Advice
Automatic car washes
Before going through a car wash, be sure to
take the usual precautions such as closing
the windows and roof. If the vehicle has spe-
cial accessories such as spoilers or a roof
rack or two-way radio aerial, etc., it is advisa-
ble 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
c lo
se 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.
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 vehicle 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 washing the car during the winter
season: water and ice in the brake system
can reduce braking effectiveness: risk of acci-
dent! CAUTION
● Do not wash the vehicle in direct sunlight –
otherwise the paint can be damaged.
● Do not use sponges, abrasive household
sponges or similar to clean insect remains.
This could damage the surface.
● Clean off stubborn dirt (insects, etc.) from
the headlights 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 wash, 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
● Before 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:
–the bonnet must be closed.
– switch the ignition on and off.
– press the windscreen wiper lever forward
briefly (windscreen washer function).
This will lock the wiper arms. For the sake of the environment
The car should only be washed in special
wash bays. These areas are prepared to pre-
vent oily water from getting into the public
drains. In some places, washing vehicles out-
side the areas intended for this purpose is
prohibited. 184

Advice
Carbon components The carbon parts on your vehicle have a pain-
ted surface. They do not need any special
care and are cleaned just like any other pain-
ted part

P aint
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

in the engine compartment Always be aware of the danger of injury and
scalding as well as the risk of accident or fire
when working in the engine compartment
(e.g. when checking and refilling fluids). Al-
ways observe the warnings listed below and
follow all general safety precautions. The en-
gine compartment of the vehicle is a poten-
tially hazardous area
››› . WARNING
● Switch the ignition off.
● Remove the ignition key.
● Apply the handbrake.
● If the vehicle has a manual gearbox, place
the lever in neutral; if it has an automatic
gearbox, place the selector lever in position
P.
● Wait for the engine to cool down.
● Keep children away from the engine com-
partment.
● Never spill liquids used for vehicle opera-
tion on the engine compartment, as these
may catch fire (e.g. the antifreeze in coolant). 198

Advice
could damage the engine
. If there is no
c
oolant in the expansion tank, do not con-
tinue driving. You should obtain professio-
nal assistance ››› .
– If there is still some coolant in the expan-
sion tank, top up to the upper mark.
– Top up with coolant until the level becomes
stable.
– Screw the cap back on correctly.
Any loss 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 cooling 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 hazard. 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, even when the ignition is
switched off, the radiator fan may start up au- tomatically, and therefore there is a risk of in-
jury.
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. Brake fluid

Checking the brake fluid level
The brake fluid level must be between the
MIN and MAX markings.
However, if the brake fluid level goes down
noticeably in a short time, or drops below the
MIN mark, there may be a leak in the brake
system. Seek specialist assistance. A warn-
ing light on the instrument panel display
monitors the brake fluid level ››› page 71.
In right-hand drive vehicles the brake fluid
reservoir is on the other side of the engine
compartment. Changing brake fluid
The regular intervals at which the brake fluid
should be replaced are listed in the Mainte-
nance Programme. We recommend you have
it replaced at a SEAT Official Service, during
an Inspection Service.
WARNING
● Brake fluid should be stored in the closed
original container in a safe place out of reach
of children. Risk of poisoning!
● If the brake fluid is left in the system for
too long and the brakes are subjected to
heavy use, vapour bubbles may form in the
brake system. This would seriously affect the
efficiency of the brakes and the safety of the
vehicle. This may cause an accident. CAUTION
Brake fluid should not come into contact with
the vehicle paintwork, as it is abrasive. Windscreen washer reservoir

it means, for example, that the tyre was man-
ufactured in the 22nd week of 2012.
But note that with some types of tyre, the ac-
tual tyre size can differ from the nominal size
marked on the tyre (for instance 205/55 R 16
91 W), and there may be significant differen-
ces in the contours of the tyres, even though
the tyres are marked with the same nominal
size designation. When replacing the tyres,
it is therefore important to make sure that
the actual size of the new tyres does not ex-
ceed the dimensions of the factory-approved
makes of tyre.
Failure to observe this requirement can af-
fect the clearance needed for the tyres. If the tyres rub against the bodywork, in certain
circumstances the tyres , suspension or
bodywork and pipes may be damaged, and
vehicle safety could be severely impaired
››› .
If you use tyres that are approved by SEAT
you can be sure that the actual tyre dimen-
sions will be correct for your vehicle. If you
decide to fit a different type of tyre, you must
obtain the appropriate manufacturer's certif-
icate from the tyre retailer to confirm that
the tyres are suitable for your vehicle. Keep
this certificate in a safe place.
Your SEAT Official Service will be able to ad-
vise you on which tyres may be fitted to your
vehicle.
It is best to have all servicing of wheels and
tyres performed by a specialised workshop.
They are familiar with the procedure and
have the necessary special tools and spare
parts as well as the proper facilities for dis-
posing of the old tyres respecting the envi-
ronment. WARNING
● It is very important to ensure that the tyres
you have chosen have adequate clearance.
When selecting replacement tyres, do not re-
ly entirely on the nominal tyre size marked on
the tyre, since the effective tyre size can dif-
fer significantly depending on the manufac-
turer. Inadequate tyre clearance can result in
damage to the tyres or the vehicle, causing a serious safety risk. Risk of accident! It may
also invalidate the vehicle's registration for
use on public roads.
●
Avoid running the vehicle on tyres that are
more than 6 years old. If you have no alterna-
tive, you should drive slowly and with extra
care at all times.
● If wheel trims are fitted after the car is pur-
chased, ensure that there is an adequate flow
of air for cooling the brake system. For the sake of the environment
Old tyres must be disposed of according to
the laws in the country concerned. Note
● Never mount used tyres if you are not sure
of their “previous history”.
● For technical reasons, it is not generally
possible to use the wheels from other vehi-
cles. In some cases, this may also be true for
the same model of wheel. Wheel bolts

Tyre monitoring systems Introduction WARNING
Unsuitable handling of the wheels and tyres
may lead to sudden tyre pressure losses, to
tread separation or even to a blow-out.
● Check tyre pressures regularly and ensure
they are maintained at the pressures indica-
ted. Tyre pressure that is too low could cause
overheating, resulting in tread detachment or
even burst tyres.
● Tyre pressure should be that indicated on
the label when the tyres are cold at all times
››› page 243.
● Re
gularly check the cold inflation pressure
of the tyres. If necessary, change the tyre
pressure of the vehicle tyres while they are
cold.
● Regularly check your tyres for damage and
wear. ●
Never exceed the maximum permitted
speed or loads specified for the type of tyre
fitted on your vehicle. For the sake of the environment
Under-inflated tyres lead to increased fuel
consumption and tyre wear. Note
● Driving for the first time with new tyres at a
high speed can cause them to slightly ex-
pand, which could then produce an air pres-
sure warning.
● Only replace used tyres with those author-
ised by SEAT for the corresponding type vehi-
cle.
● Do not only rely on the tyre monitoring sys-
tem. Regularly check your tyres to ensure
that the tyre pressure is correct and that the
tyres are not damaged due to puncture, cuts,
tears and impacts/dents. Remove objects
from the tyres only when they have not
pierced the tyres. Tyre monitor indicator warning lamp

ces. These surfaces must be clean before fit-
ting the wheel. CAUTION
When removing/fitting the wheel, the rim
may hit and damage the brake disc. For this
reason, please take care and get a second
person to assist you. Tyres with compulsory direction of
rotation
A directional tread pattern can be identified
by arrows on the sidewall that point in the di-
rection of rotation. Always observe the direc-
tion of rotation indicated when mounting the
wheel. This is important so that these tyres
can give maximum grip and avoid excessive
noise, tread wear and aquaplaning.
If, exceptionally, it is necessary to mount the
spare wheel* in the opposite direction of ro-
tation, please drive carefully, as in this case
the tyre does not have optimum conditions of
use. This is particularly important when driv-
ing on wet roads.
To benefit from the advantages of tyres with
this type of tread pattern, the defective tyre
should be replaced as soon as possible so
that all tyres again rotate in the correct direc-
tion. After changing a wheel –
On alloy wheels: replace the wheel bolt
caps.
– On plate wheels: replace the wheel hubcap
››› page 217.
– Put the tools and jack back in the luggage
compartment.
– If the replaced wheel does not fit in the
spare wheel housing, store it safely in the
luggage compartment ››› page 114.
– Check the tyre pressure of the newly moun-
ted tyre as soon as possible.
– In vehicles fitted with a tyre pressure indi-
cator, adjust the pressure and store the
reading in the radio/ Easy Connect system*

– The wheel bolts should be tightened to 120
Nm. Check the torque as soon as possible
with a torque wrench. Meanwhile, drive
carefully.
– Have the flat tyre replaced as quickly as
possible. Tyre repair
