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

Air conditioning
●
The max imum he
at output required to de-
frost windows as quickly as possible is only
available when the engine has reached its
normal running temperature. Only drive when
you have good visibility.
● Always ensure that you use the heating
syst
em, ventilation, air conditioner and the
heated rear window to maintain good visibili-
ty.
● Never leave the air recirculation on for a
long period of time. If
the cooling system is
switched off and air recirculation mode
switched on, the windows can mist over very
quickly, considerably limiting visibility.
● Switch air recirculation mode off when it is
not requir
ed. WARNING
Stuffy or used air will increase fatigue and re-
duce driv er c

oncentration possibly resulting
in a serious accident.
● Never leave the fresh air fan turned off or
use the air rec
irculation for long periods of
time; the air in the vehicle interior will not be
refreshed. CAUTION
● Swit c

h the air conditioner off if you think it
may be broken. This will avoid additional
damage. Have the air conditioner checked by
a specialised workshop.
● Repairs to the air conditioner require spe-
cia
list knowledge and special tools. SEAT rec-
ommends taking your car in for technical
service. Note
● When the coo lin

g system is turned off, air
coming from the outside will not be dried. To
avoid fogging up the windows, SEAT recom-
mends leaving the cooler (compressor) on. To
do this, press the A/C button. The button
lamp shou l

d light up.
● The maximum heat output required to de-
fros
t windows as quickly as possible is only
available when the engine has reached its
normal running temperature.
● Keep the air intake slots in front of the
winds
creen free of snow, ice and leaves to en-
sure heating and cooling are not impaired, and to prevent the windows from misting

Air conditioner user instructions* The interior cooling system only works when
the engine i
s

running and the fan is switched
on.
The air conditioning operates most effective-
ly with the windows closed. However, if the
vehicle has heated up after standing in the
sun for some time, the air inside can be cooled more quickly by opening the windows
briefly.
Settin

or conditions of optimal visibility
When the air conditioning is switched on, the
temperature and the air humidity in the vehi-
cle interior drop. In this way, when the out-
side air humidity is high, the windows do not
mist over and comfort for the vehicle occu-
pants is improved.

utton will light up.
The air conditioning system does not switch
on
If the air conditioning system cannot be
switched on, this may be caused by the fol-
lowing: ●
The engine is
not running.
● The fan is switched off.
● The air conditioner fuse has blown.
● The outside temperature is lower than ap-
prox
imately +2 °C (+36 °F).
● The air conditioner compressor has been
temporari
ly switched off because the engine
coolant temperature is too high.
● Another fault in the vehicle. Have the air
conditioner chec
ked by a specialised work-
shop. Special features
If the humidity and t

emperature outside the
vehicle are high, condensation can drip off
the evaporator in the cooling system and
form a pool underneath the vehicle. This is
normal and does not indicate a leak! Note
After starting it, any residual humidity in the
air conditioner c ou

ld mist over the wind-
screen. Switch on the defrost function as
soon as possible to clear the windscreen of
condensation. Air outlets

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

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.
Running in new tyres and brake pads

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.

Driving
Economical and environmentally
friendly driv
in
gFig. 147
Fuel consumption in litres per
100 km at 2 diff
er

ent outside temperatures Fuel consumption, environmental impact and
en
gine, br
ak

e and tyre wear depend largely
on three factors:
● Personal driving style.
● Conditions of use (weather, road surface).
● Technical requirements.
Saving
s of up to 25% in fuel consumption
are possible with an appropriate driving style
and the adoption of certain simple tips.
Changing gear early
General instructions: The highest gear is al-
ways the most economical. As a guide, for
most vehicles at a speed of 30 km/h
(19 mph), drive in third gear, at 40 km/h (25 mph) in fourth gear and at 50 km/h
(31 mph) in fifth ge

ar.
In addition, “skipping” gears when shifting
up helps to save fuel, weather and traffic
conditions permitting.
Do not wait until the last moment before
changing gear. Only use first gear when you
move off and change to second gear quickly.
Avoid the kick-down function in vehicles with
automatic gearbox.
Vehicles with a gear display help to achieve
an economical driving style as the display in-
dicates the best moment to change gear.
Let the vehicle roll
If you take your foot off the accelerator, the
fuel supply is stopped and consumption is
reduced.
Allow the vehicle to roll without accelerating,
for example when approaching a red traffic
light. However, if the vehicle is rolling too
slowly or the distance is too long, the clutch
pedal should be pressed to declutch. The en-
gine will then operate at idle speed.
If the vehicle is going to be at a standstill for
a period of time, switch off the engine; for ex-
ample, while waiting at a level crossing.
Think ahead and “flow” with the traffic
Frequent acceleration and braking considera-
bly increase fuel consumption. If you think ahead as you drive and keep a safe distance
from the v
ehicle in front, it is possible to slow
down by simply lifting your foot off the accel-
erator. This eliminates the need for constant
braking and acceleration.
Calm and steady driving
Constancy is more important than speed: The
more you drive at a constant speed, the lower
the fuel consumption.
When driving on the motorway, it is more effi-
cient to drive at a constant and more moder-
ate speed than to be continuously accelerat-
ing and braking. As a general rule, you will
reach your destination just as quickly when
you drive at a constant speed.
The cruise control function helps you to ach-
ieve a constant style of driving.
Moderate use of additional devices
It is important to travel in comfort, but con-
venience systems should be used ecological-
ly.
Some equipment, when connected, increase
fuel consumption considerably, for example:
● Air conditioning cooling system: If the air
conditioning sy
stem is required to cool to
significantly lower temperatures than the true
outside temperature, it will require a large
amount of energy from the engine. Therefore,
we recommend that the selected temperature »
