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 %, 52

The essentials
even in warm climates where anti-freeze pro-
t ection i
s
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 Topping up cool-
ant on p ag
e 251

. The mixture of G13 with
G12 plus (TL-VW 774 F), G12 (red) or G11
(green-blue) engine coolants will significant-
ly reduce anti-corrosion protection and
should therefore be avoided ››› in Topping

Operation
●
Addition a
l lights and other accessories in
front of the air inlet reduce the cooling effect
of the coolant. At high outside temperatures
and high engine loads, there is a risk of the
engine overheating.
● The front spoiler also ensures proper distri-
bution of the c
ooling air when the vehicle is
moving. If the spoiler is damaged this can re-
duce the cooling effect, which could cause
the engine to overheat. Seek specialist assis-
tance. Fuel - Gas level

when the ignition is switched on. When the

appears ››› page 104. When the fuel level is
very low, the lower diode flashes in red. The yellow control lamp 
lights up when the

serve level has been reached.
The green warning lamp  lights up when the
vehicle is running in natural gas operating
mode.
The green warning lamp  switches off when
the natural gas is exhausted. The engine
changes to operate with petrol.
Problem: If the vehicle is left parked for a
long time immediately after refuelling, the
natural gas level indicator may not accurately
indicate the same level shown after refuelling
when the vehicle is started up again. This is
not due to a leak in the system, but to a drop
in pressure in the gas tank for technical rea-
sons after a cooling phase just after refuel-
ling.

Never run the fuel tank completely dry. An ir-

Operation
WARNING
Reduced visibility through the windows in-
cr e
ases the risk of serious accidents.
● Always ensure that all windows are free of
ice and sno
w, and that they are not fogged,
so as to maintain good visibility of everything
outside.
● 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. Only drive when
you have good visibility.
● Always ensure that you use the heating
syst
em, fresh air system, air conditioner and
the heated rear window to maintain good visi-
bility to the outside.
● 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 visiting a SEAT Official Service. Note
● When the coo lin

g system is turned off, air
coming from the outside will not be dried. To
prevent fogging of the windows, SEAT recom-
mends leaving the cooling system (compres-
sor) turned on. To do this, press the button  . The button lamp should light up.
● The maximum heat output required to de-
fro s

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
over. Adjust using the Easy Connect sys-
t
em* 3 Applies to vehicles with a Touch/Colour Media
S y

stem.
In the Easy Connect system it is also possible
to perform various adjustments to the Clima-
