2016 Seat Leon 5D check oil

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

 page 50.
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 262.
● 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
266

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 109. »

Wheels
CAUTION
● Some v ehic
les, for example those with the
Start-Stop system* are fitted with a special
battery (AGM-type or EFB-type battery). If any
other type of battery is fitted, the Start-Stop
function may be considerably reduced and
the vehicle may not stop on repeated occa-
sions.
● Make sure that the vent hose is always at-
tached t
o the original opening on the side of
the battery. Gases or battery acid can other-
wise escape and possibly cause damage.
● The battery holder and clamps must always
be correctly
secured.
● Before starting any work on the battery, al-
way
s observe the warnings listed under
››› page 269, Important safety warnings for
handling a vehicle battery .
● Do not forget to replace the battery cover-
ings, wher
e applicable. It is a protection for
high temperatures. This in turn extends the
vehicle service life. For the sake of the environment
 Batteries contain toxic substances includ-
in g s

ulphuric acid and lead. They must be
disposed of appropriately and must not be
disposed of with ordinary household waste.
Make sure disconnected batteries cannot tip
over. Sulphuric acid could be spilt! Wheels
Wheel s
and ty

res
General notes –
When driving with new tyr e
s, be especially
careful during the first 500 km (300 miles).
– If you have to drive over a kerb or similar
obs

tacle, drive very slowly and as near as
possible at a right angle to the obstacle.
– Check from time to time if the tyres are
dam ag

ed (punctures, cuts, cracks or
dents). Remove any foreign objects embed-
ded in the treads.
– Damaged wheels and tyres must be re-
plac

ed immediately.
– Keep grease, oil and fuel off the tyres.
– Replace any missing valve caps as soon as
poss

ible.
– Mark the wheels before taking them off so
that they

rotate in the same direction when
put back.
– When removed, the wheels or tyres should
be stor

ed in a cool, dry and preferably dark
place.
New tyres
New tyres do not give maximum grip straight
away and should therefore be “run in” by driving carefully and at moderate speeds for
about the firs

t 500 km (300 miles). This will
also increase the useful life of the tyres.
The tread depth of new tyres may vary, ac-
cording to the type and make of tyre and the
tread pattern.
Concealed damage
Damage to tyres and rims is often not readily
visible. If you notice unusual vibration or the
car pulling to one side, this may indicate that
one of the tyres is damaged. Reduce speed
immediately if there is any reason to suspect
that damage may have occurred. Inspect the
tyres for damage. If no external damage is
visible, drive slowly and carefully to the near-
est specialised workshop and have the car
inspected.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the di-
rection of rotation on single drive tyres. Al-
ways note the direction of rotation indicated
when mounting the wheel. This guarantees
optimum grip and helps to avoid aquaplan-
ing, excessive noise and wear.
Retrofitting accessories
If you wish to change or fit wheels, rims or
wheel trims, we recommend that you consult
with a SEAT Official Service centre for advice
regarding current techniques.
