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

Operation
To promote safety while driving, SEAT recom-
mend s
m
aking the most of the maximum ver-
tical load technically permissible on the cou-
pling device ››› page 273. An insufficient ver-
tical load has a negative influence on the be-
haviour of both the vehicle and trailer.
The vertical load increases the weight on the
rear axle, reducing the vehicle's carrying ca-
pacity.
Gross combination weight of the towing ve-
hicle and trailer
The gross combination weight is the actual
weight of the loaded vehicle plus the actual
weight of the loaded trailer.
In some countries trailers are classified into
distinct categories. SEAT recommends ob-
taining information from a specialised work-
shop regarding which type of trailer is most
suitable for your vehicle.
Trailer loading
The weight of the towing vehicle and trailer
must be balanced. In order to do this, the
load must be as close as possible to the max-
imum vertical load technically permissible on
the coupling point, and it must be evenly dis-
tributed between the back and front of the
trailer:
● Distribute loads in the trailer so that heavy
obj
ects are as near to the axle as possible or
above it. ●
Secure the tr
ailer load properly.
Tyre pressure
Set the tyre pressure of the trailer tyres in ac-
cordance with the trailer manufacturer's rec-
ommendations.
When towing a trailer, inflate the tyres of the
towing vehicle with the maximum allowable
pressure ››› page 308. WARNING
If the maximum permissible axle weight, the
max imum lo
ad technically permissible on the
coupling point, the maximum authorised ve-
hicle weight or the gross combination weight
of the towing vehicle and trailer are excee-
ded, accidents and serious injuries may oc-
cur.
● Never exceed the values indicated!
● The actual weight on the front and rear
axle
s must never exceed the maximum per-
missible axle weight. The weight on the front
and rear axles must never exceed the maxi-
mum permissible weight. WARNING
A shift in weight could jeopardize the stabili-
ty and sec urity
of the towing vehicle and
trailer, which could lead to accidents and se-
rious injuries.
● Always load the trailer correctly. ●
Alw a
ys secure the load properly using belts
or straps that are suitable and in good condi-
tion. Driving with a trailer
Adjusting the headlights
When to
w
ing a trailer, the front part of the ve-
hicle could lift up, and if the dipped beams
are on, this could dazzle other drivers. Use
the headlight range control to lower the cone
of light. If you do not have headlight range
control, have the headlights adjusted by a
specialised workshop.
Special characteristics of driving with a trail-
er
● If your trailer has an overru
n brake, brake
gently at first and then rapidly. This will pre-
vent the jerking that can be caused by the
locking of trailer wheels.
● Due to the gross combination weight of the
tow
ing vehicle and trailer, the braking dis-
tance increases.
● When going down a slope, go into a lower
gear (if
using a manual gearbox or the tip-
tronic automatic gearbox mode) to take ad-
vantage of the braking power provided by the
engine. Otherwise, the braking system could
overheat and even fail.

Refuelling Read the additional information carefully
›› ›
page 56
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-
en on a sticker on the inside of the fuel tank
flap. Further notes on fuel can be found at
››› page 293.
The capacity of your vehicle's fuel tank is giv-
en in ›››

Fuel is highly flammable and can cause seri-
ous b
urns and other injuries.
● When refuelling, turn off the engine, the
auxili
ary heater ››› page 177 and turn off the
ignition for safety reasons.
● Do not smoke when filling the fuel tank or a
canis
ter. Naked flames are forbidden in the
vicinity due to the risk of explosion. 292
Checking and refilling levels
●
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-
vic e th
at prevents the insertion of the wrong
fuel hose 1)
. It is only possible to refuel with
Diesel nozzles.
● 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

10 % (E10). The types of petrol are differenti-
at ed b
y
their octane rating (RON).
The following titles appear on the corre-
sponding adhesive on the fuel tank flap:
Super unleaded 95 octane or normal 91 oc-
tane unleaded petrol
We recommend you use super 95 octane pet-
rol. If this is not available: normal 91 octane
petrol, with a slight decrease in power.
Super unleaded petrol with a minimum of 95
octanes
You should use super petrol with a minimum
of 95 octanes.
If super is not available, in an emergency you
may refuel with normal 91 octane petrol. In
this case only use moderate engine speeds
and a light throttle. Refuel with super as soon
as possible.
Super unleaded 98 octane or super 95 oc-
tane unleaded petrol
We recommend you use super plus 98 octane
petrol. If this is not available: super 95 oc-
tane petrol, with a slight decrease in power.
If super is not available, in an emergency you
may refuel with normal 91 octane petrol. In
this case only use moderate engine speeds
and a light throttle. Refuel with super as soon
as possible. Petrol additives
The quality of the f
uel influences the behav-
iour, power and service life of the engine.
This is why the petrol you use should carry
suitable additives already included by the
petrol industry, free of metals. These addi-
tives will help to prevent corrosion, keep the
fuel system clean and prevent deposits from
building up in the engine.
If good-quality petrol with metal-free addi-
tives is not available or engine problems
arise, the necessary additives must be added
when refuelling ››› .
Not al
l
petrol additives have been shown to
be effective. The use of unsuitable petrol ad-
ditives may cause significant damage to the
engine and the catalytic converter. Metal ad-
ditives should never be used. Metal additives
may also be contained in petrol additives for
improving anti-detonation ratings or octane
ratings ››› .
S EA
T r
ecommends “genuine Volkswagen
Group Fuel Additives for petrol engines”.
These additives can be bought at SEAT deal-
ers, where information on how to use them
can also be obtained. CAUTION
● Do not r ef
uel if the filler indicates that the
fuel contains metal. LRP ( lead replacement
petrol) fuels contain high concentrations of metal additives. Using them may damage the
engine!
● Nev er r
efuel with fuels containing a large
proportion of
ethanol (for example, E50, E85).
This could damage the fuel system.
● Just filling one full tank of leaded fuel or
fuel c
ontaining other metal additives would
seriously impair the efficiency of the catalytic
converter.
● Only use fuel additives that have been ap-
prov
ed by SEAT. Octane boosting or anti-
knock additives may contain metal additives
that could seriously damage the engine or
the catalytic converter. These additives must
not be used.
● High engine speed and full throttle can
damag
e the engine when using petrol with an
octane rating lower than the correct grade for
the engine. Note
● You m a
y use petrol with a high octane num-
ber than the one recommended for your en-
gine.
● In those countries where unleaded petrol is
not avai
lable, you may refuel with a fuel with
a low lead content. Diesel fuel
Please note the information on the inside of
the f
uel
t
ank flap.
294
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
