Depending on the vehicle equ ipment level,
you may choose between the quartz clock or
the
GPS controlled clock* (!j in the radio or in
the MMI*. You can learn more about th is in
the MMI manual or in the radio user's manual.
Odometer /trip odometer
The display of distance dr iven is shown in kilo­
meters "km" or in miles "mi".
- USA mode ls - Miles
- Canada models - Kilometers
T he units of measure (kilometers/miles) can
be changed in the radio or
MMI*. You can learn more about this in the MM
I manual or in
the radio user's manual.
T he odometer @ shows the total number of
kilometers or miles that have been driven on
the vehicle .
The trip odometer @shows the distance driv­
en since it was last reset .
It can be used to

(D Tips
-
After the ignition is switched on, the pow­
er locking system switch and the unlocking button for the rear lid
cs in the door are
enabled.
Electronic immobilizer
The immobilizer prevents your vehicle from
being started by unauthorized persons .
Inside the key there is a computer chip . This
chip automat ically act ivates/deactivates the
electron ic immobilizer.
Applies to vehicles with ignition lock:
The electronic immobilizer deactivates auto­
matically when you insert the remote control
key into the ign ition lock . It activates again
automatically when you
remove the remote
control key from the ignition lock.
Applies to vehicles with convenience key:
If the remote control key is located inside the
vehicle and you press the
I S TART ENGI NE STOP I button, the electron ic
immobilizer deactivates automat ically .
If you
switch the ignition off and remove the remote
control key from the vehicle, the electronic
immobilizer activates again automatica lly. ..,.

_& WARNING
Always take the key with you when you
leave the ve hicle. The key can disarm the
electronic engine immobilizer and perm it
an unauthor ized person to start the engine
and enable ope rat ion of t he vehicle sys­
t ems such as power window or power sun­
roof leading to ser ious personal injury.
(D Tips
- The vehicle cannot be started if an unau­
thorized key is used . T he vehi cle may not
star t if another radio device such as a key
for another vehicle or a transponder is
l ocated on the key ring.

when the vehicle is moving.
- To help prevent poisonous exhaust gas
from being drawn into the vehicle, al­
ways keep the rear lid closed whi le driv­
ing. Never transport objects larger than
those which fit complete ly into the lug­
gage a rea, because then the rear lid can­
not be f ully closed.
- N ever leave your vehicle unattended es­
pecia lly with the rear lid left open.

be opened separately by pressing the but­
ton
e::5 on the master key. When you close
the rea r lid aga in, it locks automat ica lly.

192 Intelligent technology
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.
If a vehicle with a conventional energy system
is not driven for a long period of time, the bat­
tery is d ischarged by idling current consumers
(e.g. immobilizer). In ce rtain circumstances it
can result i n there bei ng insuff ic ient ene rgy
avai lab le to start the engine .
Intell igent energy management in your vehi­
cle hand les the d ist ribu tion of elect rical ener­
gy. Starting ab ility is mar ked ly imp roved and
the life of the battery is extended .
Basically , energy management consists of
batt ery diagno sis , idling curr ent manag e­
ment
a nd dynami c energy man agement .
Battery diagnosis
Battery d iagnosis continuously determ ines
the state of the battery . Sensors determ ine
battery vo ltage, battery current and battery
temperature . This dete rm ines the current
sta te of charge and the power of the ba ttery.
Idling current management
Idling current management reduces energy
consumption wh ile the vehicle is stand ing .
W ith the ignition switched off, it cont ro ls the
ene rgy s upply to the va rio us e lectrica l compo­
nents . Data from battery diagnosis is consid­
e red.
Depending on the battery's state of charge,
i nd ividua l consumers are grad ually t urned off
to p revent ex cess ive d isc harge of the ba ttery
and thus mainta in start ing capability.
Dynamic energy management
While the vehicle is be ing dr iven , dynamic en­
e rgy management dist ributes t he energy gen­
e rated accordi ng to the needs of the individu­
a l componen ts.
It reg ulates consump tion, so
that more electrical ene rgy is not being used than
is being generated and ensures an opti ­
mal state of charge for the battery.
(D Tips
- But even energy man ageme nt canno t
negate the limi ts of physics . Conside r
that the powe r and life of a battery are
limited .
- If start ing ability is threatened, the indi ­
cator light (•) appears ~
page 17.
What you should know
The highest priority is given to maintaining
starting capability .
The b attery is severe ly taxed in short -d istance
driv ing, in ci ty traff ic and during t he cold time
of yea r. Ab undant electrical energy is re­
quired, but on ly a little is generated . It is also
critical if the engine is not r unning and electri­
ca l components are turned on . In this in­
stance ene rgy is be ing consumed but none is
being generated .
It is in precisely these s ituations that you will
notice energy management active ly reg ulat­
ing the d istribution of energy.
Vehicle stand s for an e xtended period
If you do not drive your vehicle over a period
of several days or weeks, e lectrica l compo ­
nents are gradually cut back or sw itched off.
This reduces energy consumption and ma in­
ta ins start ing capability over a longer pe riod .
Some of the convenience functions may not
operate, such as the interior lights or the
power seat adjustme nt. The convenience
f unc tions wi ll be available again when yo u
swi tch on the igni tion and sta rt the eng ine .
With the engine turned off
If you listen to the radio, for examp le, w it h
the engine t urned off or use other MMI func­
t ions, t he battery is be ing discharged.
If starting capability is jeopardized due to en ­
ergy consump tion, the following warning ap-
pears in the MM I display: .,,.

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 se rious personal injury.
0 Note
If emergency repairs must be perfo rmed
elsewhere, have the ve hicle examined by
an authorized A udi dealer as soon as possi­
ble.
