Safe driving

> Never allow anyone to assume an incorrect
seating position when the vehicle is being used
>/\.
The following bulletins list only some sample po-
sitions that will increase the risk of serious injury
and death. Our hope is that these examples will
make you more aware of seating positions that
are dangerous.
Therefore, whenever the vehicle is moving:
— never stand up in the vehicle
— never stand on the seats
— never kneel on the seats
— never ride with the seatback reclined
— never lie down on the seats
— never lean up against the instrument panel
— never sit on the edge of the seat
— never sit sideways
— never lean out the window
— never put your feet out the window
— never put your feet on the instrument panel
— never rest your feet on the seat cushion or back
of the seat
— never ride in the footwell
— never ride in the cargo area

ZA\ WARNING
Improper seating positions increase the risk
of serious personal injury and death whenever
a vehicle is being used.
— Always make sure that all vehicle occupants
stay in a proper seating position and are
properly restrained whenever the vehicle is
being used.

ZA\ WARNING
Always make sure that the knee airbag can in-
flate without interference. Objects between
yourself and the airbag can increase the risk
of injury in an accident by interfering with the



180

way the airbag deploys or by being pushed in-
to you as the airbag deploys.
— No persons (children) or animals should ride
in the footwell in front of the passenger
seat. If the airbag deploys, this can result in
serious or fatal injuries.
— No objects of any kind should be carried in
the footwell area in front of the driver's or
passenger's seat. Bulky objects (shopping
bags, for example) can hamper or prevent
proper deployment of the airbag. Small ob-
jects can be thrown through the vehicle if
the airbag deploys and injure you or your
passengers.

Pedal area
The pedals must always be free to move and
must never be interfered with by a floor mat or
any other object.
Make sure that all pedals move freely without in-
terference and that nothing prevents them from
returning to their original positions.
Only use floor mats that leave the pedal area free
and can be secured with floor mat fasteners.
If a brake circuit fails, increased brake pedal trav-
el is required to bring the vehicle to a full stop.

ZA\ WARNING
Pedals that cannot move freely can cause loss
of vehicle control and increase the risk of seri-
ous injury.
— Never place any objects in the driver's foot-
well. An object could get into the pedal area
and interfere with pedal function. In case of
sudden braking or an accident, you would
not be able to brake or accelerate!
— Always make sure that nothing can fall or
move into the driver's footwell.

Safety belts

Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for peo-
ple riding in vehicles.

BFV-0184





BFV-0185



(2,000 lbs, or 1,000 kg) or more. At higher
speeds, these forces are even greater.
People who do not use safety belts are also not
attached to their vehicle. In a frontal collision
they will also keep moving forward at the speed
their vehicle was travelling just before the crash.
Of course, the laws of physics don't just apply to
frontal collisions, they determine what happens
in all kinds of accidents and collisions.
What happens to occupants not wearing
liam llieya
In crashes unbelted occupants cannot stop
themselves from flying forward and being in-
jured or killed. Always wear your safety belts!

Fig. 148 The vehicle crashes into the wall
The physical principles are simple. Both the vehi-
cle and the passengers possess energy which var-
ies with vehicle speed and body weight. Engi-
neers call this energy “kinetic energy.”
The higher the speed of the vehicle and the
greater the vehicle's weight, the more energy
that has to be “absorbed” in the crash.
Vehicle speed is the most significant factor. If the
speed doubles from 15 to 30 mph (25 to 50
km/h), the energy increases 4 times!
Because the passengers of this vehicle are not us-
ing
safety belts > fig. 147, they will keep moving
at the same speed the vehicle was moving just
before the crash, until something stops them -
here, the wall > fig. 148.
The same principles apply to people sitting in a
vehicle that is involved in a frontal collision. Even
at city speeds of 20 to 30 mph (30 to 50 km/h),
the forces acting on the body can reach one ton

Fig. 149 A driver not wearing a safety belt is violently
thrown forward
Unbelted occupants are not able to resist the tre-
mendous forces of impact by holding tight or
bracing themselves. Without the benefit of safe-
ty restraint systems, the unrestrained occupant
will slam violently into the steering wheel, in-
strument panel, windshield, or whatever else is
in the way > fig. 149. This impact with the vehi-
cle interior has all the energy they had just before
the crash.
Never rely on airbags alone for protection. Even
when they deploy, airbags provide only additional
protection. Airbags are not supposed to deploy in
all kinds of accidents. Although your Audi is
equipped with airbags, all vehicle occupants, in-
cluding the driver, must wear safety belts cor-
rectly in order to minimize the risk of severe in-
jury or death in a crash.
Remember too, that airbags will deploy only once
and that your safety belts are always there to
183

>

Safety belts

offer protection in those accidents in which air-
bags are not supposed to deploy or when they
have already deployed. Unbelted occupants can
also be thrown out of the vehicle where even
more severe or fatal injuries can occur.
Safety belts protect
People think it's possible to use the hands to
brace the body ina minor collision. It's simply
not true!

maneuver.
Safety belts used properly can make a big differ-
ence. Safety belts help to keep passengers in
their seats, gradually reduce energy levels ap-
plied to the body in an accident, and help prevent
the uncontrolled movement that can cause seri-
ous injuries. In addition, safety belts reduce the
danger of being thrown out of the vehicle.
Safety belts attach passengers to the car and give
them the benefit of being slowed down more
gently or “softly” through the “give” in the safety
belts, crush zones and other safety features engi-
neered into today's vehicles. By “absorbing” the
kinetic energy over a Longer period of time, the
safety belts make the forces on the body more
“tolerable” and less likely to cause injury.
Although these examples are based on a frontal
collision, safety belts can also substantially re-
duce the risk of injury in other kinds of crashes.
So, whether you're on a long trip or just going to
the corner store, always buckle up and make sure
others do, too. Accident statistics show that vehi-
cle occupants properly wearing safety belts have
a lower risk of being injured and a much better
chance of surviving an accident. Properly using
184

safety belts also greatly increases the ability of
the supplemental airbags to do their job in a col-
lision. For this reason, wearing a safety belt is le-
gally required in most countries including much
of the United States and Canada.
Although your Audi is equipped with airbags, you
still have to wear the safety belts provided. Front
airbags, for example, are activated only in some
frontal collisions. The front airbags are not acti-
vated in all frontal collisions, in side and rear col-
lisions, in rollovers or in cases where there is not
enough deceleration through impact to the front
of the vehicle. The same goes for the other airbag
systems in your Audi. So, always wear your safety
belt and make sure everybody in your vehicle is
properly restrained!

Safety belts must always be correctly positioned
across the strongest bones of your body.
> Always wear safety belts as illustrated and de-
scribed in this chapter.
> Make sure that your safety belts are always
ready for use and are not damaged.

ZA WARNING
Not wearing safety belts or wearing them im-
properly increases the risk of serious personal
injury and death. Safety belts can work only
when used correctly.
— Always fasten your safety belts correctly be-
fore driving off and make sure all passen-
gers are correctly restrained.
— For maximum protection, safety belts must
always be positioned properly on the body.
— Never strap more than one person, including
small children, into any belt.
— Never place a safety belt over a child sitting
on your lap.
— Always keep feet in the footwell in front of
the seat while the vehicle is being driven.
— Never let any person ride with their feet on
the instrument panel or sticking out the
window or on the seat.

ZA WARNING
Never unfasten safety belt while the vehicle is
moving. Doing so will increase your risk of be-
ing injured or killed.
Improperly worn safety belts
Incorrectly positioned safety belts can cause se-
vere injuries.


Wearing safety belts improperly can cause seri-
ous injury or death. Safety belts can only work
when they are correctly positioned on the body.
Improper seating positions reduce the effective-
ness of safety belts and will even increase the risk
of injury and death by moving the safety belt to
critical areas of the body. Improper seating posi-
tions also increase the risk of serious injury and
death when an airbag deploys and strikes an oc-
cupant who is not in the correct seating position.
A driver is responsible for the safety of all vehicle
occupants and especially for children. Therefore:
> Never permit anyone to assume an incorrect sit-
ting position in the vehicle while traveling
>.
ZA WARNING
Improperly worn safety belts increase the risk
of serious personal injury and death whenever
a vehicle is being used.
— Always make sure that all vehicle occupants
are correctly restrained and stay in a correct
seating position whenever the vehicle is be-
ing used.
— Always read and heed all WARNINGS and
other important information > page 184.



Safety belt tensioner
How safety belt pretensioners work
Pyrotechnic safety belt pretensioners
Seat belts with pyrotechnic safety belt preten-
sioners are tensioned automatically in severe col-
lisions, depending on the circumstances. This
helps to reduce the forward motion of the occu-
pants.

Z\ WARNING
—It is possible for the pretensioners to deploy
incorrectly.
— Any work on the tensioner system or remov-
al and installation of system components
for other repairs must be performed by a
qualified workshop.
— The pyrotechnic system can only provide
protection for one collision. If the pyrotech-
nic pretensioners deploy, the pretensioning
system must be replaced. >

sitting properly
Airbags are only supplemental restraints. For
airbags to do their job, occupants must always
properly wear their safety belts and be in a prop-
er 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 178,
> Adjust the front passenger's seat properly
=> page 179,
> Wear safety belts properly > page 184,
> Always properly use the proper child restraint
to protect children > page 210.
In a collision airbags must inflate within the blink
of an eye and with considerable force. The sup-
plemental airbags can cause injuries if the driver
or the front seat passenger is not seated proper-
ly. Therefore in order to help the airbag to do its
job, it is important, both as a driver and as a pas-
senger to sit properly at all times.
By keeping room between your body and the
steering wheel and the front of the passenger
compartment, the airbag can inflate fully and
completely and provide supplemental protection
in certain frontal collisions > page 178, Correct
passenger seating positions. For details on the
operation of the seat adjustment controls
=> page 46.
It's especially important that children are proper-
ly restrained > page 210.
There is a lot that the driver and the passenger
can and must do to help the individual safety fea-
tures installed in your Audi work together as a
system.
Proper seating position is important so that the
front airbag on the driver side can do its job. If
you have a physical impairment or condition that
prevents you from sitting properly on the driver
seat with the safety belt properly fastened and
reaching the pedals, or if you have concerns with
regard to the function or operation of the Ad-
vanced Airbag System, please contact your au-
thorized Audi dealer or qualified workshop, or
call Audi Customer Relations at 1-800-822-2834
for possible modifications to your vehicle.
When the airbag system deploys, a gas generator
will fill the airbags, break open the padded cov-
ers, and inflate between the steering wheel and
the driver and between the instrument panel and
the front passenger. The airbags will deflate im-
mediately after deployment so that the front oc-
cupants can see through the windshield again
without interruption.
All of this takes place in the blink of an eye, so
fast that many people don't even realize that the
airbags have deployed. The airbags also inflate
with a great deal of force and nothing should be
in their way when they deploy. Front airbags in
combination with properly worn safety belts slow
down and limit the occupant's forward move-
ment. Together they help to prevent the driver
and passenger from hitting parts of the inside
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 frontal
collisions. The triggering of the airbag system de-
pends on the vehicle deceleration rate caused by
the collision and registered by the electronic con-
trol unit. If this rate is below the reference value
programmed into the control unit, the airbags
will not be triggered, even though the car may be
badly damaged as a result of the collision. Vehi-
cle damage, repair costs or even the lack of vehi-
cle damage is not necessarily an indication of
whether an airbag should inflate or not.
Since the circumstances will vary considerably
between one collision and another, it is not possi-
ble to define a range of vehicle speeds that will
cover every possible kind and angle of impact
that will always trigger the airbags. Important
factors include, for example, the nature (hard or
soft) of the object which the car hits, the angle of
impact, vehicle speed, etc. The front airbags will >

Airbag system

also not inflate in side or rear collisions, or in roll-
overs.
Always remember: Airbags will deploy only once,
and only in certain kinds of collisions. Your safety
belts are always there to offer protection in those
situations in which airbags are not supposed to
deploy, or when they have already deployed; for
example, when your vehicle strikes or is struck by
another vehicle after the first collision.
This is just one of the reasons why an airbag is a
supplementary restraint and is not a substitute
for a safety belt. The airbag system works most
effectively when used with the safety belts.
Therefore, always properly wear your safety belts
=> page 182.

— Always sit upright with your back against
the backrest of your seat.
— Never place your feet on the instrument
panel or on the seat. Always keep both feet
on the floor in front of the seat to help pre-
vent serious injuries to the legs and hips if
the airbag inflates.


ZA WARNING
Sitting too close to the steering wheel or in-
strument panel will decrease the effective-
ness of the airbags and will increase the risk
of personal injury in a collision.
— Never sit closer than 10 in (25 cm) to the
steering wheel or instrument panel.
— If you cannot sit more than 10 in (25 cm)
from the steering wheel, investigate wheth-
er adaptive equipment may be available to
held you reach the pedals and increase your
seating distance from the steering wheel.
— If you are unrestrained, leaning forward, sit-
ting sideways or out of position in any way,
your risk of injury is much higher.
— You will also receive serious injuries and
could even be killed if you are up against the
airbag or too close to it when it inflates -
even with an Advanced Airbag.
— To reduce the risk of injury when an airbag
inflates, always wear safety belts properly
=> page 185, Safety belts.
— If children are not properly restrained, they
may be severely injured or killed when an
airbag inflates.
— Never let children ride unrestrained or im-
properly restrained in the vehicle. Adjust the
front seats properly.
— Always sit as far as possible from the steer-
ing wheel or the instrument panel
=>page 178.
ZA WARNING
Airbags that have deployed in a crash must be
replaced.
— Use only original equipment airbags ap-
proved by Audi and installed by a trained
technician who has the necessary tools and
diagnostic equipment to properly replace
any airbag in your vehicle and assure system
effectiveness ina crash.
— Never permit salvaged or recycled airbags to
be installed in your vehicle.

Child restraints on the front seat - some
important things to know

> Be sure to read the important information and
head the WARNINGS for important details
about children and Advanced Airbags
=> page 210.
The airbag on the passenger 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 forward-facing child safety seat. It can
be a very dangerous place for an infant or a child
in a rearward-facing seat.
The Advanced Airbag System in your vehicle has
been certified to comply with the requirements
of United States Federal Motor Vehicle Safety
Standard (FMVSS) 208, as well as Canada Motor
Vehicle Safety Standard (CMVSS) 208 as applica-
ble at the time your vehicle was manufactured.
According to requirements, the front Advanced
Airbag System on the passenger side has been
certified for “suppression” for infants of about
12 month old and younger and for “low risk de-
ployment” for children aged 3 to 6 years old (as
defined in the standard).

8S8012721BA
Airbag system

The PASSENGER AIR BAG OFF %; light in the
headliner tells you when the front Advanced Air-
bag on the passenger side has been turned off by
the electronic control unit.
Each time you turn on the ignition, the PASSEN-
GER AIR BAG OFF #¥; ON ® light will come on
for a few seconds and:
— PASSENGER AIR BAG OFF #¥; will come on if
the front passenger seat is not occupied,
— PASSENGER AIR BAG OFF 3; will come on if
the electrical capacitance measured by the ca-
pacitive passenger detection system for the
front passenger seat equals the combined ca-
pacitance of an infant up to about one year of
age and one of the rearward-facing or forward-
facing child restraints listed in Federal Motor
Vehicle Safety Standard 208 with which the Ad-
vanced Airbag System in your vehicle was certi-
fied. For a listing of the child restraints that
were used to certify your vehicle's compliance
with the U.S. Safety Standard = page 212.
— PASSENGER AIR BAG OFF 3; will come on if
there is a small child or child restraint on the
front passenger seat,
— PASSENGER AIR BAG ON @ will go off if the
front passenger seat is occupied by an adult as
registered by the capacitive passenger detec-
tion system > page 200, Monitoring the Ad-
vanced Airbag System.
The PASSENGER AIR BAG OFF 3%; light comes on
when electrical capacitance registered on the
front passenger seat is equal to or less than the
combined capacitance of a typical 1 year-old in-
fant and one of the rearward-facing or forward-
facing child restraints listed in Federal Motor Ve-
hicle Safety Standard 208 with which the Ad-
vanced Airbag System in your vehicle was certi-
fied.
If the total electrical capacitance registered on
the front passenger seat is more than that of a
typical 1 year-old child but less than the weight
of a small adult, the front airbag on the passen-
ger side can deploy (the PASSENGER AIR BAG
OFF 3%; light does not come on).
If the PASSENGER AIR BAG OFF %; light does
not come on, the front airbag on the passenger
side has not been turned off by the electronic
control unit and can deploy if the control unit
senses an impact that meets the conditions stor-
ed in its memory.
For example, the airbag may deploy if:
—asmall child that is heavier than a typical 1
year-old child is on the front passenger seat (re-
gardless of whether the child is in one of the
child safety seats listed > page 212), or
—a child who has outgrown child restraints is on
the front passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF #; light comes on in
the headliner and stays on.
If the front passenger airbag deploys, the Federal
Standard requires the airbag to meet the “low
risk” deployment criteria to reduce the risk of in-
jury through interaction with the airbag. “Low
risk” deployment occurs in those crashes that
take place at lower decelerations as defined in
the electronic control unit > page 200, PASSEN-
GER AIR BAG OFF $; ON ® light.
Always remember, a child seat or infant carrier
installed on the front seat may be struck and
knocked out of position by the rapidly inflating
passenger's airbag in a frontal collision. The air-
bag could greatly reduce the effectiveness of the
child restraint and even seriously injure the child
during inflation.

A WARNING
A child in a rearward-facing child seat instal-
led on the front passenger seat will be seri-
ously injured and can be killed if the front air-
bag inflates - even with an Advanced Airbag
System.
— The inflating airbag will hit the child seat or
infant carrier with great force and will
smash the child seat and child against the
backrest, center armrest, door or roof.
— Forward-facing child seats installed on the
front passenger's seat may interfere with
the deployment of the airbag and cause seri-
ous personal injury to the child.

191

Airbag system


ZA WARNING
If, in exceptional circumstances, you must in-
stall 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 manu-
facturer for use on a front seat with a pas-
senger front and side airbag.
— Never put the forward-facing child restraint
up against or very near the instrument pan-
el.
— Always move the front passenger seat to the
highest position in the up and down adjust-
ment range and move it back to the rear-
most position in the seat's fore and aft ad-
justment range, as far away from the airbag
as possible, before installing the forward-
facing child restraint.
— Always make sure that the safety belt upper
anchorage is behind the child restraint and
not next to or in front of the child restraint
so that the safety belt will be properly posi-
tioned.
— Make sure that the PASSENGER AIR BAG
OFF 7; light comes on and stays on all the
time whenever the ignition is switched on.

— Improper installation of child restraints can
reduce their effectiveness or even prevent
them from providing any protection.
— An improperly installed child restraint can
interfere with the airbag as it deploys and
seriously
injure or even kill the child - even
with an Advanced Airbag System.
— Always carefully follow the manufacturer's
instructions provided with the child seat or
carrier.
— Always make sure that there is nothing on
the front passenger seat that will cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that
the seat is occupied by a person when it is
not, or to signal that it is occupied by some-
one who is heavier than the person actually
sitting on the seat. The presence of addi-
tional objects could cause the passenger
front airbag to be turned on when it should
be off, or could cause the airbag to work ina
way that is different from the way it would
have worked without the object on the seat.



ZA WARNING
To reduce the risk of serious injury, make sure
that the PASSENGER AIR BAG OFF 3; light
will be displayed whenever a child restraint is
installed on the front passenger seat and the
ignition is switched on.
— If the PASSENGER AIR BAG OFF %; light
does not stay on, perform the checks descri-
bed > page 200, Monitoring the Advanced
Airbag System.
— Have the airbag system inspected by your
Audi dealer immediately.
— Always carefully follow instructions from
child restraint manufacturers when instal-
ling child restraints.

ZA WARNING
If, in exceptional circumstances, you must in-
stall a forward or rearward-facing child re-
straint on the front passenger's seat:
