Opening and closing
● Mo v
e the g
ear lever to position P (if the ve-
hicle has automatic gearbox), since other-
wise the vehicle cannot be locked.
● Close the door.
● Push the central locking button  on the
remote c
ontrol and touch the locking sensor
surface ››› Fig. 136 B on the driver door han-
dl e onc
e w

ithin the following 5 seconds. Do
not grip the door handle, otherwise the vehi-
cle will not lock. Deactivation is also possible
if the vehicle is locked through the driver’s
door lock.
● To check that the function has been deacti-
vated, w
ait at least 10 seconds, grip and pull
on the door handle. The door should not
open.
The next time the door can only be unlocked
via the remote control or the lock cylinder.
The next time the door is locked/unlocked,
Keyless Access will be active again.
Convenience functions
To close all the electric windows and the sun-
roof using the convenience function, keep a
finger for a few seconds on the locking sen-
sor surface B (arrow) of the door handle un-
ti l
the w

indows and roof have closed.
The doors opened by touching the sensor
surface of the door handle depend on the
settings that have been activated in the info-
tainment system with the  button and theSETTINGS and
Openin
g and c
lo
sing function but-
t on
s. CAUTION
The sensor surfaces on the door handles
cou l

d engage if hit with a water jet or high
pressure steam if there is a valid vehicle key
in the proximity. If at least one of the electric
windows is open and the sensor surface B (arrow) on one of the handles is activated
continuou
s

ly, all windows will close. Note
● If the v

ehicle battery has little or no charge,
or the vehicle key battery is almost or entire-
ly out of charge, you will probably not be able
to lock or unlock the vehicle with the Keyless
Access system. The vehicle can be unlocked
or locked manually ››› page 97.
● To control the proper locking of the vehicle,
the rele
ase function is disabled for approx. 2
seconds.
● If the message Keyless access system
faulty is di

splayed on the screen of the
dash panel, abnormalities may occur in the
operation of the Keyless Access system. Con-
tact a specialised workshop. SEAT recom-
mends visiting a SEAT dealership for this.
● Depending on the function set on the info-
tainment sy
stem for the mirrors, the exterior
mirrors will unfold and the surround lighting
will come on when unlocking the vehicle us-
ing the sensor surface on the driver and pas-
senger door handles ››› page 150. ●
If ther e i

s no valid key inside the vehicle or
the system fails to detect one, a warning will
display on the dash panel screen. This could
happen if any other radio frequency signal in-
terferes with the key signal (e.g. from a mo-
bile device accessory) or if the key is covered
by another object (e.g. an aluminium case).
● If the sensors are very dirty, e.g. have a lay-
er of sa
lt, the correct functioning of the sen-
sors on the door handles may be affected. In
this case, clean the vehicle.
● If the vehicle is equipped with an automatic
gearbo
x, it may only be locked in the gear
stick is in position P. Anti-theft security system (Safelock)*
The following message is displayed on the in-
s
trument
p

anel to remind the driver that
when the vehicle is closed from the outside,
the anti-theft security system is switched on.  Do not forget the Safelock.
Please see Instruction Manual . The
vehicle cannot be opened from inside. This
makes it more difficult for unauthorised per-
sons to break into the vehicle ››› in De-
s c
ription on p

age 125.
The anti-theft security system can be switch-
ed off each time the vehicle is locked:
● Turn the key a second time to the lock posi-
tion, in the door lock, w

ithin two seconds. If »

completely).
● 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 vibration of a mobile phone left inside
the vehic
le 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
all the doors are closed (including the rear
lid). Deactivating the vehicle interior moni-

ow system* When the vehicle is locked, the alarm will be
trigg
er

ed if movements are detected in the
interior (e.g. by animals) or if the vehicle's in-
clination is changed (e.g. during transport).
You can prevent the alarm from being trig-
gered accidentally by switching off the vehi-
cle interior monitoring and/or tow-away pro-
tection.
● To switch off the interior monitoring and
to w-

away protection, switch off the ignition
and, using the Infotainment system, select:  button >

tion are switched off until the next time the
door is opened.
If the anti-theft security system (Safelock)*
