Fuel gauge
The fuel gauge works only when the ignition is
on.
When the needle reaches the red area, the
warning light in the instrument cluster will il­
luminate
9 page 32 li)J. This means you
have approximately 1.9 gallons (7 litres) of
fuel left in the tank.
Time to refuel!
The total tank capacity of your vehicle is listed in
9 page 239.
(D Note
Never run the tank completely dry! An ir­
regu lar supply of fue l can cause eng ine
misfiring and fuel could enter into the ex­
haust system. The catalyt ic converter
co uld then overheat and be damaged.

36 Opening and clo sing
The transmitter and battery are located in the
head of the remote control. The receiver is lo­
cated inside the vehicle. The maximum effec­
tive range depends on several things . Remem­
ber, if the battery is weak, the effective range
decreases .
If you need to replace the remote contro l, or if
you need to have it repaired, you must see
your authorized Audi dealer. Only then can
you use the key again .
@ Tips
-If the ignition is sw itched on, the remote
control system is deact ivated .

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 handles the d istribution of electrical ener­
gy. Starting ab il ity is markedly imp roved and
the life of the battery is extended .
Basically, energy management consists of
batt ery diagno sis, idlin g current man ag e­
m ent
and dyn ami c en ergy manag emen t.
Batter y diagnosis
Battery diagnosis continuously determines
the state of the battery . Sensors determ ine
battery vo ltage, battery current and battery
temperature. This determ ines the current
state of charge and the powe r of the battery.
Idling curr ent man agement
Idling current management reduces energy
consumption while the vehicle is stand ing .
W ith the ignition switched off, it cont ro ls the
energy s upply to the various electr ical compo ­
nents . Data from battery diagnosis is consid­
ered.
D epending on the batte ry's state of charge,
i nd ividua l consumers are gradual ly t urned off
to prevent excess ive d ischarge of the battery
and thus maintain starting capability .
Dynam ic 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 155
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, you are
informed by a warning
r::!)poge 156,
Driver notification in the instrument
cluster display.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severe ly taxed in short -distance
driving, in city traffic and during the cold time
of year. Abundant electrical energy is re­ quired, but only a little is generated .
It is also
critical if the engine is not running and electri­
cal 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 actively regulat ­
ing the d istribution of energy .
Vehicle stands for an e xtended peri od
If you do not drive your vehicle over a period
of several days or weeks, e lectr ical 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 .
Take into considerat ion that when you unlock
your vehicle, some convenience functions, such as the remote key or power seat adjust­
ment, may not be available . The conven ience
funct ions w ill be available again when you
tu rn o n the ignition and start the engine .
With the engine turned off
If you listen to the radio, for example, w ith
the engine turned off, the battery is being d is-
charged.

still functioning and they will draw energy
from the battery and drain it, for example, the
engine immobilizer . To prevent this, you can
e ither charge the battery occasionally to keep
it in good working condi tion or you can d is­
connect the negat ive cable on the battery .
Winter ope ration
During the winter months, battery capacity
tends to decrease as temperatures drop . This
is because more power is also consumed while
start ing, and the headlights, rear window de­
fogger, etc ., are used more often .
Avoid unnecessary power consumption, par­
ticularly in c ity traffic or when traveling on ly
short distances. Let your authori zed Audi
dealer check the capacity of the vehicle bat ­
tery before winter sets in
¢ page 192. A well
charged battery w ill not only prevent starting
p rob lems when the weathe r is cold, but will
a lso last longer .
Replacing b attery
The new battery m ust have the same capaci ­
ty, voltage (12 volts), amperage, construction
a n d p lug sealing, as the origina l batte ry. Spec­
ifications are listed on the batte ry housing.
Batteries specially developed by A udi f ulfill
the ma intenance, output, and safety require ­
ments.
When insta lling the bat tery , make sure the ig­
n ition and all e lectr ica l cons umers are sw itch­
ed
off ¢ (j) .
We recommend that you use ma intenance­
free or
cy cle-re sis tant /le ak -proof batteries
according to the standards TL 825 06 (from
December 1997) and VW 7 SO 73 (from Au ­
gust 200 1).
Replacing the battery should be ca rried by a
qua lified workshop. Please follow the instruc­
tions on the battery cover.
(D Note
- All work on t he battery requires techni­
ca l knowledge. Please contact an A udi
dealership or anothe r authorized facili ty
Checkin g and fillin g 189
for questions abo ut the batte ry - danger
of acid burns and exp losion hazard!
- T he battery must not be opened! Do not
try to change the battery's liquid level,
otherwise detonating gas will escape
from the battery - explosion hazard!
- The AGM battery in the luggage com­
partment cannot leak, because the elec ­
tro lyte for this battery is absorbed into a
special glass mat. This leak-proof battery
must not be replace with a convent iona l
battery.
- Make sure the ventilation hose on the
side of the battery is connected, other­
w ise fumes or battery ac id can leak out.
- Battery holder and terminals always
have to be secured correctly.
- Before all work on the battery follow the
warnings below ¢.&. in Working on the
battery on page 190.
@) For the sake of the environment
Because of the prob lem of proper disposal
of a battery, we recommend your author ­
ized Audi dealer change the battery for
you. Batteries contain sulfur ic acid and
l ead and must always be disposed of prop­
erly in compl iance with a ll environmental
regulat ions. Disposing of vehi cle batter ies
improperly is very dangerous to the envi ­
ronment. Make sure that the removed bat­
tery cannot overbalance, otherwise sulfu­ ric acid might escape!
(D Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the
vehicle battery shou ld be removed and
stored where it w ill not freeze. This will
prevent it from be ing damaged and having
to be replaced . •
