Multi-collision brake
In an accident, the multi-collision brake can help the driver by braking to
avoid the risk of skidding during the accident, which could lead to further
collisions.
The multi-collision brake works for front, side or rear accidents, when the
airbag control unit records its activation level and the accident takes place
at a speed of over 10 km/h (6 mph). The EI ESC automatically brakes the
vehicle, as long as the accident has not damaged the ESC, the brake hy-
draulics or the on-board network.
The following actions control automatic braking during the accident:
● When the driver presses the accelerator. The automatic braking does not
take place.
● When the braking pressure through pressing the brake pedal is greater
than the system’s braking pressure. The vehicle will brake manually.
● Multi-collision braking will not be available if ESC is malfunctioning.
WARNING
● Nor can the ESC, ABS, ASR, EDL, electronic self-locking differential or
selective torque control systems exceed the limits imposed by the laws
of physics. Always bear this in mind, especially on wet or slippery roads.
If you notice the systems cutting in, you should reduce your speed imme-
diately to suit the road and traffic conditions. Do not be encouraged to
take risks by the presence of more safety systems. If you do, an accident
may occur.
● Please remember that the accident risk always increases if you drive
fast, especially in corners or on a slippery road, or if you follow too close
behind the vehicle in front of you. The ESC, ABS, brake assist, EDL, elec-
tronic self-locking and selective torque control systems cannot prevent
accidents: risk of accidents!
● Accelerate with caution on slippery surfaces (for example, icy or
snow-covered). Despite the control systems, the driven wheels could
spin, affecting the stability of the vehicle: risk of accident!
Note
● The ABS and ASR will only operate correctly if the four wheels have iden-
tical tyres. Any differences in the rolling radius of the tyres can cause the
system to reduce engine power when this is not desired.
● The regulating processes of the systems can make noises when they in-
tervene.
● If the warning lamp  lights up, or  alternatively, there could be a
fault ⇒ page 69. 
Switching on/off the ESC and ASR
The ESC is switched on automatically when the engine is
started. The ESC cannot be deactivated. ESC in "Sport" mode
Sport mode is activated through the Easy Connect system ⇒ page 79 menu.
The ability of the ESC to stabilise the vehicle is limited; the traction control
system (ASR) becomes disabled ⇒ 
.
The control lamp  will light up. For vehicles with a driver information sys-
tem*, the driver will be shown the electronic stability control (ESC) option:
sport. Warning! Limited stability .
In the following exceptional circumstances enabling the ESC Sport mode to
improve the traction of the wheels is tenable:
● when rocking the vehicle backwards and forwards to free it.
● Driving in deep snow or on loose surfaces.
Disable ESC Sport mode
Through the Easy Connect system ⇒ page 79. The warning lamp  will
switch off. For vehicles with a driver information system*, the driver will be
shown the electronic stability control (ESC) option: on .

Intelligent technology
Information recorded in the control units
Your vehicle is fitted at the factory with a series of electronic control units
responsible for the engine and gearbox management. In addition, the con-
trol units supervise the correct performance of the exhaust gas system and
the airbag systems.
Therefore, while the vehicle is being driven, these electronic control units
are continuously analysing the vehicle data. In the event of faults or devia-
tions from the theoretical values, only this data is stored. Generally, the in-
strument panel warning lamps indicate whether there are any malfunctions.
This data can only be read and analysed using special equipment.
The storing of the data allows specialised workshops to detect and repair
faults. Stored data may include:
● Important data about the engine and gearbox
● Speed
● Direction of travel
● Braking force
● Seat belt check
The vehicle control units never record conversations held by passengers in
the vehicle.
If the control unit records an accident with airbag activation, the system
may automatically send a signal. This will depend on the network operator.
Normally, transmission is only possible in areas with sufficient coverage.
Event Data Recorder
The vehicle is not fitted with an event data recorder.
An event data recorder temporarily stores the vehicle information. There-
fore, in the event of accident, it is possible to obtain detailed information
about how the accident occurred. For example, in vehicles with airbag sys-
tems, data relating to speed of impact, seat belt status, seat positions and airbag activation times may be stored. The volume of data depends on the
manufacturer.
Event data recorders can only be mounted with authorisation from the vehi-
cle owner and, in some countries, they are governed by local legislation.
Reprogramming control units
On the whole, all the data required for the component management is stor-
ed in the control units. The programming of certain convenience functions,
such as the turn signal convenience mode, individual door opening and dis-
play indications can be modified using special equipment at the workshop.
If the convenience functions are reprogrammed, the Instruction Manual in-
formation and descriptions will not coincide with the modified functions.
Therefore, SEAT recommends that any changes are recorded in the “Other
workshop notes section” of the Service Plan.
You can find out about possible reprogramming at your SEAT Official Serv-
ice.
Event recorder
In the footwell on the driver side you will find the diagnostics connection
socket for reading the event recorder. The event recorder stores operating
data and data on the status of the electronic control units. The events re-
corder should only be read and deleted by a SEAT Official Service or special-
ised workshop.
WARNING
The diagnostics connection socket must not be used for private purpo-
ses. Improper use can cause malfunctions: risk of accident!

Accessories, replacement parts and repairs
Always ask your dealer or specialist retailer for advice be-
fore purchasing accessories and replacement parts.
Your vehicle is designed to offer a high standard of active and passive safe-
ty. For this reason, we recommend that you ask a SEAT Official Service for
advice before fitting accessories or replacement parts. Your SEAT Official
Service has the latest information from the manufacturer and can recom-
mend accessories and replacement parts which are suitable for your re-
quirements. They can also answer any questions you might have regarding
official regulations.
We recommend you to use only SEAT accessories and Genuine SEAT parts ®
.
SEAT has tested these parts and accessories for suitability, reliability and
safety. SEAT Official Services have the necessary experience and facilities to
ensure that the parts are installed correctly and professionally.
Any retro-fitted equipment which has a direct effect on the vehicle and/or
the way it is driven (e.g. cruise control system or electronically-controlled
suspension) must be approved for use in your vehicle and bear the e mark
(the European Union's authorisation symbol).
If any additional electrical components are fitted which do not serve to con-
trol the vehicle itself (for instance a refrigerator box, laptop or ventilator fan,
etc.), these must bear the  mark (manufacturer conformity declaration in
the European Union).
WARNING
Accessories, for example telephone holders or cup holders, should never
be fitted on the covers, or within the working range of the airbags. Other-
wise, there is a danger of injury if the airbag is triggered in an accident.
 Technical modifications
Modifications must always be carried out according to our
specifications.
Unauthorised modifications to the electronic components, software, wiring
or data transfer in the vehicle may cause malfunctioning. Due to the way the
electronic components are linked together in networks, other indirect sys-
tems may be affected by the faults. This can seriously impair safety, lead to
excessive wear of components, and also invalidate your vehicle registration
documents.
You will appreciate that your SEAT dealership cannot be held liable for any
damage caused by modifications and/or work performed incorrectly.
We recommend that all work should be performed by a SEAT Official Service
using Genuine SEAT parts
®
.
WARNING
Incorrectly performed modifications or other work on your vehicle can
lead to malfunctions and cause accidents.
