Climatronic* (automatic air conditioning) General notes
Climatronic automatically maintains a comfortable temperature. To do so, it
automatically regulates the supplied air temperature and the blower and air
distribution levels. The system also allows for the effect of sunlight, so there
is no need for manual adjustment. Automatic operations ⇒ page 133 guar-
antee maximum comfort any time of year.
Climatronic description
Cooling only works if the following conditions are met:
● The engine is running
● The outside temperature is above +2 °C (+36 °F)
● AC
18 ⇒ Fig. 100 ⇒ page 133 on. In order to ensure engines subject to heavy loads are cooled, the air condi-
tioning compressor is switched off in the event of high coolant tempera-
tures.
Recommended setting for all seasons
●
Set the required temperature. We recommend 22 °C (72 °F).
● Press the AUTO
button 12 ⇒ 
Fig. 100 ⇒  page 133.
● Adjust vents 3 ⇒ page 126 and 4 so that the air flow is directed slightly
upwards.

Temperature selection
–When you switch on the ignition, control 1 ⇒ Fig. 100
⇒ page 133 can be used to set the required interior tempera-
ture.
The interior temperature can be set to between +18 °C (+64 °F) and +29 °C
(+84 °F). The temperature is regulated automatically within this range. If a
temperature below +18 °C (+64 °F) is selected, “LO” is displayed on the
screen. If a temperature above +29 °C (+84 °F) is selected, “HI” is displayed
on the screen. At both extremes, Climatronic works at maximum cooling or
heating power, respectively. The temperature is not regulated.
In the event of prolonged, irregular distribution of the air flow from the out-
lets (particularly the footwells) and significant differences in temperature,
e.g. on leaving the vehicle, sensitive people may catch a cold. 
Air recirculation
Air recirculation prevents unpleasant smells, e.g. when passing
through a tunnel or in queuing traffic, from entering the interior.
Switching on air recirculation mode
– Press button 
17 ⇒ Fig. 100 ⇒ page 133 and the
 sym-
bol is displayed on the screen.
Switching off air recirculation mode
– Press button 
17 ⇒ Fig. 100 ⇒ page 133 and the
 sym-
bol disappears from the screen.
WARNING
Never use the air recirculation system for too long, as it prevents fresh air
from entering the vehicle and “used” air can cause tiredness, reduce your
attention span and cause the windows to mist over. This increases the
risk of an accident. Switch off the air recirculation system as soon as the
windows begin to mist over.
Note
If air recirculation mode remains on for 15 minutes, the  symbol will
start to flash on the screen to indicate prolonged air recirculation. If air recir-
culation is not switched off, the symbol will continue to flash for 5 minutes. 
Blower selection
Climatronic automatically regulates the blower speed according to
the interior temperature. It is possible, however, to set the blower
speed to suit requirements.
– Turn rotary control 10
⇒ Fig. 100 ⇒ 
page 133 anti-clockwise
(decrease speed) or clockwise (increase speed).
Climatronic will switch off when the blower switches off.
WARNING
● “Used air” can cause tiredness, reduce attention spans and cause the
windows to mist over. This increases the risk of an accident.
● Do not switch off Climatronic for longer than necessary.
● Switch Climatronic back on as soon as the windows begin to mist
over.

174Checking and refilling levels
WARNING
● Never open the bonnet if you see steam, smoke or coolant escaping
from the engine compartment. Risk of scalding! Wait until no steam or
coolant can be seen before opening the bonnet.
● Switch off the engine and remove the key from the ignition.
● Engage neutral in vehicles with manual gearbox and move the selec-
tor lever to position P in vehicles with automatic gearbox.
● Apply the handbrake firmly.
● Wait for the engine to cool down.
● For safety reasons, the bonnet must always be closed when the vehi-
cle is moving. Therefore, after closing the bonnet always check that it is
properly secured.
● Should you notice that the bonnet is not safely secured when the ve-
hicle is moving, stop the vehicle immediately and close the bonnet prop-
erly. Risk of accident!
● Keep children away from the engine compartment.
● Do not touch hot engine parts. Risk of burns!
● Never spill fluids on hot engine compartments. These fluids can
cause a fire (e.g. antifreeze in coolant).
● Take care not to cause short circuits in the electrical system, especial-
ly when working on the battery.
● Never touch the radiator fan when the engine is hot. The fan may start
running suddenly!
● Do not unscrew the cap on the coolant expansion tank when the en-
gine is hot. The cooling system is under pressure!
● Protect face, hands and arms from any hot steam or hot coolant re-
leased by covering the cap with a large, thick rag when opening the ex-
pansion tank.
● Do not leave any objects, such as cloths and tools, in the engine com-
partment.WARNING (Continued)
● When working underneath the vehicle, secure it so that it cannot roll
away and support it safely on suitable supports. The hydraulic jack is not
sufficient for this purpose. Risk of injuries!
● If any tests have to be performed with the engine running, there is an
extra safety risk from rotating parts, such as the drive belt, alternator
and radiator fan, etc., and from the high-voltage ignition system. You
should also note the following:
–Never touch the electrical wiring of the ignition system.
– Keep away from moving engine parts when wearing jewellery,
loose clothing or long hair. Risk of fatal injuries! All jewellery must be
removed, hair tied back and close-fitting clothing worn.
● Observe the following additional warnings if work on the fuel system
or the electrical system is necessary.
–Always disconnect the battery from the onboard network.
– Do not smoke.
– Never work near naked flames.
– Always keep an approved fire extinguisher immediately available.
CAUTION
● When topping up fluids, make sure the correct fluid is put into the cor-
rect filler opening. Otherwise this can cause serious malfunctions or engine
damage!
● Never open the bonnet using the release catch. Risk of damage.
For the sake of the environment
Due to the environment-friendly disposal of fluids, the equipment necessary
and the knowledge required, fluids must be changed by an authorised SEAT
dealer during the service inspections of the vehicle. 

Checking and refilling levels
Coolant
General notes
The cooling system is factory-filled with an anti-freeze product.
Coolant consists of a mixture of water and 40% anti-freeze additive. This
mixture gives the required anti-freeze protection at temperatures down to
-25 °C (-13 °F) and protects the cooling and heating system against corro-
sion. It also prevents scaling and raises the boiling point of the coolant con-
siderably.
The coolant concentration must not be reduced by adding water, even in
warmer seasons or in warm countries. The concentration of the anti-freeze
additive in the coolant must be at least 40 %.
If greater anti-freeze protection is required in very cold climates, the propor-
tion of the anti-freeze additive can be increased, but only up to 60 % (anti-
freeze protection down to approx. -40 °C (-40 °F)). Any excess in this propor-
tion would reduce the anti-freeze protection and affect the cooling effect.
Vehicles in countries with a cold climate are supplied with coolant protec-
tion down to around -35 °C (-31 °F). The proportion of anti-freeze additive in
these countries should always be at least 50 %.
The type of anti-freeze to be used for topping up is indicated on the coolant
tank cover ⇒ Fig. 119.
Amount of coolant
Petrol enginesTop-up quantity (in litres)1.2 l/55 kW MPI4,21.2 l/63 kW TSI7,01.2 l/77 kW TSI7,01.4 l/90 kW TSI7,0
Diesel enginesTop-up quantity (in litres)1.6 l/77 kW TDI CR6,5
CAUTION
● Anti-freeze that does not correspond to the correct specification may
particularly affect corrosion protection considerably.
● Faults caused by corrosion may lead to coolant leaks. Risk of serious en-
gine faults! 
Checking coolant level

partment: Coolant tank
The coolant expansion tank is located in the engine compartment
of the vehicle.
– Switch the ignition off.
– Open the bonnet ⇒ page 173.
– Read off the coolant level on coolant expansion tank ⇒ 
Fig. 119.
When the engine is cold, the coolant should be between marks 
Safety FirstOperating instructionsPractical TipsTechnical specifications

180Checking and refilling levels
B
(min.) and A (max.). When the engine is hot, it may be
slightly above mark A (max.).
The warning lamp  (red) in the general instrument panel ⇒ page 68, Cool-
ant level and temperature  will appear when the coolant level is too low.
However, we recommend checking the coolant level directly in the tank.
Coolant loss
Any loss of coolant normally indicates a leak. It is not sufficient merely to
top up the coolant. The cooling system should be inspected by an Official
Service without delay.
CAUTION
In the event of a fault that causes the engine to overheat, contact an author-
ised SEAT dealer immediately, as this could damage the engine. 
Topping up coolant
– Switch the ignition off.
– Wait for the engine to cool down.
– Cover the cap on the coolant expansion tank ⇒ Fig. 119 with a
cloth and carefully unscrew the cap.
– Refill the level of coolant.
– Screw the cap on again until it clicks into place.
Do not use a different type of additive if the prescribed anti-freeze additive
is not available, in the event of an emergency. In this case, use only water
and bring the coolant concentration back up to the correct level as soon as
possible at an Official Service. Always top up with unused coolant.
Never fill the coolant tank above mark
A
(max.) ⇒ Fig. 119 Excess coolant
is forced out of the cooling system through the overpressure valve in the fill-
er cap of the expansion tank when the engine heats up.
WARNING
● The anti-freeze additive and, therefore, the entire coolant, are a
health hazard. Avoid touching the coolant. Coolant fumes are also a
health hazard. Store the coolant additive in a safe place out of the reach
of children. Risk of poisoning!
● If splashed into eyes, rinse immediately with clean water and seek
immediate medical advice.
● Seek immediate medical advice if the coolant is accidentally inges-
ted.
CAUTION
If the engine oil cannot be topped up under the given conditions,  do not
drive on. We recommend contacting an authorised SEAT dealer, as this can
damage the engine. 
Radiator fan
The radiator is driven by an electric motor and controlled according to the
temperature of the coolant.
After the engine has been stopped and the ignition switched off, the radia-
tor fan may continue running for around 10 minutes. 
