be able to lock and unlock the vehicle using the remote control
⇒ page 109.
● The new battery must be of the same type as the original. 
Electronic immobiliser
The electronic immobiliser is designed to prevent unauthor-
ised persons from starting up the vehicle.
There is an electronic chip inside the key which automatically deactivates
the immobiliser when the key is inserted into the ignition lock. The electron-
ic immobiliser is enabled automatically when the ignition key is removed
from the ignition lock after coming to a stop.
If an uncoded key is used, the message SAFE will appear in the trip recorder
display.
Note
● The engine can only be started using an original SEAT key with the cor-
rect code.
● It may not be possible to start the engine with the key if there is another
ignition key from a different make of vehicle on the same key tab. 
Central locking Description
The central locking system enables you to lock and unlock
all the doors, the rear lid and the tank flap together.The central locking system on your vehicle locks and unlocks all the doors
and the tank flap simultaneously. The rear lid is unlocked when the vehicle
is opened. However, the handle must be used to open it. The vehicle can be
locked and unlocked using the remote control ⇒ page 108 or by turning the
key in the lock in the driver door.
The windows can also be centrally opened or closed using the central lock-
ing system ⇒ page 114. The sunroof* can be closed but not opened using
the central locking system.
The central locking system is combined with an anti-theft security system.
If the vehicle is locked with the key from the outside, the interior opening
levers stop working, which prevents unauthorised persons from entering
the vehicle.
Should the central locking system fail to work, you can activate all the locks
individually. 

The remote control transmitter and the battery are integrated into the han-
dle of the key. The receiver is in the interior of the vehicle. The maximum
range depends on different circumstances. The range is reduced when the
battery starts to lose power.
The remote control incorporates a foldaway key that can be used to manual-
ly lock or unlock the vehicle, as well as to start the engine. If the receiver has been repaired or replaced, or if a replacement key is
used, the system will need re-programming by a specialised workshop. Only
then will you be able use the remote control again.
The remote control meets all relevant authorisation requirements and has
been approved by the Federal Approvals Office for Telecommunications of
the Federal Republic of Germany. All components are marked in accordance
with the current legal requirements. This certification forms the basis for of-
ficial approval for use in other countries.

● The remote control is automatically disabled when the ignition is switch-
ed on.
● The function of the remote control may be impaired by interference from
other nearby radio signals (e.g. from a mobile phone or TV transmitter) if
these are in the same frequency range. 

ularly on short journeys, will increase the load on the battery. To make sure
the battery is always sufficiently charged, occasionally drive longer distan-
ces.
● If the fog lights have been switched on by the coming home and leaving
home functions, they will always be switched off when you switch on the ig-
nition.

.
Switching on the ignition/pre-heating glow plugs 2
If the key is difficult to turn in the lock, move the steering wheel (to take the
load off the steering lock mechanism) until the key turns freely. In the case
of vehicles with a diesel engine, the key is turned to this position to preheat
the glow plugs.
Starting the engine 3
The engine is started in this position. Electrical components with a high
power consumption are switched off temporarily.
After the engine has started, the ignition key returns to position 2
by itself.
The ignition key has to be turned back to position 1
before re-starting the
engine. The starter inhibitor in the ignition lock prevents the starter motor
from engaging when the engine is running, as this could cause damage.
Switching off the ignition 1
Turn the ignition key to this position.
WARNING
● Never remove the ignition key until the vehicle is stationary! Other-
wise the steering lock could engage suddenly, which could cause an acci-
dent.
● Always take the key with you when leaving the vehicle, even if you
only intend to be gone for a short time. This is particularly important if
there are children in the vehicle, as they might otherwise be able to start
the engine or use power-operated equipment (e.g. the electric windows),
which could cause injuries.
Note
● If the battery has been disconnected and then reconnected, it will be
necessary to leave the key in position 2
for about 5 seconds before start-
ing the engine.
● Vehicles with automatic gearbox: After switching off the ignition, you
can only remove the ignition key if the selector lever is in position “P” (park-
ing lock). The selector lever is locked after the ignition key has been re-
moved. 
