Fitting a towing bracket•Driving with a trailer involves an extra effort for the vehicle. Therefore,
before fitting a towing bracket, please contact an Authorised Service Centre
to check whether your cooling system needs modification.•Submit to the legal requirements in your country (e.g. the fitting of a sepa-
rate warning lamp).•Certain vehicle components, e.g. the rear bumper, must be removed and
reinstalled. The towing bracket securing bolts must be tightened using a
torque wrench, and an electrical socket must be connected to the vehicle's
electrical system. The above-mentioned require specialized knowledge and
tools.•Figures in the illustration show the elevation value and the attachment
points which must be considered if you are retrofitting a towing bracket.WARNING
Towing brackets should be fitted by specialists.

Engine oilGeneral notesWe recommend that the oil change should be performed by an Authorised
Service Centre or a qualified workshop, according to the Maintenance
Program. The correct oil specifications for your engine are listed in the
⇒page 229,
“Oil properties”.
Check that the specifications quoted (VW standards) appear on the container
either singly or in combination with other specifications.
Flexible maintenance intervals (Extended Service Intervals*)
Special lubricating oils have been de ve lop
ed in the framework of the SEAT
Booklet “Extended Se rvice Intervals” Maintenance Programme
⇒ page 229.
This typ

e of oil must be used if you intend to take advantage of the prolonga-
tion of the maintenance intervals in the framework of the “Extended Service
Intervals” program.
•Do not mix the LongLife oil with oil intended for fixed service intervals, as
the requirements for the extended service intervals are then no longer guar-
anteed.•Only in exceptional circumstances, if the engine oil level is too low
⇒ page 230 and LongLife oil is not available, it is permitted to top up (once)
with oil for fixed service intervals ⇒ page 229 (up to a maximum of 0.5
litres).
Fixed service intervals*
If “Extended Service Intervals” are not applied to your vehicle, you can use
oils for fixed service intervals ⇒ page 229. In this case, your vehicle must be
serviced after a fixed interval of 1 year / 15,000 km (10,000 miles) (see the
Maintenance Program).•In exceptional circumstances, if the engine oil level is too low
⇒ page 230 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 0.5l).
Vehicles with diesel particulate filter*
The Maintenance Program states whether your vehicle is fitted with a diesel
particulate filter.

Winter operations
The battery is drained more in cold weather, which means that the starting
power is reduced. For this reason, have the battery checked and charged if
necessary before the start of winter.
Replacing the battery
A replacement battery
must have the same capacity, voltage and current
rating. It must also have the same dimensions as the original, factory-fitted
battery and have sealed caps. The SEAT batteries which have been specially
developed fulfil the maintenance, performance and safety specifications for
your vehicle.
We recommend you use maintenance-free batteries.
WARNING
•All work on batteries requires specialist knowledge. If work is required
on the battery, this should be performed by a Technical Service or
specialist garage. Danger of caustic burns and explosion!•The battery must not be opened. Never try to change the battery's
liquid level. Explosive gas is released from the battery that could lead to an
explosion.Caution
•The battery holder and clamps must always be correctly secured.•Before starting any work on the battery, always observe the warnings
listed under ⇒.For the sake of the environment
 Batteries contain toxic substances including sulphuric acid and lead.
Therefore, they must be disposed in line with environmental regulations and
must not be disposed of with ordinary household waste. Make sure discon-
nected batteries cannot tip over. Sulphuric acid could be spilt!
Important safety warnings for handling a car batteryThe battery is located at the back of the engine compartment ⇒ page 295.
WARNING
Always be aware of the danger of injury and chemical burns as well as the
risk of accident or fire when working on the battery and the electrical
system:•Wear eye protection. Protect your eyes, skin and clothing from acid and
particles containing lead.•Battery acid is very corrosive and caustic. Wear protective gloves and
eye protection. Do not tilt the batteries. This could spill acid through the
vents. Rinse battery acid from eyes immediately for several minutes with
clear water. Then seek medical care immediately. Neutralize any acid
splashes on the skin or clothing with a soapy solution, and rinse off with
plenty of water. If acid is swallowed by mistake, consult a doctor immedi-
ately.•Fires, sparks, naked lights and smoking are prohibited. When handling
cables and electrical equipment, avoid causing sparks and electrostatic
charge. Never short the battery terminals. High-energy sparks can cause
injury.

Technical Data
For the sake of the environment
Old tyres must be disposed of according to the laws in the country concerned.
Note
•For technical reasons, it is not generally possible to use the wheels from
other vehicles. This can also apply to wheels of the same model. The use of
wheels or tyres which have not been approved by SEAT for use with your
model may invalidate the vehicle's type approval for use on public roads.•If the spare tyre is not the same as the tyres that are mounted on the
vehicle - for example with winter tyres - you should only use the spare tyre for
a short period of time and drive with extra care. Refit the normal road wheel
as soon as possible.Wheel bolts
Wheel bolts must be tightened to the correct torque.The design of wheel bolts is matched to the rims. If different wheel rims are
fitted, the correct wheel bolts with the right length and correctly shaped bolt
heads must be used. This ensures that wheels are fitted securely and that the
brake system functions correctly.
In certain circumstances, you may not use wheel bolts from a different car -
even if it is the same model ⇒page 220.
After the wheels have been changed, the tightening torque of the wheel bolts
s ho uld b e ch ecke d as so on as possi ble wi th a to rq ue wre nch ⇒ . The tight-
ening torque for steel and alloy wheels is 120 Nm.
WARNING
If the wheel bolts are not tightened correctly, the wheel could become
loose while driving. Risk of accident.•The wheel bolts must be clean and turn easily. Never apply grease or oil
to them.•Use only wheel bolts which belong to the wheel.•If the torque of the wheel bolts is too low, they could loosen whilst the
vehicle is in motion. Risk of accident! If the tightening torque is too high,
the wheel bolts and threads can be damaged.Caution
The prescribed torque for wheel bolts for steel and alloy wheels is 120 Nm.Winter tyres
Winter tyres will improve the vehicles handling on snow and
ice.In winter conditions winter tyres will considerably improve the vehicles
handling. The design of summer tyre s (width, rubber compound, tread
pattern) gives less grip on ice and snow.
Winter tyres must be inflated to a pressure 0.2 bar higher than the pressures
specified for summer tyres (see sticker on tank flap).
Winter tyres must be fitted on all four wheels.
Information on permitted winter tyre sizes can be found in the vehicle's regis-
tration documents. Use only radial winter tyres. All tyre sizes listed in the
vehicle documentation also apply to winter tyres.

Before replacing the jack in the storage bin, wind down the arm of the jack as
far as it will go.
Some of the tools listed are only provided in certain models or are optional
extras.WARNING
•Do not use the hexagonal socket in the screwdriver handle to tighten
the wheel bolts, as with this it is not possible to tighten the bolts to the
required torque. Risk of accident.•The jack supplied by the factory is only designed for changing wheels
on this model. On no account attempt to use it for lifting heavier vehicles
or other loads. Risk of injury.•Never start the engine when the vehicle is raised. Failure to do so could
result in an accident.•If work is to be carried out underneath the vehicle, this must be secured
by suitable stands. Otherwise, there is a risk of injury.
Tyre mobility system
The tyre mobility system is stor ed under the floor panel in the
luggage compartment.– Take hold of the handle and fold back the floor panel in the
luggage compartment.
– Take out the tyre mobility system.Your vehicle is equipped with a Tyre Mobility System in case of a puncture.
The tyre mobility system consists of a container with sealing compound and
a compressor to generate the required tyre pressure.
Instructions for using the sealant compound and the compressor are
included with the sealant can.

Spare steel rim wheel
The spare steel rim wheel is carried in the wheel well under
the floor panel in the luggage compartment. It is only
intended for temporary use over short distances.Taking out the spare wheel
–Turn the plastic knob ⇒ fig. 194 anti-clockwise.
– Take out the spare wheel.
Securing the defective wheel in the spare wheel well
– Place wheel in spare wheel well in the luggage compartment.
– Secure wheel by turning plastic knob clockwise.
– Replace the floor panel before closing the boot lid.
Your vehicle can be equipped with a steel spare wheel at the factory. The
spare wheel does not usually meet the same performance standards as the
wheels fitted on the vehicle because of the wheel/tyre dimensions, rubber
composition, tread pattern, etc. Therefore, note the following restrictions:•The spare steel rim wheel is designed only for your vehicle model. Do not
attempt to mount the wheel on any vehicle but your own.•Your vehicle will have different driving characteristics when the spare
steel rim wheel is mounted ⇒.•The spare wheel is only intended for temporary use after having a flat tyre.
Replace the spare wheel with a normal wheel that has the proper tyre dimen-
sions as soon as possible.•If the size of the spare steel rim wheel is different to that of the other
wheels, it is unlikely that snow chains suitable for the other wheels will fit it.WARNING
•After mounting the spare steel rim wheel, the tyre pressure must be
checked and corrected as soon as possible. The inflating pressure must
adapt to the vehicle load (consult the table containing the inflation pres-
sures). Otherwise there is danger of causing an accident. Use the highest
tyre pressure as indicated in the table.•Do not drive faster than 80 km/h, as higher speeds can cause an acci-
dent.•Avoid heavy acceleration, hard braking and fast cornering, as this could
cause an accident.
