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 road 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. 218 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. 218.
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

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
211

Driving safety
-Never leave your vehicle unattended espe­
cially with the rear lid left open. A child
could crawl into the vehicle through the lug­
gage compartment and close the rear lid be­
coming trapped and unable to get out . Be­
ing trapped in a vehicle can lead to serious
personal injury.
- Never let children play in or around the vehi­
cle.
- Never let passengers ride in the luggage compartment. Vehicle occupants must al­
ways be properly restrained in one of the ve­
hicle's seating positions.
- Air circulation helps to reduce window fog­
ging . Stale air escapes to the outside
through vents in the trim panel, on the left
side of the luggage compartment. Be sure
to keep these slots free and open.
- The tire pressure must correspond to the
load. The tire pressure is shown on the tire
pressure label. The tire pressure label is lo­
cated on the driver's side B·pillar. The tire pressure label lists the recommended cold
tire inflation pressures for the vehicle at its
maximum capacity weight and the tires that
were on your vehicle at the time it was man­
ufactured. For recommended tire pressures
for normal load conditions, please see chap­
ter
¢ page 294.
Tie-downs
The luggage compartment is equipped with four
tie-downs to secure luggage and other items .
Use the tie-dow ns to secure your cargo properly
¢ page 213, Loading the luggage compartment .
In a coll ision, the laws of physics mean that even
smaller items that are loose in the vehicle will
become heavy missiles that can cause serious in­
jury . Items in the vehicle possess energy which
vary with vehicle speed and the weight of the item. Vehicle speed is the most significant factor.
For example, in a frontal collision at a speed of
30 mph (48 km/h), the forces acting on a 10 -lb
(4 .5 kg) object are about 20 times the normal
214
weight of the item. This means that the weight
of the item would suddenly be about
200 lbs. (90 kg) . You can imagine the injuries
that a 200 lbs. (90 kg) item flying freely through
the passenger compartment could cause in a col­
lision like th is.
A WARNING
Weak, damaged or improper straps used to
secure items to tie-downs can fail during hard
braking or in a collision and cause serious per­
sonal injury.
- Always use suitable mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help prevent items from shifting or flying forward as dan­
gerous missiles.
- Never attach a child safety seat tether strap
to a tie-down.

has a defect which could cause a
crash or could cause injury or
death, you should immediately in­
form the National Highway Traffic Safety Administration (NHTSA) in
addition to notifying Audi of
America, Inc.
If NHTSA receives similar com­plaints, it may open an investiga­
tion, and if it finds that a safety
defects exists in a group of
vehicles, it may order a recall and remedy campaign. However,
NHTSA cannot become involved in
individual problems between you,

Airbag syste m
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
ge rs , before driving off, always :
"' Adjust the driver's seat and steering wheel
properly ¢
page 208,
"'Adjust the front passenge r's seat properly
¢ page 54,
"'Wear safety belts p roperly ¢ page 220,
"' Always properly use the proper child restraint
to protect children ¢
page 248.
In a coll is io n, airbags mus t inflate within the
blink of an eye and wi th considerab le force . The
supp lemental airbags can cause injuries if the
driv er or th e front s eat passeng er is not s eated
properly. Therefore in order to he lp the airbag to
do its job, it is important, both as a dr iver and as
a passenger to sit properly at all t imes.
By keeping room between your body and the
steering whee l and the front of the passenger
compartment, the a irbag can inflate fully and
completely and provide supplemental protect ion
in certain frontal collisions¢
page 208, Correct
passenger seating positions .
For details on the
operation of the seat adjustment con trols
¢ page 54.
It's especially important that children are proper ­
ly restra ined
¢ page 248 .
There is a lot that the driver and the passengers
can and must do to help the ind iv idual safety fea­
tures installed in your Audi work together as a
system .
Proper seating posit ion is important so that the
front airbag on the drive r side can do its job. If
you have a physical impairment or cond ition that
prevents you from s itting properly on the driver
seat with the safety be lt properly fastened and
226
reaching the peda ls, or if yo u have concerns w ith
regard to the function or operation of the Ad­
vanced Airbag System, please contact your a u­
thori zed Audi dea ler or qua lified workshop, or
ca ll Audi Customer Relations at 1-800-822-2834
for poss ib le modifications to your vehicle .
When the airbag system dep loys, a gas generator
will fill the airbags, break open the padded cov­ ers, and infla te between the steering wheel and
the driver and between the instrument panel and
t h e front passenger . The airbags w il l deflate im­
med iate ly after deployment so that the front oc­
cupants can see t hrou gh the windsh ie ld again
without i nterruption.
All of th is takes p lace in the b link of an eye, so
fast that many people don't even rea lize that the
a irbags have deployed. The airbags a lso infla te
with a g re at deal of force and nothing should be
i n the ir 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 he lp to prevent the driver
and front seat passenger from hitting pa rts of
the ins ide of the vehicle while reduc ing the fo rces
acting on the occupant dur ing the cras h. In th is
way they help to reduce the risk of injury to the
head and uppe r body i n the crash . Airbags do not
protect the arms or the lower pa rts of the body.
Both front airbags will not inflate in all frontal
collisions . The t riggering of the a irbag system de­
pends on the veh icle decelerat ion rate caused by
t h e coll is io n and regis tered by the ele ctroni c con ­
tro l unit . If this ra te is be low the refe rence value
programmed in to the contro l unit, the airbags
will not be trigge red, even tho ugh the car may be
badly damaged as a resu lt of the co llision. Vehi­
cle damage, rep air costs or even the lack of vehi­
cle damage is not necessarily an indication of
whether an a irbag should inflate or not .
Since the circumstances will vary cons iderab ly
between one co llision and another, it is not possi ­
ble to define a range of veh icle speeds that will
cover every poss ible kind and angle of impact
that w ill always t rigger t he a irbags . Important
factors i nclude, for examp le, the nat ure (hard or
soft) of the object which the ca r hits, the angle of
i mp act , vehicle speed , etc. The front airbags will .,.

ro ll-overs.
A lwa ys rememb er: Airbags will deploy only o nce,
and on ly in certain kinds of coll is ions. Your safety
be lts are always there to offer protection in those
situations in which airbags are not supposed to
deploy, or when they have a lready deployed; for
examp le, when your vehicle str ikes or is struck by
another vehicle after the first collis ion.
This is just one of the reasons why an airbag is a
supp lementary restraint and is not a substitute
for a safety belt. The airbag system works most effect ively when used with the safety belts.
Therefore, always properly wear your safety belts
r:::;,page 218.
A WARNING
Sitting too close to the steer ing whee l or in­
st rument panel will decrease the effect ive­
ness of the airbags and will inc rease the risk
o f persona l injury in a co llision.
- Never sit closer than 10 inches (25 cm) to
the steering wheel or instrument panel.
- If you cannot sit mo re than 10 inches
( 2 5 cm) from the steering wheel, inves ti­
gate whethe r adaptive equipment may be
available to help you reach the pedals and
increase your seating distance from the
steering wheel.
- If you are unrest rained, leaning forward, s it­
ting s ideways or out of position in any way,
your risk of in jury is much h igher.
- Yo u will also receive serious injur ies and
cou ld even be killed if you are up against the
airbag or too close to it when it inf lates -
even with an Advanced Airbag.
- To reduce the risk of in jury when an airbag
inflates, a lways wear safety belts p roperly
i=> page 221, Safety belts .
-Always make certain that ch ildren age 12 or
younger always ride in the rear seat. If chil­ dren are not properly restra ined, they may
be severe ly injured o r kill ed when an airbag
inflates .
- Never let children ride unrestrained or im­ prope rly restrained in the veh icle. Adjust the
fro nt sea ts properly.

Airb ag sys tem
-Never ride with the back rest recl ined.
-Always sit as fa r as possible from the steer-
ing wheel o r the instrument panel
r:::;,page208.
- Always sit upright with your back against
the backrest of your seat.
- Never p lace 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 ser ious injuries to the legs and hips if
the airbag inflates.
- Never recline the front passenger's seat to transpo rt objects. Items can also move into
the area of the s ide a irbag or the front air­
bag during braking or in a sudden maneu­
ver. Objects nea r the airbags can become
p roje ct il es and cause injury when an airbag
inflates.
A WARNING
A irbags tha t h ave deployed in a cr ash m ust be

Federal Motor Vehicle Safety Standard
(FMVSS) 208, as well as Canada Motor Vehicle
Safety Standard (CMVSS) 208 as applicable at
the time your vehicle was manufactured. he safe­
ty belts for the seats have "pretensioners" that help to take s lack out of the belt system. The pre­
tensioners are also activated by the electronic
control unit for the airbag system.
The front safety be lts also have load limiters to
help reduce the forces applied to the body in a
crash.
The airbag for the driver is in the steering wheel

There is a lot you need to know about the airbags
in your vehicle . We urge you to read the detai led
i nformation about airbags, safety belts and ch ild
safety in this and the other chapters that make
up the owner's literature. Please be sure to heed
the WARNINGS -they are extremely important
for your safety and the safety of your passengers,
especially infants and small children .
.&_ WARNING -
Never rely on airbags alone for protection.
- Even when they deploy, airbags provide only
supp lemental protection.
- Airbag work most effectively when used
with properly worn safety belts .
- Therefore, always wear your safety belts and make sure that everybody in your vehicle is
properly restrained .
.&_ WARNING
A person on the front passenger seat, espe­
cially infants and small ch ildren, wi ll receive
serious injuries and can even be killed by be­
ing too close to the airbag when it inf lates.
- Although the Advanced Airbag System in
-
your vehicle is designed to turn off the front
passenger airbag if an infant or a small child
is on the front passenger seat, nobody can
absolutely guarantee that deployment un­
der these special conditions is impossible in
all conceivable situations that may happen
during the useful life of your vehicle.
- The Advanced Airbag System can deploy in
accordance with the "low risk" option under
the U.S. Federal Standard if a child that is
heav ier than the typical one-year old ch ild is
on the front passenger seat and the other
conditions fo r airbag deployment are met.
- Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seating pos ition.
- For their own safety, all children, especially
12 years and younger, should always ride in
the back proper ly restrained for their age
and size.

unit monitors the Advanced Airbag System and
turns the airbag indicator light on when a ma l­
function in the system components is detected. The funct ion of the a irbag indicator light is de­
scr ibed in greater deta il below . Because the front
passenger seat contains important parts of the
Advanced Airbag System, you must take care to p revent it from being damaged. Damage to the
seat may preven t the Advanced A irbag for the
fron t passenger seat from doing its job in a
crash .
The front Advanced Airbag System consists
of the follo wing :
-Crash sensors in the front of the vehicle that
measure vehicle acceleration/deceleration to
provide information to the Advanced Airbag
System a bout the severity of the crash.
- An e lectronic 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 "de­
c ides" whether the safety belt pretens ioners
should be activated .
- An Advanced Airbag with gas generator and
control valve for the driver ins ide the steer ing
wheel hub .
- An Advanced Airbag with gas generator and control valve inside the instrument pa nel for
the front passenger.
- A weig ht-sensing mat under the upholstery

transmits this information to the electronic control unit.
A WARNING ,-
Damage to the front passenger seat can pre-
vent the front airbag from working properly.
- Improper repair or disassembly of the front passenger and driver seat will prevent the
Advanced Airbag System from funct ion ing
properly .
- Repairs to the front passenger seat must be
performed by qualified and properly trained
workshop personnel.
- Never remove the front passenger or driver
seat from the vehicle.
- Never remove the upholstery from the front
passenger seat.
