130 Safety belts
Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for
people riding in vehicles .
Fig. 123 Unbelted occupants in a ve hicle heading for a
wall
Fig. 124 The vehicle c ras hes into the wall
The physical principles are simple. Both the
vehicle and the passengers possess energy
which varies with vehicle speed and body
weight . Engineers call this 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 doubles from 15 to 30 mph (25 to
50 km/h), the energy increases 4 times!
Because the passengers of this vehicle are not
using safety belts¢
fig. 123, they will keep
moving at the same speed the vehicle was
moving just before the crash, until something
stops them -here, the wall¢
fig. 124 .
The same principles 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 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.
People who do not use safety belts are also
not attached to their vehicle. In a frontal colli­
sion they wi ll also keep moving forward at the
speed their vehicle was travell ing just before
the crash. Of course, the laws of physics don't
just apply to frontal collisions, they determine what happens in all kinds of accidents and col ­
lisions .
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!
Fig. 12S A driver not wea ring a safety belt is vio len tly
t hrown forward

Unbelted occupants are not able to resist the
tremendous forces of impact by holding tight
or bracing themselves . Without the benefit of
safety restraint systems, the unrestrained oc­
cupant will slam violently into the steering
whee l, instr ument panel, windshield, or what­
ever else is in the way r:!>fig . 125 . This impact II>-

with the vehicle interior has all the energy
they had just before the crash.
Never rely on air bags a lone for protec tion.
E ven when they deploy, airbags provide only
additional protection . Ai rbags are not sup­
posed to deploy in all kinds of accidents. Al­
though your Audi is equipped with a irbags, all
veh icle occupants, including the driver , must
wear safety belts correctly in order to min i­
mize t he risk of severe injury or death in a
crash .
Remember too, that airbags wi ll deploy on ly
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 a lready deployed . U nbelted
occupants ca n also be thrown out of the vehi ­
cle whe re even mo re severe o r fa tal in ju ries
can occur .
It is also impo rtant fo r the rear passenge rs to
wear safety belts co rrec tly. Unbe lted passen­
ge rs i n the rea r seats endanger no t on ly them­
se lves bu t also the driver a nd o ther passen­
gers
¢ fig. 126 . In a frontal collision they will
be thrown forward vio lent ly, where they can
h it and injure the dr iver and/or front seat pas­
senger .
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!
F ig . 127 D river is correctly restra ined in a sud den bral<·
ing maneuve r
Safety belts used properly can make a big dif­
ference . Safety be lts he lp to keep passengers
in their seats, gradually reduce energy levels
Safety belts 131
applied to the body in an accident, and he lp
prevent the uncontrolled movement that can
ca use serio us injuries . In addition, safety be lts
reduce the danger of being thrown out of the
vehicle.
Safety be lts attach passengers to the car and
give t hem the benefit of being s lowed down
more gently or "softly" through the "give" in
the safety belts, crush zones and other safety
features enginee red into today's vehicles. By
"absorbing" t he kinetic energy over a longer
per iod of t ime, the safety be lts make the
fo rces on the body more "tolerable" and less
li kely to ca use inju ry.
Althoug h these examples a re based o n a fron­
ta l co llision, safety belts can a lso substantia l­
l y red uce the risk of in jur y in other kinds of
cr ashes. So, whethe r you're on a long trip o r
just going to the co rner store, a lways buckle
u p and make sure others do, too . Accident sta ­
tistics show that vehicle occupants properly
wearing safety belts have a lower risk of be ing
i njured and a much better chance of surviving
an accident. Properly using safety belts also
greatly increases the ability of the supplemen ­
ta l airbags to do the ir job in a collision . Fo r
th is reason, wearing a safety belt is legally re­
quired in mos t coun tries including much of
t he United States and Canada.
Althoug h your Aud i is equipped wi th a irbags,
you st ill have to wear the safety be lts p rov id­
ed . Front airbags, fo r example, a re activa ted
o nly in some frontal collisions. The fron t air­
bags are not act ivated in a ll fron tal coll isions,
in s ide and rear co llisions, in roll ove rs or in
cases where t here is not eno ugh deceleration
through impact to the front of the veh icle.
The same goes for the other a irbag systems in
your Audi . So, always wear your safety belt
and make su re everybody in your veh icle is
properly restrai ned!

-Never place additional items on the seat
that can increase the total weight regis­
tered by the weight-sensing mat and can
cause injury in a crash.
Front airbags
Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat o ccupan ts.
F ig . 13 2 Location of driver airbag: in steer ing whee l
Fig. 133 Location of front passenger's airbag: in the in ­
st rument panel
Your veh icle is equipped w ith an "Advanced
Ai rbag System" in compliance with United
States Federal Motor Vehicle Safety Standard (F MVSS) 208 as app licab le at the time your
ve hicle w as manufac tured. The system senses
the position of the front seats and controls
front airbag inflation with a va lve, depending
on the distance between the respect ive seat
and the steering wheel or instrument panel.
The safety belts for the seats have "preten­
sioners" that he lp to take slack out of the belt
system . The pretensioners are also activated
by the electron ic contro l unit for the airbag
sys tem.
A irba g sy stem 141
The front sa fety belts also have load limiters
to help reduce the forces applied to the body
in a crash .
T he airbag for the drive r is in the stee ring
whee l hub
q fig. 132 and the airbag for the
front passenger is in the instrument panel
~ fig. 133 . The general locat ion of the a irbags
is marked "AIRBAG".
There is a lot you need to know about the ai r­
bags in your vehicle . We urge you to read t he
detailed information about airbags, safety
belts and child safety i n 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 yo ur passengers, especially in­
fants and small children.
_&. WARNING
N ever rely on airbags alone for protec tion.
- E ven w hen they deploy, airbags provide
only s uppleme nta l pro tect ion .
- Airbag work most effective ly when used
wit h properly wor n safety belts.
- Therefore, always wea r you r safe ty belts
and make sure that eve rybody i n your ve­
hicle is p rope rly res trained.
_&. WARNING
A pe rson on the fron t passe nger seat, es­
pe cial ly infants and sma ll children, will re­
ceive serious injuries and can even be kil­ l ed by being too close to the airbag when
it inflates .
- Altho 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 specia l
conditions is imposs ible i n all conceiva­
b le sit uat ions that may happen during
t he u seful life of your vehicle.
- The Advanced Airbag System can dep loy
in acco rdance with t he "low risk" option
un der the U.S. Fede ral Standa rd if a child
that is he avie r than the typical one-year
-
..

Fo r exa mple, the airbag may 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 whether the child is in one of
the chi ld safety seats listed
¢ page 163),
-a ch ild who has outgrown child rest raints is
on the front passenger seat.
I f the front passenger airbag is turned off , the
PA SSENGER AIR B AG OFF light in the center
of the inst rument panel w il l come on and stay
on.
The front a irbag on the passenger side may
not deploy (the PASSENGER 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 upr ight w ith
their back against a non-reclined backrest
with their feet on the veh icle floo r in front
of the sea t is on the front passenge r 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 inj ury through in teraction
with the airbag . "Low risk" deployment occurs
in those crashes that take place at lower de ­
celerations as defined in the electronic control unit.
¢ page 147
Alway s remember : Even though 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.
_&. WARNING
To reduce the risk of injury when an airbag
inflates, always wear safety belts properly .
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, your risk of injury is much highe r.
- You w ill also receive serious injuries and
could even be killed if you are up against
the a irbag or too close to it when it in-
A irbag system 143
flates - even with an Advanced Ai rbag
¢page 137.
_&. WARNING
A child in a rearward-fac ing ch ild safety
seat installed on the front passenger seat
will be ser ious ly injured and can be killed if
the front airbag inflates - even with an Ad­
vanced A irbag System .
-Although the Advanced Airbag System in your veh icle is designed to turn off the
front airbag when a rearward-facing child restraint has been instal led on the
front passenge r seat, nobody can abso­
lutely guaran tee that dep loymen t is im ­
possible in all conceivable situations that
may happen during the usefu l life of your
veh icle.
- The inflating airbag will hit the child
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the backrest, center
armrest, door, or roof .
-Always install rearward -facing chi ld re ­
straints in the back seat.
- If you must install a rearward fac ing
child safety seat on the front passenger
seat because of exceptional c ircumstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im­
mediately insta ll the rear-fa cing ch ild
safety seat in a rear seating position and
have the airbag system inspected by your
author ized Audi dealer .
A WARNING
-=
If, in exceptiona l circumstances, you must
install a forward-facing child restraint on
the front passenger's seat:
- Always make s ure 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.

-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-
Airbag system 151
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.
- In accidents when an airbag is deployed,
the vehicle battery separates the alterna­
tor and the starter from the vehicle elec­
trical system for safety reasons with a pyrotechnic circuit interrupter.
- 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.
@ 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-
ch lorate. When the vehicle or parts of the
restraint system including airbag modules
safety belts with pretensioners are scrap­
ped , all applicable laws and regulations
must be observed. Your authorized Audi
dealer is familiar with these requirements
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

ESC includes and/or works together with the
anti-lock brake system (ABS), brake assist sys ­
tem, anti -slip regulation (ASR) , e lectronic dif­
ferential lock (EDL), dynamic steering* and electronic i nteraxle differential lock* /selective
wheel torque control* . ESC is switched on all
the t ime. I n certain s ituations when you need
less traction, you can switch
off ASR by press­
i ng the button~~
page 182, fig. 153 or
~ page 182, fig. 154. Be sure to sw itch ASR
on again when you no longer need less trac­
tion.
Anti-lock b ra king s ystem (ABS)
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered
even d uring hard brak ing . Apply ste ady p res­
sure to the brake pedal. Do not pump the ped­
a l. A pulsing in the brake peda l indicates t hat
the system is he lping you to brake the vehicle.
Brake assist system
The brake assist system can decrease bra king
d istance. It increases braking power when the
d river presses the brake pedal quick ly in emer­
gency situations . You must press and hold the
brake peda l until the situation is over. In
veh icles w ith adaptive cru ise contro l*, the
brake assist system is more sensit ive if the
d istance detected to the veh icle ahead is too
small.
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 eas ier to
start, accelerate and drive up hills.
Elect ronic diffe renti al lo ck (EDL )
The ED L brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or wheels 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 automatica lly switches
off to help keep the brake on the braked whee l
from overheating. EDL w ill switch on again au-
Intellig ent technolog y 181
tomat ica lly when conditions have returned to
norma l.
Dynamic steering*
On vehicles with dynam ic steering*, ESC helps
stab il ize the s teer ing in crit ica l sit uat io ns.
Electronic interaxle differential lock* /
selective wheel torque control*
T he electronic i nteraxle differential lock (front
whee l dr ive) or the se lective whee l to rque
control (all-wheel dr ive) opera tes when dr iv­
ing thro ugh curves. The front wheel on the in­
side of the c urve or both whee ls on the inside
of the curve are braked selectively as needed .
This min imizes sliding in the front wheels and
allows for more precise driving through
cu rves . The applicable system may not acti­
vate when dr iv ing in wet or snowy conditions.
A WARNING
- ESC, ABS , ASR, EDL dynam ic steering*
a nd the elect ronic interaxle differential
loc k* /se lective wheel torque control*
cannot overcome the laws of physics .
This is especially important on slippery
or wet roads. If the systems begin acting
to stabilize your veh icle, yo u should im­
mediately change your speed to match
the road and traff ic conditions. Do not
let the increased safety provided by
these systems tempt you to take r isks.
Doing so will increase the risk of a loss of
veh icle contro l, col lision and ser ious per­
sonal injuries.
- Always adapt your speed to road, traffi c
and wea ther conditions. The risk of los­
ing contro l of the vehicle increases when
driving too fast, espec ially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead. ESC, ABS, the brake ass ist sys­
tem, ASR, EDL dynam ic steering* and the
electronic interaxle differentia l lock*/se­
lective whee l torque control* cannot p re-
vent co llisions . ..,.

Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a tra iler, p lease remember
that the addit ional load will affect durab ility,
economy and performance .
T railer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
F or this reason, a lways fo llow the operating
and driving instructions provided and use
common sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer we ight. The hitch must be suita­
b le for your veh icle and trailer and must be
mounted secure ly on t he veh icle's chassis at a
technically sound location . Use only a t railer
h itch w ith a removab le ball moun t. A lways
check with the tr ailer hitch man ufac tur er to
make sure that you are using the correct
hitch.
Do not use a bumper hitch.
T he hitc h must be installed in such a way that
it does not inte rfe re with the impac t-absorb­
i ng b umper syst em. No modifica tions should
be made to the vehicle exhaus t and b rake sys­
tems . From t ime to time, check that a ll hitch
mo unt ing bolt s remain securely fas tened.
W hen you are not tow ing a trailer, remove the
