Energy management
The starting ability is optimized
The energy manag ement syst em manages th e
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a vehicle w ith a conventional energy sys
tem is not dr iven for a long time, the batte ry is
d rained by equ ipment (for example the immobi l
i ze r) . In certain circumsta nces, there could may
n ot be eno ugh energy to st art the engine.
Your veh icle is equipped with an intellige nt ener
gy management system for d istr ibut ing electric i
ty . This s ignificantly im proves the s tarting ab ility
an d incr eases t he battery life.
The energy management system Is made up of
batter y diagnosis , idling current management
and dynami c energy management.
Battery diagnosis
The battery diagnosis determ ines the battery
charge level. The senso rs determ ine the battery
voltage, the battery current, and t he battery
t e m perature . Th e cu rrent charge level a nd the
p e rformance of the b attery are dete rm ined based
on this.
Idling current management
The idling c urrent management dec reases the
e n ergy used wh ile pa rked . With the eng ine
sw itched off, it manages the energy dist ribution
t o the different elect rical componen ts. Date from
b attery d iagnosis is ta ken into a ccount for this.
Depending on the battery cha rge level, e lectr ica l
eq uipment is switched off o ne item after the o th
e r, to p revent the batte ry from draini ng an d to
r eta in the s tarting ab ili ty.
Dynamic energy management
W hile driving, dy namic energy management dis
tr ibutes the appropriate amount of energy to the
e lectr ica l equipment.
It con trols the battery
ch arge level so th at more energy is not used then
i s being gener ate d in orde r to m aint ain a n op ti
mal battery charge level.
Intellig ent Technology
{!) Tips
- Energy management cannot overcome the
laws o f physics . Note that the charge level
and length of the battery life are limited.
- W hen the sta rting ability is endangered, the
(•) indicator light t urns on
¢ page 17.
What you should know
Maintaining the starting ability is the highest
priority .
A lo t of stress is p laced on t he b attery when dr iv
ing short d istances, in t raffic, and at cold times
of the year . A lot of energy is used but litt le is
generated .
It is also critical when the eng ine is
not r unning but e lectr ica l equipment is sw itched
o n . In th is case, energy is used but none is gener
ated .
In situat ions like th is, energy management w ill
active ly regulated the distr ibut ion of energy.
Long periods without use
If you do no t drive your vehicle for severa l days o r
weeks, electrical eq uipment is gradua lly scaled
back or sw itched off . This reduces e nergy use and
ensures the vehicle will be ab le to start after long
per iods of time . Some conven ience f unctions
such as opening w it h the remote control key may
not be availab le . Th ese convenience functions
will be ava ilable again once you switch the ign i
t io n on and sta rt the eng ine.
With the engine switched off
The battery w ill dra in if you use funct io ns such as
li ste ning to the radio wh ile the engine is switch
ed off .
The vehicle's ab ility to start may be impa ired by
the energy use, a message will appear in the In
fota inme nt system display .
The message indicates that the system w ill
switch off automatically soon . If you would like
to continue using the functions, you must start
the engine .
IJJ,,
121
Intelligent Technology
With the engine running
A lthough electrical energy is generated whi le
driving, the battery can drain . This can happen
when little energy is generated, and much is used
and the charge leve l of the battery is not optima l.
To restore the balance o f energy, components
that requ ire large amounts o f energy are tempo
rari ly scaled back o r switched off . Heating sys
tems in particu lar require a great deal of energy.
If you notice, for example, that the seat heating*
or rear window defroster is not working, then it has bee n temporarily reduced or switched off.
These systems are available again as soon as the
energy supp ly has been restored.
In addition, you may notice that the idle speed
has slightly increased. T hat is norma l and no
cause for concern. Due to the increased idling
speed, the add itiona l requ ired e ne rgy w ill be
generated and the battery w ill be cha rged.
Notice about data recorded by the Event
Data Recorder and vehicle control modules
E vent Data Recorder
This vehicle is equipped wi th an Event Da ta Re
corde r (EDR) . The main purpose of an EDR is to
record, in certain crash o r near crash-like situa
tions, such as an a irbag deployment or h itting a
road obstacle, data that will assist in understand
ing how a veh icle's systems performed . The EDR
is designed to record data related to veh icle dy
namics and safe ty systems for a sho rt pe riod of
time, typically 30 seconds or less. The EDR in this
veh icle is designed to reco rd s uch data as:
- How various systems in your vehicle were oper
at ing;
- Whether or not the driver and passenger safety belts we re buckled/fastened;
- How far ( if at all) the driver was depress ing the
acce lerator and/or brake peda l; and,
- How fast the ve hicle was trave ling.
These data can help provide a better understand ing of the circ umstances in which crashes and in
juries occur. NOTE: EDR data are recorded by your veh icle only if a non-trivia l crash situat ion occurs;
no data are recorded by the EDR under norma l
122
driving cond itions and no personal data (e .g .,
name, gender, age, and crash location) are re
corded. However, other parties, such as law en
fo rcement, co uld comb ine the EDR data with the
type of persona lly identifying data rout inely ac
quired du ring a crash investigation .
To read data recorded by an EDR, spec ial eq uip
ment is required, and access to the vehicle or the
EDR is needed. In addition to the ve hicle manu
facturer, other part ies, such as law enforcement,
t h at have the spec ial eq uipment, can read the in
fo rmat io n if they have access to the vehicle or the
EDR .
Some state laws restrict the retrieval or down
l oad ing of data stored by ED Rs ins talled in a ve hi
cle for the exp ress p urpose of ret riev ing data af
te r an accident or c rash event withou t the own
e r's consent.
Audi will not access the EDR and/or simi la r data
or g ive i t to others -
- unless the ve hicle owner (or lessee if the vehi
cle has been leased) agrees; o r
- upon the offic ial request by the police; or
- upon the order of a court o f law or a govern -
ment agency; or
- for the defense of a lawsuit thro ugh the judicia l
discovery process.
- Audi may a lso use the data for research about
veh icle operation and safety perfo rmance or
prov ide the data to a third party for research
purposes without identify ing the specific vehi
cle or information about the ident ity of its own
er or lessee and only afte r the recorded vehicle
data has been accessed.
Vehicle control modules
You r vehicle is also eq uipped with a number of
electronic control modules for various vehicle
systems, such as e ngine management, em iss ion
contro l, airbags, and safety be lts.
These elect ronic contro l modules record data
dur ing norma l vehicle operation that may be
needed by trained techn ic ians for d iagnost ic and
