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
battery is dead and has to be replaced. In
addition, when the battery is dead the
E!!
symbol appears in the instrument cluster
Opening and closing 33
display as well as the message: Please
change key battery .
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
maste r 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 original.
, 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 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 una u­
thorized key is used. The vehicle may not
start if another radio device such as a key

8_ WARNING
Always adjust your driving to road and traf­
fic condit ions. Do not let the extra safety
afforded by all-wheel dr ive tempt you into
taking extra r isks.
-Although the all-wheel dr ive is very ef­
fective, always remember that braking capacity is limited by ti re traction. You
should the refore not drive at excessive
speeds on icy or sl ippery road su rfaces.
- 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
(aquaplaning) . If this sho uld occur, you
will have no warning from a sudden in­ crease in engine speed as with a front­
wheel drive vehicle. Always 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 optimizes the
availability of electrical energy for starting the engine.
I f a vehicle with a conven tional energy system
is not driven for a long period of time, the bat ­
tery is discharged by idling current cons umers
(e .g. immobilizer) . In ce rtain circumstances it
can result in there being insufficient energy
avai lab le to start the engine.
I ntelligent energy management in your veh i­
cle handles the distribution of electrical ener­
gy . Starting ab ility is marked ly improved and
the life of the battery is extended.
Basically, energy managemen t consists o f
batter y di agno sis, idling current m an age­
ment
and d ynamic ene rgy man agement.
B attery diagnosis
Battery d iagnosis continuously dete rmines
the state of the battery. Senso rs determ ine
battery vo ltage, battery cur rent and battery temperature
. This determines the current
state of charge and the power of the battery.
Idling current manag ement
Idling cur rent management reduces energy
consumption while the vehi cle is standing.
With the ign ition switched off, it controls the
energy supp ly to the various electrical compo ­
nents . Data from battery diagnosis is consid ­
ered.
Depend ing on the battery's state of cha rge,
individual consumers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability.
Dynamic en ergy m anag em ent
While the vehicle is being driven, dynamic en­
ergy management distr ibutes the energy gen­
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 starting 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 severe ly 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
crit ical if the engi ne is not running and electri­
ca l components are turned on . In this in­
stance ene rgy is be ing consumed but none is
being genera ted.
It is in prec isely these s ituations that you will
notice ene rgy management active ly regu lat-
ing the d istribu tion of ene rgy.

292 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 veh icle 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.
