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.

Depending on the way the vehicle is driven
and the operating conditions, oil consumption
can be up to a 1/2 quart per 600 mi les (0.5 li­
ter per 1,000 km) . Consumption may be high­
er within the first 3,000 miles (5,000 km).
@ Tips
The oil level indicator in the MMI* Display
is only an information display. If the oil
level is too low, a min imum oil warning ap­
pears in the instrument cluster. Add oil

• Top off the oil again, if necessary.
• Screw the cap back on the filling hole.
A WARNING ~
-Wh ile topping off, the o il must not come
in contact with hot engine parts -fire
hazard!
- The oil filler cap must be properly se­
cured to prevent oil from being sprayed
on the hot engine and exhaust system
when the engine is running -fire hazard!
- If your skin has come in contact with the
engine o il, you must subsequently
cleanse it thoroughly.
(D Note
-Check the oil level using the radio or
MMI*. If the message
Please reduce oil
level
appears, contact your authorized
Audi deale r or other qualified workshop
to have excess oil extrac ted if necessary.
- Audi does not recommend the use of oil
additives. They may damage the engine
and adversely affect your New Vehicle
Warranty.

CD Note
Never use a fast charger as a booster to
start the engine. This will seriously dam­
age sensitive electronic components, such
as control units, relays, radio, etc., as well
as the battery charger.
Battery replacement
The new battery must have the same specifi­
cations and dimensions as the original equip­
ment battery.
Intelligent energy management in your vehi­
cle is responsible for distributing the electri­
cal energy throughout your vehicle
c::, page 211. The intelligent energy manage­
ment system w ill keep the engine battery
charged bette r then ve hicles w ithout this sys­
tem. To ma ke sure t he addi tional e lectrical en­
ergy is available once again after you have
changed the battery, we recommend that you
install batteries of the same type and man u­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations are listed on the battery housing. Your
author ized Audi dealer must code the battery
i n the energy management system to enable
you to use the energy management functions
correctly after replac ing the bat tery .
If it is not possible to use a battery of this
type, the new battery must have the same ca­ pac ity, voltage (12 volts), amperage, con­
s truction and pl ug seal ing .
When insta lli ng the battery, make sure the ig ­
ni tion and all e lectr ica l cons umers are turned
off.

impair the vehicle's hand ling and stop­
ping ability .

272 T ire s and wheel s
- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, winter condit ions or un­
paved roads), the pressure monitor ind i­
cator may be delayed .
- Ask your author ized Audi dealer if run­
flat tires may be used on your veh icle.
Your vehicle regist rat ion becomes invalid
if you use these tires when not permit­
ted. Damage to your veh icle or acc idents
cou ld also resu lt.
(D Tips
- The tire pressure monitoring system
stops working when there is an ESP/ABS malfunction.
- Using snow chains may result in a system
malfunction.
- To ensure a proper TPMS function use AUDI O riginal Tires wh ich are marked
with "AO" or "RO" on the tire sidewall.
