0 co .... N ,..... N .... 0 0 :c ' Your vehicle is equipped with an intelligent ene r­
gy management system for distributing electrici­
ty. This s ignif icantly improves the starting abi lity
and increases the vehicle battery life.
The energy management system Is made up of
batt ery diagno sis , idling current management ,
and dynam ic energ y man agement.
Battery diagnosis
The batte ry diagnosis de termines the vehicle bat ­
tery charge level. The sensors determ ine the bat ­
tery voltage, the battery current, and the battery
temperature. The current charge level and the performance of the vehicle battery are deter­
mined based on th is.
Idling curr ent manag ement
The idling current management decreases the
energy used whi le parked . With the engine
switched off, it manages the energy distribution
to the different electrical components. Data from
the battery diagnosis is taken into account for
this .
Depending on the vehicle battery charge level,
e lectrical equipment is sw itched off one item af ­
ter the other to prevent the vehicle battery from
draining and to maintain the starting ability .
Dynamic en erg y manag ement
While driving, dynamic energy management dis­
tr ibutes 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 being generated in or­
der to ma inta in an optimal veh icle battery charge
l evel.
(D Tips
- Energy management cannot overcome the
laws of physics . Note that the charge level
and length of the vehicle battery life a re
limited .
- When the start ing ability is endangered, the

Intellig ent Technology
What you should know
Maintaining the starting ability is the highest
priority .
A lot of stress is placed on the veh icle battery
when driving short distances, during city driving, and at cold times of the year . A lot of energy is
used but little is generated. It is also critical
whe n the eng ine is not r unni ng but elect rical
equipmen t is switched on . In this case, energy is
u sed but none is generated.
In situat ions like th is, energy management w ill
active ly regulate the distrib ution of energy.
Long period s without use
If you do not drive your vehicle for severa l days or
weeks, electrical equ ipment is gradually scaled
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 f unctions,
s u ch as interio r lig hting or power seat adjust­
ment, may no t be av ailable under certain circum­
stances . These conven ience f unctions wi ll be
available again once you sw itch the ignition on
and start the engine.
With the engine switched off
T he veh icle ba tte ry w ill dr ain if you use Info tain­
ment functions such as listening to the radio
whi le the engine is switched off.
If the sta rting abili ty is impaired by the energy
u se, the following message will appear in the In ­
fotainment system display:
Please start the engine , otherwi se the system
will turn off shortl y.
This message indicates that the system will
switch off automatically after 3 m inutes . If you
would like to continue us ing the funct ions, you
must start the engine.
With the engine running
Although e lectr ica l energy is generated while
driv ing, the ve hicle battery can drai n. This can
happen if litt le energy is generated b ut much is
used , and the charge level of the vehicle battery
is not optimal. .,.
131

Intelligent Technology
To restore the balance of energy, components
that require large amounts of energy are tempo­
rarily scaled back or switched off. Heating sys­
tems in particular require a great deal of energy .
If you notice, for example, that the seat heating"
or rear window defogger is not working, then it has been temporarily reduced or switched off .
These systems are available again as soon as the
energy supply has been restored.
In addition, you may notice that the idle speed
has slightly increased. That is normal and no
cause for concern . By increasing the idling speed,
the additional requ ired energy will be generated
and the vehicle battery will be charged.
Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
Event Data Recorder
This vehicle is equipped with an Event Data Re­
corder (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like situa­
tions , such as an airbag deployment o r hitting a
road obstacle, data that will assist in understand­
ing how a vehicle 's systems performed. The EDR
is designed to record data related to vehicle dy­
namics and safety systems for a short period of
time, typically 30 seconds or less. The EDR in this
vehicle is designed to record such data as :
- How various systems in your vehicle were oper­
ating;
- Whether or not the driver and passenger safety
belts were buckled/fastened;
- How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
- How fast the vehicle was traveling.
These data can help prov ide a better understand­
ing of the circumstances in which crashes and in­
juries occur. NOTE: EDR data are recorded by your
vehicle only if a non-trivial crash situation occurs ;
no data are recorded by the EDR under normal
driving conditions and no personal data (e .g.,
name, gender, age, and crash location) are re­
corded. However, other parties, such as law en-
132
forcement, could combine the EDR data with the
type of personally identifying data routinely ac­
quired during a crash investigation.
To read data recorded by an EDR, special equ ip­
ment is required, and access to the vehicle or the
EDR is needed . In addition to the vehicle manu­
facturer, other part ies, such as law enforcement,
that have the special equipment, can read the in­
formation if they have access to the vehicle or the
EDR .
Some state laws restrict the retrieval or down­
loading of data stored by ED Rs installed in a vehi­
cle for the express purpose of retrieving data af­
ter an accident or crash event without the own ­
er 's consent .
Audi will not access the EDR and/or simi lar data
or give it to others -
- unless the vehicle owner (or lessee if the vehi ­
cle has been leased) agrees; or
- upon the official request by the police; or
- upon the order of a court of law or a govern-
ment agency; or
- for the defense of a lawsuit through the judicial
discovery process.
- Audi may also use the data for research about
veh icle operation and safety performance or
provide the data to a third party for research
purposes without identifying the specific vehi­
cle or information about the identity of its own ­
er or lessee and only after the recorded vehicle
data has been accessed.
Vehicle control modules
Your vehicle is also equipped with a number of
electronic control modules for various vehicle
systems, such as engine management, emission control, airbags, and safety belts.
These electronic control modules record data during normal vehicle operation that may be
needed by trained technicians for diagnostic and
repair purposes. The recording capability of these
modules is limited to data (no sound is record­
ed) . Only a small amount of data is actually re­
corded over a very limited period of time, or stor­
ed when a system fault is detected by a contro l
module . Some of the data stored may relate to .,._
