156The 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 button ⇒page 154, fig. 110 . “AUTO High” is
shown on the radio display (high fan speed).
– Press the button again ⇒page 154, 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 almost
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
people.

then only be reached if it is higher than the outside temperature.
Driver and passenger temperature control
The button controls the synchronisation of the 2 Climatronic climate
zones.
When the 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 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 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 ⇒page 157, fig. 113 to switch air recir-
culation 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
entering 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
connected.
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 notesPollution 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.
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 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 special-
ised workshop.Caution
•If you suspect that the air conditioner is damaged, switch it off with the button 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 work-
shop.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 puddle
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 th e vehicle interior and is extracted
by slots designed for this purpose. 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 temperature inside the vehicle
is excessive because of the sun, the air inside can be cooled faster by opening
the windows for a short time.•Do not smoke while air recirculation mode is on, as smoke drawn into the
air conditioning system leaves a residue on the evaporator, producing a
permanent unpleasant odour.•It is advisable to connect the air conditioning at least once a month, to
lubricate the system gaskets and prevent leaks. If a decrease in the cooling
capacity is detected, an Authorised Service Centre should be consulted to
check the system.

164If the engine does not start immediately, switch the starter off after
10 seconds and try again after half a minute. If the engine still does not start,
the fuel pump fuse should be checked ⇒page 254, “Fuses”.
WARNING
•Never start or run the engine in un ventilated or closed rooms. The
exhaust fumes contain carbon monoxide, an odourless and colourless
poisonous 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 follow
the instructions in ⇒page 267, “Jump-starting”.For the sake of the environment
Do not warm-up the engine by running the engine with the vehicle stationary.
Start off immediately, driving gently. This helps the engine reach operating
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 starter
to turn the engine on.
– Turn the ignition key to the starting position.
– Turn the ignition key to position ⇒page 162, fig. 117 . The
indicator lamp
D will light for engine pre-heating.
– When the warning lamp turns off, turn the key to position to
start the engine. Do not press the accelerator.
– Let go of the ignition key as soon as the engine starts, the starter 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
seconds 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 267.
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.

ment or due to its prolonged exposure to solar radiation.
WARNING
•Never switch the engine off until the vehicle is completely stationary.•The brake servo works only when the engine is running. With the
engine switched off, more strength is needed to brake. As normal brake
operation cannot be performed, risk of accidents and serious injury may
exist.•The steering lock can be immediately blocked once the key is removed
from the ignition. The steering wheel cannot be turned. Risk of accident.Caution
When the engine has been running under a heavy load for a long period, heat
can accumulate in the engine compartment and cause engine damage. For
this reason, you should idle the engine for approx. 2 minutes before you
switch it off.
