Intelligent Technology
Depending on the vehicle battery charge level,
electrical equipment is switched off one item af
ter the other to prevent the vehicle battery from
draining and to maintain the starting ability.
Dynamic energy manag ement
W hile driving, dynamic energy management d is
trib utes the appropriate amount of energy to the
e lectrical equipment. It controls the battery
charge level so that the amount of energy is not
greater than the amount be ing generated in or
der to mainta in a n optima l vehicle battery charge
level.
(D Tips
- Ene rgy management cannot ove rcome the
l aws of physics . Note that the charge level
and length of the vehicle battery life a re
l imi ted.
- When the starting ability is endangered, the
(•) indicator light turns on

What you should know
Maintaining the starting ability is the highest
priority.
A lot of stress is placed on the vehicle battery
when dr iv ing short d ista nces, dur ing c ity dr iving,
and at cold times of the year . A lot of energy is
used but little is ge nerated.
It is a lso critical
when the engine is not runn ing but e lectr ica l
eq uipment is switc hed o n. In this case, energy is
used bu t none is ge ne ra te d.
In s ituations like this, energy manageme nt will
actively regu late the d istribution of ene rgy .
Long periods without use
I f yo u do not drive your vehicle for seve ral days or
weeks, electrical equipment is gradually scaled
back or switched off . This red uces energy use and
ensu res the veh icle w ill be able to star t afte r long
pe riods of time . Some convenience functions ,
such as inte rior lighting or powe r seat adjust
men t, may not be available unde r certa in ci rcum
s tances. These co nvenience functions will be
ava ilab le again once you switch the ign ition on
and start the engine .

With the engine switched off
The vehicle b attery wi ll dr ain if you use Info tain
ment func tions such as lis teni ng to the radio
while the engine is switched off.
The veh icle's abili ty to s ta rt may be impa ired by
the e nergy use, a message will appe ar i n t he I n
fota inment system display.
The message indicates that the system wi ll

If you would lik e
to co ntin ue usi ng the func tio ns , you mus t start

With the engine running
Althoug h electrica l energy is gene rated w hile
driv ing, the veh icle ba tte ry can dra in. This can
happe n if li tt le ene rgy i s generate d but much is

i s not optimal.
To resto re t he ba lan ce of energy, co mponents
t h at req uire large amo unts of energy a re tempo
ra rily sc aled b ack or sw itche d off. Heat ing sys
tems in partic ular re quire a great deal of energy .
If you notice, for example, that the seat heating*
or r ear window defogger is not work ing, then it
has been tempora rily reduced or switched off.
These systems are avai lab le aga in as soon as t he
energy supply has bee n restored .
In ad dition, yo u may notice that the idle speed
has slightly increased. That is normal and no
cause for concern. By increasing the idling speed,
the addit ional required energy will be ge nerated
and the veh icle battery w ill be charged .
