Advice
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 tail 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 Ra dio di

splay/Easy Connect* and con-
trol 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).

Advice
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.

ault repaired.
 (in yellow) Steering lock:
fault! Go to an Official Service
The electronic steering lock is malfunction-
ing.
Go to a specialised workshop as soon as
possible and have the fault repaired. WARNING
Take it immediately to a specialised work-
shop and hav e the f

ault repaired: risk of acci-
dent! Note
If the lamp  (in red) or el se
 (in yellow)
lights up briefly, you may continue driving. Progressive steering
Depending on the vehicle equipment, the
pr
ogr
e

ssive steering can adapt steering hard-
ness to the current driving situation. The
power steering only works when the engine
is running.
In city traffic you do not need to turn so much
on parking, manoeuvring or in very tight
turns.
On the road or on the motorway, progressive
steering transmits, for example, in bends, a sportier, more direct and noticeably more dy-
namic driv

ing sensation.
Four-wheel drive 3 Valid for vehicles: with four-wheel drive


› ›

› table on page 2
On four-wheel drive models, the engine pow-
er is distributed to all four wheels
General notes
On four-wheel drive vehicles, the engine
power is distributed to all four wheels. The
distribution of power is controlled automati-
cally according to your driving style and the
road conditions. Also see ›››
page 176, Brak-
ing and stability systems .
The four-wheel drive is specially designed to
complement the superior engine power. This
combination gives the vehicle exceptional
handling and performance capabilities, both
on normal roads and in more difficult condi-
tions, such as snow and ice. Even so (or per-
haps especially for this reason), it is impor-
tant to observe certain safety points ››› .
W int
er ty

res
Thanks to four-wheel drive, your vehicle will
have plenty of traction in winter conditions,
even with the standard tyres. Nevertheless,
we still recommend that winter tyres or all- season tyres be fitted on all
four wheels t
o
give even better braking response.
Snow chains
On roads where snow chains are mandatory,
this also applies to cars with four-wheel drive
›››  page 60.
Changing tyres
On vehicles with four-wheel drive, all four
tyres must have the same rolling circumfer-
ence. Also avoid using tyres with varying
tread depths ››› page 273.
Off-roader?
Your SEAT is not an off-road vehicle: it does
not have enough ground clearance to be
used as such. It is therefore best to avoid
rough tracks and uneven terrain as much as
possible. WARNING
● Ev en w

ith four-wheel drive, you should al-
ways adjust your speed to suit the condi-
tions. Do not let the extra safety features
tempt you into taking any risks when driving.
Risk of accident!
● The braking capability of your vehicle is
limited by
the tyres' grip. It is therefore no
different from a car without four-wheel drive.
So do not be tempted to drive too fast on firm
or slippery roads just because the vehicle 254

ral gas pump carefully.
The vehicle is not prepared for refuelling with
liquefied natural gas (LNG) ››› . Before refu-
el lin
g w

ith natural gas, make sure you add
the appropriate type of fuel ››› page 258.
Opening the fuel tank cap
The natural gas filler mouth is behind the fuel
tank cap, next to the petrol filler mouth.
● Unlock the vehicle with the key or with the

Special feature: if the ambient temperature is
very high, the natural gas pump protection
against overheating disconnects this auto-
matically.
● Remove the plug from the gas filler mouth
›››
Fig. 239 1 .
● Connect the pump filling nozzle to the gas
fi l
l

er mouth.
● The fuel tank will be full when the p
ump
compressor automatically cuts the supply. ●
If y
ou wish to finish refuelling in advance,
press the button on the pump to stop the
flow.
Closing the fuel tank cap
● Check that the gas filler mouth retainer 2 is not trapped with the filler nozzle. If neces-
s
ar
y

, place it in the filler mouth again.
● Insert the plug in the filler mouth.
● Close the tank flap. Make sure you hear it
click
into place. WARNING
Natural gas is a highly explosive, easily flam-
mab l

e substance. Incorrect handling of the
natural gas can cause accidents serious
burns and other injuries.
● Before refuelling with natural gas, engage
the fillin
g mouth correctly. If you can smell
gas, stop refuelling immediately. WARNING
The vehicle is not prepared to use liquefied
nat ur

al gas (LNG), and this fuel must not be
added under any circumstances. Liquefied
natural gas can cause the natural gas tank to
explode, resulting in serious injury. Note
● The fil lin

g nozzles of natural gas pumps
can differ in the way they are operated. If you do not know, ask a qualified employee at the
petro
l

station to do the refuelling.
● Noises heard when refuelling are normal
and do not indicat
e the presence of a fault in
the system.
● The vehicle natural gas system is prepared
both for ref
uelling with a small compressor
(slow refuel) and a large compressor (fast re-
fuel) in natural gas service stations. Fuel
Ty
pe

s of petrol The correct grade of petrol is listed inside the
f
uel
t

ank flap.
The vehicle is equipped with a catalytic con-
verter and must only be run on unleaded pet-
rol. The petrol must comply with European
Standard EN 228 or German standard DIN
51626-1 and must be unleaded. You can re-
fuel with a maximum ethanol proportion of
10 % (E10). The types of petrol are differenti-
ated by their octane rating (RON).
The following titles appear on the corre-
sponding adhesive on the fuel tank flap:

Checking and refilling levels
Super unleaded 95 octane or normal 91 oc-
t ane u
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
Please note the information on the inside of
the f
uel

Advice
Engine oil Gener a
l
notesThe engine comes with a special, multi-grade
oil
th

at can be used all year round.
Because the use of high-quality oil is essen-
tial for the correct operation of the engine
and its long useful life, when topping up or
changing oil, use only those oils that comply
with VW standards.
The specifications (VW standards) set out in
the following page should appear on the con-
tainer of the service oil; when the container
displays the specific standards for petrol and
diesel engines together, it means that the oil
can be used for both types of engines.
We recommend that the oil change indicated
in the Maintenance Programme, be per-
formed by a technical service or specialised
workshop.
The correct oil specifications for your engine
are listed in the ›››
 page 51, Oil proper-
ties.
Service intervals
Service intervals can be flexible (LongLife
service) or fixed (dependent on time/dis-
tance travelled).
If the PR code that appears on the back of the
Maintenance Programme booklet is PR QI6, this means that your vehicle has the LongLife
serv
ic

e programmed. If it lists the codes QI1,
QI2, QI3, QI4 or QI7, the interval service is
dependent on time/distance travelled.
Flexible service intervals (LongLife service
intervals*)
Special oils and processes have been devel-
oped which, depending on the characteris-
tics and individual driving profiles, enable
the extension of the oil change service (Long-
Life service intervals).
Because this oil is essential for extending the
service intervals, it must only be used ob-
serving the following indications:
● Avoid mixing it with oil for fixed service in-
terv
als.
● Only in exceptional circumstances, if the
engine oil
level is too low ››› page 265 and
LongLife oil is not available, it is permitted to
top up (once) with oil for fixed service inter-
vals ›››
 page 51 (up to a maximum of 0.5
litres).
Fixed service intervals*
If your vehicle does not have the “LongLife
service interval” or it has been disabled (by
request), you may use oils for fixed service
intervals, which also appear in
›››  page 51, Oil properties
. In this case,
your vehicle must be serviced after a fixed in-
terval of 1 year/15,000 km (10,000 miles) (whatever comes first)
›››
Booklet Mainte-
nance Programme.
● In exceptional circumstances, if the engine
oil l
evel is too low ››› page 265 and you can-
not obtain the oil specified for your vehicle,
you can add a small quantity of oil conform-
ing to the specification ACEA A2 or ACEA A3
(petrol engines) or ACEA B3 or ACEA B4 (die-
sel engines) (up to 0.5 l).
Vehicles with diesel particulate filter*
The Maintenance Programme states whether
your vehicle is fitted with a diesel particulate
filter.
Only VW 507 00 engine oil, with reduced ash
formation, may be used in diesel engines
equipped with particulate filter. Using other
types of oil will cause a higher soot concen-
tration and reduce the life of the DPF. There-
fore:
● Avoid mixing this oil with other engine oils.
● Only in exceptional circumstances, if the
engine oil
level is too low ››› page 265 and
you cannot obtain the oil specified for your
vehicle, you can use a small quantity of oil
(once) conforming to the VW 506 00,
VW 506 01, VW 505 00, VW 505 01 or
ACEA B3/ACEA B4 specification. (up to 0.5 l).
