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

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 »

Opening and closing
● Panor
amic/ti
lting sunroof open (partially or
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-

orin
g and anti-t

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 >

interior monitorin
g and the tow-away protec-
tion are switched off until the next time the
door is opened.
If the anti-theft security system (Safelock)*

Lo a

ding the luggage compartment All luggage and other loose objects must be
saf
ely

secured in the luggage compartment.
Unsecured objects which shift back and forth
could impair the driving safety or driving
characteristics of the vehicle by shifting the
centre of gravity.
– Distribute the load evenly in the luggage
comp ar

tment.
– Place heavy objects as far forward as possi-
ble in the lug

gage compartment.
– Place the heavy objects first.
– Secure heavy objects to the fitted fastening
rings

››› page 167. WARNING
● Loo se lug

gage and other objects in the lug-
gage compartment could cause serious inju-
ries.
● Always stow objects in the luggage com-
partment
and secure them on the fastening
rings. 160

Transport and practical equipment
●
Use s uit
able straps to secure heavy ob-
jects.
● During sudden manoeuvres or accidents,
loose ob
jects can be thrown forward, injuring
vehicle occupants or passers-by. This in-
creased risk of injury will be further increased
if a loose object is struck by an inflating air-
bag. If this happens, objects may shoot out-
ward like a missile. Risk of fatal injury.
● Please note that the centre of gravity may
shift when tr
ansporting heavy objects; this
may affect vehicle handling and lead to an ac-
cident. Therefore, it is essential to adjust
your speed and driving style accordingly, to
avoid accidents.
● Never exceed the allowed axle weights or
allo
wed maximum weight. If said weights are
exceeded, the driving characteristics of the
vehicle may change, leading to accidents, in-
juries and damage to the vehicle.
● Never leave your vehicle unattended, espe-
cia
lly when the rear lid is open. Children
could climb into the luggage compartment,
closing the door behind them; they will be
trapped and run the risk of death.
● Never allow children to play in or around
the vehic
le. Close and lock all the doors and
the rear lid when you leave the vehicle. Be-
fore you lock the vehicle, make sure that
there are no adults or children in the vehicle. Note
● Air cir c

ulation in the vehicle helps reduce
fogging of the windows. Used air escapes
through ventilation slits in the side trim of
the luggage compartment. Ensure that the
ventilation slots are never covered.
● Straps for securing the load to the fasten-
ing ring
s are commercially available. Luggage compartment shelf
