Safety belts
-Failure to pay attention to the warning light
that come on, could lead to personal injury.
Why use safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for peo
ple riding in vehicles.
F ig. 147 Unbelted occupants in a vehicle heading for a wall
Fig . 148 The vehicle crashes into the wall
The physical principles are simple. Both the vehi
cle and the passengers possess energy which varies with vehicle speed and body weight. Engi
neers call this energy "kinetic energy."
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 doubles from 15 to 30 mph (25 to 50 km/
h), the energy increases 4 times!
Because the passengers of this vehicle are not us
ing safety belts¢
fig . 147, they will keep moving
at the same speed the vehicle was moving just
before the crash, until something stops them -
here, the wa ll
c> fig. 148.
136
The same principles apply to people sitting in a
vehicle that is invo lved in a frontal collision. Even
at city speeds of 20 to 30 mph (30 to 50 km/h),
the forces acting on the body can reach one ton
(2,000 lbs, or 1,000 kg) or more. At greater
speeds, these forces are even higher .
Peop le who do not use safety belts are also not
attached to their vehicle. In a fronta l co llision
they will also keep moving forward at the speed
their vehicle was travelling just before the crash.
Of course, the laws of phys ics don't just apply to
frontal coll is ions, they determine what happens
in all kinds of accidents and collisions.
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!

Unbelted occupa nts are not able to resist the t re
mendous forces of impact by holding tight or
bracing themselves. Without the benefit of safe
ty restraint systems, the unrestrained occupant
will slam violently into the steering wheel, .,.

instrument panel, windshield, or whatever else is
in the way~
fig. 149. This impact with the vehi
cle interior has all the energy they had just before
the crash.
Never rely on airbags alone for protection. Even
when they deploy, airbags provide only additional
protection. Airbags are not supposed to deploy in
all kinds of accidents. Although your Audi is
equipped with airbags, all vehicle occupants, in
cluding the driver, must wear safety belts cor
rectly in order to minimize the risk of severe in
jury or death in a crash.
Remember too, that airbags will deploy only once
and that your safety belts are always there to of
fer protection in those accidents in which airbags
are not supposed to deploy or when they have al
ready deployed . Unbelted occupants can also be
thrown out of the vehicle where even more severe
or fatal injuries can occur.
It is also important for the rear passengers to
wear safety belts correctly . Unbelted passengers
in the rear seats endanger not only themselves
but also the driver and other passengers
¢ fig. 150. In a frontal collision they will be
thrown forward violently, where they can hit and
injure the driver and/or front seat passenger.
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. 151 Driver is correc tly restra ined in a sudden braking
maneuve r
Safety belts used properly can make a big differ
ence. Safety belts help to keep passengers in
their seats, gradually reduce energy levels ap-
Safety belts
plied to the body in an accident, and help prevent
the uncontrolled movement that can cause seri
ous 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 engi
neered 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 frontal collision, safety belts can also substantially re
duce the r isk of injury in other kinds of crashes.
So, whether you're on a long trip or just going to
the corner store, always buckle up and make sure
others do, too. Accident statist ics show that vehi
cle 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 supplemental airbags to do their job in a col lision. For this reason, wearing a safety belt is le
gally required in most countries including much
of the United States and Canada.
Although your Audi is equipped with airbags, you still have to wear the safety belts provided. Front
airbags, for example, are activated only in some
frontal coll isions. The front airbags are not acti
vated in all frontal coll is ions, in side and rear col
lisions, 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 correctly positioned
across the strongest bones of your body.
.,. Always wear safety belts as illustrated and de
scribed in this chapter.
.,. Make sure that your safety belts are always
ready for use and are not damaged.

Airbag syste m
A WARNING
Objects between you and the a irbag w ill in
crease the risk of injury in a crash by interfer
ing with the way the airba g unfo lds and/or by
being pus hed into you as the airbag inflates.
- Always make sure nothing is in the front air-
bag depl oyment zone that could be struck
by the airbag when it inflates.
- Objects in the zone of a deploying a irbag
can become project iles when the airbag de
ploys and cause serious personal injury.
- Never hold things in your hands or on your
lap when the vehicle is in use .
- Never place accessor ies or other objects
(such as cup holders, telephone brackets,
note pads, navigation systems, or things
that are large, heavy, or bulky) on the doors; never attach then to the doors or the wind
shield; never place them over or near or at
tach them to the area marked ,.AIRBAG" on
the steering wheel, instrument pane l or the
seat backrests; never place them between
these a reas and you or any other person in
the vehicle .
- Never attach objects to the windshield
above the passenger front airbag, such as
accessory GPS navigation units or music players. Such objects co uld cause serious in
jury in a collision, especially when the a ir
bags inflate.
- Never recline the front passenger seat to transport objects. Items can also move into
the deployment area of the side airbags or
the front airbag dur ing breaking or in a sud
den maneuver . Objects near the a irbags can
fly dangerously th rough the passenger com
partment and ca use i njur y, partic ularly
when the seat is reclined and the airbags in
flate .
A WARNING
A person on the front passenge r seat, espe
cially infants and small children, wi ll receive
serious injuries and can even be killed by be
ing too close to the airbag when it inflates.
- Although the Advanced Airbag System in
your vehicle is designed to turn off the front
148

passenger airbag if an infant or a small child
is on the front passenger seat, nobody can
absolutely guarantee that dep loyment un
de r these specia l condit ions is impossible in
all conceivable situations that may happen
during the useful life of yo ur vehicle.
- The Advanced Airbag System can dep loy in
accordance with the ,,low risk" option for 3-
and 6-year-o ld children under the U.S. Fed

strained in one of the forward facing or rear
ward-facing child seats with which your ve
hicle was certif ied is on the front passenger
seat and the other conditions for airbag de
ployment are met.
- Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seating position .
- For their own safety, all ch ildren, especially
12 yea rs and younger, should a lways ride in
the back properly restrained for their age
and size .

A WARNING
A child in a rearward-facing child seat instal
led on the front passenger seat wi ll be seri
ously injured and can be killed if the front air
bag inflates -even with an Advanced Airbag
System.
- Although the Advanced Airbag System in
your vehicle is designed to turn off the front
airbag when a rearward-facing child re
straint has been installed on the front pas
senger seat, nobody can absolutely guaran
tee that deployment is impossible in all con
ceivable s ituations that may happen dur ing
the usef ul life o f you r vehicle.
- The inf lating a irbag w ill hit the child seat or
infa nt carrier w ith great force and w il l
smash the ch ild seat and child agains t the
backrest, center armrest, door, or roo f.
- Always insta ll rearward -facing child re
straints on the rear sea t.
-If you mus t install a rearward facing chi ld
seat on the fron t passenger sea t beca use of
exceptional circ umstances and the
PASSEN
GER AIR BAG OFF light does not come on
and stay on, immediately install the rear
facing child seat in a rear seating position
and have the a irbag system inspected by
your Audi dealer.
A WARNING
If, in exceptional c ircumstances, you must in
stall a forward-facing chi ld restraint on the
front passenger 's seat:
-Always make sure the forward-fac ing seat
has been designed and ce rtified by its man
ufact urer for use on a front seat wit h a pas
senger front and side airbag.
- Never put the forwa rd-facing child rest raint
up against or ve ry nea r the instrument pan
el.
- Always move the passenger seat into its
rearmost position in the se at's fore and aft
adjustment range, as far away from the air
bag as possib le, before installing the fo r
war d-fac ing c hild restraint . The backrest
must be adjuste d to an up right position .

-
-Always ma ke sure that there is nothing on
the front passenger seat that w ill cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that
the seat is occup ied by a person when i t is
not, or to s ignal that it is occupied by some
one who is heavier than the person a ctua lly
si tti ng on the se at. T he presence of addi
tional objects could cause the p assenger
front airbag to be turned on when it s hou ld
be off, or co uld cause the a irbag to wo rk in a
way that is different from the way it would
have worked without the object on the seat.
- Make sure that the
PASSENGER AIR BAG
OF F light comes on and stays on all the time
whenever the ignit ion is switched on.
Advanced Airbag System components
The front passenger seat in your vehicle has a lot
of very impo rtant parts of the Advanced A irbag
System i n it. T hese pa rts include the capacitive
passenger detection system, wir ing, b ra ckets,
and more. The control u nit mon itors the system
o n the fron t passenger seat when the ign it ion is
swi tched on and turns the airbag indica tor ligh t
o n when a malfunction in the one of the system
components is detected~
page 155. Because
the front passenger seat contains important
parts of the Adv a need A irbag System, you must
take care to prevent it from being damaged .
Damage to the seat may prevent the Advanced
A irbag System for the front passenger seat from
do ing its job in a crash.
The front Advanced Airbag Sy stem consists
of the following:
- Cras h sensors in the front of the vehicle that
measu re vehicle acceleration/deceleration to
provide i nfo rmat ion to the Advanced Airbag
System abo ut the sever ity of the cr ash.
- An ele ct ro nic contro l unit, with integrated
crash sensor s for front and s ide impac ts. The
cont ro l uni t "dec ides" whether to fire the fron t
airbags based on the information received from
the crash se nsors . The control unit a lso "de
cides" whether the sa fety belt pretensioners
should be activated. ..,_

rate. When the vehicle or parts of the re
straint system including airbag modules and
safety belts w ith pretens ioners are scrapped,
all applicable laws and regulations must be
observed. Your authorized Audi dealer is fa
miliar with these requirements and we recom
mend that you have your dealer perform this
service for yo u.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced A irbag System
performs in a crash. For example, using tire-rim
comb inat ions not approved by Audi, lowering the
vehicle, changing the stiffness of the su spension,
including the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
e lectronic control un it. Some suspension changes
can, for example, increase the force levels meas
ured 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 measured by
the sensors and prevent the airbag from deploy
ing when it should.
_& WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in
crease the risk of ser ious personal injury in a
crash.
- Never install suspens ion components that
do not have the same performance charac
teristics as the components originally instal
led on your veh icle.
- Never use tire-rim combinations that have
not been approved by Audi.
Airbag system
Knee airbags
Description of knee a irbags
Applies to vehicles: with knee airbags
The knee airbag system can provide supplemen
tal protection to properly restrained front seat
occupants .
Fig. 161 D river 's knee a irbag
T he driver knee airbag is in the instrument panel
underneath the steering wheel
¢fig.161, the
airbag for the passenger is at about the same
height in the instrument panel underneath the
glove compartment.
The knee airbag offers additional protection to
the driver's and passenger's knees and upper and
lower thigh areas and supplements the protec
tion provided by the safety belts.
If the front airbags dep loy, the knee airbags also
deploy in frontal collisions when the dep loyment
threshold stored in the control unit is met
¢ page 152 , More important things to know
about front airbags .
In addition to their normal safety function, safe
ty belts help keep the driver or front passenger in
position in a frontal collision so that the airbags
can provide supplemental protection .
The airbag system is not a substitute for your
safety belt . Rather, it is part of the overall occu
pant restraint system in your vehicle. Always re
member that the airbag system can only help to
protect you if you are wearing your safety belt
and wearing it properly. This is why you should a l
ways wear your safety belt, not just because the
law requires you to do so¢

Booster seats and safety belts
Properly used booster seats con help protect
children weighing between about 40 lbs. and 80
lbs. (18 kg and 36 kg) who ore less than 4
ft. 9
in . (57 inches/1 .45 meters) tall .
Fig. 171 Rear seat: ch ild prope rly restrained in a booster
seat
"' ,-.
i i
The vehicle's safety belts alone will not fit most
children until they are at least 4
ft. 9 in . (57 in
ches/1.45 meters) tall and weigh about 80 lbs.
(36 kg). Booster seats raise these children up so
that the safety belt will pass properly over the
stronger parts of their bodies and the safety belt
can help protect them in a crash.
• Do not use the convertible locking retractor
when using the vehicle's safety belt to restrain
a child on a booster seat.
• The shoulder be lt must lie as close to the cen
ter of the child's collar bone as possible and
must lie flat and snug on the upper body. It
must never lie across the throat or neck. The
lap belt must lie across the pelvis and never
across the stomach or abdomen . Make sure the
belt lies flat and snug . Pull on the belt to tight
en if necessary.
• If you must transport an older child in a boos
ter seat on the front passenger seat, you can
use the safety belt height adjustment to help
adjust the shoulder portion properly .
176
• Secure unused safety belts on the rear seat
r=;, page 172 .
Children up to at least 8 years old (over 40 lbs or
18 kg) are best protected in child safety seats de
signed for their age and weight . Experts say that
the skeletal structure, particularly the pelvis, of
these children is not fully developed, and they
must not use the vehicle safety belts without a
suitable child restraint .
It is usually best to put these children in appro
priate booster seats . Be sure the booster seat
meets all applicable safety standards.
Booster seats raise the seating position of the
child and reposition both the lap and shoulder parts of the safety belt so that they pass across
the child 's body in the right places. The routing of
the belt over the child 's body is very important
for the child's protection, whether or not a boos
ter seat is used. Children age 12 and under must
always ride in the rear seat.
Children who are at least 4
ft. 9 in. (57 inches/
1.45 meters) tall can generally use the vehicle's
three point lap and shoulder belts . Never use the
lap belt portion of the vehicle's safety belt alone
to restrain any child, regardless of how big the
child is. Always remember that childr en do not
have the pronounced pelvic structure required for
the proper function of lap belt portion of the ve
hicle 's three point lap and shoulder belts. The
child's safety absolutely requires that a lap belt
portion of the safety belt be fastened snugly and
as low as possible around the pelvis . Never let
the lap belt portion of the safety belt pass over
the child's stomach or abdomen .
In a crash, airbags must inflate within a blink of
an eye and with considerable force . In order to do
its job, the airbag needs room to inflate so that it
will be there to protect the occupant as the occu
pant moves forward into the airbag .
A vehicle occupant who is out of position and too
close to the airbag gets in the way of an inflating
airbag . When an occupant is too close, he or she
will be struck violently and will receive serious or
possibly even fatal injury. .,..

Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of sk id
d ing and loss of veh icle control.
It works only
when the engine is runn ing. ESC detects certa in
d ifficult d riving situations, including when the ve
h icle is beginn ing to sp in (yaw) o ut of control and
he lps you to ge t the veh icle back u nder cont ro l b y
selec tively braking the whee ls, and/or reduc ing
engine power and providing steering assistance
to help hold the vehicle on the driver's i ntended
course. The indicator light
DJ in the instrument
cluster blinks when ESC is taking action to help
you control t he veh icle.
ESC has lim itations. It is important to remember
that ESC cannot overcome the laws of physics. It
will not a lways be ab le to he lp out under all con
d itions 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. Whe n
there is a section of d ry road tha t is s udden ly cov
ere d wi th wa ter, s lush or snow, ESC ca nnot per
form the same way it wou ld on the d ry s urface . If
the vehicle hydroplanes ( rides on a cushion of wa
ter instead of t he road surface), ESC wi ll not be
ab le to he lp you steer the veh icle because contact
with the pavement has been i nterrupted and the
ve hicle cannot be b raked or steered. Dur ing fast
cor ne ring, particula rly o n w inding roads, ESC
cannot a lways deal as eff ect ively wi th d iff icu lt
d riving situat ions than at lowe r speeds.
Always ad just your speed and dr iv ing style to
road, traffic and weather conditions. ESC ca nnot
over ride the vehicle's physical limi ts, increase t he
ava ilab le tract io n, or keep a vehi cle on t he road if
roa d de pa rture is a res ult o f driver in att enti on.
I nstead, ESC improves the poss ibility of keeping
188
the veh icle unde r control and on the road dur ing
extreme maneuve rs by using the dr iver's stee ring
i nputs to help keep the vehicle going in the in
tended direction. If yo u are traveling at a speed
that causes you to run off the road before ESC
can p rov ide any assistance, you may not experi
ence the benefits of ESC.
ESC is switc hed on all the time. In certain s itua
tions when you need less tracti on, you can switch
off ASR by press ing the button
[ru c:> page 189,
fig . 178. Be sure to sw itch ASR on aga in when
you no longer need l ess traction.
The following systems are integrated in the ESC:
Anti -lock braking system (ABS )
ABS prevents the whee ls from locki ng when brak
i ng . T he veh icle can st ill be stee red even during
hard braking. App ly steady pressure to the brake
pedal. Do not pump the pedal. A puls ing in the
brake pedal indicates that the system is acting to
stab ilize the veh icle.
Brake assist sy stem
The bra ke ass ist system can decrease braking dis
tance. It increases bra king power when the driver
presses the brake peda l quickly in emergency sit
uat ions. You must press and hold the b rake peda l
u nt il the dange rous situat io n is over . In vehicles
with adaptive cruise co ntro l*, the brake ass ist
system is more sensitive if t he d ista nce detected
to t he veh icle a head is too sma ll.
Anti-slip regulation (ASR)
ASR red uces eng ine power when the drive wheels
begin spin ning and adapts the force to the road
cond it ions . Th is makes it eas ier to sta rt, acce ler
ate a nd dr ive up incl ines.
Electronic differential lock (EDL)
EDL applies t he brakes to a whee l that starts
sp inning a nd tra nsfe rs the d rive power to the
othe r drivi ng whee ls. This function is not ava ila
ble at hig he r speeds.
In extreme cases, EDL automatically sw itches off
to keep the brake o n the braked whee l from over
hea ting. The vehicle is st ill work ing cor rect ly. EDL ..,.
M N <( I.J ""'. rl I.O

will switch on again automatically when
conditions have returned to normal.
Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque.
In vehicles with dynam ic steering*, ESC also
he lps to stabilize the steering in critical situa
tions.
Selective wheel to rque 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 i nside of the
curv e are braked selectively as needed . This al
lows more precise dr iving in curves.
Automatic post-collision braking system
The "Automatic post-collision braking system"
can help to reduce the risk of sliding and of other
collis ions after an accident. If the airbag control
module detects a coll is ion above a ce rtain veh icle
speed, the vehicle is braked by the ESC.
The vehicle does not brake automatically if:
- the driver presses the acce lerator pedal, or
- the braking force generated by the pressed
brake pedal is greater than the braking force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle electri
ca l system are not functioning.
Switching on/off
Intelligent Technology
A WARNING ,-
-The ESC and its integrated systems cannot
overcome the limits posed by natural phys i
cal laws. This is especially important on slip
pe ry or wet roads. If the systems begin act
ing to stabilize your vehicle, you should im
mediately alter your speed to match the
road and traffic conditions. Do not let the in
creased safety provided tempt you into tak
ing risks. This could increase your risk of a
collis ion.
- Please note the r isk of a collision increases
when driving fast, especially thro ugh curves
and on slippery or wet roads, and when driv
ing too close to objects ahead. The ESC and its integrated systems cannot always pre
vent collisions· there is still a risk of acc i
dents!
- Press the accelerator pedal carefully when
accelerating on even, slippery surfaces such
as ice and snow. The drive wheels can spin
even when these control systems are instal
led and this can affect driving stability and
i n crease the r isk of a coll ision .
(j) Tips
-ABS and ASR only function correctly when
all four wheels are equipped with identical
tires. Different tire s izes can lead to a reduc
tion in engine power .
- You may hear noises when the systems de
scribed are working.
ESC turns on automatically when you start the engine .

The following examples are unusual situations
where it may make sense to switch sport mode
on in orde r to allow the wheels to sp in:
- Rocking the vehicle to free it when it is stuck
- Driving in deep snow or on loose ground
- Driving with snow chains
