Information on AdBlue
In vehicles with Selective Catalytic Reduction, a special urea solution
(AdBlue) is injected into the exhaust gas system in front of the catalytic
converter to reduce nitrogen oxide emissions.
The consumption of AdBlue depends on individual driving style, the temper-
ature at which the system operates and the outside temperature where the
vehicle is driven.
AdBlue is kept in an independent tank in the vehicle and should be refilled at
an official supplier. The AdBlue tank holds about 17 litres.
A message will be displayed on the instrument panel around 2400 km before
the next service to indicate that AdBlue must be refilled Ÿpage 302. If you
ignore this message and do not refill, you will be unable to start the engine
afterwards Ÿpage 300.
SEAT recommends contacting a specialist workshop. If you are unable to visit
a qualified specialist workshop, you should temporarily refill with a minimum
of 10.0 litres of AdBlue. Only refill using AdBlue expressly approved by SEAT.When the indicators
b and > light simultaneously, there is a fault. SEAT
recommends visiting the closest qualified workshop.
AdBlue
® is a registered trademark in the US, Germany, the European Union
and other countries belonging to the German automobile industry ("Verband
der Automobilindustrie e. V.", VDA).

xStop the engine and wait a few minutes for the oil to drain back into the
sump. When the engine has cooled down, immediately check the oil level and
top up if necessary.
xOpen the bonnet ’ Ÿpage 304.
xThe engine oil filler opening can be recognised by the symbol E on the
cap Ÿpage 310, fig. 176 and the dipstick by its coloured handle.
Checking the engine oil level
xPull out the dipstick and wipe it on a clean cloth.
xReplace the dipstick, pushing it in as far as it will go. If the dipstick has a
mark, when you reintroduce it this mark should slot into the corresponding
groove located on the upper end of the tube.
xRemove the dipstick again and check the engine oil level Ÿtable on
page 311.
xAfter reading the oil level, replace the dipstick in the tube completely.
Engine oil topping up ranges
Adding oil after checking the level
Only add engine oil in small quantities and in steps.
xUnscrew the cap from engine oil filler opening on the cylinder head
Ÿpage 310, fig. 176. If you are not sure where the cap is, request help from
a specialist.
xOnly refill using engine oil expressly approved by SEAT and in small quan-
tities (not more than 0.5 L or 1/2 a quarter of a gallon at a time) Ÿpage 310.
xTo 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.
xCheck the oil level before adding any more oil. Do not top up with too
much engine oil Ÿ.
xWhen the oil level is in at least the Ÿpage 310, fig. 175 zone, insert
the dipstick into the tube fully to avoid engine oil escaping when the engine
is running.
xAfter topping up the oil, ensure that the cap is screwed on to the filler
mouth 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.
xAlways ensure that after topping of oil, the engine oil filler cap is
correctly tightened. This will avoid engine oil spilling onto hot engine parts
when the engine is running.
Caution
xIf the oil level is above the area Ÿpage 310, fig. 175 do not start the
engine. You should obtain professional assistance. Otherwise catalytic
converter and engine damage may occur.
xWhen refilling or changing service liquids, ensure that you put the liquids
into the right tank. Making a mistake when refilling could cause serious
malfunctions and damage the engine!
For the sake of the environment
The oil level must never be above area Ÿpage 310, fig. 175 . Otherwise
oil can be drawn in through the crankcase breather and escape into the
atmosphere via the exhaust 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.
Depending on driving style and the conditions of use, the consumption of
engine oil can reach 1 litre every 2,000 km (one quarter of a gallon every
1,200 miles); for new vehicles, this could be higher for the first 5,000 km
(3,000 miles). 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, when towing a trailer or climbing mountain
passes, the oil level should preferably be kept within area Ÿpage 310,
fig. 175 .
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 qualified workshop to have
the engine oil and filter changed. SEAT recommends visiting a qualified work-
shop.
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:
xWear eye protection.
xAlways wait until the engine has completely cooled to avoid being
burned.
xAlways 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.
xUse a suitable and large enough container to collect all of the used oil
in the engine.
xNever collect engine oil in empty food containers, cans, bottles and
other containers as not all people are able to identify engine oil.
xOil 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.

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 Ÿ! Have
the work carried out by a qualified workshop if you are uncertain. SEAT recom-
mends visiting a qualified workshop.

WARNING
Engine coolant is toxic!
xOnly keep engine coolant in its original container, tightly shut and in a
safe place.
xNever store engine coolant in empty food containers or bottles as other
people may accidentally drink it.
xAlways keep engine coolant out of reach of children.
xEnsure that the proportion of engine coolant additive corresponds to
the lowest outside temperature to which the vehicle will be exposed.
xIf 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, passengers 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.
Coolant temperature warning lamp and gauge
When driving normally, the needle will remain in the middle area. The temper-
ature may also rise when the engine is working hard, especially at high
outside temperatures and so the indicator will move quite far to the right-
hand side.
Several warning and control lamps should light up for a few seconds when
the ignition is switched. This signals that the lamp is working properly. They
will switch off after a few seconds.
