when you turn on the ignition and start the
engine.
With the engine turned off
If you listen to the radio, for example, with
the engine turned off or use other MMI func-
tions, the battery is being discharged.
If starting capability is jeopardized due to en-
ergy consumpt ion, the following warning ap-
pears in the MMI disp lay:
Please start engine, otherwise system will
switch off in 3 minutes.
The warning ind icates that the system will be
turned off automatically after 3 minutes . If
you wish to cont inue using the functions, you
have to start the engine.
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 generated and a great
deal consumed and the battery's state of
charge is not optimal.
To br ing the energy balance back into equili -
brium, consumers which require especially
large amounts of energy are temporarily cut
back or swit ched off. Heating systems in par-
t icular requ ire 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 temporari ly cut back or switched
off. These systems will be available again as
soon as the energy balance has been restored.
You will also notice that engine idle speed has
been increased slight ly. This is norma l and not
a cause for concern . By increasing engine idle
speed the additiona l energy required is gener-
ated and the battery is charged.
Driver notification in the instrument
cluster display
If battery powe r drops int o 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.ow battery charge: battery will be
charged while driving
This not ificat ion reminds you that the start ing
capability of the engine may be limited. As
soon as you start dr iving again, th e battery
will be recharged and t he not if icat ion will go
out.
Driver notification appears and goes out
again
If t his driver notification appears after the ig-
nition is t urned on or whi le driving and it goes
out again after a while, the battery has been
adequately recharged.
Driver notification appears and does not
go out again
If this driver notification appears after the ig-
nition is turned on or whi le driving and does
not go out again, the battery's state of charge
is not in the optimal range. Starting abili ty is
restricted. Have the battery checked as soon
as possible by an authorized Audi dealer or
qualified workshop.
