84 Warm and cold
With this setting, you attain maximum com­
fort in the least amo unt of time. Change this
setting, as des ired, to meet yo ur persona l
needs.
The climate controls are a combination of heating, venti lation and cooling systems,
which automatica lly reduce hum idity and cool
the air inside your vehicle.
The climate control automatically maintains a
temperature once it has been set . The tem­
perature of the air from the vents, fan speed
(air volume) and air distribution are also auto­
mat ically adjusted . The system also takes into
account strong sunshine so that manual ad­
justment is not necessary . So in almost all
cases,
autom atic mo de offers the best cond i­
tions for the comfo rt of the occupants at all
times of the year¢
page 86.
Please note the following :
Turn on the air cond itioner to reduce hum idity
in the vehicle . Th is also prevents the w indows
from fogging up.
When the outside temperature is high and the
a ir is very hum id,
conden sation from the
evaporator may drip under the vehicle. This is normal and does not indicate a leak .
If the outside temperature is low, the fan nor­
mally only switches to a h igher speed once
the eng ine coolant has warmed up sufficient­
ly .
The air conditioner temporarily switches off
when you drive off from a standstill using full
thrott le to save engine power.
The compressor also switches off if the cool­
ant temperature is too high, so that the en ­
g ine can be adequately coo led under extreme
loads.
Du st and pollen filter
The dust and pollen filter (a combined particle
fi lter and activated charcoal filter) reduces or
prevents outside air pollut ion (dust, or po llen)
from entering the vehicle . T
he dust and po llen fi lter must be changed at
the interva ls specified in your Mai ntenance
booklet , so that the air conditioner can prop­
erly work.
If you drive your vehicle in an area with a high
degree of air pollution, the filter may need to
be changed more frequently than specif ied in
your Audi Warranty
& Maintenance book let. If
in doubt, ask your authorized Audi Service Ad­
visor fo r advice .
Key recognition
The current climate contro l settings are auto ­
matically stored and assigned to the remote
key
Energy management
T o prevent the battery from being discharged
and to resto re the ba lance of energy, compo ­
nents which require large amo unts of energy
are temporarily cut back or switched off
¢ page 211. Heat ing systems in particular re­
quire a great deal of energy. If you notice, for
example, that the rear w indow heater is not
heating, then it has bee n tempora rily cut back
o r switched off by
energy managemen t.
These sys tems are available again as soon as
the energy balance has been resto red.
.&_ WARNING ~
Reduced visibi lity is dangerous and can
cause accidents .

- For safe d riving it is very impor tant that
all windows be free of ice, snow and con ­
densation .
- Comp lete ly fam iliari ze yourse lf with the
proper use and function of the heating
and venti lation system and especially
how to defog and defrost the w indows.
- Never use the windshield wipe r/washer
system in freez ing weather unt il you

176 Airbag system
There are some important things you have to
know to make sure that the effectiveness of
the system will not be impaired and that dis­
carded components do not cause injury or pol ­
lute the environment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an airbag
from deploying when needed or deploying an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel horn pad or airbag cover
or the instrument panel or modify them
in any way.
- Never attach any objects such as cu­
pholders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners could damage the airbag cover
or change the stiffness or strength of the
material so that the airbag cannot de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system .
- All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including the installation of audio
equipment, cellular telephones and CB
radios, etc .) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work­ shop.
- Never modify the front bumper or parts
of the vehicle body.
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi . -
Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer .
- The airbag system can be activated only
once. After an airbag has inflated, it
must be replaced by an authorized Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only
once . After an airbag has been deployed,
it must be replaced with new replace­
ment parts designed and approved espe­
cially for your Audi model version. Re­
placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only.
Make sure that any airbag service action
is entered in your Audi Warranty
& Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD .
-In accidents when an airbag is deployed,
the vehicle battery separates the alterna­
tor and the starter from the vehicle elec­
trical system for safety reasons with a pyrotechnic circuit interrupter.
- Work on the pyrotechnic circuit inter­
rupter must only be performed by a
qualified dealer -risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.
@ For the sake of the environment
Undeployed airbag modules and preten­
sioners might be classified as Perchlorate Material -special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/per­
chlorate. When the vehicle or parts of the restraint system including airbag modules
safety belts with pretensioners are scrap­
ped, all applicable laws and regulations
must be observed. Your authorized Audi

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 ag nosis, idlin g current man ag e­
m ent
and dyn ami c en ergy manage 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 determ 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 .
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 211
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:!) page 212,
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 .
Some of the convenience functions may not
operate, such as the interior lights or the power seat adjustment . The convenience
funct ions w ill be available again when you
tu rn o n the ign ition and start the engine.
With the eng ine tu rned off
If you listen to the radio, for examp le, w ith
the engine turned off or use other MMI func -
tions, the battery is be ing discharged.
