Child safety
WARNING
● When travelling, children must be secured in the vehicle with a re-
straint system suitable for age, weight and size.
● Never install a child seat facing backwards on the front passenger
seat unless the front passenger airbag has been disabled. This could
cause fatal injuries to the child! However, if, in exceptional cases, it is
necessary to transport a child in the front passenger seat, the front pas-
senger airbag ⇒ page 44 must always be disabled and the seat adjusted
to its backmost highest position, where possible.
● Read and always observe information and warnings concerning the
use of child seats ⇒ page 47.

Central locking system
Description
The vehicle can be locked and unlocked via the central locking system.
There are several methods, depending on the vehicle equipment:
● key with remote control ⇒ page 91,
● lock on driver door (emergency opening ⇒ page 97) or
● interior central locking switch ⇒ page 93.
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 92.
Central locking (Auto Lock)
The Auto Lock function locks the doors and the rear lid when the vehicle ex-
ceeds a speed of about 15 km/h (10 mph).
The vehicle is unlocked again when the ignition key is removed. Alternative-
ly, the vehicle can also be unlocked via the central locking switch or by pull-
ing 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 92.
In the event of an accident in which the airbags inflate, the doors will be au-
tomatically unlocked to facilitate access and assistance. Anti-theft security system (Safelock)
1)
The following message is displayed on the instrument panel to remind the
driver that when the vehicle is closed from the outside, the anti-theft securi-
ty system is switched on.  Do not forget the Safelock. Please see Instruction
Manual. The vehicle cannot be opened from inside. This makes it more diffi-
cult for unauthorised persons to break into the vehicle ⇒ .
The anti-theft security system can be switched off each time the vehicle is
locked:
● Turn the key a second time to the lock position, in the door lock, for the
next two seconds . If necessary, remove the protective cover on the driver
door handle ⇒ page 97. or
● Press 
on the remote control key for a second time
for the following 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 approximately 30 seconds and, lastly continues flashing
slowly.
Anti-theft alarm system*
If the anti-theft alarm system senses interference 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 ig-
nition within 15 seconds. Otherwise the alarm will be triggered. On some
export versions, the alarm is triggered immediately when you open a door. 

The availability of this function depends on the vehicle equipment.

safety reasons, e.g. when stopped at traffic lights).
● The LED in the central locking switch lights up when all the doors are
closed and locked.
● You can open the doors individually from the inside by pulling the inside
door handle.
● In the event of an accident in which the airbags inflate, doors locked
from the inside will be automatically unlocked to facilitate access and assis-
tance.

ed off and automatically locks all the vehicle doors when the button 
is
pressed.
● The central locking switch does not operate if the vehicle is locked
from the outside and the anti-theft security system is switched on.
● Locked doors could delay assistance in an emergency, potentially
putting lives at risk. Do not leave anyone (especially children) in the vehi-
cle.
Note
The doors and the rear lid are locked automatically when the vehicle rea-
ches a speed of about 15 km/h (10 mph) (Auto Lock) ⇒  page 86. You can
unlock the vehicle again using button 
on the central locking switch.

ing switch The seat cushions can be heated electrically when the ignition is switched
on. The backrest is also heated in some versions.
The seat heating should not be engaged in any of the following conditions:
●
The seat is unoccupied.
● The seat has a covering.
● There is a child seat installed in the seat.
● The seat cushion is wet or damp.
● The indoor or outdoor temperature is greater than 25 °C (77 °F).
FunctionUsing seat heatingTo switch sys-
tem on:Press the button  or . Seat heating is switched on fully.
Adjusting the
heating out-
put:Press the button  or  repeatedly until the desired inten-
sity level is reached.
To switch sys-
tem off:Press the button  or  until all warning lamps switch off.
WARNING
People who, because of medications, paralysis or chronic diseases (e.g.
diabetes) cannot perceive pain or temperature, or have a limited percep-
tion thereof, may suffer burns to the back, buttocks or legs when using
seat heating, an occurrence that may entail a very lengthy recovery peri-
od or from which it may not be possible to recover fully. Seek medical ad-
vice if you have doubts regarding your health.
● People with a limit pain and temperature threshold must never use
seat heating. 

Seats and storage
WARNING
● Please make sure that any items of clothing hanging from the coat
hooks do not obstruct your view to the rear.
● The coat hooks should only be used for lightweight clothing. Do not
leave any heavy or sharp objects in the pockets.
● Do not use clothes hangers to hang up the clothing, as this could in-
terfere with the function of the head-protection airbags.

Roof carrier
Note the following points if you intend to carry loads on the roof:
● In your car only certain roof carriers should be used. Roof carriers are the
basis of a complete roof carrier system. To transport luggage and sports
equipment, additional structures/transport systems are needed. We recom-
mend roof carriers and structures from the SEAT accessories programme.
● When mounting the roof carrier, be sure to mount only on the points al-
ready provided on the roof. The front and rear attachment points are only
visible when the doors are open.
● The maximum permissible roof load for your vehicle is 75 kg. The load
limit applies to the combined weight of the roof carrier, the structures, and
load itself. However, check the load permitted by the specific loading sys-
tem being used. Permissible axle weight and permissible total weight for
your vehicle ⇒ page 267.
WARNING
● Take note of the mounting instructions for the roof carrier system. If
the carrier system and the roof load are not properly secured, items of
luggage could fall from the vehicle and cause an accident.
● When you use a roof carrier system the style of driving changes due
to a shift of emphasis and the larger surface area exposed to wind drag,
which could cause an accident. Therefore, it is essential to adjust your
speed and driving style accordingly, to avoid accidents.
CAUTION
Check that when the rear lid is open, it does not touch loads carried on the
roof. When a roof carrier is fitted, DO NOT open the panoramic roof*.
For the sake of the environment
Greater aerodynamic drag increases fuel consumption. For this reason you
should always take off the roof carrier when it is not in use. 

Lane Assist system* Introduction
Additional information and warnings:
● SEAT information system ⇒  page 73
● Accessories, parts replacement, repairs and modifications ⇒ page 230
WARNING
The intelligent technology in the Lane Assist system cannot change the
limits imposed by the laws of physics and by the very nature of the sys-
tem. Careless or uncontrolled use of the Lane Assist system may cause
accidents and injury. The system is not a replacement for driver aware-
ness.
● Always adapt your speed and the distance to the vehicles ahead in
line with visibility, weather conditions, the condition of the road and the
traffic situation.
● Always keep your hands on the steering wheel so it can be turned at
any time.
● The Lane Assist system does not detect all road markings. The road
surfaces, road structures or objects in poor condition can be incorrectly
detected as road markings under certain circumstances by the Lane As-
sist system. In such situations, switch the Lane Assist system off imme-
diately.
● Please observe the indications on the instrument panel and act as is
necessary.
● Always pay attention to the vehicle's surroundings.
● When the area of vision of the camera becomes dirty, covered or is
damaged, the Lane Assist system function can be affected.
CAUTION
In order to avoid influencing the operation of the system, the following
points must be taken into account:
● Regularly clean the area of vision of the camera and keep it in a clean
state, without snow or ice.
● Do not cover the area of vision of the camera.
● Check that the area of vision of the windscreen camera is not damaged. 
