Vehicle care and maintenance
In vehicles equipped with an emergency call function via the mobile tele-
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 acti-
vation, 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. 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 convenience indicators, individual door opening and instruc-
tions on the display can be modified using special equipment at the work-
shop. If the comfort functions are reprogrammed, the information and In-
struction Manual descriptions will not coincide with the modified functions.
Therefore, SEAT recommends that any modifications are recorded in the sec-
tion “Other workshop notes” in the Maintenance Programme.
The SEAT Official Service must have a record of any modification to the pro-
gramming.
Reading the vehicle fault memory
There is a diagnostics connector in the vehicle interior for reading the vehi-
cle 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 side footwell area, next to the lev-
er for opening the bonnet, below a cover.
The fault memory should only be read and reset by a Specialised workshop.

Using a mobile telephone in a vehicle without connection
to an exterior aerial
Mobile telephones transmit and receive radio waves also called high-fre-
quency energy, both when in use and when on stand-by. Scientific studies
state that radio waves exceeding certain values may be harmful to the hu-
man body. International committees and authorities have established limits
and directives in order to ensure electromagnetic radiation from mobile
phones remains within certain limits that do not endanger human health.
However, there is no available conclusive scientific evidence that cordless
phones are completely safe.
That is why some experts recommend moderate use of the mobile tele-
phone, and the appliance of measures to reduce radiation on the human
body.
When a mobile telephone 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.
If the vehicle is fitted with a suitable hands-free device that allows the em-
ployment of numerous additional mobile telephone functions with compati-
ble Bluetooth technology ®
, it will comply with the legislation in many coun-
tries which only permits the use of mobile phones inside vehicles using a
hands-free device.
The hands-free system of the Portable Navigation System (supplied by
SEAT) has been designed for use with conventional mobile phones and
phones with Bluetooth technology ®
⇒ page 229. Mobile telephones must
be placed in a suitable telephone support or stored safely in the vehicle. If a
support is used for the telephone, it must be securely fastened to the base 

Always use the jacking points indicated in the figures ⇒ Fig. 127 and
⇒ Fig. 128 when raising the vehicle. If the vehicle is not lifted at these
points, it could be seriously damaged ⇒ 
or lead to serious injury ⇒ .The vehicle should not be lifted using lifting platforms with lift pads con-
taining fluid.
When raising a vehicle using a platform or jack, a series of precautionary
measures are required. Never raise the vehicle with a lifting platform or jack
unless you have received training in how to do so and know how to lift the
vehicle safely.
Notes on raising the vehicle with a jack
⇒ page 250.
WARNING
The improper use of the lifting platform or the jack when raising the vehi-
cle may result in accidents or serious injury.
● Before raising the vehicle, please observe the manufacturer's instruc-
tions for the platform or jack, and the legal requirements, where applica-
ble.
● There should not be anyone inside the vehicle when it is being raised
or once it is in the air.
● Only use the jacking points indicated in the figures ⇒ Fig. 127 and
⇒ Fig. 128 when raising the vehicle. If the vehicle is not lifted at the indi-
cated points, it may fall from the platform while the engine or gearbox is
being dismounted, for example.
● The jacking points should be centrally aligned and firmly positioned
on the platform support plates.
● Never start the engine when the vehicle is raised! The vehicle may fall
from the platform due to the engine vibrations.
● If it is necessary to work underneath the vehicle while it is raised, you
should check that the supporting stands have an adequate load capacity.
● Never climb onto the lifting platform.
● Always make sure that the weight of the vehicle does not exceed the
lifting platform load capacity. 

Collection and scrapping of end-of-life vehicles
Collection of end-of-life vehicles
SEAT is already prepared for the moment when you wish to scrap your vehi-
cle and offers you an environmentally-friendly solution. An extensive net-
work of used vehicle reception centres already exists in much of Europe. Af-
ter the vehicle has been delivered, you will receive a certificate of destruc-
tion describing the environmentally friendly scrapping of the vehicle in ac-
cordance with applicable legislation.
We will collect the used vehicle free of charge, provided it complies with all
national legislation.
Please see your Technical Service for further information about the collec-
tion and scrapping of end-of-life vehicles.
Scrapping
The relevant safety requirements must be observed when the vehicle or
components of the airbag or belt tensioner systems are scrapped. These re-
quirements are known to qualified dealerships. 

Vehicle care and maintenance
Catalytic converter
The catalytic converter permits the subsequent treatment of the exhaust
gases thus reducing contaminating gas emissions. To ensure a longer work-
ing life for the exhaust system and catalytic converter in a petrol engine:
● Always use unleaded petrol.
● Never run the fuel tank completely dry.
● Do not top up with too much engine oil ⇒ page 185.
● Do not tow-start the vehicle; use the starter cables ⇒ page 273.
If you should notice misfiring, uneven running or loss of power when the ve-
hicle is moving, reduce speed immediately. Have the vehicle inspected by a
Specialised workshop. If this happens, unburnt fuel can enter the exhaust
gas system and escape into the atmosphere. The catalytic converter can al-
so be damaged by overheating.
For the sake of the environment
Even when the emission control system is working perfectly, there may be a
smell of sulphur from the exhaust gas under some conditions. This depends
on the sulphur content of the fuel used. 

Practical information
Checklist (Continued) 7. When leaving the vehicle, take all keys with you.
8. Place an emergency warning triangle to indicate the position of your vehicle to other road users.
9. Allow the engine to cool and check if a specialist is required.
When being towed with the hazard warning lights system on, a change in
direction or traffic lane can be indicated as usual using the turn signals lev-
er. The hazard lights will be interrupted temporarily.
Examples of when to use the hazard warning lights system:
● If the vehicles ahead suddenly slow down or reach the end of a traffic
jam, to warn the vehicles behind.
● In case of an emergency.
● If the vehicle breaks down.
● When tow-starting or towing.
Always comply with the applicable laws regarding the use of hazard warn-
ing lights.
If the hazard warning lights system is not working, you must use an alterna-
tive method of drawing attention to your vehicle. This method must comply
with traffic legislation.
WARNING
Failure to follow the checklist prepared for your own safety could lead to
accidents and severe injuries.
● Always complete the operations given in the checklist and observe
the general rules of safety.
WARNING
The components of the exhaust system reach very high temperatures.
This could cause a fire and considerable damage.
● Always park your vehicle so that no part of the exhaust system can
come in contact with flammable materials (such as dried grass or fuel).
Note
The vehicle battery will discharge and run down if the hazard warning lights
remain on for too much time (even with the ignition turned off).
Note
For some vehicles, the brake lights will blink when braking suddenly at
speeds of approximately 80 km/h (50 mph) to warn vehicles behind. If brak-
ing continues, then the hazard warning lights system will automatically be
turned on at the speed of less than approximately 10 km/h (6 mph). The
brake lights remain lit. Upon accelerating, the hazard warning lights system
will be automatically turned off. 
