● The v
ehicle is not designed for the use of
FAME fuel (biodiesel). The fuel system would
be damaged if you used biodiesel.
● Do not mix fuel additives, the so-called
“thinners”, petr
ol or similar additives with
diesel fuel.
● If poor-quality diesel fuel is used, it may be
nece
ssary to drain the fuel filter more fre-
quently than is specified in the Maintenance
Programme. We recommend having this done
by a specialised workshop. If water is allowed
to collect in the filter, this can cause engine

WARNING
● Sw it
ch the engine off, remove the key from
the ignition and apply the hand brake. If the
vehicle has a manual gearbox, place the lever
in neutral; if it has an automatic gearbox,
place the selector lever in position P. Wait for
the engine to cool down.
● Keep children away from the engine com-
par
tment.
● Never spill liquids used for vehicle opera-
tion on the engine c
ompartment, as these
may catch fire (e.g. the antifreeze in coolant).
● Take care not to cause short circuits in the
electric
al system, especially when working
on the battery.
● If working inside the engine compartment,
remember th
at, even when the ignition is
switched off, the radiator fan may start up au-
tomatically, and therefore there is a risk of in-
jury.
● Never cover the engine with additional in-
su
lating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pan
sion tank when the engine is hot. The
cooling system is under pressure.
● Protect face, hands and arms by covering
the cap w
ith a large, thick rag to protect
against escaping coolant and steam.
● If it is necessary to work in the engine com-
par
tment while the engine is running, the ro-
tating components (for example, poly-V belt, alternator, radiator fan) and the high voltage
ignition sy
s

tem are an additional hazard.
● Observe the following additional warnings
if w
ork on the fuel system or the electrical
system is necessary:
– Always disconnect the battery from the
on-board network.
– Do not smoke.
– Never work near naked flames.
– Always keep an approved fire extinguish-
er immediately available. CAUTION
When topping up fluids make sure the correct
fluid i s

put into the correct filler opening, oth-
erwise this can cause serious malfunctions or
engine damage. For the sake of the environment
Inspect the ground underneath your vehicle
r e

gularly so that any leaks are detected at an
early stage. If you find spots of oil or other
fluids in the area where it was parked, have
your vehicle inspected at the workshop. Note

other type of battery is fitted, the Start-Stop
function may be considerably reduced and
the vehicle may not stop on repeated occa-
sions.
● Make sure that the vent hose is always at-
tac
hed to the original opening on the side of
the battery. Gases or battery acid can other-
wise escape and possibly cause damage.
● The battery holder and clamps must always
be corr
ectly secured.
● Before starting any work on the battery, al-
wa
ys observe the warnings listed under

Wheel s

and tyres
General notes –
When driving with new ty r
es, be especially
careful during the first 500 km (300 miles).
– If you have to drive over a kerb or similar
ob

stacle, drive very slowly and as near as
possible at a right angle to the obstacle.
– Check from time to time if the tyres are
dam

aged (punctures, cuts, cracks or
dents). Remove any foreign objects embed-
ded in the treads.
– Damaged wheels and tyres must be re-
pl

aced immediately.
– Keep grease, oil and fuel off the tyres.
– Replace any missing valve caps as soon as
pos

sible.
– Mark the wheels before taking them off so
that

they rotate in the same direction when
put back.
– When removed, the wheels or tyres should
be st

ored in a cool, dry and preferably dark
place.
New tyres
New tyres do not give maximum grip straight
away and should therefore be “run in” by driving carefully and at moderate speeds for
about the fir

st 500 km (300 miles). This will
also increase the useful life of the tyres.
The tread depth of new tyres may vary, ac-
cording to the type and make of tyre and the
tread pattern.
Concealed damage
Damage to tyres and rims is often not readily
visible. If you notice unusual vibration or the
car pulling to one side, this may indicate that
one of the tyres is damaged. Reduce speed
immediately if there is any reason to suspect
that damage may have occurred. Inspect the
tyres for damage. If no external damage is
visible, drive slowly and carefully to the near-
est specialised workshop and have the car
inspected.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the di-
rection of rotation on single drive tyres. Al-
ways note the direction of rotation indicated
when mounting the wheel. This guarantees
optimum grip and helps to avoid aquaplan-
ing, excessive noise and wear.
Retrofitting accessories
If you wish to change or fit wheels, rims or
wheel trims, we recommend that you consult
with a SEAT Official Service centre for advice
regarding current techniques.

Tyre useful life Fig. 224
Location of the tyre pressure sticker. Correct inflation pressures and sensible driv-
in
g h
abits will increase the useful life of your
tyres.
– Check tyre pressure at least once a month,
and also prior t

o any long trip.
– The tyre pressure should only be checked
when the tyr

es are cold. Do not reduce the
pressure of warm tyres.
– Adjust tyre pressure to the load being car-
ried by

the vehicle. –
In v
ehicles with a tyre pressure indicator,
save the pressure of modified tyres
››› page 295, ››› page 292.
– Avoid fast cornering and hard acceleration.
– Inspect the tyres for irregular wear from
time to time.
The u

seful life of your tyres depends on the
following factors:
Tyre pressure
The tyre inflation pressures are listed on a
sticker inside the driver door pillar
››› Fig. 224.
Insufficient or excessive pressure greatly re-
duces the useful life of the tyres and adverse-
ly affects vehicle performance and ride. Cor-
rect inflation pressures are very important,
especially at high speeds.
Depending on the vehicle, tyre pressure can
be adjusted to medium load to improve driv-
ing comfort (“comfort” tyre pressure). When
driving with comfort tyre pressure fuel con-
sumption may increase slightly.
The tyre pressure must be adjusted according
to the load the vehicle is carrying. If the vehi-
cle is going to carry the maximum load, the
tyre pressure should be increased to the max-
imum value indicated on the sticker
››› Fig. 224. Do not forget the spare wheel when checking
the tyr

e pressures: Keep this spare wheel in-
flated to the highest pressure required for the
road wheels.
In the case of a minimised temporary spare
wheel (125/70 R18) inflate to a pressure of
4.2 bar as indicated on the tyre pressure la-
bel ››› Fig. 224.
Driving style
Fast cornering, heavy acceleration and hard
braking (squealing tyres) all increase tyre
wear.
Wheel balance
The wheels on new vehicles are balanced.
However, certain circumstances may lead to
imbalance (run-out), which is detected as vi-
brations in the steering wheel.
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
or if a tyre is repaired.
Incorrect wheel alignment
Incorrect running gear alignment causes ex-
cessive tyre wear, impairing the safety of the
vehicle. If you notice excessive tyre wear, you
should check wheel alignment at a SEAT Offi-
cial Service.

Wheels
WARNING
● Alw
ays adapt the tyre pressure accordingly
when the vehicle load changes.
● A tyre with low air pressure has to flex a lot
more when the
vehicle is heavily loaded or at
high speeds, therefore causing overheating
to occur. Under these conditions, the tyre
bead may be released or the tyre may burst.
Risk of accident! For the sake of the environment
Under-inflated tyres will increase fuel con-
s umption. Wear indicators
Fig. 225
Tyre tread: tread wear indicators Tread wear indicators indicate if a tyre is
w
orn. The origin

al tyres on your vehicle have
1.6 mm high “tre
ad wear indicators” running
across the tread. Depending on the manufac-
turer, there will be 6 to 8 of them spaced at
equal distances around the tyre. Markings on
the tyre sidewall (for instance the letters
“TWI” or a triangle) 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). (Different fig-
ures may apply in other countries.) WARNING
The tyres must be replaced at the latest when
the tr e

ad is worn down to the tread wear indi-
cators. Failure to follow this instruction could
result in an accident.
● Especially in difficult driving conditions
suc
h as wet or icy roads. It is important that
the tyre tread be as deep as possible and be
approximately the same on the tyres of both
the front and the rear axles.
● The scant driving safety due to insufficient
tre
ad depth is particularly evident in vehicle
handling, when there is a risk of “aquaplan-
ing” in deep puddles of water and when driv-
ing through corners, and braking is also ad-
versely affected.
● The speed has to be adapted accordingly,
otherw
ise there is a risk of losing control over
the vehicle. Changing wheels
Fig. 226
Interchanging tyres. To ensure that the wear is equal on all tyres
the wheel
s

should be changed round from
time to time according to the system
››› Fig. 226. The useful life of all the tyres will
then be about the same time.
New tyres or new wheels –
All four wheels must be fitted with tyres of
the s ame type, s

ize (rolling circumference)
and preferably the same tread pattern.
– Tyres should be replaced at least in pairs
and not indiv

idually (i.e. both front tyres or
both rear tyres together).
– Do not use tyres whose effective size ex-
ceed

s the dimensions of the factory-ap-
proved makes of tyre. »

●
Av
oid running the vehicle on tyres that are
more than 6 years old. If you have no alterna-
tive, you should drive slowly and with extra
care at all times.
● If wheel trims are fitted after the car is pur-
ch
ased, ensure that there is an adequate flow
of air for cooling the brake system. For the sake of the environment
Old tyres must be disposed of according to
the l a

ws in the country concerned. Note
● A S

EAT Service Centre should be consulted
to find out whether wheels or tyres of differ-
ent sizes to those originally fitted by SEAT
can be fitted, and to find out about the com-
binations allowed between the front axle
(axle 1) and the rear axle (axle 2).
● Never mount used tyres if you are not sure
of their
“previous history”.
● For technical reasons, it is not generally
pos
sible to use the wheels from other vehi-
cles. In some cases, this may also be true for
the same model of wheel. Wheel bolts
The wheel
bolts
ar
e matched to the rims.
When installing different wheels (for instance
alloy wheels or wheels with winter tyres) it is
important to use the correct wheel bolts with the right length and correctly shaped bolt
hea

ds. This ensures that wheels are fitted se-
curely and that the brake system functions
correctly.
The wheel bolts must be clean and turn easi-
ly.
A special adapter is required to turn the anti-
theft wheel bolts* ›››

Tyre monitoring systems Introduction WARNING
Unsuitable handling of the wheels and tyres
m a

y lead to sudden tyre pressure losses, to
tread separation or even to a blow-out.
● Check tyre pressures regularly and ensure
they ar
e maintained at the pressures indica-
ted. Tyre pressure that is too low could cause
overheating, resulting in tread detachment or
even burst tyres.
● Tyre pressure should be that indicated on
the label
when the tyres are cold at all times
››› page 303.
● Regularly check the cold inflation pressure
of the ty
res. If necessary, change the tyre
pressure of the vehicle tyres while they are
cold. ●
Re

gularly check your tyres for damage and
wear.
● Never exceed the maximum permitted
speed or lo
ads specified for the type of tyre
fitted on your vehicle. For the sake of the environment
Under-inflated tyres lead to increased fuel
c on

sumption and tyre wear. Note
● Driv in

g for the first time with new tyres at a
high speed can cause them to slightly ex-
pand, which could then produce an air pres-
sure warning.
● Only replace used tyres with those author-
ised b
y SEAT for the corresponding type vehi-
cle.
● Do not only rely on the tyre monitoring sys-
tem. R
egularly check your tyres to ensure
that the tyre pressure is correct and that the
tyres are not damaged due to puncture, cuts,
tears and impacts/dents. Remove objects
from the tyres only when they have not
pierced the tyres. 295

Winter service
Wint
er tyres –
Winter tyres must be fitted on al

l four
wheels.
– Only use winter tyres that are approved for
your

vehicle. –
Ple
ase note that the maximum permissible
speed for winter tyres may be lower than
for summer tyres.
– Also note that winter tyres are no longer ef-
fectiv

e when the tread is worn down.
– After fitting the wheels you must always
chec

k the tyre pressures. The correct tyre
pressures are listed on the sticker on the
inside of the fuel tank flap ››› page 292.
In winter road conditions winter tyres will
considerably improve vehicle handling. The
design of summer tyres (width, rubber com-
pound, tread pattern) gives less grip on ice
and snow. This applies particularly to vehi-
cles equipped with wide section tyres or with
high speed tyres (code letters H, V or Y on
the sidewall).
Only use winter tyres of the correct type ap-
proved for your vehicle. The sizes of these
tyres are specified in the vehicle's docu-
ments (e.g. EC Certificate of Conformity or
COC 1)
). The vehicle documentation varies de-
pending on the country of residence. See al-
so ››› page 293.
Winter tyres lose a great deal of their proper-
ties when the tread is worn down to a depth
of 4 mm. The performance of winter tyres is also se-
ver

ely impaired by ageing, even if the tread is
still much deeper than 4 mm.
Winter tyres are subject to the following max-
imum speed limits according to speed rating
code letter: ›››

Using winter tyres with V-rating
Pl e
ase note that the generally applicable
240 km/h (149 mph) speed for winter tyres
with the letter V is subject to technical re-
strictions; the maximum permissible speed
for your vehicle may be significantly lower .
The maximum speed limit for these tyres de-
pends directly on the maximum axle weights
for your car and on the listed weight rating of
the tyres being used.
It is best to contact a SEAT Official Service to
check the maximum speed which is permissi-
ble for the V-rated tyres fitted on your car on
the basis of this information. WARNING
Exceeding the maximum speed permitted for
the w int

er tyres fitted on your car can cause
tyre failure, resulting in a loss of control of
the vehicle – risk of accident. For the sake of the environment
Summer tyres should be fitted again as soon
a s

possible after the winter period; they give
better handling on roads which are free of
snow and ice. Summer tyres perform with
less rolling noise, tyre wear and – most im-
portant – reduce fuel consumption. 300
