- Accident statistics have shown that chi l­
dren are generally safer in the rear seat
area than in the front seating posit ion.
- For their own safety, all children, espe­
cially 12 years and younger, should al­
ways ride in the back properly restrained
for their age and size.
Advanced front airbag system
Your veh icle is equipped with a front Advanced
A irbag System in compl iance with Un ited
States Federal Motor Vehicle Safety S tandard
208 as applicable a t the t ime yo ur vehicle was
manufactured .
The front Advanced Airbag System supple­ ments the safety belts to provide addit ional
protection fo r the driver's and front passeng­
er 's heads and upper bodies in fronta l crashes.
The airbags inflate only in fronta l impacts
when the vehicle dece leration is high enough .
The front Advanced Airbag System for the
front seat occupants is not a substitute for
your safety be lts. Rather, it is part of the over ­
all occupant restraint system in your vehicle .
A lways remember that the airbag system can
only help to protect you, if you are s itting up­
right, wear ing you r safety belt and wearing it
properly . This is why you and your passenge rs
must always be properly restra ined, not just
because the law requires you to be .
The Advanced Airbag System in your veh icle
has been certified to meet the " low r isk" re ­
qu irements for 3 and 6 year-o ld children on
the passenge r side and very small adu lts on
the dr iver side. The low ris k deploymen t crite­
ria are intended to he lp red uce the risk of in ­
ju ry through interaction with the front airbag
that can occur, for example , by being too
close to the steering whee l and instrument
panel when the airbag inflates.
I n addition, the system has been certif ied to
comp ly w ith the "suppression" requi rements
of the Safety Standard, to turn
off the front
a irbag for infants 12 months old and yo unger
who are restra ined on the front passenger seat in child restrain
ts that are listed in the
Standard
¢ page 154, Child restraints and
Advanced Airbags.
"Suppress ion" requires the fron t airbag on the
passenger side to be turned
off if :
- a child up to about one year of age is re­
s trained on the front p assenger sea t in one
of the rear -fac ing or fo rward -facing infan t
restraints listed in Federal Motor Vehicle
Safety Standard 208 with which the Ad­
vanced Airbag System in your veh icle was
cert ified. For a listing of the child restraints
that were used to certify your vehicle's com­
plia nce w ith the US Safety Standard
¢page 154,
-weight less than a thresho ld level stored in
the control unit is detected on the front pas ­
senger seat .
When a person is detected on the front pas­
senger seat, weighing more than the total
we ight of a ch ild that is about
1 year old re­
stra ined in one of the rear-facing o r forward­
facing infant restraints ( listed in Fede ral Mo­
tor Vehicle Sa fety Standa rd 208 w it h which
t h e Advan ced Airbag Sys tem in yo ur vehicle
was certif ied), the front airbag on the passen­
ger side may or may not deploy .
T he
PASSENGER AIR BAG OFF light comes on
when the electro nic contro l unit de tects a to­
ta l we ight on the front passenger seat that re ­
quires the front airbag to be t urned
off . If the
PASSENGER AIR BAG OFF light does not
come on, the front a irbag on the passenger
s ide has not been t urned
off by the contro l
unit and ca n dep loy if the control u nit senses
an impact that meets the cond itions stored in
its memory.
If the total weight on the front passenger
seat is more than that of a typical 1 year-old, but less than the we ight of a small adult, the
front a irbag on the passenger side may dep loy
(the
PAS SENG ER AIR BAG OFF light does not
come on) .
For example, the airbag may deploy if: ..,_

-Occ upants who are unbelted, out of posi­
t ion or too close to the airbag can be
seriously injured by an airbag as it un­
folds with great force in the blink of an
eye
¢ page 132.
A WARNING
-
A child in a rearward-facing child safety
seat insta lled on the front passenger seat
w ill be seriously injured and can be k illed if
the front a irbag in flates - even with an Ad­
vanced Airbag System .
- The inflating a irbag w il l hit the child
sa fety sea t or infant carrier w ith g reat
f orce and w ill smash the ch ild safety seat
and child against the backrest , cente r
armrest, door or roof .
- Always install rear -facing child sa fety
seats on the rear seat .
- If you mus t install a rearward facing
child safety seat on the front passenger
seat because of exceptional circ umstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im ­
med iately install the rear-facing child
safety seat in a rear seating position a nd
have the a irbag system inspected by you r
authori zed Au di dealer .
A WARNING
Objects betwee n you and t he a irbag will
increase the risk of in jury in a crash by in­
t erfering wi th the way the air bag un folds
or by being pushed into you as the a irbag
inflates.
- Never hold th ings in your hands or on
yo ur lap when the vehicle is in use.
- Never transport i tems on or in the area
of the front passenge r seat . Objects
cou ld move into the area of the front air­
bags dur ing braking or other s udden ma­
neuver and become dangerous projec­
t il es that can cause serious personal in­
jury if the airbags inflate .
- Never place or attach accessories or oth­
er objects (such as cupholders, te le­
phone brackets, large, heavy or b ulky ob -
-
Airbag system 141
jects) on the doors, ove r o r near the area
marked "AIRBAG" on the steering wheel,
instrument panel, seat backrests or be­
tween those areas and yourself . These
objects could cause in ju ry in a c rash , es ­
pecia lly when the airbags infla te .
- Never recline the front passenger 's sea t
to transport objects. Items can a lso
move into the area of the s ide a irbag or
the front a irbag du ring bra king or in a
sudden maneuve r. O bje cts ne ar the air­
bags can become projec tiles and cause
in jur y, partic ula rly when the seat is re ­
clined .
A WARNING
The fine dust create d when air bags deploy
can cause breathing prob lems for people
with a history of asthma or other breath­ ing cond itions .
- To reduce the risk of breath ing problems,
those with asthma or other respiratory conditions shou ld get fresh air r ight
away by getting o ut o f the veh icle or
open ing windows or doors.
- If you are in a collision in which airbags
deploy, was h your hands and face with
mild soap and wate r before ea ting.
- Be ca reful not to get the dust into your
eyes, o r into any c uts or sc ratches .
- If the resid ue should get into your eyes,
f lush them w ith wate r.

-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-
Airbag system 145
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-
ch lorate. 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
•
•

146 Airbag system
example, increase the force levels measured
by the sensors and make the airbag system
deploy in crashes in which it would not deploy if the changes had not been made. Other
kinds of changes may reduce the force levels
measured by the sensors and prevent the air ­
bag from deploying when it should.
A WARNING ,.
Changing the vehicle's suspension includ­
ing use of unapproved tire-rim combina­
tions can change Advanced Airbag per­
formance and increase the risk of serious
personal injury in a crash.
- Never install suspension components
that do not have the same performance
characteristics as the components origi­
nally installed on your vehicle.
- Never use tire-rim combinations that have not been approved by Audi.
~ WARNING
-
Items stored between the safety belt
buckle and the center console can cause
the sensors in the buckle to send the
wrong information to the electronic con­
trol module and prevent the Advanced Air ­
bag System from working properly .
- Always make sure that nothing can inter-
fere with the safety belt buckles and that
they are not obstructed.
Knee airbags
Description of knee a irbags
Applies to vehicles: with knee airbags
The knee airbag system can provide supple­
mental protection to properly restrained
front seat occupants .
Fig. 153 Driver 's knee airbag
The driver knee airbag is in the instrument
panel underneath the steering wheel
¢ fig. 153, the knee airbag for the passenger
is at about the same height in the instrument
panel underneath the glove compartment.
The knee airbag offers additional protection
to the driver 's and passenger's knees and up­
per and lower thigh areas and supplements
the protection provided by the safety belts.
If the front airbags deploy, the knee airbags
also dep loy in frontal collisions when the de­
ployment threshold stored in the control unit
is met
¢ page 140, More important things to
know abou t front airbags .
In addition to their normal safety function,
safety belts help keep the driver or front pas­
senger in position in a frontal collision so that
the airbags can provide supplemental protec­
tion.
The airbag system is not a substitute for your
safety belt . Rather, it is part of the overall oc ­
cupant restraint system in your vehicle. Al­
ways remember that the airbag system can
only help to protect you if you are wearing
your safety belt and wearing it properly . This
is why you should always wear your safety
belt, not just because the law requires you to
do so
r::!;> page 123, General notes. ..,.

148 Airbag system
Fully inflated airbags in combination with
properly worn safety belts slow down and lim­
it the occupant's forward movement and help
to reduce the risk of injury.
Important safety instructions on the
knee airbag system
Applies to vehicles: with knee airbags
Airbags are only supplemental restraints. Al­
ways wear safety belts correctly and ride in a
proper seating position.
There is a lot that you and your passengers
must know and do to help the safety belts and
a ir bags to provide supplemental protection .
A WARNING
An inflating knee airbag can cause serious
injury. Wearing safety belts incorrectly and
improper seating positions increase the
r isk of serious personal injury and death
whenever a vehicle is being used.
- The knee airbag system cannot protect
you properly if you are seated too close
to any of the airbag locations. When ad­
justing their seat positions, it is impor­
tant that both the driver and the front
passenger keep their upper bodies and
knees at the following minimum safe
distances:
- at least 10 inches (25 cm) between the
chest and the steering wheel/instru­
ment panel.
- at least 4 inches (10 cm) between the
knees and the lower part of the instru­
ment panel.
- T he risk of personal injury increases if
you lean forward or to the side, or if the
seat is improperly positioned and you are
not wearing your safety belt. The risk in­
creases even more should the airbag de­
ploy.
-Always make sure that the knee airbag
can inflate without interference. Objects
between you and the airbag can increase
the risk of injury in an accident by inter­
fering with the way the airbag deploys or by being
pushed into you as the airbag
deploys.
- Never let anybody, especially children
o r anima ls ride in the footwell in front
of the passenger seat. If the airbag de­
ploys, this can result in serious or fatal
injuries.
- Never carry objects of any kind in the
footwell area in front of the dr iver's or
passenger's seat. Bulky objects (shop­
ping bags, for example) can interfere
with or prevent proper deployment of
the airbag. Small objects can be
thrown through the vehicle if the air­ bag deploys and injure you or your pas­
sengers.
- Make sure there are no cracks, deep
scratches or other damage in the area of
the instrument panel where the knee air­
bags are located.
- If ch ildren are incorrectly seated, their
risk of injury increases in a collision

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
Fig. 155 Sid e airbag location in the driver's seat
The side airbags are located in the sides of the
front seat backrests¢
fig. 155. They are iden­
tified by the word "AIRBAG".
The side airbag system basically consists of:
-the electronic contro l module and external
side impact sensors ..,.

-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.
@ 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
M N United States Federal Motor Vehicle Safety er
~ Standard (FMVSS) 208 as applicable at the ,....,
~ time your vehicle was manufactured .
,....,
"' ,....,
Child Safety 153
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 power 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
help 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 water 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 171
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 the 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 173, fig. 166 or~ page 173,
fig. 167. 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:
Anti-lock bra king sy stem (ABS )
ABS prevents the whee ls from locking up
when brak ing. T he vehicle can st ill be steered
even dur ing hard braking. App ly steady pres­
su re to the brake peda l. Do not pump the ped­
al. A pulsing in the brake pedal ind icates that
the system is helping you to brake the veh icle .
Brake assi st system
The brake ass ist system can decrease braking
distance. It increases brak ing power when the
drive r presses the brake peda l quickly in emer­
gency s ituations. You must press and hold the
brake pedal unti l the s ituation is over. In
vehicles with adaptive c ruise control*, the
brake assis t system is more sensitive if the
•
•

172 Intelligent technology
distance detected to the vehicle ahead is too
smal l.
Anti-slip regulation (ASR )
ASR reduces eng ine power when the drive
wheels begin to spin and adapts the fo rce to
the road condit ions. This makes it eas ier to
start, accelerate and drive up hills .
Electronic differential lock (EDL )
The EDL brakes wheels that are spinn ing and
transfers the d rive powe r to the other wheels.
This f unct ion is available up to abo ut 60 mph
(100 km/h) .
In extreme cases, ED L automat ica lly switches
off to help keep the brake on the braked whee l
from ove rheating. EDL wi ll switch on aga in a u­
tomatically when conditions have returned to
norma l.
Steering recommendation
The ESC helps to stabilize the ve hicle by
changing the steering to rque.
In vehicles with dynam ic steeri ng*, ESC also
helps to stabilize the stee ring in critical s itua­
tions.
Select ive wheel torque control
Selective whee l torque control is used when
driving on curves . The front wheel on the in­
side of the curve or both wheels on the inside
of the curve are braked selective ly as needed.
This a llows mo re prec ise d riving in curves. The
appl icable system may no t activate when d riv­
i ng in wet or snowy condi tions.
A WARNING
- The ESC and its integrated systems can ­
not overcome the laws of physics. This is especia
lly important on slippery o r wet
roads. If the systems begin acting to sta­
bilize your veh icle, you should immedi­
ately change your speed to match the
road and traffic cond itions. Do not let
the increased safety provided by these
systems tempt you to take risks. Do ing
so will in crease the r is k of a loss of vehi­
cle control, collision and serious person al
in juries.
- Always adap t your speed to road, traffi c
and weather conditions . The risk of los ­
ing control of the vehicle increases when
driving too fast, especially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead. The ESC and its integrated sys­
tems cannot a lways p revent collisions -
there is still a risk of acc idents!
- Always accelerate with special care on
even, smooth s urfaces such as those that
are wet or covered with ice and snow.
T he drive w heels can spin even w ith
these assistance sys tems that cannot al­
ways he lp to re duce the risk of loss of ve ­
h icle control.
(D Tips
- ABS and ASR o nly wo rk correctly when
a ll four wheels are equipped wi th iden ti­
c al tires. D ifferen t tire sizes can lead to a
reduction in engine powe r.
- Yo u may hear noises when the systems
