Heating and cooling the interior
Fig. 129 On the dash panel: Climatic controls
Interior heating
– Turn the temperature selector ⇒ Fig. 129 1
clockwise to select
the required temperature.
– Turn the blower switch to one of the settings 1-4.
– Set the air distribution control to the air flow configuration de-
sired: 
(towards the windscreen),  (towards the chest), (towards the footwell) and  (towards the windscreen and
footwell areas).
Interior cooling
– Switch on the air conditioner using the button ⇒ Fig. 128 AC
.
– Turn the temperature selector anticlockwise until the desired
cooling output is reached.
– Turn the blower switch to one of the settings 1-4. –
Use the air distribution control to guide the flow of air in the re-
quired direction: 
(to the windscreen),  (to the upper
body),  (to the footwell) and  (to the windscreen and to the
footwell).
Heating
Maximum heat output, which is needed to defrost the windows quickly, is
only available when the engine has reached its operating temperature.
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: 

161
Air conditioning
● The engine is not running.
● The blower is switched off.
● 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. 
Air recirculation mode 
Air recirculation mode prevents fumes or unpleasant smells from coming from the outside.
Fig. 130 On the dash panel: Climatic controls
Air recirculation mode ⇒ Fig. 130 
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).

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 Plan.
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.
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. 

WARNING (Continued)
● Adjust the driver seat or steering wheel so that there is a distance of
at least 25 cm between the steering wheel and your chest ⇒ Fig. 136. If
you fail to observe the minimum distance, the airbag will not protect you.
Risk of fatal injury.
● If your physical constitution does not allow you to maintain the mini-
mum distance of 25 cm, contact a Technical Service. The Technical Serv-
ice will help you to decide if special specific modifications are necessary.
● If you adjust the steering wheel so that it points towards your face,
the driver airbag will not protect you properly in the event of an accident.
Make sure that the steering wheel points towards your chest.
● When driving, always hold the steering wheel with both hands on the
outside of the ring at the 9 o'clock and 3 o'clock positions. Never hold
the steering wheel at the 12 o'clock position, or in any other manner
(e.g. in the centre of the steering wheel, or on the inside of the rim). In
such cases, if the airbag is triggered, you may sustain injuries to the
arms, hands and head.
 Safety
Electronic Stability Control (ESC)*
The ESC helps make driving safer in extreme driving condi-
tions.
Fig. 137 Detailed view of
the centre console: ESC
switch.
The Electronic Stability Control (ESC) contains the electronic differential lock
(EDL) and the traction control system (ASR). The ESC works together with
the ABS. Both control lamps will light up if the ESC or ABS systems are faul-
ty.
The ESC system is started automatically when the engine is started.
The ESC system is always active and cannot be switched off. The ESC switch
only switches the ASR off.
The ASR can be deactivated when wheel spin is desirable.
For example: 

171
Driving
● When driving with snow chains.
● When driving in deep snow or on loose surfaces.
● When the vehicle is stuck, to rock it backwards and forwards.
Press the button to switch the ASR back on when you no longer need wheel
spin.
WARNING
● Do not forget that the Electronic stability control (ESC) cannot defy
the laws of physics. This should be kept in mind, particularly on slippery
and wet roads and when towing a trailer.
● Always adapt your driving style to suit the condition of the roads and
the traffic situation. The greater safety provided by the ESC should not
encourage you to run any risks.
● Please refer to the corresponding warning notes on ESC in
⇒ page 194, Intelligent technology.

Starting 2
The engine is started when the key is in this position. Electrical components
with a high power consumption are switched off temporarily.
Every time the vehicle is started again, the ignition key must be turned to
position 0
. The
repetitive start prevention lock of the ignition prevents
possible damage to the starter motor if the engine is already running.
WARNING
● The ignition key must NOT be removed from the lock until the vehicle
comes to a standstill. Otherwise, the steering could be immediately
blocked- Risk of accident!
● Always remove the key from the ignition when leaving the vehicle,
even for a short period. This is especially important if children or disa-
bled people are left alone in the vehicle. They could accidentally start the
engine or work electrical equipment such as the electric windows, conse-
quently resulting in an accident.
● Unsupervised use of the keys could start the engine or any electrical
system, such as the electric window. This could result in serious injury.
CAUTION
The starter motor will only work when the engine is stopped (ignition key
position 2
). 
Electronic immobiliser
The electronic immobiliser prevents unauthorised persons
from driving the vehicle.
Inside the key there is a chip that deactivates the electronic immobiliser au-
tomatically when the key is inserted into the ignition. The electronic immobiliser will be activated again automatically as soon as
you pull the key out of the ignition lock.
The engine can only be started using a genuine SEAT key with its correct
code.
Note
A perfect operation of the vehicle is ensured if genuine SEAT keys are used. 
Starting and stopping the engine Starting petrol engines
The engine can only be started using a genuine SEAT key
with its correct code. – Move the gearbox lever to the neutral position and depress the
clutch pedal thoroughly and hold it in this position for the start-
er to turn the engine on.
– Turn the ignition key to the starting ⇒ page 171 position.
– Let go of the ignition key as soon as the engine starts; the start-
er motor must not run on with the engine.
After starting a very hot engine, you may need to slightly press down the ac-
celerator.
When starting a very cold engine, it may be a little noisy for the first few sec-
onds until oil pressure has built up in the hydraulic valve compensators.
This is quite normal, and no cause for concern. 

173
Driving
If the engine does not start immediately, switch the starter off after 10 sec-
onds and try again after half a minute. If the engine still does not start, the
fuel pump fuse should be checked ⇒ page 269, Fuses.
WARNING
● Never start or run the engine in unventilated or closed rooms. The ex-
haust gases contain carbon monoxide, an odourless and colourless poi-
sonous gas. Risk of fatal accidents. Carbon monoxide can cause loss of
consciousness. It can also result in death.
● Never leave the vehicle unattended if the engine is running.
● Never use “cold start sprays”, they could explode or cause the engine
to run at high revs. Risk of injury.
CAUTION
● When the engine is cold, you should avoid high engine speeds, driving
at full throttle and over-loading the engine. Risk of engine damage.
● The vehicle should not be pushed or towed more than 50 metres to start
the engine. Unburnt fuel could enter the catalytic converter and damage it.
● Before attempting to push-start or tow a vehicle in order to start it, you
should first try to start it using the battery of another vehicle. Note and fol-
low the instructions in ⇒ page 282, Jump-starting.
For the sake of the environment
Do not warm-up the engine by running the engine with the vehicle station-
ary. Start off immediately, driving gently. This helps the engine reach oper-
ating temperature faster and reduces emissions. Starting diesel engines
The engine can only be started using a genuine SEAT key
with its correct code.
– Move the gearbox lever to the neutral position and depress the
clutch pedal thoroughly and hold it in this position for the start-
er to turn the engine on.
– Turn the ignition key to the starting position.
– Turn the ignition key to position ⇒ Fig. 138 1
. The warning
lamp  will light for engine pre-heating.
– When the lamp turns off, turn the ignition key to position 2
to
start the engine. Do not press the accelerator.
– Let go of the ignition key as soon as the engine starts, the start-
er motor must not be allowed to run on with the engine.
When starting a very cold engine, it may be a little noisy for the first few sec-
onds until oil pressure has built up in the hydraulic valve compensators.
This is quite normal, and no cause for concern.
If there are problems starting the engine, see the ⇒ page 282.
Glow plug system for the diesel engine
To avoid unnecessary discharging of the battery, do not use any other major
electrical equipment while the glow plugs are pre-heating.
Start the engine as soon as the glow plug warning lamp ⇒ page 83 goes
out.
Starting the diesel engine after the fuel tank has been completely run dry
If the fuel tank has been completely run dry, it may take longer than normal
(up to one minute) to start a diesel engine after refuelling. This is because
the fuel system must eliminate air first. 
