Opening and closing
To deactivate the alarm, press the button 
on the remote control key, or
switch on the ignition. After a certain 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 95.
Turn signals
The turn signals will flash twice when the vehicle is unlocked and once
when the vehicle is locked.
If the signals do 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 vehi-
cle in the following situations:
● If the driver door is open, the vehicle cannot be locked with the central
locking switch ⇒ page 93.
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 vehicle 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.
Note
● Never leave any valuable items in the vehicle unattended. Even a locked
vehicle is not a safe.
● If the diode on the driver door sill lights up for about 30 seconds when
the vehicle is locked, the central locking system or anti-theft alarm* is not
working properly. You should have the fault repaired at a SEAT Official Serv-
ice or specialised workshop.
● The vehicle interior monitoring of the anti-theft alarm* system will only
function as intended if the windows and the sunroof* are closed. 
Safety FirstOperating instructionsPractical TipsTechnical specifications

95
Opening and closing
The vehicle interior monitoring and anti-tow sensor (tilt sensor) are auto-
matically switched on when the anti-theft alarm is switched on. In order to
activate it, all the doors and the rear lid must be closed.
If you wish to switch off the vehicle interior monitoring and the anti-tow sys-
tem, it must be done each time that the vehicle is locked; if not, they will be
automatically switched on.
The vehicle interior monitoring and the anti-tow system should be switched
off if animals are left inside the locked vehicle (otherwise, their movements
will trigger the alarm) or when, for example, the vehicle is transported or
has to be towed with only one axle on the ground.
False alarms
The interior monitoring only operates correctly if the vehicle is completely
closed. Please observe legal requirements when doing so.
The following cases may cause a false alarm:
● opened windows (partially or fully)
● panoramic/tilting sunroof open (partially or completely).
● movement of objects inside the vehicle, such as loose papers, items
hanging from the rear vision mirror (air fresheners), etc.
Note
● If the vehicle is relocked and the alarm is activated without the volumet-
ric sensor function, 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 volumetric sensor, this will be in-
dicated by a flashing of the warning lamp on the driver door when the vehi-
cle is opened. The flash is different to the flash indicating the alarm is acti-
vated. ●
The vibration of a mobile phone left inside the vehicle may cause the ve-
hicle interior monitoring alarm to trigger, as both sensors react to move-
ments and shakes inside the vehicle.
● If on activating the alarm, any door or the rear lid is open, only the alarm
will be activated. The vehicle interior monitoring and the anti-tow system
will only be activated once all the doors are closed (including the rear lid). 
Deactivating the vehicle interior monitoring and tow-away
protection 1)
Fig. 51 Vehicle interior
monitoring/tow-away
protection button
When the vehicle is locked, the alarm will be triggered if move-
ments are detected in the interior (e.g. by animals) or if the vehi-
cle's inclination is changed (e.g. during transport). You can prevent
the alarm from being triggered accidentally by switching off the ve-
hicle interior monitoring and/or tow-away protection.
– To switch off the vehicle interior monitoring and tow-away pro-
tection, switch off the ignition and press button ⇒ Fig. 51. The
button will light up. 

96Opening and closing
–When the vehicle is locked now, the vehicle interior monitoring
and the tow-away protection are switched off until the next time
the door is opened.
If the anti-theft security system (Safelock)* ⇒  page 86 is switched off, the
vehicle interior monitoring and the tow-away protection are automatically
switched off.
WARNING
Do not leave anyone (especially children) in the vehicle 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.

Emergency locking and unlocking Introduction
The doors, rear lid and panoramic tilting sunroof can be locked manually
and partially opened, for example if the key or the central locking is dam-
aged.
Additional information and warnings:
● Vehicle key set ⇒ page 88
● Central locking and locking system ⇒ page 86
● Rear lid ⇒  page 98
WARNING
Opening and closing doors carelessly can cause serious injury.
● If the vehicle is locked from outside, the doors and windows cannot
be opened from the inside.
● Never leave children or disabled people alone in the car. They could
be trapped in the car in an emergency and will not be able to get them-
selves to safety.
● Depending on the time of the year, temperatures inside a locked and
closed vehicle can be extremely high or extremely low resulting in seri-
ous injuries and illness or even death, particularly for young children.
WARNING
Getting in the way of the doors and the rear lid is dangerous and can lead
to serious injury.
● Open and close the doors and the rear lid only when there is nobody
in the way.
CAUTION
When opening and closing in an emergency, carefully disassemble compo-
nents and then reassemble them carefully to avoid damage to the vehicle. 

WARNING (Continued)
● The electric windows will work until the ignition has been switched
off and one of the front doors has been opened.
● If necessary, use the safety switch to disable the rear electric win-
dows. Make sure that they have been disabled.
Note
If the window is not able to close because it is stiff or because of an ob-
struction, the window will automatically open again ⇒ page 102. If this
happens, check why the window could not be closed before attempting to
close it again. 

close all the windows and the sliding/tilting sunroof* from the out-
side.

close functions within about 2 metres of the vehicle. To avoid injuries, al-
ways keep an eye on the windows and the sliding/tilting sunroof* when
pressing the button to close them. The windows stop moving as soon as
the button is released.

One-touch opening and closing*
One-touch opening and closing means you do not have to
hold down the button.
Buttons ⇒ Fig. 56 1
, 2, 3 and 4 have two positions for open-
ing windows and two for closing them. This makes it easier to open
and close windows to the desired position.

lected if the roof is closed using convenience closing from outside the vehi-
cle and will have to be re-positioned the next time you drive. 
Roll-back function on panoramic sliding sunroof
The roll-back function can reduce the risk of injury when opening and clos-
ing the panoramic sliding sunroof ⇒ . When the panoramic sliding sun-
roof encounters an obstacle while closing, it rolls back and opens again.
● Check why the panoramic sliding sunroof does not close.
● Try to close the panoramic sliding sunroof again.
● If the panoramic sliding sunroof is still obstructed, it will stop at the cor-
responding position. Next, close the panoramic sliding sunroof without the
roll-back function. 

ised workshop.
WARNING
Closing the panoramic sliding sunroof without the roll-back function may
result in serious injury.
● Always close the panoramic sliding sunroof carefully.
● Make sure that nobody is in the way of the panoramic sliding sunroof,
especially when it is closed without the roll-back function.
● The anti-trap function does not prevent fingers or other parts of the
body getting pinched against the window frame and causing injury.
Note
The anti-trap function is activated if the windows and the panoramic sliding
sunroof are closed from the outside of the vehicle using the ignition key for
convenience closing ⇒ page 101. 
