Ch eck light in the master ke y
The check light @in the master key provides
information about d ifferent cond itions .
.. The check light comes on briefly once when
a button is pressed , and during an "inquiry"
by the convenience key system .
> If the check light does not come on, the
battery is dead and has to be replaced . In
addition, when the bat tery is dead the
I!
symbol appears in the instrument cluster disp
lay as well as the message:
Ple ase
c h ange key batt ery.
Ma ster key batter y replacement
We recommend having the batte ry changed
by an authorized Audi deale r. However, if you
wish to rep lace the dead battery yourse lf, pro­
ceed as follows:
> Pull the mechanical key out of the master
key
c:> page 30 .
.. Press the release button @ on the battery
holder and at the same time pull the battery
holder out of the master key in the direction
of the arrow .
.. Install the new battery CR 2032 with the
"+" sign facing down.
> Push the battery holder carefully into the
maste r key .
> Insta ll the mechanical key.
@ For the sake of the env ironment
D ispose of dead batteries properly so as
not to pollute the environment.
(D Tips
The replacement battery must be the
same specification as the original.
Electronic immobilizer
The immobilizer helps to prevent unauthor­
ized use of your vehicle .
A computer chip ins ide your key automatically
deactivates the electronic immobilizer when
the key is inside the vehicle . When you remove
the key from the vehicle, the electron ic immo­
bilizer is automatically ac tivated once aga in .
.&, WARNING
-
A lways take the key with you when you
l eave the vehicle . T he key can disarm the
e lectronic engine immobilize r and permi t
an unauthorized person to start the engine
and enable operation of the vehicle sys ­
tems such as power window or power sun- roof leading to serious personal injury.

Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimi zes the
availability of electrical energy for starting
the engine.
I f a vehicle w ith a conventional e nergy system
is not driven for a long pe riod of time, the bat­
tery is d isch arged by idling c urrent cons umers
(e .g. immobilizer) . In ce rtain circumstances it
can result in there being i nsu fficient ene rgy
avai lab le to start the engine .
I n tell igent energy m anagement i n your veh i­
cle hand les the d istribu tion of elec trical ener ­
gy . Starting abi lity is marked ly imp roved and
the life of the battery is extended.
B asically , energy m anagement consists o f
battery diagnosis , idling current manage­
ment
and dynamic energy management.
Battery diagnosis
B att ery d iagnosis con tinuously dete rm ines
the st ate of t he battery. Senso rs determ ine
battery vo ltage, batte ry cur rent and battery
tempera ture. This dete rmines the current
state of charge and the powe r of the battery .
Idling current management
Idling current ma nagemen t red uces energy
consum ption wh ile the veh icle is stand ing.
W ith the igni tion swi tched off, i t con tro ls the
energy s upply to the va rious e lectrica l compo­
nents. Data from battery diagnosis is consid­
ered.
D epending on the battery's s ta te of charge,
individua l consumers are gra dually t urned off
to p revent excessive discha rge of the battery
and thus ma inta in start ing capability.
Dynamic energy management
W hile t he vehi cle is being driven, dynamic e n­
ergy ma nagement dis tributes the energy gen ­
erated according to the needs of the indiv idu­
al components.
It r egulates consumption, so
that more electrical energy is not being used
t h an is being generated and ensures an opti­
mal state of c ha rge fo r the battery.
(!) Tips
- But even ene rgy management cann ot
negate the limits of physics. Consider
that the powe r and life of a battery are
limited.
- If start ing ability is threatened, the indi­
cator light
(•i appears c> page 16.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severe ly taxed in short -d istance
driv ing, in city traff ic and during the cold time
o f year. Abundant electrical energy is re­
quired , but on ly a little is ge nerated . It is also
c ritical if the engi ne is not r unning and electri­
ca l components are tu rned on. In this in­
sta nce ene rgy is be ing consumed bu t none is
b eing gene ra ted .
It is in precisely these s ituations t hat yo u will
notice ene rgy management active ly regu lat­
i ng t he d istribu tion of ene rgy.
Vehicle stands for an extended period
If y ou do not drive your vehicle over a period
of several days o r weeks, e lectr ica l compo ­
nen ts a re g radually cut back or sw itched off .
T h is reduces energy consumption and ma in­
ta in s start ing ca pabili ty over a longer pe riod .
Some of the convenience func tion s may not
opera te, such as t he interior ligh ts or the
power seat adjustment. The convenience
funct ions wi ll be available again when yo u
switch on the ignition and start the eng ine . .,.

2 76 Consumer Information
Technical Modifications
Our guidelines must be complied with when
technical modifications are made .
Always consult an authorized Audi dealer be­
fore starting work on any modifications.
This will help ensure that vehicle function,
performance and safety are not impaired
¢ &. .
Attempting to work on electronic components
and the software used with them can cause
malfunctions. Because of the way electronic
components are interconnected with each
other, such malfunctions can also have an ad­
verse affect on other systems that are not di­
rectly involved. This means that you risk both
a substantial reduction in the operational
safety of your vehicle and an increased wear of
ve hicle parts ¢
A:,..
Author ized Audi dealers will perform th is
wo rk in a professiona l and competent manner
or, in special cases, refer you to a professional
company that specializes in such modifica­
tions .
A WARNING
Improper repairs and modifications can
change the way vehicle systems work and
cause damage to the vehicle and serious
personal injury.
-
If emergency repairs must be performed
elsewhere, have the vehicle examined by
an authorized Audi dealer as soon as possi­
ble.
