Air conditioning
CAUTION
● If you suspect that the air conditioner system is damaged, switch over to
ECON mode to prevent further damage and have the system checked by a
specialised workshop.
● Repairs to the air conditioner require specialist knowledge and special
tools. For this reason, please contact a specialised workshop if the system
is not working properly.
Note
● Keep the air intake slots in front of the windscreen clear of snow, ice and
leaves to ensure unimpaired heating and cooling and to prevent the win-
dows misting over.
● The air from the outlets flows through the passenger compartment and
out through the slots below the rear window. 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 vehicle has heated up after
standing in the sun for some time, the air inside can be cooled more quickly
by opening the windows briefly. 

Fig. 139 button.
The automatic mode maintains a constant temperature inside the vehicle
and dehumidifies the air. Air temperature, air delivery and air distribution
are regulated automatically to reach the desired interior temperature as
quickly as possible, and then to maintain this temperature. The system au-
tomatically compensates for any variations in the outside temperature and
for the effect of direct sunlight.
The automatic temperature regulation only operates at temperature settings
between +18°C and +29°C. If a temperature below +18°C is selected, LO ap-
pears on the display. If a temperature is selected which is higher than +29°C, the display will show
HI. In the maximum and minimum settings, the
climate control operates continuously with maximum cooling or heating
output and the temperature is not regulated automatically. The temperature
is not regulated.
Note
By keeping the AUTO button on the driver side pressed for several seconds,
the temperature of the passenger side can be set to the temperature of the
driver side or vice versa. The display indicates the new temperature value. 

In this setting, the air in the vehicle is constantly recirculated. We recom-
mend using the air recirculation mode in the following circumstances: ●
When driving through a tunnel or in traffic congestions, to prevent ex-
haust gas entering the interior of the vehicle.
WARNING
Do not drive for too long with the air recirculation mode enabled because,
if the compressor is disconnected, the windscreen may mist up because
no fresh air is entering the interior of the vehicle, with the subsequent
risk of accidents.

ECON Mode (economy) ECON
ECON mode helps save fuel.
– To activate, press the ECON
button ⇒ Fig. 139.
– To deactivate, press the ECON
button again or select the AUTObutton.
Air cooling is disconnected in ECON mode. The heating and the blower are
adjusted automatically. “ECON” stands for “Economy”. Disconnecting air
cooling (compressor) reduces fuel consumption.
Please note that the interior temperature must not be lower than the outside
temperature in ECON mode. The blower does not cool or dehumidify the air
in the interior. The windows could therefore mist up.
In diesel vehicles, the auxiliary heater is switched off in ECON mode to save
fuel. 

Air conditioning
Note
If the diode on the ECON button continues to light up when the ECON mode
has been switched off (i.e. the air conditioner has been switched on) this is
due to a defect in one of the air conditioner components. If a malfunction
should occur, please contact a specialised workshop. 
Air recirculation: automatic activation* 
If the outside air is polluted by diesel and petrol emissions,
an air quality sensor in the vehicle will automatically switch
on the air recirculation.

The automatic air recirculation mode should normally be left switched on at
all times.
The system is ready to operate approx. 30 seconds after the engine ignition
key has been turned. During this initial period, fresh air is fed into the vehi-
cle.
If the air purity sensor in the air conditioner detects a certain concentration
of fumes in the outside air, the control unit will either pass the incoming air
through the pollution filter or automatically switch on the air recirculation. If
there is a high concentration of pollution in the outside air, the air condi-
tioner automatically switches to air recirculation and the supply of air from
the outside is cut off. As soon as the level of pollution decreases, air is fed
into the vehicle from the outside again.
The automatic air recirculation operates for a maximum period of 12 mi-
nutes. If the windows mist up when the automatic air recirculation is on,
press the 
button immediately.
The automatic air recirculation switches itself off under certain circumstan-
ces (for instance if 
or  is selected). In “ECON” and at temperatures
lower than approx. 8°C below zero, the automatic air recirculation mode is
limited to 12 seconds. 

170Air conditioning
Air directed to windows 
This setting directs all the air to outlets 1 and 2. Unlike in setting , the
volume of air delivery remains the same.
Air to the driver/front passenger 
All the air comes from outlets 3 and 4 in the dash panel and from the rear of
the centre console.
Air to the footwells 
Most of the air emerges from outlets 5 and the outlets under the front seats.
Some of the air will also be issued from outlets 3 and 4.
Note
In all of the above air distribution settings, a small amount of air will still
come from the other outlets. 
Economical use of the air conditioner
Economical use of the air conditioner will help save fuel.
Engine power is reduced and fuel consumption increases when the
air conditioner is in cooling mode. To ensure that the system is on-
ly switched on when it is really necessary, please note the follow-
ing points:
– Select ECON mode if you wish to save fuel.
– Select ECON mode if you decide to open the windows or sun-
roof* while driving.
– If the vehicle has heated up after standing in the sun, open the
windows and doors for a short time to cool the vehicle.
For the sake of the environment
By saving fuel you also reduce the amount of pollutants emitted from your
vehicle. 
Key settings
When the ignition is switched on, the air conditioner set-
tings assigned to the key are selected automatically.
The air conditioner settings selected are automatically stored and assigned
to the key in use. When the vehicle is started, the air conditioner automati-
cally selects the settings assigned to the key. Hence, every driver automati-
cally obtains his/her preferred settings without having to select them man-
ually.
Note
Should another driver use the key and enter other settings, the previous
settings will be deleted. 
Solar-powered blower/sunroof*
If the vehicle is parked in sufficiently strong sunlight, the
blower will operate in solar-powered mode when the igni-
tion is switched off.
After the ignition is switched off, the blower is supplied with electrical pow-
er from the sunroof. Please ensure that outlets 3 and 4 are open ⇒ Fig. 141
to ensure the best possible ventilation.
The blower only works when the sunroof is closed or tilted open at the rear. 

174Driving
Position 1
The ignition key is inserted in this position. To
engage the steering wheel
lock, take out the key and turn the wheel until you hear the pin engage. You
should always engage the steering lock when you leave the vehicle. This
will help to deter thefts ⇒ 
.
Switching on the ignition/pre-heating glow plugs 2
If the key is difficult to turn in the lock, move the steering wheel (to take the
load off the steering lock mechanism) until the key turns freely. In the case
of vehicles with a diesel engine, the key is turned to this position to preheat
the glow plugs.
Starting the engine 3
The engine is started in this position. Electrical components with a high
power consumption are switched off temporarily.
After the engine has started, the ignition key returns to position 2
by itself.
The ignition key has to be turned back to position 1
before re-starting the
engine. The starter inhibitor in the ignition lock prevents the starter motor
from engaging when the engine is running, as this could cause damage.
Switching off the ignition 1
Turn the ignition key to this position.
WARNING
● Never remove the ignition key until the vehicle is stationary! Other-
wise the steering lock could engage suddenly, which could cause an acci-
dent.
● Always take the key with you when leaving the vehicle, even if you
only intend to be gone for a short time. This is particularly important if
there are children in the vehicle, as they might otherwise be able to start
the engine or use power-operated equipment (e.g. the electric windows),
which could cause injuries.
Note
● If the battery has been disconnected and then reconnected, it will be
necessary to leave the key in position 2
for about 5 seconds before start-
ing the engine.
● Vehicles with automatic gearbox: After switching off the ignition, you
can only remove the ignition key if the selector lever is in position “P” (park-
ing lock). The selector lever is locked after the ignition key has been re-
moved. 
Starting and stopping the engine Starting the engine
The engine can only be started with an original SEAT key.

204Driving and the environment
Avoid idling
It is worthwhile switching off the engine when waiting in a traffic jam, at lev-
el crossings or at traffic lights with a long red phase. The fuel saved after
only 30 - 40 seconds is greater than the amount of fuel needed to restart
the engine.
The engine takes a long time to warm up when it is idling. Mechanical wear
and pollutant emissions are also especially high during this initial warm-up
phase. It is therefore best to drive off immediately after starting the engine.
Avoid running the engine at high speed.
Periodic maintenance
Periodic maintenance work guarantees that, before beginning a journey,
you will not consume more than the required amount of fuel. A well-serviced
engine gives you the benefit of improved fuel efficiency as well as maxi-
mum reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of polluting gases, the engine and
the exhaust filtration systems should reach the optimum service tempera-
ture.
With the engine cold, fuel consumption is proportionally higher. The engine
does not warm up and fuel consumption does not normalise until having
driven approximately four kilometres. This is why we recommend avoiding
short trips whenever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If
the tyre pressure is just one bar too low, fuel consumption can increase by
as much as 5%. Due to the greater rolling resistance, under-inflation also
increases tyre wear and impairs handling.
The tyre pressures should always be checked when the tyres are cold.Do not use
winter tyres all year round as they increase fuel consumption by
up to 10%.
Avoid unnecessary weight
Every kilo of extra weight will put up the fuel consumption, so it is worth
checking the luggage compartment occasionally to make sure that no un-
necessary loads are being transported.
A roof rack is often left in place for the sake of convenience, even when it is
no longer needed. At a speed of 100-120 km/h your vehicle will use about
12% more fuel as a result of the extra wind resistance caused by the roof
rack even when it is not in use.
Save electricity
The engine activates the alternator, which produces electricity. With the
need for electricity, fuel consumption is also increased. Because of this, al-
ways turn off electrical components when you do not need them. Examples
of components that use a lot of electricity are: the fan at high speeds, the
rear window heating or the seat heaters*.
Note
● If you vehicle has Start-Stop, it is not recommended to disconnect this
function.
● It is recommended to close the windows when driving at more than
60 km/h
● Do not drive with your foot resting on the clutch pedal, as the pressure
can make the plate spin, more fuel will be used and it can burn the clutch
plate lining, causing a serious fault.
● Do not hold the vehicle on a hill with the clutch, use the foot brake or
hand brake, using the latter to start. The fuel consumption will be lower and
you will prevent the clutch plate from being damaged.
● On descents, use the engine brake, changing to the gear that is more
suitable for the slope. The fuel consumption will be lower and the brakes
will not suffer. 

Vehicle maintenance and cleaning
General notes
Regular washing and care help maintain the value of your
vehicle.Vehicle maintenance
Regular care and washing help to maintain the value of the vehicle. This
may also be one of the requirements for acknowledging warranty claims in
the event of bodywork corrosion or paint defects.
The best way to protect your vehicle against the harmful effects of the envi-
ronment is through correct maintenance and frequent washing. The longer
substances such as insect remains, bird droppings, resinous tree sap, road
dirt, industrial deposits, tar, soot or road salt and other aggressive materi-
als remain on the vehicle, the more damage they do to the paintwork. High
temperatures (for instance in strong sunlight) further intensify the corrosive
effect.
After winter, a period when salt is put on the roads, it is important to have
the underside of the vehicle washed thoroughly.
Products for vehicle maintenance
Car care products are available in your Technical Services. Keep the product
instructions until you have used them up.
WARNING
● Car care products can be toxic. Because of this, they must always be
kept closed in their original container. Keep them out of the reach of chil-
dren. Failure to comply could result in poisoning.
● Always read and observe the instructions and warnings on the pack-
age before using vehicle care products. Improper use could cause health
problems or damage the vehicle. The use of certain products may pro-
duce noxious vapours; they should be used in well ventilated areas.
● Never use fuel, turpentine, engine oil, nail varnish remover or other
volatile fluids. These are toxic and highly flammable. Risk of fire and ex-
plosion.
● Before washing your vehicle, or carrying out any maintenance, switch
the engine off, apply the handbrake firmly and remove the key from the
ignition.
CAUTION
Never attempt to remove dirt, mud or dust if the surface of the vehicle is dry.
Never use a dry cloth or sponge for cleaning purposes. This could damage
the paintwork or the windows of your vehicle. Soak dirt, mud or dust with
plenty of water.
For the sake of the environment
● When purchasing products for your vehicle maintenance, select the
ones which are not harmful to the environment.
● The waste from car care products should not be disposed of with ordina-
ry household waste. Observe the disposal information on the package. 
