function after replacing the battery, we rec-
ommend that the replacement battery used
is of the same make and type as the original
fitted battery. To make proper use of the pow-
er management function after the battery
has been changed, have the battery coded
to the power management mode at a speci-
alised 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

as sulphuric acid and lead. They must be
disposed of appropriately and must not be
disposed of with ordinary household waste.

Practical tips

Energy management

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.
Battery diagnosis
The battery diagnosis function constantly
registers the condition of the battery. Sensors
detect the battery voltage, battery current
and battery temperature. This enables the
system to calculate the current power level
and charge condition of the battery.

Residual current management

The residual current management reduces
power consumption while the vehicle is
parked. It controls the supply of power to the
various electrical devices while the ignition is
switched off. The system takes the battery di-
agnosis data into consideration.
Depending on the power level of the battery,
switch off the individual electrical devices
one after the other to prevent the battery
from losing too much charge and to ensure
that the engine can be started reliably.

Dynamic power management

While the vehicle is moving, this function dis-
tributes the available power to the various
electrical devices and systems according to
their requirements. The power management
ensures that on-board systems do not con-
sume more electrical power than the alterna-
tor can supply, and thus maintains the maxi-
mum possible battery power level.
