ally changes to the previous posi-
tion.
During automatic
wipe
The air conditioner comes on for
approximately 30 seconds in air
recirculation mode to prevent the
smell of the windscreen washer
fluid entering the inside the vehi-
cle.
For the interval wipe
Intervals between wipes depend
on the vehicle's speed. The high-
er the vehicle speed the shorter
the intervals. Heated windscreen washer jets
The heating only thaws the frozen jets, it
does not thaw the water in the washer hoses.
The heated windscreen washer jets automati-
cally adjust the heat depending on the ambi-
ent temperature, when the ignition is switch-
ed on.
Headlight wash/wipe system
The headlight washers/wipers clean the
headlight lenses.
After the ignition is switched on, the first and
every fifth time the windscreen washer is
switched on, the headlights are also washed. Therefore, the windscreen wiper lever should
be pulled towards the steering wheel when
the dipped beam or main beam are on. Any
incrusted dirt (such as insects) should be
cleaned regularly (e.g. when refuelling).
To ensure the headlight washers work cor-
rectly in winter, any snow which has got into
the bumper jet supports should be cleaned
away. If necessary, remove snow with an anti-
icing spray.
Note
The wiper will try to wipe away any obstacles
that are on the windscreen. The wiper will
stop moving if the obstacle blocks its path.
Remove the obstacle and switch the wiper
back on again. Rain sensor*

Operation
●
Always secure objects, even when the lug-
gage compartment floor is properly lifted.
● Only objects that do not protrude more
than 2/3 the height of the floor may be car-
ried between the rear seat and the raised lug-
gage compartment floor.
● Only objects that do not weigh than ap-
proximately 7.5 kg may be carried between
the rear seat and the raised luggage compart-
ment floor. CAUTION
● The maximum weight that can be loaded on
the luggage compartment variable floor in
the top position is 150 kg.
● Do not let the luggage compartment floor
fall when closing it. Always carefully guide it
downwards in a controlled manner. Other-
wise, the lining and the floor of the luggage
compartment could be damaged. Note
SEAT recommends the use of straps to secure
objects to retaining rings. Roof carrier
Introduction The vehicle roof has been designed to opti-
mise aerodynamics. For this reason, cross bars or conventional roof carrier systems can-
not be secured to the roof water drains.
As the roof water drains are integrated in the
roof to reduce air resistance, only SEAT-ap-
proved cross bars and roof carrier systems
can be used.
Cases in which cross bars and the roof
carrier system should be disassembled.
● When they are not used.
● When the vehicle is washed in a car wash.
● When the vehicle height exceeds the maxi-
mum height, for example, in some garages. WARNING
When heavy or bulky loads are transported
on the roof carrier system, car driving per-
formance is affected, as the centre of gravity
shifts and there is greater wind resistance.
● Always secure the load properly using belts
or retaining straps that are suitable and in a
good condition.
● Bulky, heavy, long or flat loads have a neg-
ative effect on aerodynamics, the centre of
gravity and driving performance.
● Avoid sudden braking and manoeuvres.
● Adapt your speed and driving style at all
times to suit visibility, weather, road and traf-
fic conditions. CAUTION
● Remove the cross bars and the roof carrier
system before entering a car wash.
● Vehicle height is increased by the installa-
tion of cross bars or a roof carrier system and
the load secured on them. For this purpose,
check that your vehicle's height does not sur-
pass the headspace limit, for example, for un-
derpasses or for entering garage doors.
● Cross bars, a roof carrier system and the
load secured on them should not interfere
with the roof aerial or hamper the path of the
panoramic sun roof ››› page 92 and the rear
lid.
● On opening the rear lid make sure that it
does not knock into the roof load. For the sake of the environment
When cross bars and a roof carrier system are
installed, the increased air resistance means
that the vehicle uses more fuel. 122

Incorrect attachment and use of the cross-
bars and the roof carrier system may cause
the whole system to detach from the roof and
cause an accident and injuries.
● Always take the manufacturer assembly in-
structions into account.
● Use only crossbars and the roof carrier sys-
tem when they are in perfect condition and
are properly secured.
● Always secure the crossbars and the roof
carrier system properly.
● Check threaded joints and attachments
travelling and if necessary tighten them after
you have travelled a short distance. When
making long trips, check the threaded joints
whenever you stop for a rest.
● Always fit the special roof carrier systems
correctly for wheels, skis and surfboards, etc.
● Do not modify or repair the crossbars or
roof carrier system. » 123

Operation
Note
Always read the assembly instructions that
come with the crossbars and the roof carrier
system carefully and keep them in the vehi-
cle. Loading the roof carrier system
The load can only be secured if the crossbars
and the roof carrier system are properly in-
stalled
››› .
Maximum authorised roof load
The maximum permissible roof load is 75 kg.
This figure comes from the combined weight
of the roof carrier, the cross bars and the load
itself on the roof ››› .
Always check the weight of the roof carrier
system, the cross bars and the weight of the
load to be transported and weigh them if
necessary. Never exceed the maximum au-
thorised roof load.
If you are using cross bars and a roof carrier
with a lower weight rating, you will not be
able to carry the maximum authorised roof
load. In this case, do not exceed the maxi-
mum weight limit for the roof carrier which is
listed in the fitting instructions. Distributing a load
Distribute loads uniformly and secure them
correctly
››› .
Check attachments
Once the cross bars and roof carrier system
have been installed, check the bolted con-
nections and attachments after a short jour-
ney and subsequently with a certain frequen-
cy. WARNING
Exceeding the maximum authorised roof load
can result in accidents and considerable vehi-
cle damage.
● Never exceed the maximum authorised
load on the roof and on the axles or the vehi-
cle's maximum authorised weight.
● Never exceed the load capacity of the cross
bars and the roof carrier system, even if the
maximum authorised roof load has not been
reached.
● Secure heavy items as far forward as possi-
ble and distribute the vehicle load uniformly. WARNING
If the load is loose or not secured, it could fall
from the roof carrier system or cause acci-
dents and injuries.
● Always use belts or retaining straps that
are suitable and in a good condition.
● Secure the load properly. Air conditioning

Viewing Climatronic information
On the screen of Climatronic control unit and
on the screen of the factory-fitted Easy Con-
nect 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 in-
terior.
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 stated in the Service Sched-
ule.

Air conditioning
WARNING
Reduced visibility through the windows in-
creases the risk of serious accidents.
● 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
outside.
● 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. 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 visi-
bility 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 re-
duce 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 spe-
cialist knowledge and special tools. SEAT rec-
ommends 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 recom-
mends leaving the cooling system (compres-
sor) turned on. To do this, press the button  . The button lamp should light up.
● 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.
● Keep the air intake slots in front of the
windscreen free of snow, ice and leaves to en-
sure heating and cooling are not impaired,
and to prevent the windows from misting
over. Adjust using the Easy Connect

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 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.

fitted navigation system
Changing the temperature display from Cel-
sius to Fahrenheit on radio or on the factory-
fitted navigation system is done using the
menu on the instrument panel
›››
page 72.
The cooling system cannot be activated
If the air conditioning system cannot be
switched on, this may be caused by the fol-
lowing:
● The engine is not running.
● The fan is switched off.
● The air conditioner fuse has blown.
● The outside temperature is lower than ap-
proximately +3°C (+38°F).
126

Air conditioning
● The air conditioner compressor has been
temporarily switched off because the engine
coolant temperature is too high.
● Another fault in the vehicle. Have the air
conditioner checked by a specialised work-
shop. Special Characteristics
If the humidity and temperature outside the
vehicle are high,
condensation
can drip off
the ev
aporator in the cooling system and
form a pool underneath the vehicle. This is
normal and does not indicate a leak! Note
After starting the engine, any residual humid-
ity in the air conditioner could mist over the
windscreen. Switch on the defrost function as
soon as possible to clear the windscreen of
condensation. Air vents

s closed.
● Change the air direction using the ventila-
tion grille lever.
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
Food, medicine and other heat or cold sensi-
tive objects should never be placed in front of
the air outlets as they may be damaged or
made unsuitable for use by the air coming
from the air vents. 127


Manual recirculation
Air recirculation mode prevents the ambient
air from entering the interior.
When the outside temperature is very high,
selecting manual air recirculation mode for a
short period refreshes the vehicle interior
more quickly.
For safety reasons, air recirculation mode is
switched off when the button
 is press-
ed or the air distributor turned to .
Switching the manual air recirculation mode
on and off 
To switch system on: press the  button un-
til the warning lamp lights up.
To switch system off: press the  button un-
til the warning lamp goes off.
Functioning mode of automatic air
recirculation (air conditioning menu)
With the automatic air recirculation mode ac-
tivated, the entry of fresh air into 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, re-
circulation mode is switched off.
The system is unable to detect unpleasant
smells.
The air recirculation will
not connect auto-
m atic
ally in versions without humidity sensor
and in the following external conditions:
● The outside temperature is lower than +3°C
(+38°F).
● 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. WARNING
Observe the safety warnings ››› in Intro-
duction on page 125.
● If the c

ooling 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 condition-
er. The smoke taken in could lie on the cool-
ing system vaporiser and on the activated
charcoal cartridge of the dust and pollen fil-
ter, leading to a permanently unpleasant
smell. Note
Climatronic: air recirculation mode is activa-
ted to prevent exhaust gas or unpleasant
odours from entering the vehicle interior
when it is in reverse and while the automatic
windscreen wiper is working. 128
