@ Tips
If your vehicle has been standing for an ex ­
tended period, please note the following:
- The proximity sensors are deactivated after
a few days to save power. You then have to
pull on the door handle once to unlock the
vehicle and a second time to open the vehi­
cle.
- To p revent the battery from being dis­
charged and to preserve your vehicle's abili­
ty to start for as long as possible, the ener­
gy management system gradua lly switches
off unnecessary convenience functions. It is
possible that you will not be ab le to unlock
your vehicle using these convenience func­
tions .

You can manually stop the a utomat ic opening/
closing of the luggage compartment lid. The au­
tomatic closing process begins if you push down
on the rear lid.
A WARNING
- Never close the rear lid inattentively or with­
out checking first . Although the closing
Op ening and cl osing
force of the rear lid is limited, you can still
seriously injure yourself or others.
- Always ensure that no one is within range of
the rear lid when it is moving, in particu lar
close to the hinges and the upper and lower
edges - fingers or hands can be pinched.
- To help prevent poisonous exhaust gas from
be ing drawn into the vehicle, a lways keep
the rear lid closed while dr iving. Never
transport objects larger than those which fit
comp letely into the luggage area, because
then the rear lid cannot be fully closed.
- Never leave your veh icle unattended espe­
cially with the rear lid left open. A child
could crawl into the car through the luggage
compartment and pull the lid shut, becom­
ing trapped and unab le to get out. To re­
duce the risk of personal in jury, never let
children play in or around your vehicle . Al­
ways keep the rear lid as we ll as the veh icle
doors closed when not in use .
- If there is a luggage rack or bicycle rack
mounted on the rear lid, it may not be able
to open comp letely or an opened rear lid
may close by itself because of the added
weight . So the open rear lid must be sup­
ported or the we ight must be removed from
the l uggage rac k first.
(!) Tips
- When the vehicle is locked, the rear lid can
be unlocked separately by pressing the but­
ton~ on the master key . When the rear lid
is closed again, it locks automatically.
- The following applies to vehicles equ ipped
w ith the convenience key* feature : if the re­
mote contro l key is left in the luggage com­
partment , luggage compartment will auto­
matically unlock itse lf after you lock the ve ­
hicle. This prevents you from unintentiona l­
ly locking your key in the luggage compart­
ment.
- If the vehicle battery charge drops below a
certain level, you can still open or close the
rear lid manually, however, you will need to
app ly more force to close it.

Repair , care and disposal of the airbags
Parts of the a irbag system are installed at many
d ifferent p laces on your Aud i. Installing, remov­
ing, servicing o r repa iring a part in an area of the
vehicle can damage a pa rt of an airbag system
and prevent that system from working properly in a co llision.
There are some importa nt things you have to
know to make sure that the effectiveness of the
system w ill not be impaired and that discarded
components do not cause injury or pollute the
environment.
A WARNING
Improper care, serv icing and repair proce­
dures can increase the r isk of personal injury
and death by preventing an airbag from de­
ploying when needed or deploying an airbag
unexpectedly :
-
-Never cover, obstruct, or change the steer­
ing wheel horn pad or a irbag cover or the in ­
strument panel or mod ify them in any way .
- Never attach any objects such as cupholders
or telephone mountings to the surfaces cov­
er ing the airbag units .
- For cleaning the horn pad or instrument panel, use only a soft, dry cloth or one mois­
tened with plain water. Solvents or cleaners
cou ld damage the a irbag cover or change
the stiffness or strength of the mater ial so
that the airbag cannot dep loy and protect
properly.
- Never repair, adjust, or change any parts of
the airbag system.
- All wo rk on the stee ring wheel, instr ument
pane l, front seats or electrical system (in­
cluding the installation of audio equipment,
cellu lar telephones and CB radios, etc .)
must be performed by a qualified technician
Airb ag sys tem
who has the training and special equ ipment
necessary.
- For any wo rk on the airbag system, we
strong ly recommend that you see your au­
thorized Audi dealer or qualified workshop .
- Never modify the front bumper or parts of
the vehicle body.
- Always make sure that the side a irbag can
inflate without interference:
- Never install seat covers or replacement
upholstery ove r the front seatbacks that
have not been specifica lly approved by
Audi .
- Never use addi tional seat c ushions that
cove r the areas where the side airbags in­
flate.
- Damage to the orig inal seat cove rs or to
the seam in the area of the s ide airbag
module must a lways be repaired immedi­
ate ly by an authorized Aud i dealer.
- The airbag system can be activated only
once . A fter an airbag has inflated, it must
be replaced by an authorized Audi dealer or
qualified technic ian who has the technical
information, t raining and spec ial equ ipment
necessary.
- The airbag system can be deployed only
once . After an airbag has been deployed, it
must be replaced with new rep lacement
parts des igned and approved especially for
your Aud i model version. Replacement of
comp lete airbag systems or airbag compo­
nents must be performed by qualified work­
shops only. Ma ke sure that any airbag serv­
ice act ion is en tered in your Aud i Wa rranty
& Maintenance booklet under AIRBAG RE ­
PLACEMENT RECORD.
- In accidents when an airbag is dep loyed, the
vehicle battery separates the alternator and
the starter from the veh icle electrical sys­
tem for safety reasons w ith a pyrotechnic
circu it interrupter.
- Wo rk on the pyrotechnic c ircuit inte rrupt­
er must on ly be performed by a qu alified
dealer -risk of an acc ident!
- If the vehicle or the circuit interr upter is
scrapped, all applicable safe ty p recautions
must be followed .

0 ::..:: co ..... ..... Starting ability is marked ly improved and the life
of the battery is extended.
Basically, energy management consists of
bat ­
t e ry di agno sis, idl ing curr ent mana gement
and
dy namic en ergy management .
Battery diagnosis
Battery diagnosis continuous ly determines the
state of the batte ry . Sensors dete rm ine battery
voltage, batte ry current and battery tempera­
ture . This determ ines the current state of charge
and the power of the battery.
Idling current management
Idling current management reduces energy con­
sumpt io n while the veh icle is stand ing . With the
i gn it ion sw itched off, it controls the energy sup­
p ly to the various ele ctrical components . Data
from battery diagnosis is considered.
D epending on the battery's state of charge, ind i­
vid ual consume rs a re gradually turned off to p re­
vent excessive discharge of the battery and thus
maintain starting capability.
Dynam ic energy management
While the vehicle is being driven, dynamic energy
management dist ributes the ene rgy generated
accord ing to the needs of the individual compo ­
nents . It regulates cons umption, so that mo re
e lectrica l energy is not being used than is being
generated and ensures an optimal state of
charge for the battery.
@ Tips
- But even energy management cannot neg­
ate the limits of physics. Consider that the power and life of a battery are limited.
- If starting ability is threatened, the indica­
tor light
(•j appears 9 page 16.
What you should know
The highest priority is given to maintaining start­
ing capability.
The ba tte ry is severely taxed in short -d istance
driving, in city traffic and d uring the co ld time of
year. Abundant electrical energy is requ ired, but
Intellig ent Technology
on ly a little is generated . It is a lso critical if the
engine is not running and electrical components
are turned on. In this instance energy is being
consumed but none is being generated.
It is in precisely these situations that you will no ­
tice energy management actively regulating the distribution of energy .
Vehicle stands for an extended period
If you do no t drive your vehicle ove r a period of
severa l days o r weeks, electrical components are
gradually cut back or switched off. This reduces
energy consumption and maintains starting ca ­
pability over a longer period. Some of the con­
venience functions may not operate, such as the interior lights or the power seat adjustment. The
convenience functions will be ava ilable aga in
when you switch on the ignition and start the en­
gine.
With the engine turned off
If you listen to the rad io, for example, with the
engine turned off or use other MMI funct ions,
the battery is being d ischarged .
If starting capab ility is jeopardized due to energy
consumption, a message appears in the MMI dis­
play . The message ind icates that the system will
be switched off automat ica lly in a moment . If
you w ish to continue using the funct ions, you
have to sta rt the eng ine.
With the engine running
Although e lectr ical energy is generated when the
vehicle is being driven, the battery can become
discharged. This happens mostly when little en­
ergy is being generated and a great dea l con­
s u med and the batte ry's state of charge is not
optimal.
T o bring the energy balance back into equilibr i-
um, consumers w hich require espec ia lly large
amounts of ene rgy are tempo rar ily cut back o r
swi tched off . Hea ting systems in particular re-
quire a great de al of energy. If yo u no tice, fo r ex­
amp le, that the heated seats * or the heated rear
window are not heating, they have been tempo ­
rarily cut bac k or switched off. These systems will .,..

Intelligent Technology
be ava ilab le aga in as soon as the energy balance
has been restored.
You will a lso not ice tha t engine idle speed has
been inc reased slightly. This is normal and not a
cause for concern. By increasing eng ine idle
speed the additiona l energy required is generat ­
ed and the battery is cha rged .
