Improperly worn safety belts
Incorrectly positioned safety belts can cause
severe injuries.
Wear ing sa fe ty be lts imprope rly can cause se ­
rio us in jury or death. Safety be lts can only
wo rk when they are correct ly positioned on
the body. Improper seating positions reduce
the effect iveness of safety belts and w ill eve n
increase the r isk of injury and death by mov­
in g the safety belt to cr itical a reas of the
body. Imprope r seat ing pos itions also in­
crease the risk of serio us in jury and death
when an air bag deploys and strikes an occu ­
p a nt who is not in the cor re ct seating posi­
tion. A driver is responsib le for the sa fe ty of
all vehicle occupants and especially for chi l­

Airbag system Important things to know
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints . For
airbags to do their job, occupants must al­
ways properly wear their safety belts and be
in a proper seating position.
F or your safety and the safety of your passen­
gers, before driving off, always:
"" Adjust the driver's seat and steering wheel
properly¢
page 134,
"" Adjust the front passenger's seat properly
¢ page 59,
""Wear safety be lts properly ¢ page 146,
""Always properly use the proper child re-
stra int to protect ch ildren
r::::> page 174.
In a collision, airbags must inflate within the
blink of an eye and with considerable force.
The supplementa l airbags can cause injuries if
the dr iver or the front seat passenger is not
seated properly . T herefore in order to help the
a irbag to do its job, it is important, both as a
d river and as a passenge r to s it properly at all
times.
By keep ing room between your body and the
steer ing whee l and the front of the passenge r
compartment, the airbag can i nflate fully and
comp lete ly and provide supp lemen tal protec­
tion in ce rtain frontal collisions

There is a lot that the d river and the passen­
gers ca n and must do to help the individua l
safety features ins talled in your A ud i work to­
gether as a system.
P rope r seat ing pos ition is important so that
the front airbag on the dr iver s ide ca n do its
job. If yo u have a physical impa irment or con-
A irbag system 15 1
dition that prevents yo u from sitting properly
o n the driver seat with the safety belt properly
fastened and reach ing the peda ls, or if you
have concerns with regard to the function or
operation of the Advanced Airbag System,
please contact your author ized Audi dealer or
qualified wo rkshop, o r call Audi Customer Re­
l ations at 1-800-822-2834 fo r poss ible modi­
ficat io ns to your veh icle.
When the airbag system dep loys, a gas gener ­
ator will fill t he a irbags, break open the pad­
ded cove rs, and inflate between the steer ing
whee l and the dr ive r and between the instru­
ment pane l and the fron t passenger. The a ir­
bags will deflate immedia tely after dep loy­
ment so that the front occupants can see
thro ugh the windshie ld again witho ut inter­
ruption.
A ll of th is takes place in t he blink o f an eye, so
f ast that many people don't even realize that
the airbags have deployed. The airbags a lso
inflate with a great dea l of force and nothing
should be in their way when they deploy.
Front a irbags in combination with properly
wor n safety belts slow down and lim it the oc ­
c u pant's fo rward movement. Togethe r they
help to preve nt the drive r and front seat pas­
senger from h itti ng pa rts of the inside of the
vehicle while reducing the forces act ing on the
occupant dur ing the crash . In this way they
help to reduce the risk of injury to the head
and upper body in the crash. Airbags do not
protect the arms or the lower parts of the
body.
Both front airbags wi ll not inflate in all fronta l
collisions . The trigge ring of the airbag system
depends on the vehicle dece lerat ion rate
ca used by the co llision and registered by the
electron ic control unit. If t his rate is below
the reference value programmed into the con ­
tro l unit, the airbags will not b e trigge red,
even t hough the car may be bad ly damaged as
a res ult of the co llision . Ve hicl e damage, re­
pair costs or even the lack of ve hicle damage
is not necessarily an indica tion of whether an
airbag should inflate or not . .,. •

Q page 162, PASSENGER AIR BAG OFF light.
A lways remember, a chi ld seat or infant carr i­
e r i nsta lled on the front seat may be struck
and knocked out of position by the rapidly in ­
flating passenger's airbag in a frontal colli­
sion. The airbag could greatly reduce the ef­
fectiveness of the chi ld restraint and even se­
riously injure the child during inflat ion.
F or this reason, and because the back seat is
the safest p lace for chi ldren -when properly
restra ined accord ing to their age and si ze -we
strongly recommend that children always sit
in the back seat
Q page 174, Child Safety .
A WARNING
A child in a rearward-facing child seat in­
stalled on the front passenger seat will be
ser iously injured and can be killed if the
front airbag inflates -even with an Ad­
vanced Airbag System.
- The inflating a irbag will hit the child seat
or infant carrier w ith great force and w ill
smash the ch ild seat and child against
the backrest, center armrest, door or
roof .
- Always install rear -facing child seats on
the rear seat .
- If you must install a rearward facing
child seat on the f ront passenge r seat
because of except iona l circumstances
and the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately i nstall the rear-facing chi ld seat in a
rear seating position and have the airbag
system inspected by your Aud i dealer .
- Forward-fac ing ch ild seats installed on
the front passenger's seat may interfere
with the deployment of the airbag and c ause se rious pe rsonal injury to the
c hild.
A WARNING
If, in exceptional c ircumstances, you mus t
install a forwa rd-facing child restra int on
the front passenger's seat: -
Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and s ide a irbag .
- Never put the forward-facing child re­
straint up against or very near the instru­ ment panel.
- Always move the passenger seat into its
rearmost pos ition in the seat's fore a nd
aft adjustment range, as fa r away from
the airbag as possible before installing
the forwa rd-fa cing ch ild restra int. The
b ackrest mus t be ad justed to an up right
position.
- Make sure that the

Advanced Airbag System components
The front passenger seat in your vehicle has a
lot of very important parts of the Advanced
Airbag System in it. These parts include the
weight-sensing mat, sensors, wiring, brack­
ets, and more. The function of the system in
the front passenger seat is checked by the
electronic control un it when the ign it ion is on .
The control unit mon itors the Advanced Air­
bag System and turns the airbag indicator
l ight on whe n a malfunction in the system
components is de tected. The function of the
ai rbag indicator light is described in greater
detai l be low . Because the front passenger
seat contains important parts of the Ad­
vanced A irbag System, you must take care to
prevent it from be ing damaged. Damage to
the seat may prevent the Advanced Airbag for
the front passenger seat from doing its job in
a crash .
The front Advanced Airb ag System
con sis ts of the following:
- Crash sensors in the front of the veh icle that
measure veh icle acceleration/deceleration
to provide information to the Advanced Air­
bag System about the seve rity of the c rash.
- An electron ic co ntro l unit, w ith integ rated
crash sensors for fron t and side impacts.
T he contro l unit "dec ides " whether to fire
the front airbags based on the information received from the crash sensors . The contro l unit also "decides" whether the sa
fety be lt
pretensioners shou ld be activated.
- An Advanced Airbag with gas generato r and
contro l valve for the driver inside the steer­
ing wheel h ub.
- An Advanced Airbag with gas gene rator and
contro l valve inside the instrument panel for
the front passenger .
- A weight -sensing mat under the upho lstery
padding of the front passenger seat cushion
that measures the total weight on the seat.
The informat ion registered is sent continu­
ously to the electronic control unit to regu­ late deployment of the front Advanced Air­
bag on the passenger side.
- An airbag monitoring system and indicator
light in the instrument cluster~
page 161 .
-A sensor in each front seat registers the dis­
tance betwee n the respective seat a nd the
steer ing whee l o r inst rument panel. The in­
formation registered is sent cont inuous ly to
t he ele ctron ic contro l uni t to regula te de­
p loyment of the front Adva nced A irbags .
- The
PASSENGER AIR BAG OFF light comes
on and st ays on in the center of the instr u­
ment p anel
~page 162, fig. 168 and t ells
you when the front Advanced Airbag on the
passenger side has been turned off .
- A sensor below the safety be lt latch for the
front seat passenger to measure the tension
on t he safety be lt . The tension on the safety
be lt and the weight registered by the
weight-sensing mat he lp the control unit
"decide" whether the front airbag for the
front passenger seat should be turned off or not
~ page 153, Child restraints on the
front seat -some important things to
know.
- A sensor in the safety belt latch fo r the driv­
er and fo r the fro nt seat passenger that
senses whether that safety bel t is latched or
no t and transmi ts this information to t he
electronic control unit.

_& WARNING
If, in exceptional circumstances, you must
install a forward-facing child restraint on
the front passenger's seat:
- Always make sure the forward-facing
seat has been designed and certified by its manufacturer for use on a front seat
with a passenger front and side airbag.
- Always follow the manufacturer's in­
structions provided with the child safety
seat or carrier.
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible before installing
the child restraint. The backrest must be adjusted to an upright position .
- Always make sure that the
PASSENGER
AIR BAG OFF
light comes on and stays
on all the time whenever the ignition is
switched on.
(D Tips
Always replace child restraints that were
installed in a vehicle during a crash. Dam­
age to a child restraint that is not visible
could cause it to fail in another collision
situation.
Advanced front airbag system and children
Your vehicle is equipped with a front "Ad­
vanced Airbag System" in compliance with United States Federal Motor Vehicle Safety
Child Safety 175
Standard (FMVSS) 208 as applicable at the
time your vehicle was manufactured.
The Advanced Airbag system in your vehicle
has been certified to meet the "low-risk" re­
quirements for 3- and 6-year old children on
the passenger side and small adults on the driver side. The low risk deployment criteria
are intended to reduce the risk of injury
through interaction with the airbag that can
occur, for example, by being too close to the
steering wheel and instrument panel when
the airbag inflates . In addition, the system
has been certified to comply with the "sup­
pression" requirements of the Safety Stand­
ard, to turn off the front airbag for infants up
to 12 months who are restrained on the front
passenger seat in child restraints that are list­
ed in the Standard.
Even though your vehicle is equipped with an
Advanced Airbag system, all children, espe­ cially those 12 years and younger, should al­
ways ride in the back seat properly restrained
for their age and si ze. The airbag on the pas­
senger side makes the front seat a potentially dangerous place for a child to ride . The front
seat is not the safest place for a child in a for­
ward-facing child safety seat. It can be a very
dangerous place for an infant or a larger child
in a rearward-facing seat .
Advanced Airbags and the weight­
sensing mat in the front seat
The Advanced Airbag System in your vehicle
detects the presence of an infant or child in a
child restraint on the front passenger seat us­
ing the weight -sensing mat in the seat cush­
ion and the sensor below the safety belt latch
on the front passenger seat that measures the
tension on the safety belt.
The weight -sensing mat measures total
weight of the child and the child safety seat
and a child blanket on the front passenger seat. The weight on the front passenger seat
is related to the design of the child restraint
and its "footprint", the size and shape of the
bottom of the child restraint as it sits on the ..,.

178 Child Safety
&_ WARNING
Not using a child safety seat, using the
wrong child safety seat or improperly in­
stalling a child restraint increases the risk
of serious personal injury and death .
-All vehicle occupants and especially chil ­
dren must always be restrained properly
whenever riding in a vehicle.
-
- An unrestrained or improperly restrain­
ed child can be injured or killed by be­
ing thrown against the inside of the ve­
hicle or by being ejected from it during
a sudden maneuver or impact .
- An unrestrained or improperly restrain­
ed child is at much greater risk of injury
or death by being struck by an inflating
airbag.
- Commercially available child safety seats
are required to comply with U.S. Federal
Motor Vehicle Safety Standard (FMVSS)
213 (in Canada CMVSS 213).
- When buying a child restraint, select
one that fits your child and the vehicle.
- Only use child restraint systems that
fully contact the flat portion of the
seat cushion. The child restraint must not tip or lean to either side. Audi does
not recommend using child safety
seats that rest on legs or tube -like
frames . They do not provide adequate
contact with the seat.
-Always heed all legal requirements per­
taining to the installation and use of
child safety seats and carefully follow
the instructions provided by the manu­
facturer of the seat you are using.
- Never allow children under 57 inches
(1.45 meters) to wear a normal safety
belt. They must always be restrained by a
proper child restraint system. Otherwise,
they could sustain injuries to the abdo­
men and neck areas during sudden brak­
ing maneuvers or accidents.
- Never let more than one child occupy a
child safety seat . -
Never let babies or older children ride in
a vehicle while sitting on the lap of an­
other passenger .
- Holding a child in your arms is never a
substitute for a child restraint system.
- The strongest person could not hold
the child with the forces that exist in
an accident. The child will strike the in­
terior of the vehicle and can also be
struck by the passenger.
- The child and the passenger can also
injure each other in an accident.
- Never install rear-facing child safety
seats or infant carriers on the front pas­
senger seat. A child will be seriously in­
jured and can be killed when the passen­
ger airbag inflates -even with an Ad­
vanced Airbag System .
- The inflating airbag will hit the child
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the backrest, center
armrest, door or roof.
-Always install rear-facing child safety
seats or infant carriers on the rear seat .
- Forward-facing child safety seats instal­
led on the front passenger's seat can in­
terfere with the airbag when it inflates
and cause serious injury to the child. Al­
ways install forward-facing child safety
seats on the rear seat.
- If exceptional circumstances require the
use of a forward-facing child restraint on
the front passenger's seat, the child's
safety and well-being require that the
following special precautions be taken :
- Make sure the forward-facing seat has
been designed and certified by its man­
ufacturer for use on a front seat with a
passenger front and side airbag.
-Always carefully follow the manufac­
turer's instructions provided with the child safety seat or carrier.
- Always move the front passenger seat
into the rearmost position of the pas­
senger seat's fore and aft adjustment range, and as far away from the airbag

as possible before installing the child
restraint.
- Always make sure that nothing pre­
vents the front passenger's seat from
be ing moved to the rearmost position
in its fore and aft adjustment range.
- Always make sure that the backrest is
in the upr ight position.
- Always buck le the child safety seat firmly
in place even if a child is not sitting in it.
A loose ch ild safety seat can fly around
dur ing a sudden stop or in a col lision .
- Always read and heed all WARNINGS
whenever using a child restrained in ave­
hicle is being used

fig. 186. Vehicles with
two rear seating positions* are equipped with two tether anchors .
A tether is a straight orV-shaped strap that
attaches the top part of a child restraint to
special anchorage points in the vehicle.
Child Safety 191
The purpose of the tether is to reduce the for­
ward movement of the child restraint in a
crash, in order to help reduce the risk of head
injury that could be caused by striking the ve­
hicle interior .
Forward facing child restra ints manufactured
after September 1, 1999, are required by U.S.
federal regulations to comply with new child
head movement performance requirements.
These new performance requirements make a
tether necessary on most new child safety
seats .
.&_ WARNING
Improper installation of child restraints
will increase the risk of injury and death in
a crash.
- Always follow the instructions provided
by the manufacturer of the child re­
straint you intend to install in your Audi.
- Improper use of child restraint anchors
(including tether anchors) can lead to in­
jury in a collision . The anchors are de­
signed to withstand only those loads im­
posed by correctly fitted child restraints .
- Never mount two child restraint systems
on one LATCH lower anchor point.
- Never attach two child restraint systems to one tether strap or tether anchorage.
- Never attach a tether strap to a tie-down
hook in the luggage compartment.
- Never use child restraint tether ancho­
rages to secure safety belts or other
kinds of occupant restraints.
- Never secure or attach any luggage or
other items to the LATCH lower ancho­ rages or to the tether anchors .
- If a tether or other strap is used to at­
tach a child restraint to the front passen­ ger seat, make sure that it is not so
tight, that it causes the weight -sensing
mat to measure more weight than is ac­
tually on the seat .
- The heavier weight registered can make
the Advanced Airbag System work as

temperature. This determines the current
state of charge and the power of the battery.
Idling current management
Idling current management reduces energy
consumpt ion while the vehicle is stand ing.
With the ignition switched off, it contro ls the
energy supply to the various e lectrica l compo ­
nents . Data from battery diagnosis is consid­
ered.
D epending on the battery's state of charge,
individua l consumers are gradua lly turned off
to prevent excessive discharge of the battery
and thus maintain starting capability.
Dynamic energy management
While the veh icle is being driven, dynamic en­
ergy management dist ributes the energy gen­
erated according to the needs of the individu­
a l components . It reg ulates consumption, so
that more electrical energy is not being used
than is being generated and ensures an opti­
mal state of charge for the battery.
- But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are
limited.

cator light (•) appears

Battery .
What you should know
The highest priority is given to maintaining
starting capability .
The battery is severely taxed in short-distance
driving, in city traffic and during the cold time
of year. Abundant electrical energy is re­
qu ired, but only a little is generated. It is also
cr itica l if the engine is not running and electri­
cal components are turned on. In th is in­
stance energy is being consumed but none is
be ing generated .
Intelligent technology 203
It is in precisely these situations that you will
notice energy management active ly regu lat­
ing the distribution of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period
of several days or weeks, e lectrica l compo­
nents are gradually cut back or switched off.
This reduces energy consumption and main­
tains starting 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
functions will be available again when you
switch on the ignition and start the eng ine.
With the engine turned off
If you listen to the radio, for example, with
the engine turned off or use other MMI func­
tions, the battery is being discharged.
If starting capability is jeopardi zed due to en­
ergy consumption , the following warning ap­
pears in the MM I 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 w ish to continue using the functions, you
have to start the engine.
With the engine running
Although electrical energy is generated when
the vehicle is being driven, the battery can be­
come discharged . This happens mostly when
li ttle energy is being generated and a great
deal consumed and the battery's state of
charge is not optimal.
T o b ring the energy ba lance back into equili­
brium , consumers wh ich requ ire espe cially
large amounts of energy are temporarily cut
back or switched off . Heating systems in par­
ticular require a great deal of energy. If you
notice, for examp le, that the heated seats* or
the heated rear window are not heating, they
have been temporarily cut back or switched .,.
