108 Safety belts
Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for
people riding in vehicles .
Fig. 111 Unbe lted occupa nts in a ve hicle heading for a
wall
Fig . 11 2 The ve hicle c ras hes into t he wa ll.
The physical principles are simp le. Both the
vehicle and the passengers possess energy
which varies w ith veh icle speed and body
weight . Engineers call th is energy ''kinetic en
ergy ."
The higher the speed of the vehicle and the
greater the vehicle's weight, the more energy
that has to be "absorbed" in the crash .
Vehicle speed is the most significant factor . If
the speed doub les from 15 to 30 mph (25 to
50 km/h) , the energy increases 4 t imes!
Because the occupants in this vehicle are not
using safety belts ¢
fig. 111, they will keep
mov ing at the same speed the vehicle was
mov ing just before the crash, unti l something
stops them -here, the wall¢
fig. 112 .
The same pr inc iples apply to people sitting in
a vehicle that is involved in a frontal collision .
Even at city speeds of 20 to 30 mph (30 to 50
km/h), the forces act ing on the body can reach one ton (2,000 lbs, or 1
,000 kg) or
more. At h igher speeds, these forces are even
greater.
Peop le who do not use sa fety belts are also
not a ttached to their vehicle. In a frontal colli
sion they wi ll also keep moving forward at t he
speed their vehicle was travell ing just before
the crash. Of course, the laws of physics don't
just app ly to frontal collisions, they determine
what happens in all kinds of acc idents and col
lis ions .
What happens to occupants not wearing
safety belts?
In crashes unbelted occupants cannot stop
themselves from flying forward and being in
jured or killed . Always wear your safe ty belts!
Fig . 11 3 A driver not wea ring a safety belt is vio le n tl y
t hrown forward
Unbelted occ upants a re not able to resist the
tremendous forces of impact by hold ing tight
or bracing themse lves. Without the benefit of
safety restra int systems, the unrestrained oc
cupant will slam violently into the steering
wheel, instr ument panel, w indshield, or what
ever else is in the way ¢ fig. 113. This impact
with the veh icle i nte rior has all the energy
t h ey had j ust before the c rash.
Never rely on airbags alone for protection .
Even when they deploy, a irbags provide only
additional prote ction . Airbags a re not sup
posed to deploy in all k inds of accidents. Al
t h ough your Aud i is equipped wi th airbags, all
vehicle occupants, i ncluding the driver, must
wear safety be lts cor rectly in o rder to m ini
mize the risk of severe in jury or death in a
crash .
Page 111 of 260
Remember too, that airbags will deploy only
once and that your safety belts are always
there to
offer protection in those accidents in
which airbags are not supposed to deploy or
when they have already deployed . Unbelted
occupants can also be thrown out of the vehi
cle where
even more severe or fatal injuries
can occur .
Safety belts protect
People think it's possible to use the hands to
brace the body in a minor collision . It 's simply
not true!
Fig . 114 Driver is properly restrained in a sudden b rak
i ng ma neuve r.
Safety belts used properly can make a big dif
ference . Safety belts help to keep passengers
in their seats, gradually reduce energy levels
applied to the body in an accident, and help
prevent the uncontrolled movement that can
cause serious injuries. In addition, safety belts
reduce the danger of being thrown out of the
vehicle.
Safety belts attach passengers to the car and
give them the benefit of being slowed down more gently or "softly" through the "give" in
the safety belts, crush zones and other safety
features engineered into today's vehicles . By
"absorbing" the kinetic energy
over a longer
period of time, the safety belts make the
forces on the body more "tolerable " and less
likely to cause injury.
Although these examples are based on a fron
tal collision, safety belts can also substantial ly reduce the risk of injury in other kinds of
crashes. So, whether you're on a long trip or
just going to the corner store, always buckle
Safety belts 109
up and make sure others do, too. Accident sta
tistics show that vehicle occupants properly
wearing safety belts have a lower risk of being
injured and a much better chance of surviving
an accident. Properly using safety belts also
greatly increases the ability of the supplemen
tal airbags to do the ir job in a collision . For
this reason, wearing a safety belt is legally re
quired in most countries including much of
the United States and Canada.
Although your Audi is equipped with a irbags,
you still have to wear the safety belts provid
ed . Front airbags, for example, are activated
only in some frontal collisions. The front air
bags are not activated in all frontal collisions,
in side and rear collisions, in roll overs or in
cases where there is not enough deceleration
through impact to the front of the vehicle.
The same goes for the other airbag systems in
your Audi . So, always wear your safety belt
and make sure everybody in your vehicle is
properly restrained!
Important safety instructions about
safety belts
Safety belts must always be properly posi
tioned across the strongest bones of your
body .
"' Always wear safety belts as illustrated and
described in th is chapter.
"'Make sure that your safety belts are always
ready for use and are not damaged.
A WARNING ~
Not wearing safety belts or wearing them
improperly increases the risk of serious
personal injury and death. Safety belts can
work only when used correctly.
- Always fasten your safety belts correctly
before driving
off and make sure all pas
sengers are properly restrained.
- For maximum protection, safety belts must always be positioned correctly on
the body .

Front airbags
Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat
occupants .
Fig. 119 Lo cation of dri ver airbag: in steering whee l
Fig. 120 Loca tion of front passe nger's ai rb ag : in the in
strument panel
Your vehicle is equipped with an "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 safety belts
for the front seats have "pretensioners" that
help to take slack out of the belt system. The
pretensioners are also activated by the elec
tronic control unit for the airbag system.
The front safety belts also 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. 119 and the airbag for the
front passenger is in the instrument panel
¢
fig. 120. The general location of the airbags
is marked "AIRBAG".
There is a lot you need to know about the air
bags in your vehicle . We urge you to read the
Airbag system 119
detailed information about airbags, safety
b elts 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 in
fants and small children.
A WARNING ,.;;
Never rely on airbags alone for protection .
- Even when they deploy, airbags provide
only supplementa l protect ion.
- Airbag work most effectively when used
with properly worn safety belts.
- Therefore, always wear your safety belts
and make sure that everybody in your ve
hicle is properly restrained.
A WARNING
A person on the front passenger seat, es
pecially infants and small children, will re
ceive serious injuries and can even be kil
led by being too close to the airbag when
it inflates .
- Altho ugh 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 under these special
conditions is imposs ible in all conceiva
ble situations that may happen during
the useful life of your vehicle .
- The Advanced Airbag System can deploy
in accordance with the "low risk" option
under the U .S. Federal Standard if a child
that is heavie r than the typical one-year
old child is on the front passenger seat
and the other conditions for airbag de
ployment are met .
- Accident statistics have shown that chil
dren are generally safer in the rear seat
area than in the front seating position.
- For its own safety, a child should always
ride properly restrained for its age and
size.
-
Page 123 of 260
The front airbag on the passenger side may
not dep loy (the PA SSENGER AIR BAG OFF
light does not illuminate and stay lit) if:
- a small adu lt or teenager is on the fron t pas
senger seat
- a passenger who is not sitt ing upright w ith
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 .
I f the front passenger airbag deploys, the
F ederal Standard requires the a irbag to meet
the " low risk" deployment criteria to help re
duce the risk of injury through interaction
with the airbag. "Low risk" deployment occurs in those crashes that take place at lower de
celerations as defined in the electronic co ntrol
un it
o page 125 .
Alway s rem ember : Please be sure to read the
important information in the sections that
follow and be sure to heed all of the WARN
INGS.
8, WARNING
To reduce the risk of injury when an airbag
inflates, a lways wear safety belts prope rly.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, your risk of injury is much higher.
- You w ill also receive serio us injuries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in
fla tes - even with an Advanced Airbag
opage 115 .
A WARNING ,~
A child in a rearward -facing child sa fety
seat insta lled on the front passenger seat
wi ll be seriously injured and can be ki lled if
the front a irbag inflates - even with an Ad
vanced Airbag System.
- Although the Advanced Airbag System in
yo ur vehicle is designed to turn
off the
front a irbag when a rearward-fac ing
child restraint has been installed on the
front passenger seat, nobody can abso lute ly guarantee that deployment is im-

possible in all conceivable situations that
may happen dur ing the usefu l life of your
veh icle.
- The inflating airbag will h it the ch ild
safety seat or infant carrier with great
force and will smash the child safety seat and child against the backrest, door, or roof.
- If you must install a rearward fac ing

media tely ins ta ll the rear-fac ing ch ild
safety seat in a rear seating position and
have the airbag system inspected by your
Aud i dea le r.
A WARNING
If, in except iona l circumstances, you must
install a forward-facing child restraint on
the front passenger's seat:
- Always make sure the forward-facing seat has been designed and certified
by
its manufacturer fo r use on a front seat
wit h a passenger front and s ide a irbag.
- Never put the forward-facing child re
straint up against or very near the instru
ment panel.
- Always move the passenger seat into its
rearmost pos ition in the seat's fore and
aft ad justment range, as fa r away from
the airbag as possible, before install ing
the forwa rd-fa cing ch ild restra int. The
bac krest mus t be adju sted to a n up right
posi tion.
- Ma ke su re that the

Advanced Airbag System components
T he front passenger seat in yo ur vehicle has a
lot of very important parts of the Advanced

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.
Airbag system 129
-Work on the pyrotechnic circuit inter
rupter must only be performed by a
qualified dealer - risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre
cautions must be followed.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys
tem performs in a crash. For example, using
tire-rim combinations not approved by Audi,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen
sion struts, shock absorbers etc. can change
the forces that are measu red by the airbag
sensors and sent to the electronic control unit. Some suspension changes can, for exam
ple, increase the force levels measured by the
sensors and make the airbag system deploy in
crashes in which it would not deploy if the
changes had not been made. Other kinds of
changes may reduce the force levels meas
ured by the sensors and prevent the airbag
from deploying when it should .
The sensors in the safety belt buckle for the
driver and front passenger seat tell the elec
tronic control module if the safety belt is
latched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high-
er rate of vehicle deceleration than if the safe-
ty belt is not being used . Therefore, in a par
ticular collision, it is possible that an airbag
will not deploy at a seating position where the
safety belt is being used but will inflate at the
position where the safety belt is not being
used.
It is important that nothing interfere
with the safety belt buckles so that the sen-
sors can send the correct information about
safety belt use to the electronic control unit. ..,.

148 Intelligent technology
Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da
ta Recorder (EDR), installed by some manu
facturers fo r the express purpose of capturing
data for retrieval after an accident or crash
event . EDR's are sometimes called "crash re
corders".
Some state laws restrict the retrieval or down
loading of data stored by EDR's that were in
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
A lthough your vehicle is not equipped with an
EDR, it is equipped with a number of electron
ic control modules for various vehicle systems
such as, for example, engine function, emis
sion control, as well as for the airbags and
safety belts .
These electronic control modules also record
vehicle-related data during normal vehicle op
eration for diagnostic and repair purposes.
The recording capacity of the electronic con
trol modules is limited to data (no sound is re
corded) and only a small amount of data is ac
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as well as restraint
system use and performance in the event of a
crash or other condition. Stored data can only
be read and downloaded with special equip
ment.
Electronic Stabilization
Program (ESP)
General
The Electronic Stability Program increases
driving stability.
With ESP, control over the vehicle is increased
in situations when the vehicle is close to the
limits of grip, such as during acceleration and
in curves . ESP reduces the risk of skidding and
improves vehicle stability under all road con
ditions.
It operates at all speeds.
The Anti -Lock Brake System (ABS), Electronic
Differential Lock (EDS) and Anti-Slip Regula
tion System (ASR) are integrated in the Elec
tronic Stability Program .
How ESP works
The ESP control unit processes the following
data from high-sensitive sensors : the rota
tional speed of the vehicle about its vertical
axis , fore-and-aft and lateral acceleration
forces, brake pressure and steering angle.
Using steering angle and vehicle speed, the
direction the driver wishes to travel is deter
mined and continuously compared with actual
vehicle behavior. If the two do not match, for
example when the vehicle begins to skid, ESP
brakes the appropriate wheel automatically.
The vehicle is stabilized again by the forces
acting on the wheel during braking. With an
oversteering vehicle (tendency for the rear end to skid out of the curve), the brake appli
cation is mainly at the front wheel on the out
side of the curve, with an understeering vehi
cle (tendency to run wide in the curve) at the
rear wheel on the inside of the curve or addi
tionally at the other wheels as needed. This
brake application is accompanied by noises.
ESP works in conjunction w ith ABS
~ page 153. If there is malfunction in the
ABS, ESP is also inoperative.
Page 151 of 260
A WARNING
- The limits of physics cannot be suspended by ESP. Even in vehicles w ith ESP, you
should always adapt your driving to road
and traffic conditions. This is particular ly
t rue on a slippery and wet road. Do not
be tempted by the inc reased safety pro
vided to take ris ks - danger of an acci
dent!
- Please note tha t when ESP/ASR is deacti
vated, the drive whee ls can spin on icy
and slippery roads and the veh icle can
break away - danger of skidding!

activated, the d rive wheels can spin on icy
a nd slippery roads and th e vehicle can
b reak away- dange r of skidd ing!
a) Tips
- If Aud i magnetic ride* is malfunct io ni ng,
the ESP may not sw itch off or it may
switch off automatically.
- In the event of a defect in the rear spoil er sys tem or in Audi magnet ic ride, it can
happen that ASR and ASR/ESP cannot be
deactivated, o r they are ac tiva ted au to
matically in the deactiva ted st ate.
Electronic differential lock (EDL)
The electronic differential lock monitors the
rotational speed of the drive wheels.
General notes
The electronic d ifferential lock (EDL) helps the
ca r to start moving, accele rate and climb a
gradient on su rfaces provid ing poor or a lmost
no g rip. Withou t EDL, this would be d iff icul t ,
i f not impossib le.
How the system works
The EDL operates automatica lly. It mon itors
the rotational speed of the dr ive wheels on an
axle with the help of the ABS sensors
c;:> page 153. If a noticeable difference in ro
tational speed
between the drive wheels on
o ne axle is detected (e.g. on s lippery ground
on one side), the s pinning wheel is braked,
thereby t ransferring power to the other drive
whee l or wheels (a ll-wheel drive). This is done
up to a speed of about 60 mph (100 km/h). ..,_
Page 152 of 260
150 Intelligent te chn olog y
Noises from the b rake system signal that
wheel spin is being controlled.
Driving off
When drivi ng off, a lways be sure to keep road
conditions in mind as you accelerate. If one
d rive wheel spi ns because it is on a surface
with less grip, gradua lly increase the press ure
on the accelerator pedal until the car starts to
move. The wheel less able to transfer power
spins.
O verheating of bra kes
To prevent the disc brake of the braked wheel
from overheating if subjected to excessive
loads, the EDL cuts out temporarily. The vehi
cle rema ins operationa l and behaves in the
same way as a vehicle without EDL.
As soon as the brake has cooled down, EDL
switches on again automatically .
A WARNING
-When accelerating on slippery surfaces,
such as on ice or snow, always be careful
when depressing the acce lerator pedal.
Even with the EDL working, the drive
wheels can spin and reduce yo ur ability
to contro l your car. -Risk of crash!
- The increased safety afforded by EDL
does not mean that you can ta ke safety
risks. Always adapt your dr iving sty le to
the road conditions and traff ic situa tion.
@ Tips
If a fa ult occurs in the ABS, the EDL is also
not f unct ion ing. This is indicated by the
ABS warning light ¢
page 17.
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the
driven wheels from spinning wh en the car is
accelerating.
General notes
The Anti-Slip Regulation System (ASR) is inte
grated in the electronic stabilization program
(ESP). When th e vehicle starts up and acceler- ates, the whee
ls are prevented from spinning
by adjusting the engine power to match the
amount of grip available from the road sur
face.
How the system works
ASR pe rforms a utomat ica lly, i.e . w ithout t he
driver's intervention. With the aid of the ABS
sensors ¢
page 153, ASR monitors t he speed
of the dr iven whee ls . If the whee ls start to
spin, the engine torq ue is reduced automati
cally until the tires find enough gr ip to lock
onto the road surface . The system is active
across the ent ire speed range .
The ASR works in conjunction with the ABS. If
a malfunction should occur in the ABS, the
ASR w ill also be out of act io n.
@ Tips
To ensure that the ASR works properly, all
four whee ls must be fitted wit h ident ica l
tires . Any differences in ro lling radius of
the tires can cause the system to reduce
engine power wh en this is not desired. See
a lso
¢ page 205, New tires and repla cing
tires and wheels.
Rear spoiler
The rear spoiler improves vehicle handling
and enhances driver control .

Page 155 of 260
Anti-lock brake system (ABS)
ABS prevents the wheels from locking under braking.
The anti-lock brake system (ABS) makes a ma
jor contribution to increasing active dr iving
safety. You should not expect that braking d is
tances will be
shortened under all circumstan
ces with ABS. Braki ng d istance may even be
come somewhat
longer, for example, on grav
e l or in new snow on slippery g round, even if
you are driving care fully and s low ly.
ABS operation
When a vehicle speed of about 10 mph (20
km/h) is reached, an automatic test sequence
is run. Some noise from the pump may be au
d ible.
I f the speed of a wheel slows down too much
r e lative to veh icle speed and it starts to lock,
brake pressure to this wheel is reduced. This
ad justment process can be felt as a
pul sin g
moti on of the br ake pedal , accompanied by
some noises. You as the driver are intentiona l
ly being given the information that the whee ls
are tending to lock (ABS control range). In or
der for ABS to be able to operate optimally in
this range, you must keep the brake pedal de pressed - do not "pump the brakes ".
Brake a ssist ant
The brake power assist unit increases the
pressure that you generate with the brake
pedal. It works only w hen the eng ine is run
ning .
Automatic full br ak ing
This function allows full brak ing in spite of
high brake pedal forces (e.g. when the brakes
are 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 travel. When the brake pedal is released, fu ll braking assist switches off again
automatically .
Intellig ent technolog y 153
If there is an ABS failure, the b rake assistant
and automatic fu ll braking assist are not avail
able.
A WARNING
- ABS cannot suspend the laws of physics.
You should keep th is in mind in particu
lar on an icy or wet road . If ABS control
of braking intervenes, you should adjust
your speed immed iately to road and traf
fic conditions. Do not be tempted by the increased safety provided to take risks -
danger o f an accident .
- Please keep in mind tha t the risk of an
accident is increased by driving too fast,
particularly in bends and on icy or wet
roads, and by driving too close to the ve
hicle ahead . The increased risk of an acci
dent cannot be reduced by the brake as
sistant - danger of an accident.
(D Tips
If a malfunction occurs in the ABS, this is
s ignalled by an indicator light, see
<=:> page 17.
Electro-mechanical
power assist
The electro-mechanical power assist helps
the driver when steering .
The degree of power assist is electronically
matched to vehicle speed.
The power steering system assists the driver
so that he can steer the vehicle with reduced physical effort .
Power steering will not work if the engine is
off . As a result, the steering wheel will be hard
to turn .
A WARNING
If the system develops a problem, you
must seek qualified professiona l assis
tance.

Fabrics and fabric coverings
Fabrics and fabric coverings (e .g. seats, door
trim panels, etc.) should be cleaned at regular
interva ls with a vacuum cleaner. T his removes
surface dirt particles which could become em
bedded in the fabr ic through use. Steam
cleaners should not be used, because the
steam tends to push the dirt deeper into the
fabric and lock it there.
Norm al cleaning
Generally, we recommend using a soft sponge
or a lint-free microfiber cloth to the clean fab
ric. Brushes should only be used for carpets
and floor mats, s ince other fabric surfaces
could be harmed by b rushes .
Normal surface sta ins can be cleaned using a
commercially available foam cleaner . Spread
the foam on the surface of the fabric with a

remove the rema in ing detergent. Apply the
water with a damp cloth or sponge and pat
the fabric dry with an absorbent, dry cloth.
Stains from choco late or makeup should have
detergent paste (e.g . ox-gall soap) rubbed in
to them. Afterwards, remove the soap with
water (damp sponge).
A lcohol can be used to treat stains from
grease, o il, lipstick or a ballpoint pen. Melted
