Energy management
' The starting ability is optimized
T he energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a vehicle with a conventional energy sys
tem is no t drive n for a long time, the ve hicle bat
te ry is drained by equ ipment (fo r example, t he
i mmob il iz er). I n cer ta in circ umstan ces, the re
could m ay no t be e nough energy to s tart the en
gine.
You r vehicle is equipped with an inte lligent e ner
gy management system fo r dist ributing elec trici
ty. Thi s sign ifica ntl y improves the start ing ability
and incre ases the vehicle battery life .
The ene rgy ma nagement system Is made up of
battery diagnosi s, idling current management ,
and dynamic energy management .
Battery diagnosis
T he battery diagnos is determines the vehicle bat
tery charge level. The sensors detect the ba tte ry,
the batt ery cur rent, and t he battery temperature .
The curren t cha rge level and the pe rformance of
t h e ve hicle battery are dete rm ined based on th is .
Idling current management
The idling current management decreases the
energy used while parked . With the engine
switched off , it m anages t he e ne rgy dis trib ution
to the d ifferen t electr ica l components . Data from
t h e b attery d iagnosis is ta ken into a ccou nt for
th is .
De pen ding on the vehicle batte ry c ha rge level,
e le ctri ca l eq uipme nt is switched off one i tem af
te r th e o ther to p revent t he vehi cle b attery from
dra ining and to ma intain the s tarting ab ility.
Dynamic energy management
While dr iv ing , dynam ic energy management dis
t ributes the app ropr iate amo unt of energy to t he
ele ctrica l eq uipm ent. It contro ls t he batte ry

greater than the amount being generated in or
der to maintain an optima l vehicle battery charge
l evel.
(D Tips
- Energy management cannot overcome the
laws of physics. Note that the charge level
and length of the vehicle batte ry life are
li mited.
- When the starting ability is endangered, the
(•j indicator light turns on ¢ page 14.
What you should know
Maintaining the starting ability is the highest
priority .
A lot of stress is placed on the vehicle battery
when driving short distances, during c ity driving,
and at co ld times of the year. A lot of energy is
used but little is generated. It is a lso critical
when the engine is not running but e lectr ica l
equ ipment is switched o n. In th is case, energy is
used but none is generated .
In s ituations like this, energy management will
actively regu late the distribution of ene rgy.
Long periods w ithout use
If yo u do not drive you r vehicle for several days or
weeks, e lectrica l equipment is gradually sca led
back or switched off. This reduces energy use and
ens ures the veh icle w ill be able to start after long
periods of time. Some convenience functions,
such as interior lighting or power seat adjust
ment, may not be available under certain circum
stances . These convenience functions will be
ava ilable again once you switch the ig nition on
an d s tart the engi ne.
With the engine switched off
T he vehicle battery will drain if yo u use I nfota in
ment f unctions such as listening to the rad io
while the eng ine is switched off .
The vehicle's ability to start may be impaired by
the energy use, a message will appear in the In
fotainment system d isplay .
The message ind icates that the system will
switch off automatically soon. If you wou ld like
Intellig ent Technology
to cont inue using the functions, you must start
t h e engine.
With the engine running
Alt hough e lectr ica l energy is ge nerated wh ile
dr iv ing , the ve hicle ba ttery can dra in. This ca n
happen if li ttle ene rgy is generate d but much is
u sed , and the charge level of the vehicle battery
is not optimal.
T o res to re the balance of ene rgy, componen ts
t h at require large amoun ts of ene rgy are tempo
rarily scaled back or switched off . Heat ing sys
tems in partic ula r req uire a great dea l of energy .
If you notice, for example, that the seat heating*
or rear window defogger is not work ing, then it
has been tempora rily reduced or sw itched off.
These systems are availab le aga in as soo n as the
energy sup ply has bee n restored .
In add ition, you may notice that the idle speed
has slig htly increased. That is normal and no
cause for concern . By increas ing the idling speed,
the addit ional required 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
Th is vehicle is equ ipped w ith an Event Data Re
corder (EDR) . The ma in purpose of a n EDR is to

ti ons, s uch as an airbag deployme nt o r hi ttin g a
road obsta cle, da ta t hat w ill ass ist in underst and
i ng how a vehicle 's systems performed . The EDR
is des igned to record data related to vehicle dy
namics and safety systems for a short perio d of
t ime, typ ica lly 30 seconds or less . The EDR in this
vehicle is designed to record such data as:
- How va rious systems in your vehicle were ope r
ating;
- W het her o r not the drive r and passenge r safety
be lts were b uckled/fastened;
- How far (if at all) the driver was dep ressing the
accelerator and/or bra ke pedal; and, .,,.

must be followed .
@ For the sake of the environment
Undeployed airbag modu les and pretension
ers might be classified as Perch lorate Materi
al -special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlo rate . When the veh icle o r parts of the re
stra int system including airbag modules and
safety belts w it h pretensioners are scrapped,
all applicable laws and regu lations must be
observed. Your authorized Audi dealer is fa
m iliar with these requirements and we recom
mend that you have your dealer perform this
serv ice for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced A irbag System
pe rforms in a crash. For e xamp le, using t ire -r im
comb inations no t approved by Audi, lowering t he
veh icle, chang ing the stiffness o f the suspe nsio n,
i n cluding the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic contro l unit . Some suspens ion changes
can, for example, increase the force levels meas
ured by the sensors and make the airbag system
deploy in c rashes in w hich it would not deploy if
the changes had not been made. Other ki nds of
164
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy
i ng when it should .
_& WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim comb inations can
change Advanced Airbag performance and in
crease the r isk of serious personal injury in a
crash .
- Never install suspension components that do not have the same performance charac
ter istics as the components origina lly instal
led on your vehicle.
- Never use tire-r im combinations that have
not been approved by Aud i.
