Air conditioning
In manual mode you can adjust the air tem-
perature, air flow and distribution as re-
quired.
Switching on manual mode – To enter manual mode, press one of the
buttons ››› Fig. 120 1 to
5 or press the
air flow control 10 . The selected function is
shown on the radio or navigator display.
Temperature
There are separate temperature selectors for
the left and right sides of the vehicle interior.
The selected temperature is displayed above
the selector. It is possible to select interior
temperatures from +18 °C (+64 °F) to +26 °C
(+80 °F). These are approximate tempera-
tures and the actual temperature may be
slightly higher or lower depending on the
outside ambient conditions.
If you select temperatures below +18 °C
(+64 °F), the indication: LO will appear on the
screen. In this setting the system runs at
maximum cooling output and the tempera-
ture is not regulated.
If a temperature above +26 °C (+80 °F) is se-
lected, the screen will show HI. In this setting
the system runs at maximum heating output
and the temperature is not regulated. Blower
The fan may be adjusted freely using the con-
trols
10 . 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, t urn
s the Climatronic off.
Air distribution
The air distribution is adjusted using the but-
tons  ,
 and
 . It is also possible to
open and close some of the air vents sepa-
rately.
Switching the air conditioning on and off
When the A/C button is on (LED lit), the air
conditioning system is on.
When the A/C button is off (LED off), the air
conditioning system is off.
When the A/C button is off, the air condition-
ing system is switched off to save fuel. The
temperature continues to self-regulate. The
set temperature can only be reached if it is
higher than the outside temperature.
Driver and passenger temperature control
The SYNC button controls the synchronisa-
tion of the 2 Climatronic climate zones.
When the SYNC button is off (LED off), the Cli-
matronic climate zone is personalised. For
example: driver side temperature +22 °C (+72 °F) and passenger side temperature +24
℃
(+23.89 ℃
).
When the S

YNC button is on (LED lit), the Cli-
matronic climate zone is synchronised. For
example: driver side temperature +22 °C
(+72 °F) and passenger side temperature +22
℃ (+22.22 ℃
).
If

the SYNC button is on and the passenger
side temperature is changed, the function is
automatically deactivated.
Air recirculation mode –
Press the button 
››› Fig. 120 5 to
switch air recirculation mode on or off. It is
switched on if the following symbol ap-
pears in the display .
Air recirculation mode prevents strong
odours or contaminated air from the outside
from entering in the vehicle, for example
when passing through a tunnel or in a traffic
jam.
With low outside temperatures, the air recir-
culation increases the effectiveness of the
heating system by heating the air inside the
vehicle rather than the air from outside.
With high outside temperatures, the air recir-
culation increases the effectiveness of the air
conditioning system by cooling the air inside
the vehicle rather than the ambient air. »

Safety

Operation
If the windscreen air output is on and air re-
circulation mode is pressed, this remains ac-
tive. 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 win-
dows 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 bar-
rier against impurities in the outside air, in-
cluding dust and pollen.
For the climate control system to work with
maximum efficiency, the pollution filter must
be replaced at the specified intervals in the
Maintenance Programme.
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 occu-
pants 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 fol-
lowing reasons:
● The engine is not running.
● The A/C button is switched off.
● The outside temperature is lower than ap-
proximately +3 °C (+37 °F).
● 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 specialised work-
shop. CAUTION
● If you suspect that the air conditioner is
damaged, switch it off with the A/C button to
prevent further damage and have it checked
by a specialised workshop.
● Repairs to the air conditioner require spe-
cialist knowledge and special tools. There-
fore, we recommend you to take the vehicle
to a specialised workshop. Note
● If the humidity and temperature outside the
vehicle are high, condensation can drip off
the evaporator in the cooling system and
form a pool underneath the vehicle. This is
normal and does not indicate a leak.
● Keep the air intake slots in front of the
windscreen free of snow, ice and leaves to en-
sure heating and cooling are not impaired,
and to prevent the windows from misting
over.
● The air from the vents flows through the ve-
hicle interior and is extracted by slots de-
signed for this purpose. Therefore, do not
cover these slots with items of clothing or
other objects.
● The air conditioner operates most effective-
ly 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 condition-
ing system leaves residue on the evaporator,
producing a permanent unpleasant odour.
● It is advisable to turn on the air condition-
ing at least once a month, to lubricate the
system gaskets and prevent leaks. If a de-
crease in the cooling capacity is detected, a
Technical Service should be consulted to
check the system. 116

Operation
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 genu-
ine SEAT key with its correct code.
– Move the gearbox lever to the neutral posi-
tion and depress the clutch pedal thor-
oughly and hold it in this position for the
starter to turn the engine on.
– Turn the ignition key to position ›››
Fig. 122
1 . The warning lamp
 will light for en-
gine pre-heating.
– When the lamp turns off, turn the ignition
key to position 2 to start the engine. Do
not press the accelerator.
– Release the ignition key as soon as the en-
gine starts. The starter motor should not
turn at the same time.
When starting a cold engine, it may be a little
noisy for the first few seconds until oil pres-
sure has built up in the hydraulic valve com-
pensators. This is quite normal, and no cause
for concern. If there are problems starting the engine, see
the
››› page 189 .
Glo w p
lug system for the diesel engine
To avoid unnecessary discharging of the bat-
tery, do not use any other major electrical
equipment while the glow plugs are pre-heat-
ing.
Start the engine as soon as the glow plug
warning lamp ››› page 41 goes out.
Starting a 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 mi-
nute) to start a diesel engine after refuelling.
This is because the fuel system must elimi-
nate air first. WARNING
● Never start or run the engine in unventila-
ted or closed rooms. The exhaust gases con-
tain carbon monoxide, an odourless and col-
ourless poisonous gas. Risk of fatal acci-
dents. Carbon monoxide can cause loss of
consciousness and 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. Un-
burnt fuel could enter the catalytic converter
and damage it.
● Before attempting to push-start or tow a ve-
hicle 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 189, Jump-starting. For the sake of the environment
Do not warm-up the engine by running the
engine with the vehicle stationary. You
should drive off as soon as you start the en-
gine. This helps the engine reach operating
temperature faster and reduces emissions. Switching off the engine
–
Stop the vehicle.
– Turn the ignition key to position ›››

Driving
From 1,000 to 1,500 kilometres
– Speeds can be gradually increased to the
maximum road speed or maximum
permissible engine speed (rpm).
During its first few hours of running, the in-
ternal friction in the engine is greater than
later on, when all the moving parts have bed-
ded in. For the sake of the environment
If the engine is run in gently, its life will be in-
creased and its oil consumption reduced. Environmental friendliness
Environmental protection is a top priority in
the design, choice of materials and manufac-
ture of your new SEAT.
Constructive measures to encourage
recycling
● Joints and connections designed for easy
dismantling
● Modular construction to facilitate disman-
tling
● Increased use of single-grade materials.
● Plastic parts and elastomers are marked in
accordance with ISO 1043, ISO 11469 and
ISO 1629. Choice of materials
●
Use of recycled materials.
● Use of compatible plastics in the same part
if its components are not easily separated.
● Use of recycled materials and/or materials
originating from renewable sources.
● Reduction of volatile components, includ-
ing odour, in plastic materials.
● Use of CFC-free coolants.
Ban on heavy metals, with the exceptions
dictated by law (Annex II of ELV Directive
2000/53/EC): cadmium, lead, mercury, hexa-
v al
ent chromium.
Manufacturing methods
● Reduction of the quantity of thinner in the
protective wax for cavities.
● Use of plastic film as protection during ve-
hicle transport.
● Use of solvent-free adhesives.
● Use of CFC-free coolants in cooling sys-
tems.
● Recycling and energy recovery from resi-
dues (RDF).
● Improvement in the quality of waste water.
● Use of systems for the recovery of residual
heat (thermal recovery, enthalpy wheels,
etc.).
● Use of water-soluble paints. Catalytic converter To maintain the useful life of the catalytic
converter
– Use only unleaded petrol with petrol en-
gines, as lead damages the catalytic con-
verter.
– Do not let the fuel get too low in the tank.
– For engine oil changes, do not replenish
with too much engine oil ››› page 168, Top-
ping up engine oil .
– Never tow the vehicle to start it, use jump
leads if necessary ›››
page 189.
If you notice misfiring, uneven running or
loss of power when the vehicle is moving, re-
duce speed immediately and have the vehi-
cle inspected at the nearest specialised
workshop. In general, the exhaust warning
lamp will light up when any of the described
symptoms occur ›››
page 35 . If this happens,
u nb

urnt fuel can enter the exhaust system
and escape into the environment. The cata-
lytic converter can also be damaged by over-
heating. WARNING
The catalytic converter reaches very high
temperatures! Risk of fire!
● Never park where the catalytic converter
could come into contact with dry grass or
flammable materials under the vehicle. » 131

Operation
●
Do not apply additional underseal or anti-
corrosion coatings to the exhaust pipes, cata-
lytic converter or the heat shields on the ex-
haust system. These materials could catch
fire when the vehicle is being driven. CAUTION
Never run the fuel tank completely dry be-
cause the irregularity of the fuel supply may
cause ignition problems. This allows unburnt
fuel to enter the exhaust system, which could
cause overheating and damage the catalytic
converter. For the sake of the environment
Even when the emission control system is
working perfectly, there may be a smell of
sulphur from the exhaust gas under some
conditions. This depends on the sulphur con-
tent of the fuel used. Quite often the problem
can be solved by changing to another brand
of fuel. Diesel engine particulate filter*
Fig. 130
Vehicle data sticker on back cover of
the Maintenance Programme. Your vehicle is fitted with a DPF (Diesel partic-
ulate filter) if the vehicle data sticker (back
cover of the “Maintenance Programme)” lists
the PR code 7GG or 7MG
››› Fig. 130 .
The die sel
engine particulate filter eliminates
most of the soot from the exhaust gas sys-
tem. Under normal driving conditions, the fil-
ter cleans itself. If this is not possible (for ex-
ample, multiple short trips) the filter will be
obstructed by soot and  the diesel engine
particulate filter warning lamp will light up.
This does not represent a fault, it is a warning
that indicates that the filter has not been
able to regenerate automatically and that you
must perform a cleaning cycle, as indicated
in ››› page 41
. WARNING
● The diesel engine particulate filter may
reach extremely high temperatures; the vehi-
cle should be parked so that the exhaust pipe
does not come into contact with flammable
materials underneath the vehicle. Otherwise
there is a risk of fire. CAUTION
● Your vehicle is not designed to use biodie-
sel fuel. Never, under any circumstances re-
fuel with biodiesel. The use of biodiesel fuel
could damage the engine and the fuel sys-
tem. The addition of biodiesel to diesel by
the diesel producer in accordance with stand-
ard EN 590 is authorised and will not cause
damage to the engine or the fuel system.
● Using diesel fuel with a high sulphur con-
tent may significantly reduce the useful life of
the diesel particulate filter. Your Technical
Service will be able to tell you which coun-
tries have diesel with a high sulphur content. Economical and environmentally
friendly driving
Fuel consumption, environmental pollution
and wear to the engine, brakes and tyres de-
pends in large part on your driving style. By
adopting an economical driving style and an-
ticipating the traffic situation ahead, you can
easily reduce fuel consumption by 10-15%.
132

Operation
and 120 km/h (75 mph) your vehicle will use
about 12% more fuel as a result of the extra
wind resistance caused by the roof rack even
when it is not in use.
Save electricity
The engine activates the alternator, which
produces electricity. With the need for elec-
tricity, fuel consumption is also increased.
Because of this, always turn off electrical de-
vices when you do not need them. Examples
of devices that use a lot of electricity are: the
fan at high speeds, the rear window heating
or the seat heaters*. Note
● If you vehicle has Start-Stop, it is not rec-
ommended t o sw
itch this function off.
● It is recommended to close the windows
when driving at more than 60 km/h
● Do not drive with your foot resting on the
clutch pedal,, as the pressure can make the
pl

ate spin, more fuel will be used and it can
burn the clutch plate lining, causing a serious
fault.
● Do not hold the vehicle on a hill with the
clutch, use the foot brake or hand brake, us-
ing the latter to start. The fuel consumption
will be lower and you will prevent the clutch
plate from being damaged.
● On descents, use the engine brake, chang-
ing to the gear that is more suitable for the slope. Fuel consumption will be “zero” and
the brakes will not suffer.
