Intelligent
technology
If starting capability is jeopa rdized due to en-
ergy consumption, a message appears in the
driver information disp lay.
You have to start the eng ine to charge the
battery.
With the engine running
Alt hough electrical energy is generated when
the vehicle is being driven, the battery can be-
come discharged. This happens most ly when
little energy is being generated and a great
deal consumed and the battery's state of
charge is not optima l.
To br ing the energy balance back into equili-
brium, consumers which require especia lly
large amounts of energy are temporarily cut
back or switched off. Heating systems in par-
ticular require a great dea l of energy. If you
notice, for example, that the heated seats* or
the heated rear window are not heating, they
have been temporar ily cut back or switched
off. These systems will be ava ilable again as
soon as the energy balance has been restored.
You will also notice that engine idle speed has
been increased slightly . This is normal and not
a cause for concern . By increas ing engine idle
speed the add itiona l energy required is gener-
ated and the ba tt ery 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, th is
is shown in the instrument cluster display
with the following driver message:
(•) Low battery charge: battery will be
charged while driving
This notification reminds you that the starting
capability of the engine may be limited. As
soon as you start driving again, the battery
will be recharged and the notification will go
out.
Driver notification appears and goes out
again
If this driver notification appears after the ig-
nition is turned 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 notif ication appears after the ig-
nition is turned on or while driving and does
not go out again, the battery 's state of charge
is not in the optimal range. Starting ab ility is
restricted . Have the battery checked as soon
as possible by an autho rized Audi dea le r o r
qualified wo rkshop.
