40 Opening and clo sing
@ Tips
Please note that the current state of the
veh icle door locks can only be recalled with
the master key that was last used to lock
the vehicle . It is possible that a different
state is shown for the door locks on the
other master key wh ich is not the same as
that of the vehicle .
Master key battery replacement
Each master key contains a battery housed
under the cover .
Fig. 30 Master ke y: opening the cove r
.. Pry apart the base q fig. 30@ and the cover
@ carefully with a coin.
.. Remove the cover (arrow) .
.. Remove the dead battery from the cover.
.. Install the new battery. Please make certain
that the" +" sign on the battery faces down
in the cover . Correct polarity is shown on the
cover .
.. Place the cover with the new battery on the
key base and press both parts together.
@ For the sake of the environment
Dispose of dead batteries properly so as
not to po llute the environment.
@ Tips
The replacement battery must be the
same specification as the or iginal.
Electronic immobilizer
T he immobilizer helps to prevent unauthor
ized use of your vehicle .
A computer chip in side your key automatically
deac tivate s the elec tronic immob ilizer when
you insert the key in the ignition lock , or on
vehicles with Convenience key*, when the key
is ins ide the veh icle. When you remove the key
from the ignition lock, or on vehicles with
Convenience key, when you remove the key
from the vehicle, the electronic immobilizer is
automatica lly activated once again.
WARNING
Always take the key with you when you
l eave the vehicle. The key can disarm the
electronic engine immobilizer and permit
an unauthorized person to start the engine
and enable operation of the vehicle sys
tems such as power w indow or Panoramic
slid ing sunroof* leading to serious person
al injury.
u) 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
for another vehicle or a transponder is
located on the key ring.

Replacing wh eels/ tire s
Vehicles w ith all-wheel drive must a lways
have tires of the same size. Also avoid tires
with different tread depths. For details see
page ¢
page 284, New tires and replacing
tires and wheels .
.&_ 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
tak ing extra risks.
-Although the all-wheel dr ive is very ef
fective, always remember that braking
capacity is limited by t ire traction . You
sho uld therefore not dr ive at excessive
speeds on icy or s lippery road surfaces.
- On wet road su rfaces, be careful not to
dr ive too fast because t he front wheels
cou ld beg in to s lide on top of the wa ter
(aquaplaning). If this sho uld occ ur, you
w ill 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
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting
the engine.
I f a vehicle w it h a conventional energy system
i s not driven for a long pe riod of time, the bat
tery is disch arged by idling c urrent cons umers
(e .g. immobilizer) . In ce rtain c ircumstances it
can result in there being insufficient energy
ava ilab le to start the engine .
I n tell igen t energy management in your vehi
cle hand les the d istribution of electrical ener
gy . Starting abi lity is marked ly imp roved and
the life of the battery is extended.
Int ellig ent technolog y 229
Basica lly, energy management consis ts of
batte ry diagnosi s, idling cur rent manage
ment
and dynamic energy management.
Battery diagnosis
B attery diagnosis continuously de termines
the state of the battery . Sensors determine
batte ry voltage, battery current and battery
temperature . This determines the current
state of charge and the power of the battery.
Idling current management
Id lin g cur ren t man agement reduces energy
consumption while the vehi cle 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,
individual cons umers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability.
Dynamic energy manag ement
While the vehicle 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 be ing generated and ensures an opti
mal state of charge for the battery .
(D Tips
-But even e nergy management cannot
negate the limits of physics. Consider
t hat the powe r and l ife of a bat tery are
l imited.
- If start ing ability is threatened, you are
informed by a warning ¢

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 ifi ca
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.
