Checking and relling levels
Yellow or colourless:
Black:
Check the level
The electrolyte level should be checked regu-
larly in high-mileage vehicles, in hot countries
and in older batteries.
●
Check the colour display in the sight glass on
the top of the battery ›››Fig.232.
●
If there are air bubbles in the window, tap
the window gently until they disperse.
The “magic eye” indicator, located on the top
of the battery changes colour, depending on
the charge state and electrolyte level of the
battery.
There are two dierent colours:
The battery's electrolyte
level is too low. Go to a specialised work-
shop to have the battery checked and re-
placed if necessary.
The battery’s electrolyte level is cor-
rect.
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 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 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.
NOTICE
The use of batteries that do not meet CU-
PRA’s quality specications, or with a ca-
pacity lower than that tted as standard,
could, depending on the local legislation in
each country, lead to the loss of approval or
the corresponding administrative permits for
the vehicle. In addition, it may pose a serious
safety risk.
Vehicles with Start-Stop functions (
›››page174) are tted with a special battery.
Therefore, it must only be replaced with a bat-
tery of the same specications.
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 ››› .
