Wheels and tyres
Wheel rims with bolted trims
Wheel rims may be fitted with interchangea-
ble trim parts which are attached to the rim
using self-locking bolts. Worn trims should
only be replaced at a specialised workshop.
SEAT recommends visiting a technical service
››› .
WARNING
The use of worn or damaged wheel rims could
make driving more dangerous 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 loos-
ened, 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 taking your car
in for technical service. Replacement of wheel rims and new
tyres
New tyres
● When tyres are new, drive with extreme
caution for the first 600 km, as all tyres need
to be run-in . Tyres which have not been run-
in do not
have such good grip ››› or brak-
ing capacity ››› .
● All four wheels must be fitted with radial
tyres of the same type, size (rolling circumfer-
ence) and the same tread pattern.
● The tread depth of new tyres may vary, ac-
cording 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 author-
ised by SEAT for the corresponding type vehi-
cle. Pay special attention to size, diameter,
and maximum 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 maximum braking ca-
pacity to start with, and therefore need run-
ning in.
● To prevent accidents and major damage,
extreme caution should be taken for the first
600 km. WARNING
There should be adequate space between the
tyres and the vehicle in accordance 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 manu-
factured 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 differ-
ent. Note
If you use tyres that are approved by SEAT,
you can be sure that the true tyre dimensions » 161Technical specifications

Foreign bodies in the tyre
● Do not remove foreign bodies if they have
penetrated through the tyre wall!
● You should obtain professional assistance
immediately.
Wear of tyres
The wear of tyres depends on a number of
factors, for example:
● Driving style.
● Unbalanced wheels.
● Running gear settings.
Driving style : Driving round bends quickly or
sudden acceleration or braking speed accel-
erates tyre wear. When the driving style is
normal, if the tyres wear too quickly, have the
running gear settings checked at a special-
ised workshop.
Wheel run-out : The wheels on new vehicles
ar e b
alanced. However, certain circumstan-
ces may lead to imbalance (run-out), which is
detected as vibrations in the steering wheel.
Run-out leads to wear of the steering and
suspension. In the event of run out, the
wheels should be balanced again. When a
new wheel is fitted, it should be balanced
again.
Running gear settings : an incorrectly posi-
tioned running gear increases the wear of
tyres and affects your safety while driving. If tyres wear too quickly, have the wheel align-
ment checked at a specialised workshop. WARNING
If you notice unusual vibration or the car pulls
to one side while driving, this may indicate
that one of the tyres is damaged.
● Reduce speed immediately and stop, while
observing the highway code.
● Check the wheels and tyres for damage.
● Never carry on driving on worn tyres or
wheels. Request qualified assistance immedi-
ately.
● If there is no visible exterior damage, drive
slowly and carefully to the nearest special-
ised workshop and have the vehicle checked. Tyre monitoring system* 
Fig. 117
Centre console: tyre monitor system
button The tyre control lamp compares wheel revolu-
tions and with it, the wheel diameter of each
wheel using the ESC. If the diameter of a
wheel changes, the tyre control lamp

lights up. The wheel diameter changes when:
● Tyre pressure is insufficient.
● The tyre structure is damaged.
● The vehicle is unbalanced because of a
load.
● The wheels of one axle are under more
pressure (for example, driving with a trailer or
on steep slopes).
● The vehicle is fitted with snow chains.
● The temporary spare wheel is fitted.
● The wheel on one axle is changed.
Tyre pressure adjustment
On adjusting tyre pressure or changing one
or more wheels, the ››› Fig. 117 button must
be k ept
pressed down, with the ignition on,
until an acoustic signal is heard.
If the wheels are under excessive load (for ex-
ample, driving with a trailer or heavy load),
the tyre pressure must be increased to the
recommended value for a full load (see the
sticker on the inside of the fuel flap). If the
tyre monitor system button is pressed down,
the new tyre pressures are confirmed.

a)
The letters TIN refer to the tyre serial number.
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. Always observe
the direction of rotation indicated when
mounting the wheel. This guarantees opti-
mum grip and helps to avoid aquaplaning,
grip, noise and wear.
If the tyre is mounted in the opposite direc-
tion of rotation, drive with extreme caution,
as the tyre is no longer being used correctly.
This is of particular importance when the
road surface is wet. Change the tyre as soon
as possible or remount it with the correct di-
rection of rotation.

Advice
Changing a wheel Introduction Some vehicle versions and models do not
have a factory-fitted jack or box spanner. In
this case, we recommend consulting a Speci-
alised workshop to change the wheel.
You should only change the wheels yourself if
the vehicle is parked in a safe place, you are
familiar with the procedure and safety stand-
ards and you have all the necessary tools!
Otherwise, you should seek professional as-
sistance.
WARNING
Changing a wheel can be dangerous, espe-
cially on the hard shoulder. Please observe
the following rules to minimise the risk of in-
jury:
● Stop the vehicle safely as soon as possible.
Park at a safe distance from surrounding traf-
fic to change a wheel.
● When changing a wheel, keep all passen-
gers, and particularly children, a safe dis-
tance away from the work area.
● Turn on the hazard warning lights to warn
other road users.
● Ensure the ground on which you park is flat
and solid. If necessary, support the jack on a
wide solid base. ●
If you are changing a wheel yourself, you
should be familiar with the required proce-
dure. Otherwise, you should seek professio-
nal assistance.
● Only use suitable tools that are not dam-
aged when changing a wheel.
● Always stop the engine, apply the hand-
brake lever firmly and place the selector lever
in position P, or engage a gear for a manual
gearbox to reduce the risk of the vehicle mov-
ing accidentally.
● Have the tightening torque of the wheel
bolts checked as soon as possible with a reli-
able torque wrench. WARNING
If the wheel trims are not appropriate or not
fitted correctly, they could cause major acci-
dents or damage.
● Incorrectly mounted wheel trims may come
off while driving and endanger 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 signifi-
cantly longer braking distances. CAUTION
Remove and remount wheel trims taking care
to avoid damage to the vehicle. Hubcaps

Remove the hubcap of the steel
wheel trim In order to access the wheel bolts, first re-
move the hubcap.
Removing and fitting the hubcap
● To remove , take the vehicle tool kit wire
hook and att
ach it to the edge of the wheel
trim ››› Fig. 124

Raise the vehicle using only the designated
jacking points. WARNING
If the vehicle is not correctly raised, it could
fall off the jack causing serious injury. Please
observe the following rules to minimise the
risk of injury:
● You should only use a jack approved by
SEAT for your vehicle. Other jacks, even those
approved for other SEAT models, might slip
out of place.
● The ground should be firm and flat. If the
ground is sloped or soft then the vehicle
could slip and fall off the jack. If necessary,
support the jack on a wide solid base.
● If the ground is slippery, such as tiles,
place a non-slip surface (a floor mat, for in-
stance) beneath the jack to avoid slipping.
● Only fit the jack at the prescribed jacking
points. The claw of the jack should grip the
reinforcement nerve on the underbody
››› Fig. 130.
● You shou

ld never place a body limb such as
an arm or leg under a raised vehicle that is
solely supported by the jack.
● If you have to work underneath the vehicle,
you must use suitable stands additionally to
support the vehicle, there is a risk of acci-
dent!.
● Never raise the vehicle if it is tilting to one
side or the engine is running.
● Never start the engine when the vehicle is
raised. The vehicle may come loose from the
jack due to the engine vibrations. 177

Tyre repair
TMS (Tyre Mobility System)* The Anti-puncture kit* (Tyre Mobility System)
will reliably seal punctures caused by the
penetration of a foreign body of up to about
4 mm
in diameter.
Do not remove foreign ob-
j

ects, e.g. screws or nails, from the tyre.
After inserting the sealant residue in the tyre,
you must again check the tyre pressure about
10 minutes after starting the engine.
You should only use the tire mobility set if
the vehicle is parked in a safe place, you are
familiar with the procedure and you have the
necessary tire mobility set! Otherwise, you
should seek professional assistance.
The tyre sealant must not be used in the
following cases: ● If the wheel rim has been damaged.

Emergencies
Connect the battery clamps so they have
good metal-to-metal contact with the battery
terminals.
If the engine fails to start, switch off the start-
er after about 10 seconds and try again after
about 1 minute. WARNING
● Please note the safety warnings referring to
working in the engine compartment
››› page 143.
● The b att
ery providing assistance must have
the same voltage as the flat battery (12V) and
approximately the same capacity (see imprint
on battery). Failure to comply could result in
an explosion.
● Never use jump leads when one of the bat-
teries is frozen. Danger of explosion! Even af-
ter the battery has thawed, battery acid could
leak and cause chemical burns. If a battery
freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes
away from batteries, danger of explosion.
Failure to comply could result in an explo-
sion.
● Observe the instructions provided by the
manufacturer of the jump leads.
● Do not connect the negative cable from the
other vehicle directly to the negative terminal
of the flat battery. The gas emitted from the
battery could be ignited by sparks. Danger of
explosion. ●
Do not attach the negative cable from the
other vehicle to parts of the fuel system or to
the brake line.
● The non-insulated parts of the battery
clamps must not be allowed to touch. The
jump lead attached to the positive battery
terminal must not touch metal parts of the ve-
hicle, this can cause a short circuit.
● Position the leads in such a way that they
cannot come into contact with any moving
parts in the engine compartment.
● Do not lean on the batteries. This could re-
sult in chemical burns. Note
The vehicles must not touch each other, oth-
erwise electricity could flow as soon as the
positive terminals are connected. Towing and tow starting
Introduction When towing or tow starting, respect the le-
gal requirements.
For technical reasons, it is not possible to
tow a vehicle if the battery is flat. WARNING
A vehicle with a flat battery should never be
towed.
● Never remove the key from the ignition
lock. Otherwise, the steering wheel lock
could suddenly lock. The vehicle would not
be controlled and a serious accident could
ensue. WARNING
When towing the vehicle, the handling and
braking efficiency change considerably.
Please observe the following instructions to
minimise the risk of serious accidents and in-
jury:
● As the driver of the vehicle being towed:
– The brake must be depressed must hard-
er as the brake servo does not operate.
Always remain aware to avoid collision
with the towing vehicle.
– More strength is required at the steering
wheel as the power steering does not op-
erate when the engine is switched off.
● As the driver of the towing vehicle:
– Accelerate gently and carefully.
– Avoid sudden braking and manoeuvres.
– Brake well in advance than usual and
brake gently.
