioner could
mist over the windscreen. Switch on the defrost function as soon as possi-
ble to clear the windscreen of condensation. 

WARNING
Failure to heed the warning lamps when they light up and the corre-
sponding messages may cause the vehicle to stall in traffic and cause ac-
cidents and severe injuries.
● Never ignore the warning lamps or messages.
● Stop the vehicle at the next safe opportunity.
● If the vehicle breaks down or has to be parked for repair, always park
it a safe distance away from the road, switch on the hazard warning
lights, switch off the engine and take other relevant safety measures to
warn vehicles approaching from the rear.
CAUTION
Failure to heed the control lamps when they light up and the corresponding
messages may result in damage to the vehicle. Starting the engine with the ignition key
Switch on the ignition with the key in the ignition and start
the engine.

Steering wheel lock
– To lock the steering wheel, remove the key from the ignition and
turn the wheel until it locks. In vehicles with the automatic gear-
box*, the selector lever must be in the position P in order to re-
move the key.
– To unlock the steering wheel, insert the key into the ignition
and simultaneously turn the key (in the direction of the arrow)
and the steering wheel.

–Turn the ignition key to position 1
to switch off the ignition.
Preheating is produced in Diesel vehicles  when the ignition is
switched on.
Starting up the engine
– Manual gearbox: Press the clutch pedal all the way down and
move the gearbox lever into neutral.
– Automatic gearbox : Press the brake pedal and move the selec-
tor lever to position P or N.
– Turn the ignition key to position 3
. The key returns to position
2 automatically. Do not press the accelerator.
Diesel engines can take a few seconds longer than usual to start
on cold days. Therefore the clutch pedal (manual gearbox) or the
brake pedal (automatic gearbox) must remain pressed until the en-
gine starts up. During preheating, the warning lamp  remains lit.
The preheating time depends on the coolant and exterior tempera-
tures. When the engine is at operating temperature or at outside
temperatures above +8 °C (46 °F) the warning lamp  will only
light up for about one second. This means that the engine starts
immediately.
If the engine does not immediately start up, interrupt the starting process
and try again after 30 seconds. To start the engine again, return the key to
position 1
.
Start-Stop System*
If the vehicle is stopped and the Start-Stop system* switches off the engine,
the ignition remains switched on.
