l

v
el
The electrolyte level should be checked reg-
ularly in high-mileage vehicles, in hot coun-
tries and in ol
der batteries.
Open the bonnet and then lift the cover
that protects the front part of the battery

in Working in the engine compart-
ment on page 331.
Check the colour display in the "magic eye"
on the top of the battery.
If there are air bubbl
es in the window, tap
the window gently until they disperse.
The position of the battery is shown in the
corr
esponding engine compartment diagram

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 different colours:
Black: correct charge status.
Transparent/light yellow: the battery must
be replaced. Contact a specialised work-
shop.
Charging or changing the battery
If you often drive short distances or if the ve-
hicle is not driven for long periods, the batt
ery
should be checked by a specialised work-
shop between the scheduled services.
If the battery has discharged and you have
problems starting the vehicle, the battery
might be damaged. If this happens, we rec-
ommend you have the vehicle battery
checked by a Technical Service where it will
be re-charged or replaced.
Charging the battery
The vehicle battery should be charged by a
specialised workshop only, as batteries using
special technology have been installed and
they must be charged in a controlled environ-
ment.
Replacing a vehicle battery
The battery has been developed to suit the
conditions of its location and has special
safety features. If the battery must be re-
placed, consult a technical service for infor-
mation on electromagnetic compatibility, the
size and maintenance, performance and
safety requirements of the new battery in
your vehicle before you purchase one. SEAT
recommends you have the battery replaced
by a technical service.
Start-Stop systems (

e equip-
ped with a special battery. Therefore, it must
only be replaced with a battery of the same
specifications.
Your vehicle is equipped with an intelligent
power management system to control the
distribution of electrical energy

page 344.
The power management function ensures
that the battery is charged much more effi-
ciently than on vehicles without a power
management system. To maintain this func-
tion after replacing the battery, we recom-
mend that the replacement battery used is of
the same make and type as the original fitted
battery. To make proper use of the power
management function after the battery has
been changed, have the battery coded to the
power management mode at a specialised
workshop.
WARNING
Always use only maintenance free bat
-
teries that do not run flat alone and whose
properties, specifications and size corre-
spond to the standard battery. The specifi-
cations are indicated on the battery case.
Before starting any work on the batteries,
you must read and observe the warnings
