Airbag system
Important things to know
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints. For airbags to
do their jo b, occu pants must always properly we ar their
safety belts and be in a proper seating position.
Fo r your safe ty a nd the safety o f your passen gers, before
dr iving o ff, a lways:
- Adjust the driver 's seat and steering wheel proper ly
=> page 200,
- Adjust the front passenger's seat properly=> page 87,
-Wear safety be lts proper ly=> page 212,
- Always properly use the proper chi ld restrain t to pro tect
ch ildren
=> page 243 .
In a collision airbags mus t inflate with in t he blink of an eye and with
considerable force . The supplemental airbags can cause injuries if
t he driver or the fron t seat passenger is not seated properly. There ­
fore in order to help the airbag to do its job, it is important, both as a driver and as a passenger to sit properly at a ll ti mes.
By keep ing room between your body and t he steer ing wheel and the
front of the passenger compartment, the airbag can inflate fu lly and
comp letely and prov ide supplementa l protection in certain frontal
collisions => page 200, "Proper occupant seating positions". For
deta ils on the operation of t he seat adjustment
controls => page 87.
It's especia lly important that chi ldren are proper ly restrained
=> page 243 .
There is a lot that the driver and the passengers can and must do to
help the individual safety features installed in your Audi work
together as a system.
P roper seating position is important so that the front airbag on the
driver side ca n do its job. I f yo u have a physical impairment or
condition that prevents you from sitting properly on the driver seat
wi th the safety belt p roperly fastened and reaching the pedals, o r if
you have concerns with regard to the function or operation of the
Advanced Airbag System, p lease contact your authorized Audi
dea ler or qua lif ied workshop, or call Audi Customer CAR E at 1 -800-
822 -2834 for possib le modifications to your vehicle .
When the a irbag system deploys, a gas generator wi ll fil l the
airbags, break open the padded covers, and inflate between the
steer ing wheel and the dr iver and between the inst rume nt panel
and the front passenger. The airbags wi ll deflate immediate ly after
deployment so that the front occupants can see through the wind ­
shield again without interruption .
A ll of this takes p lace in the b link of an eye, so fast that many people
do n't even rea lize that the a irbags have dep loyed . T he airbags also
inflate with a great dea l of force and nothing should be in their way
when they dep loy. Fron t airbags in combinati on wi th properly worn
safety belts slow down and limit the occupant's forward movement.
Together t hey help to prevent the driver and front seat passenger
from hitting parts of the inside the vehicle while reducing the forces act ing on the occupant during the crash . In this way they he lp to
reduce the r isk 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 a irbags w ill not in flate i n all fro ntal col lis io ns. The trig­
gering of the airbag system depends on the vehic le dece lerat ion
r ate caused by the co llision and registe red by the electr onic c ontro l
unit . If this rate is be low the reference value programmed into the
co ntrol unit, the ai rbags w il l not be t riggered, even tho ug h the car
may be bad ly damaged as a result of the collision . Vehicle damage,

& WARNING (continued)
• If you must install a rearward facing child seat on the front
passenger seat because of exceptional circumstances and the
PASSENGER AIR BAG OFF light does not come on and stay on,
immediately install the rear-facing child seat in a rear seating posi­
tion and have the airbag system inspected 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.
• Never put the forward-facing child restraint up against or very
near the instrument panel.
• 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 forward-facing child
restraint. The backrest must be adjusted to an upright position.
• Make sure that the PASSENGER AIR BAG OFF light comes on
and stays on all the time whenever the ignition is switched on. •
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, brackets, and more. The func ­
tion of the system in the front passenger seat is checked by the elec­
tronic control unit when the ignition is on. The control unit monitors
the Advanced Airbag System and turns the airbag indicator light on
when a malfunction in the system components is detected. The
function of the airbag indicator light is described in greater detail below . Because the front passenger seat contains important parts
Controls and equip­
ment Safety first Vehicle operation
of the Advanced Airbag System, you must
take care to prevent it
from being 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 Airbag System consists of the
following:
• Crash sensors in the front of the vehicle that measure vehicle
acceleration/deceleration to provide information to the Advanced
Airbag System about the severity of the crash.
• An electronic control unit, with integrated crash sensors for front
and side impacts. The control unit "decides" whether to fire the
front airbags based on the information received from the crash
sensors. The control unit also "decides" whether the safety belt
pretensioners should be activated.
• An Advanced Airbag with gas generator for the driver inside the
steering wheel hub.
• An Advanced Airbag with gas generator inside the instrument
panel for the front passenger.
• A weight -sensing mat under the upholstery padding of the front
passenger seat cushion that measures the total weight on the seat.
The information registered is sent continuously to the electronic
control unit to regulate deployment of the front Advanced Airbag on
the passenger side .
• An airbag monitoring system and indicator light in the instru­
ment
cluster => page 229.
• The PASSENGER AIR BAG OFF light comes on and stays on in the
center of the instrument
panel => page 230, fig. 233 and tells you
when the front Advanced Airbag on the passenger side has been
turned off .
• A sensor below the safety belt latch for the front seat passenger
to measure the tension on the safety belt . The tension on the safety
belt and the weight registered by the weight-sensing mat help the
control unit
"decide" whether the front airbag for the front
passenger seat should be turned off or
not=> page 220, "Child
restraints on the front seat
-some important things to know". .,_

vidual components . It regulates consumption, so that more elec­
t rical energy is not be ing used than is be ing genera ted and ensures
an optimal state of charge for the battery .
[ i ] Tip s
• But even energy management cannot 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
~ page 275, "Driver notification in the instrument cluster
display" .•
What you should know
The highest priority is given to maintaining starting capa ­
bility.
T he battery is severely taxed in short -distance driving, in city traffic
and during t he co ld time of year . Abundant e lectrica l energy is
required, but on ly a little is generated . It is also critical if the engine
is not running and e lectrical components are turned on. In this
instance energy is being consumed but none is being generated .
I t is in precisely these situations that you wi ll notice energy manage ­
ment active ly regulating the d istr ibut ion of energy.
Vehicl e stands for an extended period
If you do not drive your vehicle over a per iod of several days or
weeks, electrica l components are gradually cut back or switched off.
This reduces energy consu mpt ion and maintains starting capability
over a longer period .
Be aware t hat when you unlock you r ve hicle, some o f the conve ­
nience functions may not operate, such as the Advanced Key, the
remote contro l or t he power seat adjustment. T he convenience
functions will be available again when you turn on the ignition and start the engine .
Controls and equip­
ment Safety first Vehicle operation With th
e engin e turned off
If you listen to the radio, for examp le, with t he engine tu rned off or
use other MMI functions, the battery is being discharged.
I f starting capabi lity is jeopardized due to energy consumption, the
f o llow ing warn ing appears in t he MMI display:
Ple ase start engine , other wise sy stem will s witch off in 3
minute s.
The warning indicates that the system wi ll be turned off au tomat i­
ca lly after 3 minutes. If you wish to continue using the functions,
you have to start the engine .
With the engine running
Although e lectrica l energy is generated when the vehic le is being
driven, the battery can become discharged. This happens mostly
when little energy is being generated and a great deal co nsumed
and the battery's state of charge is not optimal.
To br ing the ene rgy balance bac k into equi librium , cons umers
which require especially large amounts of energy are temporar ily
cu t back or switched off . Heating systems in part icu lar require a
great deal of energy. If you notice, for example, that the heated
seats* o r the heated rear w indow are not heating, they have been
temporari ly cut back or switc hed off. These systems wil l be avai lable
again as soon as the energy balance has been restored.
You wil l also notice t hat engi ne idle speed has been increase d
s lightly . This is norma l and not a cause for concern . By increasing
engine idle speed the addi tiona l energy required is ge nerated a nd
the battery is charged. •
