Advice
Automatic car washes
B ef
or
e going through a car wash, be sure to
take the usual precautions (closing the win-
dows, roof and rear-view mirrors). If the vehi-
cle has special accessories such as spoilers
or a roof rack or two-way radio aerial, etc., 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 to the parking aid
sensors*, which are located in the rear bump-
er.
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: 258

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). »

A spirit-based cleaner can be used to remove
gr e
a
se, oil, lipstick or ball point pen. Then
dab the dissolved grease or colour particles
off with an absorbent cloth or similar. You
may also have to treat the stain once more
using washing paste and water.
If the covers or textile trim panels are badly
soiled we recommend that you have them
cleaned by a professional cleaning company
with a shampoo and spray. Note
Open Velcro fasteners on clothes can damage
the seat upho

lstery. Make sure they are
closed. Natural leather
General information
Our r
an
g

e of leathers is large. The main type
used is particularly nappa in various forms,
that is, leather with a smooth surface in dif-
ferent colours.
The amount of dye used determines the ap-
pearance and properties of leather. If the
leather is left in a more natural state, it re-
tains its typical natural napped appearance
and confers excellent all-weather properties
to the seats. Fine veins, healed scars, insect
bites, wrinkles and a subtle variation in shad- ing remain visible; these are the characteris-
tic fe

atures of genuine natural leather.
Natural napped leather does not have a pro-
tective surface coating of dye. It is therefore
somewhat more prone to damage. This
should be borne in mind if children or pets
often travel in the car, or if there are other
factors that could lead to damage.
Types of leather with a coloured surface coat-
ing are likely to be more resistant to damage.
This has a great advantage for day-to-day
use. However, this means that the typical
natural characteristics of the surface are less
apparent, though this does not affect quality.
Cleaning and care
Due to the natural properties of the specially
selected hides employed, the finished leath-
er has a certain sensitivity to grease and dirt,
etc. so a degree of care is required in every-
day use and when looking after the leather.
Dark clothing (especially if damp or incorrect-
ly dyed) may stain leather upholstery on the
seats. Dust and grit in the pores and seams
can scratch and damage the surface. There-
fore leather should be cleaned at regular in-
tervals, depending on the actual amount of
use. When they have been in use for a certain
time, your car seats will acquire a typical and
unmistakable patina. This is characteristic for
leather as a natural product and is a sign of
genuine quality. To maintain the value of natural leather you
should not
e the following points: CAUTION
● Av oid e

xposing leather to direct sunlight
for long periods, otherwise it may tend to
lose some of its colour. If the car is left for a
prolonged period in the bright sun, it is best
to cover the leather.
● Sharp-edged objects on clothing, such as
belts, z
ip fasteners, rivets or similar, can also
leave permanent scratches and rough marks
on the surface of the leather. Note
● Use a s uit

able impregnating cream with ul-
tra-violet protection at regular intervals and
after cleaning. The cream nourishes and
moisturises the leather, keeps it supple and
able to breathe. A protective film will also
form.
● Clean the leather every 2 to 3 months and
remov
e fresh dirt as soon as possible.
● Remove stains from fresh ball-pen and oth-
er inks, lips
tick, shoe cream and similar
stains as soon as possible.
● Preserve the colour of the leather. A special
colour
ed cream will renew the colour of the
leather when required and will eliminate dif-
ferences in colour. 262

Care and maintenance
Cleaning and care of leather uphols-
t er
y Natural leather requires an extra degree of at-
tention and c
ar
e.
Normal cleaning
– Moisten a cotton or woollen cloth with wa-
ter and wipe o

ver the leather surfaces.
More stubborn dirt
– More stubborn dirt can be removed using a
mil d so

ap solution (pure liquid soap: two
tablespoons dissolved in one litre of wa-
ter).
– Do not let the water soak through the leath-
er or penetrate int

o the seams.
– Then wipe off with a soft, dry cloth.
Remov
al of stains
– Remove fresh water
-based stains such as
coffee, tea, juices, blood etc. with an ab-
sorbent cloth or kitchen roll, or use the
cleaning agent from the care set for dried-
on stains.
– Remove fresh grea
se-based stains that
have not penetrated the surface such as
butter, mayonnaise, chocolate, etc. with an
absorbent cloth or kitchen roll or with the
cleaning agent from the care set. –
Tre
at fat-based, dried-in stains with grease-
dissolving spray.
– Treat less common stains on le
ather, such
as ball-pen and other inks, felt-tip pens,
nail polish, dispersion paint, shoe cream
etc. with a special leather stain remover.
Leather maintenance
– The leather should be treated regularly
(about twic

e a year) with a special leather-
care product.
– Apply these products very sparingly.
– Then wipe off with a soft cloth.
Should
you have questions regarding the
care and cleaning of the leather upholstery in
your vehicle, we recommend that you contact
your SEAT Official Service. Our representa-
tives will be happy to advise you and tell you
about the product range for leather conserva-
tion, for example:
● Cleaning and care set.
● Coloured leather-care cream.
● Stain remover for ball-pen inks, shoe cream
etc.
● Gr

ease dissolving spray.
● New products and further developments CAUTION
On no account use solvents (such as petrol,
turpentine), w ax

polish, shoe cream or simi-
lar materials. Cleaning Alcantara upholstery
Removing dust and dirt
– Moisten a cloth just a lit
tle and wipe down
the seat covers.
Removing stains – Moisten a cloth with lukewarm water or di-
luted whit

e spirits.
– Dab at the stain. Start at the outside and
work in

wards.
– Dry the clean area with a soft cloth.
Do not use l
eather cleaning products on Al-
cantara seat covers.
You may use a suitable soap on dust and dirt.
Dust and grit in the pores and seams can
scratch and damage the surface. If the car is
left standing in the sun for long periods, Al-
cantara leather should be protected against
direct sunlight to prevent it from fading. How-
ever, slight colour variations will arise in nor-
mal use. »

n
leaded petrol
We recommend you use super 95 octane pet-
rol. If this is not available: normal 91 octane
petrol, with a slight decrease in power.
Super unleaded petrol with a minimum of 95
octanes
You should use super petrol with a minimum
of 95 octanes.
If super is not available, in an emergency you
may refuel with normal 91 octane petrol. In
this case only use moderate engine speeds
and a light throttle. Refuel with super as soon
as possible.
Super unleaded 98 octane or super 95 oc-
tane unleaded petrol
We recommend you use super plus 98 octane
petrol. If this is not available: super 95 oc-
tane petrol, with a slight decrease in power.
If super is not available, in an emergency you
may refuel with normal 91 octane petrol. In
this case only use moderate engine speeds
and a light throttle. Refuel with super as soon
as possible.
Petrol additives
The quality of the fuel influences the behav-
iour, power and service life of the engine.
This is why the petrol you use should carry
suitable additives already included by the petrol industry, free of metals. These addi-
tives
will help to prevent corrosion, keep the
fuel system clean and prevent deposits from
building up in the engine.
If good-quality petrol with metal-free addi-
tives is not available or engine problems
arise, the necessary additives must be added
when refuelling ››› .
Not al
l

petrol additives have been shown to
be effective. The use of unsuitable petrol ad-
ditives may cause significant damage to the
engine and the catalytic converter. Metal ad-
ditives should never be used. Metal additives
may also be contained in petrol additives for
improving anti-detonation ratings or octane
ratings ››› .
S EA
T r

ecommends “genuine Volkswagen
Group Fuel Additives for petrol engines”.
These additives can be bought at SEAT deal-
ers, where information on how to use them
can also be obtained. CAUTION
● Do not r ef

uel if the filler indicates that the
fuel contains metal. LRP ( lead replacement
petrol) fuels contain high concentrations of
metal additives. Using them may damage the
engine!
● Never refuel with fuels containing a large
proportion of
ethanol (for example, E50, E85).
This could damage the fuel system. ●
Jus t

filling one full tank of leaded fuel or
fuel containing other metal additives would
seriously impair the efficiency of the catalytic
converter.
● Only use fuel additives that have been ap-
prov
ed by SEAT. Octane boosting or anti-
knock additives may contain metal additives
that could seriously damage the engine or
the catalytic converter. These additives must not be used.
● High engine speed and full throttle can
damag
e the engine when using petrol with an
octane rating lower than the correct grade for
the engine. Note
● You m a

y use petrol with a high octane num-
ber than the one recommended for your en-
gine.
● In those countries where unleaded petrol is
not avai
lable, you may refuel with a fuel with
a low lead content. Diesel fuel

le.
– Screw the cap back on correctly.
Any lo
ss of coolant fluid normally indicates a
leak in the cooling system. Take the vehicle
straight to a specialised workshop to have
the cooling system examined. If there are no
leaks in the engine cooling system, a loss of
coolant can only occur if the coolant boils
and is forced out of the system as a result of
overheating. WARNING
● The coo lin

g system is under pressure. Do
not unscrew the cap on the coolant expan-
sion tank when the engine is hot: risk of
burns!
● The antifreeze and coolant fluid can be a
health h
azard. Therefore, the antifreeze
should be stored in the original container in a
safe place out of reach of children. Failure to
comply could result in poisoning.
● 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
. WARNING
If there is not enough anti-freeze in the cool-
ant sys

tem, the engine may fail leading to se-
rious damage.
● Please make sure that the percentage of
additiv
e is correct with respect to the lowest
expected ambient temperature in the zone in
which the vehicle is to be used.
● When the outside temperature is very low,
the cool
ant could freeze and the vehicle
would be immobilised. In this case, the heat-
ing would not work either and inadequately
dressed passengers could die of cold. CAUTION
Do not top up the expansion tank with cool-
ant fluid if it

is empty! Air could enter the
cooling system. In this case, stop driving.
Seek specialist assistance. Otherwise, there
is a risk of engine damage. CAUTION
The original additives should never be mixed
with c oo

lants which are not approved by
SEAT. Otherwise, you run the risk of causing
severe damage to the engine and the engine
cooling system.
● If the fluid in the expansion tank is not pur-
ple b
