-Never place or attach accessories or other
objects (such as cupholders, telephone
brackets, large, heavy or bulky objects) on
the doors, over or near the area marked "AIRBAG" on the steer ing wheel, instru­
ment pane l, seat backrests or between
those areas and yourse lf. These obje cts
c ou ld cause injury in a crash, especially
when the airbags inflate.
- Never recline the front passenger's seat to
transport objects. Items can also move into
the area of the side airbag or the front air ­
bag during braking or in a sudden mane u­
ver. Objects near the airbags can become projectiles and cause injury, particu larly
when the seat is reclined.
A WARNING
The fine dust created when a irbags deploy can
cause breathing prob lems for people with a
history of asthma or other breathing condi­
tions.
- To reduce the r isk of breathing prob lems ,
those w ith asthma or other resp iratory con­
ditions should get fresh air r ight away by
gett ing out of the veh icle or opening w in­
dows or doo rs.
- If you are in a coll is io n in which a irbags de­
ploy, wa sh you r hands and face with mild
soap and w ater before eati ng.
- B e caref ul not to ge t the dust into you r eyes,
o r in to any cuts or s cratc he s.
- If the residue should get into you r eyes,
flush them with water.
Monitoring the
Advanced Airbag System
Airbag monitoring indicator light
Two separate indicators monitor the function of
the Advanced Airbag System: the airbag moni­
toring indicator light and the
PASSENGER AIR
BAG OFF
light.
The Advanced Airbag System (includ ing the elec­
tronic control unit, sensor circuits and system
wir ing) is mon itored cont inuo usly to make sure
that it is funct ion ing properly whenever the ign i-
Ai rb ag system
tio n is on . Each time yo u turn on t he ignit ion, the
II airbag monitoring indicator light wi ll come on
for a few seconds (self diagnostics).
The system must be inspected when th e II
indicator light :
-does not come on when the ignition is sw itched
on,
- does not go out a few seconds after you have switched on the ignition, or
- comes on while driving.
If an airbag system malfunction is detected, the
indica to r li gh t will fi rs t st art flashing to catch the
dr ive r's a tten tion a nd then stay o n cont inuo usly
to serve as a constant reminder to have the sys ­
tem inspected immediately.
If a malfu nction occurs tha t turn s the front air­
bag on the p assenger side off, the PASSENGER
AIR BAG OFF light will come on and stay on
whenever the ignition is on.
A WARNING
-
An a irbag system that is not functioning prop-
erly cannot provide supplemental protection i n a frontal crash.
- If the airbag ind icator light r:::;, page 19
comes when the veh icle is being used, have
the system inspected immediately by your
author ized Audi dealer. It is possible that
the airbag will inflate when it is not sup­
posed to, or will not inflate when it s hould.

Repair, care and disposal of the airbags
Parts of the a irbag system are installed at many
d ifferent places on your Audi . Install ing , remov­
ing, servicing or repa iring a part in an area of the
veh icle can damage a part of a n airbag system
and p revent that system from working properly
in a co llision.
There are some important things you have to know to make sure that the effect iveness of the
sys tem w ill not be impaired and that d iscarded
components do not cause injury or pollute the
environment.
A WARNING
-
Improper care, servicing and repair proce­
dures can increase the risk of personal injury
and death by preventing an airbag from de­
ploying when needed or deploying an airbag
unexpectedly :
- Never cover, obstruct, or change the steer­
ing wheel horn pad or a irbag cover or the in ­
strument panel or modify them in any way .
- Never attach any objects such as cupholders
or telephone mountings to the surfaces cov­
ering the airbag units.
- For cleaning the horn pad or instrument panel, use only a soft, dry cloth or one mois­
tened with plain water. So lvents or cleaners
could damage the a irbag cover or change
the stiffness o r strength of the mater ial so
that the airbag cannot dep loy and protect
properly .
- Never repa ir, adjust, or change any parts of
the airbag system.
- All work on the steering wheel, inst rument
panel, front seats or electrical system (in­
cluding the installation of audio equipment,
cellular telephones and CB radios, etc.)
must be performed by a qualified technician
142 who has the training and special equipment
necessary.
- For any work on the airbag system, we
strongly recommend that yo u see your au­
thorized Audi dealer or qualified workshop.
- Never modify the front bumper or parts of
the vehicle body.
- Always make sure that the side airbag can
inflate w ithout interference :
- Never install seat covers or rep lacement
upholstery over the front seatbacks that
have not been specifically approved by
A udi .
- Never use additional seat cushions that
cover the areas where the side a irbags in­
flate.
- Damage to the orig inal seat cove rs or to
the seam in the are a of the side ai rbag
module must a lways be repaired immedi­
ate ly by an authorized Aud i dealer.
- The a irb ag sys tem can be activated only
once . After an airbag has inflated, it mus t
be rep laced by an authorized Audi dealer or
qualif ied technic ian who has the technical
information, training and specia l equipment
necessary.
- The a irbag system can be deployed only
once . After an airbag has been deployed, it
must be replaced with new replacement parts des igned and approved espec ially for
your Aud i model version. Replacement of
comp lete airbag systems or airbag compo­
nents must be perfo rmed by qualified work­
shops only. Ma ke s ure tha t any airbag serv­
ice action is entered in yo ur Audi Warranty
&
Maintenance booklet under AIRBAG RE­
PLACEMENT RECORD.
- In accidents when an airbag is deployed, the
vehicle battery separates the alternator and
the starter from the vehicle electrical sys­
tem for safety reasons with a pyrotechn ic
circuit interrupter .
- Work on the pyrotechnic c ircuit inte rrupt­
er must on ly be performed by a qua lified
dealer -risk of an acc iden t!
- If the vehicle or the circuit interr upter is
scrapped, all app licable safety precautions
must be followed .

All of this takes place in the blink of an eye, so
fast that many people don't even realize that the
airbags have deployed. The airbags also inflate
with a great deal of force and it is important for
occupant safety that nothing should be in their
way when they deploy .
Fu lly inflated airbags in comb ination with proper­
l y worn safety belts slow down and limit the oc­
cupant 's forward movement and help to reduce
the r isk of injury.
Important safety instructions on the knee
airbag system
A pp lies to vehicles: with k nee a irbags
Airbags are only supplemental restraints . Always
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 be lts and airbags
to provide supplementa l protection.
& WARNING
An inflating knee airbag can cause ser ious in­
jury. Wear ing safety belts incorrect ly and im­
proper seati ng positions increase the risk 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 locat ions. When adjusting the ir
seat positions, it is important that both the
driver and the front passenger keep their
upper bod ies and knees at the followi ng
min imum safe distances:
- at least 10 inches (25 cm) between the
chest and the steering wheel/instr ument
panel.
- at least 4 inches (10 cm) between the knees and the lower part of the instru­
ment panel.
- The risk of persona l injury increases if you
lean forward or to the s ide, or if the seat is
improperly positioned and you are not wear­
ing your safety belt . The risk increases even
more should the airbag dep loy.
-
Ai rb ag system
- Always make sure that the knee airbag can
inflate w ithout interference. Objects be­
tween you and the airbag can increase the
risk of injury in an accident by interfer ing
with the way the airbag deploys or by being
pushed into yo u as the a irbag deploys.
- Never let anybody, especia lly children or
animals ride in the footwell in front of the passenger seat. If the airbag deploys, this
can resu lt in serious or fatal injuries.
- Never carry objects of any kind in the foot­
well area in front of the driver's or pas­
senger's seat. Bulky objects (shoppi ng
bags, for example) can i nterfere with or
preve nt proper deployment of the airbag.
Small objects can be thrown through the
vehicle if the airbag dep loys and injure yo u
or you r passengers.
- Ma ke sure there are no cracks, deep scratch­
es or othe r damage in the area of the instr u­
men t pa nel where the knee a irb ags are lo­
ca ted.

GER AIR BAG OFF
light does not come on
and stay on, immediately install the rear­
ward-facing child safety seat in a rear seat­
ing position and have the airbag system in­
spected immediately by your authorized
Audi dealer.
_& WARNING
If, in exceptional circumstances, you must in­
stall 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 man­
ufacturer for use on a front seat with a pas­
senger front and side airbag.
- Always follow the manufacturer's instruc­
tions 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 air­
bag 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 in­
stalled in a vehicle during a crash. Damage 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 "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 Advanced Airbag system in your vehicle has
been certified to meet the "low-risk" require­
ments for 3- and 6-year old children on the pas­
senger side and small adults on the driver side.
The low risk deployment criteria are intended to
152
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
"suppression" requirements of the Safety Stand ­
ard, to turn off the front airbag for infants up to
12 months who are restrained on the front pas­
senger seat in child restraints that are listed in
the Standard.
Even though your vehicle is equipped with an Ad­
vanced Airbag system, all children, especially
those 12 years and younger, should always ride in
the back seat properly restrained for their age
and size. The airbag on the passenger 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 forward-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 de­
tects the presence of an infant or child in a child
restraint on the front passenger seat using the
weight-sensing mat in the seat cushion 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 de­
sign of the child restraint and its "footprint", the
size and shape of the bottom of the child re ­
straint as it sits on the seat . The weight of a child
restraint and its "footprint" vary for different
kinds of child restraints and for the different
models of the same kind of child restraint offered
by child restraint manufacturers.
The weight ranges for the individual types, makes
and models of child restraints that the NHTSA
has specified in the Safety Standard together
with the weight ranges of typical infants and typ-
ical 1 year-old child have been stored in the .,..

Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of sk id­
d ing and loss of veh icle control.
It works only
when the engine is runn ing . ESC detects certain
d ifficult driving situations, including when the ve­
h icle is beginn ing to sp in (yaw) out of control and
he lps you to ge t the vehicle back u nder cont rol by
selectively braking the wheels, and/or reducing
engine power and providing steering assistance
to help hold the vehicle on the driver's intended
course. The indicator light
liJ in the instrument
cluster blinks when ESC is taking action to help
you control the veh icle.
ESC has limitations. It is important to remember
that ESC cannot overcome the laws of physics. It
will not always be able to help out under all con­
d itions you may come up against. For example,
ESC may not always be able to help you master
situations where there is a sudden change in the
coefficient of friction of the road surface. Whe n
there is a section of d ry road that is s uddenly cov ­
ered wi th wa ter, s lush or snow, ESC cannot per­
form the same way it wou ld on the d ry surface . If
the vehicle hydroplanes (rides on a cushion of wa ­
ter instead of the road surface), ESC wi ll not be
ab le to he lp you steer the veh icle because contact
with the pavement has been i nterrupted and the
ve hicle cannot be braked or steered. Dur ing fast
cornering, particula rly on w inding roads, ESC
cannot a lways deal as effect ively with d iff icu lt
d riving situat ions than at lower speeds. When
towing a trailer, ESC is not able to he lp yo u regain
con trol as it wou ld if yo u were not towing a trail­
er .
A lways adjust you r speed and dr iving style to
road, traffic and weather conditions. ESC cannot
override the vehicle's physical limi ts, increase the
170
available traction, or keep a vehicle on the road if
road departure is a result of driver inattention .
Instead, ESC improves the possibility of keeping
the ve hicle under control and on the road dur ing
extreme maneuvers by using the dr iver's steering
i nputs to help keep the vehicle going in the in­
tended direction. If you are traveling at a speed
that causes you to run off the road before ESC
can p rov ide any assistance, you may not expe ri­
ence the benefi ts of ESC.
ESC is switched o n all the time. In ce rtain s itua­
tions when you need less traction, you can switch
off ASR by p ress ing the button [!]¢
page 171,
fig. 153 or ¢page 171, fig. 154. Be s ure to
swi tch ASR on again when you no longe r need
l ess traction .
The following system s are integrated in the ESC:
Anti- lock braking s ystem (ABS )
ABS prevents the wheels from locki ng up when
braking. The vehicle ca n still be steered even dur­
i ng hard braki ng . Apply steady pressure to the
brake pedal. Do not pump t he pedal. A pu lsing in
t h e b ra ke peda l ind icates that the system is he lp­
i ng yo u to b ra ke the vehicle.
Brake assist system
The brake ass ist system can decrease brak ing dis ­
ta nce. It increases braking power when the d river
presses the bra ke peda l quickly in emergency sit­
u at ions. You must press and hold t he b ra ke peda l
u nt il t he s ituation is ove r. In vehicles with adap­
tive cru ise contro l*, the bra ke assist system is
more sensitive if the distance detected to the ve ­
hicle ahead is too sma ll.
Anti-slip regulation (ASR )
ASR reduces eng ine power when the d rive wheels
begin to spi n and adap ts the force to the ro ad
cond it ions . This makes it eas ie r to start, acce le r­
ate and drive up hills.
Electronic differential lock (EDL)
The EDL bra kes whee ls that a re spinn ing and
t ransfers the dr ive power to the othe r drive wheel
o r whee ls if the ve hicle is equippe d wi th a ll-wheel
drive*. T his function is not available at higher
speeds .

M N
0 l­oo
rl I.O
"' N
"' rl
In extreme cases, EDL a utomatica lly switches off
to help keep the brake on the braked whee l from
overheating. EDL w ill switch on again automati ­
cally when conditions have returned to normal.
Steering re commendat ion
The ESC helps to stabilize the ve hicle by chang ing
the steering torque.
I n vehicles with dynamic steeri ng*, ESC also
h e lps to stabilize the steering in critical s itua­
tions .
Electronic interaxle differential lock* /
sel ectiv e wheel torque control*
The electron ic in teraxle d iffe ren tial lock (front
wheel drive) or the selective wheel torq ue contro l
(all wheel drive) operates when driving through
curves. The front whee l on the ins ide of the cu rve
or both whee ls on the inside of the curve are
braked selectively as needed. Thi s allows more
precise driving in curves. The applicable system
may not activate when driving in wet or snowy
conditions .
_&, WARNING
- The ESC and its integrated systems cannot
overcome the laws of physics. This is espe­
ci al ly impo rtant on slippe ry or wet roads. If
the sys tems begin acting to stabilize your
Switching on/off
Smart Technology
veh icle, you shou ld immediately change
your speed to matc h the road and traffic
conditions. Do not let the increased safety
provided by these systems tempt you to
take risks . Do ing so will increase the risk of a
loss of vehicle control, collision and serious
personal injuries.
- Always adapt your speed to road, traffic and
weather conditions. The risk of losing con­
trol of the vehicle inc reases when dr iving
too fast, espec ially through curves and on
slippery or wet roads, and when dr iving too
close to vehicles up ahead . The ESC and its
integrated systems cannot a lways prevent
coll isions -there is sti ll a risk of accidents!
- Always accelerate with special care on even,
smooth su rfaces such as those that are wet
or covered with ice and snow. The drive
wheels can spin even with these assistance
systems that can not always help to reduce
the risk of loss of vehicle cont rol.
{!) Tips
-ABS and ASR only work correct ly when a ll
four wheels are equipped w ith ident ica l
tires. Different tire sizes can lead to a reduc­
tion in engine power.
- You may hear noises when the systems de­
scribed are working.
ESC turns on automatically when you start the engine.

Braking
What affects broking efficiency?
New brake pads
During the first 250 miles (400 km), new brake
pads do not possess their full braking effect, they
have to be "broken in" first¢,&. . You can com­
pensate for this slightly reduced braking power
by pushing harder on the brake pedal. Avoid
heavy braking loads during the break-in period.
Operating conditions and driving habits
The brakes on today's automobiles are still sub­
ject to wear, depending largely on operating con­
ditions and driving habits~,&. . On vehicles that
are either driven most ly in stop-and -go city traf­
fic or are driven hard, the brake pads should be
checked by your authorized Audi dealer more of­
ten than specified in the
Warranty & Mainte­
nance booklet .
Failure to have your brake pads
i nspected can result in reduced brake perform­
ance .
On steep slopes, you should use the braking ef­
fect of the engine . This way, you prevent unnec­
essary wear on the brake system. If you must use
your brakes, do not hold the brakes down contin­
uously. Pump the brakes at intervals.

Operating noise
Noises may occur when braking depending on the
speed, braking force and outside conditions such
as temperature and humidity.
Effect of water and road salt
In certain situat ions, for example after driving
through water, in heavy ra in, after overn ight con­
densat ion or after washing your car, the braking
effect can be reduced by moisture or ice on the
brake rotors and brake pads. The brakes must be
dried first with a few carefu l brake applications.
At higher speeds and with the w indshie ld w ipers
turned on, the brake pads press against the brake
rotors for a short amount of time. This occurs at
regular intervals without the driver noticing and
provides for better brake response time under
wet conditions.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road
and the brakes are not used. Likewise, you clean
off accumulated salt coating from brake discs
and pads with a few cautious applications of the
brake ¢.& .
Corrosion
There may be a tendency for dirt to build up on
the brake pads and corros ion to form on the discs
if the car is not driven regularly or only for short
tr ips with little use of the brakes.
If the brakes are not used frequently, or if corro­
sion has formed on the discs, it is advisab le to
clean off the pads and discs by braking firmly a
few t imes from a moderately high speed¢.&.
Faults in the brake system
If you should notice a sudden increase in brake
pedal trave l, then one of the two brake circuits
may have failed
c:> .& .
Low brake fluid level
Malfunctions can occur in the brake system if the
brake fluid level is too low. The brake fluid leve l is
~ monitored e lectronically.

Brake lining wear status
Brake lining wear may be checked by visual in­
spect ion of the condition of the brake pads
through the openings in the wheel. If necessary,
the wheel may be removed for this inspection
c:> page 226, Replacing wheels.
_8 WARNING "'---
-New brake pads don't have the best stop­
pin g power and must be "broken-in" during
the initial 250 miles (400 kilometers). You
can compensate for this by press ing the
brake pedal more firmly. This also applies
later when new pads are installed.
-
- You shou ld perform braking maneuvers for
the purpose of cleaning the brake system
only if road conditions permit. Other road
users must not be put at r isk -you may
cause an acciden t!
- Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or
too often . This could cause the brakes to get
hot and diminish braking efficiency.
- Do not "ride the brakes" by resting your foot
on the pedal when you do not intend to
brake. This may cause the brakes to over­
heat, premature wear and increased stop­
p in g distance.
- Under certain cl imatic and operat ing condi­
tions such as passing through water, dr iv ing
in heavy rain or after washing the vehicle,
the effectiveness of the brakes can be re­
duced. In winter, ice can accumulate on the
b rak e pads, linings, discs and drums. Care­
fully apply brakes for a test. Brakes will dry
and ice coatings will be cleaned off after a
few careful brake applications.
- Driving for an extended period of time on
salt -covered roads wi thout using your
brakes can a lso affect braking efficiency .
