240Trailer towing
Trailer electric socket
The electric connection between vehicle and trailer is a 13-pin socket. If the
trailer plug has seven pins, an adapter cable must be used.
Trailer rear lights
Check the trailer rear lights to ensure they work correctly and remain legal.
Ensure that the trailer does not use more than the maximum power
⇒ page 237.
Trailer connected to the anti-theft alarm:
● When a vehicle comes from the factory fitted with an anti-theft alarm
and tow hitch.
● When the trailer is connected to the vehicle using the socket.
● When the vehicle and trailer electrical systems work correctly and are
not damaged.
● When the vehicle is locked using the vehicle key and the anti-theft alarm
is turned on.
When the vehicle is locked, the alarm is triggered when the electrical con-
nection between the vehicle and the trailer is removed.
Always turn off the anti-theft alarm system before connecting or disconnect-
ing a trailer. Otherwise, the tilt sensor may erroneously activate the alarm.
WARNING
Erroneous or unsuitable connection of electric cables may supply energy
to the trailer causing an anomaly in the vehicle electronics that could re-
sult in an accident with serious consequences.
● All work on the electrical system must be carried out only by a speci-
alised workshop.
● Never connect the trailer's electric system to the electrical connec-
tions of the rear lights or any other power sources.
CAUTION
Do not leave the trailer connected to the vehicle when parked; places on its
support wheel or its supports. For example, when changing the load or a
puncture, the vehicle will be pushed up or down. The force acting on the
tow hitch and the trailer could damage the vehicle or the trailer.
Note
● In case of a fault in the vehicle or trailer electrical system or in case of
problems with the anti-theft alarm system, have the system checked by a
specialised workshop.
● If the trailer accessories use energy from the socket when the engine is
stopped, the battery will be discharged.
● For technical reasons, trailers fitted with rear LED lights cannot be con-
nected to the anti-theft alarm system.
● If the vehicle battery is running low, the electrical connection with the
trailer is automatically cut.
● With the engine running, the electrical equipment on the trailer will con-
sume power. 
Loading the trailer
Trailer weight / drawbar load
The trailer weight is the load that the vehicle can pull ⇒ . The drawbar
load is the vertical weight of the trailer hitch on the tow hitch ball
⇒  page 244.
The figures for trailer weights and draw bar weights given on the data plate
of the towing bracket are for values of this model only. The correct figures
for your specific vehicle, which may be lower than these figures for the tow
hitch, are given in the registration documents. The instructions in the offi-
cial vehicle documents take precedence. 

254Vehicle maintenance and cleaning
The longer stains or dirt remain on the vehicle surfaces, especially the fab-
rics covering the padded upholstery, the more difficult it becomes to clean
and maintain them. If stains and dirt are left for a long time, it may be that
they are impossible to remove.
WARNING
Car care products may be toxic and hazardous. Using unsuitable car-care
products or, using them in the wrong way, may cause accidents, serious
injury, burns or intoxication.
● Keep your car-care products in their original containers.
● Read the instructions.
● Never keep car-care products in empty food containers, bottles or
other similar containers, other people may confuse them.
● Keep all car-care products out of the reach of children.
● Some products may give off harmful vapours during use. Therefore,
they should be used outdoors in well-ventilated places.
● Never use fuel, turpentine, engine oil, nail-varnish remover or any
other volatile product for washing, maintenance or cleaning. These are
toxic and highly flammable.
WARNING
Unsuitable maintenance and cleaning of vehicle components may impair
proper operation of safety equipment and cause serious injury.
● Maintain and clean vehicle components according to the manufactur-
er's instructions.
● Only use approved or recommended cleaning products.
CAUTION
● Cleaning products which contain solvents have a corrosive effect and
may damage the material irreparably.
● Stains and dirt containing aggressive substances or solvents attack the
material and may damage it irreparably, even when they are cleaned quick-
ly.
● Dirt and stains should not be allowed to dry and should be cleaned as
quickly as possible.
● In the case of stubborn stains, take the vehicle to a specialised work-
shop to avoid damage. 
Treating your upholstery
Checklist
To treat and maintain your seat upholstery, keep the following in mind ⇒ 
:
¥ Before entering the vehicle, close any Velcro fasteners that might
snag on the upholstery or trim fabric. Any open Velcro fasteners may
damage the trim or upholstery fabrics.
¥ To prevent damage, avoid direct contact between sharp decorative
objects and the upholstery and trim fabrics. Decorative objects in-
clude zips, rivets and rhinestones on clothing and belts.
¥ From time to time, clean the dust that gathers in the perforations,
folds and seams so that the surfaces of the seats are not damaged
by its abrasive effect.
¥ Make sure clothes are colour-fast to avoid them running and staining
the upholstery. This is especially important if the upholstery is light
in colour.

Retro-fitting of two-way radios
An exterior aerial is required for the use of two-way radios in the vehicle.
The retro-fitting of electrical or electronic appliances in the vehicle is sub-
ject to their approval for use in your vehicle. Under certain circumstances,
this could mean that your vehicle registration documents are no longer val-
id.
SEAT has approved your vehicle for use with two-way radios providing the
following conditions are observed:
●The exterior aerial must be mounted professionally.
● The maximum transmitting power is 10 watts.
An only external aerial is needed to give the equipment its optimal reach.
Check first with a qualified dealer if you wish to use a two-way radio with a
transmitting power of over 10 watts. The qualified workshops are familiar
with the technical options for installation. SEAT recommends visiting a Tech-
nical Service.
All legal requirements, together with the instructions for the use of two-way
radios must be observed.
WARNING
If the two-way radio is not securely fastened in position, it could be sent
flying around the vehicle in the event of sharp braking, sudden manoeu-
vres or accident, causing injury.
● While driving, two-way radios must be securely fastened in position,
outside the radius of action of the airbags, or safely stowed away.
WARNING
When using a two-way radio without a connection to an exterior aerial,
the maximum permitted levels of electromagnetic radiation may be ex-
ceeded. This is also the case if the aerial has not been correctly installed.
● You should only use a two-way radio inside the vehicle if it has first
been correctly connected to an exterior aerial.

Information stored by the control units
Your vehicle is fitted at the factory with a series of electronic control units
responsible for the engine and gearbox management. In addition, the con-
trol units supervise the performance of the exhaust gas system and the air-
bag systems.
Therefore, while the vehicle is being driven, these electronic control units
are continuously analysing the vehicle data. In the event of faults or devia-
tions from the theoretical values, only this data is stored. Normally, the
warning lamps on the instrument panel light up in the event of faults.
This data can only be read and analysed using special equipment.
The storing of the data allows specialised workshops to detect and repair
faults. Stored data may include:
● Data relating to the engine or the gearbox
● Speed
● Direction of travel
● Braking force
● Detection of seat belt
The vehicle control units never record conversations held by passengers in
the vehicle. 

Checking and refilling levels
WARNING (Continued)
– If you are using a metal fuel canister, the nozzle must always touch
the canister while it is being filled to avoid static electricity.
– Follow the legal requirements for the use, storage and transport of
spare fuel canisters.
– Insure that the fuel container complies with manufacturing stand-
ards, for example, ANSI or ASTM F852-86.
CAUTION
● Always remove any fuel spilled on the vehicle paintwork immediately to
avoid damage to the wheel housing, the tyre and vehicle paintwork.
● Refuelling a petrol engine with diesel or a diesel engine with petrol can
cause serious engine and fuel system damage; the resulting malfunctions
are not covered by the SEAT warranty. If you refuel with the wrong type of
fuel, never start the engine. This applies to even the smallest amount of the
wrong fuel. You should obtain professional assistance. With the engine run-
ning, the composition of the wrong fuel could significantly damage the fuel
system and the engine itself.
● In vehicles with a diesel engine, under no circumstances should you re-
fuel or drive with petrol, kerosene, heating oil or any other type of different
fuel. Other types of fuels could cause serious damage to the engine and to
the fuel supply system and the resulting problems are not covered by the
SEAT warranty.
For the sake of the environment
Fuels can contaminate the environment. Collect any spilt service fluids and
allow a professional to dispose of them.

Checking and refilling levels
● If, in exceptional circumstances, petrol with a lower octane rating to that
recommended is used, only use moderate engine speeds and a light throt-
tle. Avoid using full throttle and overloading the engine. Otherwise you may
damage the engine. Fill up with fuel of a suitable octane rating as soon as
possible.
● Do not refuel if the filler indicates that the fuel contains metal. LRP (lead
replacement petrol) fuels also contain high concentrations of metal addi-
tives. This could damage the engine!
● Just one full tank of leaded fuel would seriously impair the efficiency of
the catalytic converter and could damage it. 
Diesel
Diesel fuel
Diesel fuel must correspond to European standard EN 590 (In Germany,
EN 590 or DIN 51628).
The use of diesel fuel with a high sulphur percentage requires shorter serv-
ice intervals ⇒ Booklet Maintenance Programme ⇒ 
. Your Technical Serv-
ice will be able to tell you which countries have diesel with a high sulphur
content.
Do not mix fuel additives (thinners, or similar additives) with diesel fuel.
Winter-grade diesel
When using “summer-grade diesel fuel”, difficulties may be experienced at
temperatures below 0 °C (+32 °F) because the fuel thickens due to wax sep-
aration. For this reason, “winter-grade diesel fuel” is available in Germany,
for example, during the cold months. It can be used at temperatures as low
as -20 °C (-4 °F).
In countries with different climatic conditions, other types of diesel fuel are
available that are suitable to local temperatures. Technical Services and fill-
ing stations in the country concerned will inform you on the type of diesel
fuels available. A cold diesel engine makes more noise during winter temperatures than
summer temperatures. Furthermore, the exhaust fumes may turn slightly
bluish while the engine is heating. The quantity of exhaust gases will de-
pend on the outside temperature.
Filter pre-heater
Vehicles with a diesel engine are fitted with a fuel filter pre-heater. This en-
sures that the fuel system remains operational to approx. -24 °C (-11.2 °F),
provided you use winter-grade diesel which is safe to -15 °C (+5 °F).
However, if the fuel has waxed to such an extent that the engine will not
start at temperatures of under -24 °C (-11,2 °F), simply place the vehicle in a
warm garage or workshop for a while to heat up.
Auxiliary heater
Vehicles with a diesel engine may be fitted with an auxiliary heater. The
heater runs off the fuel from the fuel tank. On doing so, smells and steam
may be noticed outside the vehicle for a short period. This is normal and it
is not an indication of a fault in the vehicle.
Whenever there is little fuel in the tank (reserve), the auxiliary heater auto-
matically switches off.
WARNING
Never use start boosters. An aerosol start booster could explode or cause
a sudden rise in engine speed leading to engine damage and serious in-
jury. 

CAUTION
● The vehicle is not prepared for the use of biodiesel. Never, under any
circumstances refuel with biodiesel. It could damage the fuel system and
subsequently lead to engine faults!
● The addition of biodiesel to diesel by the diesel producer according to
Standard EN 590 or other equivalent (DIN 51628 in Germany, for example)
is authorised and causes no type of damage to the engine or the fuel
system.
● The diesel engine has been designed for to use diesel fuel exclusively.
Therefore, never use petrol, fuel oil or other unsuitable fuels. The composi-
tion of these fuels may significantly damage the fuel system and the en-
gine.
● The use of diesel fuels with a high sulphur percentage could considera-
bly reduce the service life of the diesel particulate filter. Your Technical Serv-
ice will be able to tell you which countries have diesel with a high sulphur
content. 
Information on fuel consumption
The consumption and emission values indicated do not refer to one specific
vehicle. They are only to be used to compare the values of the different ve-
hicle versions. The fuel consumption and CO 2 emissions of a vehicle not on-
ly depend on the effective use of fuel. They also depend on your driving
style and other non-technical factors.
Calculation of fuel consumption
Fuel consumption and emission values are determined according to the cur-
rent version of the 715/2007/EC or 80/1268/EEC regulation and are valid
for the vehicle kerb weight. The specifications do not refer to an individual
vehicle. Two measuring cycles are carried out on a rolling road test bed. The
test criteria are as follows:
Urban cycleMeasurement of the urban cycle starts with an engine cold
start. City driving is then simulated at between 0 and 50 km/
h.
Road cycleIn the road cycle simulation, the car undergoes frequent ac-
celeration and braking in all gears, as in normal everyday
driving. The road speed ranges from 0 to 120 km/h.
CombinedThe average combined consumption is calculated with a
weighting of around 37 % for the urban cycle and 63 % for
the road cycle.
CO 2 emis-
sions of the
combinationThe exhaust gases are collected during both driving cycles
to calculate carbon dioxide emissions (urban and road). The
gas composition is then analysed to evaluate the CO 2 con-
tent and other emissions.
Note
● The kerb weight may vary according to the vehicle equipment. This
could raise consumption and the CO 2 emissions slightly.
● In practice, consumption values could be different to the values calcula-
ted based on the 715/2007/EC or 80/1268/EEC regulations. 

Selective Catalytic Reduction* (AdBlue)
Introduction
The AdBlue fill level must be checked when the vehicle is being serviced
⇒ Booklet Maintenance Programme.
Additional information and warnings:
● Luggage compartment ⇒ page 126
● Fuel ⇒ page 271
● Wheels and tyres ⇒ page 297
● Accessories, parts replacement, repairs and modifications ⇒ page 261
WARNING
If the AdBlue fill level is too low, the vehicle may not restart after switch-
ing the ignition off. The emergency start or jump start will not be possi-
ble either!
● Top up with AdBlue at the latest 1000 km or 600 miles before it runs
out.
● Do not allow the AdBlue to run too low.
WARNING
AdBlue is an irritant, corrosive liquid that can cause injuries if it touches
the skin, eyes or respiratory organs.
● If AdBlue get in contact with eyes and skin, rinse for at least 15 mi-
nutes with plenty of water and seek medical help.
● If the AdBlue is swallowed, wash the mouth with plenty of water for at
least 15 minutes. Do not try to provoke vomiting unless recommended by
a Doctor. Seek medical advice immediately.
CAUTION
AdBlue damages surfaces such as painted vehicle parts, plastic, items of
clothing and carpets. Spilt AdBlue should be removed as quickly as possi-
ble using a damp cloth and plenty of cold water.
● If the AdBlue has crystallised, remove with warm water and a sponge. 
