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.
For your safety and the safety of your passen
gers, before driving off, always:
"" Adjust the driver's seat and steering wheel
properly ¢
page 140,
"" Adjust the front passenger's seat properly
¢page 62 ,
""Wear safety be lts properly r::::> page 152,
"" Always properly use the proper child re-
straint to protect chi ldren
r::::> page 178.
In a collision airbags must inflate within th e
blink of an eye and with considerable force.
The supplemental airb ags can cause injuries if
the driver or the front seat passenger is not
seated properly . Th erefore in order to help the
a ir bag to do its job, it is important, both as a
driver and as a passenge r to s it properly at all
times.
By keeping room between your body and the
steer ing whee l and the front of the passenger
compartment, the airbag can inflate fully and
comp lete ly and provide supplemental protec
tion in certain frontal collisions

There is a lot that the driver and the passen
gers can and must do to help the individua l
safety features installed in your Aud i work to
gether as a system.
Proper seating pos ition is important so that
the front airbag on the driver side can do its
job. If you have a physical impairment or con-
Airbag system 157
dition that prevents you from sitting properly
on the driver seat with the safety belt properly
fastened and reaching the pedals, spec ial
modifications to yo ur vehicle may be necessa
ry.
Contact your authorized Audi dea ler, or call
Audi Customer Re lations at 1-800-822-2834.
When the airbag system dep loys, a gas gener
ator will fi ll the airbags, break open the pad
ded covers, and inf late between the steering
whee l and the driver and between the instru
ment panel and the front passenger. The air
bags will deflate immediately after deploy
ment so that the front occupants can see
through the windshield aga in without inter
ruption .
All of th is takes place in the blink of an eye, so
fast that many people don't even realize that
the air bags have deployed . The airbags also
inflate with a great deal of force and noth ing
shou ld be in their way when they deploy.
Front airbags in combination with properly
worn safety belts slow down and limit the oc
cupant's forward movement. Together they
help to prevent the driver and front seat pas
senge r from hitting parts of the inside the ve
hicle while reducing the forces acting on the
occupant dur ing the crash. In this way they
help to reduce t he risk of injury to the head
and upper body in the crash . A irbags do not
protect the arms or the lower parts of the
body .
Both front air bags w ill not inflate in all frontal
collisions . The triggering of the airbag system
depends on the vehicle deceleration rate
caused by the collision and registered by the
electron ic control unit. If this rate is below
the reference value programmed into the con
trol unit, the airbags will not be triggered,
ev en though the car may be bad ly damaged as
a resu lt of the co llision . Vehicle damage, re
pair costs or even the lack of ve hicle damage
is no t necessarily an indication of whether an
airbag should inflate o r not .
It is not possib le to define a range of vehicle
speeds that w ill cover every possible kind and ..,.

Advanced Airbag System components
The fron t passenger sea t in your vehicle h as a
lot of very important par ts of the Advanced
Airbag System in it. These parts include t he
weight -sensing mat, sensors, wiring, brack
ets, and more. The function of the system in
the front passenger seat is checked by the
e lectronic control un it when the ignit ion is on.
The control unit mon itors the Advanced Air
bag System and turns the airbag indicator
l ight on when a ma lfunction in t he system
components is detected. The func tion of the
a ir bag ind icator 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 m ust 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 Sy stem
consists 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 abou t the seve rity of the crash.
- An electron ic co ntrol unit, with integ rated
crash sensors for front and side impacts .
T he cont ro l unit "dec ides " w het her to fire

A WARNING
Damage to the front passenger seat can
p revent the front airbag from work ing
properly.
-
-Always install rear-facing child safety
seats on the rear seat.
- If you must install a rearward facing
child safety seat on the front passenger
seat in exceptional circumstances and
the
PASSENGER AIR BAG OFF light does
not come on and stay on, immediately
install the rear-facing child safety seat in
a rear seating position and have the air
bag system inspected immediately by
your Audi dealer.
_& 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 1 79
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 size. 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 ..,.

182 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

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 cu rrent consumers
(e.g. immobilizer). In ce rtain c ircumstances it
can result in there being insuff icient ene rgy
avai lab le to s tart the engine .
I ntelligent energy management in your vehi
cle hand les the d ist ribution of electrical ener
gy. Starting ab ility is marked ly imp roved and
the life of the battery is extended.
Basically , energy management consists of
b atter y dia gno sis, idling curr ent manag e
m ent
and dynami c en ergy m anag emen t.
Battery diagnosis
Battery d iagnosis continuously determ ines
the state of the battery . Sensors determ ine
battery vo ltage, battery curren t and battery
temperature. This dete rm ines the current
state of charge and the power of the battery .
Idling current management
Idling current management reduces energy
consumpt ion wh ile the veh icle is stand ing .
W ith the ignition switched off, it cont ro ls the
energy s upply to the va rio us electr ical compo
nents. Data from battery diagnosis is consid
ered.
D epending on the batte ry's state of charge,
i nd ividual consumers are grad ua lly turned off
to p revent excessive discharge of the battery
and thus maintain starting capability .
Dynamic energy management
W hil e the vehicle is being driven, dynamic en
e rgy management dist ributes t he energy gen-
Int ellig ent technolog y 203
erated according to the needs of the individ u
al components. It regulates 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.
(D Tips
- But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are
limited.
- If start ing ability is t hreatened, the indi
cator light(•] appears¢
page 34 .
What you should know
The highest priority is given to maintaining
star ting capability.
The battery is severe ly taxed in short-distance
driving, in city traff ic and during the cold time
of year. Abundant elect rical energy is re
quired, but only a lit tle is generated . It is also
crit ical if the engine is not running and electri
cal components are turned on. In this in
stance ene rgy is be ing consumed but none is
being genera ted .
It is in precisely these situations that you will
not ice energy management actively regulat
ing the d istribution of ene rgy.
Vehicle stand s for an e xtended period
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 pe riod .
Some of the convenience func tions may not
opera te , such as the interior ligh ts or the
power seat adjustment. The convenience
funct ions w ill be available again when you
switch on the ignition and start the engine.
With the en gine turn ed off
If you listen to the radio, for exam ple, w ith
the engine turned off or use other MMI* func-
tions, the battery is being discharged .
