140Air conditioning
● 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. 
Air vents

should remain open.
● Turn the corresponding thumbwheel (detail) in the required direction to
open and close the air vents. When the thumbwheel is in the  position, the
corresponding air vent is closed.

Air conditioning
There are other additional, non-adjustable air vents in the dash panel 2
, in
the footwell and in the rear area of the interior.
Note
Never place food, medicines or other heat-sensitive objects close to the air
vents. Food, medicine and other heat or cold sensitive objects may be dam-
aged or made unsuitable for use by the air coming from the air vents. 
Air recirculation
Basic points
Air recirculation:
Manual air recirculation (heating and fresh air system, manual
air conditioning).
Air recirculation mode prevents the ambient air from entering the interior.
When the outside temperature is very high, selecting manual air recircula-
tion mode for a short period refreshes the vehicle interior more quickly.
For safety reasons, air recirculation mode is switched off when the button
 is pressed or the air distributor turned to .
Switching on and switching off manual air recirculation with air conditioner
(manual) or with the heating and fresh air systems 
Activate: press the button  until the warning lamp lights up.
Deactivate: press the button  until all warning lamps switch off.
Switching on and off manual air recirculation with Climatronic 
Activate: press the * button until the warning lamp lights up.
Deactivate: press the * button until all warning lamps switch off. Functioning mode of manual air recirculation (air conditioning menu)
With the automatic air recirculation mode activated, the entry of fresh air in-
to the cabin interior 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.
The system is unable to detect unpleasant smells.
Air recirculation mode is
not automatically switched on in the following ca-
ses of outside temperatures and conditions:
● The cooling system is switched on (the * button lamp is on) and the am-
bient temperature is below +3 ° C (+38 ° F).
● The cooling system and the windscreen wipers are switched off and the
outside temperature is below +10 °C (+50 °F).
● The cooling system is switched on, the outside temperature is below
+15 °C (+59 °F) and the windscreen wipers are switched on.
Activation/deactivation of automatic air recirculation is done in the air con-
ditioner menu, under Configuration.
WARNING
Stuffy or used air will increase fatigue and reduce driver concentration
possibly resulting in a serious accident.
● Never use recirculation mode for long periods as it does not refresh
the air inside the vehicle.
● If the cooling system is switched off and air recirculation mode
switched on, the windows can mist over very quickly, considerably limit-
ing visibility.
● 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
conditioner. The smoke taken in could lie on the cooling system vaporiser
and on the activated charcoal cartridge of the dust and pollen filter, leading
to a permanently unpleasant smell.
Note
Climatronic: Air recirculation mode switches on to prevent exhaust gas from
entering the vehicle interior when it is in reverse and while the automatic
windscreen wash and wipe is working. 

The profiles, normal, sport and eco are fixed. Individual can be configured
according to personal preferences. 
Description
Depending on the equipment fitted in the vehicle, SEAT Drive Mode can op-
erate on the following functions:
Engine
Depending on the profile selected, the engine responds more spontaneous-
ly or more in harmony with the movements of the accelerator. Additionally,
when eco mode is selected, the Start-stop function is automatically activa-
ted.
In vehicles with DQ transmission, the gear change points are modified to
position them in lower engine speed ranges ( eco) or higher (sport). Addi-
tionally, eco mode activates the Inertia function, enabling the consumption
to be further reduced.
In manual vehicles, eco mode causes the gear recommendation indications
that appear on the instrument panel to vary, facilitating more efficient driv-
ing.
Steering
Power steering becomes more robust in sport mode to enable a more sporty
driving style.
Air conditioning
In vehicles with Climatronic, this can operate in eco mode, especially re-
stricting fuel consumption.
Ambient lighting
The ambient lighting guides located in the interior front door panels of the
Leon FR change colour from white to red when sport mode is activated. Setting driving mode
You can select from Normal, Sport, Eco and Individual.
