Energy Management - Seat Leon Owner's Manual

Charging or changing the battery
If you often drive short distances or if the ve-
hicle is not driven for long periods, the battery
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.
Checking and refilling levels
›››
Start-Stop systems ( page 203) 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
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

Optimisation of the starting ca-
pacity
The power management controls the distri-
bution of electrical energy 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.
