Loading luggage compartment
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 ⇒ 
.

● Light ⇒ page 84
● Transporting ⇒ page 97
● Wheels and tyres ⇒ page 210
WARNING
When the vehicle is not in use or being watched, always lock the doors
and the rear lid to reduce the risk of serious injury or death.
● Do not leave children unwatched, especially when the rear lid is open.
Children could climb into the luggage compartment, close the rear lid
from inside and be unable to escape themselves. This could lead to seri-
ous injury or death.
● Never allow children to play in or around the vehicle.
● Never transport people in the luggage compartment.
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.
● Always secure objects with suitable rope or straps so that they can-
not enter the deployment areas around the frontal or side airbags in case
of sudden braking or an accident.
● While driving, always keep object compartments closed.
● Do not place hard, heavy or sharp objects inside the interior, in open
storage compartments, the rear shelf or on the dash panel.
● Remove hard, heavy and sharp objects from clothes and pockets in-
side the vehicle and store securely.
WARNING
The transport of heavy object changes vehicle handling and increases
braking distance. Heavy loads that have not been stored or secured cor-
rectly could cause loss of control and result in serious injury.
● The vehicle handling changes when transporting heavy objects due
to a change in the centre of gravity.
● Distribute the load as uniformly and as low down on the vehicle as
possible.
● Store heavy objects in the luggage compartment as far from the rear
axle as possible.
CAUTION
Hard objects on the rear shelf could chafe against the wires of the heating
element in the heated rear window and cause damage. 

● Keep hands, fingers, feet and other limbs away from the range of the
rear seat backrests when folding and lifting them.
● All backrests must engage correctly for the seat belts on the rear
seats to work properly. When the backrest of an occupied seat is not cor-
rectly locked in place, the passenger can be thrust forward with the rear
seat backrest in case of sudden braking, sudden manoeuvres or an acci-
dent.
● A red signal on the button B
warns that the backrest is not engaged.
Always check that the red marking is not visible when the backrest of the
rear seat is in the upright position.
● No seat must be occupied if the backrest of the rear seat is folded or
not correctly engaged.
CAUTION
Before folding the backrest of the rear seat, adjust the front seats so that
the head restraint or backrest do not hit them when it is folded. If necessary,
remove the head restraints ⇒ page 48 and store them safely. 

WARNING
If unsuitable or damaged belts or retaining straps are used, they could
break in the event of braking or an accident. Objects could then be
launched across the passenger compartment and cause serious or fatal
injuries.
● It is important to always use belts or retaining straps that are suita-
ble and in a good condition.
● Belts and retaining straps should be securely fastened to the fasten-
ing rings.

suddenly and modify the handling of the vehicle.
● Small and light objects must also be secured.
● The maximum tensile load of the fastening ring for securing objects
should never be exceeded.
● A child seat should never be secured with the fastening rings.
Note
● The maximum tensile load that the fastening rings can support is 3.5
kN.
● Belts and securing systems for the appropriate load can be obtained
from specialised dealerships. SEAT recommends visiting a SEAT dealership
for this. Retaining hooks

Roof carrier system
Introduction
The vehicle roof has been designed to optimise aerodynamics. For this rea-
son, conventional roof carrier systems cannot be secured to the water
drains.
Given that the water drains have been incorporated into the roof for aerody-
namic reasons, only the SEAT approved basic supports and roof carrier sys-
tems can be used.
When the roof carrier system should be removed:
● When it is not being used.
● When the vehicle is being washed in a car wash.
● When the vehicle height exceeds the maximum height, for example, in a
garage.
Additional information and warnings:
● Light ⇒ page 84
● Transporting ⇒  page 97
● Ecological driving ⇒ page 144
● Wheels and tyres ⇒ page 210
● Accessories, parts replacement, repairs and modifications ⇒ page 222
WARNING
The risk of an accident is increased by transporting heavy or bulky loads
on the roof, which affects the vehicle's handling by shifting the centre of
gravity and increasing susceptibility to cross winds.
● Always secure loads correctly with suitable and undamaged attach-
ment rope or straps.
● Large, heavy, wide and flat loads negatively affect the vehicle aerody-
namics, centre of gravity and handling.
● Avoid brusque manoeuvres and sudden braking.
● Adjust your speed and driving style to visibility, road, traffic and
weather conditions.
CAUTION
● Always remove the roof carrier system from the roof before entering a car
wash.
● The height of your vehicle is changed by the installation of the roof carri-
er and the load secured on it. Compare the vehicle height with the passage
height, for example in underground car parks or entering garage doors.
● The roof antenna and the range of the rear lid should not be affected by
the roof carrier system and the load being transported.
● Take extra care not to let the rear lid strike the roof load when opening.
For the sake of the environment
The vehicle uses more fuel when the roof carrier system is fitted. 

points for the basic sup-
port and the roof carrier
system
The mounts are the basis of a complete roof carrier system. Special fixtures
must then be added in order to safely transport luggage, bicycles, skis, surf
boards or boats on the roof. The suitable accessories can be acquired at
SEAT dealerships.
Securing the base supports and roof carrier system
The roof carrier system must always be installed exactly according to the in-
structions provided.
The front attachment opening can be found in the lower part of the sides of
the roof and are fixed with plastic bolts ⇒ Fig. 70 (left magnified image).
The openings can only be seen with the door open. The markings for attach-
ment in the lower part are found in the upper part of the rear side windows
⇒ Fig. 70 (right magnified image).
The base support should only be fitted to the points indicated in the dia-
gram.
WARNING
If the base supports and the roof carrier system are incorrectly fitted or
used in an unsuitable manner, the entire system could break free causing
accident and injury.
● Always take the manufacturer assembly instructions into account.
● Only use base supports and roof carrier systems that are not dam-
aged and are correctly fitted.
● The base support should only be fitted to the points indicated in the
diagram ⇒ Fig. 70.
● Secure the base supports and roof carrier system correctly.
● Check the screw fittings and attachments before driving and after a
short distance. During each long journey, check the attachments during
every break.
● Always fit the roof carrier system correctly for wheels, skis and surf-
boards, etc.
● Never change or repair the basic supports or roof carrier system.
Note
Read and take into account the instructions included with the roof carrier
system fitted and keep them in the vehicle. 
Loading the roof carrier system
Loads can only be correctly secured when the roof carrier system is correctly
fitted ⇒ .
Maximum authorised roof load
The maximum authorised roof load is 50 kg. The roof load includes the
weight of the base support, the roof carrier system and the load being
transported ⇒

106Transporting
Always check the weight of the base support, the roof carrier system and
the weight of the load to be transported and, if necessary, weigh them. Nev-
er exceed the maximum authorised roof load.
If you are using a roof carrier with a lower weight rating, you cannot trans-
port the maximum roof load. Do not exceed the maximum weight limit for
the roof carrier given in the fitting instructions.
Distributing a load
Uniformly distribute loads and secure them correctly ⇒ 
.
Check attachments
After fitting the base supports and the roof carrier system, always check the
attachments after a short trip or at regular intervals.
WARNING
Exceeding the maximum authorised roof load can result in accidents
and/or vehicle damage.
● Always respect the maximum authorised weight for the roof, the max-
imum authorised weight on the axles and the total maximum authorised
weight of the vehicle.
● Never exceed the capacity of the roof carrier system even if this is
less than the maximum authorised roof load.
● Secure heavy objects towards the front and distribute the load even-
ly.
WARNING
Loose and incorrectly secured loads can fall from the roof carrier system
causing accidents and injury.
● Always use suitable ropes and straps in good condition.
● Always secure loads correctly.

Introduction
Storage compartments must only be used to store light or small objects.
Additional information and warnings:
● Care and cleaning of the vehicle interior ⇒ page 205
● ⇒ Booklet Radio system
WARNING
In the event of sudden braking movements or turns, loose objects may be
thrown around the vehicle interior. This could cause serious injuries to
passengers and cause the driver to lose control of the vehicle.
● Do not transport animals or place hard, heavy or sharp objects in the
interior of the vehicle in: open storage compartments, dash panel, stor-
age tray, items of clothing or bags.
● While driving, always keep object compartments closed.
WARNING
Objects falling into the driver's footwell could prevent use of the pedals.
This could lead the driver to lose control of the vehicle, increasing the
risk of a serious accident.
● Make sure the pedals can be used at all times, with no objects rolling
underneath them.
● The floor mat should always be secured to the floor.
WARNING (Continued)
● Never place other mats or rugs on top of the original mat supplied by
the factory.
● Make sure that no objects can fall into the driver's footwell while the
vehicle is in motion.
CAUTION
● Objects on the shelf could chafe against the wires of the heating ele-
ment in the heated rear window and cause damage.
● Do not keep temperature-sensitive objects, food or medicines inside the
vehicle. Heat and cold could damage them or render them useless.
● Light-transparent objects placed inside the vehicle, such as lenses,
magnifying glasses or transparent suction caps on the windows, could con-
centrate the sun's rays and cause damage to the vehicle.
Note
The ventilating slits between the heated rear window and the rear shelf
must not be covered so that used air can escape from the vehicle. 
