What impairs driving safety?
Safe driving is directly related to the condition of
the vehicle, the driver as well as the driver 's abili­
ty to concentrate on the rood without being dis ­
tracted .
The driver is responsible for the safety of the ve­
hicle and all of its occupants. If your ability to
drive is impaired, safety risks for everybody in the
vehicle increase and you also become a hazard to
everyone else on the road
c:> Li').. Therefore :
• Do not let yourself be distracted by passengers
or by using a cellular telephone .
• NEVER drive when your driving ability is im­
paired (by medications, alcohol, drugs , etc.).
• Observe all traffic laws, rules of the road and
speed limits and plain common sense.
• ALWAYS adjust your speed to road, traffic and
weather conditions.
• Take frequent breaks on long trips. Do not drive
for more than two hours at a stretch.
• Do NOT drive when you are tired, under pres­
sure or when you are stressed.
A WARNING
Impaired driving safety increases the risk of
ser ious personal injury and death whenever a
vehicle is being used.

Correct passenger
seating positions
Proper seating position for the driver
The proper driver seating position is important
for safe, relaxed driving.
Fig. 151 Correct seating posit ion
For your own safety and to reduce the risk of in­
jury in the event of an accident, we recommend
that you adjust the driver's seat to the following position:
• Adjust the driver's seat so that you can easily
push the pedals all the way to the floor while
keeping your knee(s) slightly bent
c:> .&, .
• Adjust the angle of the seatback so that it is in
an upright position so that your back comes in
full contact with it when you drive.
• Adjust the steering wheel so that there is a d is­
tance of at least 10 inches (25 cm) between the
steering wheel and your breast bone
r::!) fig. 151.
If not possible, see your authorized Audi deal­
ership about adaptive equipment.
• Adjust the steering wheel so that the steering
wheel and airbag cover points at your chest and
not at your face.
• Grasp the top of the steering wheel with your
elbow(s) slightly bent.
• 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.
• Fasten and wear safety belts correctly
c:> page 141.
• Always keep both feet in the footwell so that
you are in control of the vehicle at all t imes .

For detailed information on how to adjust the
driver's seat, see
¢ page 59.
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 inflates.
- 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
T he 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

For detailed information on how to adjust the
front passenger's seat, see¢
page 58.
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 . ..,

Driving safety
-Always make sure that there are at least
10 inches (25 cm) between the front pas­
senger 's breastbone and the instrument
panel.
- 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.
- Each passenger must always sit on a seat of
their own and properly fasten and wear 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 be lt will not be
able to protect you properly and can even in­
crease the risk of injury in a crash.
- Never dr ive with the backrest reclined or
ti lted far back! The farther the backrests are
ti lted back, the greater the risk of injury due
to incorrect positioning of the safety belt
and improper seating position.
- Children must always ride in child seats
¢
page 168. Special precautions apply
when installing a child seat on the front passenger seat ¢
page 146.
Proper seating positions for passengers in
rear seats
Rear seat passengers must si t upright with both
feet on the floor consi sten t with their physical
size and be properly restrained whenever the ve ­
hicle is in use .
To reduce the risk of injury caused by an incorrect
seating position in the event of a sudden braking
maneuver or an accident, your passengers on the
rear bench seat must always observe the follow­
ing:
.,. For adjustable head restraints: Adjust the head
restraint so the upper edge is as even as possi ­
ble with the top of your head . If that is not pos­
s ib le, try to adjust the head restraint so that it
is as close to this position as possible
~page 132.

.,. Keep both feet flat in the footwell in front of
the rear seat.
.,. Fasten and wear safety belts properly
q page 141.
.,. Make sure tha t children are always properly re­
strained in a child restraint that is appropriate
for their size and age
q page 168 .
A WARNING
Passengers who are imprope rly seated on the
rear seat can be seriously injured in a crash.
- Each passenger must always sit on a seat of
their own and properly fasten and wear the
safety belt belonging to that seat.
- Safety belts only offer maximum protection
when the safety be lts are properly posi­
tioned on the body and secure ly latched . By
not sitting upright, a rear seat passenger in­
creases the risk of personal injury from im­
properly positioned safety belts!
-Always ad just the head restraint properly so
that it can give maximum protection.
Proper adjustment of head restraints
Correctly adjusted head restraints are an impor­
tant part of your vehicle's occupant restraint sys­
tem and can help to reduce the risk of injuries in
accident situations .
Fig. 152 Head rest raint : viewed from the front
The head restraints must be correctly adjusted to
achieve the best protection .
.,. For adjustable head restraints: adjust the head
restraint so the upper edge is as even as possi-
ble with the top of your head . If that is not pos­
sible, try to adjust the head restraint so that it .,._

is as close to this position as possible.

Adjusting head restraints ¢page 64.
Crash -active head restraints
In the event of a rear -end collision, it is possible
that the crash-active head restraints on the driv­
er's seat and front passenger's seat
1> are trig­
gered. On head restraints that have been trig­
gered, the padding protrudes forwards by several
centimeters. Drive the vehicle to your authorized
Audi dealer without delay and have the function
of the active head restraints restored.
_& WARNING
Driving without head restraints or with head
restraints that are not properly adjusted in­
creases the risk of serious or fatal neck injury
dramatically. To help reduce the r isk of injury:
- Always drive with the head restraints in
place and properly adjusted .
- Every person in the vehicle must have a
properly adjusted head restraint.
- Always make sure each person in the vehicle
properly adjusts their head restraint. Adjust
the head restraint so the upper edge is as
even as possible with the top of your head.
If that is not possib le, try to adjust the head
restra int so that it is as close to this position
as possible.
- Never attempt to adjust head restraint
wh ile driving. If you have dr iven off and
must adjust the driver head rest for any rea­
son, first stop the vehicle safely before at­
tempting to adjust the head restra int.
- Children must always be properly restrained
in a child restraint that is appropriate for
their age and size¢

Driving safety
Examples of improper seating positions
The occupant restraint system can only reduce
the risk of injury if vehicle occupants are properly
seated.
Improper seating positions can cause serious in­
jury or death . Safety belts can only work when
they are properly positioned on the body . Im­
proper seat ing positions reduce the effectiveness
of safety belts and will even increase the risk of
injury and death by moving the safety belt to cr it­
ical areas of the body. Improper seating positions
also increase the risk of serious injury and death
when an airbag deploys and strikes an occupant
who is not in the proper seating position. A driver
is responsible for the safety of all vehicle occu­
pants and especially for children . Therefore:
.,. 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 recl ined
- never lie down on the rear seat
- 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

General information
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety be lts are neces­
sary, how they work and how to adjust and wear
them correctly.
.. Read all the information that follows and heed
all of the instructions and WARNINGS.
&_ WARNING
Not wearing safety belts or wearing them im­
properly increases the risk of serious personal
injury and death.
- Safety belts are the s ingle most effective
means ava ilable to reduce the risk of serious
injury and death in automobile accidents.
For your protect ion and that of your passen­
gers, always co rrectly wear safety be lts
when the vehicle is moving .
- Pregnant women, injured, o r physically im­
paired persons must a lso use safety belts.
L ik e all vehicle occ upants, they are mo re
likely to be serio usly injured i f they do not
wea r safety be lts. The best way to protect a
fetus is to protect the mother -throughout
the ent ire pregnancy .
Number of seats
Your Audi has a total of five seating positions:
two in the front and three in the rear. In some
veh icles, there are four seating positions: two in
the front and two in the rear . Each seating posi­
tion has a safety belt .
&_ WARNING
Not wea ring safety belts or wearing them im­
properly incre ases the risk of ser io us personal
injury and dea th.
- Never st rap more tha n one person, includ­
ing small ch ild ren, into any be lt .
It is espe­
c ia lly da ngerous to place a safety belt over a
child sitting on your lap .
138
-Never let more people ride in the vehicle
than there are safety be lts available .
- Be s ure everyone riding in the vehicle is
properly restrained with a separate safety
be lt or ch ild restraint.
~ Safety belt warning light
Your vehicle has a warning system for the driver
and front seat passenger to remind you about the importance of buckling-up .

Safe ty belts
instrument panel, windshield, or whatever else is
in the way
r:!> fig. 156. This impact with the vehi­
cle interior has all the energy they had just be­
fore the crash.
Never rely on airbags alone for protection . Even
when they deploy, airbags provide only additional
protection. A irbags are not supposed to dep loy in
all kinds of accidents. A lthough your Audi is
equipped w ith 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 offer protect ion in those accidents in wh ic h
airbags are not supposed to deploy or when they
have a lready deployed . Unbel ted occupants can
also be thrown o ut of the veh icle where eve n
mo re severe or fatal injuries can occur .
It is also important for the rear pass engers to
wear safety belts correctly. Unbelted passengers
i n t he re ar seats endanger no t on ly themse lves
but also the drive r and other passengers
~ fig . 157. In a frontal collision they will be
thrown forward violently, where they can hit and
in jure 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!
F ig . 1 58 Driver is co rrectly restrai ned in a sudde n brak ing
m aneu ver
Safety belts used properly can make a b ig d iffer­
ence. Safety belts help to keep passengers in
their seats, gradually reduce energy levels ap-
140
plied to the body in an accident , and help prevent
the uncontrolled movement that can cause seri­
ous injuries. In add ition, sa fety belts red uce the
danger of being thrown out of the vehicle.
Safety be lts attach passengers to the car and g ive
them the benefit of being s lowed down more
gently or "soft ly" thro ugh the "give" in the safety
belts, crush zones and other safety feat ures engi­
neered into today's vehicles. By "absorbing" the
k inet ic energy over a longer per iod of t ime, the
safety belts make the forces on the body more
"tolerab le" and less likely to cause inju ry .
Although these examples are based on a frontal
collision, safety be lts ca n also substantially re ­
duce the r isk o f injury in ot her kinds of crashes .
So, whethe r yo u're on a long trip or just goi ng to
the cor ne r store, a lways b uckle up and make s ure
othe rs do, too. Ac ciden t st at ist ics show that veh i­
cle o ccupants prope rly wearing safety bel ts have
a lowe r risk of being injured and a m uch better
chance of surviving an acc ident . Properly using
safety be lts also great ly increases the ability of
the supp lemental airbags to do their job in a col­
li sion. For this reason, wearing a safety belt is le­
gally required in most countries 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 examp le, are activated only in some
frontal collisions. The front airbags are not act i­
vated in all frontal collisions, in side and rear co l­
li sions, in roll overs or in cases where the re is not
eno ugh deceler ation throug h impa ct to the front
of the vehicle . The same goes for the other a irbag
systems in your Audi. So, always wear your safety
belt and make sure everybody in your vehicle is
properly rest rained!

ware.
- Do not wear the shoulder part of the belt
under your arm or otherwise out of position .
- Several layers of heavy clothing may inter­
fere with correct positioning of belts and re­
duce the overall effectiveness of the system.
- Always keep belt buckles free of anything
that may prevent the buckle from latching
securely .
- Never use comfort clips or devices that cre­
ate slack in the shoulder be lt . However, spe­
cial clips may be requ ired for the proper use
of some child restraint systems.
- Torn or frayed safety belts can tear, and
damaged belt ha rdware can break in an acc i­
dent. Inspect belts regularly.
If webbing,
bind ings, buckles, or re tractors are dam-
Safet y bel ts
aged, have belts rep laced by an authorized
Aud i dea ler or qualified workshop.
- Safety belts that have been worn and loaded
in an accident must be replaced with the
correct replacement safety belt by an au­
thor ized Audi dealer. Replacement may be
necessary even if damage cannot be clearly
seen. Anchorages that were loaded must al­
so be inspected.
- Never remove, mod ify, d isassemble, or try
to repair the safety belts yourse lf.
-Always keep the belts clean . Dirty belts may

risk of injury and death by moving the safety belt
to cr it ica l areas of the body . Improper seating
positions also increase the risk of serious injury
and death when an airbag deploys and strikes an
occupant who is not in the correct seating posi­
tion. A driver is responsible for the safety of all
vehicle occupants and especia lly for children.

nic pretens ioners deploy, the pretensioning
system must be replaced.
