Care and maintenance
A SEAT Official Service and specialised work-
shop w i
l
l be able to inform you about options
for installing and operating radio transmitters
with a higher transmitting power.
Mobile radio transmitters
Commercial mobile telephones or radio
equipment might interfere with the electron-
ics of your vehicle and cause malfunctions.
This may be due to:
● No external aerial.
● External aerial incorrectly installed.
● Transmitting power more than 10 W.
You mus
t, therefore, do not operate portable
mobile telephones or radio equipment inside
the vehicle without a properly installed exter-
nal aerial ››› .
Pl e
a

se note also that the maximum range of
the equipment can only be achieved with an
external aerial.
Business equipment
Retrofit installation of business or private
equipment in the vehicle is permitted, provi-
ded the equipment cannot interfere with the
driver's immediate control of the vehicle and
that any such equipment carries the  mark.
Any retrofit equipment that could influence
the driver's control of the vehicle must have a
type approval for your vehicle and must carry
the e mark. WARNING
Mobile telephones or radio equipment which
is oper

ated inside the vehicle without a prop-
erly installed external aerial can create exces-
sive magnetic fields that could cause a health
hazard. Note
● The pos t

erior fitting of electric and elec-
tronic equipment in this vehicle affects its li-
cence and could lead to the withdrawal of the
vehicle registration document under certain
circumstances.
● Please use the mobile telephone/radio op-
erating in
structions. Care and cleaning
Gener a
l

information Regular and careful care helps to
maint
ain
the
value of the vehicle. This may also be one
of the requirements for upholding any war-
ranty claims in the event of corrosion or paint
defects.
SEAT Official Services and specialist retailers
carry stocks of suitable car care materials.
Please follow the instructions for use on the
packaging. WARNING
● Cle

aning products and other materials used
for car care can be damaging to your health if
misused.
● Always keep care products in a safe place,
out of the r
each of children. Failure to comply
could result in poisoning. For the sake of the environment
● If po s

sible, use environmentally friendly
products.
● The remains of car care products should not
be dispo
sed of with ordinary household
waste. Vehicle exterior care

Automatic car washes
B ef
or
e going through a car wash, be sure to
take the usual precautions such as closing
the windows and roof. If the vehicle has spe-
cial accessories such as spoilers or a roof
rack, it is advisable to consult the car wash
tunnel operator.
It is best to use a car wash without revolving
bristles if possible.
Washing the vehicle with a high pressure
cleaner
When washing the vehicle with a high-pres-
sure cleaner, always follow the operating in-
structions for the equipment. This applies
particularly to the operating pressure and the
spraying distance. Do not hold the nozzle too
close to soft materials such as rubber hoses
or seals. The same applies for the parking aid
sensors*, which are located in the rear
and/or front bumper.
Do not use a nozzle that sprays the water out
in a direct stream or one that has a rotating
jet for forcing off dirt.
Factory-fitted adhesive sheets
The following indications should be taken in-
to account to avoid damaging adhesive
sheets:
● Do not use high pressure cleaners. ●
Do not use s crapers to remove ice or snow
from the sheets.
● Do not polish the adhesive sheets.
● Do not use dirty cloths or sponges.
● It is preferable to wash them with a soft
spong
e and gentle neutral soap.
Washing the car by hand
When washing the car by hand, use plenty of
water to soften the dirt first, and rinse off as
well as possible.
Then clean the vehicle with a soft sponge,
glove or brush using only slight pressure.
You should start on the roof and work down.
Special car soap should only be used for very
persistent dirt.
Rinse the sponge or glove thoroughly and of-
ten.
Wheels, sills and similar should be cleaned
last. Use a second sponge for this. WARNING
● The v ehic

le should only be washed with the
ignition switched off. Failure to follow this in-
struction could result in an accident.
● Do not clean the underside of chassis, the
inside of
wheel arches or wheel trims without
protecting your hands and arms. You may cut
yourself on sharp-edged metal parts. Other-
wise, there is a risk of sustaining cuts. ●
When wa shin

g the car during the winter
season: water and ice in the brake system
can reduce braking effectiveness: risk of acci-
dent! CAUTION
● Do not wa

sh the vehicle in direct sunlight –
otherwise the paint can be damaged.
● Do not use sponges, abrasive household
spong
es or similar to clean insect remains.
This could damage the surface.
● Clean off stubborn dirt (insects, etc.) from
the headlight
s at regular intervals, for in-
stance when filling the fuel tank. The head-
lights should only be washed with water, do
not wipe them with a dry cloth or sponge. It
is best to use soapy water.
● Never wash tyres with a jet that sprays the
water out
in a direct stream. This could dam-
age the tyres even if the spray is kept at a
distance and only used for a very short time.
● Before washing the vehicle in an automatic
car wa
sh, please make sure to retract the ex-
terior mirrors to prevent them from being
damaged. Electrically retractable exterior
mirrors must not be folded in or out by hand,
always use the electrical power control. CAUTION
● Bef or

e washing the vehicle in an automatic
car wash, please proceed as follows to lock
the wiper arms so that they are not moved to-
wards the top of the windscreen: 286

Care and maintenance
WARNING
Please note when cleaning the wheels that
wat er
, ice and road salt can impair the effec-
tiveness of the brakes; this can cause an acci-
dent. Exhaust pipe
It is important to remove road salt and brake
dus
t

by washing the wheels at regular inter-
vals, otherwise the exhaust tail pipe material
could be damaged. To remove impurities, do
not use rim, paint or chrome cleaners or oth-
er abrasive products. Clean the exhaust tail
pipes with cleaning products that are suita-
ble for stainless steel.
SEAT Official Services carry stocks of cleaning
products that have been tested and ap-
proved for use on your vehicle.
Caring for the vehicle interior Scr een f

or the radio/Easy Connect*
and control panel* The display can be cleaned with a soft cloth
and a pr
of
e

ssionally available “LCD cleaner”.
Moisten the cloth with a small amount of the
cleaning fluid. The Easy Connect control panel* should first
be cle

aned with a brush so that no dirt goes
into the device or between the keys and
housing. Next, we recommend cleaning the
Easy Connect control panel* using a cloth
dampened with water and washing-up liquid. CAUTION
● To av oid s

cratching the screen, do not wipe
the display with a dry cloth.
● To avoid damage, ensure that no liquid
goes
into the Easy Connect control panel*. Plastic and leatherette parts
Plastic parts and leatherette can be cleaned
w
ith a d
amp c

loth. If this is not sufficient,
plastic parts and leatherette should only be
treated with a special solvent-free plastic
cleaner.
Textile covers and trim parts Textile covers and trim parts (e.g. seats, door
trim) shou
l
d be c

leaned regularly with a vac-
uum cleaner. This will remove surface dirt
which could otherwise be rubbed into the
textile material during use. Do not use steam
cleaners, as the steam could carry the dirt
deeper into the textile material. Normal cleaning
We rec

ommend that you use a soft sponge or
a commercially available lint-free, micro-fibre
cloth for normal cleaning. Only use brushes
on floor coverings and mats, as other textile
surfaces could become damaged.
In the case of normal surface dirt you can use
a foam cleaner. Use a sponge to spread the
foam on the textile surface and to work it into
the material lightly. However, make sure that
the textile material does not become soaking
wet. Then dab off the foam with a dry and ab-
sorbent cloth (e.g. a micro-fibre cloth) and
vacuum off any residue once the surface is
completely dry.
Cleaning stains
Treat drink stains (such as coffee or fruit
juice, etc.) with a cleaning solution for deli-
cate fabrics. This solution should be applied
with a sponge. If the stains are difficult to re-
move, a washing paste can be applied direct-
ly onto the stain and worked into the fabric.
The surface will then have to be wiped with
clear water to remove any residue left by the
paste. To do so, use a damp cloth or sponge
and then dab the stain with an absorbent
cloth.
Remove chocolate or make-up stains with a
cleaning paste (for e.g., soft soap). Then re-
move the soap with water (wet sponge). »

● Never spill liquids used for vehicle opera-
tion on the engine comp
artment, as these
may catch fire (e.g. the antifreeze in coolant).
● Take care not to cause short circuits in the
electrica
l system, especially when working
on the battery.
● If working inside the engine compartment,
remember that, ev
en 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-
sul
ating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pans
ion tank when the engine is hot. The
cooling system is under pressure.
● Protect face, hands and arms by covering
the cap with a l
arge, thick rag to protect
against escaping coolant and steam.
● If it is necessary to work in the engine com-
partment
while the engine is running, the ro-
tating components (for example, poly-V belt, alternator, radiator fan) and the high voltage
ignition sys
t

em are an additional hazard.
● Observe the following additional warnings
if work
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 is p

ut 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

Advice
However, if the brake fluid level goes down
notic e
ab
ly in a short time, or drops below the
MIN mark, there may be a leak in the brake
system. Seek specialist assistance. A warn-
ing light on the instrument panel display
monitors the brake fluid level ››› page 119.
In right-hand drive vehicles the brake fluid
reservoir is on the other side of the engine
compartment.
Changing brake fluid
The regular intervals at which the brake fluid
should be replaced are listed in the Mainte-
nance Programme. We recommend you have
it replaced at a SEAT Official Service, during
an Inspection Service. WARNING
● Brak e fluid shou

ld be stored in the closed
original container in a safe place out of reach
of children. Risk of poisoning!
● If the brake fluid is left in the system for
too long and the br
akes are subjected to
heavy use, vapour bubbles may form in the
brake system. This would seriously affect the
efficiency of the brakes and the safety of the
vehicle. This may cause an accident. CAUTION
Brake fluid should not come into contact with
the v ehic

acity
The reservoir holds approximately 3 litres in
versions without headlight washer and 5 li-
tres in versions with headlight washer. WARNING
If the water from the windscreen washer does
not c ont

ain enough anti-freeze, it may freeze
on the windscreen and rear window, reducing
forward and rear visibility.
● In winter, ensure the windscreen washer
contain
s enough anti-freeze.
● In cold conditions, you should not use the
winds
creen wiper system unless you have
warmed the windscreen with the ventilation
system. The antifreeze could freeze on the
windscreen and reduce visibility. WARNING
Never mix an unsuitable antifreeze or other
simi l

ar additives with the windscreen washer
water. A greasy layer may be formed on the
windscreen which will impair visibility.
● Use clean water with a window cleaner rec-
ommended by
SEAT.
● If necessary, add a suitable antifreeze to
the water in the r
eservoir.304

Checking and refilling levels
CAUTION
● Do not mi x
cleaning products recommen-
ded by SEAT with other products. This could
lead to flocculation and may block the wind-
screen washer jets.
● When topping up service fluids, make abso-
lutely c
ertain that you fill the fluids into the
correct reservoirs. Using the wrong fluids
could cause serious malfunctions and engine
damage!
● Not having windscreen wiper fluid reduces
vis
ibility through the windscreen, and leads
to loss of visibility in headlights in models

nning 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-
cha
sed, 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 aw

s in the country concerned. Note
● A S EA

T 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 “pr
evious history”.
● For technical reasons, it is not generally
poss
ible to use the wheels from other vehi-
cles. In some cases, this may also be true for
the same model of wheel. Wheel bolts

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

s. 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
ma y

lead to sudden tyre pressure losses, to
tread separation or even to a blow-out.
● Check tyre pressures regularly and ensure
they are m
aintained 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 ty
res are cold at all times
››› page 319.
● Regularly check the cold inflation pressure
of the tyr
es. If necessary, change the tyre
pressure of the vehicle tyres while they are
cold. ●
Re gu

larly check your tyres for damage and
wear.
● Never exceed the maximum permitted
speed or loa
ds 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 s

umption and tyre wear. Note
● Driv ing f

or 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 by
SEAT for the corresponding type vehi-
cle.
● Do not only rely on the tyre monitoring sys-
tem. Re
gularly 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. 311

s or at a pressure that is too low then a
tyre may be damaged resulting in a loss of control of the vehicle and a serious or fatal
acc
ident

.
● If the warning lamp  lights up
, stop im-
mediately and check the tyres.
● If the tyres are inflated at different pres-
sure
s or if a tyre pressure is too low, this will
increase tyre wear, negatively affecting vehi-
cle stability and increasing braking distan-
ces.
● If tyres are inflated at different pressures or
a tyre pr
essure is too low, a tyre may be dam-
aged and burst resulting in a loss of control
of the vehicle.
● The driver is responsible for ensuring that
all
of the vehicle tyres are correctly inflated
to the right pressure. The recommended tyre
pressure is indicated on the label
››› page 319.
● The tyre monitoring system can only oper-
ate corr
ectly if all of the tyres are inflated to
the correct pressure when cold.
● Driving with tyres at the wrong pressure
can dam
age them and result in an accident.
Ensure that the tyre pressures of all the tyres
correspond to the vehicle load.
● Before starting a journey, always inflate
tyre
s to the correct pressure.
● Tyres with insufficient pressure are subjec-
ted to mor
e flexing. Due to this, the tyre
could become excessively hot, causing tread
separation and also tyre blow-out.
● With an overloaded vehicle at high speed,
the tyre
s can overheat and burst resulting in
a loss of vehicle control. ●
Ty r

e pressures which are too high or too
low reduce the useful life of the tyre, affect-
ing vehicle performance.
● If a tyre has not been punctured and it does
not hav
e to be changed immediately, drive to
the nearest specialised workshop at a moder-
ate speed and have the tyre checked and in-
flated to the correct pressure. WARNING
Observe the safety warnings ›
