WARNING (Continued)
● Never touch the radiator fan. It is temperature controlled and could
start automatically, even when the engine has been switched off and the
key removed from the ignition!
● Do not unscrew the cap on the expansion tank when the engine is
hot. If the coolant is hot, the cooling system will be pressurised!
● Protect face, hands and arms by covering the cap with a large, thick
cloth to protect against escaping coolant and steam.
● Always make sure you have not left any objects, such as cleaning
cloths and tools, in the engine compartment.
● If you have to work underneath the vehicle, you must use suitable
stands additionally to support the vehicle, there is a risk of accident!. A
hydraulic jack is insufficient for securing the vehicle and there is a risk of
injury.
● If any work has to be performed when the engine is started or with
the engine running, there is an additional, potentially fatal, safety risk
from the rotating parts, such as the drive belts, alternator, radiator fan,
etc., and from the high-voltage ignition system. You should also observe
the following points:
–Never touch the electrical wiring of the ignition system.
– Ensure that jewellery, loose clothing and long hair do not get trap-
ped in rotating engine parts. Danger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
– Never accelerate with a gear engaged without taking the necessary
precautions. The vehicle could move, even if the handbrake is ap-
plied. Danger of death.
● If work has to be carried out on the fuel system or on electrical com-
ponents, you must observe the following safety notes in addition to the
above warnings:
–Always disconnect the battery. The vehicle must be unlocked when
this is done, otherwise the alarm will be triggered.
– Do not smoke.WARNING (Continued)
– Never work near naked flames.
– Always have a fire extinguisher on hand.
CAUTION
When topping up service fluids, make sure not to mistake them. Using the
wrong fluids could cause serious malfunctions and engine damage!
For the sake of the environment
Service fluids leaks are harmful to the environment. For this reason you
should make regular checks on the ground underneath your vehicle. If you
find spots of oil or other fluids, have your vehicle inspected in a specialised
workshop. 

Engine oil General notes
The engine comes with a special, high quality, multi grade oil that can be
used in all seasons of the year except for those regions affected by extreme
cold.
As the use of good quality oil is necessary for the correct operation and long
service life of the engine, when it becomes necessary to replenish or
change the oil, always use an oil that complies to the 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 an Authorised Service Centre or a specialised
workshop.
The correct oil specifications for your engine are listed in ⇒ page 221, 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 QG1, this means that your vehicle has the LongLife service pro-
grammed. If it has the codes QG0 or QG2 the interval service is dependent
on time/distance travelled.
Flexible service intervals (LongLife*)
Special oils and processes have been developed which, depending on the
characteristics and individual driving profiles, allow to extend the oil
change service (LongLife service intervals).
Because this oil is essential for extending the service intervals, it
must only
be used observing the following indications:
● Avoid mixing it with oil for fixed service intervals.
● Only in exceptional circumstances, if the engine oil level is too low
⇒ page 221 and LongLife oil is not available, it is permitted to top up
(once) with oil for fixed service intervals ⇒  page 221 (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 al-
so appear in ⇒ page 221, Oil properties. In this case, your vehicle must be
serviced after a fixed interval of 1 year / 15 000 km (whatever comes first)
⇒ Booklet Maintenance Programme.
● In exceptional circumstances, if the engine oil level is too low
⇒ page 221 and you cannot obtain the oil specified for your vehicle, you
can put in a small quantity of oil conforming to the specification ACEA A2 or
ACEA A3 (petrol engines) or ACEA B3 or ACEA B4 (diesel engines) (up to 0.5
l). 

Checking and refilling levels
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 die-
sel engines equipped with particulate filter. Using other types of oil will
cause a higher soot concentration and reduce the life of the DPF. Therefore:
● Avoid mixing this oil with other engine oils.
● Only in exceptional circumstances, if the engine oil level is too low
⇒ page 221 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). 

Engine oil additives
No type of additive should be mixed with the engine oil. The deterioration
caused by these additives is not covered by the warranty.
Note
Before a long trip, we recommend finding an engine oil that conforms to the
corresponding VW specifications and keeping it in the vehicle. This way, the
correct engine oil will always be available for a top-up if needed. 
Checking the engine oil level
The engine oil dipstick indicates the level of the oil.

222Checking and refilling levels
–Pull out the dipstick. Wipe the dipstick with a clean cloth and
insert it again, pushing it in as far as it will go.
– Then pull it out once more and check the oil level ⇒ fig. 144.
Top up with engine oil if necessary.

Depending on how you drive and the conditions in which the vehicle is
used, oil consumption can be up to 0.5 l/1000 km. Oil consumption is likely
to be higher for the first 5000 km. For this reason the engine oil level must
be checked at regular intervals, preferably when filling the tank and before
a journey.
WARNING
Any work carried out in the engine compartment or on the engine must
be carried out cautiously.
● When working in the engine compartment, always observe the safety
warnings ⇒ page 217.
CAUTION
If the oil level is above the area A do not start the engine. This could result
in damage to the engine and catalytic converter. Contact an Authorised
Service Centre. 

Before opening the bonnet, read and observe the warnings ⇒ 
in
Safety instructions on working in the engine compartment on
page 217.
– Unscrew cap from oil filler opening ⇒ fig. 145.
– Top-up oil in small amounts, using the correct oil.
– To avoid over-filling with engine oil, you should top-up using
small quantities, wait a while and check the oil level before
adding any more oil.
– As soon as the oil level is in area B
, carefully close the cap.
The position of the oil filler opening is shown in the corresponding engine
compartment illustration ⇒ page 273. 

Checking and refilling levels
Engine oil specification ⇒ page 220.
WARNING
Oil is highly inflammable! Ensure that no oil comes into contact with hot
engine components when topping up.
CAUTION
If the oil level is above the area A do not start the engine. This could result
in damage to the engine and catalytic converter. Contact a specialised work-
shop.
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. 
Changing engine oil
The engine oil must be changed at the intervals given in the
service schedule. We recommend that you have the engine oil changed by an Authorised
Service Centre.
The oil change intervals are shown in the Maintenance Programme.
WARNING
Only change the oil yourself if you have the specialist knowledge re-
quired!
● Before opening the bonnet, read and observe the warnings
⇒ page 217, Safety instructions on working in the engine compartment.
● Wait for the engine to cool down. Hot oil may cause burn injuries.
● Wear eye protection to avoid injuries 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 an Authorised Service Centre.
● 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. 

Coolant
Coolant specifications
Coolant is a mixture of water and at least 40% coolant addi-
tive. The cooling system must be filled with a mixture of water and at least 40 %
of our coolant additive G 12+ or an additive with the specification TT-VW
774 F (it is dyed purple). This mixture provides the necessary freeze protec-
tion down to -25°C and protects the alloy parts of the cooling system
against corrosion. It also prevents scaling and raises the boiling point of the
coolant.
The concentration of coolant must always be at least 40% - even if freeze
protection is not required.
If greater freeze protection is required in very cold climates, the proportion
of the antifreeze additive G 12+ can be increased. However, the percentage
of coolant additives should not exceed 60%, as this would reduce the
freeze protection. It would also reduce the cooling effect. A mixture with
60% additive will give antifreeze protection to approx. -40°C.
WARNING
● The coolant additive is toxic. There is a toxic risk. Always keep the
coolant additive in the original container which should be stored out of
the reach of children. The same applies to coolant which you have
drained off.
● The coolant additive G 12+ must be added in sufficient quantities to
provide anti-freeze protection at the coldest ambient temperatures that
can be expected. At extremely cold outside temperatures, the coolant
could freeze, causing the vehicle to breakdown. As the heater would not
work either, there is a risk of freezing to death.
CAUTION
● Other additives may give considerably inferior corrosion protection. The
resulting corrosion in the cooling system can lead to a loss of coolant, caus-
ing serious damage to the engine.
● The coolant additive G 12+ (purple) can be mixed with the additive G 12
(red) or G 11. Never mix G12 (red colour) with G 11. 
Checking the coolant level and topping up 
The correct coolant level is important for fault-free function-
ing of the engine cooling system.

Brake fluid Checking the brake fluid level
The brake fluid is checked at the intervals given in the serv-
ice schedule.
Fig. 151 In the engine
compartment: Brake fluid
reservoir cover
– Read off the fluid level at the transparent brake fluid reservoir. It
should always be between the “MIN” and “MAX” marks.
The position of the brake fluid reservoir is shown in the corresponding en-
gine compartment illustration ⇒ page 273. The brake fluid reservoir has a
black and yellow cap.
The brake fluid level drops slightly when the vehicle is being used as the
brake pads are automatically adjusted as they wear.
However, if the level goes down noticeably in a short time, or drops below
the “MIN” mark, there may be a leak in the brake system. A display on the
instrument panel will warn you if the brake fluid level is too low ⇒ page 77.
WARNING
Before opening the bonnet to check the brake fluid level, read and ob-
serve the warnings ⇒ page 217.

Changing the brake fluid
The Maintenance Programme indicates the brake fluid
change intervals. We recommend that you have the brake fluid changed by an Authorised
Service Centre.
Before opening the bonnet, please read and follow the warnings ⇒ 
in
Safety instructions on working in the engine compartment on page 217 in
section “Safety notes for working in the engine compartment”.
Brake fluid absorbs moisture. In the course of time, it will absorb water from
the ambient air. If the water content in the brake fluid is too high, the brake
system could corrode. This also considerably reduces the boiling point of
the brake fluid. Heavy use of the brakes may then cause a vapour lock
which could impair the braking effect.
It is important that you use only brake fluid compliant with US standard
FMVSS 116 DOT 4. We recommend the use of Genuine SEAT brake fluid.
WARNING
Brake fluid is poisonous. Old brake fluid impairs the braking effect.
● Before opening the bonnet to check the brake fluid level, read and ob-
serve the warnings ⇒ page 217. 
