Care and maintenance
A SEAT Official Service and specialised work-
shop will be able to inform you about options
for installing and operating radio transmitters
with a higher
transmitting power.
Mo
bile 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 must, therefore, do not operate portable
mobile telephones or radio equipment inside
the vehicle without a properly installed exter-
nal aerial ››› .
Please note also that the maximum range of
the equipment can only be achieved with an
external aerial.
B u

siness 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 operated inside the vehicle without a prop-
erly installed external aerial can create exces-
sive magnetic fields that could cause a health
hazard. Note
● The posterior 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 instructions. Care and cleaning
General information Regular and careful care helps to
maintain
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
● Cleaning 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 reach of children. Failure to comply
could result in poisoning. For the sake of the environment
● If possible, use environmentally friendly
products.
● The remains of car care products should not
be disposed of with ordinary household
waste. Vehicle exterior care
Washing the vehicle The longer substances such as insects, bird
droppings, resinous tree sap, road dirt, in-
dustrial deposits, tar, soot or road salt and
other aggressive materials remain on the ve-
hicle, the more damage they do to the paint-
work. High temperatures (for instance due to
strong sunlight) further intensify the corro-
sive effect.
After the period when salt is put on the roads
it is important to have the underside of the
vehicle washed thoroughly.

Care and maintenance
Camera sensors and lenses ●
Use a small brush to remove snow and a
de-icer spray to remove ice.
● Clean the sensors with a solvent-free prod-
uct and a soft, dry cloth.
● Moisten the camera lens using a standard
alcohol-based glass cleaning agent and
clean the lens with a dry cloth. In the active
lane assist*, the area in front of the lens is
norm al
ly cleaned with the windscreen wash-
er. CAUTION
● When you clean the vehicle with a pressure
washer:
–Stay a suitable distance from the sensors
on the front and rear bumpers.
– Do not clean the camera lenses or sur-
rounding area with the pressure washer.
● Never use warm or hot water to remove
snow and ice from the reverse camera lens,
as it could crack the lens.
● Never use abrasive cleaning agents on the
lens. Care and polishing
Care
Waxing protects the paintwork. It is time to
apply a
coat of good wax when water no lon- ger forms droplets
and rolls off the clean
paintwork.
Even if a wax solution is used regularly in the
vehicle washing tunnel, it is advisable to pro-
tect the paint with a hard wax coating at least
twice a year.
In the summer, you will find it is much easier
to remove dead insects (which accumulate
on the bumper and the front of the bonnet) if
the car has been treated with care products
recently .
P o

lishing
Polishing is only necessary if the paint has
lost its shine, and the gloss cannot be
brought back by putting on wax.
If the polish does not contain wax, a wax
product should be applied after polishing. CAUTION
● Do not use polishes and hard wax on pain-
ted parts with a matt finish or on plastic
parts.
● Do not apply paint polishes to the side trim
that runs around the panoramic roof and ends
on the windscreen. However, it can be treated
with hard wax. Trims
In respect for the environment, the silver-
plated trims on the body are made of pure
aluminium (they do not contain chrome).
Dirt or marks on the trim mouldings should
be removed with a cleaning product with a
neutr
a

l PH (do not use a chrome cleaner).
Body polish is also unsuitable for use on trim
mouldings. The intensive cleaning fluids of-
ten used before the car goes into a car wash
may contain alkaline substances, which can
cause dull or milky patches when they dry
out.
SEAT Official Services carry stocks of cleaning
products which have been tested for use on
your vehicle and are not harmful to the envi-
ronment.
Plastic parts Plastic parts are cleaned with a power wash-
er. If this is not sufficient, plastic parts
should only be treated with a special solvent-
free
plastic cleaning agent
. Do not
u
se paint-
work cleaners, polishes or wax on plastic
parts.

damage Minor damage to the paint, such as scratches
or stone chips, should be touched up without
delay
before the metal starts to corrode. Suit-
ab l

e touch-up brushes or sprays for your car
can be obtained from a SEAT Official Service.
The number of the original paint finish on the
vehicle is given on the data sticker
››› page 241
.
If corrosion is already visible it must be thor-
oughly removed by a specialised workshop.
Windows Clear vision is an essential safety factor.
The windscreen must not be cleaned with in-
sect remover or wax, otherwise the wind-
screen wipers will not function properly (jud-
dering).
Traces of rubber, oil, grease or silicone can
be removed with a
window cleaning solution
or a silicone remover. Wax residue can only be remo
ved with a special cleaner. Your SEAT
Official Service will be able to provide you
with more detailed information.
The windows should also be cleaned on the
inside at regular intervals.
Use a separate cloth or chamois to dry the
windows. Cloths used for waxing and polish-
ing contain residues that will cause smears
on the glass. WARNING
Do not use water-repellent coatings on the
windscreen. In bad visibility conditions (e.g.
in the rain, dark or with a low sun), these
coatings may cause dazzle: risk of accident!
Such coatings can also cause the windscreen
wiper blades to make noise. CAUTION
● Remove snow and ice from windows and ex-
terior mirrors with a plastic scraper only. To
avoid scratches caused by dirt on the glass,
the scraper should only be pushed in one di-
rection and not moved to and fro.
● The heating element for the rear window is
located on the inner side of the window. To
avoid damaging them, do not apply stickers
to these heating elements.
● Never use warm or hot water to remove
snow and ice from windows and mirrors. This
could cause the glass to crack! Wheels
The wheels require regular attention to pre-
serve their appearance. It is important to re-
move road salt and brake dust by washing
the wheels at regular intervals, otherwise the
finish will be impaired.
After washing, the wheels should only be
cleaned with an "acid-free" cleaning agent
for alloy wheels. This is available from SEAT
Official Services and specialist retailers. Nev-
er leave the cleaning agent on the rims for
any longer than specified in the instructions
before rinsing it off. If the wheel cleaner fluid
contains acid it can attack the surfaces of the
wheel bolts.
Car polish or other abrasive agents should
not be used for maintaining the rims. If the
protective coating is damaged, e.g. by flying
stones, the damaged area should be re-
paired immediately.
WARNING
Please note when cleaning the wheels that
water, ice and road salt can impair the effec-
tiveness of the brakes; this can cause an acci-
dent. Exhaust tail pipe

intervals, otherwise the exhaust tail pipe ma-
terial could be damaged. To remove impuri-
ties, do not use rim, paint or chrome cleaners
or other abrasive products. Clean the exhaust
tail pipes with cleaning products that are
suitable for stainless steel.
SEAT Official Services carry stocks of cleaning
products that have been tested and ap-
proved for use on your vehicle.
Care of the vehicle interior
Radio display/Easy Connect* and
control panel* The display can be cleaned with a soft cloth
and a professionally available “LCD cleaner”.
Moisten the cloth with a small amount of the
cleaning fluid.
The Easy Connect control panel* should first
be cleaned 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 avoid scratching 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
with a damp cloth. If this is not sufficient,
plastic parts and leatherette should only be
treated with a special solvent-free plastic
c l
eaner.
Te
xtile covers and trim parts Textile covers and trim parts (e.g. seats, door
trim) should be cleaned 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 recommend 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) andvacuum 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
grease, 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.

Checking and refilling levels
WARNING
Natural gas is a highly explosive, easily flam-
mable substance. Incorrect handling of the
natural gas can cause accidents serious
burns and other injuries.
● Before refuelling with natural gas, engage
the filling mouth correctly. If you can smell
gas, stop refuelling immediately. WARNING
The vehicle is not prepared to use liquefied
natural 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 filling nozzles of natural gas pumps
can differ in the way they are operated. If you
do not know, ask a qualified employee at the
petrol station to do the refuelling.
● Noises heard when refuelling are normal
and do not indicate the presence of a fault in
the system.
● The vehicle natural gas system is prepared
both for refuelling with a small compressor
(slow refuel) and a large compressor (fast re-
fuel) in natural gas service stations. Fuel
Types of petrol The correct grade of petrol is listed inside the
fuel tank 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
St and
ard 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 f o

llowing titles appear on the corre-
sponding adhesive on the fuel tank flap:
Super unleaded 95 octane or normal 91
octane unleaded 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
octane 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 all 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 ››› .

Checking and refilling levels
Liquefied natural gas (LNG) is the result of
heavy cooling of natural gas. Therefore its
volume is considerably reduced compared
with compressed natural gas (CNG). In vehi-
cles with a natural gas engine, liquefied nat-
ural gas cannot be directly refilled, as the gas
would expand excessively in the vehicle gas
tank.
Therefore, vehicles with a natural gas engine
must only be refuelled using compressed
natural gas ››› .
Natural gas quality and consumption
Natural gas is divided into the groups H and
L depending on its quality.
Gas type H has a superior heating power and
inferior nitrogen and carbon dioxide content
than type L. The higher the heating power of
the natural gas, the lower the consumption
will be.
However, the heating power and the propor-
tion of nitrogen and carbon dioxide can fluc-
tuate within the quality groups. Therefore, ve-
hicle consumption can also vary when using
a single type of gas only.
The engine management automatically
adapts to the natural gas used according to
its quality. Therefore, different quality gases
can be mixed in the tank, without the need
for comprehensive draining before applying a
different quality gas. Updated information relating to natural gas
quality is displayed on the instrument panel
››› page 72 .
Nat ur
al gas and safety
If you can smell gas or suspect that there is a
leak ››› :
● Stop the vehicle immediately.
● Switch the ignition off.
● Open the doors to appropriately ventilate
the vehicle.
● Extinguish cigarettes immediately.
● Move away from the vehicle or switch off
objects that may cause sparks or a fire.
● If you continue to smell gas, do not contin-
ue driving!
● Seek specialist assistance. Have the fault
repaired. WARNING
Failure to act when you can smell gas in the
vehicle or when refuelling can cause serious
injuries.
● Carry out the necessary operations.
● Leave the danger zone.
● If necessary, warn the emergency services. WARNING
The vehicle is not prepared to use liquefied
natural 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
Have the natural gas system checked regular-
ly by a specialised workshop, according to
the Maintenance Programme. 197

Advice
Engine oil General notes The engine comes with a special, multi-grade
oil that 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 201, Oil properties .
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 service 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-
tervals.
● Only in exceptional circumstances, if the
engine oil level is too low ››› page 201 and
LongLife oil is not available, it is permitted to
top up (once) with oil for fixed service inter-
vals › ››
page 201 (up to a maximum of 0.5 li-
tres).
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 201,
Oil properties . In this case, your vehicle must
be serviced after a fixed interval of 1
year/15,000 km (10,000 miles)(whatever comes first)
››› Booklet Maintenance Pro-
gramme.
● In ex

ceptional circumstances, if the engine
oil level is too low ››› page 201 and you can-
not o

btain 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 201 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).
