Air recirculation mode
⇒page 140, fig. 106 prevents strong odours in
the outside air from entering the vehicle interior, for example when passing
through a tunnel or in queuing traffic.
With low ambient temperatures, the air recirculation increases the effective-
ness of the heating system by heating the air inside the passenger compart-
ment rather than the ambient air.
With high ambient temperatures, the air recirculation increases the effective-
ness of the air cooling system by cooling the air inside the passenger
compartment rather than the ambient air. For reasons of safety, air recirculation is
not possible when the control for air
distribution is set to the windscreen setting .
WARNING
In air recirculation mode, no ambient air enters the vehicle interior. If the
air conditioning system is switched off, the windows can quickly mist over.
Therefore, you should never leave the air recirculation mode switched on
for longer periods, as this increases the risk of an accident.
2C-Climatronic*Control switches
The controls allow separate adjustment of air conditioning settings for the left and right.

– Press temperature selectors to set the desired temperatures for
the left and right sides of the interior. We recommend 22°C
(72°F).A comfortable interior climate is quickly reached when a temperature of
+22° C (72° F) is set in automatic mode. It can be changed as necessary to
suit individual preferences or particular circumstances. It is possible to select
interior temperatures from +16° C (6 1° F) to +29.5° C (86° 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 level fully automatically. The
temperature of the air supplied to the interior, the blower speed and the air
distribution are regulated automatically. The system also allows for the effect
of strong sunlight, so there is no n
eed for manual adjustment. Therefore,
automatic mode provides the best comfort for the vehicle occupants in virtu-
ally all conditions throughout the year.
Automatic mode is switched off whenever an adjustment is made using the
buttons for the air distribution, air flow or . The temperature will
continue to be regulated within the parameters manually selected by the
user.Manual mode
In manual mode you can adjust the air temperat ure, air flow and distribution as required.Switching on manual mode

General notesThe pollen filter
The pollen 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 with very high
levels of air pollution, the pollen filter must be changed more frequently than
stated in the Service Schedule.
Caution
•
If you suspect that the air conditioner is damaged, switch off the air condi-
tioner with 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 that you take the vehicle to a quali-
fied workshop should problems occur.Note
•
If the humidity and temperature outside the vehicle are high, condensa-
tion can drip off the evaporator in the cooling system and form a pool under-
neath 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 is not impaired, and to prevent the
windows misting over.
•
The air from the vents flows through the passenger compartment and is
extracted by slots designed for this purpose. Do not cover these slots with
articles of clothing or other objects.
•
The air conditioning system operates most effectively with the windows
and the sliding/tilting roof* closed. However, if the sun has heated up the
vehicle, the air inside can be cooled more quickly by opening the windows for
a short period.
•
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.

•
Adjust the driver seat or steering wheel so that there is a distance of at
least 25 cm between the steering wheel and your breast bone ⇒page 146,
fig. 110 . If you fail to observe the minimum distance, the airbag will not
protect you. Risk of fatal injury.
•
If your physical constitution prevents you from maintaining the
minimum distance of 25 cm, contact an Authorised Service Centre. The
Authorised Service Centre will help you decide if special specific modifica-
tions are necessary.
•
If you adjust the steering wheel so th at it points towards your face, the
driver airbag will not protect you prop erly in the event of an accident. Make
sure that the steering wheel points towards your chest.
•
When driving, always hold the steering wheel with both hands on the
outside of the ring at the 9 o'clock and 3 o'clock positions. Never hold the
steering wheel at the 12 o'clock position, or in any other manner (e.g. in
the centre of the steering wheel, or on the inside of the rim). In such cases,
you could receive severe injuries to the arms, hands and head.
SafetyElectronic stabilisation programme (ESP)*
ESP helps make driving safer in certain situations.The Electronic Stabilisation Program (ESP ) contains the electronic differential
lock (EDL) and the traction control system (TCS). The ESP function works in
conjunction with the ABS. Both warning la mps will light up if the ESP or ABS
systems are faulty.
The ESP is started automatically when the engine is started.
In specific circumstances where you requ ire less traction, you can switch off
the ESP by pressing button ⇒fig. 111 .
For example:•
When driving with snow chains,
•
when driving in deep snow or on loose surfaces,

Starting
The engine is started when the key is in
this position. Electrical components
with a high power consumption are switched off temporarily.
Each time that the vehicle must be started, the ignition key must be turned to
the position . The repetitive start prevention lock of the ignition prevents
possible damage to the starter motor if the engine is already running.
WARNING
•
Wait for the vehicle to come to a standstill before removing the ignition
key from the lock. The steering lock could be activated immediately - Risk
of accident!
•
Always remove the key from the ignit ion lock when leaving the vehicle,
even if you only intend to be gone for a short period. This is especially
important if you must leave children or disabled people in the vehicle, they
could accidentally start the engine or work electrical equipment such as
the windows possibly resulting in an accident.
•
Unsupervised use of the keys could result in the engine being started
or electrical systems, such as the electric windows, being used. This can
result in serious injury.Caution
The starter motor will only work when the engine is stopped (ignition key
position ).
Electronic immobiliser
The immobiliser prevents unauthorised persons from driving
the vehicle.Inside the key there is a chip that deactivates the electronic immobiliser auto-
matically when the key is inserted into the ignition.
The immobiliser will be activated again automatically as soon as you pull the
key out of the ignition lock.
The engine can only be started using a genuine SEAT key with the correct
code.
Note
The vehicle cannot be operated properly if you do not have a genuine SEAT
key.Starting and stopping the engineStarting petrol engines
The engine can only be started using a genuine SEAT key with
the correct code.– Move the gear lever to the neutral position and depress the clutch pedal fully and hold it in this position, the starter will then
only have to turn the engine.
– Turn the ignition key to position ⇒page 148 to start the engine.

Glow plug system for the diesel engine
To avoid unnecessary load on the battery, do not use any other major elec-
trical equipment while the
glow plugs are pre-heating.
Start the engine as soon as the glow plug warning lamp ⇒page 80 goes out.
Starting the engine after the fuel tank has been completely run dry
If the fuel tank has been completely ru n dry, it may take longer than normal
(up to one minute) to start the engine af ter refuelling with diesel fuel. This is
because the system must eliminate air first.
WARNING
•
Never start or run the engine in unventilated 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 avo id high engine speeds, driving at
full throttle and over-loading th e engine. Risk of engine damage.
•
The vehicle should not be pushed or towed for more than approximately
50 metres to start the engine. Fuel could enter the catalytic converter and
damage it.
•
Before attempting to push-start or tow a vehicle to start it, you should first
try to start it using the battery of another vehicle. Note and follow the instruc-
tions ⇒ page 240, “Jump-starting”.
For the sake of the environment
Do not warm-up the engine by running th e engine with the vehicle stationary.
You should drive off as soon as you start the engine. This helps the engine
reach operating temperature faster and reduces emissions.Switching off the engine– Stopping the engine.
– Turn the ignition key to position ⇒page 148, fig. 112 .After the engine is switched off the radiator fan may run on for up to 10
minutes, even if the ignition is switched of f. It is also possible that it will turn
itself on once more if the temperature of the coolant increases due to the
elimination of built up heat in the engine compartment or if this is heated due
to prolonged exposure to the heat of the sun.
WARNING
•
Never switch off the engine until the vehicle is stationary.
•
The brake servo works only when the engine is running. You will need
more strength to brake the vehicle when the engine is switched off. As you
cannot brake in the normal manner, there is a greater risk of accidents and
serious injury.
•
The steering lock can engage immediately when the key is removed
from the ignition lock. The vehicle cannot be steered. Risk of accident.

•
Depending on weather conditions, it may become extremely hot or cold
inside the vehicle. This can be fatal.
Acoustic parking aid system*Rear parking aid
The parking aid system will use an acoustic signal to warn of
the approach of any object towards the rear of the vehicle.Description
The acoustic parking aid system will measure the distance between the rear
of the vehicle and any possible obstacle using four ultrasonic sensors located
on the rear bumper. The measuring range of the sensors starts at approxi-
mately and depending on the nature of the obstacle at a distance of:•
side of the rear bumper: 0.8 m
•
centre of the rear bumper: 1.3 m
Activation
The system is activated by engagement of the reverse gear. A brief acoustic
signal confirms the activation and correct function of the system.
Reversing
The distance warning will begin as soon as an obstacle is detected by the
system. The frequency of the bleeps emitted by the system will increase
rapidly as the vehicle approaches the obstacle.
Within a short distance of about 25 cm, a continuous signal sounds (stop
signal). The driver should not reverse any further. Trailer towing
For vehicles fitted with a tow bar by the manufacturer, the parking aid system
will not be activated by the engagement of the reverse gear when pulling a
trailer, as the trailer's electric conne
cter will be plugged into the vehicle.
To avoid system malfunctions, when not driving with a trailer, remove the
trailer hitch.
Possible faults
If a continuous bleep sounds for some seconds when the reverse gear is
engaged, this indicates that there is a fault in the parking aid system.
If the fault continues until the ignition is turned off, the acoustic signal
warning of the fault will not be emitted every time the system is reactivated
(by engaging the reverse gear). Thus, the system ready indication will not
sound either. Have the fault repaired by an Authorised Service Centre as soon
as possible.
If there is no ready signal or no acoustic warning signal then the parking aid
loudspeaker is faulty and may not warn of obstacles.
To ensure that the system works properly, the sensors must be kept clean and
free of ice and snow.
WARNING
•
The sensors have blind spots in which obstacles may not be detected.
•
Always look out for small children and animals because the system will
not always detect them. Always pay attention when reversing to avoid acci-
dents.
•
The parking aid is not a replacement for driver awareness. The driver
must take full responsibility for parking and other manoeuvres.
