Downloaded from www.Manualslib.com manuals search engine voltage, the battery current, and the battery
temperature. The current charge level and the
performance of the battery are determined based
on this.
Idling current management
The idling cur
rent management decreases the
energy used w hile parked. With the engine
switched off, it manages the energy distribution
to the different electrical components. Date from
battery diagnosis is taken into account for this.
Depending
on the battery charge level, electrical
equipment is switched off one item after the oth
er, to prevent the battery from draining and to
retain the starting ability.
Dynamic energy manage
ment
While driving, dynamic energy management dis
tributes the appropriate amount of energy to the
electrical equipment. It controls the battery
charge level so that more energy is not used then
is being generated in order to maintain an opti
mal battery charge level.
(!) Tips
-Energy management cannot overcome the
laws of physics. Note that the charge level
and
length of the battery life are limited.

When the starting ability is jeopardized, the
r-1 indicator light turns on ~page 13.
What you should know
Maintaining the starting ability is the highest
priority.
A lot of stress is placed on the battery when driv
ing
short distances, in traffic, and at cold times
of the year. A lot of energy is used but little is
generated. It is also critical when the engine is
not running but electrical equipment is switched
on . In this case, energy is used but none is gener
ated.
In situations like this, energy management will
actively regu l
ated the distribution of energy.
Intelligent T echnology
Long periods without use
If you do not drive your vehicle for several days or
weeks, electrical consumers are gradually scaled
back
or switched off. This reduces energy use and
ensures the vehicle will be able to start after long
periods
of time. Some convenience functions
such
as opening with the remote control key may
not be available. These convenience functions
will be available again once you switch
the igni
tion on and start the engine.
With the engine switched off
The battery will drain if you use Infotainment
functions such as listening to the radio while the
engine is switched off.
The vehicle's
ability to start may be impa ired by
the energy use, a message will appear in the In
fotainment system display. The message indi
cates that the system will switch off automatical
ly soon. If you would like to continue using the
functions, you must start the engine.
With the engine running
Although electrical
energy is generated while
driv ing,
the battery can drain. This can happen
when little energy is generated, and much is used
and the charge level of the battery is not optimal.
To
restore the balance of energy, components
that require large amounts of energy are tempo
rarily scaled back or switched off. Heating sys
tems in particular require a great deal of energy.
If you notice, for example, that the seat heating*
or rear window defroster is not working, then it
has been temporarily re d uced or sw itched off.
T
hese systems are availab le again as soon as the
energy balance has been restored.
In addition, you may notice that the idle speed
has slightly increased. That is normal and no
cause for concern. Due to the increased idling
speed, the additional required energy will be
generated and the battery will be charged.
