Safety First Operating instructions Practical tips Technical Data
The storing of the data allows specialised workshops to detect and repair
faults. Stored data may include:
x Data relating to the engine or the gearbox
x Speed
x Direction of travel
x Braking force
x Detection of seat belt
The vehicle control units never record conversations held by passengers in
the vehicle.
In vehicles equipped with an emergency call function via the mobile phone or
other appliances connected in the vehicle, it is possible to send the vehicle
position. 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 good
coverage.
Event Data Recorder
The vehicle is not fitted with an event data recorder.
An event data recorder temporarily stores the vehicle information. Therefore,
in the event of accident, it is possible to obtain detailed information about
how the accident occurred. For example, in vehicles with airbag systems,
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 manufac-
turer.
Event data recorders can only be mounted with authorisation from the vehicle
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 stored
in the control units. The programming of certain convenience functions, such
as the convenience indicators, individual door opening and instructions on
the display can be modified using special equipment at the workshop. If this
is the case, the information and descriptions given in the instructions manual
will not match the original functions. Therefore, SEAT recommends that any
modifications are recorded in the section “Other workshop notes” in the
Maintenance Programme.
The Technical Service must have a record of any modification to the program-
ming.
Reading the vehicle fault memory
There is a diagnostics connector in the vehicle interior for reading the vehicle
fault memory. The fault memory documents errors and deviations from the
theoretical values of the electronic control units.
The diagnostics connector is in the driver's side footwell area, next to the
lever for opening the bonnet, below a cover.
The fault memory should only be read and reset by a qualified workshop.
Using a mobile telephone in a vehicle without connection to
an exterior aerial
Mobile telephones transmit and receive radio waves, both when in use and
when on stand-by. Scientific studies state that radio waves exceeding certain
values may be harmful to the human body. International committees and
authorities have established limits and directives in order to ensure electro-
magnetic radiation from mobile phones remains within certain limits that do
not endanger human health. However, there is no available conclusive scien-
tific evidence that cordless phones are completely safe.
Therefore, some experts recommend that use of mobile phone be kept to a
minimum until the results of current research are published.
When a mobile phone not connected to an exterior aerial is used inside the
vehicle, the electromagnetic radiation may be greater than if the mobile
phone were connected to a built-in aerial or to another exterior aerial.
