Practical tips
●
Never turn the 12-volt battery over. Elec-
trolyte could leak out of the vents and
cause burns.
●
Never open a 12-volt battery.
●
If the electrolyte splashes onto the skin
or eyes, rinse the affected area with cold
water for a few minutes. Then seek medical
care immediately.

Charging, replacing, disconnect-
ing and connecting the 12-volt bat-
tery
If the 12-volt battery is suspected of being
damaged or defective, have it checked by a
qualified establishment.
Charging the 12-volt battery
The 12-volt battery must be charged at a
qualified establishment, as the factory fitted
12-volt battery technology requires a voltage
limited charge
. SEAT recommends visit-
ing a SEAT dealership for this.
Replacing the 12-volt battery
The 12-volt battery is developed to suit its lo-
cation and has special safety features. When
a 12-volt battery needs to be replaced, be-
fore buying a new one you must ask a SEAT
dealership about electromagnetic compati-
bility, size and maintenance, power and safe-
ty requirements that the new battery must
meet. The 12-volt battery's vent must always
be on the side of the negative terminal and
the vent on the positive terminal must always
be closed.
A maintenance-free battery that meets the
TL 825 06 and VW 7 50 73 standards must al-
ways be used. These standards must be dat-
ed October 2014 or later.
The 12-volt battery must always be replaced
by a qualified establishment, as it is necessa-
ry to adjust the vehicle's electronic system as
part of its replacement. Only a qualified es-
tablishment has the appropriate technology
to make this adjustment correctly. SEAT rec-
ommends that the 12-volt battery be re-
placed by a SEAT dealer.
Disconnecting the 12-volt battery
If the 12-volt battery needs to be disconnec-
ted from the vehicle's electrical system, these
steps should be followed:
●
Switch off the ignition and all electrical
consumers.
●
Before disconnecting the battery, unlock
the vehicle or theft alarm system will activate.
●
First disconnect the negative cable and
then the positive cable
.
Connecting the 12-volt battery
●
Before reconnecting the 12-volt battery,
disconnect all electrical consumers and the
ignition.
●
First reconnect the positive cable and then
the negative one
.
After connecting the 12-volt battery and turn-
ing on the ignition, different indicator lights
may come on. They will turn off when a short
distance is driven at approximately 15-20
km/h. If the warning indicators remain lit,
please visit a qualified establishment to have
the vehicle checked.
If the 12-volt battery has been disconnected
for a long time, it's possible that the next serv-
ice appointment might not be displayed or
calculated correctly.
. Respect
the maximum service intervals permitted
›››
.
Automatic disconnection of consumers
Thanks to the smart management of the on-
board network, when the 12-volt battery is
overcharged different measures are taken to
prevent the 12-volt battery from discharging:
●
If necessary, the power in the largest con-
sumers is limited, or they are disconnected
completely in an emergency.
However, on-board network management
cannot always prevent the 12-volt battery
