posi tion N.
A cold engine may at first be loud afte r it has
been started. This is due to the hydrau lic
valves b uilding up the oil p ress ure. This is no r­
mal and no need fo r conce rn .
If th e engine does not start imm ediately, stop
t ry ing after 10 seconds and t hen t ry to res tart
t h e engine abou t 30 seconds later.
A WARNING
-
- Never star t or le t the eng ine run in a con ­
f ined o r enclosed area . Exha ust fumes
from the en gine contain carbon monox­
ide, a co lorless and odorless gas. Carbon
monox ide ca n be fatal if inhaled.
- Never leave the engine id ling unattend­
ed. An unattended veh icle w ith a run ning
e ngine poses a danger of personal injury
or theft.
- With the engine r unning and a gear en­
gaged, you have to hold the ve hicle w it h
the foot brak e.
(D Note
-Avo id h igh engine speeds, fast accelera­
tion or heavy engine loads while the en­
gine is still cold. This could damage the
eng ine.

156 Intelligent technology
Dynamic energy management
While the veh icle is be ing driven , dynamic en­
e rgy management distributes the energy gen­
erated according to the needs of the individu­
a l components . It regu lates consumption, so
that more electrical energy is not being used
than is being generated and ensures an opti­ mal state of charge for the battery .
(D Tips
- But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are li mited .
- If starting ab ility is threatened, you are
i nformed by a warn ing
<=> page 156,
Driver notification in the instrument
cluster display .
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the cold time
of year. Abu ndant electr ical energy is re­
qu ired, but only a little is generated . It is also
cr itical if the engine is not running and elect ri­
cal components are turned on. In th is in­
stance energy is being consumed but none is
being generated .
It is in precisely these situations that you w ill
notice energy management actively regulat­
ing the distrib ution of energy .
Vehicle stands for an extended period
If you do not drive your vehicle over a period
of severa l days or weeks, elect rical compo­
nents are gradually cut back o r switched off .
This reduces energy consumption and main­
tains starting capabi lity over a longer period.
Take into considerat ion that when you un lock
your vehi cle, some convenience functions,
such as the remote key or power seat adjust­
ment, may not be available. The convenience
functions will be available again when you
turn on the ignition and start the engine. With the
engine turned off
If you listen to the radio, for examp le, w ith
the engine turned off, the battery is being dis­
charged.
If starting capability is jeopardized due to en­
ergy consumption , a message appea rs in the
driver information display.
You have to start the engine to charge the batte ry.
With the engine running
Although electrical energy is generated when
the vehicle is being driven, the battery can be­
come discharged. This happens mostly when
little energy is being gene rated and a great
deal consumed and the battery's state of
charge is not optimal.
To bring the energy balance back into equili­
brium , consume rs which requ ire espec ially
large amounts of energy are temporar ily cut
back or sw itched off. Heating systems in par­
ticu lar require a great deal of energy. If you
notice, for example, that the heated seats or
the heated rear window are not heating, they
have been temporarily cut back or switched
off . These systems will be available again as
soon as the ene rgy balance has been restored.
You wi ll also notice that engine id le speed has
been increased slightly . Th is is normal and not
a cause for concern. By increasing engine idle
speed the additional energy required is gene r­
ated and the battery is charged .
Driver notification in the instrument
cluster display
If battery power drops into the range where it
can limit the ability of the engine to start, this
is shown in the instrument cluster display
with the following driver message:
(•i Low battery charge: battery will be
charged while driving
T h is not ificat io n r eminds you that the start ing
capability of the engine may be lim ited. As
soon as you start driving again, the battery .,..
