Char
ging, replacing, disconnecting
and connecting the 12-volt battery
If you suspect that the 12-volt battery is dam-
aged or defective, have it checked by a quali-
fied specialist workshop.
Charging the 12-volt battery
Contact a specialist workshop for charging the
12-volt battery, as the battery model fitted in
the vehicle in the factory uses a technology
that requires limited voltage charging ›››
.
SEAT r
ecommends visiting a SEAT dealership
for this.
Replacing the 12-volt battery
The 12-volt vehicle battery has been designed
to suit its location and has special safety fea-
tures. If a 12 volt battery needs to be replaced,
the replacement battery must be installed by
a qualified technician. SEAT recommends visit-
ing a SEAT dealership. Component information
regarding size, maintenance, power and safety
characteristics to be met can be obtained from
a qualified technician, who should have the
necessary documentation and technical equip-
ment. SEAT recommends visiting a SEAT deal-
ership.
The degassing hole of the 12 volt battery must
al
ways be on side of the negative pole. The
degassing hole on the side of the positive pole
must always be sealed.
Only use maintenance-free 12 volt batteries
that comply with the TL 825 06 and VW 7 50 73
standards. These standards must be dated Oc-
tober 2014 or later.
The 12 volt battery must always be replaced
by a qualified technician, as the vehicle's elec-
tronic system must also be adjusted as part
of the replacement. In addition, the battery pa-
rameters relating to operational safety can only
be determined with the original battery. Only a
qualified technician has both the right technol-
ogy to make the adjustment and the correct
replacement batteries.
The use of unsuitable batteries will invalidate
the approval.
Vehicles with Start-Stop functions (
›››page158) are fitted with a special battery.
Therefore, it must only be replaced with a bat-
tery of the same specifications.
Disconnecting the 12-volt battery
If the 12 volt battery is to be disconnected from
the vehicle's electrical system, please note the
following:
●
Switch o all electrical consumers.
●
Before disconnecting the battery, unlock the
vehicle, otherwise the alarm will be triggered.
●
First disconnect the negative cable and then
the positive cable ›››
.
Connecting the 12-v
olt battery
●
Switch o all electrical consumers before re-
connecting the 12 volt battery.
●
First reconnect the positive cable and then
the negative one ›››
.
Aft
er connecting the 12 volt battery and switch-
ing on the ignition, several control lamps may
light up. These lamps go out after a short dis-
tance at a speed of approx. 15 to 20 km/h (10
to 12 mph). If the warning lights do not go out,
visit a specialist workshop and have the vehicle
checked.
If the 12-volt battery has been disconnected for
a long period of time, it is likely that the next
service is not correctly indicated or calculated
›››page18 . In this case it will be necessary
to take into account the maximum maintenance
intervals allowed ›››page362.
Vehicles with a “Keyless Access” system
›››page90: If the ignition cannot be switched
on after connecting the 12 volt battery, lock and
unlock the vehicle from the outside. Then try to
switch on the ignition again. If the ignition does
not work, seek professional assistance.
