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.

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 ⇒

Climatronic system. 

162Driving the vehicle with a trailer
WARNING
● Exceeding the maximum established load per axle and the maximum
towing bracket load in addition to the maximum permitted load or the
load of the vehicle + trailer assembly can cause accidents and serious in-
juries.
● A sliding load could considerably affect the stability and safety of the
vehicle + trailer assembly, resulting in accidents and serious injuries.

Towing a trailer
Exterior mirrors
Check whether you can see enough of the road behind the trailer with the
standard rear vision mirrors. If this is not the case, you should have addi-
tional exterior mirrors fitted. Observe the relevant statutory requirements of
the country you are in.
Headlights
Before starting a journey, also check the headlight beam settings with the
trailer hitched up. Adjust the headlight range settings if necessary
⇒ page 96, Range control of main lights .
Driving speed
For your own safety do not drive faster than the maximum permitted speed
indicated on the trailer.
At all times, immediately reduce speed if you detect the slightest swaying
movement of the trailer. Never try to “return the trailer to a straight posi-
tion” by accelerating.
Brakes
Brake in due course! If the trailer has an overrun brake, apply the brakes
gently at first and then, firmly. This will prevent the jerking that can be caused by locking of trailer wheels. Change to a lower gear in good time be-
fore descending a slope in order to take advantage of the engine brake.
The trailer is incorporated into the vehicle anti-theft alarm system.
●
When the vehicle has a factory-fitted anti-theft alarm and a towing
bracket
● When the trailer is electrically connected to the vehicle via the towing
bracket socket
● When the vehicle electrical device and the towing bracket are operation-
al
● When the vehicle is locked and the vehicle anti-theft alarm device is ac-
tivated
Once the electrical connection is interrupted with the vehicle trailer locked,
the alarm sounds.
Always switch off the vehicle anti-theft alarm device before connecting or
disconnecting a trailer. The vehicle anti-theft alarm device could cause the
alarm to sound ⇒ page 88, Anti-theft alarm system.
Engine overheating
In the event that the coolant temperature gauge needle moves to the right
section of the scale or to the red area, immediately reduce speed. If the con-
trol lamp  flashes on the general instrument panel, stop the vehicle and
switch off the engine. Wait several minutes and check the coolant level in
the tank ⇒ page 179.
Please observe the following indications ⇒ page 68, Coolant level and tem-
perature .
The coolant temperature can be reduced by switching on the heating. 

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 

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. 
