Digital clock/GPS controlled clock*
Depending on the vehicle equ ipment level,
you may choose between the quartz clock or
the GPS controlled clock*
l!!j in the radio or in
the MMI*. You can learn more about this in
the MMI manual or in the radio user's manual.
Odometer/trip odometer
The display of distance driven is shown in kilo­
meters "km" or in miles "mi".
- USA mode ls - Miles
- Canada models -Kilometers
The units of measure (kilometers/miles) can
be changed in the radio or MMI*. You can
learn more about this in the MMI manual or in
the radio user's manual.
The odometer @ shows the total number of
kilometers or miles that have been driven on
the vehicle . T
he trip odometer @shows the distance driv­
en since it was last reset. It can be used to
measure short distances. The last d igit shows
distances of 100 meters or 1/10 of a mile.
T he trip odometer can be reset to zero by
pressing the reset button

Malfunction message
If there is a malfunct ion somewhere in the in­
strument cluster,
DEF will appear in the trip
odometer and w ill stay on. Contact your au­
thorized Audi dea ler to have the problem cor ­
rected.
Immobilizer
When the ignition is switched on, the data on
the ignition key are scanned automat ica lly.
If an unauthor ized key was used, SAFE is dis­
played permanently in the odometer display

.8, WARNING
Read and follow all WARNINGS ¢.&. in
General description on page 32.
(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.

c::> _&. .
_& WARNING
-
-After closing the rear lid, always p ull up
on it to make sure that it is properly
closed. Otherwise it could open suddenly
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.
A
child cou ld craw l in to the car thro ugh the
luggage compartment and pull the lid
shut, becoming trapped and unable to
get out. To reduce the risk of personal in­
jury, never let children play in or around
your veh icle. Always keep the rear lid as
well as the ve hicle doors closed when not
in use .
- Always ensure that no one is within
range of the rear lid when it is moving, in
particular close to the hinges -fingers or
hands can be pinched.
(D Tips
When the vehicle is locked, the rear lid can be opened separately by pressing the but­
ton
~ on the master key. When you close
the rea r lid aga in, it locks automat ica lly.

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 discharged by idling current consumers
(e.g. immobilizer). In ce rtain c ircumstances it
can result in there being insuff icient ene rgy
avai lab le to start the engine .
Intell igent energy management in your vehi­
cle hand les the d istribution of electrical ener­
gy. Starting ab il ity is markedly improved and
the life of the battery is extended.
Basically, energy management consists of
batt ery di agno sis, idlin g current man ag e­
m ent
and dyn ami c en ergy m anage ment .
Batter y diagnosis
Battery diagnosis continuously determines
the state of the battery . Sensors determ ine
battery vo ltage, battery current and battery
temperature. This dete rm ines the current
state of charge and the powe r of the battery.
Idling curr ent man agement
Idling current management reduces ene rgy
consumption while the vehicle is stand ing .
W ith the ignition switched off, it cont ro ls the
energy supply to the va rious electr ical compo ­
nents . Data from battery diagnosis is consid­
ered.
Depending on the battery's state of charge,
i nd ividua l consumers are gradual ly t urned off
to prevent excess ive d ischarge of the bat tery
and thus maintain starting capability .
Dynamic en ergy management
While the vehicle is being driven, dynamic en­
e rgy management dist ributes the energy gen­
e rated according to the needs of the individu­
a l components.
It reg ulates cons umption, so
that more electrical energy is not being used
Int ellig ent technolog y 193
than is being generated and ensures an opti ­
mal state of charge for the battery.
(0 Tips
- But even energy management canno t
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 (•)
;:i ppears ~ page 17.
What you should know
The highest priority is given to maintaining
starting capability.
T he bat tery is severe ly taxed in short-distance
driving, in city traffic and during the cold time
of year. Ab undant electrical energy is re­
quired, but on ly a little is generated .
It is also
critica l if the engine is not running and electri­
ca l components are turned on . In this in­
stance energy is be ing consumed but none is
being generated .
It is in precisely these situations that you will
notice energy management active ly regulat­
ing the d istribution of energy.
V ehicle stand s for an ex tend ed peri od
If you do not drive your vehicle over a period
of severa l days or weeks, e lectrica l compo­
nents are gradually cut back or switched off.
This reduces energy consumption and ma in­
ta ins start ing capability over a longer period .
Some of the convenience functions may not
operate, such as the interior l ights or the
power seat adjustme nt. The convenience
funct ions w ill be available again when you
swi tch on the ignition and sta rt the eng ine .
With the eng in e turn ed off
If you listen to the radio, for example, w ith
the engine tu rned off or use other MMI func­
tions, the battery is be ing d ischarged.
If starting capability is jeopardized due to en ­
ergy consumption, the following warning ap- pears in the MM I display: ..,.

2 78 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 serious personal injury.
(D Note
If emergency repairs must be performed
elsewhere, have the vehicle examined by
an authorized A udi dealer as soon as possi­
ble.
