102 Safet y belt s
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 safety belts!
F ig . 97 A driver not wearing a safety belt is violently
thrown forward
F ig. 98 A rear passenger not wearing a safety belt will
fly forward a nd strike the d river
Unbelted occupants are not able to res ist the
tremendous fo rces of impact by holding tight
or brac ing thems elves. Without the benefit of
safety restraint systems, the unres trained o c­
cupa nt w ill slam vio lent ly into the steering
wheel, instrument panel, winds hield, or what ­
ever else is in the way
q fig . 97 . This impact
with the vehicle interior has all the energy
they had just before the crash.
Neve r rely on airbags a lone for p rotection .
Even when they deploy, airbags provide only
addit ional protection . Airbags are not sup ­
posed to deploy in all kinds of accidents. Al­
though your Audi is equipped with a irbags, all
vehicle occupants, including the driver, must
wear safety belts correctly in order to min i­
mize the risk of severe inju ry or death in a
crash.
Remember too, that a irbags will deploy on ly
once and that your safety belts are always there to offe
r protection in those accidents in
which airbags are not supposed to dep loy or
when they have already dep loyed . Unbelted
occupa nts can also be thrown o ut of the ve hi­
cle where even more severe or fatal injuries
can occur .
It is also important for the rear passengers to
wear safety belts correctly. Unbelted passen­
gers in the rear seats endanger not only them­
se lves but also the driver and othe r passen­
gers¢
fig. 98 . In a frontal coll is ion they w ill
be th rown forward violently, where they can
hi t and i njur e the d river a nd/or fro nt sea t pas­
senger.
Safety belts protect
People think it's possible to us e the hands to
brace the body in a minor collision. It 's simply
not true!
Fig. 9 9 Driver is proper ly restrained in a sudden brak­
in g maneuve r.
Safety be lts used p roperly can make a big dif­
fere nce. Safe ty belts help to keep passengers
in the ir seats, gradua lly reduce energy leve ls
applied to the body in an accident, and he lp
prevent the uncontrolled movement that ca n
ca use serio us inju ries . In addition, safety be lts
reduce the danger of being thrown out of the
vehicle.
S afety be lts attach passenge rs 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

112 Airbag system
-An improperly installed child restraint
can interfere with the airbag as it de ­
ploys and seriously injure or even kill the
child -even with an Advanced Airbag
System .
- Always carefully follow the manufactur­
er's instructions provided with the child
safety seat or carrier.
- Never place additional items on the seat
that can increase the total weight regis­ tered by the weight-sensing mat and can
cause i njury in a crash .
Front airbags
Description of front airbags
The airbag system con provide supplemental
protection to properly restrained front seat
occupants.
Fig. 104 Location of driver airbag: in stee ring wheel
Fig. 105 Location of front passenger's air bag : in the in ­
st rume nt panel
Your veh icle is equipped with an "Advanced
A irbag System" in compliance w ith United
States Federal Motor Vehicle Safety Standa rd
(FMVSS) 208 as applicab le 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 a
lso activated by the e lec­
tronic contro l unit for the airbag system.
T he front safety belts also have lo ad lim ite rs
to help reduce the fo rces applied to the body
in a crash .
T he airbag for the d river is in the steering
wheel hub~
fig. 104 and the ai rbag for the
fron t passenger is in the instrument panel
~ fig. 105 . The general locat ion of the ai rbags
is marked "AIRBAG".
T he re is a lot you need to know about t he a ir­
bags in you r vehicle. We urge yo u to read the
detailed information abo ut airbags, safety
belts and child safety in this and the other
chapters that make up the owner's literature .
P lease 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 alo ne for protection .
- Even when they deploy, airbags provide
only supplemental protect ion.
- Airbag work most effective ly when used
with properly worn safety belts.
- Therefore, always wear your safety belts
a nd make sure that eve rybody in your ve­
h icle is p roperly rest rained.
A WARNING
A person on the front passenger seat, es­
pec ially infants and sma ll children, w ill re­
ceive serio us injuries and can even be kil-
l ed by be ing too close to the ai rbag when
i t inflates .
- Al tho ugh the Advanced Airbag System in
your veh icle is designed to tur n
off the
front passenge r 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 impossible in all conceiva­
b le situat ions that may happen during
-
the useful life of your vehicle . ~

114 Airbag sys te m
but less than the weight of a small adu lt, the
front airbag on the passenger side may deploy (the
PASSENGER AIR B AG OFF light does not
come on).
F or exa mple , the air b ag m ay depl oy if:
- a small child that is heavier than a typical 1
year-o ld child is on the front passenger seat
(regardless of whe ther the child is in one of
the chi ld safety seats listed
~ page 132),
- a ch ild who has outgrown child rest raints is
on the front passenger seat.
If the front passenger airbag is turned off, the
PA SSENGER AIR BAG OFF light in the cente r
of the instrument panel w ill come on and stay
on.
The front a irbag on the passenger side may
not deploy (the PAS SENGER AIR BAG OFF
light does not illuminate and stay lit) if:
- a small adult or teenager is on the front pas­
senger seat
- a passenger who is not sitt ing upright with
their back against a non-reclined backrest
with their feet on the veh icle floo r in front
of the seat is on the front passenger seat.
If the front passenger airbag deploys, the Federal Standard requires the airbag to meet
the "low risk " deployment criteria to help re­
duce the risk of inju ry through interaction
with the airbag . "Low risk" deployment occurs
in those crashes that take place at lower de­
celerations as defined in the e lectronic control
un it
~ page 119.
Alw ays re m emb er: Even tho ugh you r vehicle
is equipped with Advanced Airbags, the safest
p lace for children is properly restrained on the
back seat . Please be sure to read the impor­
tant information in the sect ions that follow
and be sure to heed all of the WARNINGS.
A WARNING
To reduce the risk of injury when an airbag
inf lates, always wear safety belts properly.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, your risk of in jury is much higher . -
You will a lso receive serious injuries and
could even be killed if you are up aga inst
the airbag or too close to it when it in­
flates - even w ith an Advanced A irbag
~ page 108 .
A WARNING '"----
A child in a rearward-fac ing ch ild safety
seat installed on the front passenger seat
will be serious ly injured and can be killed if
the front airbag infla tes - even with an Ad­
vanced A irbag System.
- Altho ugh the Advanced Airbag System in
your veh icle is de signed to turn off the
front airbag when a rearward -facing
child restraint has been installed on the
front passenger seat, nobody can abso­
lutely g uarantee that dep loyment 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 aga inst the bac krest, door, or
roof .
- Always install rearward-facing ch ild re­
straints in the back seat.
- If you must install a rearward fac ing
child safety seat on the front passenger
seat be cause of exceptiona l circumstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im­
mediately insta ll the rear -fac ing child
safety seat in a rear seating position and
have the airbag system inspected by your
Aud i dealer.
A WARNING
If, in exceptional circumstances, you must
i nstall 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 manufacture r fo r use on a front seat
with a passenger front and s ide a irbag .

@ For the sake of the environment
Undeployed airbag modules and preten­
sioners might be classified as Perchlorate
Material -special handling may apply, see
www.dtsc.ca .gov/hazardouswaste/per­
chlorate. When the vehicle or parts of the
restraint system including airbag modules
and safety belts with pretensioners are
scrapped, all applicable laws and regula­
tions must be observed. Your authorized
Audi dealer is familiar with these require­
ments and we recommend that you have
your dealer perform this service for you.
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 measured 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-
Airbag system 123
sors can send the correct information about
safety belt use to the electronic control unit.
A WARNING
Changing the vehicle's suspension includ­
ing use of unapproved tire-rim combina­
tions can change Advanced Airbag per­
formance and increase the risk of serious personal injury in a crash.
- Never install suspension components
that do not have the same performance characteristics as the components origi­
nally installed on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.
A WARNING
-
Items stored between the safety belt
buckle and the center console can cause
the sensors in the buckle to send the
wrong information to the electronic con­
trol module and prevent the Advanced Air­
bag System from working properly.
- Always make sure that nothing can inter­ fere with the safety belt buckles and that
they are not obstructed.

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 ca lled "crash re­
corders".
Some state laws restrict the retr ieval 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 examp le, eng ine function, em is­
sion control, as well as for the airbags and
safety belts.
These electronic contro l modules also record
vehicle-re lated 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 pe riod 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 we ll 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
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of vehicle control. It works
only when the engine is running. ESC detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering assistance to help hold the
vehicle on the driver's intended course. The in­
dicator light
G) in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
physics. It wi ll not always be able to help out
under all conditions 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. When there is a section of
dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it wou ld on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered.
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations as at lower
speeds.
Always adjust your speed and driving style to
road , traffi<;: and weather conditions. ESC can­
not override the vehicle's physical limits, in­
crease the available tract ion, or keep a vehicle
on the road if road departure is a result of
driver inattention . Instead, ESC improves the
poss ibility of keeping the vehicle under con­
t rol and on the road during extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle going in the intended di­
rection . If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC includes and/or works together with the
anti- lock brake system (ABS), brake assist sys-
tem and anti-slip regu lation (ASR). ESC is .,..

switched on all the time. In certain situations
when you need less traction, you can switch
off ESC by pressing the button
lru . Be sure to
switch ESC on again when you no longer need
less traction.
Anti -loc k brak ing s ystem (ABS )
ABS prevents the wheels from locking up
when braking . The vehicle can still be steered
even during hard braking. Apply steady pres­
sure to the brake pedal. Do not pump the ped­
al. A puls ing in the brake pedal indicates that
the system is helping you to brake the vehicle.
B rake ass is t system
The brake assist system can decrease braking
d istance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency situations. You must press and hold the
brake pedal until the situation is over .
Anti-slip regulati on (ASR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it easier to
start, accelerate and drive up hills.
Elect ronic diff erential lock (EDL )
The EDL brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h).
In extreme cases, EDL automat ica lly switches
off to help keep the brake on the braked wheel
from overheating. EDL w ill switch on again au­
tomatically when conditions have returned to normal.
..&, WARNING
- ESC, ABS, ASR and EDL cannot ove rcome
t he laws of physics. This is espec ia lly im ­
portant on slippery or wet roads.
If the
systems begin act ing to stab ilize your ve­
hicle, you should immediately change
yo ur speed to match the road and traffic
condit ions. Do not let the increased safe­
ty provided by these systems tempt you
Intelligen t technolog y 151
to take risks. Doing so will increase the
risk of a loss of vehicle control, co llision
and serious personal injuries.
- Always adapt your speed to road, traffic
and weather conditions. The risk of los­
ing control of the vehicle increases when
driving too fast, espec ially through
curves and on slippery or wet roads, and
when driving too close to vehicles up ahead. ESC, ABS, the brake assist sys­
tem, EDL and ASR cannot preven t coll i­
sions.
- Always ac celera te with spe cial care on
even, smooth s urfaces su ch as those th at
are wet or covered with ice and snow.
The drive wheels can spin even with these assistance systems that cannot al ­
ways he lp to reduce the risk of loss of ve­
hicle control.
@ Tips
- ABS and ASR only work correct ly when
all four whee ls are equipped with identi­
cal tires. D ifferent tire sizes can lead to a
reduction in engine power.
- You may hear noises when the systems described are working.
-If the ind icator lightD] orE (USA
models)/ [iJ (Canada models) appears,
there may be a malfunction¢ page 18,

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
soft sponge and work it in gently . Do not satu­
rate the fabric. Then pat the foam d ry using
absorbent, dry cloths (e.g. microfibe r clo th)
and vacuum it afte r it has dr ied comp lete ly.
Cl eaning stains
Stains caused by beve rages (e .g. coffee, fruit
juice, etc.) can be t reated with a mild deter­
gent solution. App ly the dete rgent so lution
wi th a sponge. In the case of s tubbor n stains,
a detergent paste can be applied directly to
Cleaning and protec tion 17 1
the stain and worked into the fabric. After ­
wards, use copious amounts of clean water to 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
grease or dye must be patted off using ab­
sorbent mater ial. It may be necessary to re­
treat the areas with detergent paste and wa­
te r.
In the case of genera l soiling of the uphols­
tery and cover material, we recommend hir ing
a specia list that has the equipment to clean
t h e seat covers and othe r fabr ic surfaces by
shampooing and spray extraction .
