13Earth for pin 9 Trailer power socket
The v
ehic

le is fitted with a 13-pole power
socket for the electrical connection between
the trailer and the vehicle. With the engine
running, electrical devices on the trailer re-
ceive power from the electrical connection
(pin 9 and pin 10 of the trailer power socket).
If the system detects that a trailer has been
connected electrically, the electrical equip-
ment on the trailer will receive voltage
through this connection (pins 9 and 10). Pin
9 has a permanent live. This powers, for ex-
ample, the trailer's interior lighting. Electrical
devices such as a fridge in a caravan only re-
ceive electrical power if the engine is running
(through pin 10).
To avoid overloading the electrical system,
you cannot connect the ground wires of pin
3, pin 11 or pin 13.
If the trailer has a 7-contact connector , you
will need to use an adapter cable. In this case
the function corresponding to pin 10 will not
be available. Tow rope
The to
w r

ope must always be securely fixed
to the towing vehicle and loose enough so
that the vehicle can handle turns smoothly.
However, make sure that the cable does not
rub on the ground while driving.
Trailer rear lights
Always check the trailer's rear lights to en-
sure they are working correctly and that they
comply with the relevant safety regulations.
Make sure that the maximum permissible
power that can be absorbed by the trailer is
not exceeded ››› page 276.
Connection to the anti-theft system
The trailer is included in the anti-theft system
if the following conditions are met: ● If the vehicle is factory-equipped with an
anti-theft al
arm and towing bracket.
● If the trailer is electrically connected to the
tow
ing vehicle through the trailer power
socket.
● If the electrical systems of the vehicle and
trail
er are in perfect condition and have no
faults or damage.
● If the vehicle is locked with the key and the
anti-theft al
arm is activated.
When the vehicle is locked, the alarm is trig-
gered if the electrical connection with the
trailer is cut off.
278

Towing bracket device*
Before hitching or unhitching a trailer, always
t urn off
the anti-thef
t alarm. Otherwise, the
tilt sensor could cause the alarm to go off.
Trailers with LED rear lights
For technical reasons, trailers fitted with LED
rear lights cannot be connected to the anti-
theft alarm system.
When the vehicle is locked, the alarm does
not go off when the electrical connection with
the trailer is cut if it has rear lights with light-
emitting diodes.
If the Eco driving profile was selected when
hitching the trailer, this will automatically
switch to the Normal profile. If the system
cannot detect the attached trailer or if the
towing bracket has been retrofitted by an au-
to repair shop other than SEAT, you must
manually select the Normal profile before you
start driving with a trailer attached. To recon-
nect the Eco profile once the trailer has been
unhitched, switch the ignition off and back
on once. WARNING
If the cables are improperly or incorrectly
connect ed, it

may lead to an excessive
amount of current supplied to the trailer,
which can cause abnormalities in the entire
vehicle electronic system, as well as acci-
dents and serious injuries. ●
Ens ur

e that any repairs that need to be car-
ried out on the electrical system are carried
out by a specialised workshop.
● Never connect the trailer's electric system
directly t
o the electrical connections of the
tail lights or any other power sources. WARNING
Contact between the pins of the trailer power
soc ket

can cause short circuits, overloading
of the electrical system or failure of the light-
ing system, and consequently can cause acci-
dents and serious injuries.
● Never connect the pins of the trailer power
socket
to each other.
● Make sure any work on bent pins is carried
out by
a specialised workshop. CAUTION
Do not leave the trailer connected to the vehi-
cl e when p

arked; place it on its support
wheel or its supports. If the vehicle rises or
falls due, for example, to a variation of the
load or a burst tyre, increased pressure will
be placed on the towing bracket and the trail-
er, and both the vehicle and the trailer can be
damaged. Note
● In ca se of

malfunctioning of the electrical
systems of the vehicle or trailer, as well as of the anti-theft system, have these checked out
by
a s

pecialised workshop.
● If the trailer accessories consume energy
through the pow
er socket to the trailer and
the engine is turned off, the battery will dis-
charge.
● If the vehicle battery is running low, the
electrica
l connection with the trailer will be
automatically cut. Loading a trailer

If the automatic filler nozzle is operated cor-
rectly, it will switch itself off as soon as the
fuel tank is “full”. Do not try to put in more
fuel after the nozzle cuts out, as this will fill
the expansion chamber in the fuel tank.
The correct fuel grade for your vehicle is giv-

Ob ser
ve legislation governing the use,
storage and carrying of a spare fuel canister
in the vehicle.
● For safety reasons we do not recommend
carry
ing a spare fuel canister in the vehicle.
In an accident the canister could be damaged
and could leak.
● If, in exceptional circumstances, you have
to carr
y a spare fuel canister, please observe
the following points:
– Never fill fuel into the spare fuel canister
if it is inside or on top of the vehicle. An
electrostatic charge could build up during
filling, causing the fuel vapour to ignite.
Danger of explosion. Always place the
canister on the ground to fill it.
– Insert the filling nozzle as far as possible
into the spare fuel canister.
– If the spare fuel canister is made of met-
al, the filling nozzle must be in contact
with the canister during filling. This
helps prevent an electrostatic charge
building up.
– Never spill fuel in the vehicle or in the
luggage compartment. Fuel vapour is ex-
plosive. Risk of fatal accident! CAUTION
● If an y

fuel is spilt onto the vehicle, it
should be removed immediately. It could oth-
erwise damage the paintwork.
● Never run the tank completely dry. An irreg-
ular f
uel supply could cause misfiring. As a
result, unburnt fuel could enter the exhaust
system and damage the catalytic converter.
● When filling the fuel tank after having run it
compl
etely dry on a vehicle with a diesel en-
gine, the ignition must be switched on for at
least 30 seconds before starting the engine.
When you then start the engine it may take
longer than normal (up to one minute) to
start firing. This is because air needs to be
bled from the fuel system while starting. For the sake of the environment
Do not overfill the fuel tank, it may cause the
fuel t

o overflow if it becomes warm. Note
There is no emergency mechanism for the
manua l

release of the fuel tank flap. If neces-
sary, request assistance from specialised per-
sonnel. Note
Diesel vehicles are fitted with a protective de-

● If the pump nozzle is worn, damaged, or if
it is
very small, it is possible that it will not
be able to open the protective device. Before
trying to insert the pump nozzle by turning it,
try a different pump or request specialist
help.
● If you fill the tank from a reserve fuel canis-
ter, the pr
otective device will not open. One
way to resolve this is to pour the fuel in very
slowly. Fuel

Checking and refilling levels
We recommend the use of diesel
f uel which
complies to European standard EN 590. If
diesel fuel which meets European standard
EN 590 is not available, the Cetane number
(CZ) must, at minimum, be 51. If the engine
is equipped with a particulate filter, the sul-
phur content of the fuel must be below 50
parts per million.
Winter-grade diesel
Summer fuel becomes thicker in winter and it
is more difficult to start the engine. For this
reason, petrol stations in some countries al-
so offer winter diesel with improved fluidity
when cold (winter-grade diesel).
Water in the fuel filter 1)
If your vehicle has a diesel engine and is
equipped with a fuel filter with a water sepa-
rator, the instrument panel may display the
following warning:  Water in the
fuel filter. If this is the case, take the
vehicle to a specialised workshop so that
they can drain the fuel filter. CAUTION
● The v ehic

le is not designed for the use of
FAME fuel (biodiesel). The fuel system would
be damaged if you used biodiesel. ●
Do not mi x

fuel additives, the so-called
“thinners”, petrol or similar additives with
diesel fuel.
● If poor-quality diesel fuel is used, it may be
neces
sary to drain the fuel filter more fre-
quently than is specified in the Maintenance
Programme. We recommend having this done
by a specialised workshop. If water is allowed to collect in the filter, this can cause engine
performance problems. AdBlue

Gener a
l

notesThe engine comes with a special, multi-grade
oi
l
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 Mainten

ance Programme, be per-
formed by a technical service or specialised
workshop.
The correct oil specifications for your engine
are listed in the ›››
 page 58, Engine oil
specifications.
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
service 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 e
xceptional circumstances, if the
engine oil level is too low ››› page 301,
Checking engine oil level and LongLife oil is
not available, it is permitted to top up (once)
with oil for fixed service intervals
›››  page 58 (up to a maximum of 0.5 li-
tres).
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 58, Engine oil specifications
. In
this case, your vehicle must be serviced after
a fixed interval of 1 year/15,000 km (10,000
miles)(whatever comes first) ››› Booklet
Maintenance Programme.
● In exceptional circumstances, if the engine
oil l
evel is too low ››› page 301, Checking en-
gine oil level and you cannot obtain the oil
specified for your vehicle, you can add a
small quantity of oil conforming to the speci-
fication ACEA A2 or ACEA A3 (petrol engines)
or ACEA B3 or ACEA B4 (diesel 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.

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
