Check light in the master key
The check light @ in the master key provides
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 bat­
tery is dead and has to be replaced. In addi­
t ion, when the battery is dead the
I!! sym­
bol appears in the instrument cluster dis-

Master key battery replacement
• Pull the mechanical key out of the master
key
c::> page 33.
• 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
master key .
• Install the mechanical key.
@ For the sake of the environment
Dispose of dead batteries properly so as
not to poll ute 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 comp uter chip inside your key automatica lly
deactivates the electronic immobilizer when
the key is inside the vehicle. When you remove
the key from the vehicle, the electronic immo­
bilizer is automatically activated once again .
A WARNING
-
Always take the key with you when you
leave the vehicle. The key can disarm 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.
(D Tips
- Th e vehicle cannot be started if an unau­
thorized key is used. The vehicle may not
start if another radio device such as a key .,.

therefore best to avoid rough tracks and un ­
even terrain as much as possible . Also refer to
<=:> page 203.
A WARNING
Always adjust your driving to road and traf­
fic conditions. Do not let the extra safety
afforded by all-wheel dr ive tempt you into
taking extra risks.
- Although the all-wheel dr ive is very ef­
fective, a lways remember that braking
capacity is limited by t ire traction . Yo u
should therefore not dr ive at excessive
speeds on icy or slippery road su rfaces.
- On wet road su rfaces, be careful not to
dr ive too fast because t he fro nt wheels
c ou ld beg in to s lide on top of the wa ter
(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 ­
wheel drive vehicle. A lways drive at
speeds wh ich are suited to the road con­
ditions -risk of crash.
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 .
If a veh icle wit h a conventional energy system
i s not d riven for a lo ng pe riod o f time, the bat­
tery is discha rged by idling cu rrent co nsu mers
(e .g. immobilizer) . In ce rtain c ircumstances it
can result in there being insufficient ene rgy
avai lab le to start the engine .
I n tell igen t energy m anagemen t in your veh i­
cle hand les the d istribu tion of electrical ener­
gy . Starting ab ility is marked ly imp roved and
the life of the battery is extended.
B asically , energy management consists o f
battery diagnos is , idling current manage­
ment
and dynamic ene rgy man agement.
Int ellig ent technolog y 199
Battery diagnosis
Battery diagnosis continuously de termines
the state of the battery . Sensors de termine
batte ry voltage, battery current and battery
temperature . This determines the current
state of charge and the power of the battery.
Idling current management
Idling curren t management reduces energy
consumption while the vehi cle is standing.
With the ignition switched off, it controls the
energy supply to the various electrica l compo­
nents. Data from battery diagnos is is cons id­
ered .
Depending on the battery's state of charge,
i ndivid ua l cons umers are g radually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability .
Dynamic energy management
While the vehicle is being driven, dynamic en ­
ergy ma nagement distrib utes the energy ge n­
erated accord ing to the needs of the individ u­
al components . It regulates consum ption, so
that more electrical energy is not being used
than is being generated and ensures an opti­
mal state of cha rge for the battery .
(D Tips
-But even ene rgy management cannot
negate the limits of physics. Consider
t hat the powe r and life of a battery are
limited .
- If start ing ability is threatened , the indi­
cator light (•) appears
c::> page 17 .
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
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 ..,. •

286 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.
