Energy management
The starting ability is optimized
The energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a vehicle w ith a conventional energy sys
tem is not dr iven for a long time, the battery is
d rained by equ ipme nt (for example the immobi l
iz er) . In certain circumstances, there could may
not be eno ugh energy to start the engi ne.
Your veh icle is equipped with an inte lligent ene r
gy managemen t system for d istr ibut ing electrici
ty . This significant ly imp roves the starting ab ility
and inc reases t he battery life.
The energy management system Is made up of
batt ery diagno sis, idling curr ent management
and dynami c en ergy managemen t.
B attery diagnosis
The battery diagnosis determines the battery
charge level. The senso rs determ ine the battery
voltage, t he battery cur rent, and the battery
temperature. The cu rrent charge level a nd the
pe rformance of the bat tery are dete rm ined based
on this .
Idling current management
The idling cu rrent management dec reases the
energy used wh ile parked . With the eng ine
sw itched off, it manages the energy dist ribution
t o the different elect rical componen ts. Date from
battery d iagnosis is taken into account for this.
D epending on the battery cha rge level, e lectr ica l
equ ipment is swi tched off one item after the oth
e r, to p revent the ba tte ry from d raining and to
r etain the s tarting ab ility.
Dynamic energy management
Wh ile driving, dynamic energy management dis
tr ib utes the approp riate amount of energy to the
e lectr ica l 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.
(D Tips
- Energy management cannot overcome the
laws of physics . Note that the charge level
and length o f the battery life are limited.
- When the sta rting ability is endangered, the

What you should know
Maintaining the starting ability is the highest
priority.
A lo t of st ress is p laced on t he b attery when dr iv
ing shor t distances, in traff ic, and at cold t imes
of the year . A lot of energy is used but litt le is
generated. It is also critical when the engine is
not running but e lectr ica l equipment is sw itched
on. In th is case, energy is used but none is gener
ated.
In situations like this, energy management wi ll
active ly regulated the distr ibut ion of energy.
Long periods without us e
If you do not drive your vehicle for sever al days o r
weeks, electrical equ ipment is gradua lly scale d
back or sw itched off . This reduces energy use and
ensures the vehicle will be ab le to start after long
per iods of time . Some conven ience functions,
such as interior lig hting or power seat ad just
ment, may not be ava ilable under certain circum
stances. These conven ience functions wi ll be
available again once you sw itch t he ignition on
and sta rt the eng ine.
With the engine switched off
The battery w ill dra in if you use Infotainment
funct ions such as listening to the radio while the
engi ne is switched off .
The vehicle's ab ility to start may be impa ired by
the energy use, a message will appear in the In
fota inment system display .
The message indicates that the system wi ll
switch off automatically soon. If you would like
