ain the

value of the vehicle. This may
also be one of the requirements for acknowl- edging warranty claims in the event of body-
work c

orrosion or paint defects.
Products suitable for the care of your vehicle
are available at any technical service. 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.
● Car care products must always be stored in
the original
container which should be kept
closed.
● Observe information provided by the manu-
factur
er.
● To prevent confusion, never store car care
products
in empty food cans, bottles or other
containers.
● Keep all care products out of reach of chil-
dren.
● Harmfu

l vapours may be produced when us-
ing car c
are products. Therefore, care prod-
ucts should only be used in well-ventilated
spaces or in the open air.
● Never use fuel, turpentine, engine oil, ace-
tone or any
other volatile liquid to wash,
clean or care for the vehicle. These are toxic
and highly flammable. WARNING
Inappropriate care and cleaning of vehicle
component s

may effect the vehicle safety
equipment, increasing the risk of severe in-
jury.
● Vehicle components should only be
cle
aned and maintained in accordance with
the manufacturer's instructions.
● Only use approved or recommended care
products. CAUTION
Cleaning products which contain solvents will
dam ag

e the material. For the sake of the environment
Only wash the vehicle in areas allocated for
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

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. SEAT recommends the use of car washes
without bru

shes.
To remove traces of wax on windows and to
prevent wiper blades from scratching, please
observe the following ››› page 172, Cleaning
windows and exterior mirrors .
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.
Start at the roof and work downwards. Spe-
cial car shampoo 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
Sharp components on the vehicle may cause
injury .
● Pr

otect arms and hands from sharp edges
when cle
aning the vehicle undercarriage or
the interior of the wheel hubs. WARNING
After the vehicle has been washed, the brak-
ing eff ect

will be reduced (and the braking
distance increased) due to moisture (and ice
in winter) on the brakes.
● “Dry the brakes and remove ice” by braking
caref
ully. Ensure that you are not endanger-
ing other road-users or breaking traffic regu-
lations in the process. CAUTION
● The wat er t

emperature should not exceed
+60 °C (+140 °F).
● To avoid damage to the paintwork, do not
wash the
vehicle in full sun.
● Do not use rough sponges or similar which
coul
d damage the surface to clean away the
traces of insects.
● Never wipe the headlights with a dry cloth
or spong
e, always moisten first. It is best to
use soapy water.
● Washing the vehicle in low temperatures:
When washin
g the vehicle with a hose, do
not direct water into the lock cylinders or the
gaps around the doors or roof. Locks and
seals could freeze! CAUTION
To avoid any risk of damage to the vehicle,

v

ing wax residue
Automatic car washes and certain car care
products may leave wax deposits on the win-
dows. These deposits can only be removed
with a special product or cleaning cloths. If
wax deposits are left on the windscreen and
the rear window, the blades can scratch the
glass. SEAT recommends you wipe the wax
deposits off the windscreen and the rear win-
dow with a soft cloth each time after you
have washed the vehicle.
A window cleaning detergent which helps to
dissolve the wax may be added to the wind-
screen washer fluid to prevent the wiper
blades from scratching the windscreen.
Please ensure you add the cleaning product
in the correct proportions. Products for re-
moving grease do not eliminate the wax de-
posits ››› .
S pec
i

al cleaning products or window cloths
are available at any technical service. To re-
move wax deposits, SEAT recommends the
following products:
● For the hottest time of the year: the window
cle
aner for summer use G 052 184 A1. Pro- portion 1:100 (1 part detergent, 100 parts
water) in the w

indscreen washer reservoir.
● All year round: the window clean-
er G 052 164 A2; proportion 1:2 in w
ind-
screen washer bottle (1 part concentrate, 2
parts water) in winter, up to -18 ℃ (-0.4°F), or
1:4, during the rest of the year.
● Window cloths G 052 522 A1 for all win-
dows
and exterior mirrors.
Removing snow
Use a small brush to remove snow from the
windows and exterior mirrors.
Removing ice
If possible, use a de-icing spray to remove
ice. If you use an ice scraper, push it in one
direction only without swinging it. If you pull
the scraper backwards, the dirt may scratch
the window. WARNING
Dirty or misted windows reduce visibility in
al l

directions and increase the risk of acci-
dent and serious injury.
● Do not drive unless you have good visibility
through al
l windows!
● Remove ice and snow from the windows
and demist
inside and out. CAUTION
● Never mi x

our cleaning products with other
products not recommended by SEAT in the
windscreen washer reservoir. This could lead
to flocculation and may block the windscreen
washer jets.
● Do not use hot or warm water to remove ice
or snow fr
om the windows and exterior mir-
rors. The glass could crack!
● The heating element for the rear window is
located on the inner s
ide of the window. Do
not stick adhesive labels over the heating el-
ements and never clean the inside of the rear
window with corrosive or acid products or
other similar chemical cleaning products. Caring for and polishing the vehicle

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 186.
● 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

ing a high pressure cleaning appli-
ance), this could cause significant damage to
the vehicle. For the sake of the environment
Only wash the engine compartment in areas
al loc

ated for this purpose, to prevent dirty
water which may be contaminated by oil,
grease or fuel, from entering the drains. In
some places, even washing this compartment
outside planned areas for this purpose is

a low lead content. Natural gas
Natural gas
Natur
al

gas can be compressed or in liquid
form, addition to others.
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 ››› .
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 nitrog

en 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.
Natural 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 v
ehic

le.
● Extinguish cigarettes immediately.
● 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

Due to the problems linked with disposing of
used oil and the need for suitable tools and
special knowledge, always visit a specialised
workshop to have the engine oil and filter
changed. SEAT recommends taking your car
in for technical service.
Detailed information on the service intervals
is shown in the Maintenance Programme.
Engine oil additives make new oil darker after
the engine has been running for a short peri-
od. This is normal and does not mean more
frequent oil changes are required. WARNING
Only change the engine oil yourself if you
hav e the s

pecialist knowledge required!
● Before opening the bonnet, read and ob-
serve the w
arnings ››› page 186.
● Wait for the engine to cool down. Hot oil
may
cause burn injuries.
● Wear eye protection to avoid injuries, such
as ac
