.. When you take your foot off the brake ped
al, the engine restarts. The indicator light
turns off.
Additional information
The engine wi ll switch off in the P, D, N and S
positions as well as in manua l mode . In the P
position, the engine wi ll also remain off if you
take your foot off the brake pedal. The eng ine
starts again when you select another se lector
lever pos ition and take your foot off the brake
pedal.
If you select the R pos ition during a Stop
phase, the engine will start again.
Shift from D to P quickly to prevent the engine
from start ing unintentionally when shift ing
through R .
You can determine for yourself if the eng ine
will stop or not by reducing or increasing the
amount of force you use to press the brake pedal. For example, if you only lightly press
on the brake pedal in stop-and and-go traffic
or when turni ng, the engine will not switch off
when the vehicle is stationa ry . As soon as you
p ress the brake down harde r, the eng ine will
switch off.

-Have the airbag system inspected by
your Audi dealer before transporting
anyone on the front passenger seat.
(D Tips
If the capacitive passenger detection sys
tem determines that the front passenger seat is empty, the frontal airbag on the
passenger side will be turned off, and the
PASSENGER AIR BAG OFF light will stay
on .
Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different places on your Audi. Installing,
removing, servicing or repairing a part in an
area of the vehicle can damage a part of an
airbag system and prevent that system from
working properly in a collision.
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 cup
holders 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.
Airbag system 163
- 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 deploy only once .
After an airbag has been deployed, it
must be replaced with new replacement
parts designed and approved especially
for your Audi model version. Replace ment of complete airbag systems or air
bag components must be performed by
qualified workshops only. Make sure that
any airbag service action is entered in
your Audi Warranty

therefore best to avoid rough tracks and un
even terrain as much as possible . Also refer to
<=:> page 203.
A 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
taking extra risks.
- Although the all-wheel dr ive is very ef
fective, a lways remember that braking
capacity is limited by t ire traction . Yo u
should therefore not dr ive at excessive
speeds on icy or slippery road su rfaces.
- On wet road su rfaces, be careful not to
dr ive too fast because t he fro nt wheels
c ou ld beg in to s lide on top of the wa ter
(aq uaplaning). If this sho uld occ ur, you
will have no warning from a sudden in
crease in engine speed as with a front
wheel drive vehicle. A lways drive at
speeds wh ich are suited to the road con
ditions -risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimi zes the
availability of electrical energy for starting the engine .
If a veh icle wit h a conventional energy system
i s not d riven for a lo ng pe riod o f time, the bat
tery is discha rged by idling cu rrent co nsu mers
(e .g. immobilizer) . In ce rtain c ircumstances it
can result in there being insufficient ene rgy
avai lab le to start the engine .
I n tell igen t energy m anagemen t in your veh i
cle hand les the d istribu tion of electrical ener
gy . Starting ab ility is marked ly imp roved and
the life of the battery is extended.
B asically , energy management consists o f
battery diagnos is , idling current manage
ment
and dynamic ene rgy man agement.
Int ellig ent technolog y 199
Battery diagnosis
Battery diagnosis continuously de termines
the state of the battery . Sensors de termine
batte ry voltage, battery current and battery
temperature . This determines the current
state of charge and the power of the battery.
Idling current management
Idling curren t management reduces energy
consumption while the vehi cle is standing.
With the ignition switched off, it controls the
energy supply to the various electrica l compo
nents. Data from battery diagnos is is cons id
ered .
Depending on the battery's state of charge,
i ndivid ua l cons umers are g radually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability .
Dynamic energy management
While the vehicle is being driven, dynamic en
ergy ma nagement distrib utes the energy ge n
erated accord ing to the needs of the individ u
al components . It regulates consum ption, so
that more electrical energy is not being used
than is being generated and ensures an opti
mal state of cha rge for the battery .
(D Tips
-But even ene rgy management cannot
negate the limits of physics. Consider
t hat the powe r and life of a battery are
limited .
- If start ing ability is threatened , the indi
cator light (•) appears
c::> page 17 .
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driv ing, in city traff ic and during the cold time
of year . Abundant electrical energy is re -
quired, but on ly 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 being consumed but none is
being generated.
It is in precisely these situations that you wi ll
notice energy management actively regulat
ing the distribut ion of energy .
Vehicle stands for an extended period
If you do not drive your vehicle over a pe riod
of severa l days or weeks, electrical compo
nents are gradually cut back or switched off.
This reduces energy consumption and main
tains starting capab ility over a longer period.
Some of the conven ience functions may not
operate, such as the inter ior lights or the
power seat adjustment. The conven ience
functions will be available again when you
switch on the ignition and start the engine.
With the engine turned off
If you listen to the radio, for example, with
the eng ine turned off or use other MMI func
tions, the battery is being discharged .
If starting capability is jeopardized due to en
ergy consumption, the following warning ap
pears in the MMI display:
Please start the engine soon or the system
will be turned off.
The warning indicates that the system will be
turned off automatically after 3 minutes. If
you wish to continue using the functions, you
have to start the engine.
With the engine running
Although elect rical energy is generated when
the vehicle is being driven, the battery can be
come discharged. This happens most ly when
little energy is being generated and a great
dea l consumed and the battery 's state of
charge is not optimal.
To bring the energy balance back into equili
brium, consumers which require especia lly
large amounts of energy are temporarily cut
back or switched off. Heating systems in par
ticular requ ire a great deal of energy. If you notice,
for example, that the heated seats* or
the heated rear window are not heating, they
have been temporarily cut back or switched
off. These systems will be available again as
soon as the energy balance has been restored.
You will also notice that engine id le speed has
been increased slightly. Th is is normal and not
a cause for concern. By increasing engine idle
speed the additional energy required is gener
ated and the battery is charged.
