Check light in the master key
The check light @in the master key provides
information about different conditions .
.. 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 battery is dead
them
symbol appears in the instrument cluster disp
lay as well as the message:
Please
change key battery.
Master key battery replacement
• Pull the mechanical key out of the master
key
<=> page 32.
"' 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 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 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 activated once aga in.
_& WARNING
-
Always take the key with you when you
l eave the vehicle. The key can disarm the
e lectronic engine immobilize r 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 leadi ng to serious personal injury.
(D 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 ""

A WARNING ,~
Always adjust your driving to road and traf­
fic conditio ns. Do not let the extra safety
a ff orded by all-wheel dr ive tempt you into
taking extra risks.
-Although the all-wheel dr ive is very ef­
fec tive, a lways remember that b raking
capacity is limited by t ire traction . You
sho uld the refore no t dr ive at excess ive
speeds on icy or sl ippery road surf aces.
- On wet road su rfaces, be careful not to
dr ive too fast because the front wheels
cou ld beg in to slide on top of the water
(aq uaplaning). If this sho uld occ ur, you
will have no warning from a sudden in­
crease in engine speed as with a front­
whee l drive vehicle. A lways drive at
speeds wh ich are suited to the road con­
ditions - risk of c rash.
Energy management
Starting ability is optimized
E nergy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting the engine.
If a veh icle wit h a conven tional energy system
is not d riven for a long period of time , the bat ­
tery is discha rged by idling c urre nt cons umers
(e .g. immobilizer) . In certain circumstances it
can result in there being ins ufficient ene rgy
avai lab le to start the engine.
I ntell igent energy ma nagement in your vehi­
cle hand les the d istribution of electrical ener ­
gy . Starting abi lity is mar ked ly improved and
the life of the battery is extended .
B asically, energy management consists o f
battery diagno sis , idling current manage­
ment
and dynamic ene rgy man agement.
Battery diagnosis
B atte ry d iagnosi s con tinuously dete rmines
the state of the battery. Se nso rs dete rm ine
battery vo ltage, battery cur rent and battery
Int ellig ent technolog y 197
temperature . This de termines the current
state of charge and the power of the battery.
Idling current management
Idli ng cur ren t management reduces energy
consump tion while the vehi cle is st anding.
With the ig nition switched o ff, it controls the
energy supply to the various electrical compo­
nents . Data from batte ry diagnosis is consid ­
ered.
Depend ing on the ba ttery's state of cha rge,
individual consumers a re g radually turned off
to prevent excessive discharge of the battery
and th us maintain starting capability.
Dynamic energy management
While t he vehi cle is being dr iven, dyn ami c en­
ergy management distr ib utes the energy gen ­
erated according to the needs of the individ u­
al components. It regulates consumption, so
that more e lectrical 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
lim ited.
- If start ing ability is t hreatened, the indi­
cator light(•] appears ¢
page 17.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severe ly taxed in s hort-distance
driv ing, in city traff ic and during the cold time
of year. Ab undant electrical energy is re­
quired, but on ly a little is generated .
It is also
crit ical if the engi ne is not r unning and elec tri­
ca l components are tu rned on . In this in­
s tance ene rgy is be ing consumed b ut none is
being genera ted.
It is in precisely these situations that you will
notice ene rgy management active ly reg ulat-
i ng t he d istr ibu tion of ene rgy. ..,_ •

288 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.
