Intelligent Technology Electronic stabilization
control (ESC)
Description
Ele ctronic stabilization control (ESC) supports
driver safety . It reduces the risk of slipping and
improves d riving stability. ESC detects critica l sit ­
uations such as the vehicle oversteering and un­
dersteer ing or the wheels are spinning. The vehi­
cle is stabilized by apply ing the brakes or reduc ­
ing engine torque . When the ESC engages, the
G1 indicator light b links in the instrument clus­
ter.
T he follow ing systems are integrated in the ESC:
Ant i-loc k bra king s ystem (ABS)
ABS prevents the whee ls from locking when brak­
ing. The vehicle can still be steered even during
hard brak ing. Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
b rake pedal indicates that the system is act ing to
stabilize the vehicle .
Brak e a ssist s ystem
The brake assist system can decrease braking dis­
tance. It increases brak ing power when the driver
presses the brake pedal quickly in emergency sit­
uations . You must press and hold the brake pedal
unti l the dangerous sit uat io n is ove r.
Anti-Slip Regulation (ASR )
ASR reduces eng ine power when the drive wheels
begin spinning and ad apts the force to the road
conditions . This makes it easier to start, acceler ­
ate and dr ive up hills .
Electronic differential lock (EDL )
The EDL applies the brakes to a whee l that starts
spinning and transfers the drive power to the
other driving wheel or wheels ( if the veh icle is
equ ipped w ith all wheel dr ive*) . This function is
n ot available at higher speeds .
0 ~ In extreme cases, EDL automatically switches off
~ to keep the brake on the braked wheel from over-N
8 heat ing . The vehicle is still work ing correctly . EDL 0

will swi tch on again automatically when condi­
tions have returned to normal.
Steering recommendation
T he ESC he lps to s tabilize the vehicle by cha nging
t h e steer ing torque .
Selective wheel torque control
Se lective wheel torque control is used when driv­
i ng on curves . The front whee l on the ins ide of
t h e curve or both wheels on the i nside of the
c ur ve are braked se lectively as needed. This al­
lows mo re prec ise dr iving in c urves .
Automatic post -collision braking system
The "automat ic post -collis ion braking system"
can help to reduce the risk of sliding and of addi­
tiona l co llisions after an accident.
If the a irbag
contro l modu le detects a collision above a certa in
vehicle speed, the ve hicle is br ake d by the ESC.
The vehicle does not brake automatically if:
- the dr iver presses the acce lerator pedal, or
- the bra king fo rc e generated by the pressed
brake pedal is greater than the braking force
that would be in itiated by the system, or
- the ESC, the brake system or the veh icle electri­
cal system are not functioning.
A WARNING
- The ESC and its integrated systems cannot
overcome the lim its imposed by natura l
phys ica l laws. This is especially impo rtant
on slippery or wet roads. If the systems be­
gi n a cting to s tabilize yo ur vehicle, you
should immedi ately alter your speed to
match the road and traffic conditions. Do
not let the inc reased safety provided tempt
you into taking risks. This could increase
your r isk o f a collis ion.
- Please note the r isk of a coll is ion increases
when dr iv ing fast, especially t hrough curves
and on slippery or wet roads, and when dr iv­
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre ­
vent co llisions - there is st ill a risk of acci­
dents!

Intellig ent Technology
All wheel drive (quattro)
Applies to: vehicles with all wheel drive
In all wheel drive, all four wheels are powered.
General information
In all whee l drive, the dr iving power is div ided be­
tween all fou r wheels . This happens automatical­
ly depending on yo ur driving behavior as we ll as
the cur rent road conditions . A lso see ¢
page 89 .
The all whee l dr ive concept is des igned for high
engine power. Yo ur vehicle is except iona lly pow­
erfu l and has excellent driving characteristics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre­ cautions
q .&, .
Winter ti res
By using all whee l drive, your veh icle has good
forward motion w ith standard tires in winter con­
ditions . However, using winter or all season tires
on
all four wheels in the winter is recommended,
because th is w ill improve the
braking effect.
Snow chains
If there a re snow chain laws, snow cha ins m ust
also be used on ve hicles with all wheel drive
¢ page 181, Snow chains .
Replacing tires
For vehicle s wi th a ll wheel d rive, o nly wheels wi th
the same roll ing ci rcumfe rence sho uld be used.
Avoid using tires with di fferen t tread depths
¢ page 173, New tires or wheels.
A WARNING
- Also, in vehicles with all whee l drive, adapt
your driving style to the current road and traffic cond itions. Do not let the increased
safety prov ided tempt you into taking r isks,
because this increases the risk of an acc i­
dent.
- The braking ab ility of your vehicle is limited
to the trac tion of the wheels. I n this way, it
is not different from a two w heel d rive vehi ­
cle. Do no t be tempte d to accelerate to a
h igh speed when the ro ad is s lippery, be -
cause t his increases t he risk of an acci den t. ...,

Driving sa fety
• 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 whe n you are stressed .
A WARNING
Impaired driv ing safety inc reases t he risk of
ser ious persona l inju ry 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. 9 8 Correct seating pos it io n
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 :
• Adjus t the dr iver's seat so tha t you can easily
push the pedals all the way to the floor whi le
keeping your knee(s) s light ly bent ~
,A.
• 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 dis­
tance of at least 10 inches (25 cm) between the
stee ring wheel and your breast bone~
fig. 98 .
If no t possib le, see you r authorized Aud i dea le r
about adapt ive eq uipment.
98
• Ad just the steering wheel so that the steer ing
wheel and airbag cover points at your chest and
not at yo ur face .
• Grasp the top of the steering wheel with your
elbow(s) slightly bent.
• Adjust the head restraint so the uppe r edge is
as even as possib le w ith the top of your head .
If
that is not possib le, try to adjust the head re­
strai nt so that it is as close to this pos it io n as
possible.
• Fasten and wear sa fe ty belts correctly
r=>page 109.
• Always keep both feet in the footwell so that
you are in contro l of the veh icle at all t imes .
Fo r de tailed informa tion on how to ad just the
dr ive r's seat,
see r=!) page 42 .
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 unfo lds. To help
re­
duce the risk of serious personal injury:
- Always ad just the driver 's seat and the
steering whee l so that there are at least
10 inches (25 cm) between yo ur breastbone
and the steering wheel.
- Always hold the steering wheel on the out­
side of the steering wheel r im with yo ur
hands at t he 9 o'clock and 3 o'clock posi­
tions to help reduce the risk of personal i n­
jury if the driver's airbag in flates.
- Never hold the stee ring wheel at the
1 2 o'cl ock position o r wi th you r hands at
o ther posi tion s in side the steer ing whee l
rim o r on the steeri ng wheel hub. Holding
the steering wheel the wrong way can cause serious inju ries to the hands, arms and head
if the drive r's airbag dep loys.
- Pointing the steering wheel towa rd your
face decreases the ability of the supplemen­
tal d river 's airbag to protect you in a coll i­
sion.
- Always sit in an upright pos ition and never
lean aga inst or place any part of your body
too close to the area where the airbags are
located.

Why use safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for peo­
ple riding in vehicles .
Fig. 102 Unbelted occupants in a vehicle heading for a wall
Fig. 103 The vehicle crashes into the wall
The physical principles are simple. Both the vehi­
cle and the passengers possess energy which var­ ies with vehicle speed and body weight. Engi­
neers call this energy "kinetic energy."
The higher the speed of the vehicle and the greater the vehicle's we ight, the more energy
that has to be "absorbed" in the crash.
Veh icle speed is the most significant factor. If
the speed doubles from 15 to 30 mph (25 to 50
km/h), the energy increases 4 t imes!
Because the passengers of this vehicle are not us­
ing safety belts
¢fig. 102, they will keep moving
at the same speed the vehicle was moving just
before the crash, until something stops them -
here, the wall¢
fig. 103 .
Safety belts
The same p rinciples apply to people sitting in a
vehicle that is invo lved in a fronta l co llision. Even
at city speeds of 20 to 30 mph (30 to 50 km/h),
the forces acting on the body can reach one ton
(2,000 lbs. or 1,000 kg) or more. At greater
speeds, these forces are even higher.
People who do not use safety belts are a lso not
attached to the ir vehicle. In a frontal collis ion
they will also keep moving forward at the speed
their vehicle was travelling just before the crash .
Of course, the laws of physics don't just apply to
frontal collisions, they determine what happens in all kinds of accidents and collisions .
What happens to occupants not wea ring
safety belts?
In crashes unbelted occupants cannot stop
themselves from flying forward and being in­
jured or killed. Always wear your safety belts!
Fig. 104 A driver not wearing a safety belt is violently
th row n forwar d
Fig. 10S A rear passe nger not wearing a safety belt will fly
forward a nd strike the driver
Unbelted occupants are not able to resist the tre­
mendous forces of impact by holding tight or
bracing themselves . Without the benefit of safe­
ty restraint systems, the unrestrained occupant
will slam viol ently into th e steering wheel, .,.

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 98,
"'Adjust the front passenge r's seat properly
¢ page 99,
"'Wear safety belts p roperly ¢ page 108 ,
"'Always properly use the proper child restraint
to protect children ¢
page 134.
In a coll is io n ai rbags must inflate wi thin the b link
of an eye and with cons iderable force . The sup ­
p lemental airbags can ca use injuries if the driver
or the front seat passenger is not seated proper·
Ly. T herefore in order to help the airbag to do its
job, it is important, both as a dr iver and as a pas­
senger to sit properly at all t imes .
By keeping room between yo ur 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 collis ions ¢
page 98, Correct
passenger seating positions .
For details on the
operation of the seat adjustment controls
¢ page 42.
It's especially important that children a re proper ­
ly restra ined
¢ page 134 .
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
114
reaching the peda ls, special modifications to
your vehicle may be necessary.
Contact yo ur autho rized Aud i dea le r, or call A udi
C u stomer Rela tions at 1-800 -82 2-2834.
When the airbag system dep loys, a gas generator
will fill the airbags, b reak open the padded cov­
ers, and inflate betwee n the steeri ng wheel and
the driver and between the inst rument panel and
the front passenger . The a irbags w ill deflate im­
mediate ly after dep loyment so t hat the front oc ­
cupants can see through the windsh ie ld again
without interruption.
A ll of th is takes p lace in the blink of an eye, so
fast that many people don't even realize that the
airbags have deployed. The airbags a lso inflate
with a great 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 lim it the occupant's forward move­
ment . T ogether they he lp to prevent the driver
a nd front seat passenger from h itti ng pa rts of
t h e inside the veh icle w hile reducing the fo rces
acti ng on the occupant dur ing the cras h. In th is
way they help to reduce the risk of inju ry to the
head and uppe r body i n 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 trigge ring of the airbag system de ­
pends on the vehicle deceleration rate caused by
the collis ion and registered by the electronic con­
tro l unit . If this rate is below the reference value
programmed into the contro l unit, the airbags
will not be trigge red, even though the car may be
badly damaged as a resu lt of the co llision . Vehi­
cle damage, repa ir costs or even the lack of vehi­
cl e damage is not necessari ly an indica tion of
whethe r an a irbag should inflate o r not.
It is not possib le to define a range of vehicle
speeds that w ill cove r every possible k ind and an­
gle of impa ct that will always tr igger the airbags,
s ince the circumst ances w ill vary cons iderably be ­
tween one collision and another. Important fac­
tors include, for example, the natu re (hard or
soft) of the object which the car hits, the angl e of
i mpact, vehicle speed, etc . The front airbags will ..,_

also not inflate in side or rear coll isions, or in
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 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 106.
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.
- All veh icle occupants and especially children
must be restrained properly whenever riding
in a vehicle. An unrestrained or improperly
restra ined child could be injured by stri king
the inte rior or by being ejected from the ve­
hicle d uring a sudden maneuver or impact.
An unrestrained or imp roperly restrained
child is also at greate r risk of inju ry or death
through contact with an inflating airbag .
-If you are unrest rained, leaning fo rwa rd, s it­
t ing s ideways or o ut of pos ition in any way,
yo ur risk of in jury is mu ch h igher.
- Yo u will also receive serious injur ies and
c ou ld even be killed if you are up ag ainst the
airbag or too close to it w hen it inf lates -
even with an Advanced Ai rbag.
-
Airb ag sys tem
-To reduce the r is k of injury when an airbag
inflates, always wear sa fety belts prope rly
r:::;, page 109, Safety belts.
-Always make certain that children age 12 or
younger always ride in the rear seat. If chil­
dren are not properly restrained, they may be severely injured or killed when an airbag
inflates.
- Never let children r ide unrestrained or im­
p roperly restrained in the vehicle. Ad just the
front seats properly.
- Never ride with the back rest recl ined .
- Always sit as far as possible from the steer-
ing wheel or the instrument panel
r:::;, page 98.
-Always sit upright with your back against
the backrest of your seat .
- Never p lace your feet on the instrument
panel or on t he 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 recl ine the front passenger's seat to
transpo rt objects , Items can also mo ve in to
the area of the s ide a irbag or the front air­
b ag d uring braking o r in a sudden maneu­
ver. Obje cts ne ar the airbags can be come
p roject iles and cause injury when an airbag
inflates .
A WARNING ,.___ -
Airbags that have deployed in a crash m ust be
replaced.
- Use on ly original equipment airbags ap­
proved by A udi and installed by a t rained
technician who has the necessary tools and
d iagnostic equipment to properly replace
any airbag in yo ur vehicle and assure system
effect iveness in a crash .
- Never permit salvaged or recycled airbags to
be installed in your vehicle.

Airbag system
Front airbags
Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat occu­
pants.
Fig. 112 Location of driver airbag: in steering whee l
Fig. 113 Location of front passenger's airbag: in th e in­
strument panel
Your veh icle is equipped with an "Advanced Air­
bag System " in compliance with Un ited States
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.
The airbag for the driver is in the steer ing whee l
hub~
fig. 112 and the airbag for the front pas­
senger is in the instrument panel
~fig. 113. Th e
general location of the airbags is marked "AIR­
BAG" .
There is a lot you need to know about the airbags
in your vehicle . We urge you to read the detailed
information about airbags, safety belts and child
safety in this and the other chapters that make
up the owner 's literature. Please be sure to heed
the WARNINGS - they are extreme ly important
118
for your safety and the safety of your passengers,
especially infants and small children.
A WARNING -
Never rely on airbags alone for protection.
- Even when they deploy, airbags provide only
supplemental protection.
- Airbag work most effectively when used with proper ly worn safety belts.
- Therefore, always wear your safety be lts and
make sure that everybody in your veh icle is
proper ly restrained.
A WARNING
A person on the front passenger seat, espe­
cially infants and small chi ldren, will receive
serious injuries and can even be killed by be­ ing too close to the airbag when it inflates.
- Although the Advanced Airbag System in
your veh icle 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 dep loy in
accordance with the "lo w risk" option under
the U.S. Federal Standard if a child that is
heavier than the typical one-year old chi ld is
on the front passenger seat and the other
conditions for airbag deployment are met.
-Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seat ing position.
- For their own safety, all children, especially
12 years and younger, should always ride in
the back properly restrained for their age and size.
Advanced front airbag system -
Your vehicle is equipped with a front Advanced
Airbag System in compliance with United States
Federal Motor Vehicle Safety Standard 208, as
well as Canada Motor Vehicle Safety Standa rd
(CMVSS) 208 as applicable at the time your vehi­
cle was manufactured .

The front Advanced Airbag System supp lements
the safety belts to provide additional protection
for the driver's and front passenger's heads and upper bodies in frontal crashes. The airbags in­
flate only in frontal impacts when the veh icle de­
celerat ion is high enough.
The front Advanced Airbag System for the front
seat occupants is not a substitute for your safety belts. Rather, it is part of the overall occupant re­
straint system in your vehicle. Always remember
that the a irbag system can only help to protect
you, if you are sitting upr ight, wear ing your safe­
ty belt and wear ing it properly. This is why you
and your passengers m ust always be properly re­
stra ined, not just because the law requ ires you to
be .
The Advanced Airbag System i n your veh icle has
been certified to meet the " low r is k" requ ire­
ments for 3 and 6 year-o ld children on the pas­
senger side and very sma ll adults on the driver
side . The low risk dep loyment criteria are intend­
ed to he lp reduce the risk of injury through inter­
action with the front a irbag that can occur, for
examp le, by being too close to the steering wheel
and instrument panel when the airbag inflates .
In addition, the system has been certified to
comp ly w ith the "suppression" requirements of
the Safety Standard, to turn off the front a irbag
for infants 12 months old and younger who are
restrained on the front passenger seat in c hild re­
stra ints that are listed in the Standard
~ page 136, Child restraints and Advanced Air­
bags.
"S uppress ion" requ ires the front a irbag on t he
passenger side to be turned off if:
- a ch ild up to about one year of age is restra ined
on the front passenger seat in one of the rear­
facing o r forward-fac ing infant restra ints listed
in Federal Motor Vehicle Safety Standard
208
with wh ich the Advanced Airbag System in your
vehicle was ce rtified. For a l isti ng of the ch ild
restraints that were used to certify your vehi­
cle's compliance with the US Safety Standard
~ page 136,
Airb ag sys tem
-weight less than a threshold leve l stored in the
control unit is detected on the front passenger
seat.
When a person is detected on the front passen­ ger seat, weigh ing more than the total weight of
a chi ld that is about 1 year old restrained in one
of the rear -facing or forward-fac ing infant re­
straints (listed in Federal Motor Vehicle Safety Standard
208 with which the Advanced A irbag
System in your veh icle was certified), the front
airbag on the passenger side may or may not de­
ploy.
The
PAS SEN GER AIR BA G OFF light comes on
when the electronic control unit detects a tota l
we ight on the front passenger seat that requ ires
the front a irbag to be turned off. If the
P A SSEN ·
GER AIR BAG OFF
light does not come on, the
front airbag on the passenger side has not been
turned off by the con trol unit and can dep loy i f
the control unit senses an impact that meets the
conditions stored in its memory.
If the to tal weight on the front passenger sea t is
more than that of a typ ica l 1 year-old, but less
than the weight of a small adult, the front airbag on the passenger side may deploy (the
PASSEN­
GER AIR BAG O FF
light does not come on).
For e xample , the air bag ma y deplo y if:
- a small ch ild that is heav ier than a typ ica l 1
yea r-o ld child is on the front passenger seat
(regardless of whethe r the child is in one of the
child safety seats liste d
~page 136),
-a child who has outgrown c hild rest raints is on
t he front passenge r seat.
If the front passenger a irbag is turned off, the
PASSENGER AIR BAG OFF light in the center of
t h e in str ument pane l wi ll come on and s tay on.
The front airbag on the passenger side may
not
deploy (the PASSENGER AIR BAG OFF light does
not ill umi nate and s tay lit) if:
- a small adult or teenager is on the front pas­
senger seat
- a passenger who is not s itting upright with
their back against a non -reclined backrest with
their feet on the vehicle floor in front of the
seat is on the front passenger seat . .,,.

more. The function of the system in the front
passenger seat is checked by the electronic con­
trol unit when the ignition is on . The control unit
monitors the Advanced Airbag System and turns
the airbag indicator light on when a malfunct ion
i n the system components is detected . The func ­
tion of the airbag indicator light is descr ibed in
greater detail below . Because the front passen­
ge r seat contains important parts of the Ad­
vanced A irbag System, you m ust take care to p re­
vent it from being damage d. Damage to the seat
may prevent the Advanced Airbag for the front
passenger seat from doing its job in a crash.
The front Advanced Airbag System consists
of the following :
-Crash sensors in the front of the vehicle t hat
measure vehicle acceleration/deceleration to
provide information to the Advanced Airbag
System a bout the severity of the crash.
- An electronic control un it, with integrated
crash sensors for front and side impacts. The
contro l unit "decides" whether to fire the front
airbags based on the information received from
the crash sensors. The control unit a lso "de ­
c ides " whether the safety be lt pretens ione rs
sho uld be activated .
- An Advanced Airbag with gas generator and
contro l valve for the d river ins ide the s teer ing
whee l hub.
- An Advanced Airbag with gas generator and
contro l valve inside the instrument pa ne l for
the fron t passenger.
- A weig ht-sensing mat unde r the upho lstery
padding of the front passenge r seat c ushion
that meas ures the to tal weight on the sea t. The
informa tion registered is sen t continuously to
the e lectronic cont ro l unit to reg ulate dep loy ­
