Accessories, parts replacement and modificationsAccessories and 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 car, we recommend that you 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. Authorised Service Centres have the 
necessary experience and facilities to ensure that parts are installed correctly 
and professionally.
Despite continuous observation of the market, SEAT is not able to assess the 
reliability, safety and suitability of parts  not approved by SEAT. 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 
vehicle and/or the way it is driven (e.g.  cruise control system or electronically-
controlled suspension) must be approved by SEAT for use in your vehicle and 
bear the  e mark (the European Union's authorisation symbol).
If any additional electrical components  are fitted which do not serve to 
control the vehicle itself (for instance a refrigerator box, laptop or ventilator  fan, etc.), these must bear the 
CE mark (European Union manufacturer 
conformity declaration).
WARNING
Accessories, for example telephone holders or drink holders, should never 
be fitted on the covers of, or within the working range of, the airbags. If 
they are, there is a danger of resulting injury if the airbag is triggered in an 
accident.ModificationsModifications must always be carried out according to our 
specifications.Unauthorised modifications to the electr onic components or software in the 
vehicle may cause malfunctions. Due to the way the electronic components 
are linked together in networks, other systems may be affected by the faults. 
This can seriously impair safety, lead to excessive wear of components, and 
also invalidate your vehicle registration documents.
SEAT Authorised Service Centres cannot be held liable for any damage 
caused by modifications and/or work performed incorrectly.
For this reason, we recommend that all work should be performed by an 
Authorised Service Centre using  genuine and SEAT
® approved parts and 
accessories .

Checking and refilling levels
194Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators” 
⇒ page 193, fig. 134  running across the tread. Depending on the make, 
there will be six to eight 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. D ifferent 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 193.
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 193, fig. 135. 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 tyre s. A wheel must also be rebalanced 
when a new tyre is fitted.
Incorrect wheel alignment
Incorrect wheel alignment causes excessiv e 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.
•
If tyres show excessive wear, you should have the running gear checked 
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.New tyres and wheels
New tyres and wheels have to be run-in.The tyres and wheel rims are an essenti al part of the vehicle's design. The 
tyres and rims approved by SEAT are specially matched to the characteristics 
of the vehicle and make a major contribution to good road holding and safe 
handling  ⇒.
Tyres should be replaced at least in pairs and not individually (i.e. both front 
tyres or both rear tyres together). A knowledge of tyre designations makes it
