120 watts.
Before you purchase any accessories, always
read and follow the information in
¢ page 287, Additional accessories and ports
replacement.
& WARNING
The sockets and the electrica l accessories
connected to them operate only when the
ignition is switched on . Incorrect usage
can lead to serious injuries or burns. To re­
duce the risk of injuries, never leave chil­
dren unattended in the vehicle with the ve­
hicle key.
(D Note
To avoid damaging the socket, only use
plugs that fit properly.
- Never connect equipment that generates
electrical current, such as a so lar panel
or battery charger, to the 12-volt socket.
This could damage the vehicle's electri ­
cal system .
- The 12-volt socket should only be used
for a short period of time as a power
source for electr ical equipment . Please
use the electrical sockets in the vehicle
when connecting equipment for longer
periods .
- To avoid damaging the socket, only use
plugs that fit p roperly .
(D Tips
When the engine is off and accessor ies are
still plugged in and are on, the vehicle bat­
tery can still be drained .

-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 161
- 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
& Maintenance book­
let under
AIRBAG REPLACEMENT RE­
CORD .
-For safety reasons in severe accidents,
the alternator and starter are separated
from the vehicle battery with a pyrotech­
nic circuit interrupter.

A WARNING ,~
Always adjust your driving to road and traf­
fic conditio ns. Do not let the extra safety
a ff orded by all-wheel dr ive tempt you into
taking extra risks.
-Although the all-wheel dr ive is very ef­
fec tive, a lways remember that b raking
capacity is limited by t ire traction . You
sho uld the refore no t dr ive at excess ive
speeds on icy or sl ippery road surf aces.
- On wet road su rfaces, be careful not to
dr ive too fast because the front wheels
cou ld beg in to slide on top of the water
(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
whee l drive vehicle. A lways drive at
speeds wh ich are suited to the road con­
ditions - risk of c rash.
Energy management
Starting ability is optimized
E nergy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting the engine.
If a veh icle wit h a conven tional energy system
is not d riven for a long period of time , the bat ­
tery is discha rged by idling c urre nt cons umers
(e .g. immobilizer) . In certain circumstances it
can result in there being ins ufficient ene rgy
avai lab le to start the engine.
I ntell igent energy ma nagement in your vehi­
cle hand les the d istribution of electrical ener ­
gy . Starting abi lity is mar ked ly improved and
the life of the battery is extended .
B asically, energy management consists o f
battery diagno sis , idling current manage­
ment
and dynamic ene rgy man agement.
Battery diagnosis

temperature . This de termines the current
state of charge and the power of the battery.
Idling current management
Idli ng cur ren t management reduces energy
consump tion while the vehi cle is st anding.
With the ig nition switched o ff, it controls the
energy supply to the various electrical compo­
nents . Data from batte ry diagnosis is consid ­
ered.
Depend ing on the ba ttery's state of cha rge,
individual consumers a re g radually turned off
to prevent excessive discharge of the battery
and th us maintain starting capability.
Dynamic energy management
While t he vehi cle is being dr iven, dyn ami c en­
ergy management distr ib utes the energy gen ­
erated according to the needs of the individ u­
al components. It regulates consumption, so
that more e lectrical energy is not being used
than is being generated and ensures an opti­
mal state of charge for the battery.
(D Tips
- But even energy management cannot negate the limits of physics. Consider
that the power and life of a battery are
lim ited.
- If start ing ability is t hreatened, the indi­
cator light(•] appears ¢
page 17.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severe ly taxed in s hort-distance
driv ing, in city traff ic and during the cold time
of year. Ab undant electrical energy is re­
quired, but on ly a little is generated .
It is also
crit ical if the engi ne is not r unning and elec tri­
ca l components are tu rned on . In this in­
s tance ene rgy is be ing consumed b ut none is
being genera ted.
It is in precisely these situations that you will

198 Intelligent technology
Vehicle stands for an e xte nded period
If you do not drive you r vehicle over a pe riod
of several days or weeks, elec trical compo ­
nents are grad ually cut back or switched off.
This reduces energy cons umption and main­
tains starting capab ility over a longer period.
Some of the conven ience f unctions may not
ope rate, such as the inter ior lights or the
power seat adjustment. T he conven ience
f u nctions w ill be ava ilable again when you
switch on t he ignit io n and start the engi ne.
With the engine turned off
If you listen to t he radio, for example, with
the eng ine turned off or use othe r MMI func­
tions, the battery is b eing d ischa rged .
I f starting capab ility is jeopa rdized due to en­
ergy consumpt ion, the following warning ap­
pears in the MMI disp lay:
Please start the engine soon or the system
will be turned off.
T he warning ind icates that the system will be
turned off automatically afte r 3 m inutes. If
you wish to cont inue using the f unctions, you
have to start the engine.
With the engine running
A ltho ugh elect ric al e nergy is genera ted when
the veh icle is being driven, the bat tery can be ­
come d ischarged. This ha ppens most ly w hen
litt le energy is be ing generated and a great
deal consumed and the battery 's state of
charge is not optimal.
To br ing the ene rgy balance back into equili­
brium, cons umers which require especially
large amo unts of energy are temporarily cut
back or switched off. Heating systems in par­
ticular requ ire a great dea l of energy. If you
n otic e, fo r example, that the heated seats * or
the heated rea r window a re not heat ing, t hey
h ave been te m po rar ily cu t bac k or swi tched

soon as the energy ba lance has been restored .
You will a lso not ice that engin e idl e spe ed has
been in cr eased sligh tly. This i s norm al and no t
a ca use fo r con cern. By incre asin g engi ne idle speed
the a dditional energy requi red is gener ­
ated and the battery is charged.

226 Check ing and filling
- Always disconnect the battery.
- Never smoke or work near heaters or open flames . Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and persona l in ­
jury while the engine is running or being started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repa ir
with the engine running:
- Fi rst, fully apply the parking bra ke,
move se lec to r lever to P (Pa rk) .
- Always use extreme caution to preven t
clot hing, jewe lry, or long h air from ge t­
ting caught in the radiator fan, V -belts
or other moving parts, or from contact­ ing hot parts. Tie back hair before
start ing, and do not wear cloth ing that
will hang or droop into the eng ine.
- Min imize exposure to emission and
