Checking and refilling 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.236.
●
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 dierent 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 correct.
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-
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 recommends 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
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 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 access to the
right technology to make the adjustment and
the correct replacement batteries.
NOTICE
The use of batteries that do not meet SEAT’s
quality specifications, or with a capacity
lower than that fitted 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 (
›››page173) 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 ››› .
