Checking and refilling levels
WARNING
Never open the bonnet if you see steam or drips of coolant being re-
leased from the engine 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 raise the bonnet.
– Release the bonnet stay before pressing it back into its support.
– Carefully close the bonnet.
– Press the bonnet down until it locks into place.
– Make sure that the bonnet catches onto its clasp. Do not press
down too hard ⇒ 
.
WARNING
● For safety 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 bonnet is flush with the adjacent body panels.
● Should you notice that the bonnet is not safely secured when the ve-
hicle is moving, stop the vehicle immediately and close the bonnet. Fail-
ure to do so could result in an accident.
 Engine oil
General notes
The engine comes with a special, multi-grade oil that can be used all year
round.
Because the use of high-quality oil is essential for the correct operation of
the engine and its long useful life, when topping up or changing oil, use on-
ly those oils that comply with VW standards.
The specifications (VW standards) set out in the following page should ap-
pear on the container 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 Pro-
gramme, be performed by a Technical Service or a specialised workshop.
The correct oil specifications for your engine are listed in the ⇒ page 254,
Oil properties.
Service intervals
Service intervals can be flexible (LongLife service) or fixed (dependent on
time/distance 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 service pro-
grammed. 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 developed which, depending on the
characteristics and individual driving profiles, enable the extension of the
oil change service (LongLife service intervals). 

WARNING
Only change the engine oil yourself if you have the specialist knowledge
required!
● Before opening the bonnet, read and observe the warnings
⇒ page 251.
● Wait for the engine to cool down. Hot oil may cause burn injuries.
● Wear eye protection to avoid injuries, such as acid burns, caused by
splashes of oil.
● When removing the oil drain plug with your fingers, keep your arm
horizontal to help prevent 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 stored in a safe place out of
the reach of children.
CAUTION
No additives should be used with engine oil. This could result in engine
damage. Any damage caused by the use of such additives would not be
covered by the factory warranty.
For the sake of the environment
● Because of the disposal problems, the necessary special tools and spe-
cialist 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 suitable container when draining the used oil. It must be large
enough to hold all the engine oil. Cooling system
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 boil-
ing 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. Topping up coolant
Top up coolant when the level is below the MIN (minimum)
mark.
Fig. 156 Engine com-
partment: Coolant expan-
sion tank cap
Checking coolant level
– Park the vehicle in a horizontal position.
– Switch the ignition off
– Read off the coolant level on coolant expansion 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 carefully
unscrew it to the left ⇒ 
. 

259
Checking and refilling levels
– Top up the coolant only if there is still coolant in the expansion
tank, otherwise you could damage the engine. If there is no
coolant in the expansion tank, do not continue driving. You
should obtain professional assistance ⇒ 
.
– If there is still some coolant in the expansion tank, top up to the
upper mark.
– Top up with coolant to the upper mark until the level becomes
stable.
– Screw the cap back on correctly.
Any loss of coolant fluid normally indicates a leak in the cooling system.
Take the vehicle straight to a specialised workshop to have the cooling sys-
tem 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 cooling system is under pressure. Do not unscrew the cap on the
coolant expansion tank when the engine is hot: risk of burns!
● The antifreeze and coolant fluid can be a health hazard. 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, even when
the ignition is switched off, the radiator fan may start up automatically,
and therefore there is a risk of injury.
CAUTION
Do not top up the expansion tank with coolant fluid if it is empty! Air could
enter the cooling system. In this case, stop driving. Seek specialist assis-
tance. Otherwise, there is a risk of engine damage. Brake fluid
Fig. 157 Engine com-
partment: brake fluid res-
ervoir, lid
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 warning light on the instrument panel display moni-
tors the brake fluid level ⇒ page 69.
In right-hand drive vehicles the brake fluid reservoir is on the other side of
the engine compartment.
Changing brake fluid
The regular intervals at which the brake fluid should be replaced are listed
in the Service Plan. We recommend you have the brake fluid replaced at a
SEAT Official Service, during an Inspection Service. 
