Coolant specifications
The engine cooling system is supplied from
the factory with a specially treated mixture of
water and at least 40 % of the additive G13
(TL-VW 774 J), purple. This mixture gives the
necessary frost protection down to -25 °C
(-13 °F) and protects the light alloy parts of
the engine cooling system against corrosion.
It also prevents scaling and considerably rai-
ses the boiling point of the coolant.
To protect the cooling system, the percentage
of additive must always be at least 40 %, even in warm climates where anti-freeze pro-
tection is

not required.
If for weather reasons further protection is
necessary, the proportion of additive may be
increased, but only up to 60 %; otherwise an-
tifreeze protection will diminish and this will
worsen cooling.
When the coolant is topped up, use a mixture
of distilled water and at least 40 % of the
G13 or G12 plus-plus (TL-VW 774 G) additive
(both are purple) to obtain an optimum anti-
corrosion protection ››› in Checking the
c oo
l

ant level and topping up on page 191.
The mixture of G13 with G12 plus (TL-VW 774
F), G12 (red) or G11 (green-blue) engine cool-
ants will significantly reduce anti-corrosion
protection and should therefore be avoided

The essentials
WARNING
If the vehicle is not correctly raised, it could
fa l
l off the jack causing serious injury. Please
observe the following rules to minimise the
risk of injury:
● You should only use a jack approved by
SEAT f
or your vehicle. Other jacks, even those
approved for other SEAT models, might slip
out of place.
● The ground should be firm and flat. If the
ground i
s sloped or soft then the vehicle
could slip and fall off the jack. If necessary,
support the jack on a wide solid base.
● If the ground is slippery, such as tiles,
plac
e a non-slip surface (a floor mat, for in-
stance) beneath the jack to avoid slipping.
● Only fit the jack at the prescribed jacking
points. The c
law of the jack should grip the
reinforcement nerve on the underbody
››› Fig. 56.
● You should never place a body limb such as
an arm or leg u
nder a raised vehicle that is
solely supported by the jack.
● If you have to work underneath the vehicle,
you mus
t use suitable stands additionally to
support the vehicle, there is a risk of acci-
dent!.
● Never raise the vehicle if it is tilting to one
side or the engine i
s running.
● Never start the engine when the vehicle is
raised.
The vehicle may come loose from the
jack due to the engine vibrations. Removing and fitting a wheel

Place the s
pare wheel or temporary spare
wheel into position.
● Replace the wheel bolts and tighten slight
-
ly using the hexagonal socket on the end of
the wheel brace.
● To tighten the anti-theft locking wheel bolts
use the corr
esponding adaptor.
● Lower the car with the jack.
● Tighten all of the wheel bolts clockwise
›››
. Tighten the bolts in diagonal pairs (not
in a c ir
c
le).
● Put the caps, trim or full hubcap back on
›››
page 36. WARNING
If the wheel bolts are not treated suitably or
not tight ened t

o the correct torque then this
could lead to loss of vehicle control and to a
serious accident.
● All the wheel bolts and hub threads should
be cle
an and free of oil and grease. The wheel
bolts should be easily tightened to the cor-
rect torque.
● The hexagonal socket in the wheel brace
should be u
sed for turning wheel bolts only.
Do not use it to loosen or tighten the wheel
bolts. 39

Operation
Outside temperature indicator!
When the outs ide t
emper
ature is below +4 °C
(+39 °F), the symbol “ice crystal” (warning of
risk of freezing) is also displayed next to the
temperature. At first this symbol flashes and
then it remains lit until the outside tempera-
ture rises above +6 °C (+43 °F) ››› .
When the v
ehic

le is stationary or travelling at
very low speeds, the temperature displayed
may be slightly higher than the actual out-
side temperature as a result of heat coming
from the engine.
The temperatures measured range from
-40 °C to +50 °C (-40 °F to +122 °F).
Selector lever position
The range of engaged gears of the selector
lever is shown on the side of the lever, and
on the instrument panel display. In positions
D and M, and with the Tiptronic, the corre-
sponding gear is also indicated on the dis-
play.
Recommended gear* (manual gearbox)
The recommended gear to save fuel can be
displayed on the instrument panel display
while you are driving ››› page 137.
Seat belt status display for the rear seats*
The seat belt status display on the instru-
ment panel display informs the driver, when
the ignition is switched on, whether any pas- sengers in the rear seats have fastened their
seat belts

››› page 51.
Start-Stop system status display
The instrument panel display shows informa-
tion on the current status ››› page 156. WARNING
If the warning lamps are ignored, the vehicle
ma y

stall in traffic, or may cause accidents
and severe injuries.
● Never ignore the warning lamps.
● Stop the vehicle safely as soon as possible.
● A faulty vehicle represents a risk of acci-
dent for the driv
er and for other road users. If
necessary, switch on the hazard warning
lamps and put out the warning triangle to ad-
vise other drivers.
● Park the vehicle away from traffic and en-
sure th
at no highly flammable materials are
under the vehicle that could come into con-
tact with the exhaust system (e.g. dry grass,
fuel). WARNING
Even though outside temperatures are above
freez in

g, some roads and bridges may be icy.
● At outside temperatures above +4°C
(+39°F), even when the “ice c
rystal symbol”
is not visible, there may still be patches of ice
on the road. ●
Never r ely

ay result in faults in the vehicle. Note
● Differ ent

versions of the instrument panel
are available and therefore the versions and
instructions on the display may vary.
● When several warnings are active at the
same time, the symbol

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
the vehic
le is in motion. The steering may128

ped al, and al
lo
w for longer stopping distan-
ces.
Brake servo
The brake servo only operates when the en-
gine is running and the pressure applied by
the driver on the brake pedal increases.
If the brake servo does not operate or the ve-
hicle must be towed, then the brake pedal
will have to be pressed with more force given
that the braking distance will be increased
when the brake servo does not operate ››› .
WARNING
New brake pads do not brake to full efficien-
cy.
● For the fir

st 320 km, new brake pads have
not y
et reached their maximum braking ca-
pacity, and need to be “run in” first. For this,
to compensate for reduced braking efficiency
the brake pedal will have to be pressed with
more force.
● To avoid losing control of the vehicle and
caus
ing serious accidents, always take great
care when driving with new brake pads.
● When running in new brake pads, always
res
pect the safety distances between you and
other vehicles and do not cause situations re-
quiring extreme braking performance. WARNING
When brakes overheat, braking is less effi-
cient and br

aking distances increase.
● When driving on slopes, brakes can be
overlo
aded and overheat quickly.
● Reduce speed or change down a gear when
faced w
ith steep and long slopes. This allows
you to use the engine braking effect and to
reduce the strain on the brake system.
● Non-standard or damaged front spoilers
coul
d restrict the airflow to the brakes and
cause them to overheat. WARNING
Wet, frozen or salt-covered brakes take lon-
ger t o en

gage and this increases braking dis-
tances.
● Test the brakes carefully.
● Dry the brakes, free them of ice and salt by
brakin
g gently several times, when visibility,
weather, and road and traffic conditions per-
mit. WARNING
Driving without the brake servo may signifi-
cantly inc

rease the braking distance and re-
sult in a severe accident.
● Never allow the vehicle to move forwards
when the engine is
switched off.
● If the brake servo does not operate or the
vehicl
e must be towed, then the brake pedal will have to be pressed with more force given
that
the br

aking distance will be increased
when the brake servo does not operate. CAUTION
● Nev er m ak

e the brakes “slip” by pressing
the pedal gently, if it is not really necessary
to brake. Continuously pressing on the brake
pedal will heat the brakes. This could signifi-
cantly reduce braking power, increase brak-
ing distance or even result in the total failure
of the brake system.
● Reduce speed or change down a gear when
faced w
ith steep and long slopes. This allows
you to use the engine braking effect and to
reduce the strain on the brake system. Other-
wise, the brakes may overheat and fail. Only
use the brakes to reduce speed or to stop. Note
Make use, when having the front brake pads
chec k

ed, and have the rear pads checked al-
so. The thickness of the brake pads should be
checked visually and regularly, by looking
through the openings in the wheel rims or
from underneath the vehicle. If necessary, re-
move the wheels to check them thoroughly.
SEAT recommends taking your car in for tech-
nical service. 136

Operation
running, the internal friction in the engine is
gr e
at
er than later on when all the moving
parts have bedded down.
How the vehicle is driven for the first 1,500
km influences the future engine perform-
ance. Throughout the life of the vehicle, it
should be driven at a moderate speed, espe-
cially when the engine is cold, as this will re-
duce engine wear and increase its useful life.
Never drive at extremely low engine speeds.
Change down to a lower gear when the en-
gine no longer runs “smoothly”. Up to 1,000
kilometres the following instructions apply:
● Do not use full throttle.
● Do not force the engine above two thirds of
its max
imum speed.
Between 1,000 and 1,500 kilometres, gradu-
ally increase power until reaching the maxi-
mum speed and high engine speeds.

page 132 For the sake of the environment
If the engine is run in gently, the life of the
engine w i

ll be increased and the engine oil
consumption reduced. Environmental compatibility
Environmental protection is a top priority in
the des
ign, c

hoice of materials and manufac-
ture of your new SEAT.
Constructive measures to encourage recy-
cling
● Joints and connections designed for easy
dismantlin
g
● Modular construction to facilitate disman-
tling
● Incr

eased use of single-grade materials.
● Plastic parts and elastomers are marked in
acc or

dance with ISO 1043, ISO 11469 and
ISO 1629.
Choice of materials
● Use of recycled materials.
● Use of compatible plastics in the same part
if its c
omponents are not easily separated.
● Use of recycled materials and/or materials
originating fr
om renewable sources.
● Reduction of volatile components, includ-
ing odour, in p
lastic materials.
● Use of CFC-free coolants.
Ban on heavy
metals, with the exceptions
dictated by law (Annex II of ELV Directive
2000/53/EC): cadmium, lead, mercury, hexa-
valent chromium. Manufacturing methods
●
Reduction of the quantity of thinner in the
protectiv
e wax for cavities.
● Use of plastic film as protection during ve-
hicle tr
ansport.
● Use of solvent-free adhesives.
● Use of CFC-free coolants in cooling sys-
tems.
● Recy

cling and energy recovery from resi-
dues (RDF).
● Impr

ovement in the quality of waste water.
● Use of systems for the recovery of residual
heat (therm
al recovery, enthalpy wheels,
etc.).
● The use of water-soluble paints.

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.
