Practical tips
Charging or changing the battery
If you often drive short distances or if the ve-
hicle is not driv
en for long periods, the 12-volt
battery should be checked by a specialised
workshop more frequently than the service
intervals.
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 12-volt vehicle battery has been de-
signed to suit its location and has special
safety features. If you need to change the
battery, please go to a service centre before
buying a new one to get information about
the electromagnetic compatibility, size and
maintenance requirements, performance and
safety of your vehicle’s new battery. SEAT
recommends you have the battery replaced
by a technical service.
Start-Stop systems (

page 219) are 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 326.
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
●
Alw
ays 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
›››
in General information on page 324.
For the sake of the environment
Batteries contain toxic substances such
as sulphuric acid and l
ead. They must be
disposed of appropriately and must not be
disposed of with ordinary househol
d waste.
Energy management
Optimisation of the star
ting ca-
pacity
The power management controls the distri-
bution of electrical ener
gy and thus helps to
ensure that there is always enough power
available to start the engine.
If a vehicle with a conventional electrical sys-
tem is left parked for a long time, the battery
will gradually lose its charge because certain
electrical devices, such as the electronic
gearbox lock continues to draw current even
when the ignition is off. In some cases there
may not be enough power available to start
the engine.
Your vehicle is equipped with an intelligent
power management system to control the
distribution of electrical energy. This signifi-
cantly improves reliability when starting the
engine, and also prolongs the useful life of the
battery.
The main functions incorporated in the power
management system are battery diagnosis,
residual current management and dynam-
ic power management.
