 page 11
The vehicle can be locked and unlocked via
the central locking system. There are several
methods, depending on the vehicle equip-
ment:
● key with remote control ››
›

page 118 ,
● lock on driver door (emergency opening
›››
 page 11) or
● interior central locking switch ›››

page 119.
Unlocking one side of the vehicle only
When you lock the vehicle with the key, the
doors and the rear lid are locked. When you
open the door, you can either unlock only the
driver door, or all the vehicle doors. To select
the required option, use Easy Connect*
››› page 119.
Automatic locking (Auto Lock)*
The Auto Lock function locks the doors and
the rear lid when the vehicle exceeds a speed
of about 15 km/h (10 mph). The vehicle is unlocked again when the igni-
tion key i

s removed. Alternatively, the vehicle
can also be unlocked via the central locking
switch or by pulling one of the inside door
handles. The Auto Lock function can be
switched on and off on the sound system or
on the Easy Connect* system ››› page 119.
In the event of an accident in which the air-
bags inflate, the doors will be automatically
unlocked to facilitate access and assistance.
Anti-theft alarm system*
If the anti-theft alarm system senses interfer-
ence with the vehicle it triggers an audible
and visible alarm.
The anti-theft alarm system is automatically
switched on when locking the vehicle. It
switches off when the vehicle is unlocked
from a distance.
When the driver door is unlocked with the
key, you should switch on the ignition within
15 seconds. Otherwise the alarm will be trig-
gered. On some export versions, the alarm is
triggered immediately when you open a door.
To deactivate the alarm, press the button  on the remote control key, or switch on the
ignition. Af
t
er a c

ertain time, the alarm will
automatically switch off.
Switch off the vehicle interior monitoring and
tow-away protection if you wish to prevent the alarm from being triggered accidentally
›››
page 123.
Turn signals
The turn signals will flash twice when the ve-
hicle is unlocked and once when the vehicle
is locked.
If it does not flash, this indicates that one of
the doors, the rear lid or the bonnet is not
closed correctly.
Accidental lock-out
The central locking system prevents you from
being locked out of the vehicle in the follow-
ing situations: ● If the driver door is open, the vehicle can-
not be lock
ed with the central locking switch
››› page 119.
Lock the vehicle with the remote control key,
when all the doors and the rear lid have been
closed. This prevents the accidental locking
of the vehicle. WARNING
Do not leave anyone (especially children) in
the v ehic

le if it is locked from the outside and
the anti-theft security system* is enabled, as
the doors and windows cannot then be
opened from the inside. Locked doors could
delay assistance in an emergency, potentially
putting lives at risk. 116

Operation
The vehicle keys or new spare keys can be
o bt
ained fr
om a SEAT Official Service, a spe-
cialised workshop or an approved key service
qualified to create this kind of key.
New keys or spare keys must be synchron-
ised before use ››› page 121. CAUTION
All of the vehicle keys contain electronic com-
ponents. Pr ot

ect them from damage, impacts
and humidity. Note
● Only u

se the key button when you require
the corresponding function. Pushing the but-
ton unnecessarily could accidentally unlock
the vehicle or trigger the alarm. It is also pos-
sible even when you are outside the radius of
action.
● Key operation can be greatly influenced by
overl
apping radio signals close to the vehicle
working in the same range of frequencies, for
example, radio transmitters or mobile tele-
phones.
● Obstacles between the remote control and
the vehic
le, bad weather conditions and dis-
charged batteries can considerably reduce
the range of the remote control.
● If the buttons of the vehicle key are press-
ed ›››

Fig. 131 or ››› Fig. 132 or one of the cen-
tral locking buttons ››› page 119 is pressed
repeatedly in short succession, the central
locking briefly disconnects as protection against overloading. The vehicle is then un-
lock
ed. L

ample, the vehicle is transported
or has to be towed with only one axle on the
ground.
False alarms
Interior monitoring will only operate correctly
if the vehicle is completely closed. Please ob-
serve related legal requirements.
The following cases may cause a false alarm:
● Open windows (partially or fully).
● Panoramic/tilting sunroof open (partially or
compl
etely).
● Movement of objects inside the vehicle,
such a
s loose papers, items hanging from
the rear vision mirror (air fresheners), etc. Note
● If the v

ehicle is relocked and the alarm is
activated without the volumetric sensor func-
tion, relocking will activate the alarm with all
its functions, except the volumetric sensor.
This function is reactivated when the alarm is
switched on again, unless it is deliberately
switched off.
● If the alarm has been triggered by the volu-
metric sensor
, this will be indicated by a
flashing of the warning lamp on the driver
door when the vehicle is opened. The flash is
different to the flash indicating the alarm is
activated. ●
The v ibr

ation of a mobile phone left inside
the vehicle may cause the vehicle interior
monitoring alarm to trigger, as both sensors
react to movements and shakes inside the ve-
hicle.
● If on activating the alarm, any door or the
rear lid i
s open, only the alarm will be activa-
ted. The vehicle interior monitoring and the
anti-tow system will only be activated once
