Air conditioning
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: ●
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.

The LEDs on the Climatronic controls indicate that the selected function has
been activated.
In addition, the radio or radio and navigation displays mounted at factory
briefly display the current settings of the Climatronic if any are modified.
The symbols used on the radio or radio and navigation displays are the
same as the symbols used for the Climatronic controls. 
Automatic mode
In automatic mode air temperature, air flow and distribution
are automatically regulated so that a specified temperature
is attained as quickly as possible and then maintained. The temperature can be adjusted separately for the left and right
sides of the vehicle interior.
Switching on automatic mode
– Press the AUTO
⇒ 
fig. 110 button. “AUTO High” is shown on the
radio display (high fan speed).
– Press the AUTO
button again ⇒ fig. 110. “AUTO Low” is shown
on the radio display (low fan speed).
Depending upon the version and finish, the vehicle may include: When a temperature of 22°C (72°F) is set in automatic mode a comfortable
interior climate is quickly reached. Therefore, we recommend you not to
change this adjustment, except as necessary to suit individual preferences
or particular circumstances. The inside temperature can be set between
+18°C (64°F) and +26°C (80°F). These are approximate temperatures and
the actual temperature may be slightly higher or lower depending on the
ambient conditions.
Climatronic maintains a constant temperature. The temperature of the air
supplied to the interior, the blower speed and the air distribution are regu-
lated automatically. The system also considers the sunlight radiation, so
there is no need for manual readjustment. Therefore,
automatic mode al-
most always provides the best comfort for the vehicle occupants throughout
the year.
Automatic mode is switched off whenever an adjustment is made using the
buttons for the air distribution, air flow or 
or the air recirculation button
. The temperature will continue to be regulated within the parameters
manually selected by the user.
Note
There are two automatic modes:
● Automatic mode LO: This calculates the air flow for two people.
● Automatic mode HI: This calculates the air flow for more than two peo-
ple. 

Air conditioning
When the AC
button is off (LED off), the air conditioning system is off.
When the AC
button is off, the air conditioning system is switched off to
save fuel. The temperature continues to self-regulate. The set temperature
can then only be reached if it is higher than the outside temperature.
Driver and passenger temperature control
The DUAL
button controls the synchronisation of the 2 Climatronic climate
zones.
When the DUAL
button is on (LED lit), the climate zone of the Climatronic is
personalised, for example: Driver side temperature 22°C and passenger
side temperature 23°C.
When the DUAL
button is off (LED off), the climate zone of the Climatronic is
synchronised, for example: Driver side temperature 22°C and passenger
side temperature 22°C.
If the DUAL
button is off and the passenger side temperature is changed,
the function is automatically activated. 
Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells
from coming from the outside. – Press the button 
⇒ fig. 113
2 to switch air recirculation
mode on or off. It is switched on if the following symbol appears
in the display .
Air recirculation mode prevents strong odours in the ambient air from enter-
ing the vehicle interior, for example when passing through a tunnel or in a
traffic jam. With low outside temperatures, the air recirculation increases the effective-
ness of the heating system by heating the air inside the vehicle rather than
the 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 Schedule.
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. 

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 250, Fuses.
WARNING
● Never start or run the engine in unventilated or closed rooms. The ex-
haust fumes contain carbon monoxide, an odourless and colourless poi-
sonous gas. Risk of fatal accidents. Carbon monoxide can cause loss of
consciousness. It can also cause 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 263, 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 gear 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. 117 1
. The indicator
lamp  will light for engine pre-heating.
– When the warning lamp turns off, turn the 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 263.
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 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 the engine after refuelling with diesel fuel. This is
because the system must eliminate air first. 
