2013 Seat Mii engine

186In the engine compartment
The correct oil must be used to ensure the correct operation and long serv-
ice life of the engine. The engine comes with a high-quality multigrade oil
that can generally be used all year round.
Only use an engine oil that complies to SEAT standards whenever possible
⇒ 
. Only refill engine oil using approved engine oil in accordance with the
corresponding SEAT standard ( ⇒ table on page 186). All oils indicated are
synthetic multigrade oils .
Engine oils are being continuously further developed. Technical Services
are permanently informed of any modifications. SEAT therefore recommends
that you have the engine oil changed by a Technical Service.

In the engine compartment
● Open the bonnet  ⇒  page 180.
● The engine oil filler neck can be recognised by the symbol  on the
cap ⇒ Fig. 115 and the dipstick by its coloured handle.
Check the engine oil level
● Pull out the dipstick and wipe it on a clean cloth.
● Replace the dipstick, pushing it in as far as it will go. If the dipstick to
measure engine oil has a mark, when you reintroduce it this mark should
slot into the corresponding groove located on the upper end of the tube.
● Remove the dipstick again and check the engine oil level ⇒ table on
page 187.
● After reading the oil level, replace the dipstick in the tube completely.
Engine oil topping up ranges
Fig. 114Operations required depending on the engine oil topping
up level:
Area ADo not top up oil
⇒ .Area BYou can add oil, but keep the level in this zone.
Area COil
must be added. After topping up the oil level should be
in area B.
Adding oil after checking the level
Only add engine oil in small quantities and in steps.
●
Unscrew the cap from engine oil filler neck on the cylinder head
⇒ Fig. 115. If you are not sure where the cap is, request help from a special-
ist.
● Only refill using approved SEAT engine oil in small quantities (no more
than 0.5 ltr) ⇒ page 185.
● To avoid adding too much oil, each time you add a quantity, wait until
the oil has flowed into the crankcase so that it can be measured with the
dipstick.
● Check the oil level before adding any more oil. Do not top up with too
much engine oil ⇒ 
. ●
When the oil level is in at least the ⇒ Fig. 114 B
zone, insert the dip-
stick into the tube fully to avoid engine oil escaping when the engine is run-
ning.
● After topping up the oil, ensure that the cap is screwed on to the filler
neck correctly.
WARNING
Oil could catch fire if it comes into contact with hot engine components.
This could lead to a fire, explosion and severe injuries.
● Always ensure that after topping of oil, the engine oil filler cap is cor-
rectly tightened. This will avoid engine oil spilling onto hot engine parts
when the engine is running.
CAUTION
● If the engine oil level is above the area A do not start the engine. Seek
specialist assistance. Otherwise catalytic converter and engine damage may
occur.
● When refilling or changing service liquids, ensure that you put the liq-
uids into the right tank. Making a mistake when refilling could cause seri-
ous malfunctions and damage the engine!
For the sake of the environment
The oil level must never be above area A. Otherwise oil can be drawn in
through the crankcase breather and escape into the atmosphere via the ex-
haust system. 
Engine oil consumption
The consumption of engine oil can be different from one engine to another
and can vary during the useful life of the engine. 
Vehicle diagramPrior to a journey...While drivingCare, cleaning and mainte-
nanceIf and whenTechnical specifications

188In the engine compartment
Depending on how you drive and the conditions in which the vehicle is
used, oil consumption can be up to 1 ltr./2000 km. In the case of new vehi-
cles, the consumption can exceed this figure over 5000 kilometres. For this
reason the engine oil level must be checked at regular intervals, preferably
when filling the tank and before a journey.
When the engine is working hard, for instance during sustained high-speed
motorway cruising in summer, or when climbing mountain passes, the oil
level should preferably be kept within area ⇒ Fig. 114 A
. 
Changing the engine oil
The engine oil must be changed regularly according to the specifications of
the Maintenance Programme.
Due to the problems linked with disposing of used oil and the need for suit-
able tools and special knowledge, always visit a specialised workshop to
have the engine oil and filter changed. SEAT recommends visiting a Techni-
cal Service.
Detailed information on the service intervals are shown in the Maintenance
Programme.
Engine oil additives make new oil darker after the engine has been running
for a short 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,
please note the following:
● Wear eye protection.
WARNING (Continued)
● Always wait until the engine has completely cooled to avoid being
burned.
● Always keep your arms horizontal when unscrewing the oil drainage
bolt so that 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 collect engine oil in empty food containers, cans, bottles and
other containers 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
disposal.
For the sake of the environment
Always dispose of engine oil with the utmost respect for the environment.
Never dispose of used engine oil in places such as a garden, woods, drains,
roads, paths, rivers and drainage systems. 

Engine coolant Introduction
Never work on the engine cooling system or if you are not familiar with the
operations to be carried out, the applicable safety standards and especially
if you do not have the instruments, liquids and tools necessary ⇒ 
! In
such a case, have any work carried out by a Specialised workshop. SEAT rec-
ommends visiting a Technical Service.
Negligent work can cause serious injury.
Additional information and warnings:
● Working in the engine compartment ⇒ page 180
● Accessories, parts replacement, repairs and modifications ⇒ page 222
WARNING
Engine coolant is toxic!
● Only keep engine coolant in its original container, tightly shut and in
a safe place.
● Never store engine coolant in empty food containers or bottles as
other people may accidentally drink it.
● Always keep engine coolant out of reach of children.
● Ensure that the proportion of engine coolant additive corresponds to
the lowest outside temperature to which the vehicle will be exposed.
● If the outside temperature is extremely low, the engine coolant could
freeze causing the vehicle to stop. As this would also cause the heating
to stop working, vehicle occupants without sufficient clothing could
freeze.
For the sake of the environment
Coolants and additives can contaminate the environment. Collect any spilt
fluids in suitable containers and dispose of in accordance with legislation
and with the utmost respect for the environment. 

WARNING
If the warning lamps are ignored, the vehicle may stall in traffic, or may
cause accidents and severe injuries.
● Always observe any lit warning lamps.
● Never ignore the warning lamps.
● Stop the vehicle safely as soon as possible.
CAUTION
Failure to heed the warning lamps when they appear may result in faults in
the vehicle.
Note
On the display of the Portable Navigation System (supplied by SEAT)
⇒ page 222 an engine coolant temperature gauge can be seen. 
Engine coolant specifications
The engine cooling system is supplied from the factory with a specially trea-
ted mixture of water and, at least, 40 % of the additive G 13 (TLVW 774 J).
The engine coolant additive is recognisable by its purple colour. This mix-
ture of water and additive gives the necessary frost protection down to -25
°C (-13 °F) and protects the light alloy parts of the cooling system against
corrosion. It also prevents scaling and considerably raises the boiling point
of the coolant.
To protect the engine cooling system, the percentage of additive must al-
ways be at least 40 %, even in warm climates where anti-freeze protection is
not required.
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 the coolant is topped up, use a mixture of
distilled water and, at
least, 40 % of the G 13 or G 12 plus-plus (TL-VW 774 G) additive (both are
purple) to obtain an optimum anticorrosion protection ⇒ 
. The mixture of
G 13 with G 12 plus (TL-VW 774 F), G 12 (red) or G 11 (green-blue) engine
coolants will significantly reduce the anticorrosion protection and should,
therefore be avoided ⇒ 
.
WARNING
If there is not enough anti-freeze in the coolant system, the engine may
fail leading to serious damage.
● Please make sure that the percentage of additive is correct with re-
spect 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 coolant could freeze
and the vehicle would be immobilised. In this case, the heating would
not work either and inadequately dressed passengers could die of cold.
CAUTION
The original additives should never be mixed with coolants 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 purple but is, for example,
brown, this indicates that the G 13 additive has been mixed with an inade-
quate 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 environment. If any fluids are
spilled, they should be collected and correctly disposed of, with respect to
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  ⇒ page 180.
● The coolant expansion tank is easily recognisable because of the sym-
bol  on the cap ⇒  Fig. 117.
Checking the engine coolant level
● When the engine is cold, check the coolant level using the side marking
on the expansion tank ⇒ Fig. 116.
● 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
using a large, thick cloth over the coolant expansion tank cap.
● Remove the cap very carefully ⇒ 
.
● Only refill using new engine coolant according to SEAT specifications
(⇒ page 190) ⇒ 
.
● The engine coolant level should be between the marks on the coolant
expansion tank ⇒ Fig. 116. 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 required specifications ( ⇒ page 190), never use another type of addi-
tive. Instead, first top up with distilled water ⇒ 
only. Then re-establish
the correct proportion of the mixture with the correct additive as soon as
possible ⇒ page 190. 

WARNING
Hot vapours and coolant can cause serious burns.
● Never open the coolant expansion tank if steam or coolant is coming
from the engine compartment. Wait until you cannot see or hear any
steam or coolant escaping.
● Always wait until the engine has completely cooled before very care-
fully 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:
–Engage the handbrake and place the gear selector lever in P or the
gear stick in neutral.
– Remove the key from the ignition.
– Keep children away from the engine compartment and never leave
them unsupervised.
● When the engine is warm or hot, the cooling system is pressurised.
Do not unscrew 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
steam using a large, thick cloth.
● When refilling liquids, avoid spilling them on parts of the engine and
the exhaust 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-
siderable 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 specialised workshop must
immediately replace all of the fluid in the engine cooling system.
● Only top up coolant to the top level of the marked area ⇒ Fig. 116. Oth-
erwise 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 down
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 specialised workshop. Otherwise engine damage may
occur.
● When refilling or changing service liquids, ensure that you put the liq-
uids into the right tank. Making a mistake when refilling could cause seri-
ous malfunctions and damage the engine! 
