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 dr iver's seat and steering wheel
properly ¢
page 161,
"" Adjust the front passenger's seat properly
¢page 72 ,
"" Wear safety be lts properly ¢
page 173,
"" Always properly use the proper child re-
straint to protect chi ldren ¢
page 200.
In a collision, airbags must inflate within the blink of an eye and with considerable force .
The supplemental airbags can cause injuries if
the driver 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
driver and as a passenge r to s it properly at all
times.
By keeping room between your body and the
steer ing wheel and the front of the passenger
compartment, the airbag can inflate fully and
comp letely 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 individual
safety features installed in your Aud i work to
gether as a system.
Proper seat ing pos ition is important so that
the front airbag on the driver s ide can do its
job. If yo u have a physical impa irment or con-
A irbag system 179
dition that prevents yo u from sitting properly
on 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 workshop, or call Audi Customer Re
l ations at 1-800-822-2834 for poss ible modi
ficat io ns to your veh icle.
When the airbag system dep loys, a gas gener
ator will fill the a irbags, break open the pad
ded covers, and inflate between the steer ing
whee l and the dr iver and between the instru
ment pane l and the front passenger. The a ir
bags will deflate immediately after dep loy
ment so that the front occupants can see
through the windshield again 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 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 airbags in combination with properly
worn safety belts slow down and lim it the oc
cupant's forward movement . T ogether they
help to prevent the driver and front seat pas
senger from h itti ng pa rts of the inside of the
vehicle while reducing the forces acting on the
occupant during 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 will not inflate in all fronta l
collisions . The triggering of the airbag system
depends on the vehicle de ce leration rate
caused by the collision and regis te red by the
electron ic control unit. If th is rate is below
the reference value programmed into the con
trol unit, the airbags will not be trigge red ,
even though 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 veh icle damage
is not necessarily an indication of whether an
airbag should inflate or not . .,. •

-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 an "Advanced
Airbag System" in compliance with United
States Federal Motor Vehicle Safety Standard
Child Safety 201
(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 ..,.

can result in there being insufficient energy
avai lab le to start the engine .
I ntell igent energy management in your vehi
cle handles the distribution of electrical ener
gy . Starting abi lity is markedly improved and
the life of the battery is extended .
Basically , energy management consists of
battery diagnosis , idling current manage
ment
and dynamic energy management.
Battery diagnosis
Battery diagnosis continuously determines
the state of the battery. Sensors determine
battery volta ge, battery current and battery
temperature. This determines the current
state of charge and the power of the battery.
Idling current management
Idling current management reduces energy
consumption 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.
Depending on the battery's state of charge,
individua l consumers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability.
Dynamic energy management
While the vehicle is being dr iven , dynamic en
e rg y management distributes the energy gen
erated according to the needs of the individu
a l components. It regulates consumption, so
that more ele ctrical energy is not being used
than is being generated and ensures an opti mal state of cha rge 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 starting ab ility is threatened, you are
i nformed by a warn ing
c> page 22 7,
Driver notification in the instrument
cluster display .
What you should know
The highest priority is given to maintaining
starting capability .
The battery is seve rely taxed in shor t-distance
driving, in city tra ffic and dur ing 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 e lectri
ca l components are turned on . In this in
stance energy is being consumed but none is
being generated.
It i s in precisely these situations that you will
notice energy management actively regulat
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 lectr ica l compo
nents are gradually cut back or sw itched off.
T his reduces energy consumption and main
ta ins start ing capability over a longer period .
Take into consideration that when you unlock
your vehicle , some conven ience functions ,
s uc h as the inte rior lights or the power seat
adjustment, may not be available. The con
venience functions will be available again
when you turn on the ignition and start the e ngine .
With the engine turned off
If you listen to the radio, for example, w ith
the engine turned off or use other MMI func
tions, the battery is being discharged .
If starting capability is jeopardized due to en
ergy consumption , the following warning ap
pears in the MMI display:
Please start engine, otherwise system will
switch off in 3 minutes .
The warning indicates that the system will be
turned off automatically after 3 minutes . If
you w ish to continue using the funct ions, you
have to sta rt the eng ine.

should only be disconnected from the vehicle
e lectrical system when absolutely necessary
for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a pe riod
of several days or weeks, electrical compo
nents are gradually cut back or switched off.
This reduces energy consumption and main
tains starting capab ility over a longer period
c;, page225.
Take into consideration that when you un lock
your vehicle, some convenience functions, such as the interior lights or the power seat
adjustment, may not be available. The con
venience functions will be available again
when you turn on the ignition and start the
engine .
Winter operation
During the winter months, battery capacity
tends to decrease as temperatures drop . This
is because more power is also consumed while
starting, and the headlights, rear window de
fogger, etc., are used more often .
Avoid unnecessary power consumption, par
ticularly in city traffic or when traveling only
short d istances . Let your authorized Audi
dealer check the capacity of the vehicle bat
tery before w inte r sets in
¢ page 271. A well
cha rged battery w ill not only prevent starting
p rob lems when the weather is cold, but will
a lso last longer.
(D Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the
vehicle battery should be removed and
stored where it will not freeze . This wi ll
prevent it from being damaged and having
to be replaced.
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located under the driver 's seat.
Before you check anyth ing under the driver 's
seat,
read and heed all WARNINGS c:;, _&.
Always heed the safety warnings, when work
ing on the vehicle battery or the vehicle elec
trical system to prevent injury.
The following WARNINGS are very
important when working on the battery:
