Advice
consumables should be changed at a speci-
ali sed w
ork
shop. Technical services are per-
manently informed of any modifications. WARNING
The incorrect use or handling of fluids or con-
sum ab

les may result in accident, serious in-
jury, burns or intoxication.
● Therefore, fluids must always be stored
closed in their origin
al container.
● Never store fluids in empty food containers
or bottles
as other people may accidentally
drink the fluid.
● Keep all fluids and consumables out of
reac
h of children.
● Read and observe the information and
warning
s given on the fluid containers.
● Only work in the open air or in well-ventila-
ted z
ones, when using products which give
off harmful vapours.
● Never use fuel, turpentine, engine oil, ace-
tone or any
other volatile liquid in the main-
tenance of the vehicle. These are toxic and
highly flammable. They could lead to fire or
explosions! CAUTION
● Only u

se appropriate fluids. Do not confuse
fluids as this can cause serious malfunctions
or engine damage.
● Accessories and other components moun-
ted in front
of the air inlet reduce the cooling effect of the coolant. If the engine is running
under gr
e

at strain in high outside tempera-
tures, it could overheat. For the sake of the environment
Leaking fluids could pollute the environment.
C o l

lect any spilt fluids in suitable containers
and dispose of them in accordance with legis-
lation and with respect for the environment. Repairs and technical changes
When performing repairs and technical mod-
ific
ation
s,

SEAT's directives must be ob-
served! ››› Unauthorised modifications to the electronic
c
omponents
or sof

tware in the vehicle may
cause malfunctions. Due to the way the elec-
tronic components are linked together in net-
works, other indirect systems may be affec-
ted by the faults. This may significantly affect
the vehicle's performance, increase compo-
nent wear and could mean that the vehicle
registration documents are no longer valid.
Your SEAT Official Service cannot be held lia-
ble for any damage caused by technical mod-
ifications or repairs performed incorrectly.
The SEAT Official Service does not accept lia-
bility for damage resulting from technical
modifications or repairs performed incorrect- ly; neither is the SEAT warranty valid in these
case

s.
SEAT recommends you have any technical
modifications or repairs performed at a SEAT
Official Service and that you use genuine
SEAT spare parts ®
.
Vehicles with special accessories and equip-
ment
The manufacturers of additional equipment
guarantee that the equipment complies with
applicable laws and regulations with respect
to the environment, in particular Directives
2000/53/CE and 2003/11/CE. The first direc-
tive governs the disposal of end-of-life vehi-
cles while the second refers to the restric-
tions on the marketing and use of certain
dangerous substances and preparations.
The vehicle owner should keep the documen-
tation for the additional equipment safely
and hand it over to the scrap yard at the end
of the vehicle's service life. This ensures that
any additional equipment mounted in end-of-
life vehicles is correctly disposed of with re-
spect for the environment. WARNING
Repairs or modifications which are not per-
formed c orr

ectly may result in damage or er-
rors in the vehicle operation, affecting the ef-
fectiveness of the driver assist systems. This
could result in serious accident. 160

this p

urpose, to prevent dirty water which
may be contaminated by oil, grease or fuel,
from entering the drains. In some places,
even washing it outside the planned areas is
banned. For the sake of the environment
Where possible, always use products which
re s

pect the environment. For the sake of the environment
The remains of car care products should not
be dis po

sed of with ordinary household waste. Observe information provided by the
manuf
act

urer. Washing the vehicle
The longer substances such as insects, bird
drop
pin

gs, 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. The vehicle undercarriage should
also be thoroughly washed at regular inter-
vals.
Automatic car washes
Always observe the instructions provided at
the automatic car wash. The standard pre-
cautionary measures prior to entering the car
wash should be taken to avoid damage to
the vehicle (close all windows, fold in exterior
mirrors). If the vehicle is fitted with additional
components (spoiler, roof-rack, aerial, etc.),
check with the car wash supervisor whether
these can enter the car wash ››› .
The v
ehic

le paintwork is so durable that the
vehicle can normally be washed without
problems in an automatic car wash tunnel.
However, wear and damage to the paintwork
will depend on the type of car wash used. »

Water box
The water box is in the engine compartment,
between the windscreen and the engine, and
beneath a perforated cover. Air is taken in
through the water box from outside to the ve-
hicle interior via the heating and air condi-
tioner.
Leaves and other loose objects should be
regularly cleaned away from the water box ei-
ther by hand or with a vacuum. WARNING
When working on the engine or in the engine
comp ar

tment, there is a risk of injury, burns,
accident or fire.
● Before starting work, please ensure you are
famili
ar with the required procedure and the
safety precautions ››› page 184.
● SEAT recommends getting a specialised
workshop t
o do these jobs. CAUTION
If water is manually poured into the water box
(e.g. u s

Introduction The dye from many items of modern clothing
(e.g. d
ark

jeans) is not always colour-fast.
Seat upholstery (material and leather), espe-
cially when light-coloured, may visibly discol-
our if the dye comes out of clothing (even
when used correctly). This is not an uphols-
tery defect but indicates that the dye in the
item of clothing is not sufficiently colour-fast. WARNING
Car-care products may be toxic and hazard-
ous. If c

ar care products are not suitable or
are used inappropriately, this could result in
accident, serious injury, burns or intoxica-
tion.

To treat and maintain your seat upholstery,
keep the f
o

llowing in mind ››› :
● Before entering the vehicle, close any Vel-
cr o f

asteners that might snag on the uphols-
tery or trim fabric. Any open Velcro fasteners
may damage the trim or upholstery fabrics.
● To prevent damage, avoid direct contact
between sharp dec
orative objects and the
upholstery and trim fabrics. Decorative ob-
jects include zips, rivets and rhinestones on
clothing and belts.
● From time to time, clean the dust that gath-
ers in the per

forations, folds and seams so
that the surfaces of the seats are not dam-
aged by its abrasive effect.
● Make sure clothes are colour-fast to avoid
them running and s
taining the upholstery.
This is especially important if the upholstery
is light in colour. CAUTION
If the instructions for upholstery and trim
car e ar

e not followed, they may deteriorate
and discolour. Note
SEAT recommends you take the vehicle to a
Spec i

alised workshop to treat any stains on
the upholstery caused by the discolouration
of clothing. Cleaning padding and textile covers
Normal cleaning
● Before applying cleaning products, please
re a

d the instructions for handling and the
warnings shown on the container.
● The upholstery, textile covers, and carpet
should be r
egularly vacuumed (with vacuum
brush).
● We recommend that you use a soft sponge
or lint-free, mic
ro-fibre cloth for normal clean-
ing ››› .
Gener al
s

uperficial dirt on upholstery and
textile covers can be cleaned with a normal
foam cleaning product.
If the upholstery and the material trims are
very dirty, we recommend you have them
cleaned by a specialist cleaning form.
Cleaning stains
It may be necessary to clean the whole sur-
face and not only the stain itself. Especially if
the surface has been dirtied through normal
use. Otherwise, the stained area may be-
come lighter than the rest of the surface after
treatment. »

back in the same place. Certificate of safety
A certific

ate of safety on the door strut states
that all the safety standards and regulations
established by the national traffic authorities
responsible for road safety were met at the
time of manufacture. It may also give the
month and year of manufacture, together
with the chassis number.
Warning of high voltage label
There is a label close to the bonnet lock
which warns of high voltage in the vehicle's
electrical system.

Using your vehicle in other countries
and continents The vehicle is manufactured at the factory for
u
se in a p
ar

ticular country in accordance with
the national legislation in force at the time of
manufacture.
If the vehicle is sold in another country or
used in another country for an extended peri-
od of time, the applicable legislation of that
country should be observed. It may be necessary to fit or remove certain
pieces

of equipment or to deactivate certain
functions. Service work may also be affected.
This is particularly true if the vehicle is used
in a different climate for an extended period
of time.
As there are different types of frequency
bands around the world, you may find that
the radio system or the Portable Navigation
System (supplied by SEAT) supplied at the
factory does not work in another country. CAUTION
● SEA T doe

s not accept liability for any dam-
age to the vehicle due to the use of a lower
quality fuel, an inadequate service or the
non-availability of genuine spare parts.
● SEAT does not accept liability if the vehicle
does not
comply in part or in full with the le-
gal requirements of other countries or conti-
nents. Radio and antenna reception

P etr
o

l types are categorised according to
their octane number (e.g. 91, 95, 98 or 99
RON (RON = “Research Octane Number”).
You may use petrol with a high octane num-
ber than the one recommended for your en-
gine. However, this has no advantage in
terms of fuel consumption and engine power.
SEAT recommends refuelling with a low sul-
phur content or sulphur-free petrol to reduce
fuel consumption for petrol engines. Petrol additives
The quality of the f

uel 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

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 178

Checking and refilling levels
metal additives. Using them may damage the
engine!
● On ly
use fuel with an octane rating that is
in line with the norm EN 228, otherw
ise sig-
nificant damage could be caused to the en-
gine and fuel system. Furthermore, it could
lead to a loss of performance with the conse-
quent engine fault.
● The use of unsuitable petrol additives could
seriously
damage the engine and the catalyt-
ic converter.
● If, in exceptional circumstances, petrol with
a lower oct
ane rating to that recommended is
used, only use moderate engine speeds and a
light throttle. Avoid using full throttle and
overloading the engine. Otherwise engine
damage may occur. Fill up with fuel of a suita-
ble octane rating as soon as possible.
● Just filling one full tank of leaded fuel or
with other meta
l additives would seriously
impair the efficiency of the catalytic convert-
er and could damage it. Natural gas
Natural gas, in addition to others, can be in
li
quid f
orm.
Li

quefied 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.
Theref

ore, vehicles with a natural gas engine
must only be refuelled using compressed
natural gas ››› .
Nat ur
a

l 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
one 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.
Natural gas and safety
If you can smell gas or suspect that there is a
leak ››› :
● Stop the vehicle immediately. ●
Sw it
c

h the ignition off.
● Open the doors to appropriately ventilate
the vehic
le.
● Immediately extinguish cigarettes.
● Move away from the vehicle or switch off
obj
ects that may cause sparks or a fire.
● If you continue to smell gas, do not contin-
ue driving!
● Seek

specialist assistance. Have the fault
repair
ed. WARNING
Failure to act when you can smell gas in the
vehic l

e 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
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 natural gas system must be subject to
re gu

lar inspections at a specialised work-
shop in accordance with the Maintenance
Programme. 179

Refuelling or handling fuel carelessly can
cau se an e

xplosion or fire resulting in serious
burns and injuries.
● Always make sure that you correctly close
the fuel c
ap to avoid evaporation and fuel
spillage.
● Fuels are highly explosive and inflammable
subs
tances that can cause serious burns and
injuries.
● Fuel could leak out or be spilt if the engine
is not
switched off or if the filler fuel nozzle is
not fully inserted into the tank filler neck
when refuelling. This could lead to a fire, ex-
plosion and severe injuries.
● When refuelling, turn off the engine and
turn off the ignition f
or safety reasons.
● Always turn off mobile telephones, radio
appar
atus and other radio wave emitting
equipment before refuelling. Electromagnetic
waves could cause sparks and lead to a fire.
● Never enter the vehicle while refuelling. If it
is ab
solutely necessary to enter, close the
door and touch a metal surface before touch- ing the filler nozzle again. This will prevent
the gener
ation of

static electricity. Sparks
could cause a fire when refuelling.
● Never handle fuel close to flames, sparks or
obj
ects with slow combustion (e.g. ciga-
rettes).
● Avoid static electricity and electro-magnet-
ic ra
diation when refuelling.
● Observe the safety regulations of the serv-
ice st
ation.
● Never spill fuel on the vehicle or in the lug-
gage c
ompartment. WARNING
For safety reasons, SEAT does not recommend
carr y

ing a spare fuel canister in the vehicle.
Fuel could be spilled and catch fire, above all
in case of an accident and this applies to a
full container as well as empty containers.
This could lead to explosions, fires and inju-
ries.
● Observe the following if you exceptionally
have t
o carry fuel in a canister:
– Never place a fuel container, to fill it, in-
side the vehicle or on the vehicle, for ex-
ample, in the luggage compartment. Fill-
ing in these circumstances could create
an electrostatic charge and spark that
could ignite fuel fumes.
– Always place the canister on the ground
to fill it. –
Inser t

the fuel nozzle into the neck of the
canister as far as possible.
– If you are using a metal fuel canister, the
nozzle must always touch the canister
while it is being filled to avoid static elec-
tricity.
– Follow the legal requirements for the use,
storage and transport of spare fuel canis- ters.
– Insure that the fuel container complies
with manufacturing standards, for exam-
ple, ANSI or ASTM F852-86. CAUTION
● Alw a

ys remove any fuel spilled anywhere
on the vehicle to avoid damage to the wheel
housing, the tyre and vehicle paintwork.
● Refuelling a petrol engine with diesel can
cause seriou
s engine and fuel system dam-
age; the resulting malfunctions are not cov-
ered by the SEAT warranty. If you refuel with
the wrong type of fuel, never start the engine.
This applies to even the smallest amount of
the wrong fuel. Seek specialist assistance.
With the engine running, the composition of
the wrong fuel could significantly damage the
fuel system and the engine itself. For the sake of the environment
Fuels can contaminate the environment. Col-
