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.

● 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. 

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.

Storage compartments
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. 

Do not allow floor mats or other objects to obstruct the free passage of the
pedals.
Floor mats should leave the pedal area vacant and unobstructed and be cor-
rectly secured in the footwell zone. In the event of failure of a brake circuit, the brake pedal must be pressed
harder than normal to brake the vehicle.
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.
● Always secure the mat in the footwell.
● Never place other mats or rugs on top of the original mat supplied by
the factory.
● Ensure that no objects can fall into the driver's footwell while the ve-
hicle is in motion.
CAUTION
The pedals must always have free and unobstructed passage to the floor.
For example, in case of a fault in the brake circuit, the brake pedal will need
to be pressed further to stop the vehicle. To press the brake pedal down fur-
ther will require more force than usual. 

140Starting, changing gears, parking
The ABS, BAS, ASR and EDL systems are incorporated into the ESC*. The
ESC* is always on 1)
.
Anti-lock brake system (ABS)
ABS can prevent the wheels from locking during braking until just before
the vehicle stops thus helping the driver to steer the vehicle and maintain
control. This means that, even during full braking, the risk of skidding is re-
duced:
● Press and hold the brake pedal fully. Do not remove your foot from the
brake pedal or reduce braking force!
● Do not “pump” the brake pedal, or reduce braking force!
● Maintain vehicle direction when braking fully with the brake pedal.
● When the brake pedal is released or when the brake force is reduced,
ABS is turned off.
ABS control can be observed by vibration of the brake pedal and noise. You
should never expect the ABS to reduce the braking distance under any cir-
cumstances. Braking distances will increase when driving on gravel, recent
snow or on icy and slippery ground.
Brake assist system (BAS)
The brake assist system may reduce the required braking distance. The
brake assist system boosts the braking force if you press the brake pedal
quickly in an emergency. As a result, the braking pressure increases rapidly,
the braking force is multiplied and the braking distance is reduced. This en-
ables the ABS to be activated more quickly and efficiently.
¡Do not lift your foot off the brake pedal! When the brake pedal is released
or when the brake force is reduced, braking assist automatically turns off
the brake servo. Traction control system (ASR) or Traction Control (TC)
In the event of wheelspin, the traction control system ASR or TC reduces the
engine torque to match the amount of grip available. The ASR or TC makes
some situations easier, for example, when starting, accelerating or going
uphill, even in unfavourable road conditions.
Electronic differential lock system (EDL)
EDL is available when driving in straight lines under normal conditions.
When the EDL detects wheelspin, it brakes the spinning wheel and directs
the power to the other driven wheel. To prevent the disc brake of the braked
wheel from overheating, the EDL cuts out automatically if subjected to ex-
cessive loads. The EDL will switch on again automatically when the brake
has cooled down.
WARNING
Driving at high speed on icy, slippery wet ground can result in loss of ve-
hicle control and serious injury to the driver and passengers.
● Adjust your speed and driving style to visibility, road, traffic and
weather conditions. Even though the braking assist systems, ABS, BAS,
EDL, ASR, TC and ESC*, provide more security, do not take unnecessary
risks while driving.
● Braking assist systems can not overcome the laws of physics. Even
with ESC* and other systems, slippery and wet roads will always be dan-
gerous.
● Driving to quickly on wet ground can result in the wheels losing con-
tact with the ground in an effect known as “aquaplaning”. Without ad-
herence, it is impossible to brake, steer or control the vehicle.
● Braking assist systems cannot avoid accidents if, for example, the
driver does not respect safety distances or drives to quickly in difficult
conditions. 
