• Push the battery holder carefully into the
master key. •
Insta ll the mechanica l key .
Please ch ange the k ey battery
If the indicator light!! turns on and the mes­
sage appears, the batte ry in the remote con­
tro l master key i s drained. We recommend
having the battery replaced by an autho rized
A udi dealer.
@) For the sake of the environment
Dispose of d ead batteries properly so as
not to pollute the environment.
(D Tips
The replacement battery must be the
same spec ification as the o riginal.
Electronic immobilizer
The immobilizer helps to prevent unauthor­
ized use of your vehicle .
A computer chip inside your key automatically
deact ivates the electron ic immobilizer when
the key is inside the veh icle. When you remove
the key from the vehicle, the ele ct ron ic immo­
bilizer is automati cally activated once aga in.
.8_ WARNING
A lways take the key w ith you when you
l eave the vehicle. The key can 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 leadi ng to se rious pe rsonal injury.
@ Tips
- The ve hicle cannot be started if an una u­
thorized key is used. The vehicle may not start if another radio device s uch as a key
for another ve hicle or a transponder is
located on the key ring.

Replacing wh eels/ tire s
Vehicles w ith All Wheel Dr ive must always
have tir es of the same size. Also avoid tires
with different tread depths. For details see
pag e¢
page 249 , N ew tires and replacing
tires and wheels .
Off-Road driving?
Your Aud i does not have enough ground clear­
ance to be used as an off -road vehicle. It is
therefor e best to avoid rough tracks and un ­
even terrain as much as possible . Also refer to
¢ page 198.
A WARNING
Always adjust your driving to road and traf­
fic condit ions . Do not let the extra safety
afforded by All Wheel Drive tempt you into
taking extra risks.
- Although the All Wheel Drive is very ef­
fective, always remember that braking
capacity is limited by t ire traction . Yo u
should the refore not dr ive at excessive
speeds on icy or s lippery road surfaces.
- On wet road su rfaces, be ca reful not to
dr ive too fast because the front wheels
cou ld beg in to s lide on top of the wa ter
(aquaplaning). 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 vehicle wit h a conventional energy system
i s not driven for a long period of time , the bat­
tery is discharged by idling cu rrent consumers
(e .g. immobilizer) . In certain circumstances it
can result in there being ins ufficient energy
avai lab le to start the engine.
Int ellig ent technolog y 195
Intelligent energy management in your vehi ­
cle hand les the distribution of e lectrica l ener­
gy. Start ing ability is marked ly improved and
the life of the b attery is extended.
Bas ica lly, energy management consis ts of
batte ry diagnosi s, idling cur rent m anage­
ment
and dynamic energ y management.
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 batte ry .
Idling current management
Id lin g cur ren t management reduces energy
consumption while the vehicle is standing.
With the ig nition switched off, it controls the
energy supply to the various electrical compo­ nents. Data from battery diagnos is is cons id­
ered.
Depend ing on the battery's state of cha rge ,
individua l cons umers are gradually turned off
to prevent excessive discharge of the batte ry
and th us maintain starting capability .
Dynamic energy manag ement
While the ve hicle is being driven, dynamic en ­
ergy management distrib utes the energy ge n­
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 .
@ Tips
-But even energy management cannot
negate the limits of physics. Consider
t hat the powe r and l ife of a battery are
limited.

cator light

286 Consumer Information
Technical Modifications
Our guidelines must be complied with when technical modifications are made .
Always consult an authori zed 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.
