Driving safety
For detailed information on how to adjust the
driver's seat, see
¢ page 61.
A WARNING
Drivers who are unbelted, out of position or
too close to the airbag can be seriously in­
jured by an airbag as it unfolds. To help re­
duce the risk of serious personal injury:
- Always adjust the driver's seat and the
steering wheel so that there are at least
10 inches (25 cm) between your breastbone
and the steering wheel.
- Always adjust the driver's seat and the
steering wheel so that there are at least
4 inches (10 cm) between the knees and the
lower part of the instrument panel.
- Always hold the steering wheel on the out­
side of the steering wheel rim with your
hands at the 9 o'clock and 3 o'clock posi­
tions to help reduce the risk of personal in­
jury if the driver's airbag inflates.
- Never hold the steering wheel at the
12 o'clock position or with your hands at
other positions inside the steering wheel
rim or on the steering wheel hub. Holding
the steering wheel the wrong way can cause
serious injuries to the hands, arms and head if the driver's airbag deploys.
- Pointing the steering wheel toward your face decreases the ability of the supplemen­
tal driver's airbag to protect you in a colli­
sion.
- Always sit in an upright position and never
lean against or place any part of your body
too close to the area where the airbags are
located.
- Before driving, always adjust the front seats and head restraints properly and make sure
that all passengers are properly restrained.
- Never adjust the seats while the vehicle is
moving. Your seat may move unexpectedly
and you could lose control of the vehicle.
- Never drive with the backrest reclined or
tilted far back! The farther the backrests are
tilted back, the greater the risk of injury due
to incorrect positioning of the safety belt and improper seating position.

Proper seating position for the front
passenger
The proper front passenger seating position is
important for safe, relaxed driving .
For your own safety and to reduce the risk of in­
jury in the event of an accident, we recommend
that you adjust the seat for the front passenger
to the following position :
.,. Adjust the angle of the seatback so that it is in
an upright position and your back comes in full
contact with it whenever the vehicle is moving.
.,. Adjust the head restraint so the upper edge is
as even as possible with the top of your head.
If
that is not possible, try to adjust the head re­
straint so that it is as close to this position as
possible
¢ page 62.
.,. Keep both feet flat on the floor in front of the
front passenger seat.
.,. Fasten and wear safety belts correct­
ly¢
page 248.

front passenger's seat, see ¢
page 61.
A WARNING
Front seat passengers who are unbelted, out
of position or too close to the airbag can be
seriously injured or killed by the airbag as it
unfolds. To help reduce the risk of serious
personal injury:
- Passengers must always sit in an upright po­
sition and never lean against or place any part of their body too close to the area
where the airbags are located.
- Passengers who are unbelted, out of posi­
tion or too close to the airbag can be seri­
ously injured by an airbag as it unfolds with
great force in the blink of an eye.
- Always make sure that there are at least 10
inches (25 cm) between the front passen-
ger's breastbone and the instrument panel.
Ill>

-Always make sure that there are at least
4 inches (10 cm) between the front passen­
ger's knees and the lower part of the instru­
ment panel.
- Eac h passenger must always sit on a seat of
t h eir own and properly fasten and w ear the
safety belt belonging to that seat.
- Before driving, always adjust the front pas­
senger seat and head restraint properly.
- Always keep your feet on the floor in front
of the seat. Never rest them on the seat, in­
strument panel, out of the window, etc. The
airbag system and safety belt will not be
able to protect you properly and can even in­
c rease the risk of injury in a crash.
- Never drive with the backrest recli ned or
t il ted fa r bac k! The farther the backrests are
t il ted back, the greater the risk of i njury due
to incorrect posi tioning of the safety bel t
and improper seating position.
- Children must always ride in child safety

Proper seating positions for passengers in
rear seats
Rear seat passengers must sit upright with both
feet on the floor consistent with their physical
size and be properly restrained whenever the ve­
hicle is in use.
To reduce the r isk of injury caused by an incorrect
seating position in the event of a sudden braking
maneuver or a n accident, you r passengers on the
rear bench seat must always observe the follow­
in g:
.,. If there are passengers on the outer rear seats,
adjust the head restraints so the upper edge is
as even as possible with the top of your head. If
that is not poss ible, try to adjust the head re­
straint so that it is as close to this position as
poss ible.
If there is a passenger in the ce nte r
rea r seat, slide the head res traint upward

_&. WARNING
Passengers w ho are improperly seated on the
rear seat can be serio usly inju red in a crash.
- Each passenge r must always sit on a seat of
their own and properly fas ten and wear the
safety bel t belonging to tha t seat.
- Safety bel ts only offer maxim um protect ion
when the seatba ck is securely latched in t he
upright pos ition and the safe ty belts are
properly positioned on the body. By not sit­
ting upright, a rear seat passenger increases
the risk of personal injury from improper ly
positioned safety belts!
- Always ad just the head restraint proper ly so
that it can give maximum protection.

A WARNING
All seats are equipped with head restraints .
Dr iv ing without head restraints or with head
restraints that are not proper ly adjusted in­
creases the risk of ser ious or fatal neck injury
dramatically . To help reduce the r isk of injury:
- Always dr ive with the head restraints in
place and properly adjusted.
- Every person in the vehicle must have a
properly adjusted head restra int.
- Always make sure each person in the vehicle properly adjusts their head restraint. Adjust
the head restra ints so the upper edge is as
even as possib le w ith the top of your head.
If that is not possib le, t ry to adjust the head
restra int so that it is as close to t his position
as possib le.
- Never attempt to adjust head restrai nt

mus t adjust the driver headrest for any rea­
son, fi rst stop the vehicle sa fely before at ­
tempting to ad just the head restra int .
- C hildren must always be p roper ly restrained
in a chi ld restraint that is appropriate fo r
their age and size

Examples of improper seating positions
-
The oc cupant restraint system can only reduce
the risk of injury if vehicle occupants are properly
seated .
Imp roper seating positions can cause se rious in­
jury or deat h. Safety belts can only work when
they are proper ly positioned on the body. Im ­
proper seating positions reduce the effectiveness
of safety belts and w ill even increase the r isk of
in ju ry and death by moving the safety be lt to crit­
ical areas of the body. Improper seating posit ions
also increase the risk of ser ious injury and death
when an airbag deploys and strikes an occupant
who is not in the prope r seat ing pos ition . A driver
240
is responsible fo r the safety o f all veh icle occu ­
pants and especia lly for children. Therefore :
~ Never allow anyone to assume a n incorrect
seating posi tion when the vehicle is being used
q _& .
The following bulletins list on ly some samp le po ­
s itions that w ill increase the r is k of se rious injury
and death. Our hope is that these examples wi ll
make yo u more aware of seating positions that
are dangerous.
Therefore , whenever the vehicle is moving :
-neve r sta nd up in the vehicle
- neve r stand on the seats
- never k neel on the seats
- never ride w it h the seatback recl ined
- never lie down on the rear seat
- never lean up against the instrument panel
- neve r sit on the edge of the seat
- neve r sit sideways
- neve r lean out the w indow
- never put your feet out the window
- neve r put your feet on the instrument panel
- never rest your feet on the seat c ushion or back
of the seat
- never ride in the footwell
- never ride in the cargo area
A WARNING
Imp roper seating positions inc rease the risk
of ser ious personal inju ry and death whenever
a veh icle is being used.
- Always make sure that all veh icle occupants
stay in a proper seating posit ion and a re
proper ly restrained whenever the vehicle is
be ing used.

of injury in an accident by interfering with the
way the airbag deploys or by being pushed in­
to you as the airbag deploys.
- No persons (children) or animals shou ld 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
Pedals
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 circ uit fails, increased brake pedal trav­
e l is required to bring the vehicle to a full stop.
,8. WARNING
-
Peda ls 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 cou ld 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.
Driving safety
Floor mats on the driver side
Always use floor mats that can be securely at­ tached to the floor mat fasteners and do not in­
terfere with the free movement of the pedals .
""Make sure that the floor mats are properly se-
cured and cannot move and interfere with the pedals~ .&_.
Use only floor mats that leave the pedal area un­
obstructed and that are firmly secured so that
they cannot slip out of position . You can obtain
suitable floor mats from your authorized Audi
dealer.
Floor mat fasteners are installed in your Audi.
Floor mats used in your vehicle must be attached
to these fasteners. Properly securing the floor mats will prevent them from sliding into posi­
tions that could interfere with the pedals or im ­
pair safe operat ion of your vehicle in other ways .
,8. WARNING
=
Pedals that cannot move freely can result in a
loss of vehicle control and increase the risk of
serious personal injury.
- Always make sure that floor mats are prop­
erly secured.
- Never p lace or install floor mats or other
floor coverings in the vehicle that cannot be
properly secured in place to prevent them
from slipping and interfering with the ped­
als or the ability to control the vehicle.
- Never place or install floor mats or other
f loor coverings on top of already installed
f loor mats . Additional floor mats and other
coverings will reduce the size of the pedal
area and interfere with the pedals.
- Always proper ly reinsta ll and secure floor
mats that have been taken out for cleaning.
- Always make sure that objects cannot fall
into the driver footwell whi le the vehicle is
mov ing. Objects can become trapped under
the brake pedal and accelerator pedal caus­ ing a loss of vehicle control.

Never rely on airbags alone for protection. Even
when they deploy, airbags provide on ly additional
protection. Airbags are not supposed to dep loy in
all kinds of accidents. A lthough your Audi is
equipped with airbags, all vehicle occupants, in­
cluding the dr iver, 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 offer protect ion in those accidents in w hich
a ir bags are not supposed to deploy or when they
have already deployed. Unbelted occupants can
also be thrown o ut of the vehicle where even
more severe or fatal injur ies can occur.
It is also important for the rear passengers to
wear safety belts correctly . Unbelted passengers
in the rear seats endanger not only themse lves
but also the driver and other passengers
¢fig . 212. In a frontal collision they will be
thrown forward violently, where they can hit and
injure the driver and/or front seat passenger .
Safety belts protect
People think it's possible to use the hands to
brace the body in a minor collision. It 's simply
not true!
Fig. 213 Driver is correct ly restra ined in a sudden b rak ing
maneuver
Safety belts used properly can make a big differ­
ence. Safety belts he lp to keep passengers in
thei r seats, gradually reduce energy leve ls ap­
plied to the body in an acciden t, 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
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 ene rgy over a longer period of time, the
safety belts make the forces on the body more
"tolerab le" and less likely to ca use injury .
Although these examples are based on a frontal collision, safety be lts can also substantially re ­
duce the r isk of injury in other k inds of crashes.
So, whether you're on a long trip or just go ing to
the corner store, always buckle up and make sure
others do, too. Acc iden t statist ics 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
safety belts also greatly increases the ability of
the supp lemental airbags to do their job in a col­
lision. For this reason, wearing a safety belt is le­
gally required in most count ries including much
of the United States and Canada .
Although your Aud i 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 act i­
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 air bag
systems in your Audi . So, always wear your safety
belt and make sure everybody in your vehicle is
properly restrained!
Important safety instructions about safety
belts
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.

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 pos itioned on the body .
Improper seating positions reduce the effect ive­
n ess of safety be lts and will even inc rease the
ris k of injury and death by mov ing the safety bel t
to cr it ica l areas of the body. Imp roper seating
positions also increase the risk of serious inj ury
and death when an airbag deploys and strikes an
occ upant who is not in the co rrect seat ing posi­
tion. A driver is respons ible for the safety of all
vehicle occupants and espec ia lly for children.

Pyrotechnic safety belt pretens ioners
All safety belts except for the safety belt in the
center seat position of the rea r seat are equipped
with safety belt pretensioners. The sys tem is acti­
va ted by sensors in front, side and rear-end co lli­
s ions of great severity and in a rollover. Th is

(!) Tips
The pyrotechn ic safety belt pretensioners can
on ly be act ivated once.
- The safety belt pretensione rs do not deploy
in minor frontal, side and rear-end colli­
sions.
- When the pyrotechn ic safety belt preten­
sioners are activated, a fine dust is released.
Th is is normal and is not caused by a fire in
the vehicle .
- The relevant safety requirements must be
observed when the vehicle or components

to pass on the information to you.
- Be sure to observe all safety, environmental
and other regulations if the vehicle or indi­
vidual parts of the system, particularly the
safety belt or airbag, are to be disposed . We
recommend you have your authorized Audi
dealer perform this service for you.
Service and disposal of safety belt preten­
sioner
The safety belt pretensioners are parts of the
safety belts on your Audi. Installing, removing,
servicing or repairing of belt pretensioners can
damage the safety belt system and prevent it
from working correctly in a collision.
There are some important things you have to
know to make sure that the effectiveness of the
system will not be impaired and that discarded
components do not cause injury or pollute the
environment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal injury
and death by preventing a safety belt preten­
sioner from activating when needed or acti­
vating it unexpectedly :
- The pyrotechnic safety belt pretensioners
can only be activated once.
If pyrotechnic
safety belt pretensioners have been activat­
ed, the system must be replaced.
- Never repair, adjust, or change any parts of
the safety belt system.
- Safety belt systems including safety belt
pretensioners cannot be repaired. Special
procedures are required for removal, instal­
lation and disposal of this system.
- For any work on the safety belt system, we
strongly recommend that you see your au­
thorized Audi dealer or qualified technician
who has an Audi approved repair manual,
training and special equipment necessary.

Airbag system
Important information
Importance of wearing safety belts and
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
9 page 237,
.,. Adjust the front passenger's seat properly
¢page 238,
.,. Wear safety belts properly¢ page 247,
.,. Always properly use the proper child restraint
to protect children ¢
page 2 77.
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. Therefore 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 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 237, Correct
seating position for passengers.
For details on
the operation of the seat adjustment controls
¢page 61.
It 's especially important that children are proper­
ly restrained
¢page 277 .
There is a lot that the driver and the passengers
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
Airbag system
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
thori zed 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 front seat passenger from hitting parts 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 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
