– Use the air distribution control to guide the flow of air in the required direction: (to the windscreen), (to the upper
body), (to the foot well) and (to the windscreen and to the
foot well).Heating system
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 syst em cannot be switched on, this may be caused by
the following reasons:
•
The engine may not be running.
•
The blower is switched off.
•
The ambient air temperature is lower than +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 quali-
fied workshop.
Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells from entering the vehicle.

Tips and Maintenance
Te c h n i c a l D a t a
•
Adjust the driver seat or steering wheel so that there is a distance of at
least 25 cm between the steering wheel and your chest ⇒page 150,
fig. 113 . 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. 114 .
For example:•
when driving with snow chains,
•
when driving in deep snow or on loose surfaces,

when rocking the vehicle backwards and forwards to free it from mud, for
example.
You should press the button to switch the ESP back on when you no longer
need wheel spin.
The TCS and EDL are also switched off if the ESP is switched off. That is to say,
these systems are not available while ESP is not activated.
When does the button light up or flash?
•
It lights up when the ignition is switched on and should go out again after
about 2 seconds.
•
It will start flashing to indicate that ESP is counteracting an unstable
driving condition.
•
It will light up continuously if there is a malfunction in the ESP.
•
It will light up continuously if the ESP is switched off.
WARNING
•
The electronic stabilisation program (ESP) cannot defy the laws of
physics. This should be kept in mind, particularly on slippery and wet
roads and when towing a trailer.
•
Always adapt your driving style to suit the condition of the roads and
the traffic situation. Do not let the extra safety afforded by ESP tempt you
into taking any risks when driv ing, this can cause accidents.
•
Please refer to the corresponding warning notes on ESP in ⇒page 169,
“Intelligent technology”.

Tips and Maintenance
Te c h n i c a l D a t a
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.

– 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.After starting a very hot engine, you may need to press the accelerator briefly.
When starting from cold, the engine ma y 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 the engine does not start immediately, switch off the starter after about
10 seconds and try again after about half a minute. If the engine still does not
start, the fuel pump fuse should be checked ⇒page 232, “Fuses”.
WARNING
•
Never start or run the engine in un ventilated or closed rooms. The
exhaust fumes contain carbon mono xide, 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 av oid high engine speeds, driving at
full throttle and over-loading the 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 248, “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 engine. 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
the correct code.– Move the gear lever to the ne utral 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 the starting position.
– Turn the ignition key to position ⇒page 152, fig. 115 . The
indication lamp

will light for engine pre-heating.
– When the warning lamp goes out, 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 from cold, the engine 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 ⇒page 248.

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 81 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 248, “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 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 152, fig. 115 .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.
