Air conditioning
● The air conditioner operates most effectively with the windows and the
sliding/tilting sunroof* closed. However, if the temperature inside the vehi-
cle 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.
● At low outside temperatures the compressor switches off automatically.
The AUTO
button cannot be switched on either.
● 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, a Technical Service should be consulted to check the
system.
● To ensure correct operation, the grilles on both sides of the screen must
not be obstructed
● When the engine is under extreme strain, switch off the compressor for a
moment. 

Safety Electronic Stability Control (ESC)*
The ESC helps make driving safer in extreme driving condi-
tions.
Fig. 106 Detailed view of the dash panel: ESC switch.The Electronic Stability Control (ESC) contains the electronic differential lock
(EDL) and the traction control system (ASR). The ESC works together with
the ABS. Both control lamps will light up if the ESC or ABS systems are faul-
ty.
The ESC system is started automatically when the engine is started.
The ESC system is always active and cannot be switched off. The ESC switch
only switches the ASR off.
WARNING
● Do not forget that the Electronic stability control ESC 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. The greater safety provided by the ESC should not
encourage you to run any risks.
● Please refer to the corresponding warning notes on ESC in
⇒ page 168, Intelligent technology.

.
Switching the ignition or the glow plug system on 2
Turn the ignition key to this position and release it. If the key cannot be
turned or it is difficult to turn from position 1 to position 2, move the
steering wheel from one side to the other until it is released.
Starting 3
The engine is started when the key is in this position. Electrical components
with a high power consumption are switched off temporarily.
Every time the vehicle is started again, the ignition key must be turned to
position 1
. The
repetitive start prevention lock of the ignition prevents
possible damage to the starter motor if the engine is already running.
WARNING
● The ignition key must NOT be removed from the lock until the vehicle
comes to a standstill. Otherwise, the steering could be immediately
blocked- Risk of accident!
● Always remove the key from the ignition when leaving the vehicle,
even for a short period. This is especially important if children or disa-
bled people are left alone in the vehicle. They could accidentally start the
engine or work electrical equipment such as the electric windows, conse-
quently resulting in an accident.
● Unsupervised use of the keys could start the engine or any electrical
system, such as the electric window. This could result in serious injury.
CAUTION
The starter motor will only work when the engine is stopped (ignition key
position 3
). 
Electronic immobiliser
The electronic immobiliser prevents unauthorised persons
from driving the vehicle.
Inside the key there is a chip that deactivates the electronic immobiliser au-
tomatically when the key is inserted into the ignition.
The electronic 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 its correct
code.
Note
A perfect operation of the vehicle is ensured if genuine SEAT keys are used. 

Driving
Starting and stopping the engine Starting petrol engines
The engine can only be started using a genuine SEAT key
with its correct code.
– Move the gearbox lever to the neutral position and depress the
clutch pedal thoroughly and hold it in this position for the start-
er to turn the engine on.
– Turn the ignition key to the starting ⇒ page 145 position.
– Let go of the ignition key as soon as the engine starts; the start-
er motor must not run on with the engine.
After starting a very hot engine, you may need to slightly press down the ac-
celerator.
When starting a very cold engine, it may be a little noisy for the first few sec-
onds 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 the starter off after 10 sec-
onds and try again after half a minute. If the engine still does not start, the
fuel pump fuse should be checked ⇒ page 231, Fuses.
WARNING
● Never start or run the engine in unventilated or closed rooms. The ex-
haust gases contain carbon monoxide, an odourless and colourless poi-
sonous gas. Risk of fatal accidents. Carbon monoxide can cause loss of
consciousness. It can also 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. 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 fol-
low the instructions in ⇒ page 248, Jump-starting.
For the sake of the environment
Do not warm-up the engine by running the engine with the vehicle station-
ary. Start off immediately, driving gently. This helps the engine reach oper-
ating temperature faster and reduces emissions. 

– Let go of the ignition key as soon as the engine starts, the start-
er 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 sec-
onds 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 248.
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 goes out.
Starting the 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 minute) to start a diesel engine after refuelling. This is because
the fuel system must eliminate air first.
WARNING
● Never start or run the engine in unventilated or closed rooms. The ex-
haust gases contain carbon monoxide, an odourless and colourless poi-
sonous gas. Risk of fatal accidents. Carbon monoxide can cause loss of
consciousness. It can also 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. 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 fol-
low the instructions in ⇒ page 248, Jump-starting.
For the sake of the environment
Do not warm-up the engine by running the engine with the vehicle station-

Driving
temperature increases due to the heat accumulated in the engine compart-
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 en-
gine switched off, more strength is needed to brake. As normal brake op-
eration cannot be performed, risk of accidents and serious injury may ex-
ist.
● The steering lock can be immediately blocked once the key is re-
moved from the ignition. The vehicle cannot be steered. 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. Driving with LPG*Fig. 108 Centre console:

WARNING
LPG is a highly explosive and inflammable substance. It may cause se-
vere burns and other injury.
● Due care must be taken to avoid any risk of fire or explosion.
● When parking the vehicle in a closed area (for example in a garage),
make sure that there is adequate ventilation, either natural or mechani-
cal, to neutralise the LPG in the event of a leak.
Note
● If frequent short journeys are made, especially when the outside tem-
perature is low, the vehicle will tend to run on petrol more often than on
LPG. Therefore, the petrol tank may empty before the LPG tank.
● The notification LPG mode not possible may be displayed.
