If the message does not turn off, have your a u­
thor ized Audi dealer or qualified wo rkshop cor­
re ct the malfunction .
~ Engine
• Engin e stopp ed: No power steering and
brake support .
There is a malfunction in the eng ine or in the fue l
supp ly system .
A large amount of steering and braking force is required when driving a rolling vehicle with the
e ng ine stopped . Try to stop a rolling vehicle ca re­
fu lly on the side of the road. See your autho riz ed
Aud i deale r or qualified repair facility.
A WARNING
-
If the eng ine stops while dr iving, a la rge
amount of braking force is req uired . This in­
creases the risk of an accident. As long as the
vehicle rolls with the ignition switched on and there is enough battery charge, the powe r
steering will still work . If not, a la rge amount
o f stee ring force is requ ired .

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, servic ing or repa iring a part in an area of the
vehicle can damage a part of an airbag system
and p revent that system from working properly
in a co llision.
There are some important things you have to
know to make su re that the effectiveness of the
system w ill not be impaired and that discarded
components do not cause injury or pollute the
environm ent .
A WARNING
Improper care, serv icing and repa ir proce­
dures can increase the risk 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 cup holders or telephone mountings to the surfaces cov­
er ing the airbag units.
- For cleaning the horn pad or instrument
pane l, use on ly 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 material so
that the airbag cannot dep loy and protect
properly.
- Never repair, adjust, or change any parts of
the airbag system.
- All work on the steering 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.
- For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechnic circ uit
interrupter.
- Wo rk on the pyrotechnic c ircuit inte rrupt­
er must on ly be performed by a qua lified
dealer -risk of an acc ident!
- If the vehicle or the circuit interr upter is
scrapped, all applicable safe ty p recau tions
mus t be followed.

Smart Technology
ignition switched off, it controls the energy sup­
p ly to the various electrical components. Data
from battery diagnosis is considered.
Depending on the battery's state of charge, indi­
vidual consumers are gradually turned off to pre ­
vent excessive discharge of the battery and thus maintain starting capability.
Dynamic energy management
While the vehicle is being driven, dynamic energy
management distributes the energy generated
according to the needs of the individual compo­
nents.
It regu lates consumption, so that more
electrical energy is not being used than is being
generated and ensures an optimal state of
charge for the battery.
(D Tips
- But even energy management cannot neg­
ate the limits of physics . Cons ider that the
power and life of a battery are limited.
- If starting ability is threatened, the indica­
tor light (•) appears
9 page 15, Cl Battery.
What you should know
The highest priority is given to maintaining start­
ing capability .
The battery is severely taxed in short-distance
driving, in city traffic and during the cold time of
year. Abundant electrical energy is required, but
only a little is generated . It is also crit ica l if the
engine is not running and electrical components
are turned on . In this instance energy is be ing
consumed but none is being generated .
It is in precisely these situations that you will no­
tice energy management actively regulat ing the
d istr ibut ion of energy .
Vehicle stands for an extended period
If you do not driv e your vehicle over a period of
several days or weeks, electrical components are
gradually cut back or switched off. This reduces
energy consumption and ma inta ins starting ca­
pability over a longer period . Some of the con­
ven ience funct ions may not operate, such as the
interior l ights or the power seat adjustment. The
196
convenience functions will be availab le again
when you switch on the ignition and start the en­ gine.
With the engine turned off
If you listen to the radio, 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 indicates that the system will be
switched off automat ically in a moment . If you
wish to cont inue using the functions, you have to
start the engine.
With the engine running
Although electrica l 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 deal con ­
sumed and the battery's state of charge is not
opt imal.
To bring the energy balance back into equilibr i­
um, consumers wh ich require espec ially large
amounts of energy are temporarily cut back or
switched off. Heating systems in particular re­
quire a great dea l of energy. If you notice , fo r ex­
amp le, that the heated seats* or the heated rear
window are not heating, they have been tempo­
rarily cut back or switched off. These systems will
be available aga in as soon as the energy balance
has been restored.
You will also notice that engine idle speed has
been increased slig htly. This is norma l and not a
cause for concern . By increasing engine idle
speed the additional energy required is generat­
ed and the battery is charged.

Check ing and F illing
warm water and baking soda to neutralize
the acid.
CD Note
Never use a fast charger as a booster to start
the engine . This will serious ly damage sensi­
tive electronic components, such as control
units, relays, radio, etc., as well as the battery
charger.
Battery replacement
T he new battery must have the same specifica­
t ions and dimensions as the original equipmen t
bat tery.
Int elli g ent en ergy managem ent in your vehicle is
responsible for distributing the electrical energy
throughout your vehicle
r=> page 195. The intelli­
gent energy management system will keep the
engine battery charged better than veh icles w ith­
out this system . To make sure the addit ional
e lectrical energy is avai lab le once again after you
have changed the battery, we recommend that
you install batteries of the same type and manu­ facture on ly (the same as those installed at the
time your vehicle was delivered). Specifications
are listed on the battery housing. Your author­
i z ed dealer must code the battery in the energy
management system to enable you to use the en­
ergy management functions correctly after re ­
placing the battery .
The new battery must have the same capacity,
voltage (12 volts) , amperage, construction and
plug sealing .
When installing the battery, make sure the igni­
tion and all electrical consumers are sw itched
off.
CD Note
- Make sure the ventilation hose on the s ide
of the battery is connected, otherw ise
fumes or battery ac id can leak out.
- Vehicles with the Start-Stop-System* are equipped with a special cycle-proof AGM battery . Installing a d ifferent type of bat­
tery can cause problems in the vehicle elec -
234
trical system. When replacing the vehicle
battery, always install one with the same
specifications as the original battery .
- Battery mounts and clamps m ust always be
secured correctly.
- Read and follow the warnings under
¢ page 231, Working on the battery before
performing any work on the battery .
@ For the sake of the environment
Because of the p roblem of proper disposal of
a battery, we recommend your authorized
A udi dealer change the battery for you . Bat­
teries contain sulfur ic acid and lead and must
a lways be disposed of properly in compliance
with all environmental regulations . Disposing
of veh icle batteries improperly is very danger­
ous to the environment .
