Operation
one of the handles permanently activates, all
windo
w
s 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 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.
● 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 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
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-
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-
sons to break into the vehicle ››› in De-
s c
ription on p

age 116.
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
necessary, remove the protective cover on
the driver door handle ›››
 page 10 or else
● Press  on the remote control key for a
sec ond time
w

ithin 2 seconds.
The flashing frequency of the diode in the
door sill immediately confirms the process.
Initially, the diode flashes in a fast sequence for a brief period, then it stops for approxi-
mately

30 seconds and, lastly continues
flashing slowly.

Operation
●
For the r e
ar seat belts to offer the necessa-
ry protection all the parts of the rear backrest
must be properly engaged. This is particular-
ly important in the case of the centre rear
seat. If someone is seated in a seat whose
backrest is not properly engaged they will fly
forward, along with the backrest, during an
accident or a sudden driving or braking ma-
noeuvre.
● A red signal on the button 2 warns that
the bac k

rest is not engaged. Always check
that the red marking is not visible when the
backrest is in the upright position.
● When the rear seat backrest is lowered or is
not properly
engaged nobody else can travel
in the corresponding seats (not even a child). CAUTION
Serious damage can be caused to the vehicle
and other ob j

ects if the rear seat backrest is
lowered or lifted without due care and atten-
tion.
● Before lowering the rear seat backrest, al-
way
s adjust the front seats so that neither
the head restraints nor the cushions of the
rear backrest can hit them. Transport and practical

table on page 2
All luggage and other loose objects must be
safely 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 157. 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.
● Use suitable straps to secure heavy ob-
jects.
● D

uring sudden manoeuvres or accidents,
loose ob
jects can be thrown forward, injuring vehicle occupants or passers-by. This in-
cr
e

ased 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
rear lid when you leave the vehicle. Before
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. ●
Strap s

for securing the load to the fasten-
ing rings are commercially available. Luggage compartment cover
