Vehicle care and maintenance
Remove wheel hub covers and trim rings before fitting snow chains ⇒
.
The wheel bolts should be covered with caps for safety reasons. These are
available from Technical Services.
Temporary spare wheel
For technical reasons, snow chains must not be used on the compact tem-
porary spare wheel ⇒ page 217.
If it is necessary to fit chains with the temporary spare wheel in use, install
the temporary spare wheel on the rear axle in the event of a fault in a front
wheel. Then, fit the rear wheel that is free, instead of the damaged front
wheel. In this situation, observe the rotating direction of the wheels. SEAT
recommends attaching the snow chains before fitting the wheel.
WARNING
The use of unsuitable or incorrectly fitted chains could lead to serious ac-
cidents and damage.
● Always the appropriate snow chains.
● Observe the fitting instructions provided by the snow chain manufac-
turer.
● Never exceed the maximum permitted speeds when driving with snow
chains.
CAUTION
● You must remove the snow chains to drive on roads which are free of
snow. Otherwise they will impair handling, damage the tyres and wear out
very quickly.
● Wheel trims may be damaged or scratched if the chains come into direct
contact with them. SEAT recommends the use of covered snow chains.
Note
Snow chains are available in different sizes according to the vehicle type.

Vehicle care and maintenance
Running-in
Please observe the instructions for running-in new components.
Running-in the engine
The engine needs to be run in over the first 1500 km (1000 miles). During
its first few hours of running, the internal friction in the engine is greater
than later on when all the moving parts have bedded down.
How the vehicle is driven for the first 1500 km (1000 miles) influences the
future engine performance. Throughout the life of the vehicle, it should be
driven at a moderate speed, especially when the engine is cold, as this will
reduce engine wear and increase its useful life. Never drive at extremely low
engine speeds. Change down to a lower gear when the engine no longer
runs “smoothly”. Up to 1000 kilometres the following instructions apply:
● Do not use full throttle.
● Do not force the engine above two thirds of its maximum speed.
Between 1000 and 1500 kilometres (600 to 1000 miles), gradually in-
crease power until reaching the maximum speed and high engine speeds.
Running in new tyres and brake pads
● Replacement of new tyres and wheel trims ⇒ page 210
● Notes on the brakes ⇒ page 134
For the sake of the environment
If the engine is run in gently, the life of the engine will be increased and the
engine oil consumption reduced.
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 SEAT Official Service
will advise you as to the legal requirements and manufacturer's recommen-
dations 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 SEAT Technical
Service 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 vehicle control must
be approved by SEAT for use in your vehicle and bear the e mark (the Euro-
pean 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 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 trig-
gered.

Vehicle care and maintenance
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 Specialised work-
shop. These components may contain parts or sensors belonging to the air-
bag 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.

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

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.

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.
