Engine oil additives make new oil darker after the engine has been running
for a shor t
period. This is normal and does not mean more frequent oil
changes are required. WARNING
If, in exceptional circumstances, you must change the engine oil yourself,
pl e
ase note the following:
● Wear eye protection.
● Always wait until the engine has completely cooled to avoid being
burned.
● Alw
ays keep your arms horizontal when unscrewing the oil drainage
bolt so th
at the oil does not run down your arms when it begins to drain.
● Use a suitable and large enough container to collect all of the used oil
in the engine.
● Never c
ollect engine oil in empty food containers, cans, bottles and
other container
s as not all people are able to identify engine oil.
● Oil is toxic and must be kept out of the reach of children. For the sake of the environment
Before changing the engine oil, find a suitable location or service for proper
dis po
sal. For the sake of the environment
Always dispose of engine oil with the utmost respect for the environment.
Never di s
pose of used engine oil in places such as a garden, woods, drains,
roads, paths, rivers and drainage systems. Engine coolant

Checking and refilling levels WARNING
If the warning lamps and messages are ignored, the vehicle may stall in
traffic, or m a
y cause accidents and severe injuries.
● Always observe any lit warning lamps and text messages.
● Never ignore the warning lamps or text messages.
● Stop the vehicle safely as soon as possible. CAUTION
Failure to heed the warning lamps and text messages when they appear
ma y
result in faults in the vehicle.
Engine coolant specifications The engine cooling system comes with a special mixture of water and at
le
a
st 40% G 12 plus-plus (TL-VW 774 G) or G 12 plus (TL-VW 774 F) engine
coolant additive. Both are easily recognisable because they are purple in
colour.
This mixture gives the necessary frost protection down to -25°C (-13°F) and
protects the alloy parts of the cooling system against corrosion. It also pre-
vents scaling and raises the boiling point of the coolant.
To protect the engine cooling system, the proportion of additive must al-
ways be at least 40%, even if frost protection is not required in countries
with a warm climate.
If greater frost protection is required in very cold climates, the proportion of
additive can be increased. However, the percentage of additive should not
exceed 60 %, as this would reduce the frost protection and, in turn, de-
crease the cooling capacity. When adding coolant, a mixture of
disti
lled water and at least 40 % of the
additive G 12 plus-plus must be use to ensure optimum rust protection
⇒ .
WARNING
In the event of insufficient antifreeze protection in the engine cooling
sys t
em, the engine could be damaged and severe injuries caused.
● Ensure that the proportion of engine coolant additive corresponds to
the lowe
st outside temperature to which the vehicle will be exposed.
● If the outside temperature is extremely low, the engine coolant could
freeze c
ausing the vehicle to stop. As this would also cause the heating
to stop working, passengers without sufficient clothing could freeze. CAUTION
Never mix genuine additives with other additives that are not approved by
SEA T
. Otherwise, you run the risk of causing severe damage to the engine
and the engine cooling system.
● The engine coolant G 12 plus-plus can be mixed with G 12 plus and
G 11.
● If the fluid in the expansion reservoir is not purple but, for example,
brown, thi
s means that you have mixed G 12 plus-plus or G 12 plus with an-
other coolant. The coolant must be changed as soon as possible if this is
the case! Failure to observe this point will result in serious malfunctions and
engine damage! For the sake of the environment

If the coolant level is low, the coolant warning indicator will light. Preparations
●
Park the vehicle on even, flat and firm ground.
● Allow the engine to cool ⇒ .
● Open the bonnet ⇒ p
age 275.
● The coolant expansion reservoir is easily recognisable because of the
symbol
on the cap ⇒ fig. 172.
Checking the engine coolant level
● When the engine is cold, check the coolant level using the side marking
on the expan
sion reservoir ⇒ fig. 171.
● If the level is below the “MIN” mark, top up with coolant. When the en-
gine is hot
it may be slightly above the marked area.
Topping up the engine coolant level
● Always protect your face, hands and arms from hot coolant and steam
usin
g a large, thick cloth over the coolant expansion tank cap.
● Remove the cap very carefully ⇒ .
● Only refill using new engine coo
lant according to SEAT specifications
(⇒ page 285) ⇒ .
● The engine coolant level should be between the marks on the coolant
exp an
sion tank ⇒ fig. 171. Do not exceed the top level of the marked area
⇒ .
● Screw on the cap tightly.
● If, the event of an emergency, you have no coolant that is compliant to
the requir ed s
pecifications ( ⇒ page 285), never use another type of addi-
tive. Instead, first top up with distilled water ⇒ only. Then re-establish
the corr ect
proportion of the mixture with the correct additive as soon as
possible ⇒ page 285.
287
Checking and refilling levels WARNING
Hot vapours and coolant can cause serious burns.
● Never open the coolant expansion tank if steam or coolant is coming
from the en gine c
ompartment. Wait until you cannot see or hear any
steam or coolant escaping.
● Always wait until the engine has completely cooled before very care-
ful
ly opening the expansion tank cap. Contact with hot elements of the
engine can cause skin burns.
● Once the engine has cooled, follow the instructions below before
opening the bonnet:
–Turn on the el
ectronic parking brake and place the gear selector
lever in P or the g
ear stick in neutral.
– Remove the key from the ignition.
– Keep children away from the engine compartment and never leave
them uns
upervised.
● When the engine is warm or hot, the cooling system is pressurised!
Do not un
screw the cap on the expansion tank when the engine is hot.
Otherwise, coolant may spray out under pressure causing burns and seri-
ous injury.
–Carefully and slowly unscrew the cap anticlockwise, gently press-
ing down on it
.
– Always protect your face, hands and arms from hot coolant and
ste
am using a large, thick cloth.
● When refilling liquids, avoid spilling them on parts of the engine and
the exhau
st system. Spilled liquids could cause a fire. Under specific cir-
cumstances, the ethylene glycol can catch fire. CAUTION
● Top up with distilled water only. Any other type of water may lead to con-
s ider
able rusting in the engine due to its chemical components. This could
consequently damage the engine. If you have not used distilled water but
another type of water to top up the coolant, a specialist workshop must im-
mediately replace all of the fluid in the engine cooling system.
● Only top up coolant to the top level of the marked area ⇒ fig. 171. Other-
wi
se the excess coolant will be forced out of the cooling system when the
engine is hot, causing damage.
● If a lot of liquid coolant has been lost, wait for the engine to cool do
wn
completely before adding coolant. Extensive coolant loss is an indication of
leaks in the engine cooling system. Have the engine cooling system inspec-
ted immediately by a Technical Service. Otherwise you may damage the en-
gine.
● When refilling or changing service liquids, ensure that you put the liq-
uids int
o the right tank. Making a mistake when refilling could cause seri-
ous malfunctions and damage the engine! Safety First Operating instructions Practical tips Technical Data
