2015 Seat Leon SC oil additives

The essentials
The level is measured using the dipstick loca-
t ed in the en
gine c
ompartment
›››  page 246.
The oil should leave a mark between zones A and
C . It should never exceed zone
A .
● Zone A : Do not add oil.
● Zone B : You can add oil but keep the level
in th at


zone.
● Zone C : Add oil up to zone
B .

● Unscrew cap from oil filler opening.
● Add oil slowly.
● At the same time, check the level to ensure
you do not a
dd too much.
● When the oil level reaches at least zone B ,
u n
s

crew the engine oil filler cap carefully.

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

Advice
CAUTION
If the oil level is above the area A do not
st ar
t the engine. This could result in damage
to the engine and catalytic converter. Contact
a specialised workshop. For the sake of the environment
The oil level must never be above area A .
Otherw i

se oil can be drawn in through the
crankcase breather and escape into the at-
mosphere via the exhaust system. Note
Before a long trip, we recommend finding an
engine oi l

that conforms to the correspond-
ing VW specifications and recommend keep-
ing it in the vehicle. This way, the correct en-
gine oil will always be available for a top-up if
needed. Changing engine oil
Read the additional information carefully

 page 51.
The engine oil must be changed at the inter-
vals given in the service schedule.
We recommend that you have the engine oil
changed by a Technical Service.
The oil change intervals are shown in the
Maintenance Programme. WARNING
Only change the engine oil yourself if you
hav e the s

pecialist knowledge required!
● Before opening the bonnet, read and ob-
serve the w
arnings ››› page 246.
● Wait for the engine to cool down. Hot oil
may
cause burn injuries.
● Wear eye protection to avoid injuries, such
as ac
id burns, caused by splashes of oil.
● When removing the oil drain plug with your
finger
s, keep your arm horizontal to help pre-
vent oil from running down your arm.
● Wash your skin thoroughly if it comes into
contact
with engine oil.
● Engine oil is poisonous! Used oil must be
stor
ed in a safe place out of the reach of chil-
dren. CAUTION
No additives should be used with engine oil.
This c

ould result in engine damage. Any dam-
age caused by the use of such additives
would not be covered by the factory warranty. For the sake of the environment
● Bec au

se of disposal problems and the spe-
cial tools and specialist knowledge required,
we recommend that you have the engine oil
and filter changed by a Technical Service.
● Never pour oil down drains or into the
ground. ●
Use a s uit

able container when draining the
used oil. It must be large enough to hold all
the engine oil. Cooling system

Top up coolant when the level is below the
MIN (minimum) mark.
Checking coolant level
– Park the vehicle in a horizontal position.
– Switch the ignition off.
– Read off the coolant level on coolant ex-
pan s

ion tank. When the engine is cold, the
coolant level should be between the marks.
When the engine is hot, it may be slightly
above the upper mark.
Topping up coolant
– Wait for the engine to cool down.
– Cover the coolant expansion tank cap with
a cloth and car

efully unscrew it to the left
››› .
– Top up the coolant only if there is still cool-
ant in the e xp

ansion tank, otherwise you
250

Checking and refilling levels
could d amage the engine. If there is no
c oo
lant in the expansion tank, do not con-
tinue driving. You should obtain professio-
nal assistance ››› .
– If there is still some coolant in the expan-
sion t
ank, t

op up to the upper mark.
– Top up with coolant until the level becomes
stab

le.
– Screw the cap back on correctly.
Any lo
ss of coolant fluid normally indicates a
leak in the cooling system. Take the vehicle
straight to a specialised workshop to have
the cooling system examined. If there are no
leaks in the engine cooling system, a loss of
coolant can only occur if the coolant boils
and is forced out of the system as a result of
overheating. WARNING
● The coo lin

g system is under pressure. Do
not unscrew the cap on the coolant expan-
sion tank when the engine is hot: risk of
burns!
● The antifreeze and coolant fluid can be a
health h
azard. Therefore, the antifreeze
should be stored in the original container in a
safe place out of reach of children. Failure to
comply could result in poisoning.
● If working inside the engine compartment,
remember that, ev
en when the ignition is
switched off, the radiator fan may start up au- tomatically, and therefore there is a risk of in-
jury
. WARNING
If there is not enough anti-freeze in the cool-
ant sys

tem, the engine may fail leading to se-
rious damage.
● Please make sure that the percentage of
additiv
e is correct with respect to the lowest
expected ambient temperature in the zone in
which the vehicle is to be used.
● When the outside temperature is very low,
the cool
ant could freeze and the vehicle
would be immobilised. In this case, the heat-
ing would not work either and inadequately
dressed passengers could die of cold. CAUTION
Do not top up the expansion tank with cool-
ant fluid if it

is empty! Air could enter the
cooling system. In this case, stop driving.
Seek specialist assistance. Otherwise, there
is a risk of engine damage. CAUTION
The original additives should never be mixed
with c oo

lants which are not approved by
SEAT. Otherwise, you run the risk of causing
severe damage to the engine and the engine
cooling system.
● If the fluid in the expansion tank is not pur-
ple b
ut is, for example, brown, this indicates that the G13 additive has been mixed with an
ina
dequat

e coolant. The coolant must be
changed as soon as possible if this is the
case! This could result in serious faults and
engine damage. For the sake of the environment
Coolants and additives can contaminate the
en vir

onment. If any fluids are spilled, they
should be collected and correctly disposed
of, with respect to the environment. Brake fluid

Checking the brake fluid level
The brake fluid level must be between the
MIN and MAX markings.
However, if the brake fluid level goes down
noticeably in a short time, or drops below the
MIN mark, there may be a leak in the brake
system. Seek specialist assistance. A warn-
ing light on the instrument panel display
monitors the brake fluid level ››› page 108. »
