Driver assistance systems
and serious injury to the driver and passen-
gers.
●
Adjust your speed and driving style to visi-
bility, road, traffic and weather conditions.
Even though the brake assist systems, ABS,
BAS, EDL, ASR and ESC* provide more securi-
ty, do not take unnecessary risks while driv-
ing.
● Brake assist systems can not overcome the
laws of physics. Even with ESC* and other
systems, slippery and wet roads will always
be dangerous.
● Driving to quickly on wet ground can result
in the wheels losing contact with the ground
in an effect known as “aquaplaning”. Without
adherence, it is impossible to brake, steer or
control the vehicle.
● Brake assist systems cannot avoid acci-
dents if, for example, the driver does not re-
spect safety distances or drives to quickly in
difficult conditions.
● Even though brake assist systems are ex-
tremely effective and help control the vehicle
in difficult situations, remember that the ve-
hicle stability depends on tyre grip.
● When accelerating on a slippery surface,
for example on ice or snow, press the acceler-
ator carefully. The wheels can still slip even
with brake assist systems resulting in loss of
vehicle control. WARNING
The effectiveness of the ESC* can be consid-
erably reduced if other components and sys-
tems affecting driving dynamics are not main-
tained or are not functioning correctly. This
includes, among others, brakes, tyres and
other systems already mentioned.
● Remember that changing and fitting other
components to the vehicle can affect opera-
tion of the ABS, BAS, ASR TC, EDL and ESC*.
● Changes to the vehicle suspension or using
unapproved wheel/tyre combinations can af-
fect operation of the ABS, BAS, ASR, TC, EDL
and ESC* and their effectiveness.
● Likewise, the effectiveness of ESC* de-
pends on the use of suitable tyres
››› page 158. Note
● To ensure that the ESC*, ASR and TC work
properly, all four wheels must be fitted with
identical tyres. Any differences in the rolling
radius of the tyres can cause the system to
reduce engine power when this is not de-
sired.
● If a malfunction should occur in the ABS,
the ESC*, ASR, TC and EDL will also be affec-
ted.
● Noises may be heard while any of the
above systems are operating. Parking sensor system*
Introduction The parking sensor system assists the driver
when parking. If the rear of the vehicle is ap-
proaching an obstacle, an intermittent audi-
ble warning is emitted. The shorter the dis-
tance, the shorter the intervals between
tones. If the vehicle is too close to the obsta-
cle, the audible warning becomes constant.
If you continue to approach an obstacle when
the sound is continuous, this means the sys-
tem can no longer measure the distance.
Sensors situated on the rear bumper transmit
and receive ultrasound. Using the ultrasound
signal (transmission, reflection from the ob-
stacles and reception), this system continu-
ously calculates the distance between the
bumper and the obstacle.
WARNING
The parking distance warning system cannot
replace the driver's assessment of the situa-
tion.
● The sensors have blind spots in which ob-
stacles and people are not registered.
● Always observe the area around the vehi-
cle, as the sensors do not always detect
small children, animals or objects. » 105Technical specifications

Accessories, replacement of
parts and modifications Introduction WARNING
The use of spare parts and accessories, or in-
correctly performed modifications or repairs
may result in damage to the vehicle, acci-
dents and serious injury.
● SEAT strongly recommends you to only use
SEAT approved accessories and SEAT ®
origi-
nal spare parts. These parts and accessories
have been specially tested by SEAT for suita-
bility, reliability and safety.
● Have any repairs or modifications carried
out at a specialised workshop. These work-
shops have the necessary tools, diagnostics
equipment, repair information and qualified
personnel.
● Only mount parts with the same specifica-
tions as the parts fitted at factory.
● Never mount, fasten or fit objects such as
drink holders or telephone cradles over the
covers of the airbag modules or within their
deployment zones. ●
Only use wheels and tyre combinations
which have been approved by SEAT for your
vehicle type. Accessories and spare parts
SEAT recommends you consult an Official
Service before purchasing accessories and
spare parts or consumables. For example,
when fitting accessories at a later date, or
when replacing a component. A SEAT Official
Service will advise you as to the legal require-
ments and manufacturer's recommendations
regarding accessories, spare parts and other
components.
SEAT recommend you use only approved
SEAT accessories
and
genuine SEAT spare
p
arts ®
. These parts and accessories have
been specially tested by SEAT for suitability,
reliability and safety. In addition, SEAT tech-
nical services will guarantee that assembly is
performed professionally.
Although we continually monitor the market,
SEAT cannot guarantee that products not ap-
proved by SEAT are reliable, safe or suitable
for the vehicle. Therefore, SEAT cannot accept
liability, even in those cases authorised by
an officially recognised technical inspection
office or other official body.
Any retro-fitted equipment which has a direct
effect

on vehicle control must be approved by SEAT for use in your vehicle and bear the
e
mark (the European Union's authorisation
symbol). This includes cruise control systems
or electronically controlled suspension.
If any additional electrical devices are fitted
which do not serve to control the vehicle it-
self, these must bear the  mark (European
Union manuf

acturer conformity declaration).
This includes refrigerator boxes, laptops or
ventilator fans. WARNING
Unprofessional repairs or modifications to
the vehicle may affect the performance of the
airbags, and may cause operating faults or fa-
tal accidents.
● Never mount, fasten or fit objects such as
drink holders or telephone cradles over or
next to the covers of the airbag modules or
within their deployment zones.
● Objects placed over the airbag covers, or
within their deployment zones, could lead to
serious injury or loss of life if the airbags are
triggered. Fluids and consumables
All vehicle fluids and consumables
, such as
notched belts, tyres, coolant fluids, engine
oils, spark plugs and batteries are continual-

Advice
●
All repairs and modifications to the vehicle
should only be performed by a specialised
workshop. Repair and faults in the airbag system
When performing repairs and technical mod-
ifications, SEAT's directives must be ob-
served!
››› Modifications and repairs to the front bump-
er, doors, front seats, and repairs to the roof
or chassis should only be carried out in a
specialised workshop. These components
may contain parts or sensors belonging to
the airbag system.
If work is carried out on the airbag system or
parts have to be removed and fitted on the
system when performing other repair work,
parts of the airbag system may be damaged.
The consequence may be that, in the event of
an accident, the airbag inflates incorrectly or
does not inflate at all.
So that the effectiveness of the airbag is not
reduced and that removed parts do not cause
any injuries or environmental pollution, regu-
lations must be observed. These require-
ments are known to specialised workshops.
Modifications to the vehicle suspension may
affect the operation of the airbag system in
the event of collision. For example, if wheel
and tyre combinations not approved by SEAT are used, or if the vehicle height is lowered,
the suspension is stiffened or the suspension
springs, telescopic arms, dampers, etc., are
modified, the results received by the airbag
sensors and sent to the control unit may not
be accurate. For example, some modifica-
tions to the suspension could increase the
force measured by the sensors and result in
the triggering of the airbag systems in colli-
sions. Under normal conditions, the meas-
ured values would be lower and the airbag
would not have been triggered. Other modifi-
cations may reduce the forces measured by
the sensors and prevent the airbags from be-
ing triggered when they should.
WARNING
Repairs or modifications which are not per-
formed correctly may result in damage or er-
rors in the vehicle operation, affecting the ef-
fectiveness of the airbag systems. This could
result in serious or fatal accidents.
● All repairs and modifications to the vehicle
should only be performed by a specialised
workshop.
● Airbag modules must never be repaired: if
damaged, they must be replaced.
● Never fit recycled or reused airbag compo-
nents in your vehicle. WARNING
Modifications to the vehicle suspension, in-
cluding the use of unauthorised wheel and tyre combinations, may affect the perform-
ance of the airbags and increase the risk of
serious or fatal injury in the event of acci-
dent.
●
Never fit suspension components which are
not identical to the original parts in the vehi-
cle.
● Never use wheel and tyre combinations not
approved by SEAT. Retro-fitting of two-way radios
An exterior aerial is required for the use of
two-way radios in the vehicle.
The retro-fitting of electrical or electronic ap-
pliances in the vehicle is subject to their ap-
proval for use in your vehicle. Under certain
circumstances, this could mean that your ve-
hicle registration documents are no longer
valid.
SEAT has approved your vehicle for use with
two-way radios providing the following condi-
tions are observed:
● The exterior aerial must be mounted pro-
fessionally.
● The maximum transmitting power is 10
watts.
The optimal reach of the equipment is only
achieved with an external aerial.

Advice
Foreign bodies in the tyre
● Do not remove foreign bodies if they have
penetrated through the tyre wall!
● You should obtain professional assistance
immediately.
Wear of tyres
The wear of tyres depends on a number of
factors, for example:
● Driving style.
● Unbalanced wheels.
● Running gear settings.
Driving style : Driving round bends quickly or
sudden acceleration or braking speed accel-
erates tyre wear. When the driving style is
normal, if the tyres wear too quickly, have the
running gear settings checked at a special-
ised workshop.
Wheel run-out : The wheels on new vehicles
ar e b
alanced. However, certain circumstan-
ces may lead to imbalance (run-out), which is
detected as vibrations in the steering wheel.
Run-out leads to wear of the steering and
suspension. In the event of run out, the
wheels should be balanced again. When a
new wheel is fitted, it should be balanced
again.
Running gear settings : an incorrectly posi-
tioned running gear increases the wear of
tyres and affects your safety while driving. If tyres wear too quickly, have the wheel align-
ment checked at a specialised workshop. WARNING
If you notice unusual vibration or the car pulls
to one side while driving, this may indicate
that one of the tyres is damaged.
● Reduce speed immediately and stop, while
observing the highway code.
● Check the wheels and tyres for damage.
● Never carry on driving on worn tyres or
wheels. Request qualified assistance immedi-
ately.
● If there is no visible exterior damage, drive
slowly and carefully to the nearest special-
ised workshop and have the vehicle checked. Tyre monitoring system* 
Fig. 117
Centre console: tyre monitor system
button The tyre control lamp compares wheel revolu-
tions and with it, the wheel diameter of each
wheel using the ESC. If the diameter of a
wheel changes, the tyre control lamp

lights up. The wheel diameter changes when:
● Tyre pressure is insufficient.
● The tyre structure is damaged.
● The vehicle is unbalanced because of a
load.
● The wheels of one axle are under more
pressure (for example, driving with a trailer or
on steep slopes).
● The vehicle is fitted with snow chains.
● The temporary spare wheel is fitted.
● The wheel on one axle is changed.
Tyre pressure adjustment
On adjusting tyre pressure or changing one
or more wheels, the ››› Fig. 117 button must
be k ept
pressed down, with the ignition on,
until an acoustic signal is heard.
If the wheels are under excessive load (for ex-
ample, driving with a trailer or heavy load),
the tyre pressure must be increased to the
recommended value for a full load (see the
sticker on the inside of the fuel flap). If the
tyre monitor system button is pressed down,
the new tyre pressures are confirmed.
