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 . 107 Driver is properly restrained in a sudden b rak­
i ng maneuve 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 tr ip or
just going to the corner store, always buckle
Safety belts 103
up and make sure others do, too. Accident sta ­
tistics show that vehicle occupants properly
wearing safety belts have a lower risk of be ing
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
th is reason, wearing a safety belt is legally re­
quired in mos t 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 coll isions,
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. 112 Location of dri ver airbag: in steering whee l
Fig. 113 Location 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 steering
wheel hub¢
fig. 112 and the airbag for the
front passenger is in the instrument panel
¢fig. 113. 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 113
detailed information 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 in ­
fants and small children.
A WARNING ,.;;
Never rely on airbags alone for protection .
- Even when they deploy, airbags provide
only supplementa l protection.
- 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 .
- Although the Advanced Airbag System in
your vehicle 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 impossible 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 heavier than the typical one-year
old child is on the front passenger seat
and the other condit ions for airbag de­
ployment are met.
- For its own safety, a child should always
ride properly restrained for its age and
size.

I f 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 injury through interaction
with the airbag . "Low risk" deployment occurs
in those crashes that take place at lower de­
celerations as defined in the electron ic control

Alw ays rem emb er: Please be sure to read the
important information in the sections that
follow and be sure to heed all of the WARN ­
INGS.
A 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 inj ury is much higher.
- You w ill also receive serious inju ries and
cou ld even be killed if you are up against
the a irb ag or too close to it when it in­
flates - even with an Advanced Airbag

.&_ 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.
- Although the Advanced Airbag System in
your 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 l u te ly guarantee that deployment is im­
poss ible in a ll conceivable situations that
may happen d uring the useful life of your
vehicle.

.&_ WARNING
I f, 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 for use on a front seat
with 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 adjustment range, as far away from
the airbag as possible, before installing
the forward-fac ing ch ild restra int. The
backrest must be ad justed to an upright
position.
- Make sure that the

Advanced Airbag System components
T he front passenge r seat in yo ur vehicle has a
lot of very important parts of the Advanced
Airbag System in it . These parts include the
weight-sensing mat, sensors, wiring, brack­ ets, and more. The funct ion of the system in
the front passenger seat is checked by the
electronic control unit when the ignition is on .
The cont rol unit monitors the Advanced A ir­

-Never modify the front bumper or parts
of the veh icle body.
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace­
ment upho lstery ove r the front seat­
backs that have not been spec ifically
approved by Audi.
- Never use add itiona l seat cushions that
cover the areas where the side airbags
inflate .
- Damage to the o rigina l seat covers or
to the seam in the area of the side air­
bag module must always be repa ired
immediate ly by an authorized Audi
dealer.
- The airbag system can be activated only
once . After an airbag has inflated, it
must be replaced by an author ized Audi
dealer or qualif ied technic ian who has
the techn ica l information, tra ining and
special equipment necessary.
- The airbag system can be deployed only
once. After an a irbag has been deployed,
it must be replaced w ith new replace­
ment parts designed and approved espe­
c ially for your Aud i model version. Re­

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 , traffic §&and weather conditions. ESC
cannot override the vehicle's physical limits,
increase the available traction, or keep a vehi­
cle 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 dur ing extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle go ing 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 togethe r 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-lock braking system (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 pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle.
Brake assist 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 si tuations. You must press and hold the
brake pedal until the situation is over .
Anti-slip regulation (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.
Electronic differential 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 overcome
th e laws of physics. This is especially im ­
portant on slippery or wet roads.
If the
systems begin acting to stabilize your ve­
hicle, you should immediately change
your speed to match the road and traffic
condit ions. Do not let the increased safe­
ty provided by these systems tempt you
Intelligent technology 143
to take risks. Doing so will increase the
risk of a lo ss 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, especially 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 prevent colli­
sions.
- 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 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 si zes 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¢
