Emergency unlocking of the ignition key
In the event of malfunc tions in the electrical
system, it may happen that you cannot re
move the ignition key.
Fi g. 28 Ig nit io n swi tc h with igni tio n key
If you are unable to remove the ignit ion key,
for example because the vehicle battery is dis
charg ed, proceed as follows :
• Press the release button
@ c::> fig. 28 and
pull the mechanical key ® out of the master
key .
• Lock the vehicle using the mechanical key
c::> page 41.
• Have the ele ctrical system inspected by a n
au thor ized Audi dealership .
Electronic immobilizer
The immobilizer helps to prevent unauthor
ized use of your vehicle.
Inside th e key th ere is a compute r chip . This
chip automatically deactiv ates the elect roni c
immobili zer when you insert the key in the ig
n ition lock. When you remove the key from
the ign ition lock, the e lectronic immob ilizer is
automatically activated once again .
@ Tips
-The vehicle cannot be started if an unau
thorized key is used . The vehicle may not
start if another radio device such as a key
fo r another vehicle o r a tra nsponder is
l oca ted on the key ring .

Power locking system
General description
The power locking system locks or unlocks all
doors and the rear lid simultaneously .
You can lock and unlock the vehicle cen trally .
You have the following choices :
- Remote master key
c::> page 40
-Door hand les with Convenience key *
c::>page40,
- Lock cylinder at the driver 's doo r
c::> page 41, or
- Powe r locking switch inside
c::>page42.
Selective unlocking
When you lock the vehicle, the power locki ng
system will lock the doo rs and the rear l id .
When unloc king, you can set in the radio or in
t h e MMI* whethe r
only the dr iver's door or
t h e enti re veh icle should be unlocked
c::> page 3 9.
Automatic lock ing
The automatic lock ing feature locks a ll the ve
hicle doors and the rear li d w hen you dr ive
f as ter than 9 mph (15 km/ h).
The car is unlocked again once the ign ition key
is removed . In add ition, the vehicle ca n be un
locked if the open ing fun ct ion in the power
locki ng sy stem switch or at one of the door
levers is actua ted .
Additionally , in the event of a crash with air
bag deployment the doo rs a re automatically
u nlocked to allow access to the vehicle.
Anti-theft alarm warning system
If the anti -theft ala rm warn ing system de
tects a b reak-in in to the vehicle, acoustic and
visual war ning s ignals are tr iggered .
The anti-theft warning system is activated au
tomat ically when you lock t he vehicle . It is de
activated when unlocki ng usi ng the

Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting
the engine .
If a vehicle with a conventional energy system
is not driven for a long period of time , the bat
tery is discharged by idling cu rrent consumers
(e.g. immobilizer). In ce rtain c ircumstances it
can result in there being insuff icient ene rgy
avai lab le to s tart the engine .
I ntelligent energy management in your vehi
cle hand les the d ist ribution of electrical ener
gy. Starting ab ility is marked ly imp roved and
the life of the battery is extended.
Basically , energy management consists of
b atter y dia gno sis, idling curr ent manag e
m ent
and dynami c en ergy m anag emen t.
Battery diagnosis
Battery d iagnosis continuously determ ines
the state of the battery . Sensors determ ine
battery vo ltage, battery curren t and battery
temperature. This dete rm ines the current
state of charge and the power of the battery .
Idling current management
Idling current management reduces energy
consumpt ion wh ile the veh icle is stand ing .
W ith the ignition switched off, it cont ro ls the
energy s upply to the va rio us electr ical compo
nents. Data from battery diagnosis is consid
ered.
D epending on the batte ry's state of charge,
i nd ividual consumers are grad ua lly turned off
to p revent excessive discharge of the battery
and thus maintain starting capability .
Dynamic energy management
W hil e the vehicle is being driven, dynamic en
e rgy management dist ributes t he energy gen-
Int ellig ent technolog y 203
erated according to the needs of the individ u
al components. It regulates consumption, so
that more electrical energy is not being used
than is being generated and ensures an opti
mal state of charge for the battery.
(D Tips
- But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are
limited.
- If start ing ability is t hreatened, the indi
cator light(•] appears¢
page 34 .
What you should know
The highest priority is given to maintaining
star ting capability.
The battery is severe ly taxed in short-distance
driving, in city traff ic and during the cold time
of year. Abundant elect rical energy is re
quired, but only a lit tle is generated . It is also
crit ical if the engine is not running and electri
cal components are turned on. In this in
stance ene rgy is be ing consumed but none is
being genera ted .
It is in precisely these situations that you will
not ice energy management actively regulat
ing the d istribution of ene rgy.
Vehicle stand s for an e xtended period
If you do not drive your vehicle over a period
of several days or weeks, e lectr ical compo
nents are gradually cut back or switched off.
This reduces energy consumption and ma in
ta ins start ing capability over a longer pe riod .
Some of the convenience func tions may not
opera te , such as the interior ligh ts or the
power seat adjustment. The convenience
funct ions w ill be available again when you
switch on the ignition and start the engine.
With the en gine turn ed off
If you listen to the radio, for exam ple, w ith
the engine turned off or use other MMI* func-
tions, the battery is being discharged .

A WARNING
Improper repairs and modifications can
change the way vehicle systems work and
cause damage to the vehicle and serious
personal injury.
