 page 10
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 10) 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 (9 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 126.
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 123. 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. 128 or ››› Fig. 129 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

ock it if necessary. Unlocking/Locking by remote control

sed.
Automatically disabling sensors
If the vehicle is not locked or unlocked for a
long period of time, the proximity sensors on
the passenger doors are automatically disa-
bled.
If one of the sensor surfaces on the door han-
dles is often activated in a unusual manner
with the vehicle locked (e.g. by the branches
of a bush rubbing against it), all proximity sensors are disabled for a certain period of
time.
Sensors

will again be enabled:

● 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 87.
● 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.

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 141.
● If there is no valid key inside the vehicle or
the syst
em 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 sen sor

s are very dirty, e.g. have a lay-
er of salt, how the sensors on the door han-
dles operate may be affected. In this case,
clean the vehicle.
● If the vehicle is equipped with an automatic

strument
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-

mately

30 seconds and, lastly continues
flashing slowly.
