Always have the battery electrolyte level
checked by a qualied specialist workshop.
Charging, 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-
ed specialist workshop.
Charging the 12-volt battery
Contact a specialist workshop for charging the
12-volt battery, as the battery model tted in
the vehicle in the factory uses a technology
that requires limited voltage charging
›››
.
To do so, CUPRA recommends going to a spe-
cialised CUPRA dealer or any SEAT dealership.
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 qualied technician. CUPRA recommends
that you visit a CUPRA dealer. Component in-
formation regarding size, maintenance, power
and safety characteristics to be met can be ob-
tained from a qualied technician, who should
have the necessary documentation and tech-
nical equipment. CUPRA recommends visiting
a specialised CUPRA dealer or any SEAT deal-
ership.
The degassing hole of the 12 volt battery must
always 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 TL 825 06 and VW 7 50 73.
These standards must be dated October 2014
or later.
The 12 volt battery must always be replaced
by a qualied technician, as the vehicle's elec-
tronic system must also be adjusted as part
of the replacement. In addition, the battery
parameters relating to operational safety can
only be determined with the original battery.
Only a qualied technician has both the right
technology to make the adjustment and the
correct replacement batteries.
The use of unsuitable batteries will invalidate
the approval.
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-volt battery
•
Switch o all electrical consumers before re-
connecting the 12 volt battery.
•
First reconnect the positive cable and then
the negative one ››› .
After connecting the 12 volt battery and
switching on the ignition, several control lamps
may light up. These lamps go out after a short
distance 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 cal-
culated
›››
page 22 . In this case it will be
necessary to take into account the maximum
maintenance intervals allowed ››› page 308.
Vehicles with a “Keyless Access” system
›››
page 91: 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.
Automatic disconnection of consumers
In the event of excessive demand on the
12 volt battery, the on-board network smart
management system automatically takes cer-
tain measures to prevent the battery from dis-
charging:
