WARNING
The vehicle cannot be totally controlled or braked if the tyres (new or
used) are worn or damaged.
● Incorrect use of wheels and tyres could make driving more dangerous
and result in serious accidents and damage.
● All four wheels must be fitted with radial tyres of the same type, size
(rolling circumference) and the same tread pattern.
● New tyres do not give maximum grip and will not have reached their
maximum braking capacity to start with, and therefore need running in.
To prevent accidents and major damage, extreme caution should be tak-
en for the first 600 km (400 miles).
WARNING (Continued)
● Check tyre pressures regularly and ensure they are maintained at the
pressures indicated. If the tyre pressure is too low, the tyres could over-
heat, resulting in tread detachment or even burst tyres.
● Never drive on damaged (punctured, cut, cracked or dented) or worn
tyres. Driving on damaged or worn tyres could result in burst tyres, seri-
ous accidents or damage. Worn or damaged tyres must be replaced im-
mediately.
● Never exceed the maximum permitted speed or loads specified for the
type of tyre fitted on your vehicle.
● The effectiveness of driver and brake assist systems also depends on
the grip of the tyres.
● If you notice unusual vibration or if the vehicle pulls to one side when
driving, stop the car immediately and check the tyres and wheels for
damage.
● To minimise the risk of losing control of the vehicle or causing a seri-
ous accident, never undo the bolted joints of beadlock wheels.
● Never mount used tyres or wheels if you are not sure of their previous
history. They may be damaged, although the damage is not immediately
visible.
● Old tyres, even if they have never been used, may lose air or burst un-
expectedly while driving, especially at high speeds, resulting in serious
accident and injury. If tyres are over six years old, they should only be
used in an emergency and with extreme caution.
Note
For technical reasons, it is not generally possible to use the wheels from
other vehicles. In some cases, this may also be true for the same model of
wheel. Please refer to the vehicle documentation or ask at a Technical Serv-
ice. 

Vehicle care and maintenance
About your tyres and wheels
Fig. 123 Diagram for
changing wheels
The tyres of a vehicle are the components which are subjected to most
stress and are the most underestimated. Tyres are very important, as the
support offered by their narrow surface is the only point of contact between
the vehicle and the road.
The service life of tyres is dependent on tyre pressure, driving style, the care
they receive and the correct fitting.
The tyres and wheel rims are an essential part of the vehicle's design. The
tyres and rims approved by SEAT are specially matched to the characteris-
tics of the vehicle and our critical to good road holding and safe handling.
Avoiding damage to tyres and wheels
● If you have to drive over a kerb or similar obstacle, drive very slowly and
as near as possible at a right angle to the kerb.
● Inspect the tyres regularly for damage (punctures, cuts, cracks, dents).
● Remove any foreign bodies found on the outside of the tread provided
they have not passed through the wall of the tyre
⇒  page 216.
● The instructions for tyre control systems should always be observed. ●
Replace damaged or worn tyres as soon as possible ⇒ page 216.
● Regularly check tyres for non-visible damage ⇒ page 216.
● Never exceed the maximum permitted speed or loads specified for the
type of tyre fitted on your vehicle ⇒ page 218.
● Do not allow tyres (including the spare wheel) to come into contact with
aggressive substances, grease, oil, fuel or brake fluid ⇒ 
.
● Lost valve caps should be replaced immediately.
Tyres with directional tread pattern
Tyres with directional tread pattern have been designed to operate best
when rotating in only one direction. An arrow on the tyre sidewall indicates
the direction of rotation on tyres with directional tread ⇒ page 218. Always
observe the direction of rotation indicated when mounting the wheel. This
guarantees optimum grip and helps to avoid aquaplaning, excessive noise
and wear.
If the tyre is mounted in the opposite direction of rotation, drive with ex-
treme caution, as the tyre is no longer being used correctly. This is of partic-
ular importance when the road surface is wet. Change the tyre as soon as
possible or remount it with the correct direction of rotation.
Interchanging tyres
To ensure that the wear is equal on all tyres the wheels should be changed
round from time to time according to the system ⇒ Fig. 123. The useful life
of all the tyres will then be about the same time.
SEAT recommends you take the vehicle to a specialised workshop to have
the tyres changed.
Tyres that are over 6 years old
Tyres are subject to an ageing process as a result of physical and chemical
processes. This may affect their performance. Tyres which are stored for
long periods of time without being used, harden and become more fragile
than tyres which are in constant use.
SEAT recommends that tyres over six years old are replaced with new tyres.
This also applies to tyres (including the spare wheel) which appear to be in 

nanceIf and whenTechnical specifications

212Vehicle care and maintenance
perfect condition on the outside and which have a tread depth within the
values stipulated by the Law ⇒ 
.
The date of manufacture, part of the tyre identification number (TIN), indi-
cates the age of the tyre ( ) ⇒ page 218.
Storing tyres
Mark tyres when you remove them to indicate the direction of rotation (left,
right, forwards, backwards). This ensures you will be able to mount them
correctly when you replace them. When removed, the wheels and/or tyres
should be stored in a cool, dry and preferably dark location. Do not place
tyres mounted on the wheel in a vertical position.
Protect tyres not mounted on wheels from dirt by storing them in suitable
bags and standing them on the ground on their tread.
WARNING
Aggressive fluids or substances could result in visible or invisible dam-
age with the consequent risks.
● Always ensure that tyres do not come into contact with chemical
products, oil, grease, fuel, brake fluid or other aggressive substances.
WARNING
Old tyres, even if they have never been used, may lose air or burst unex-
pectedly while driving, resulting in serious accident or damage.
● If tyres are over six years old, they should only be used in an emer-
gency and with extreme caution.
For the sake of the environment
Old tyres must be disposed of by qualified personnel according to the laws
in the country concerned. Wheel rims
The design of wheel bolts is matched to the rims. If different rims are fitted,
the correct wheel bolts with the right length and correctly shaped bolt
heads must be used. This ensures that wheels are fitted securely and that
the brake system functions correctly
⇒ page 252.
For technical reasons, it is not generally possible to use the wheels from
other vehicles. In some cases, this may also be true for the same model of
wheel.
The tyres and rims approved by SEAT are specially matched to the character-
istics of the vehicle and are critical to good road holding and safe handling.
Wheel bolts
Wheel bolts must be tightened to the correct torque ⇒ page 252.
Beadlock wheel rims
Beadlock wheel rims have various components. These are joined together
by special bolts using a special procedure. This ensures good performance,
a better seal, improved safety and wheel run out. Therefore, worn rims
should always be replaced and must only be repaired in a specialised work-
shop. SEAT recommends visiting a Technical Service ⇒ 
.
Wheel rims with bolted trims
Wheel rims may be fitted with interchangeable trim parts which are attach-
ed to the rim using self-locking bolts. Worn trims should only be replaced at
a specialised workshop. SEAT recommends visiting a Technical Service
⇒ 
. 

213
Vehicle care and maintenance
WARNING
The use of worn or damaged wheel rims could make driving more danger-
ous and result in serious accidents and damage.
● Only wheel rims which have been approved for use with your vehicle
should be used.
● Inspect wheel rims regularly for damage and replace as required.
WARNING
If the bolted joints of wheel rims with bolted ring trims are not correctly
tightened or loosened, this could result in serious accident.
● Never loosen the bolted joints of wheel rims with bolted ring trims.
● Any work relating to wheel rims with bolted rims should be carried
out at specialised workshop. SEAT recommends visiting a Technical Serv-
ice.

Replacement of new tyres and wheel rims
New tyres
● When tyres are new, drive with extreme caution for the first 600 km
(400 miles), as all tyres need to be run-in. Tyres which have not been run-in
do not have such good grip ⇒ 
or braking capacity ⇒ .
● All four wheels must be fitted with radial tyres of the same type, size
(rolling circumference) and the same tread pattern.
● The tread depth of new tyres may vary, according to the type and make
of tyre and the tread pattern. Replacing tyres
●
Where possible, always replace both wheels on an axle (both wheels on
the front axle or both wheels on the rear axle) ⇒ 
.
● Only replace used tyres with those authorised by SEAT for the corre-
sponding type vehicle. Pay special attention to size, diameter, and maxi-
mum load and speed capacity.
● Never use tyres which are larger than SEAT approved tyres. If the tyres
are too big, they may knock or rub against the chassis or other components,
resulting in damage.
WARNING
New tyres do not give maximum grip and will not have reached their max-
imum braking capacity to start with, and therefore need running in.
● To prevent accidents and major damage, extreme caution should be
taken for the first 600 km (400 miles).
WARNING
There should be adequate space between the tyres and the vehicle in ac-
cordance with the vehicle design. If this is not the case, the tyres may
rub against parts of the running gear, chassis or brake lines, leading to
faults in the brake system or to tread detachment, and the risk of burst
tyres.
● The true tyre dimension should not be greater than the dimensions of
tyres manufactured and approved by SEAT and should not rub against
parts of the vehicle.
Note
Although tyres may be shown as being the same size, the true dimensions
of different types of tyre may vary with respect to the nominal size, or tread
patterns may be different. 

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 rims ⇒ 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.

242Practical information
Checklist (Continued) 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 on, a change in direction
or traffic lane can be indicated as usual using the turn signal lever. The haz-
ard lights will be interrupted temporarily.
Examples of when to use the hazard warning lights:
● 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 are not working, you must use an alternative
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 will be
automatically turned off. 

Wheel trims
Introduction
Additional information and warnings:
● Caring for and cleaning the vehicle exterior ⇒ page 197
● Vehicle tools ⇒ page 247
● Change wheel ⇒ page 252
● Tire Mobility Set ⇒ page 258
WARNING
If the wheel trims are not appropriate or not fitted correctly, they could
cause major accidents or damage.
● Incorrectly mounted wheel trims may come off while driving and en-
danger other road users.
● Damaged trims must never be mounted on the wheels.
● Always ensure that the brake ventilation and cooling is not cut off or
blocked. This is also valid if hubcaps are fitted later. If there is not
enough air, you may require significantly longer braking distances.
CAUTION
Remove and remount wheel trims taking care to avoid damage to the vehi-
cle. Hubcaps
Fig. 141 Remove the
hubcap of the steel wheel
trim
In order to access the wheel bolts, first remove the hubcap.
Removing and fitting the hubcap
● To remove, take the vehicle tool kit wire hook and attach it to the edge of
the wheel trim ⇒ Fig. 141.
● Remove the trim by pulling it in the direction of the arrow.
● To replace the hubcap , press the hubcap against the trim until it clicks
into place.
The caps protect the wheel bolts and should be remounted after changing
the tyre. 
