Roof carrier
Introduction
The vehicle roof has been designed to optimise aerodynamics. This is why it
is not possible to mount cross bars or conventional roof carrier systems in
the roof's rain channels.
Given that the rain channels have been incorporated into the roof for aero-
dynamic reasons, only SEAT-approved cross bars and roof carrier systems
can be used.
Cases in which the cross bars and roof carrier systems should be
dismounted
● When they are no longer needed.
● When the vehicle is to be washed in a car wash.
● When the vehicle height exceeds the maximum height, for example, in a
garage.

● Storing objects ⇒ page 17
● Driving ecologically ⇒ page 231
● Wheels and tyres ⇒ page 265
● Accessories, parts replacement, repairs and modifications ⇒ page 272
WARNING
Transporting heavy or bulky loads on the roof carrier system affects car
handling due to the shift in the centre of gravity and increased air resist-
ance.
● It is important to always use belts or retaining straps that are suita-
ble and in good condition to secure loads.
● A bulky, heavy, long or flat load has a negative effect on aerodynam-
ics and on the vehicle's centre of gravity and driving behaviour.
● Avoid sudden braking and other brusque manoeuvres.
● Adapt your speed and driving style to suit visibility, weather, road
and traffic conditions.
CAUTION
● Remove the cross bars and the roof carrier system before entering a car
wash.
● The height of your vehicle increases with the installation of the cross
bars and roof carrier system and with the load secured on them. To do so,
make sure that vehicle height does not exceed the height limit when going
through underpasses or garage doors.
● The cross bars, roof carrier system and load on them should not inter-
fere with the roof antenna or hamper the panoramic sliding roof and the
⇒  page 106 rear lid.
● On opening the rear lid, make sure that it does not bump into the roof
load.
For the sake of the environment
Fitting the cross bars and roof carrier system increases fuel consumption
due to greater aerodynamic resistance. 

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. 
