Disconnecting the battery
If the battery is disconnected, some of the vehicle's functions will become
inoperative (e.g. electric windows). These functions will require resetting af-
ter the battery is reconnected. For this reason, the battery should only be
disconnected from the vehicle's electrical system when absolutely necessa-
ry.
Long periods of non-use
The battery will gradually lose its charge because certain electrical equip-
ment continues to draw current even when the ignition is off. If you park the
vehicle for long periods of time in winter you should take the battery out of
the vehicle and store it in a place protected from frost. This way it will not
freeze and become damaged. At warm outside temperatures it is sufficient
to disconnect the negative terminal of the battery. Even when the battery is
not connected you should charge it from time to time.
Winter 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 rat-
ing. 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 re-
quired on the battery, this should be performed by a Technical Service or
specialised workshop. Danger of caustic burns and explosion!
● The battery must not be opened. Never try to change the battery's liq-
uid 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 dis-
connected batteries cannot tip over. Sulphuric acid could be spilt! 
Important safety warnings for handling a vehicle battery
The battery is located at the back of the engine compartment ⇒ page 304.
Wear eye protection
Battery acid is very corrosive and caustic. Wear protective
gloves and eye protection!
Fires, sparks, open flames and smoking are prohibited! 

280If and when
● Main headlight lamps: Xenon ⇒ 
lights.
● Sources of the DRL (daylight) light unit and position.
WARNING
● Take particular care when working on components in the engine com-
partment if the engine is warm - risk of burns!
● Bulbs are highly sensitive to pressure. The glass can break when you
touch the bulb, causing injury.
● The high voltage element of gas discharge bulbs* (xenon light) must
be handled correctly. Otherwise, there is a risk of death.
● When changing bulbs, please take care not to injure yourself on sharp
parts in the headlight housing.
CAUTION
● Remove the ignition key before working on the electric system. If not, a
short circuit could occur.
● Switch off the lights or parking lights before you change a bulb.
For the sake of the environment
Please ask your specialist retailer how to dispose of used bulbs in the prop-
er manner.
Note
● Depending on weather conditions (cold or wet), the front lights, the fog
lights, the tail lights and the turn signals may be temporarily misted. This
has no influence on the useful life of the lighting system. By switching on
the lights, the area through which the beam of light is projected will quickly
be demisted. However, the edges may continue to be misted.
● Please check at regular intervals that all lighting (especially the exterior
lighting) on your vehicle is functioning properly. This is not only in the inter-
est of your own safety, but also in that of all other road users. ●
Before changing a bulb, make sure you have the correct new bulb.
● Do not touch the glass part of the bulb with your bare hands, use a cloth
or paper towel instead. Otherwise, the fingerprints left on the glass will va-
porise as a result of the heat generated by the bulb, be deposited on the
reflector and impair its surface. 
Removing the air duct
The air duct has to be removed to gain access to the bulbs
for the right-side headlight.

● If the warning lamp for the side light and/or rear fog light (LED lights)
lights up, the tail light assembly should be replaced.
● The failure of the lamp is only shown when the LED function goes out
completely. Sometimes, a LED will stop working, without displaying the
warning as the function continues to operate. 

If and when
– Connect one end of the red jump lead to the positive +
termi-
nal of the vehicle with the flat battery A ⇒ Fig. 245.
– Connect the other end of the red jump lead to the positive ter-
minal +
in the vehicle providing assistance B.
– Connect one end of the black jump lead X
to a suitable ground
terminal, a solid piece of metal in the engine block, or to the en-
gine block ⇒ Fig. 245.
– Connect the other end of the black jump lead X
to a solid met-
al component bolted to the engine block or to the engine block
itself of the vehicle with the flat battery. However, connect it to
a point as far as possible from the battery A
.
4. Position the leads in such a way that they cannot come into contact with any moving parts in the engine compartment.
Starting
5. Start the engine of the vehicle with the boosting battery and let it run at idling speed.
6. Start the engine of the vehicle with the flat battery and wait one or two minutes until the engine is running.
Removing the jump leads
7. Before you remove the jump leads, switch off the headlights (if they are switched on).
8. Turn on the heater blower and heated rear window in the vehi- cle with the flat battery. This helps minimise voltage peaks
which are generated when the leads are disconnected.
9. When the engine is running, disconnect the leads in reverse or- der to the details given above. Connect the battery clamps so they have good metal-to-metal contact with
the battery terminals.
If the engine fails to start, switch off the starter after about 10 seconds and
try again after about half a minute.
WARNING
● Please note the safety warnings referring to working in the engine
compartment ⇒ page 234.
● The battery providing assistance must have the same voltage as the
flat battery (12V) and approximately the same capacity (see imprint on
battery). Failure to comply could result in an explosion.
● Never use jump leads when one of the batteries is frozen. Danger of
explosion! Even after the battery has thawed, battery acid could leak and
cause chemical burns. If a battery freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes away from batteries, dan-
ger of explosion. Failure to comply could result in an explosion.
● Observe the instructions provided by the manufacturer of the jump
leads.
● Do not connect the negative cable from the other vehicle directly to
the negative terminal of the flat battery. The gas emitted from the battery
could be ignited by sparks. Danger of explosion.
● Do not attach the negative cable from the other vehicle to parts of the
fuel system or to the brake line.
● The non-insulated parts of the battery clamps must not be allowed to
touch. The jump lead attached to the positive battery terminal must not
touch metal parts of the vehicle, this can cause a short circuit.
● Position the leads in such a way that they cannot come into contact
with any moving parts in the engine compartment.
● Do not bend over the batteries. This could result in chemical burns. 
