More important things to know about
front airbags
F ig. 2 11 Inflated front airbags
Safety belts are important to help keep front
seat occupants in the proper seated pos ition
so that airbags can unfo ld properly and pro ­
vide supplemental protection in a fronta l col­
l ision.
A irba g sy stem 193
The front airbags are designed to provide ad ­
ditional protection for the chest and face of
the driver and the front seat passenger when:
- safety belts are worn properly
- t he seats have bee n positioned so that the
occ upan t is properly seated as far as poss i­
b le from the airbag
- and the head restraints have been properly
adj usted
Because airbags inflate in the blink of an eye
with great force, t hings you have on your lap
or have placed on the seat co uld become dan­
gerous projecti les, and be p ushed in to you if
the a irbag inf lates.
When an airbag deploys, fine dust is re leased.
T his is no rma l and is not caused by a fi re in
the vehi cle. This dust is made up mos tly of a
powder used to lub ricate the airbags as they
deploy. It could irritate skin.
It is important to remembe r that wh ile the
s u pplementa l airbag system is designed to re­
duce the like lihood o f serious injuries, other
injuries, for example swelling, bruising and
minor abrasions, can a lso happen when air ­
bags inflate . A irbags do not protect the arms
or the lower parts of the body. Front airbags
supplement the th ree-point safety belts only
i n some frontal co llisions in which the vehicle
deceleration is high enough to deploy the air­
bags.
Front a irbags will not deploy :
-if the ignition is sw itched off when a crash
occurs
- in side collisions
- in rear-end co llisions
- in rollovers
- when the crash dece leration meas ured by
the air bag system is less than the minimum
threshold needed for airbag deployment as
reg istered by the electronic cont ro l unit
The front passenger airbag also will not
deploy:
- when the front passenger seat is not occu-
pied ..,.

194 Airbag sys te m
- when the weight on the front passenger
seat as sensed by the Advanced Airbag Sys­
tem indicates that the front airbag on the
passenger side has to be turned off by the
electron ic control unit (the
PA SSEN GER AIR
BAG OFF
light comes on and stays on)
A WARNING
Sitting in the wrong position can increase
the risk of serious injury in crashes.
- To reduce the r isk of injury when the air­
bags inflate, the driver and passengers
must always sit in an upright position,
must not lean against o r place any pa rt
of the ir body too close to the area where
the airbags are located .
- Occ upants who are unbelted, out of posi­
t ion or too close to the airbag can be se­
riously injured by an airbag as it unfolds
with great force in the blink of an eye
¢page 186.
A WARNING -
A child in a rearward-facing child safety
seat installed on the front passenger seat
w ill be seriously injured and can be k illed if
the front a irbag inflates -even with an Ad­
vanced Airbag System.
- The inflating a irbag will hit the child
safety seat or infant carrier with great
force and w ill smash the ch ild safety seat
and child against the backrest, center
armres t, door or roof.
- Always install rear-facing child safety
seats on the rear seat.
- If you must install a rearward-fac ing
child safety seat on the front passenger
seat because of excep tional circ umstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im­
mediately install the rear-facing child
safety seat in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer.
A WARNING
Objects between you and the airbag will
i nc rease the r isk of injury in a crash by in­
terfering with the way the airbag unfolds
or by be ing pushed into you as the airbag
i n flates.
- Never hold things in yo ur hands or on
your lap when the veh icle is in use.
- Never transpo rt items on or in the area
of the front passenger seat. Objects
could move into the a rea of the front air­
b ags du ring bra king or other sudden ma­
neuvers and become dangero us projec­
tiles that can cause serious personal in­
jury if the ai rbags inflate.
- Never p lace or attach accessories or oth­
er objects (such as cupholde rs, tele­
phone brackets, large, heavy or bulky ob­
jects) on the doors, ove r or near the area
marked "AIRBAG" on the steer ing whee l,
instrument panel , seat backrests or be­
tween those areas and yourself . These
objects could ca use in jury in a c rash, es­
pecially when the airbags infla te.
- Never recline the front passenger 's seat
to transpo rt objects . Items can a lso
move into the a rea of the s ide airbag or
the front airb ag d uring bra king or in a
sudden maneuve r. Objects nea r the air­
bags can become projectiles and cause
in ju ry, partic ularly when the seat is re­
clined.
- Never tilt the front passenger seat back­
rest forward when the vehicle is moving .
An inflating a irbag w ill force the back­
rest backward and can injure rear seat oc­
cupants.
A WARNING
The fine dust created when airbags deploy
can cause breathing prob lems for people
with a history of asthma or other breath­ i ng cond itions.

away by getting out of the vehicle or
opening windows or doors.
-If you are in a collision in which airbags
deploy, wash your hands and face with
mild soap and water before eating.
- Be careful not to get the dust into you r
eyes, or into any cuts or scratches.
- If the residue should get into your eyes,
flush them with water.

Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different places on your Audi . Installing,
removing, 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 p roperly 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 dis­
carded components do not cause injury or pol­
lute the environment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an airbag from deploying when needed or deploying
an airbag unexpectedly:
- Never cover, obstruct, or change the steering wheel horn pad or airbag cover
or the instrument panel or modify them
in any way .
- Never attach any objects such as cu­
pholders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners could damage the airbag cover
or change the stiffness or strength of the material so that the airbag cannot de­
ploy and protect properly.
- Never repair , adjust, or change any parts
of the airbag system.
- All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including the installation of audio
equipment, cellular telephones and CB radios, etc.) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work­
shop.
- Never modify the front bumper or parts
of the vehicle body.
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer. - The airbag system can be activated only
once. After an airbag has inflated, it
must be replaced by an authorized Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only once . After an airbag has been deployed,
it must be replaced with new replace­
ment parts designed and approved espe­
cially for your Audi model version . Re­
placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only. Make sure that any airbag service action
is entered in your Audi Warranty
& Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD .
-For safety reasons in severe accidents,
the alternator and starter are separated
from the vehicle battery with a pyrotech­
nic circuit interrupter.
- Work on the pyrotechnic circuit inter­
rupter must only be performed by a
qualified dealer - risk of an accident!

200 Airbag system
The side airbags are located in the sides of the
front seat backrests ¢
fig. 213 and the rear
backrest* facing the doors. They are ident ified
by the word "AIRBAG".
The side airbag system basically consists of:
-the e lectronic control module and external
side impact sensors
- the two side airbags located in the sides of
the front backrests
- two rear side airbags (as an ordered
option)
-the a irbag warn ing light in the instrument
cluster .
The airbag system is monitored electron ically
to make certain that it is functioning properly
at all times. Each time you turn on the igni­
tion, the airbag system indicator light will
come on for a few seconds (self diagnostics) .
The s ide airbag system supplements the safe­
ty belts and can help to reduce the risk of in­
jury to the driver's, front and rear* passeng­
er's upper torso on the side of the veh icle that
i s struck in a side collision . Th e airbag deploys
on ly in side impacts and only when the veh icle
acceleration registered by the control unit is
high enough . If this rate is below the refer­
ence value programmed into the control unit,
the side airbags will not be triggered, even
though the car may be badly damaged as a re­
sult of the collision. It is not possible to de­
f in e an a irbag tr igger ing range that will cover
every possible angle of impact, since the cir­
cumstances will vary considerably between
one collision and another. Important factors
include, for examp le, the nature (hard or soft)
of the impacting object, the angle of impact ,
vehicle speed, etc . ¢
page 201, Important
safety instructions on the side airbag system .
Aside from their normal safety function , safe­
ty belts work to help keep the driver or front
passenger in position in the event of a side
coll ision so that th e side airbags can provide
protection.
The airbag system is
not a substitute for your
safety be lt. Rather, it is part of the overall oc ­
cupant restraint system in your vehicle . Al­
ways remember that the side airbag system can
only help to protect you if you are wearing
your safety belt and wearing it properly. This
is another reason why you should a lways wear
your safety belts, not just because the law re­
quires you to do so¢
page 175, General
notes .
It is important to remember that wh ile the
s u pplementa l side airbag system is designed
to reduce the likelihood of serious injuries,
other injur ies, for example, swelling, bru is in g,
and minor abrasions can also be assoc iated
with deployed side airbags . Remember too,
s ide airbags will dep loy only once and only in
certain kinds of accidents - your safety belts
are always there to offer protection.
Vehicle damage , repair costs or even the lack
of vehicl e damage are not necessarily an indi­
cation of over-sensitive or failed airbag activa­
t ion. In some coll is ions, both front and side
airbags may inflate . Remember too, that air ­
bags will deploy only once and only in certain
k inds of co llisions -yo ur safety belts are al­
ways there to offer protection in those acc i­
den ts in which airbags are no t supposed to
deploy or when they have already deployed .
The side airbag system will not deploy:
-when the ignition is t urned off
- in side collisions when the acceleration
measured by the sensor is too low
- in front -end collisions
- in rea r-end collisions
- in rollovers .
In some types of accidents the front airbags ,
s ide curtain airbags and s ide a irbags may be
triggered together .
A WARNING
-
-Safety belts and the airbag system will
only provide protection when occupants
ar e in the proper seating position
¢page 201.
- If the airbag indicator light comes on
when the vehicle is being used, have the
system inspected immediately by your
authorized Audi dealer. The airbag may

inflates in side impacts and only when the ve­
hicle acceleration registered by the control
un it is high enough. If this rate is below the
reference value programmed into the contro l
unit, the side airbags will not be triggered,
even though the car may be badly damaged as
a result of the coll ision.
It is not possible to
define an airbag triggering range that will
cover eve ry possible angle of impact, since the
circumstances w ill vary considerably be tween
one co llision and another . Important factors
include, for examp le, the natu re (hard or soft)
of the impacting object, the angle of impact,
veh icle speed, etc. c::>

system inspected immediately by your
authorized A udi dealer . The side curtain
airbag may not work properly even when
the vehicle acce lerat ion in a side collision
is high enough to activate the airbag.
How side curtain airbags work
Side curtain airbags con work together with
side airbags to help reduce the risk of head
and upper torso injuries for occupants who
ore properly restrained.

The side curtain airbags inflate between 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
same kind of child restraint offered by child restra int manufacturers.
The weight ranges for the individual types, makes and mode ls of ch ild restra ints that the
NHTSA has specified in the Safety Standard
together with the we ight ranges of typical in­
fants and typical 1 year -old child have been
stored in the control unit of the Advanced A ir­
bag System . When a chi ld restraint is being
used on the front passenge r seat with a typi­
cal 1 year -old ch ild, the Advanced Airbag Sys­
tem compares the we ight measured by the
weight sensing mat with the information stor­
ed in the electronic control unit.
The electron ic contro l unit al so registers the
tension on the front passenger safety be lt.
The tension on the safety be lt for the front
passenger seat will be different for an adult
who is properly using the safety belt as com­
pared to the tension on the be lt when it is
used to attach a child restraint to the seat.
T he sensor below the latch for the safety belt
for the front seat passenger measures the
tension on the belt . T he input from this sen­
sor is t hen used w ith the we ight to "decide",
whether there is a ch ild restraint with a typ ica l
1 year-o ld child on the front passenger seat
and whether or not the airbag must be turned
off .
Child restraints and Advanced Airbags
Regard less of the child restraint that you use,
make sure that it has been certified to meet
United States Federal Motor Vehicle Safety
Standards and has been certified by its manu­
facturer for use with an airbag . Always be sure
that the chi ld restraint is p roperly instal led at
one of the rear seat ing pos itions . If in excep­
tional ci rcumstances you must use it on the
front passenger seat, carefu lly read all of the
information on child safety and Advanced Air­
bags and heed a ll of the app licable WARN­
INGS. Make certain that the child restraint is
correctly recognized by the weight-sensing
Child Sa fet y 207
mat inside the front passenger seat, that the
front passenger airbag is turned off and that
the a irbag status is always correct ly signaled
by the
PAS SENGE R AIR BAG OFF light.
Many types and models of child restraints
have been available over t he years, new mod­
els are introduced regu larly incorporating new
and improved des igns and o lder models are
taken out of product ion. Ch ild restraints are
not standard ized . Child restraints of the same
type typ ically have d ifferent weights and sizes
and different 'footpr ints,' the size and shape
of the bottom of the ch ild restrai nt that sits
o n the seat, when they a re insta lled on a veh i­
cle seat. These diffe rences make it v irtually
impossible to certify compliance with the re­
quirements for advanced airbags with each
and every ch ild restraint that has ever been
sold in the past or will be sold over the course
of the useful life of your veh icle.
For this reason, the United States National
Highway Traffic Safety Adm inistrat ion has
published a list of spec ific type, makes and
models of child restraints that must be used
to certify comp liance of the Advanced Airbag
System in your veh icle with the suppression

low ing except ional situations when slip or a
h ighly effective differential locking function is
des irable . Examp les:
- when driving with tire chains,
- when driving in deep snow or on loose
ground,
- when driving on uneven surfaces with the
whee ls severe ly unloaded (articulation), and
- when rocking the vehicle loose after it has
become stuck . When the
unusual situation is past, you
sho uld shift back to the norma l ESC operating
mode by pushing the button again . The mes­
sage
S ta b ilizat ion cont rol (ES C): O n then ap­

H ill desc ent control
The hill descent control is switched on in ESC
offroad mode . When slowly descending steep
gradients on loose ground or when the axles
are articulated, hill descent control provides ass istance by automatically apply ing the
brakes to keep vehicle speed constant. The ve ­
hicle is also rendered easier to steer by selec­
t ive d istr ibut ion of braking force. Hill descent
control intervenes when:
- the acce lerator pedal is not pressed,
- the vehicle is travelling less than 12 mph
(20 km/h),
- a steep gradient is detected,
- wheel behavior indicates loose ground or
conditions with poor adhesion (e .g. also axle
art iculation).
Hill descent contro l operates both d riving for­
ward and in reverse. Active hill descent con­
tro l is deactivated by pressing the accelerator
pedal until the condit ions for activation al­
ready listed are met again .
A WARNING
--
- The Electronic Stabilization Contro l is
neverthe less s ubject to the laws of phys­
ics. It is part icularly important to pay at­
tention to this fact on wet and slippe ry
roads . It i s therefore important that you
always adapt your dr iving to the cond i­
tion of the road and traffic conditions . Do
not a llow the increased safety provided
by the E lectronic Stabilization Contro l
system to lull you into accepting addi­
tional safety risks .
- Please be aware that in ESC offroad
mode, particularly on a smooth and s lip­
pe ry road, the wheels may have an in­
creased tendency to sp in and the vehicle
may b reak away - dange r of skidding!

8_ WARNING
Although the ABS is very effective, always
remember that bra king capability is limit­
ed by t ire traction . Always adjust your dr iv­
ing spee d according to the road and t raffic
co nditions. Do no t let t he extra sa fety af­
forded by the ABS tempt you into ta king
extra risks. The ABS cannot overcome the
laws of physics.
@ Tips
- If ABS is not functioning prope rly, a
warning light will come on. See
¢page 18 .
-If a fault occurs in the ABS, the EDL is al­
so not functioning. This is indicated by
the ABS warning light .
Brake assistant
The brake assistant is designed to achieve the
optimum braking effect .
The brake assistant helps to increase the ef­
fective b rak ing power and thus to achieve a
shorter stopp ing distance. If the driver
presses the brake pedal very quickly, the brake
assistant automatica lly boosts the braking
force to the maximum level, up to the point where the anti-lock brake function (ABS) inter­
venes to stop the wheels from locking. You
should then keep the brake pedal pressed un­
til the veh icle has braked to the required
speed . The brake assistant sw itches itself off
as soo n as you re lease the brake pedal.
Automatic full braking a ssist
This funct ion allows full brak ing in spite of
h igh brake pedal forces (e .g . when the brakes
a re severely stressed because the vehicle is
fully loaded) . The driver notices th is function
throug h a reduction of pedal force and in­
creased pedal trave l. When the brake peda l is
r e leased, fu ll braking assis t switc hes off again
automatically.
I f the re is an ABS fa il ur e, the brake ass ista nt
and automatic full b rak ing ass ist are not avai l­
ab le . The brake assistant wi
ll not be operative if
there is a ma lfunction in the ABS .
8_ WARNING
-Please remember that the accident risk a l-
ways increases if you drive too fast, espe­
cially in corners or on a slippery road, or if
you follow the veh icle ahead of you too
closely. Increased r isk of an accident can­
not be compensated for even by the brake
assistant, so always maintain a safe speed.
Servotronic ® -
advanced power
steering system
The power steering systems uses the power of
the running engine to allow precise steering
with little effort.
The advanced Servotronic ® power steering
system senses the road speed and electron i­
cally adjusts power assistance to provide com­
fortab le and safe steering response exact ly
matched to the vehicle speed .
Power steer ing will not work if the engine is
off . As a result, the steering wheel will be hard
to turn .
The power steering fluid level is checked dur­
ing the scheduled maintenance services .
d) Note
If there is an electronic malfunction, ser­
votronic
will still function like a conven­
tiona l powe r steering system, providing a
constant steering support force that is no
l onger proportionate to the vehicle speed .
This is most not iceable when turning the
stee ring wheel at low speeds (fo r example
when pa rking), - more effort w ill be re­
q uired than us ua l.
- Be aware o f the different than usual
steering response and adjust your steer ­
ing force accordingly.
- Have the problem checked and set r ight
by an Audi dealer as soon as possible .
