WARNING (Continued)
● Changes to the vehicle suspension or using unapproved wheel/tyre
combinations can affect operation of the ABS, BAS, ASL EDL and ESC and
their effectiveness.
● Likewise, the effectiveness of ESC depends on the use of suitable
tyres ⇒ page 297.
Note
● To ensure that the ESC and ASR 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 desired.
● If a malfunction should occur in the ABS, the ESC, EDL and ASR will also
be out of action.
● Noises may be heard while any of the above systems are operating. 
Turning on and off the ASR
Fig. 137 Detailed view of
the centre console: but-
ton used to switch ASR
on and off (vehicles with
ESC). The electronic stability control ESC consists of ABS, EDL and ASR and only
works when the engine is running.
The ASR can be switched off while the engine is running by pressing the
 OFF
⇒ fig. 137 button. The ASR (and similar) is only switched off when the
required traction is not obtained:
● When driving through deep snow or on loose ground (gravel...).
● When freeing a trapped vehicle.
Turn the ASR back on by pressing the button  OFF

Brake fluid

In the course of time, the brake fluid absorbs water from the ambient air. If
there is too much water contained in the brake fluid, the brake system could
be damaged. In addition, the boiling point of the brake fluid is significantly
lowered. When the brake fluid contains too much water and the brakes are
subject to considerable forces, bubbles of water vapour can form in the sys-
tem. These bubbles of water vapour can significantly reduce braking power, 

Introduction
WARNING
The use of spare parts and accessories, or incorrectly performed modifi-
cations or repairs may result in damage to the vehicle, accidents and se-
rious injury.
● SEAT strongly recommends you to only use SEAT approved accesso-
ries and SEAT ®
original spare parts. These parts and accessories have
been specially tested by SEAT for suitability, reliability and safety.
● Have any repairs or modifications carried out at a Technical Service.
Qualified workshops have the necessary tools, diagnostics equipment,
repair information and qualified personnel.
● Only mount parts with the same specifications 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 radius of ac-
tion.
● 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 acces-
sories and spare parts or consumables. For example, when fitting accesso- ries at a later date, or when replacing a component. A Technical Service will
advise you as to the legal requirements and manufacturer's recommenda-
tions regarding accessories, spare parts and other components.
SEAT recommend you use only approved
SEAT accessories and genuine
SEAT spare parts ®
. These parts and accessories have been specially tested
by SEAT for suitability, reliability and safety. In addition the Technical Serv-
ices will guarantee that the assembly is carried out professionally.
Although we continually monitor the market, SEAT cannot guarantee that
products not approved by SEAT are reliable, safe and suitable for the vehi-
cle. 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 the vehicle and/or
the way it is driven 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 components are fitted which do not serve to con-
trol the vehicle itself, these must bear the  mark (European Union manu-
facturer conformity declaration). This includes refrigerator boxes, laptops or
ventilator fans.
WARNING
Unprofessional repairs or modifications to the vehicle may affect the per-
formance of the airbags, resulting in operating faults or fatal accident.
● Never mount, fasten or fit objects such as drink holders or telephone
cradles over the covers of the airbag modules or within their radius of ac-
tion.
● Objects placed over the airbag covers, or within their radius of action,
could lead to serious injury or loss of life if the airbags are triggered.

Accessories, parts replacement and modifications
The vehicle owner should keep the documentation for the additional equip-
ment safely and hand it over to the scrap yard at the end of the vehicle's
service life. This ensures that any additional equipment mounted in end-of-
life vehicles is correctly disposed of with respect for the environment.
WARNING
Repairs or modifications which are not performed correctly may result in
damage or errors in the vehicle operation, affecting the efficiency of the
driver assist systems. This could result in serious accident.
● 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 modifications, SEAT's directives
must be observed! ⇒ 
Modifications and repairs to the front bumper, doors, front seats, and re-
pairs to the roof or chassis should only be carried out in a Technical Service.
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, regulations must
be observed. These requirements are known to qualified dealerships.
Modifications to the vehicle suspension may affect the operation of the air-
bag system in the event of collision. For example, if wheel and tyre combi-
nations 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 collisions. Under normal
conditions, the measured values would be lower and the airbag would not
have been triggered. Other modifications may reduce the forces measured
by the sensors and therefore the airbags are not triggered in situations
when they should have triggered.
WARNING
Repairs or modifications which are not performed correctly may result in
damage or errors in the vehicle operation, affecting the efficiency of the
airbag systems. This could result in serious or fatal accident.
● 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 re-
placed.
● Never fit recycled or reused airbag components in your vehicle.
WARNING
Modifications to the vehicle suspension, including the use of unauthor-
ised wheel and tyre combinations, may affect the performance of the air-
bags 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 origi-
nal parts mounted in the vehicle.
● Never use wheel and tyre combinations not approved by SEAT.
