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.
Additional information and warnings:
● Lights ⇒ page 109
● 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. 

Securing the cross bars and roof carrier system
Fig. 112 Roof side bar:
areas for securing cross
bars.
The cross bars are the basis of a series of special roof carrier systems. For
safety reasons, specific systems must be used to safely transport luggage,
bicycles, skis, surf boards or boats on the roof. You can purchase suitable
accessories at SEAT authorised services.
Securing the cross bars and roof carrier system
Always secure the cross bars and roof carrier system. Always refer to the as-
sembly instructions for the cross bars and roof carrier system in question.
The cross bars are fitted to the roof's side bars. The distance between the
cross bars ⇒ Fig. 112 A
should be between 70 and 80 cm. The distance
from the rear cross bar B to the roof antenna should be at least 20 cm.
Once the cross bars have been properly fitted, the roof carrier system
should be secured to them according to the corresponding instructions.
WARNING
Failure to secure the cross bars and roof carrier system properly may lead
the whole system to become detached from the roof and cause an acci-
dent and injury.
● Always take the manufacturer assembly instructions into account.
● Only use cross bars and a roof carrier system that are in good condi-
tion and properly secured.
● Always fit the cross bars and roof carrier system properly.
● Check the threaded joints and attachments before driving and if nec-
essary tighten them after you have travelled a short distance. On long
journeys, check the threaded joints and attachments whenever you take
a rest.
● Always fit the special roof carrier systems correctly for wheels, skis
and surfboards, etc.
● Do not try to change or repair the cross bars or roof carrier system.
Note
Always read the assembly instructions for the cross bars and roof carrier
system carefully and keep them in the vehicle at all times. 
Loading the roof carrier system
Loads can only be secured safely if the cross bars and the roof carrier sys-
tem have been fitted properly ⇒ .
Maximum authorised roof load
The maximum authorised roof load is 75 kg. This figure is the result of add-
ing the weight of the roof carrier system, the cross bars and the roof load
⇒ 
. 
Safety FirstOperating instructionsPractical TipsTechnical specifications

152Seats and storage
Make sure you know the weight of the roof carrier system, the cross bars
and the roof load; weigh them if necessary. Never exceed the maximum au-
thorised roof load.
However, if you are using cross bars and a roof carrier system with a lower
load rating you will not be able to carry the maximum roof load. In this case,
you can only load the roof carrier to the weight limit listed in the fitting in-
structions.
Distributing a load
Uniformly distribute loads and secure them correctly ⇒ 
.
Check attachments.
Once the cross bars and roof carrier system have been fitted, check bolted
joins and the attachments after you have travelled a short distance and
then regularly.
WARNING
Exceeding the maximum authorised roof load can result in accidents and
considerable vehicle damage.
● Never exceed the indicated roof load, the authorised load on the
axles or the vehicle's authorised maximum load.
● Do not exceed the load capacity of the cross bars and roof carrier sys-
tem, even if the maximum roof load has not been exceeded.
● Always secure heavy items as far forward as possible and distribute
the vehicle load uniformly.
WARNING
If the load is loose and is not properly secured it could fall from the roof
carrier system and cause accidents and injury.
● Always use belts or retaining straps that are suitable and in a good
condition.
● Secure the load properly.

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. 

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: 
