Technical Data
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 ⇒
page 149, fig. 111 button. “AUTO High” is
shown on the radio display (high fan speed).
– Press the button again ⇒page 149, fig. 111 . “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 ad just m en t, excep t as ne ce ssa r y to sui t in di vid ua l pre fe re nces o r
particular circumstances. The compartment 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.

The compartment 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.
If a temperature below 18°C (64°F) is selected, the display switches to LO In
this setting the system runs at maximum cooling output and the temperature
is not regulated. If a temperature above 26°C (80°F) is selected, the display switches to
HI In
this setting the system runs at maximum heating output and the temperature
is not regulated.
Blower
The air flow may be adjusted freely using the control . Always have the
blower running at a low setting to ensure a constant flow of fresh air into the
vehicle. Pushing the button
 to the minimum -1, turns the Climatronic off.
Air distribution
The air distribution is adjusted using the buttons , and . It is also
possible to open and close some of the air vents separately.

Technical Data
When the button is off (LED off), the heating, ventilation and air condi-
tioning system is off.
When the button is off, the heating, ventilation and air conditioning
system is switched off to save fuel. The temperature continues to self-regu-
late. The set temperature can then only be reached if it is higher than the
ambient 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 152, fig. 114 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 temperatures outside, the air recirculation increases the effective-
ness of the heating system by heating the air inside the passenger compart-
ment rather than the air from outside.
With high ambient temperatures, the air recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the passenger
compartment 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 notesThe impurity filter
The impurity filter (a combined particle filter and active carbon filter) serves
as a barrier against impurities in the ambient air, including dust and pollen.
For the air conditioning system to work with maximum efficiency, the pollen
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.

Heating, Ventilation and Air conditioning
154Air 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 conditioning fuse is faulty.•Another fault in the vehicle. Have the air conditioning checked by a qual-
ified workshop.Caution
•If you suspect that the air conditioning is damaged, switch it off with the button to prevent further damage and have it checked by a qualified
workshop.•Repairs to the air conditioning system require specialist knowledge and
special tools. Therefore, we recommend you to take the vehicle to a qualified
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 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 the passenger compartment and is
extracted by slots designed for this purpose. Therefore, do not cover these
slots with items of clothing or other objects.•The air conditioning system operates most effectively with the windows
and the sliding/tilting roof* closed. However, if the vehicle has been over-
heated by sun, the air inside can be cooled quicklier 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.

Driving abroadObservationsTo drive abroad, the following must be taken into consideration:•For vehicles fitted with a catalytic converter ensure that unleaded petrol is
available for the journey. See the chapter “Refuelling”. Automobile organisa-
tions will have information about service station networks selling unleaded
fuel.•In some countries it is possible that a vehicle model is sold under condi-
tions where some spare parts are not available or that the Authorised Service
Centres may only carry out limited repairs.
SEAT importers and distributors will gladly provide information about the
technical preparation of your vehicle and also about necessary maintenance
and repair possibilities.Adhesive strips for headlightsIf you have to drive a right-hand drive vehicle in a left-hand drive country, or
vice versa, the asymmetric dipped beam headlights will dazzle oncoming
traffic.
To prevent dazzling, you must apply stickers to certain parts of the headlight
lenses. Further information is available in your Authorised Service Centre.
In vehicles with self-directing headlights, the rotation system must previ-
ously be disconnected. To do this, please go to a specialist workshop.
