Check li ght in the ma ste r key
The check light @ in the master key prov ides
information about different cond itions .
• The check light comes on briefly once when
a button is pressed, and during an "inquiry"
by the conven ience key system .
• If the check light does not come on, the
battery is dead and has to be replaced. In
addition, when the battery is dead the

Ma ster ke y battery replacement
We recommend having the battery changed
by an authorized Audi dea ler. 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 31.
• 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.
• Insta ll the new battery CR 2032 with the
"+" sign facing down.
• Push the battery holder carefully into the
master key .
• Install the mechanical key.
@ For the sake of the environment
Dispose of dead batteries properly so as
not to pollute the environment.
(D Tips
The replacement battery must be the
same specification as the origi nal.
Electronic immobilizer
The immobilizer helps to prevent unauthor­
ized use of your vehicle.
A computer chip inside 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 activated once aga in .
.&, WARNING
-
A lways take the key with you when you
leave the vehicle. The key ca n disa rm the
e lectronic engine immobilizer and permit
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. .,

194 Intelligent technolog y
-On wet road surfaces, be carefu l not to
dr ive t oo fast because the front wheels
could beg in t o slide on top of the water
(aq uaplaning). If this sho uld occur, you
will have no wa rning from a su dden in­
c rease in engine spee d as with a front­
wheel drive vehicle. A lways d rive at
speeds wh ich are suited to the road con­
di tions - ris k of crash.
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 d ischarged by idling current consumers
(e.g . immobilizer) . In certain circumstances it
can result in there being insufficient energy
avai lab le to start the engi ne .
Intell igent energy management in your veh i­
cle hand les the d istribution of electrical ener­
gy. Starting ab il ity is markedly improved and
the life of the battery is extended .
Basically, energy management consists of
battery diagno sis, idling curr ent manage­
ment
and dynami c energ y man agement .
Battery diagno sis
Battery diagnosis continuously determines
the state of the battery. Sensors determ ine
battery vo ltage, battery current and battery
temperature . This determ ines the current
state of charge and the powe r of the battery.
Idling current man agement
Idling current management reduces energy
consumption while the vehicle is stand ing.
W ith the ignition switched off, it contro ls the
energy supply to the various electr ical compo­
nents . Data from battery diagnosis is consid­
e red. Depend
ing on the battery's state of cha rge ,
individua l consumers are g radually turned off
to prevent excessive discharge of the battery and th us maintain starting capability.
Dynamic energy manag ement
While the vehi cle is being d riven, dynamic en ­
ergy management distributes the energy gen ­
erated accord ing to t he 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 fo r the battery .
(D Tips
-But even energy management cannot
negate the limits of physics. Consider
tha t the powe r and life of a battery are
limited.
- If start ing ability is threatened , the indi­
cator light

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
of year . Abundant electrical energy is re­
quired, but on ly a little is generated . It is also
c rit ical if the engine is not r unning and e lectri­
ca l components are tu rned on . In this in­
sta nce ene rgy is be ing consumed b ut none is
being gene ra ted.
It is in prec isely these s ituations that you will
notice ene rgy management a ctive ly regu lat­
i ng t he d istribu tion of ene rgy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period
of several days or weeks, electr ica l compo­
nents a re g radually cut back or sw itched off.
T h is reduces energy consumption and ma in­
ta ins start ing capability over a longer pe riod .

Technical Modifications
Our guidelines must be complied with when technical modifications are made .
Always consult an authorized Aud i dealer be ­
fore starting work on any modifications.
This will he lp 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. Beca use 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 . Th is means that you r isk both
a substantial reduction in the operational
safety of you r vehicle and an inc reased wea r of
vehi cle parts¢ _&..
Author ized Audi dealers w ill perform th is
wo rk in a professiona l and competent ma nner
or, in spec ial cases, refer you to a p rofessional
company that specializes in such mod ifica­
tions .
_& WARNING t= -
Improper repairs and modifications can
change the way vehicle systems wo rk and
cause damage to the veh icle and ser ious
personal injury.
(D Note
If emergency repairs must be performed
elsewhere, have the veh icle examined by
an authorized A udi dealer as soon as possi­
ble.
