The windscreen wiper blades are supplied as
standard with a layer of graphite. This layer is
responsible for ensuring that the wipe is si-
lent. If the graphite layer is damaged, the
noise of the water as it is wiped across the
windscreen will be louder.
Check the condition of the wiper blades regu-
larly. If the wipers scrape across the glass
they should be changed if they are damaged,
or cleaned if they are dirty ››› .
Dam ag
ed w

iper blades should be replaced
immediately. These are available from quali-
fied workshops. WARNING
Worn or dirty wiper blades reduce visibility
and incr e

ase the risk of accident and serious
injury.
● Always replace damaged or worn blades or
bla
des which do not clean the windscreen
correctly. CAUTION
● Damag ed or dir

ty windscreen wipers could
scratch the glass.
● If products containing solvents, rough
spong
es or sharp objects are used to clean
the blades, the graphite layer will be dam-
aged.
● Never use fuel, nail varnish remover, paint
thinner or simil
ar products to clean the win-
dows. CAUTION
● To pr ev

ent damage to the bonnet and the
wiper arms, only leave them in the service
position.
● Before driving, always lower the wiper
arms. Note
If wax deposits, other cleaning products from
the autom atic

car wash, or other care prod-
ucts, are left on the windscreen and the rear
window, the blades can scratch the glass. Re- move wax deposits with a special product or

When towing or tow starting, respect the le-
gal requirements.
For technical reasons, it is not possible to
tow a vehicle if the battery is flat.
In general, the vehicle should not be started
by towing. Jump-starting is much more pref-
erable ›››

For technical reasons, the following vehicles
can not be tow started:
● Vehicles with an automatic gearbox.
● If the vehicle battery is flat, it is possible
that the en

gine control unit does not operate
correctly.
However, if your vehicle must absolutely be
tow-started (manual gearbox):
● Put it into second or third gear.
● Keep the clutch pressed down.

St eerin
g
Intr

oduction The power steering* is not hydraulic but elec-
tromec
h

anical. The advantage of this steer-
ing system is that it disposes of hydraulic
tubes, hydraulic oil, the pump, filter and oth-
er components. The electromechanical sys-
tem saves fuel. While a hydraulic system re-
quires oil pressure to be maintained, electro-
mechanical steering only requires energy
when the steering wheel is turned.
With the power steering system, the assisted
steering function automatically adjusts ac-
cording to the vehicle speed, the steering tor-
que and the wheel turning angle. The power
steering only works when the engine is run-
ning. WARNING
If the power steering is not working then the
st eerin

g wheel is much more difficult to turn
and the vehicle more difficult to control.
● The power steering only works when the
engine is
running.
● Never allow the vehicle to move when the
engine is
switched off.
● Never remove the key from the ignition if

le is in motion. The steering may128

Operation
for the vehicle is not too different to the out-
s ide t
emper
ature. It is a good idea to air the
vehicle before starting your journey and to
drive a short distance with the windows
open. Then you can close the windows and
switch on the air conditioning. Keep windows
closed when travelling at high speeds. Driv-
ing with the windows open increases fuel
consumption.
● Switch off the seat heating when the seats
have w
armed up.
● Switch off the heated rear window when it
is not
moist or covered in ice.
Avoid short journeys
Fuel consumption is much higher when the
engine is cold, immediately after it has been
started. It takes a few kilometres of driving
for the engine to warm up and to normalise
consumption.
The engine and catalytic converter need to
reach their proper working temperature in or-
der to minimise fuel consumption and emis-
sions. The ambient temperature has a deci-
sive influence.
Fig. 147 shows the difference in consump-
tion for the same journey at +20 °C (+68 °F)
and at -10 °C (+14 °F).
Therefore, unnecessary short journeys
should be avoided. Try to combine trips. The vehicle uses more fuel in winter than in
summer, ev

en when other conditions are the
same.
The engine takes a long time to warm up
when it is idling. In addition, mechanical
wear and pollutant emissions are also espe-
cially high during this initial warm-up phase.
It is therefore best to drive off immediately af-
ter starting the engine. Doing this avoids run-
ning the engine at a high speed.
Adjusting type pressures.
Having the correct pressure in your tyres
helps to reduce rolling resistance and, as a
result reduces fuel consumption. Increasing
the tyre pressure slightly (+0.2
bar/+3 psi/+200 kPa) can help to save fuel.
When you buy new tyres, make sure they are
optimised for minimum rolling resistance.
Use low friction engine oil
The use of low viscosity totally synthetic oils,
known as low friction engine oil, helps to re-
duce fuel consumption. These oils reduce the
resistance caused by friction in the engine,
they flow around the engine more quickly
and efficiently, particularly in cold starts. The
effect is particularly noticeable in vehicles
frequently used for short journeys.
Always check the engine oil level and ob-
serve service intervals (engine oil change in-
tervals). When purchasing engine oil, always observe
leg
al requirements and ensure that the oil is
approved by SEAT.
Avoid carrying unnecessary loads
The lighter the vehicle, the more economical
and ecological the driving style. For example,
an additional weight of 100 kg will increase
fuel consumption up to 0.3 l/100 km.
Remove any unnecessary objects or loads
from the vehicle.
Remove optional equipment and unnecessa-
ry accessories
The more aerodynamic the vehicle, the lower
the fuel consumption. Optional equipment
and accessories (such as roof racks or bike
carriers) reduce the aerodynamic benefits of
the vehicle.
Therefore, we recommend you remove all op-
tional and unnecessary equipment and racks,
especially if you intend to drive at high
speeds.
Other factors which increase fuel consump-
tion (examples):
● Fault in engine management.
● Driving on hills.

Advice
Cleaning the engine compartment The engine compartment of any motor vehi-
cl
e i
s a potentially hazardous area
››› page 184.
The engine compartment should only be
cleaned by qualified personnel. If it is not
correctly cleaned, the anti-corrosion coating
and consequently electrical components may
be damaged. Moreover, water may filter di-
rectly into the vehicle interior through the wa-
ter chamber ››› .
If the en gine c

ompartment is very dirty, al-
ways take the vehicle to a specialised work-
shop for professional cleaning. SEAT recom-
mends taking your car in for technical serv-
ice.
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

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
banned. Caring for and cleaning the ve-

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.
● 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. 172

Wheels and tyres

lar.
Under-inflation or over-inflation will reduce
the life of the tyres considerably and also im-
pair the car's handling ››› . It is essential to
m aint
ain the c

orrect tyre pressures, especial-
ly if driving at high speeds. Incorrect tyre
pressure causes premature wear and could
cause tyre blow-out.
The pressure should therefore be checked at
least once a month and before starting a
journey.
As a general rule, the pressures given are for
cold tyres. When the tyres are hot, the pres-
sures are greater.
Never deflate a hot tyre in order to obtain the
required pressure. This could result in very
low tyre pressures which may lead to sudden
blow-outs.
Tyre pressure monitoring system
Check tyre pressures only when the vehicle
has not been driven for more than a few kilo-
metres at low speeds in the past three hours.
● The tyre pressures should be checked regu-
larly, and on
ly when the tyres are cold. Al-
ways check all tyres, including the spare
wheel. Tyre pressures should be checked
more often in colder regions, and only when
the vehicle has not been driven recently. Al-
ways use a correctly-operating tyre gauge. ●
Adjust
tyre pressures to the loads carried in
the vehicle.
● After adjusting the tyre pressure, check that
the caps
are properly screwed on.
The spare wheel or temporary spare wheel
must always be kept at the maximum pres-
sure stipulated. WARNING
If tyre pressures are too high or too low, the
tyr e m

ay deflate or burst suddenly while driv-
ing. This could result in a serious accident.
● If the tyre pressure is too low, they could
overhe
at, resulting in tread detachment or
even burst tyres.
● When driving at high speeds and/or fully
loaded, the ty
re could suddenly overheat,
burst or be subject to tread detachment, with
the resultant loss of control of the vehicle.
● Tyre pressures which are too high or too
low reduc
e the service life of the tyre, affect-
ing the vehicle's performance.
● Tyre pressures should be checked regularly,
at le
ast once a month and before long jour-
neys.
● Adjust the pressures of all the tyres to the
vehicl
e load.
● Never deflate excess pressure from hot
tyre
s. CAUTION
● Tak e c

are not to tilt the manometer when
placing it on the valve. Otherwise, the valve
may be damaged.
● If tyre valves are not protected by caps, or if
the caps
are not screwed on correctly, they
may become damaged. Check that the caps
are identical to the standard caps and have
been correctly tightened. For the sake of the environment
Under-inflated tyres will increase fuel con-
sumption. Wear indicator depth profile

le driving, this may indicate
that one of the tyres is damaged.
● Reduce speed immediately and stop, while
obser
ving the highway code.
● Check the wheels and tyres for damage.
● Never carry on driving on worn tyres or
wheels. Reque
st qualified assistance immedi-
ately.
● If there is no visible exterior damage, drive
slowly
and carefully to the nearest special-
ised workshop and have the vehicle checked. Tyre monitor system* 

ith it, the wheel diameter of each
wheel using the ESC. If the diameter of a
wheel changes, the tyre control lamp 
lights up. The wheel diameter changes when:
● Tyre pressure is insufficient.
● The tyre structure is damaged.
● The vehicle is unbalanced because of a
load.
● The wheel

s of one axle are under more
pres
sure (for example, driving with a trailer or
on steep slopes).
● The vehicle is fitted with snow chains.
● The temporary spare wheel is fitted.
● The wheel on one axle is changed.
Tyr
e pressure adjustment
On adjusting tyre pressure or changing one
or more wheels, the ››› Fig. 175 button must
be kept pressed down, with the ignition on,
until an acoustic signal is heard.
If the wheels are under excessive load (for ex-
ample, driving with a trailer or heavy load),
the tyre pressure must be increased to the
recommended value for a full load (see the
sticker on the inside of the fuel flap). If the
tyre monitor system button is pressed down,
the new tyre pressures are confirmed. The tyre pressure control lamp
 lights up
If
the tyre pressure of a wheel is much lower
than the value set by the driver, then the tyre
pressure control lamp ››› will light up.
WARNING
● When the tyr e pr

essure control lamp lights
up, reduce speed immediately and avoid any
sudden turning or braking manoeuvre. Stop
when possible, and check the tyre pressure
and status.
● The driver is responsible for maintaining
correct
tyre pressures. For this reason, tyre
pressure must be regularly checked.
● Under certain circumstances (e.g. when
driving in a s
porty manner, in winter condi-
tions or on a dirt track) the tyre control lamp
may light up belatedly or may function incor-
rectly. Note
If the battery is disconnected, the yellow
warnin g l

amp  lights up after turning the
ignition on. This should turn off after a brief
journey. 203

Technical featuresUrban cycle
Measurement of the urban cycle starts
with an engine cold start. City driving is
then simulated at between 0 and
50 km/h (0 and 31 mph).
Road cycle
In the road cycle simulation, the car un-
dergoes frequent acceleration and
braking in all gears, as in normal every-
day driving. The road speed ranges
from 0 to 120 km/h (0 and 75 mph).
Combined
The average combined consumption is
calculated with a weighting of around
37 % for the urban cycle and 63 % for
the road cycle.
CO
2 emis-
sions of the
combination
The exhaust gases are collected during
both driving cycles to calculate carbon
dioxide emissions (urban and road).
The gas composition is analysed below
to evaluate the CO 2 content and other
emissions. Note
● The kerb w eight

may vary according to the
vehicle equipment. This could raise consump-
tion and the CO 2 emissions slightly.
● In practice, consumption values could be
different
to the values calculated based on
the 715/2007/EC or 80/1268/EEC regula-
tions. Wheels

wheels is 140 Nm. WARNING
● Check the ty

re pressure at least once per
month. Checking the tyre pressure is very im-
portant. If the tyre pressure is too high or too
low, there is an increased danger of accidents
- particularly at high speeds. ●
If the tight enin

g torque of the wheel bolts
is too low, they could loosen while the vehi-
cle is in motion. Risk of accident! If the tight-
ening torque is too high, the wheel bolts and
threads can be damaged. Note
We recommend that you ask your Technical
Ser vic

e for information about appropriate
wheel, tyre and snow chain size. 211
