Accessories, parts replacement and modifications
224Accessories, parts replacement and modificationsAccessories and spare partsAlways consult an Authorised Service Centre before 
purchasing accessories and parts.Your vehicle is designed to offer a high standard of active and passive safety.
Before purchasing accessories and parts, and before making technical 
changes to your vehicle, we recommend you to consult your Authorised 
Service Centre.
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 parts.
We recommend you use only  SEAT Approved Accessories
® and SEAT 
Approved Spare Parts
®. This way, SEAT can guarantee that the product in 
question is suitable, reliable and safe. SEAT Authorised Service Centres 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 those parts  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 
driver’s control of the vehicle (e.g. cruise control system or electronically-
controlled suspension) must be approved by SEAT and bear the  e mark (the 
European Union’s authorisation symbol). Any 
additional electrical components  that do not affect the control of the 
vehicle itself (e.g. refrigerator box, laptop, ventilator fan, etc.), must bear the 
CE  mark (European Union manufacturer conformity declaration).
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 modificationsModifications 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 Authorised Service Centres cannot be held liable for any damage 
caused by modifications and/or work incorrectly performed.
For this reason, we recommend that all work should be performed by an 
Authorised Service Centre using  Genuine SEAT 
® approved parts and acces-
sories .

Wheels and tyres
252Wear indicators
The original tyres on your vehicle have 1.6 mm high tread wear indicators 
⇒ page 251, fig. 172 , 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 indica-
tors). 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 249.
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 advisable 
to change them around as shown  ⇒page 251, fig. 173. All the tyres will then 
last for 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 results 
in steering vibration.
Unbalanced wheels should be rebalanced, as they otherwise cause excessive 
wear on steering, suspension and tyres. A wheel must also be rebalanced 
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 align-
ment checked by an Authorised Service Centre.
WARNING
There is a serious danger of accidents if a tyre bursts during driving!•The tyres must be replaced at the latest when the tread is worn down to 
the tread wear indicators. Failure to do so could result in an accident. Worn 
tyres do not grip well at high speeds on wet roads. There is also a greater 
risk of aquaplaning.•At continuously high speeds, a tyre with insufficient pressure flexes 
more. This causes it to overheat. This can cause tread separation and tyre 
blow-out. Risk of accident. Always observe the recommended tyre pres-
sures.•I f  t y r e s  s h o w  e x ce s s i v e  w e a r,  y o u  s h o u l d  h a v e  t h e  r u n n i n g  g e a r  ch e cke d  
by an Authorised Service Centre.•Keep chemicals such as oil, fuel and brake fluid away from tyres.•Damaged wheels and tyres must be replaced immediately!For the sake of the environment
Under-inflated tyres will increase fuel consumption.Run-flat tyres
Run-flat tyres allow you to continue driving even with a punc-
tured tyre, in the majority of cases.In vehicles that are factory-fitted with run-flat tyres
25) the loss of tyre 
pressure is indicated on the instrument panel.
