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
››› page 183.
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

Advice
The retract function may not operate properly
in very dirty belts. Make sure that the inertia
reel seat belts are completely dry before al-
lowing them to retract. CAUTION
● Do not remove the seat belts from the vehi-
cle to clean them.
● Do not use chemical cleaning agents on the
seat belts, as this can damage the webbing.
Ensure that the seat belts do not come into
contact with corrosive fluids.
● If you find any damage to the belt webbing,
belt fittings, the belt retractor or the buckle,
the belt in question must be replaced by a
specialised workshop. Intelligent technology
Electro-mechanical steering Electro-mechanical power steering assists
the driver when steering.
Electro-mechanical power steering adapts
electronically to the speed of the car, torque
and t
urnin
g angle.
If the power steering should fail at any time
or the engine is switched off (for instance
when being towed), the car can still be
steered. However, more effort than normal
will be required to turn the steering wheel.
Driver warning lamps and messages  (in red) Faulty steering! To park the vehicle
If the warning lamp remains on and the driver
indication appears, the power steering could
be faulty.
Do not continue driving. Seek specialist as-
s

istance.
 (in yellow) Steering: System fault! You
may continue driving.
If the warning lamp comes on, the steering
could react with more difficultly or more sen-
sitivity than normal. In addition, when driving
in a straight line the steering wheel may be
off-centre. Drive slowly to a specialised workshop and
have the fault repaired.

Depending on the vehicle equipment, the
progressive steering can adapt steering hard-
ness to the current driving situation. The
power steering only works when the engine
is running.

sportier, more direct and noticeably more dy-
namic driving sensation.
Four-wheel drive 3
Valid for vehicles: with four-wheel drive
On all-wheel drive models, the engine power
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 143, Brak-
ing and stability systems .
The all-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 ››› .
Winter tyres
Thanks to all-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 to
giv e ev
en better braking response. Snow chains
On roads where snow chains are mandatory,
this also applies to cars with four-wheel drive
››› page 216.
Chan

ging 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 210.
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
● Even with all-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
still has good acceleration in these condi-
tions. Risk of accident!
● On wet roads bear in mind that the front
wheels may start to “aquaplane” and lose contact with the road if the car is driven too
fast. If this should happen, there will be no
sudden increase in engine speed to warn the
driver, as occurs with a front-wheel drive car.
For this reason you should always choose a
driving speed suitable for the road condi-
tions. Risk of accident!
Power Management
This system helps to ensure reliable
starting The power management controls the distribu-
tion of electrical energy and thus helps to en-
sure that there is always enough power avail-
able to start the engine.
If a vehicle with a conventional electrical sys-
tem is left parked for a long time, the battery
will gradually lose its charge because certain
electrical devices, such as the electronic
gearbox lock continues to draw current even
when the ignition is off. In some cases there
may not be enough power available to start
the engine.
Your vehicle is equipped with an intelligent
power management system to control the
distribution of electrical energy. This signifi-
cantly improves reliability when starting the
engine, and also prolongs the useful life of
the battery.

Wheels and tyres General notes –
When driving with new tyres, be especially
car
eful during the first 500 km (300 miles).
– If you have to drive over a kerb or similar
obstacle, drive very slowly and as near as
possible at a right angle to the obstacle.
– Check from time to time if the tyres are
damaged (punctures, cuts, cracks or
dents). Remove any foreign objects embed-
ded in the treads.
– Damaged wheels and tyres must be re-
placed immediately.
– Keep grease, oil and fuel off the tyres.
– Replace any missing valve caps as soon as
possible.
– Mark the wheels before taking them off so
that they rotate in the same direction when
put back.
– When removed, the wheels or tyres should
be stored in a cool, dry and preferably dark
place.
New tyres
New tyres do not give maximum grip straight
a w

ay and should therefore be “run in” by driving carefully and at moderate speeds for
about the first 500 km (300 miles). This will
also increase the useful life of the tyres.
The tread depth of new tyres may
v
ary, ac-
cording to the type and make of tyre and the
tread pattern.
Concealed damage
Damage to tyres and rims is often not readily
visible. If you notice unusual vibration
or the
car pulling to one side, this may indicate that
one of the tyres is damaged. Reduce speed
immediately if there is any reason to suspect
that damage may have occurred. Inspect the
tyres for damage. If no external damage is
visible, drive slowly and carefully to the near-
est specialised workshop and have the car
inspected.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the di-
rection of rotation on single drive tyres. Al-
ways note the direction of rotation indicated
when mounting the wheel. This guarantees
optimum grip and helps to avoid aquaplan-
ing, excessive noise and wear.
Retrofitting Accessories
If you wish to change or fit wheels, rims or
wheel trims, we recommend that you consult
with a SEAT Official Service centre for advice
regarding current techniques. Useful life of tyres Correct inflation pressures and sensible driv-
ing habits will increase the useful life of your
tyres.
– Check tyre pressure at least once a month,
and also prior to any long trip.
– The tyre pressure should only be checked
when the tyres are cold. Do not reduce the
pressure of warm tyres.
– Adjust tyre pressure to the load being car-
ried by the vehicle.
– In vehicles with a tyre pressure indicator,
save the pressure of modified tyres
››› page 212 , ››
›
page 208.
– Avoid fast cornering and hard acceleration.
– Inspect the tyres for irregular wear from
time to time.
The useful life of your tyres depends on the
following factors:
Tyre pressure
Tyre pressure values are indicated on the
sticker on the inside of the fuel tank flap.
Insufficient or excessive pressure greatly re-
duces the useful life of the tyres and adverse-
ly affects vehicle performance and ride. Cor-
rect inflation pressures are very important,
especially at high speeds.
208

Wheels
Depending on the vehicle, tyre pressure can
be adjusted (“comfort” tyre pressure) to in-
crease driving comfort. When driving with
comfort tyre pressure fuel consumption may
increase slightly.
The tyre pressure must be adjusted according
to the load the vehicle is carrying. If the vehi-
cle is going to carry the maximum load, the
tyre pressure should be increased to maxi-
mum value indicated on the sticker on the in-
side of the fuel tank flap.
Do not forget the spare wheel when checking
the tyre pressures: Keep this spare wheel in-
flated to the highest pressure required for the
road wheels.
In the case of a minimised temporary spare
wheel (125/70 R16 or 125/70 R18) inflate to
a pressure of 4.2 bar as indicated on the tyre
pressure label on the fuel tank flap.
Driving style
Fast cornering, heavy acceleration and hard
braking (squealing tyres) all increase tyre
wear.
Wheel balance
The wheels on new vehicles are balanced.
However, certain circumstances may lead to
imbalance (run-out), which is detected as vi-
brations in the steering wheel. Unbalanced wheels should be rebalanced, as
they otherwise cause excessive wear on
steering, suspension and tyres. A wheel must
also be rebalanced when a new tyre is fitted
or if a tyre is repaired.
Incorrect wheel alignment
Incorrect wheel alignment causes excessive
tyre wear, impairing the safety of the vehicle.
If you notice excessive tyre wear, you should
check wheel alignment at a SEAT Official
Service.
WARNING
● Always adapt the tyre pressure accordingly
when the vehicle load changes.
● A tyre with low air pressure has to flex a lot
more when the vehicle is heavily loaded or at
high speeds, therefore causing overheating
to occur. Under these conditions, the tyre
bead may be released or the tyre may burst.
Risk of accident! For the sake of the environment
Under-inflated tyres will increase fuel con-
sumption. Wear indicators
Fig. 177
Tyre tread: tread wear indicators Tread wear indicators indicate if a tyre is
worn.
The original tyres on your vehicle have
1.6 mm high “tread wear indicators” running
across the tread. Depending on the manufac-
turer, there will be 6 to 8 of them spaced at
equal distances around the tyre. Markings on
the tyre sidewall (for instance the letters
“TWI” or a triangle) indicate the positions of
the tread wear indicators.
The minimum tread depth required by law is
1.6 mm (measured in the tread grooves next
to the tread wear indicators). (Different fig-
ures may apply in other countries.)

WARNING
The tyres must be replaced at the latest when
the tread is worn down to the tread wear indi-
cators. Failure to follow this instruction could
result in an accident.
● Especially in difficult driving conditions
such as wet or icy roads. It is important that
the tyre tread be as deep as possible and be
approximately the same on the tyres of both
the front and the rear axles.
● The scant driving safety due to insufficient
tread depth is particularly evident in vehicle
handling, when there is a risk of “aquaplan-
ing” in deep puddles of water and when driv-
ing through corners, and braking is also ad-
versely affected.
● The speed has to be adapted accordingly,
otherwise there is a risk of losing control over
the vehicle. Changing wheels
Fig. 178
Interchanging tyres. To ensure that the wear is equal on all tyres
the wheels should be changed round from
time to time according to the system
››› Fig. 178 . The useful life of all the tyres will
then be about the s
ame time.
Replacing wheels and tyres –
All four wheels must be fitted with tyres of
the same type, size (rolling circumference)
and preferably the same tread pattern.
– Tyres should be replaced at least in pairs
and not individually (i.e. both front tyres or
both rear tyres together). –
Do not use tyres whose effective size ex-
ceeds the dimensions of the factory-ap-
proved makes of tyre.
– If you wish to fit the vehicle with rims or
tyres different to those installed in manu-
facture, it is advisable to consult a SEAT Of-
ficial Service before purchasing them.
The ty r

es and wheel rims are an essential
part of the vehicle's design. The tyres and
rims approved by SEAT are specially matched
to the characteristics of the vehicle and make
a major contribution to good roadholding
and safe handling ››› .
The sizes of the rims and tyres approved for
your vehicle are listed in the vehicle docu-
mentation (e.g. EC Certificate of Conformity or
COC document 1)
). The vehicle documentation
varies depending on the country of resi-
dence.
Note for Italy: A SEAT Service Centre should
be c on

sulted whether different sized wheels
or tyres to those originally fitted by SEAT may
be fitted, as well as the combinations al-
lowed between the front axle (axle 1) and
back axle (axle 2).
A knowledge of tyre designations makes it
easier to choose the correct tyres. The follow-
ing wording can be read on the sides of the
tyre: 1)
COC = certificate of conformity.

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

control of the vehicle and a serious or fatal
accident.
●
If the warning lamp  lights up, stop im-
mediately and check the tyres.
● If the tyres are inflated at different pres-
sures or if a tyre pressure is too low, this will
increase tyre wear, negatively affecting vehi-
cle stability and increasing braking distan-
ces.
● If tyres are inflated at different pressures or
a tyre pressure is too low, a tyre may be dam-
aged and burst resulting in a loss of control
of the vehicle.
● The driver is responsible for ensuring that
all of the vehicle tyres are correctly inflated
to the right pressure. The recommended tyre
pressure is indicated on the label
››› page 243.
● The ty r
e monitoring system can only oper-
ate correctly if all of the tyres are inflated to
the correct pressure when cold.
● Driving with tyres at the wrong pressure
can damage them and result in an accident.
Ensure that the tyre pressures of all the tyres
correspond to the vehicle load.
● Before starting a journey, always inflate
tyres to the correct pressure.
● Tyres with insufficient pressure are subjec-
ted to more flexing. Due to this, the tyre
could become excessively hot, causing tread
separation and also tyre blow-out.
● With an overloaded vehicle at high speed,
the tyres can overheat and burst resulting in
a loss of vehicle control. ●
Tyre pressures which are too high or too
low reduce the useful life of the tyre, affect-
ing vehicle performance.
● If a tyre has not been punctured and it does
not have to be changed immediately, drive to
the nearest specialised workshop at a moder-
ate speed and have the tyre checked and in-
flated to the correct pressure. WARNING
Observe the safety warnings ››› in Control
and warning lamps on page 71. Note
● If excessively low tyre pressure is detected
with the ignition on, an audible warning will
sound. In the event that there is a fault in the
system, an audible warning will sound.
● Driving on dirt tracks for a long period of
time or driving in a sporty style can tempora-
rily deactivate the TPMS. The control lamp
shows a fault, but disappears when road con-
ditions or the driving style change. Tyre monitoring indicator
