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.•The legal requirements in your country must be observed (e.g. the fitting
of a separate warning lamp).•Certain vehicle components, e.g. the rear bumper, must be removed and
reinstalled. The towing bracket securi ng bolts must be tightened using a
torque wrench, and a power socket must be connected to the vehicle's elec-
trical system. This requires specialised 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
The towing brackets should be fitted at a specialised workshop.

Checking and refilling levels
242Winter operation
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 di mensions 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 bat te r y, t his s hould be pe r form ed by a Te chnical Ser vice or qual ified
workshop. 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 cause 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 of in line with environmental regulations
and must not be disposed of with ordinary household waste. Make sure
disconnected batteries cannot tip over. Sulphuric acid could be spilt!
Important safety warnings for handling a vehicle batteryThe battery is located at the back of the engine compartment ⇒page 301.
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. Neutralise 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, open flames and smoking are prohibited. When handling
cables and electrical equipment, av oid causing sparks and electrostatic
charge. Never short the battery terminals. High-energy sparks can cause
injury.
Wear eye protection

Battery acid is very corrosive and caustic. Wear protective
gloves and eye protection!
Ž
Fires, sparks, open flames and smoking are prohibited!
Ÿ
A highly explosive mixture of gases is released when the battery
is under charge.

Keep children away from acid and batteries!

Wheels and tyres
252
For the sake of the environmentOld 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 should not use wheel bolts from a different
vehicle, even if it is the same model ⇒page 223.
After the wheels have been changed, the tightening torque of the wheel bolts
s ho uld b e che cke d as s o on as p ossible wit h a to rqu e w re 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 tightening 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 vehicle's
handling. The design of summer tyres (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.

256Spare 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. 192 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 the wheel by turning plastic knob clockwise.
– Replace the floor panel before closing the tailgate.
Your vehicle can be factory-equipped with a spare steel wheel. 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 composi-
tion, tread pattern, etc. Therefore, note the following restrictions:•The spare steel 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 tyre pressure must corre-
spond 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.
