What impairs driving safety?
Safe driving is directly related to the condi­
tion of the vehicle , the driver as well as the
driver's ability to concentrate on the road
without being distracted .
The driver is responsible for the safety of the
vehicle and all of its occupants. If your ability
to drive is impaired, safety r isks for everybody
in the vehicle increase and you a lso become a
hazard to everyone else on the road
~ .&_.
Therefo re:
.. Do not let yourself be distracted by passen­
gers or by using a cellular telephone .
.. NEV ER dr ive when your driving ability is im­
paired (by medicat ions, 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 t ired, under
pressure or when you are stressed .
& WARNING
Impaired driving safety increases the risk
of serious personal injury and death when­
ever a veh icle is being used.

A WARNING
Drivers who are unbelted, out of position
or too close to the airbag can be seriously
injured by an airbag as it unfolds. To help
reduce 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 breast­
bone and the steering wheel.
- Always hold the steering wheel on the
outside of the steering wheel rim with
your hands at the 9 o'clock and 3 o'clock positions to help reduce the risk of per­
sonal injury 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. Hold­
ing the steering wheel the wrong way
can cause serious injuries to the hands,
arms and head if the driver's airbag de­
ploys.
- Pointing the steering wheel toward your
face decreases the ability of the supple­
mental driver 's airbag to protect you in a
collision .
- Always sit in an upright position and nev­
er lean against or place any part of your
body too close to the area where the air ­
bags are located.
- Before driving, always adjust the front
seats and head restraints properly and
make sure that all passengers are prop­
erly restrained.
- Never adjust the seats while the vehicle
is moving . Your seat may move unexpect­
edly and you could lose control of the ve­
hicle.
- Never drive with the backrest reclined or
tilted far back! The farther the backrests
are tilted back, the greater the risk of in- jury due to incorrect positioning of the
safety belt and improper seating posi­
tion.
- Children must always ride in child safety
seats ¢

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
injury in the event of an accident, we recom ­
mend that you adjust the seat for the front
passenger to the following position :
• Move the front passenger seat back as far as
possible . There must be a minimum of
10 inches (25 cm) between the breastbone
and the instrument panel¢,&. .
• 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.
• Applies to vehicles with adjustable head re­
straints: Adjust the head restraint so the up­
per edge is as even as possible with the top
of your head. If tha t is not possible, try to
adjust the head restraint so that it is as
close to this position as possible.
• Keep both feet flat on the floor in front of
the front passenger seat.
• Fasten and wear safety belts correctly

Important things to know
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints. For
airbags to do their job , occupants must al­
ways properly wear their safety belts and be
in a proper seating position.
F or your safety and the safety of your passen­
gers, before driving off, always:
• Adjust the driver's seat and steering wheel
properly
¢ page 127,
• Adjust the front passenger's seat properly
r=; page 61,
• Wear safety be lts properly ¢ page 139,
• Always properly use the proper child re-
straint to protect children¢
page 165.
In a collision airbags must inflate within the
blink of an eye and with considerable force.
The supplemental airbags can cause injuries if
the dr iver or the front seat passenger is not
seated properly . Therefore in order to help the
a ir bag to do its job, it is important, both as a
d river and as a passenger to sit prope rly 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
comp letely and provide supplemental protec­
tion in ce rtain frontal collisions

It's especially important that children are
properly restrained
r=:;page 165.
There is a lot that the driver and the passen­
ge rs can and must do to help the individua l
safety features installed in your A udi work to­
gether as a system.
Proper seating pos ition is important so that
the front airbag on the driver side can do its
job. If yo u have a physical impairment or con- dition that
prevents you from sitting properly
on the driver seat with the safety belt properly
fastened and reaching the pedals , spec ial
modif ications to your vehicle may be necessa­
ry.
Contact your authorized Audi dealer, or call
Audi C ustomer Relations at 1-800-822-2834 .
When the airbag system dep loys , a gas gener­
ator will f ill the airbags, break open the pad­
ded covers, and inflate between the steering
whee l and the dr iver and between the instru­
ment panel and the front passenger. The air­
bags will deflate immediately after deploy­
ment so that the front occupants can see
th rough the windshield aga in without inter­
ruption .
All of this takes place in the blink of an eye , so
fast that many people don't even realize that
the a irbags have deployed . The airbags also
inflate with a great deal of force and nothing
shou ld be in their way when they deploy.
Front airbags in comb ination with prope rly
worn safety belts slow down and limit the oc­
cupant's forward movement. Together they
help to prevent the driver and front seat pas­
senger from hitting parts of the inside the ve­
hicle while reducing the forces acting on the
occupant dur ing the crash. In this way they
help to reduce the risk of injury to the head
and upper body in the crash . A irbags do not
protect the arms or the lower parts of the
body.
Both front a irbags w ill not inflate in all fronta l
collisions . The triggering of the airbag system
depends on the vehicle deceleration rate
caused by the collision and registered by the
electron ic control unit. If this rate is below
the reference value programmed into the con­
trol unit, the airbags will not be triggered ,
even though the car may be bad ly damaged as
a result of the co llision . Vehicle damage, re­
pair costs or even the lack of veh icle damage
is no t necessarily an indication of whether an
airbag should inflate or not .
It is not possib le to define a range of vehicle
speeds that w ill cover every possib le kind and .,.

angle of impact that will always trigger the
airbags, since the circumstances will vary con­
siderably between one collision and another.
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 also not inflate in
side or rear collisions, or in ro ll-overs .
Alwa ys rem ember : Airbags will deploy only
once, and only in certa in kinds of collisions .
Your safety belts are always there to offer pro­
tection in those s ituations in which airbags
are not supposed to deploy , or when they have
a lready deployed ; fo r example , when yo ur ve­
h icle strikes or is struck by another after the
first collision .
This is just one of the reasons why an a irbag is
a supplementary restra int and is not a s ubst i­
tute for a safety belt . The airbag system
works most effectively when used with the
safety belts. Therefore, always properly wear
your safety belts
¢ page 136.
A WARNING
Sitting too close to the steer ing wheel or
instrument panel will decrease the effec­
tiveness of the airbags and will increase
the risk of pe rsonal injury in a co llision .
- Never sit closer than
10 inches (25 cm)
to the stee ring wheel or instrument pan­
el.
- If you cannot sit more than
10 i nches
(25 cm) from the steer ing whee l, investi­
gate whether adaptive equipment may
be available to help you reach the pedals
and increase your seating dis tance from
the steering wheel.
- If you are unrestrained, lean ing fo rward,
sitting sideways or out of position in any
way, yo ur risk of inj ury is much highe r.
- You w il l also receive serio us inju ries and
cou ld even be killed if you are up against
the airbag or too close to it when it in ­
flates -even with an Advanced Airbag.
- To reduce the r isk o f injury when an air ­
bag inflates, a lways wear safety belts

-Always make certain that chi ld ren age 12
or younger a lways ride in the rear seat. If
children are not properly restrained, they may be severe ly inju red or killed when an
airbag inf lates .
- Never let ch ildren ride unrestra ined or
improperly restrained in the vehicle . Ad ­
just the front seats prope rly.
- Never ride with the backrest reclined.
- Always sit as far as possible from the
steer ing whee l or the instrument pane l
¢page 127.
-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 f loor in front of the seat to
he lp prevent serio us in juries to the legs
a nd h ips if the airbag inflates.
- Never recline the front passenger 's seat
to tra nsport objects. Items can a lso
move i nto the area of the s ide a irbag or
the front a irbag du ring bra king or in a
sud den maneuve r. Obje cts ne ar the air­
bags can become projectiles and cause
injury when an airbag inflates.
_&. WARNING ~
A irbags that have de ployed in a crash must
be replaced.
- Use on ly original equipment airbags ap­
proved by Audi and installed by a trai ned

Front airbags
Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat
occupants.
Fig. 153 L ocation of driver airbag: in steer ing wheel
Fig. 154 Locatio n of fro nt passenger's airbag: in the in ­
st rument panel
Your veh icle is equipped with an "Advanced
Airbag System" in compliance with United
States Federal Motor Vehicle Safety Standard (FMVSS) 208 as applicable at the time your
vehicle was manufactured. The safety belts
for the seats have "pretensioners" that help
to take slack out of the belt system. The pre­
tensioners are also activated by the electronic
control unit for the airbag system.
The front safety belts 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 hub
¢ fig. 153 and the airbag for the front
passenger is in the instrument panel
¢ fig. 154 . The general location of the airbags
is marked "AIRBAG".
There is a lot you need to know about the air­
bags in your vehicle . We urge you to read the
detailed information about airbags, safety
belts and child safety in this and the other
c h apters 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 in­
fants and small children.
_&. WARNING
Never rely on airbags alone for protection.
- Even when they deploy, airbags provide
only supplemental protect ion.
-Airbag work most effectively when used
with properly worn safety belts.
- Therefore, always wear your safety belts
and make sure that everybody in your ve­
h icle is properly restrained.
_&. WARNING
-A pe rson on the front passenger seat, es-
pecially infants and sma ll children, will re­
ceive serious injuries and can even be kil­
led by being too close to the airbag when
it inflates .
- 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 under these special conditions is imposs ible in all conceiva­
ble situat ions 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 heavier than the typical one-year
old child is on the front passenger seat
and the other conditions for airbag de­
p loyment are met .

158 Airbag system
-Never attach any objects such as cu­
pholders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners could damage the airbag cover
or change the stiffness or strength of the
material so that the airbag cannot de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system .
- All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including the installation of audio
equipment, cellular telephones and CB
radios, etc.) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work­
shop.
- Never modify the front bumper or parts
of the vehicle body.
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can be activated only
once. After an airbag has inflated, it
must be replaced by an authorized Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only once. After an airbag has been deployed,
it must be replaced with new replace -ment parts designed and approved espe­
cially for your Audi model version . Re­
placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only. Make sure that any airbag service action
is entered in your Audi Warranty
& Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD.
- In accidents when an airbag is deployed,
the vehicle battery separates the alterna­
tor and the starter from the vehicle elec­
trical system for safety reasons with a pyrotechnic circuit interrupter.
- Work on the pyrotechnic circuit inter­ rupter must only be performed by a
qualified dealer -risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.
@ For the sake of the environment
Undeployed airbag modules and preten ­
sioners might be classified as Perchlorate
Material -special handling may apply, see
www .dtsc.ca.gov/hazardouswaste/per­
chlorate. When the vehicle or parts of the restraint system including airbag modules
safety belts with pretensioners are scrap­
ped, all applicable laws and regulations
must be observed. Your authorized Audi
dealer is familiar with these requirements
and we recommend that you have your
dealer perform this service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem performs in a crash. For example, using
tire-rim combinations not approved by Audi, lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag sensors and sent to the electronic control
unit. Some suspension changes can, for

166 Child Safety
-If you must install a rearward facing
child safety seat on the front passenger
seat in exceptional circumstances and
the
PASSENGER AIR BAG OFF light does
not come on and stay on, immediately
install the rearward-facing child safety
seat in a rear seating position and have
the airbag system inspected immediately
by your authorized 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.
- Always follow the manufacturer's in­
structions provided with the child safety
seat or carrier.
- 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 child restraint. The backrest must be adjusted to an upright position .
- Always make sure that the
PASSENGER
AIR BAG OFF
light comes on and stays
on all the time whenever the ignition is
switched on.
(D Tips
Always replace child restraints that were
installed in a vehicle during a crash. Dam­
age to a child restraint that is not visible
could cause it to fail in another collision
situation.
Advanced front airbag system and children
Your vehicle is equipped with a front "Ad­
vanced Airbag System" in compliance with
United States Federal Motor Vehicle Safety
Standard (FMVSS) 208 as applicable at the
time your vehicle was manufactured . The
Advanced Airbag system in your vehicle
has been certified to meet the "low-risk" re­
quirements for 3- and 6-year old children on
the passenger side and small adults on the driver side. The low risk deployment criteria
are intended to reduce the risk of injury
through interaction with the airbag that can
occur, for example, by being too close to the
steering wheel and instrument panel when
the airbag inflates . In addition, the system
has been certified to comply with the "sup­
pression" requirements of the Safety Stand­
ard, to turn off the front airbag for infants up
to 12 months who are restrained on the front
passenger seat in child restraints that are list­
ed in the Standard.
Even though your vehicle is equipped with an
Advanced Airbag system, all children, espe­
cially those 12 years and younger, should al­
ways ride in the back seat properly restrained
for their age and size. The airbag on the pas ­
senger 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 for­
ward-facing child safety seat.
It can be a very
dangerous place for an infant or a larger child
in a rearward-facing seat.
Advanced Airbags and the weight­
sensing mat in the front seat
The Advanced Airbag System in your vehicle detects the presence of an infant or child in a
child restraint on the front passenger seat us­
ing the weight-sensing mat in the seat cush­
ion and the sensor below the safety belt latch
on the front passenger seat that measures the
tension on the safety belt.
The weight-sensing mat measures total
weight of the child and the child safety seat
and a child blanket on the front passenger
seat. The weight on the front passenger seat
is related to the design of the child restraint
and its "footprint", the size and shape of the
bottom of the child restraint as it sits on the
seat. The weight of a child restraint and its "footprint" vary for different kinds of child re -
straints and for the different models of the .,.

Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of veh icle control. It works
only when the eng ine is running. ESC detects
certain difficult driv ing situations, including
when the vehicle is beginning to spin (yaw) out of cont ro l and he lps you to get the vehicle
back under control by select ively b rak ing the
wheels, and/or red ucing engine powe r and
p roviding steering assistance to help hold the
ve hicle on the driver's intended course . The in­
dicator light
DJ in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
phys ics. It will not a lways be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
h elp you master situat ions where there is a
sudden change in the coefficient of fr iction of
the road surface. When there is a sect io n of
d ry road that is s udden ly cove red with water,
slush o r snow, ESC canno t perform the same
way it would on the dry su rface.
If the vehicle
hydroplanes (rides on a c ush ion of wate r in­
stead of the road surface), ESC wi ll not be
ab le to he lp you steer the veh icle because con-
Int ellig ent technolog y 185
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
D uring fast corner ing, particular ly on wind ing
roads, ESC cannot always deal as effectively
with difficult dr iv ing s ituations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic and weather conditions . ESC can­
not override the vehicle's physical lim its, in­
crease the availab le tract ion, or keep a veh icle
o n the road if road departu re is a result of
driver ina ttent io n. Instead , ESC imp roves the
poss ibility of keep ing t he vehicle under con­
trol and on the road during extreme maneu­
vers by using the driver's steering i nputs to
help keep the vehicle go ing in the intended di­
rect ion. If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC is switched on all the time. In certain sit­
uat ions when you need less traction, you can
switch off ASR by pressing the butto n
[ill
~ page 187, fig. 174 or~ page 187,
fig. 175. Be sure to sw itch ASR on aga in when
you no lo nger need less traction.
The following systems are integrated in the
ESC:
