2016 Seat Leon 5D engine oil

Operation
Normal temperature
If in norm
al
operations, the diodes light up
until the central zone, it means that the en-
gine has reached operating temperature. At
high outside temperatures and when making
the engine work hard, the diodes may contin-
ue lighting up and reach the upper zone. This
is no cause for concern, provided the control
lamp  does not light up on the instrument
panel digital display.
Heat range
When the diodes light up in the upper area of
the display and the control lamp appears 
on the instrument panel display, the coolant
temperature is excessive ››› page 266. CAUTION
● To en s

ure a long useful life for the engine,
avoid high revs, driving at high speed and
making the engine work hard for approxi-
mately the first 15 minutes when the engine
is cold. The phase until the engine is warm al-
so depends on the outside temperature. If
necessary, use the engine oil temperature*
›››  page 35 as a guide.
● Additional 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 c
oo

ling effect, which could cause
the engine to overheat. Seek specialist assis-
tance. Fuel - Gas level

very low, the lower diode flashes in red.
The yellow control lamp  lights up when the
reserve level has been reached.
The green warning lamp  lights up when the
vehicle is running in natural gas operating
mode. The green warning lamp  switc

hes 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.

Driver messages on the instrument panel
display
Press the clutch
This message appears on vehicles with a
manual gearbox if the driver tries to start the
engine without having the clutch pedal
pressed. The engine will only start if you
press the clutch pedal.
Press the brake This message appears on vehicles with an
automatic gearbox if the driver tries to start
the engine without having the brake pedal
pressed. Select N or P
This me

ssage appears if you try to start or
stop the engine when the selector lever of
the automatic gearbox is not in position P or
N. The engine can only start or stop in certain
positions.
Engage position P; the vehicle
can move; doors can only close in
position P.For safety reasons, this driver message ap-
pears and an audible warning sounds if the
selector lever of the automatic gearbox is not
in position P after you switch off the ignition.
Put the selector lever in position P, otherwise
the vehicle could roll away.
Gear change: selector lever in
the drive position! This driver message is displayed when the
selector lever is not in the position P when
the driver door is opened. Additionally, a
buzzer will sound. Put the selector lever in
position P, otherwise the vehicle could roll
away.
Ignition is switched on
This driver message is displayed and a buz-
zer is sounded when the driver door is
opened with the ignition switched on. WARNING
● Never ru n the en

gine in confined spaces, as
the exhaust gases are poisonous. CAUTION
Avoid high engine speeds, full throttle and
extr eme lo

ad conditions until the engine has
reached its normal operating temperature,
otherwise this can damage the engine. For the sake of the environment
Do not warm up the engine by idling it. You
shoul d driv

e off as soon as you start the en-
gine. This will help avoid unnecessary ex-
haust emissions. Note
● If it i

s difficult to turn the ignition key to
the position 1 , turn the steering wheel to
both side s
to release the steering lock.
● When starting from cold, the engine may be
a little noisy
for the first few seconds until oil
pressure has built up in the hydraulic valve
lifters. This is quite normal, and no cause for
concern.
● If the vehicle battery is disconnected and
reconnect
ed, the key must remain in the posi-
tion 1 for around 5 seconds before starting
up. 168

Operation
Brake servo
The br ak
e ser
vo increases the pressure you
apply to the brake pedal. It works only when
the engine is running. WARNING
● App ly

the brakes heavily to clean the brake
system only in a suitable traffic situation. Do
not put other road users in danger: there is
risk of causing an accident.
● Ensure the vehicle does not move while in
neutral, when the en
gine is stopped. Failure
to follow this instruction could result in an
accident.
● If the brake fluid loses its viscosity and is
subj
ected to heavy use, vapour bubbles can
form in the brake system. This reduces the ef-
ficiency of the brakes. CAUTION
● Never l et

the brakes “drag” by leaving your
foot on the pedal when it is not necessary to
brake. This overheats the brakes, resulting in
longer stopping distances and greater wear.
● Before driving down a long, steep gradient,
it is
advisable to reduce speed and select a
lower gear. This makes use of engine braking
and relieves the brakes. If you still have to
use the brakes, it is better to brake firmly at
intervals than to apply the brakes continu-
ously. Note
● If the br ak

e servo is out of action, for exam-
ple when the car is being towed, you will
have to press the brake pedal considerably
harder than normal to make up for the lack of
servo assistance.
● If you wish to equip the vehicle with acces-
sories s
uch as a front spoiler or wheel covers,
it is important that the flow of air to the front
wheels is not obstructed, otherwise the
brakes can overheat. Braking and stability systems
El ectr
onic

Stability Control (ESC) The ESC helps to improve safety. It reduces
the t
endency
t

o skid and improves the stabil-
ity and roadholding of the vehicle. The ESC
detects critical handling situations, such as
vehicle understeer or oversteer, or wheelspin
on the driving wheels. It stabilises the vehi-
cle by braking individual wheels or by reduc-
ing the engine torque. The warning lamp will
flash on the instrument panel when the ESC
is intervening .
ESC includes the Anti-lock brake system
(ABS), the brake assist system, the traction
control system (ASR), electronic differential
lock (EDL), electronic self-locking*, selective
torque control* and tractor-trailer sway miti- gation*. ESC also helps stabilise the vehicle
by c

hanging the torque.
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up un-
der braking until the vehicle has reached a
virtual standstill. You can continue to steer
the vehicle even when the brakes are on full.
Keep your foot on the brake pedal and do not
pump the brakes. You will feel the brake ped-
al pulsate while the ABS is working.
Brake assist system
The brake assist system can reduce the re-
quired braking distance. The braking force is
automatically boosted if you press the brake
pedal quickly in an emergency. You must
keep pressing the brake pedal until the dan-
ger has passed.
Traction control system (ASR)
In the event of wheelspin, the traction control
system reduces the engine torque to match
the amount of grip available. This helps the
car to start moving, accelerate or climb a gra-
dient.
Electronic differential lock (EDL)
When the EDL detects wheelspin, it brakes
the spinning wheel and directs the power to
the other driven wheel. This function is active
up to approximately 100 km/h (62 mph).

 page 12
Always be aware of the danger of injury and
scalding as well as the risk of accident or fire
when working in the engine compartment
(e.g. when checking and refilling fluids). Al-
ways observe the warnings listed below and
follow all general safety precautions. The en- gine compartment of the vehicle is a poten-
tia
l

ly hazardous area ››› .
WARNING
● Swit c

h the engine off, remove the key from
the ignition and apply the hand brake. If the
vehicle has a manual gearbox, place the lever
in neutral; if it has an automatic gearbox,
place the selector lever in position P. Wait for
the engine to cool down.
● Keep children away from the engine com-
partment
.
● Never spill liquids used for vehicle opera-
tion on the engine comp
artment, as these
may catch fire (e.g. the antifreeze in coolant). 262

Checking and refilling levels
●
Tak e c
are not to cause short circuits in the
electrical system, especially when working
on the battery.
● 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.
● Never cover the engine with additional in-
sul
ating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pans
ion tank when the engine is hot. The
cooling system is under pressure.
● Protect face, hands and arms by covering
the cap with a l
arge, thick rag to protect
against escaping coolant and steam.
● If it is necessary to work in the engine com-
partment
while the engine is running, the ro-
tating components (for example, poly-V belt,
alternator, radiator fan) and the high voltage
ignition system are an additional hazard.
● Observe the following additional warnings
if work
on the fuel system or the electrical
system is necessary:
– Always disconnect the battery from the
on-board network.
– Do not smoke.
– Never work near naked flames.
– Always keep an approved fire extinguish-
er immediately available. CAUTION
When topping up fluids make sure the correct
fluid is p

ut into the correct filler opening, oth-
erwise this can cause serious malfunctions or
engine damage. For the sake of the environment
Inspect the ground underneath your vehicle
re gu

larly so that any leaks are detected at an
early stage. If you find spots of oil or other
fluids in the area where it was parked, have
your vehicle inspected at the workshop. Note
In right-hand drive vehicles* some brake flu-
id re ser

voirs are on the other side of the en-
gine compartment ››› Fig. 240. Opening the bonnet

 page 12
The bonnet is released from inside the vehi-
cle.
Check that the windscreen wiper arms are
not unfolded. Otherwise the paint may be
damaged.
The bonnet can only be unlocked when the
driver door is open. WARNING
Never open the bonnet if you see steam or
drips of

coolant being released from the en-
gine compartment. Failure to comply could
result in burns. Wait until no steam or coolant
can be seen before opening the bonnet. Closing the bonnet
–
Slightly lift the bonnet.
– Release the bonnet stay before pressing it
bac k

into its support.
– Carefully close the bonnet.
– Press the bonnet down until it locks into
plac

e.
– Make sure that the bonnet catches onto its
cla

sp. Do not press down too hard ››› .
WARNING
● For s af

ety reasons the bonnet must always
be completely closed when the vehicle is
moving. Therefore, after closing the bonnet,
always check that the locking element is
properly engaged. This is the case if the bon-
net is flush with the adjacent body panels.
● Should you notice that the bonnet is not
safely
secured when the vehicle is moving,
stop the vehicle immediately and close the
bonnet. Failure to follow this instruction
could result in an accident. 263

Advice
Engine oil Gener a
l
notesThe engine comes with a special, multi-grade
oil
th

at can be used all year round.
Because the use of high-quality oil is essen-
tial for the correct operation of the engine
and its long useful life, when topping up or
changing oil, use only those oils that comply
with VW standards.
The specifications (VW standards) set out in
the following page should appear on the con-
tainer of the service oil; when the container
displays the specific standards for petrol and
diesel engines together, it means that the oil
can be used for both types of engines.
We recommend that the oil change indicated
in the Maintenance Programme, be per-
formed by a technical service or specialised
workshop.
The correct oil specifications for your engine
are listed in the ›››
 page 51, Oil proper-
ties.
Service intervals
Service intervals can be flexible (LongLife
service) or fixed (dependent on time/dis-
tance travelled).
If the PR code that appears on the back of the
Maintenance Programme booklet is PR QI6, this means that your vehicle has the LongLife
serv
ic

e programmed. If it lists the codes QI1,
QI2, QI3, QI4 or QI7, the interval service is
dependent on time/distance travelled.
Flexible service intervals (LongLife service
intervals*)
Special oils and processes have been devel-
oped which, depending on the characteris-
tics and individual driving profiles, enable
the extension of the oil change service (Long-
Life service intervals).
Because this oil is essential for extending the
service intervals, it must only be used ob-
serving the following indications:
● Avoid mixing it with oil for fixed service in-
terv
als.
● Only in exceptional circumstances, if the
engine oil
level is too low ››› page 265 and
LongLife oil is not available, it is permitted to
top up (once) with oil for fixed service inter-
vals ›››
 page 51 (up to a maximum of 0.5
litres).
Fixed service intervals*
If your vehicle does not have the “LongLife
service interval” or it has been disabled (by
request), you may use oils for fixed service
intervals, which also appear in
›››  page 51, Oil properties
. In this case,
your vehicle must be serviced after a fixed in-
terval of 1 year/15,000 km (10,000 miles) (whatever comes first)
›››
Booklet Mainte-
nance Programme.
● In exceptional circumstances, if the engine
oil l
evel is too low ››› page 265 and you can-
not obtain the oil specified for your vehicle,
you can add a small quantity of oil conform-
ing to the specification ACEA A2 or ACEA A3
(petrol engines) or ACEA B3 or ACEA B4 (die-
sel engines) (up to 0.5 l).
Vehicles with diesel particulate filter*
The Maintenance Programme states whether
your vehicle is fitted with a diesel particulate
filter.
Only VW 507 00 engine oil, with reduced ash
formation, may be used in diesel engines
equipped with particulate filter. Using other
types of oil will cause a higher soot concen-
tration and reduce the life of the DPF. There-
fore:
● Avoid mixing this oil with other engine oils.
● Only in exceptional circumstances, if the
engine oil
level is too low ››› page 265 and
you cannot obtain the oil specified for your
vehicle, you can use a small quantity of oil
(once) conforming to the VW 506 00,
VW 506 01, VW 505 00, VW 505 01 or
ACEA B3/ACEA B4 specification. (up to 0.5 l).

level

››› Fig. 241. Top up with engine oil if
necessary. Depending on how you drive and the condi-
tions in whic

h the vehicle is used, oil con-
sumption can be up to 0.5 l/1000 km. Oil
consumption is likely to be higher for the first
5,000 km. For this reason the engine oil level
must be checked at regular intervals, prefera-
bly when filling the tank and before a jour-
ney. WARNING
Any work carried out in the engine compart-
ment or on the en gine mu

st be carried out
cautiously.
