Accessories and spare parts
Always consult a SEAT dealership before purchasing acces-
sories and parts.
Your vehicle is designed to offer a high standard of active and passive safe-
ty.
Before purchasing accessories and parts, and before making technical
changes to your vehicle, we recommend that you consult your Technical
Service.
SEAT dealerships will be happy to provide you with the latest information
about the use, legal requirements and recommendations from the manufac-
turer regarding accessories and spare parts.
We recommend you use only SEAT Approved Accessories®
and SEAT Ap-
proved Spare Parts ®
. This way, SEAT can guarantee that the product in
question is suitable, reliable and safe. SEAT Technical Services have the
necessary experience and facilities to ensure that parts are correctly and
professionally installed.
Despite a continuous observation of the market, SEAT is not able to assess
the reliability, safety and suitability of parts that SEAT has not approved. For
this reason, SEAT cannot assume responsibility for any non-genuine parts
used, even if these parts have been approved by an official testing agency
or are covered by an official approval certificate.
Any equipment subsequently installed which has a direct effect on the driv-
er's control of the vehicle (e.g. cruise control system or electronically-con-
trolled suspension) must be approved by SEAT and bear the e mark (the Eu-
ropean Union's authorisation symbol). If any
additional electrical components are fitted which do not serve to con-
trol the vehicle itself (e.g. refrigerator box, laptop or ventilator fan), these
must bear the CE mark (European Union manufacturer conformity declara-
tion).
WARNING
Accessories, for example telephone holders or cup holders, should never
be fitted on the covers, or within the working range, of the airbags. Oth-
erwise, 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 or software in the
vehicle may cause malfunctions. Due to the way the electronic components
are linked together in networks, other indirect systems may be affected by
the faults. This can seriously impair safety, lead to excessive wear of compo-
nents, and also invalidate your vehicle registration documents.
SEAT Technical Services cannot be held liable for any damage caused by
modifications and/or work incorrectly performed.
For this reason, we recommend having all work performed by a SEAT Techni-
cal Service using SEAT Original Spare Parts ®

224Checking and refilling levels
Tyre useful life
The useful life of tyres is dependent on tyre pressure, driving
style and fitting.
Fig. 145 Tyre tread wear
indicators
Fig. 146 Diagram for
changing wheels Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
⇒ Fig. 145, running across the tread. Depending on the make, there will be
6 to 8 of them evenly spaced around the tyre. Markings on the tyre sidewall
(for instance the letters “TWI” or other symbols) indicate the positions of
the tread wear indicators. The minimum tread depth required by law is
1.6 mm (measured in the tread grooves next to the tread wear indicators).
Worn tyres must be replaced. Different figures may apply in export countries
⇒ 
.
Tyre pressure
Incorrect tyre pressure causes premature wear and could cause tyre blow-
out. For this reason, the tyre pressure should be checked at least once per
month ⇒ page 223.
Driving style
Fast cornering, heavy acceleration and hard braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more than the rear ones it is advisa-
ble to change them around as shown ⇒ Fig. 146. The useful life of all the
tyres will then be about the same time.
Wheel balance
The wheels on new vehicles are balanced. However, various factors encoun-
tered in normal driving can cause them to become unbalanced, which re-
sults in steering vibration.
Unbalanced wheels should be rebalanced, as they otherwise cause exces-
sive wear on steering, suspension and tyres. A wheel must also be reba-
lanced when a new tyre is fitted.
Incorrect wheel alignment
Incorrect wheel alignment causes excessive tyre wear, impairing the safety
of the vehicle. If tyres show excessive wear, you should have the wheel
alignment checked by a Technical Service. 

Urban consumption and CO 2 emissions
B Extra-urban consumption and CO 2 emissions
C Combined consumption and CO 2 emissions
Chassis number
The vehicle identification number can be read from outside the vehicle
through a viewer in the windscreen ⇒ Fig. 193. The viewer is located near
the lower corner of the windscreen. The chassis number is printed on the
right water drain channel. The water drain channel is located between the
suspension tower and the wing. To access the chassis number, open the
bonnet ⇒ page 206. 
Information on fuel consumption
Fuel consumption and emissions of CO 2
The consumption and emission details shown on the vehicle
data sticker differ from one vehicle to another.
The vehicle fuel consumption and CO 2 emissions can be consulted on the
vehicle data sticker in the spare wheel well, inside the luggage compart-
ment and on the rear cover of the Maintenance Programme.
The fuel consumption and CO 2 emission values refer to the weight category
assigned to your vehicle according to the engine and gearbox combination,
as well as the specific equipment fitted, and is only used to compare be-
tween the different models.
The fuel consumption and CO 2 emissions do not depend only on the per-
formance of the vehicle, they can also differ from the established values de-
pending on other factors such as driving style, road conditions, traffic con-
ditions, environmental conditions, load and number of passengers. 5
Calculation of fuel consumption
The consumption values have been calculated based on measurements per-
formed or supervised by certified CE laboratories according to the latest ver-
sion of directives 715/2007/EC and 80/1268/CEE (for more information
consult the European Union Publications Office at EUR-Lex: © European Un-
ion, http://eur-lex.europa.eu/en/index.htm) and are valid for the kerb
weight indicated for the vehicle.
Note
In practice, and considering all the factors mentioned here, consumption
values can differ from those calculated in the current European regulations. 
