footwell). 

162Air conditioning
Air recirculation mode ⇒ fig. 131 
prevents strong odours in the outside
air from entering the vehicle interior, for example when passing through a
tunnel or in queuing traffic.
With low temperatures outside, the air recirculation increases the effective-
ness of the heating system by warming the air inside the vehicle rather than
the cold air from outside.
With high outside temperatures, the air recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the vehicle
rather than the ambient air.
If the windscreen air output is on and the air recirculation mode is pressed,
this remains active. When the recirculation mode is on, if the air distribution towards the windscreen mode is selected, the recirculation mode is deacti-
vated. For safety reasons, the air recirculation mode should not be connec-
ted.
WARNING
In air recirculation mode, no cold air from the outside enters the vehicle
interior. If the air conditioning system is switched off, the windows can
quickly mist over. Therefore, never leave the air recirculation mode
switched on for a long time (risk of accident).

166Air conditioning
Manual mode
In manual mode you can adjust the air temperature, air flow and distribution as required.
Fig. 135 On the dash panel: 2C Climatronic controls.
Switching on manual mode
– To enter manual mode, press one of the buttons ⇒ fig. 135 1
to 5 or press the air flow control 10. The selected function is
shown on the radio or navigator display.
Temperature
There are separate temperature selectors for the left and right sides of the
vehicle interior. The selected temperature is displayed above the selector.
The inside temperature can be set between +18 °C (64 °F) and +26 °C
(80 °F). These are approximate temperatures and the actual temperature
may be slightly higher or lower depending on the ambient conditions.
If a temperature below 18 °C (64 °F) is selected, the display switches to LO
In this setting the system runs at maximum cooling output and the tempera-
ture is not regulated. If a temperature above 26 °C (80 °F) is selected, the display switches to
HI
In this setting the system runs at maximum heating output and the temper-
ature is not regulated.
Blower
The air flow may be adjusted freely using the control 10
. Always have the
blower running at a low setting to ensure a constant flow of fresh air into
the vehicle. Pushing the button  to the minimum -1, turns the Climatronic
off.
Air distribution
The air distribution is adjusted using the buttons 
,  and . It is also
possible to open and close some of the air vents separately.
Switching the air conditioning on and off
When the AC
button is on (LED lit), the air conditioning system is on.


Air conditioning
When the AC
button is off (LED off), the air conditioning system is off.
When the AC
button is off, the air conditioning system is switched off to
save fuel. The temperature continues to self-regulate. The set temperature
can then only be reached if it is higher than the outside temperature.
Driver and passenger temperature control
The DUAL
button controls the synchronisation of the 2 Climatronic climate
zones.
When the DUAL
button is on (LED lit), the climate zone of the Climatronic is
personalised, for example: Driver side temperature 22 °C and passenger
side temperature 23 °C.
When the DUAL
button is off (LED off), the climate zone of the Climatronic is
synchronised, for example: Driver side temperature 22 °C and passenger
side temperature 22 °C.
If the DUAL
button is off and the passenger side temperature is changed,
the function is automatically activated. 
Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells
from coming from the outside. – Press the button 
⇒ fig. 135
2 to switch air recirculation
mode on or off. It is switched on if the following symbol appears
in the display .
Air recirculation mode prevents strong odours in the ambient air from enter-
ing the vehicle interior, for example when passing through a tunnel or in a
traffic jam. With low outside temperatures, the air recirculation increases the effective-
ness of the heating system by heating the air inside the vehicle rather than
the air from outside.
With high outside temperatures, the air recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the vehicle
rather than the ambient air.
If the windscreen air output is on and the air recirculation mode is pressed,
this remains active. When the recirculation mode is on, if the air distribution
towards the windscreen mode is selected, the recirculation mode is deacti-
vated. For safety reasons, the air recirculation mode should not be connec-
ted.
WARNING
In air recirculation mode, no cold air from the outside enters the vehicle
interior. If the air conditioning system is switched off, the windows can
quickly mist over. Therefore, never leave the air recirculation mode
switched on for a long time (risk of accident).

General notes
Pollution filter
The pollution filter (a combined particulate filter and active carbon filter)
serves as a barrier against impurities in the outside air, including dust and
pollen.
For the air conditioner to work with maximum efficiency, the pollution filter
must be replaced at the intervals specified in the Service Schedule.
If the filter loses efficiency prematurely due to use in areas reaching very
high pollution levels, the pollen filter must be changed more frequently
than stated in the Service Schedule. 

168Air conditioning
Air conditioner
When the air conditioning system is switched on, not only the temperature,
but also the air humidity in the vehicle interior is reduced. This improves
comfort for the vehicle occupants and prevents misting of the windows
when the ambient air humidity is high.
If the air conditioning system cannot be switched on this may be caused by
the following reasons:
● The engine is not running.
● The AC
button is disconnected.
● The outside temperature is below +3 °C.
● The air conditioning system compressor has been temporarily switched
off because the engine coolant temperature is too high.
● The air conditioner fuse is faulty.
● Another fault in the vehicle. Have the air conditioner checked by a speci-
alised workshop.
CAUTION
● If you suspect that the air conditioner is damaged, switch it off with but-
ton AC
to prevent further damage and have it checked by a specialised
workshop.
● Repairs to the air conditioner require specialist knowledge and special
tools. Therefore, we recommend you to take the vehicle to a specialised
workshop.
Note
● If the humidity and temperature outside the vehicle are high, condensa-
tion can drip off the evaporator in the cooling system and so forming a pud-
dle underneath the vehicle. This is completely normal and there is no need
to suspect a leak.
● 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. ●
The air from the vents flows through the vehicle interior and is extracted
by slots designed for this purpose. Therefore, do not cover these slots with
items of clothing or other objects.
● The air conditioner operates most effectively with the windows and the
sliding/tilting sunroof* closed. However, if the temperature inside the vehi-
cle is excessive because of the sun, the air inside can be cooled faster by
opening the windows for a short time.
● Do not smoke while air recirculation mode is on, as smoke drawn into
the air conditioning system leaves a residue on the evaporator, producing a
permanent unpleasant odour.
● It is advisable to connect the air conditioning at least once a month, to
lubricate the system gaskets and prevent leaks. If a decrease in the cooling
capacity is detected, an Authorised Service Centre should be consulted to
check the system. 

210Trailer towing
Fig. 159 Attachment
points for towing bracket If a towing bracket is to be fitted after the vehicle is purchased, this must be
completed according to the instructions of the towing bracket manufacturer.
The attachment points for the towing bracket
A
are on the lower part of the
vehicle.
The distance between the centre of the ball coupling and the ground should
never be lower than the indicated value, even with a fully loaded vehicle
and including the maximum drawbar load.
Elevation values for securing the towing bracket:
65 mm (minimum)
350 mm to 420 mm (fully laden vehicle)
344 mm
531 mm
1044 mm
1040 mm
Fitting a towing bracket
● Driving with a trailer involves an extra effort for the vehicle. Therefore,
before fitting a towing bracket, please contact an Authorised Service Centre
to check whether your cooling system needs modification.
● The legal requirements in your country must be observed (e.g. the fitting
of a separate warning lamp).
● Certain vehicle components, e.g. the rear bumper, must be removed and
reinstalled. The towing bracket securing bolts must be tightened using a
torque wrench, and a power socket must be connected to the vehicle's elec-
trical system. This requires specialised knowledge and tools.
● Figures in the illustration show the elevation value and the attachment
points which must be considered if you are retrofitting a towing bracket. 

Checking and refilling levels
You should not do any work in the engine compartment unless you know ex-
actly how to carry out the jobs and have the correct tools! Have the work car-
ried out by a specialised workshop if you are uncertain.
All service fluids and consumables, e.g. coolant, engine oil, spark plugs
and batteries, are under constant development. SEAT provides a constant
flow of information to the Authorised Service Centres concerning modifica-
tions. For this reason, we recommend you to have service fluids and con-
sumables replaced by an Authorised Service Centre. Please observe the rel-
evant instructions ⇒ page 221. The engine compartment of the vehicle is a
hazardous area ⇒ 
.
WARNING
All work on the engine or in the engine compartment, e.g. checking and
refilling fluids, involves the danger of injury and scalding as well as the
risk of accident or fire.
● Never open the bonnet if you see steam, smoke or coolant escaping
from the engine compartment. Otherwise, there is a risk of sustaining
burns. Wait until no more steam or coolant is emitted, then allow the en-
gine to cool before carefully opening the bonnet.
● Switch off the engine and remove the key from the ignition.
● Apply the handbrake and move the gear lever to neutral or selector
lever to position P.
● Keep children away from the vehicle.
● Never touch hot engine parts. There is a risk of burns.
● Never spill liquids on a hot engine or on a hot exhaust gas system.
This is a fire hazard.
● Avoid causing short-circuits in the electrical system, particularly at
the points where the jump leads are attached ⇒ page 280. The battery
could explode.
WARNING (Continued)
● Never touch the radiator fan. It is temperature controlled and could
start automatically, even when the engine has been switched off and the
key removed from the ignition!
● Do not unscrew the cap on the expansion tank when the engine is
hot. If the coolant is hot, the cooling system will be pressurised!
● Protect face, hands and arms by covering the cap with a large, thick
cloth to protect against escaping coolant and steam.
● Always make sure you have not left any objects, such as cleaning
cloths and tools, in the engine compartment.
● If you have to work underneath the vehicle, you must use suitable
stands additionally to support the vehicle, there is a risk of accident!. A
hydraulic jack is insufficient for securing the vehicle and there is a risk of
injury.
● If any work has to be performed when the engine is started or with
the engine running, there is an additional, potentially fatal, safety risk
from the rotating parts, such as the drive belts, alternator, radiator fan,
etc., and from the high-voltage ignition system. You should also observe
the following points:
–Never touch the electrical wiring of the ignition system.
– Ensure that jewellery, loose clothing and long hair do not get trap-
ped in rotating engine parts. Danger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
– Never accelerate with a gear engaged without taking the necessary
precautions. The vehicle could move, even if the handbrake is ap-
plied. Danger of death.
● If work has to be carried out on the fuel system or on electrical com-
ponents, you must observe the following safety notes in addition to the
above warnings:
–Always disconnect the battery. The vehicle must be unlocked when
this is done, otherwise the alarm will be triggered.
– Do not smoke. 

Checking and refilling levels
WARNING
Only change the oil yourself if you have the specialist knowledge re-
quired!
● Before opening the bonnet, read and observe the warnings
⇒ page 230, Safety instructions on working in the engine compartment.
● Wait for the engine to cool down. Hot oil may cause burn injuries.
● Wear eye protection to avoid injuries caused by splashes of oil.
● When removing the oil drain plug with your fingers, keep your arm
horizontal to help prevent oil from running down your arm.
● Wash your skin thoroughly if it comes into contact with engine oil.
● Engine oil is poisonous! Used oil must be stored in a safe place out of
the reach of children.
CAUTION
No additives should be used with engine oil. This could result in engine
damage. Any damage caused by the use of such additives would not be
covered by the factory warranty.
For the sake of the environment
● Because of the disposal problems, the necessary special tools and spe-
cialist knowledge required, we recommend that you have the engine oil and
filter changed by an Authorised Service Centre.
● Never pour oil down drains or into the ground.
● Use a suitable container when draining the used oil. It must be large
enough to hold all the engine oil. Coolant
Coolant specifications
Coolant is a mixture of water and at least 40% coolant addi-
tive. The cooling system must be filled with a mixture of water and at least 40 %
of our coolant additive G12+ or an additive with the specification TT-VW 774
F (it is dyed purple). This mixture provides the necessary freeze protection
down to -25 °C and protects the alloy parts of the cooling system against
corrosion. It also prevents scaling and raises the boiling point of the cool-
ant.
The concentration of coolant must always be at least 40% - even if freeze
protection is not required.
If greater freeze protection is required in very cold climates, the proportion
of the antifreeze additive G12+ can be increased. However, the percentage
of coolant additives should not exceed 60%, as this would reduce the
freeze protection. It would also reduce the cooling effect. A mixture with
60% additive will give antifreeze protection to approx. -40 °C.
WARNING
● The coolant additive is toxic. There is a toxic risk. Always keep the
coolant additive in the original container which should be stored out of
the reach of children. The same applies to coolant which you have
drained off.
● The coolant additive G12+ must be added in sufficient quantities to
provide anti-freeze protection at the coldest ambient temperatures that
can be expected. At extremely cold outside temperatures, the coolant
could freeze, causing the vehicle to breakdown. As the heater would not
work either, there is a risk of freezing to death. 
Safety FirstOperating InstructionsPractical TipsTechnical Specifications

238Checking and refilling levels
CAUTION
● Other additives may give considerably inferior corrosion protection. The
resulting corrosion in the cooling system can lead to a loss of coolant, caus-
ing serious damage to the engine.
● The coolant additive G12+ (purple) can be mixed with the additive G12
(red) or G11. Never mix G12 (red colour) with G11. 
Checking the coolant level and topping up 
The correct coolant level is important for fault-free function-
ing of the engine cooling system.

compartment: Coolant
expansion tank cap
Before opening the bonnet, read and observe the warnings ⇒ 
in
Safety instructions on working in the engine compartment on
page 230. Opening the coolant expansion tank
–
Switch off the engine and allow it to cool.
– To prevent scalding, cover the cap on the expansion tank with a
thick cloth and carefully unscrew the cap ⇒ 
.
Checking coolant level
– Look into the open coolant expansion tank and read off the
coolant level.
– If the level is below the “MIN” mark, top up with coolant.
Topping up coolant
– Only use new coolant liquid.
– Do not fill above the “MAX” mark.
Closing the coolant expansion tank
– Screw the cap on again tightly.
The position of the coolant expansion reservoir is shown in the correspond-
ing engine compartment illustration ⇒ page 289.
Make sure that the coolant meets the required specifications ⇒ page 237.
Do not use a different type of additive if additive G12+ is not available. In
this case use only water and bring the coolant concentration back up to the
correct level as soon as possible by putting in the specified additive
⇒  page 237.
Always top up with new coolant.
Do not fill above the “MAX” mark. Otherwise the excess coolant will be
forced out of the cooling system when the engine is hot.
The coolant additive G12+ (dyed purple) may be mixed with G12 (dyed red)
and also with G 11. 
