Front airbags
Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat occu
pants .
Fig. 165 Location of driver airbag : in steering whee l
Fig. 166 Location of front passenger's airbag: in the instru
ment panel
Your vehicle is equ ipped with an "Advanced Air
bag System" in compliance with Un ited States
Federal Motor Vehicle Safety Standard
(FMVSS) 208 as applicab le at the time your veh i
cle was manufactured. The safety belts for the
seats have "pretensioners" that help to take s lack
out of the belt system . The pretensioners are also
activated by the electronic control unit for the
airbag system .
The front safety belts a lso have load limiters to
help reduce the forces applied to the body in a
crash.
The airbag for the driver is in the steer ing wheel
hub ¢
fig. 165 and the airbag for the front pas
senger is in the instrument panel¢
fig. 166. The
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
i nformation 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 extremely important
for your safety and the safety of your passengers, especially infants and small children .
,&_ WARNING -
Never rely on airbags alone for protection.
- Even when they deploy, airbags provide only supp lemental p rotection.
- Airbag work most effectively when used with properly worn safety belts .
- Therefore, always wear your safety be lts and
make sure that everybody in your vehicle is
prope rly restrained.
,&_ WARNING
A person on the front passenger seat, espe
cially infants and small ch ild ren, will rece ive
serious i njur ies and can even be killed by be
ing too close to the airbag when it inf lates .
- Although the Advanced Airbag System in your vehicle is designed to turn off the front passenger airbag if an infant or a sma ll child
is on the front passenger seat, nobody can
absolutely guarantee that dep loyment un
der these special condit ions 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 "low risk" option under
the U .S. Federal Standard if a chi ld that is
heav ier than the typical one-year old child is
on the front passenger seat and the other
conditions for airbag deployment are met.
- Accident statistics have shown that ch ildren
are generally safer in the rear seat area than
in the front seating position .
- F or their own safety, all ch ildren, especially
12 years and younger, sho uld a lways ride in
the back properly restrained for their age
and size .

detail below . Because the front passenger seat
contains important parts of the Advanced Airbag
System, yo u must take care to prevent it from be
ing damaged. Damage to the seat may prevent
the Advanced Airbag for the front passenger seat
from do ing its job in a crash .
The front Ad vanced Airb ag S ystem con sis ts
of the following :
-Crash sensors in the front of the veh icle that
measure veh icle acceleration/deceleration to
provide information to the Advanced Airbag
System about the severity of the crash .
- An electronic control unit, with integrated
crash sensors for front and side impacts . The
control unit "decides" whether to fire the front
airbags based on the information received from
the crash sensors . T he control un it also "de
cides" whether the safety be lt pretensioners
sho uld be activated.
- An Advanced Airbag with gas generator and
control valve for the driver inside the steering
whee l hub.
- An Advanced Airbag with gas generator and
control valve inside the instrument panel for
t h e front passenger.
- A weig ht-sensing mat under the upholstery
padding of the front passenger seat cushion
that meas ures the tota l weight on the seat. The
information registered is sent cont in uous ly to
the e lectronic control unit to regulate dep loy
ment of the front Advanced Airbag on the pas
senger side.
- An airbag monitoring system and indicator
light in the instrument cluster
¢ page 162.
-A sensor in each front seat registers the dis
tance between the respect ive seat and the
steering wheel or instrument panel. The infor
mation registered is sent cont inuously to the
elect ron ic cont ro l unit to regulate deployment
of the front Advanced Airbags.
- T he
PASSENGER AIR BAG OFF light comes on
and stays on in the center of the i nstrument
pane l¢
page 162, fig . 168 and tells you when
the front Advanced Ai rbag on the passenger
side has been turned
off .
-A sensor below the safety belt la tch fo r the
front seat passenge r to measure the tension on
Airbag syste m
the sa fe ty belt. The tens ion on the safety be lt
and the weight registe red by the weight -sens
ing mat help the control unit "decide" whether
the front a irbag for the front passenger seat
should be turned
off or not¢ page 153, Child
restraints on the front seat- some important things to know.
- A sensor in the safety belt latch for the driver
and for the front seat passenger that senses
whether that safety belt is latched or not and
transm its this informat ion to the elect ro nic
cont ro l unit.
A WARNING
D amage to the fron t passenger seat can pre
vent the fron t air bag from working prope rly.
- Imp roper repai r or d isassembly of the front
passenger and driver sea t will prevent the
Advanced Airbag System from functioning properly .
- Repairs to the front passenge r seat must be
performed by qualified and p roperly trained
workshop personne l.
- Never remove the front passenger or driver seat from the vehicle .
- Never remove the upho lstery from the front
passenger seat.
- Never d isassemble o r remove par ts from the
seat or disconnect w ires from it.
- Never carry sh arp objects in yo ur po ckets or
p la ce them on t he seat.
If the weight-sens
ing mat in the passenger seat is punctu red
it cannot work properly .
- Never carry things on yo ur lap or carry ob
jects on the passenger seat. S uch items can
increase the we ight registe red by the
weight-sensing mat and send the wrong in
formation to the a irbag control unit.
- Never store items under the front passenger
seat . Parts of the Advanced Airbag System
under the passenger seat could be dam
aged, p reventing them and the airbag sys
tem from wo rking prope rly.
- Never p lace seat covers or rep lacement up
holstery that have not been specifically ap
p roved by Aud i on the front seats.
- Seat covers can prevent the Advanced Air bag System from recognizing child

-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 yourself. These obje cts
could cause injury in a crash, e specially
when the airbags inflate.
- Never recline the front passenger's seat to
transport objec ts . Items can also move into
t h e area of the side airbag or the front air
bag dur ing braking or in a sudden maneu·
ver. Objects near the airbags can become
projectiles and cause injury, part icularly
when the seat is reclined.
A WARNING
The f ine dust created when a irbags dep loy can
cause breathing problems for people with a
history of asthma or other breathing condi
tions .
- To reduce the r isk of breathing problems,
those w ith asthma or other resp iratory con
ditions should g et fr esh air r ight away by
get ting out of the vehicle o r opening w in
dows or door s.
- If you are in a col lision in w hich a irbags de
p loy, wash your hand s and fa ce wi th mild
soap and water before eating.
- Be caref ul not to get the dus t into you r eyes,
or into any cuts or s cratches.
- If the residue should get into you r eyes,
flush them with water.
Monitoring the
Advanced Airbag System
Airbag monitoring indicator light
Two separa te indicators monitor the function of
the Advanced Airbag System: the airbag moni
toring indicator light and the
PASSENGER AIR

-does not come on when the ignition is sw itched
on,
- does not go out a few seconds after you have
switched on t he ignit ion, or
- comes on wh ile driving.
If an airbag system malfunction is detected, t he
i ndic ator light will fi rst s tart flashing to catch the
dr iver's at ten tion and the n st ay on con tinuo usly
to serve as a constant reminder to have the sys
tem inspected immediately .
If a malfu nction occurs that turns the front air
bag on the passenge r side off, the
PASSENGER

Repair, care and disposal of the airbags
Parts of the airbag system are installed at many
different places on your Audi. Installing, remov ing , servicing or repairing a part in an area of the
vehicle can damage a part of an airbag system and prevent that system from working properly in a collision.
There are some important things you have to know to make sure that the effectiveness of the
system will not be impaired and that discarded
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 airbag cover or the in
strument panel or modify them in any way .
- Never attach any objects such as cup holders
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. Solvents or cleaners could damage the airbag cover or change
the stiffness or strength of the material so
that the airbag cannot deploy and protect
properly.
- Never repair, adjust, or change any parts of
the airbag system.
- All work on the steering wheel, instrument
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
Airbag system
who has the training and special equipment
necessary.
- For any work on the airbag system, we
strongly recommend that you 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 without interference:
- Never install seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
Audi .
- Never use additional seat cushions that
cover the areas where the side airbags in
flate.
- Damage to the original seat covers or to
the seam in the area of the side airbag
module must always be repaired immedi
ately 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 replacement
parts designed and approved especially for
your Audi model version. Replacement of complete airbag systems or airbag components must be performed by qualified work
shops only. Make sure that any airbag serv
ice action is entered in your 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 pyrotechnic
circuit interrupter .
- Work on the pyrotechnic circuit interrupt
er must only be performed by a qualified
dealer -risk of an accident!
- If the vehicle or the circuit interrupter is
scrapped, all applicable safety precautions
must be followed.

exceptional circumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rear-facing child safety seat in a rear
seating position and have the airbag system
inspected immediately by your Audi dealer .
A 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
reduce the risk of injury through interaction with
Child safety
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 con
trol unit of the Advanced Airbag System. When a

Electronic Stabilization
Control (ESC)
Description
The Electronic Stabilization Control (ESC) reinfor
ces driver safety. It reduces the risk of slipping
and improves driving stability. ESC detects criti
cal s ituations such as the vehicle oversteering
and understeering or the wheels sp inning. The
veh icle is stab ilized by applying the brakes or re
ducing engine torque. Once the ESC is act ive, the
indicator light
m blinks in the instrument clus
ter.
The fol low ing systems a re integrated in the ESC:
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up when
brak ing . The vehicle can still be steered even dur
ing hard braking. Apply steady pressure to the
brake pedal. Do not pump the pedal. A pulsing in
the brake pedal indicates that the system is help
ing you to brake the vehicle.
Brake assist system
The brake assist system can decrease braking d is
tance . It increases braking power when the dr iver
presses the brake pedal quick ly in emergency s it
uations. You must press and hold the brake pedal
unti l the situation is over. In vehicles w ith adap
tive cruise control*, the brake assist system is
more sensitive if the distance detected to the ve
hicle ahead is too small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive whee ls
begin to spin and adapts the force to the road
conditions. This makes it easier to start, acceler
ate and drive up hills.
Smart Technology
Electronic differential lock (EDL)
The EDL brakes whee ls that are spinning and
trans fers the drive power to the other whee ls.
This function is not avai lable at higher speeds .
In extreme cases, EDL automatically sw itches off
to help keep the brake on the braked wheel from
overheating. EDL will switch on again automati
ca lly when conditions have returned to normal.
Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque.
On vehicles with dynam ic steering*, ESC helps
stab ilize the steer ing in crit ical situat ions .
Selective wheel torque control
Selective wheel torque control is used when driv
ing on curves. The front wheel on the inside of
the curve or both wheels on the inside of the
curve are braked select ively as needed. This al
lows more precise driving in curves. The applica
ble system may not activate when driving in wet
o r snowy conditions .
A WARNING
-
-The ESC and its integrated systems cannot
overcome the laws of physics. This is espe
cially important on slippery or wet roads. If
the systems begin acting to stabilize your
vehicle, you should immediately change
your speed to match the road and traffic conditions . Do not let the increased safety
provided by these systems tempt you to
take risks. Doing 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 los ing con
trol of the vehicle increases when driving
too fast, especially through curves and on
slippery or wet roads, and when driving too
close to vehicles up ahead . The ESC and its
integrated systems cannot a lways prevent
coll isions - there is st ill a risk of acc idents!
- Always accelerate with special care on even,
smooth surfaces such as those that are wet
or covered with ice and snow. The drive

wheels can spin even with these assistance
systems that cannot always help to reduce
the risk of loss of vehicle control.
@ Tips
-ABS and ASR only work correctly when all
four whee ls are equipped with identical
Switching on/off
tires . Different tire sizes can lead to a reduc
tion in engine power .
- You may hear noises when the systems de
scribed are working.
- When installing a factory-supplied roof rack
system on the roof railing, the ESC will
adapt itself to a different center of gravity.
ESC turns on automatically when you start the engine.

Braking
What affects broking efficiency?
New brake p ad s
During the first 250 miles (400 km), new brake
pads do not possess their full braking effect, they
have to be "broken in" first¢ &. .,,.
193
Page 196 of 302

Smart Technolog y
Operating c ondit ion s and drivin g hab it s
The brakes on today 's automobi les are st ill sub
ject to wear, depending largely on operating con ditions and driving habits¢.&. . On vehicles that
are either driven mostly in stop-and-go city traf
f ic or are driven hard, the brake pads should be
checked by your authori zed Audi dealer more of
ten than specified in the
Wa rra nty & Mainte
n an ce boo kle t .
Fa ilure to have your brake pads
inspected can result in reduced brake perform
ance.
On steep slopes, you should use the brak ing ef
fect of the eng ine . Th is way, you prevent unnec
essary wear on the brake system. If you must use
your brakes, do not ho ld the brakes down contin
uously. Pump the brakes at inte rva ls.
Operat ing no ise
Noises may occur when braking depending on the
speed, brak ing force and outside conditions such
as temperature and humid ity .
Effect of w ate r an d r oad sal t
In certain situations, for example after driving
through water, in heavy rain, after overn ight con
densat ion or after washing your car, the braking
effect can be reduced by mo isture or ice on the
brake rotors and brake pads . The brakes must be
d ried first with a few carefu l brake applications.
At h igher speeds and with the w indshield wipers
turned on, the brake pads press against the brake rotors for a short amount of t ime . This occurs at
regular intervals without the d river noticing and
p rov ides for better brake response t ime unde r
wet conditions .
The effectiveness of the brakes can be reduced
when the vehicle is dr iven on a salt-covered road
a nd the brakes are not used . L ikew ise, you clean
off accumulated sa lt coating from brake discs
and pads with a few cautious applications of the brake ¢.&. .
Corros ion
There may be a tendency for dirt to bui ld up on
the brake pads and corros ion to fo rm on the discs
if the car is not driven regularly or on ly for short
trips with litt le use of the brakes.
194
If the brakes are not used frequently, or if corro
sion has formed on the discs, it is advisable to clean off the pads and d iscs by braking firmly a
few times from a moderate ly high speed¢.&. .
Fault s in the brak e system
If you shou ld notice a sudden increase in bra ke
pedal travel, then one of the two brake circuits
may have failed
¢ .&. .
Lo w b rake fluid l evel
Malfunctions can occur in the brake system if the
brake flu id leve l is too low. The brake fl uid level is
monitored electronica lly.
Brake boos ter
The brake booster increases the pressure that you
generate w ith the brake pedal. It on ly operates
whi le the engine is runn ing o r with the ig nit ion
switched on (hybrid drive*)
¢ ,& .
Brake lining we ar status
Brake lining wear may be checked by visual in
spection of the condition of the brake pads
through the open ings in the wheel. If necessary ,
the wheel may be removed for this inspec tion
¢ page 260, Replacing wheels .
& WARNING -
- New brake pads don't have the best stop
ping power and m ust be "broken-in" during
the initial 250 miles (400 km) . You can com
pensate for this by pressing the brake pedal
more f irm ly. This also applies later when
new pads are installed.
- You should 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 accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gea r or lower dr iving range. Do not ride the
bra kes or ho ld the peda l down too long or
too often . This could cause the bra kes to get
