Air conditioning
Instructions for use of the air conditioner
The interior cooling system only works when the engine is running and fan
is switched on.
The air conditioner operates most effectively with the windows and the pan-
oramic sliding 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 and the panoramic sliding sunroof briefly.
Setting for conditions of optimal visibility
When the air conditioning is switched on, the temperature and the air hu-
midity in the vehicle interior drop. Hence, when the outside air humidity is
high, the windows do not mist over and comfort for the vehicle occupants is
improved:
With manual air conditioning
● Switch off air recirculation.
● Set the fan to the required setting.
● Turn the temperature control to the centre position.
● Open and direct all the air outlets in the dash panel.
● Turn the air distribution control to the required position.
● Press the button 
to switch on the cooling system. The button will
light up.
With Climatronic
● Press button 
.
● Set the temperature to +22 °C (+72 °F).
● Open and direct all the air outlets in the dash panel.
Climatronic: change the temperature unit on the screen of the radio or on
the factory-fitted navigation system
Changing the temperature display from Celsius to Fahrenheit on radio or on
the factory-fitted navigation system is done using the menu on the instru-
ment panel ⇒ page 73. The cooling system cannot be activated
If the air conditioning system cannot be switched on, this may be caused by
the following:
●
The engine is not running.
● The fan is switched off.
● The air conditioner fuse has blown.
● The outside temperature is lower than approximately +3 °C (+38 °F).
● The air conditioner compressor has been temporarily switched off be-
cause the engine coolant temperature is too high.
● Another fault in the vehicle. Have the air conditioner checked by a speci-
alised workshop.
Special Characteristics
If the humidity and temperature outside the vehicle are high, condensation
can drip off the evaporator in the cooling system and form a pool under-
neath the vehicle. This is normal and does not indicate a leak!
Note
After starting the engine, any residual humidity in the air conditioner could
mist over the windscreen. Switch on the defrost function as soon as possi-
ble to clear the windscreen of condensation. 

Air vents
Fig. 116 On the dash panel: air vents
Air vents
To ensure proper heating, cooling and ventilation in the vehicle interior, air
vents ⇒ Fig. 116 1
should remain open.
● Turn the corresponding thumbwheel (detail) in the required direction to
open and close the air vents. When the thumbwheel is in the  position, the
corresponding air vent is closed.
● Change the air direction using the ventilation grille lever.
There are other additional, non-adjustable air vents in the dash panel 2
, in
the footwell and in the rear area of the interior.
Note
Never place food, medicines or other heat-sensitive objects close to the air
vents. Food, medicine and other heat or cold sensitive objects may be dam-
aged or made unsuitable for use by the air coming from the air vents. Air recirculation
Basic points
Air recirculation:
Manual air recirculation (heating and fresh air system, manual
air conditioning).
Air recirculation mode prevents the ambient air from entering the interior.
When the outside temperature is very high, selecting manual air recircula-
tion mode for a short period refreshes the vehicle interior more quickly.
For safety reasons, air recirculation mode is switched off when the button
 is pressed or the air distributor turned to
.
Switching on and switching off manual air recirculation with air conditioner
(manual) or with the heating and fresh air systems 
Activate: press the button  until the warning lamp lights up.
Deactivate: press the button  until all warning lamps switch off.
Switching on and off manual air recirculation with Climatronic 
Activate: press the * button until the warning lamp lights up.
Deactivate: press the * button until all warning lamps switch off.
Functioning mode of manual air recirculation (air conditioning menu)
With the automatic air recirculation mode activated, the entry of fresh air in-
to the cabin interior is enabled. If the system detects a high concentration
of hazardous substances in the ambient air, air recirculation mode is
switched on automatically. When the level of impurities drops to within a
normal range, recirculation mode is switched off.
The system is unable to detect unpleasant smells.
Air recirculation mode is not automatically switched on in the following ca-
ses of outside temperatures and conditions: 

161
Air conditioning
● The cooling system is switched on (the * button lamp is on) and the am-
bient temperature is below +3 °C (+38 °F).
● The cooling system and the windscreen wipers are switched off and the
outside temperature is below +10 °C (+50 °F).
● The cooling system is switched on, the outside temperature is below
+15 °C (+59 °F) and the windscreen wipers are switched on.
Activation/deactivation of automatic air recirculation is done in the air con-
ditioner menu, under Configuration.
WARNING
Stuffy or used air will increase fatigue and reduce driver concentration
possibly resulting in a serious accident.
● Never use recirculation mode for long periods as it does not refresh
the air inside the vehicle.
● If the cooling system is switched off and air recirculation mode
switched on, the windows can mist over very quickly, considerably limit-
ing visibility.
● Switch air recirculation mode off when it is not required.
CAUTION
Do not smoke when air recirculation is switched on in vehicles with an air
conditioner. The smoke taken in could lie on the cooling system vaporiser
and on the activated charcoal cartridge of the dust and pollen filter, leading
to a permanently unpleasant smell.
Note
Climatronic: Air recirculation mode switches on to prevent exhaust gas from
entering the vehicle interior when it is in reverse and while the automatic
windscreen wash and wipe is working. 

Failure to heed the warning lamps when they light up and the corre-
sponding messages may cause the vehicle to stall in traffic and cause ac-
cidents and severe injuries.
● Never ignore the warning lamps or messages.
● Stop the vehicle at the next safe opportunity.
● If the vehicle breaks down or has to be parked for repair, always park
it a safe distance away from the road, switch on the hazard warning
lights, switch off the engine and take other relevant safety measures to
warn vehicles approaching from the rear.
CAUTION
Failure to heed the control lamps when they light up and the corresponding
messages may result in damage to the vehicle. Starting the engine with the ignition key

Steering wheel lock
– To lock the steering wheel, remove the key from the ignition and
turn the wheel until it locks. In vehicles with the automatic gear-
box*, the selector lever must be in the position P in order to re-
move the key.
– To unlock the steering wheel, insert the key into the ignition
and simultaneously turn the key (in the direction of the arrow)
and the steering wheel.
Warning: If the steering wheel cannot be turned, this is because
the steering wheel lock is activated.

–Turn the ignition key to position 1
to switch off the ignition.
Preheating is produced in Diesel vehicles  when the ignition is
switched on.
Starting up the engine
– Manual gearbox: Press the clutch pedal all the way down and
move the gearbox lever into neutral.
– Automatic gearbox : Press the brake pedal and move the selec-
tor lever to position P or N.
– Turn the ignition key to position 3
. The key returns to position
2 automatically. Do not press the accelerator.
Diesel engines can take a few seconds longer than usual to start
on cold days. Therefore the clutch pedal (manual gearbox) or the
brake pedal (automatic gearbox) must remain pressed until the en-
gine starts up. During preheating, the warning lamp  remains lit.
The preheating time depends on the coolant and exterior tempera-
tures. When the engine is at operating temperature or at outside
temperatures above +8 °C (46 °F) the warning lamp  will only
light up for about one second. This means that the engine starts
immediately.
If the engine does not immediately start up, interrupt the starting process
and try again after 30 seconds. To start the engine again, return the key to
position 1
.
Start-Stop System*
If the vehicle is stopped and the Start-Stop system* switches off the engine,
the ignition remains switched on.
Automatic gearbox: Before leaving the vehicle, make sure that the ignition
is switched off and the selector lever is in position P. Driver messages on the instrument panel display
Press the clutch This message appears on vehicles with a manual gearbox if the driver tries
to start the engine without having the clutch pedal pressed. The engine will
only start if you press the clutch pedal.
Press the brake
This message appears on vehicles with an automatic gearbox if the driver
tries to start the engine without having the brake pedal pressed.
Select N or P
This message appears if you try to start or stop the engine when the selec-
tor lever of the automatic gearbox is not in position P or N. The engine can
only start or stop in these positions.
Engage position P; the vehicle can move; doors can only close in position P. For safety reasons, this driver message appears and an audible warning
sounds if the selector lever of the automatic gearbox is not in position P af-
ter you switch off the ignition. Otherwise the vehicle could move.
Gear change: selector lever in the drive position!
This driver message is displayed and a buzzer is sounded when the selector
lever is not in the position P when the driver door is opened. Put the selec-
tor lever in position P; otherwise the vehicle can roll away.
Ignition is switched onThis driver message is displayed and a buzzer is sounded when the driver
door is opened with the ignition switched on. 

Driving
WARNING
● Never run the engine in confined spaces, as the exhaust gases are
poisonous.
● Never remove the key from the ignition if the vehicle is in motion.
Otherwise, the steering could suddenly lock, making it impossible to
steer the vehicle: risk of accident!
● Always take the key with you when you leave the vehicle. This is par-
ticularly important if there are children in the vehicle, as they might oth-
erwise be able to start the engine or use power-operated equipment (e.g.
the electric windows), which could cause injuries.
CAUTION
Avoid high engine speeds, full throttle and extreme load conditions until
the engine has reached its normal operating temperature, otherwise this
can damage the engine.
For the sake of the environment
Do not warm up the engine by running it with the car stationary. You should
drive off as soon as you start the engine. This will help avoid unnecessary
exhaust emissions.
Note
● If it is difficult to turn the ignition key to the position 1, turn the steer-
ing wheel to both sides to release the steering lock.
● When starting from cold, the engine may be a little noisy for the first few
seconds until oil pressure has built up in the hydraulic valve lifters. This is
quite normal, and no cause for concern.
● If the vehicle battery is disconnected and reconnected, the key must re-
main in the position 1
for around 5 seconds before starting up.
● 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). Next, the selector lever is locked. Switching off the engine with the key
Switching off the engine
–
Stop the vehicle.
– Turn the ignition key to position 1
⇒ Fig. 118.
Engaging the steering wheel lock
Important: selector lever (automatic gearbox*) must be in position
P.
– Remove the key from the ignition in position 1
⇒ Fig. 118
⇒ .
– Turn the steering wheel until you hear it engage.
Possible vehicle theft is prevented with the steering lock engaged.
WARNING
● Never switch the engine off until the vehicle is stationary. The brake
servo and power steering functions will not be completely covered under
warranty. More force may also be needed to turn the steering wheel or to
brake. As you cannot steer and brake in the normal manner, there is a
greater risk of accidents and serious injury.
● Never remove the key from the ignition if the vehicle is in motion.
Otherwise, the steering could lock making it impossible to steer the vehi-
cle.
● Always take the ignition key with you whenever you leave the vehicle,
even temporarily. 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. 

CAUTION
If the engine has been running under high load for a long time, there is a
risk of heat building up in the engine compartment after the engine has
been switched off; this could cause engine damage. For this reason, you
should idle the engine for approx. 2 minutes before you switch it off.
Note
● After the engine is switched off the radiator fan may run on for up to 10
minutes, even if the ignition is switched off. It is also possible that the fan
turns itself on once more if the coolant temperature increases due to the
heat accumulated in the engine compartment or due to its prolonged expo-
sure to solar radiation.
● If the vehicle is stopped and the Start-Stop system* switches off the en-
gine, the ignition remains switched on. Make sure that the ignition is
switched off before leaving the vehicle, otherwise the battery could dis-
charge. 
Kick-down
The kick-down feature allows maximum acceleration to be
reached. If the eco*
⇒ page 212 mode has been selected in SEAT Drive Mode*, and
the accelerator is pressed beyond a hard point, the engine power is auto-
matically controlled to give your vehicle maximum acceleration.
WARNING
Please note that if the road surface is slippery or wet, the kick-down fea-
ture could cause the driving wheels to spin, which could result in skid-
ding.
 Handbrake
Using the handbrake
The handbrake should be applied firmly to prevent the vehi-
cle from accidentally rolling away.
