ECU Seat Exeo 2009 Service Manual

Checking and refilling levels
232Winter 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 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 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 289.
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, 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!

Fires, sparks, naked lights and smoking are prohibited!

A highly explosive mixture of gases is released when the bat-
tery is under charge.

Wheels and tyres
242
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 may not use wheel bolts from a different car -
even if it is the same model ⇒page 214.
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 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 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.

The tools and jack are stored under the floor panel in the
luggage compartment.The tools and jack ⇒fig. 180 are stored under the floor panel
in the luggage compartment.
– Lift the floor panel using the plastic handle.
– Hook the handle onto the luggage compartment weather-
strip.
– Release the toolbox by pulling up the handle on the box. – Take out the tools or jack.
– Replace the floor panel before closing the boot lid.
The tool kit includes:•A hook for removing wheel covers* or hub caps•Box spanner for wheel bolts•A screwdriver with reversible blade•Towi ng e ye•An adapter for the anti-theft wheel bolts*
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.
