Checking and relling levels
If a vehicle with a conventional energy system
remains stationary for a long period of time,
the electrical devices, for example in the elec-
tronic ignition lock, discharge the battery. Un-
der certain circumstances, this can lead to a
lack of electrical power to start the engine.
In your vehicle, a smart energy management
system is responsible for distributing the elec-
trical energy. This clearly improves the starting
performance and service life of the battery.
The main functions incorporated in the power
management system are battery diagnosis,
residual current management and a dynamic
power management system.
Battery diagnostics
Battery diagnostics determine the status of the
battery on an ongoing basis. The battery volt-
age, current and temperature are monitored
for this purpose. This is used to determine the
battery's charge level and eiciency.
Residual current management system
The residual current management reduces en-
ergy consumption while the vehicle is station-
ary. When the ignition is switched o, it man-
ages the power supply to the various electrical
devices. In doing so, it takes into account the
battery diagnostic data.
With the ignition on and depending on the
battery's charge level, it disconnects electrical
devices one after the other to avoid over-dis-
charging the battery and to maintain starting
capacity.
Dynamic energy management system
Energy generated while driving is distributed
by the dynamic energy management system to
the electrical devices according to their energy
requirements. It also ensures that no more en-
ergy is consumed than is generated, thus en-
suring an optimal battery charge level.
Note
●
The energy management system also can-
not override the limits imposed by the laws
of physics. Please note that the capacity and
service life of the battery are limited.

When there is a risk that the vehicle will not
start, the low battery charge level warning
lamp will be shown ›››page358.
Discharged battery
Maintaining starting capacity has top priority.
Battery strain is considerable on short jour-
neys, city driving and in the cold season of the
year.
In these situations, a lot of energy is required
but very little is generated. If the engine is
stopped and at the same time the electrical
devices are switched on, the battery can be-
come discharged to a critical point. In this case
energy is consumed without being generated
at the same time.
In these situations you will notice that the en-
ergy regulation system performs active energy
distribution adjustment.
Vehicle stationary for a long period of time
If you do not drive the vehicle for a few days
or weeks, adjustments will be made to reduce
consumption or the electrical devices will be
deactivated one by one. This reduces energy
consumption and the starting capacity is main-
tained for longer. Some comfort functions may
not be available under certain circumstances.
The comfort functions will be available again
when the ignition is switched on and the en-
gine is started.
With the engine stopped
If you listen to the radio, for example, while
the engine is stopped, the battery will be dis-
charged.
If the energy consumption means there is a
risk that the engine will not start, a text will be
displayed in vehicles with a driver information
system.
This driver message indicates that the engine
must be started to recharge the battery.
