Use of the child seat on the front passenger seat
Transporting children on the front passenger seat is not permitted in all
countries. Furthermore, not all child seats are approved for use on the front
passenger seat. Your SEAT dealership has an updated list of all approved
child seats. Only used child seats that are approved for each vehicle.
The frontal airbag on the front passenger side is highly dangerous for a
child. The front passenger seat is life-threatening to a child if he or she is
transported in a rear-facing child seat.
If a rear-facing child seat is secured to the front passenger seat, an inflating
airbag can strike it with such great force that severe or fatal injuries may re-
sult ⇒ 
. Therefore, rear-facing child seats must never be used on the front
passenger seat when the front passenger airbag is enabled.
Only use a rear-facing child seat on the front passenger seat if the front pas-
senger airbag is disabled. When it is disabled, the yellow PASSENGER
AIR BAG   ⇒ page 67 control lamp on the dash panel will be lit. If you
cannot disable the front passenger airbag and it remains enabled, it is for-
bidden to transport children on the front passenger seat ⇒ 
.

Things to note if using a child seat on the front passenger seat:
●
The front passenger front airbag must be disabled  when using a rear-
facing child seat ⇒ page 67.
● The backrest of the front passenger seat must be upright.
● Move the front passenger seat as far back as possible.
● The backrest of the front passenger seat must be upright.
Suitable child seats
The child seat must be authorised by the manufacturer especially for use on
a front passenger seat with a frontal or side airbag.
Universal seats for children can be fitted in the front passenger seat, in
groups 0, 0+, 1, 2 or 3 according to the ECE-R 44 regulation.
WARNING
If a child seat is mounted on the front passenger seat, the risk of the
child sustaining severe or fatal injuries in the event of an accident increa-
ses. Rear-facing child seats must never be mounted on the front passen-
ger seat when the front passenger airbag is enabled. This is life-threaten-
ing to the child should the frontal airbag deploy, as the child seat would
be struck by the inflated airbag and thrown against the backrest.
WARNING
If, in exceptional circumstances, a child must be transported in a rear-fac-
ing child seat on the front passenger seat, strictly observe the following:
● Always disable the front passenger airbag and leave it disabled.
● The child seat must be approved by the manufacturer for use on a
front passenger seat with frontal and side airbag.
● Follow the installation instructions of the child seat manufacturer and
observe the warnings. 

WARNING (Continued)
● Move the front passenger seat as far back as possible and adjust it to
its highest position to keep as far away as possible from the frontal air-
bag.
● Move the backrest to the upright position.
● Children must always be protected with an approved child restraint
system suited to their height and weight.

Use of the child seat on the rear seat
If a child seat is mounted on the rear seat, adapt the position of the front
passenger seat so that the child has enough space. Therefore, adapt the
front passenger seat to the size of the child seat and the height of the child.
Ensure the passenger is in the correct position  ⇒ page 48.
Suitable child seats
The manufacturer must authorise the child seat for use in the rear seats with
side airbags.
Universal seats for children can be fitted in the passenger seat, in groups 0,
0+, 1, 2 or 3 according to the ECE-R 44 regulation.
The rear seats are suitable for child seats with the ISOFIX system specially
designed for this type of vehicle in accordance with regulation ECE-R 44.
ISOFIX child seats approved for rear seats
ISOFIX child seats are divided into certified categories “universal”, “semi-
universal” or “specific categories for the vehicle”.
● If the ISOFIX child seat is certified “universal”, it must be supported by
the lower anchor points and the Top Tether retaining strap.
● If the ISOFIX child seat is certified “semi-universal” or “specific catego-
ries for the vehicle”, check that the child seat is certified for the vehicle be-
fore employing it. The child seat manufacturer supplies, in addition to the ISOFIX child seat, a list of vehicles for which the corresponding ISOFIX child
seat has been certified. If necessary, contact the child seat manufacturer for
an updated list of vehicles.

Child seats with rigid mounting
For the installation of a child seat with rigid mounting auxiliary introduction
elements can be used. Using auxiliary introduction elements facilitates in-
stallation and protects upholstery. Auxiliary introduction elements form part
of the supply volume of the child seat or can be acquired at a SEAT dealer-
ship. If necessary, auxiliary introduction elements are inserted in both an-
chor points of the vehicle ⇒ 
.
● Observe the manufacturer's instructions when installing and removing
the child seat ⇒

Driving tips Introduction
Always transport heavy loads in the luggage compartment and place the
seat backs in a vertical position. Never overload the vehicle. Both the carry-
ing capacity as well as the distribution of the load in the vehicle have ef-
fects on the driving behaviour and braking ability ⇒ 
.
Additional information and warnings:
● Rear lid ⇒ page 40
● To lower the front passenger seat backrest ⇒ page 55
● Light ⇒ page 84

● Wheels and tyres ⇒ page 210
WARNING
Unsecured or incorrectly secured objects can cause serious injury in case
of a sudden manoeuvring or breaking or in case of an accident. This is es-
pecially true when objects are struck by a detonating airbag and fired
through the vehicle interior. To reduce the risks, please note the follow-
ing:
● Secure all objects in the vehicle. Always keep equipment and heavy
objects in the luggage compartment.
WARNING (Continued)
● Always secure objects with suitable rope or slings so that they cannot
enter the deployment areas around the frontal or side airbags in case of
sudden braking or an accident.
● Always ensure that objects inside the vehicle cannot move into the
deployment area of the bags while driving.
● While driving, always keep object compartments closed.
● Remove all objects from the front passenger seat when this is fol-
lowed down. When the seat backrest is folded down, it presses on small
and light objects and these are detected by the weight sensor on the
seat; this sends false information to the airbag control unit.
● While the backrest of the front passenger seat is folded, the frontal
airbag must remain disconnected and the PASSENGER AIRBAG OFF 
light on.
● Objects secured in the vehicle should never be placed in such a way
as to make passengers sit in an incorrect position.
● If secured objects occupy a seat then this should not be occupied or
used by anybody.
WARNING
The driving behaviour and braking ability change when transporting
heavy and large objects.
● Adjust your speed and driving style to visibility, road, traffic and
weather conditions.
● Accelerate gently and carefully.
● Avoid sudden braking and manoeuvres.
● Brake early.

Transporting a load
Secure all objects in the vehicle
●Distribute the load throughout the vehicle and on the roof as uniformly
as possible.
● Transport heavy objects as far forward as possible in the luggage com-
partment and lock the seat backs in the vertical position.
● Check the headlight adjustment ⇒ page 84.
● Use the suitable tyre pressure according to the load being transported.
Read the tire pressure information label ⇒ page 210.
CAUTION
Objects on the shelf could chafe against the wires of the heating element in
the heated rear window and cause damage.
Note
Please refer to the notes on loading the roof carrier ⇒ page 104. 
Driving with the rear lid open
Driving with the rear lid open creates an additional risk. Secure all objects
and secure the rear lid correctly and take all measures possible to reduce
toxic gases from entering the vehicle.
WARNING
Driving with the rear lid unlocked or open could cause serious injuries.
● Always drive with the rear lid closed.
WARNING (Continued)
● Secure all objects in the vehicle. Loose items could fall out of the ve-
hicle and injure other road users or damage other vehicles.
● Drive particularly carefully and think ahead.
● Avoid sudden manoeuvres and braking given that this could cause an
uncontrolled movement of the open rear lid.
● When transporting objects that protrude out of the luggage compart-
ment, indicate them suitably. Observe legal requirements.
● If objects must project out of the luggage compartment, the rear lid
must never be used to “secure” or “attach” objects.
● If a baggage rack is fitted on the rear lid, it should be removed before
travelling with the rear lid open.
WARNING
Toxic gases may enter the vehicle interior when the rear lid is open. This
could cause loss of consciousness, carbon monoxide poisoning, serious
injury and accidents.
● To avoid toxic gases entering the vehicle always drive with the rear lid
closed.
● In exceptional circumstances, if you must drive with the rear lid open,
observe the following to reduce the entry of toxic gases inside the vehi-
cle:
–Close all windows.
– Disable air recirculation mode.
– Open all of the air outlets on the instrument panel.
– Switch on the blower to maximum.
CAUTION
An open rear lid changes the length and height of the vehicle. 

● Secure all objects ⇒ page 98.
● Accelerate gently and carefully.
● Avoid sudden braking and manoeuvres.
● Brake early.
● If necessary, read the instructions for driving with a roof carrier system
⇒ page 104.
WARNING
A sliding load could considerably affect the stability and safety of the ve-
hicle resulting in an accident with serious consequences.
● Secure loads correctly so they do not move.
● When transporting heavy objects, use suitable ropes or straps.
● Lock the seat backs in vertical position.
