Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for
people riding in vehicles .
Fig. 151 Unbe lted occupants in a vehicle heading for a
wall
Fig. 152 The vehicle crashes into the wall
The physical principles are simple. Both the
veh icle and the passengers possess energy
which varies w ith veh icle speed and body
weight . Engineers call this energy "kinetic en­
e rgy."
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 ene rgy increases 4 times!
Because the passengers of th is veh icle are not
using safety belts
c:::;, fig. 151, they will keep
mov ing at the same speed the vehicle was
mov ing just befo re the crash, unt il something
stops them - here, the wall ¢
fig. 152.
Safety belts 139
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 fo rces are even
highe r.
Peop le who do not use safety belts are also
not attached to their vehicle . In a frontal colli­
s ion they will also keep moving forward at the
speed their veh icle was travel ling just before
the crash . Of co urse, the laws of physics don't
just app ly to frontal collisions, they determine
what happens i n all k inds of a cc ident s and col­
li s 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 safety belts!

properly ¢
page 53, General recommenda­
t ions .
.,. Make sure the seatback of the rear seat
bench is in an upright pos ition and securely
latched in place before using the belt¢.&,.
.,. Hold the be lt by the tongue and pull it even ­
ly across the chest and pelvis ¢ .&, .

curely latched in t he buckle.
Automatic safety belt retractors
Every safety belt is equipped w ith an automat­
i c belt retracto r on the shoulder be lt. This fea­
ture locks the be lt whe n the belt is pulled out
fast, dur ing hard braking and i n an accident.
The belt may also lock when yo u drive up or
down a steep hill or throug h a sharp curve.
During normal driv ing the belt lets you move
freely.
Safety belt pretensioners
The sa fety belts are equipped with a be lt pre ­
tensioner that helps to tighten the safety be lt
and remove s lack when the pretensione r is ac ­
tivated ¢

Convertible locking retractor
Every safety belt except the one on the driver
seat is eq uipped w ith a convertib le loc king re­
tractor that
must be used when the safety
be lt is used to attach a child seat. Be su re to

.,& WARNING
Imprope rly positioned safety belts can
cause se rious injury in an accident
¢ page 14 2, Safety bel t posi tion.
- Safety belts offer opt imum protection
only when the seatback is upr ight and
be lts are properly posit ioned o n the
body .
- Always make sure that the rear seat
backrest to wh ich the center rear safety
be lt* is attached is securely latched
wheneve r the rea r center safety belt is
be ing used.
If th e bac krest is not secu re­
ly latched, the passenge r will move fo r­
ward with the ba ckr est dur ing s udden
brak ing, in a sudden maneuver and es pe­
cially in a crash.
- Never at tach the safety bel t to the buck­
le for ano ther seat. Attaching the belt to
the wron g buckle will reduce safety be lt
effectiveness and can cause serio us per­
sonal injury .
- A passenger who is not proper ly restrain­
ed can be seriously injured by the safety
be lt itself w hen it moves from the stron­
ger parts of the body into cr itical areas
like the abdomen .
- Always lock the conve rtible locking re­
tracto r when you are secu ring a child
seat in the vehicle ¢

Child restraints on the front seat - some
important things to know
.. Be sure to read the important information
and heed the WARNINGS for important de­
tai ls about children and Advanced Airbags
~page 173.
Even though your vehicle is equipped with an
Advanced Airbag System, make certain that
a ll chi ldren, especially those 12 years and
younger, always ride in the back seat properly
restra ined for their age and size. The airbag
on the passenger side makes the front seat a potentially dangerous place for a child to r ide .
The front seat is not the safest place fo r a
chi ld in a fo rward-facing chi ld seat. It can be a
very dange ro us p lace for an infant or a ch ild in
a rearward -facing seat.
The Advanced Airbag System i n your veh icle
h as been cert ified to comp ly with the require­
men ts of Uni ted States Federa l Mo to r Veh icle
Safety Standard 208 as applicable at the time
your vehicle was manufactured.
The Standard requires the front a irbag on the
passenger side to be turne d off ("sup­
p ressed") if a child up to about one year of
age restrained in one of the rear-facing or for­
ward -facing infant restraints listed in Federal
Motor Vehicle Safety Standard 208 with wh ich
the Advanced Airbag System in your vehicle
was certified has been installed on the front
passenger seat. For a listing of the child re­
straints that we re used to certify compliance
with the US Safety Standard ~
page 175.
The PASS ENGER AIR BAG OFF light in the in­
strument panel te lls you when the front Ad­
vanced A irbag on the passenger side has been
turned off by the e lectronic control u nit.
Each t ime you sw itch on the ignit ion, the
PAS­
SENGER AIR BAG OFF

few seconds a nd:
- will stay on if the front passenger seat is not
occup ied,
- will stay on if the electrical capacitance
measured by the capacitive passenger de­
tection system for the front passenge r seat
A irbag sys tem 149
equa ls the combined capacitance of an in­
fant up to about one year of age and one of
the rearwa rd-facing o r forward-fac ing ch ild
restraints listed in Federal Motor Vehicle
Safety Standard 208 with which the Ad­
vanced Airbag System in your ve hicle was
cert ified. Fo r a listing of the child restraints

-w ill stay on if t he re is a small ch ild or child
restrai nt on the front passenge r seat,
- w ill go off if the front passenger seat is oc­
cupied by an adult as registered by the ca­
pacitive passenger det ection sys tem
~ page 159, Monitoring the Advanced Air­
bag System.
T he PASSENGER AIR BAG OFF lig ht comes on
when e lec tric al capacitan ce registe red on the
fron t passenger seat is eq ua l to or less than
the combined capacitance of a typical 1 year ­
o ld infant and one of the rearward-facing or
f orward -facing child restraints listed in Feder­
al Motor Vehicle Safety Standard 208 with
which the Advanced Airbag System in your ve­
hicle was certified.
If the total e lectr ica l capacitance registered
on the front passenger seat is more than that
of a typical 1 year-old child but less than the
weight of a small adult, the front airbag on
the passenger side can deploy (the
PASSEN­
GER AIR BAG OFF
light does not come on).
If the
PASSENGER AIR BAG OFF light does
not come on, the front airbag on the passen­
ger side has not been turned off by the e lec­
tron ic cont ro l unit and ca n deploy if the con­
t rol unit senses an impact tha t mee ts the co n­
di tions s to red in its memo ry.
For example, th e airbag may deploy if:
- a small ch ild that is heav ier than a typical 1
year-old child is on the front passenger seat
(regard less of whether the child is in one of
the ch ild seats listed~
page 175), or
- a child who has outgrown child restraints is
on the front passenge r seat. .,,. •

150 Airbag sys te m
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light comes on in
the instrument cluster and stays on.
I f the front passenger airbag deploys, the
F ederal Standard requires the airbag to meet
the " low risk" deployment criteria to reduce
the r isk of injury through interaction with the
a irbag. "Low risk" deployment occurs in those
crashes that take place at lower decelerations
as defined in the electronic control unit
c::> page 160, PASSENGER AIR BAG OFF light.
A lways remember, a chi ld seat or infant carri­
er installed on the front seat may be struck
and knocked out of position by the rap idly in ­
flating passenger's a irbag in a frontal colli­
sion . The airbag could greatly reduce the ef­
fectiveness of the ch ild restraint and even se­
rio usly inju re the child during inflat ion.
For this reason, and because the back seat is
the safest place for chi ldren - when properly
restra ined accord ing to their age and size - we
strongly recommend that children always sit in the back seat
c::> page 173, Child Safety.
_& WARNING
-
A child in a rearward -facing child seat in ­
stalled on the front passenger seat will be
seriously injured and can be killed if the
front airbag inflates - even with an Ad­
vanced Airbag System.
- The inflating a irbag will hit the child seat
or infant carrier with great force and w ill
smash the ch ild seat and child against
the backrest, center armrest, door or roof.
- Always install rear-facing child seats on the rear seat.
- If you must install a rearward facing
child seat on the front passenge r seat
because of exceptiona l circumstances
and the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install the rear-f acing chi ld seat in a
rear seating position and have the ai rbag
system inspected by your Aud i dealer. -
Forward-facing child seats installed on
the front passenger's seat may interfere
with the deployment of the a irbag and
cause serious persona l injury to the
child.
_& WARNING
-If, i n except ional circumstances, you must
i nsta ll a forward-facing child restraint on
the front passenge r's sea t:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacture r fo r use on a fron t seat
with a passenger fron t and s ide a irbag.
- Never p ut the fo rward -facing child re­
s tra int up against or very near the instru­
men t panel.
- Always move the passenge r 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 installing
the forward-facing ch ild restra int . The
backrest must be ad justed to an upright
position.
-Make sure that the PASSENGER AIR BAG
OFF
li ght comes on and stays on all the
time whenever the ignition is switched on .
_& WARNING
-To reduce the risk of serious injury, make
sure that the
PASSENGER AIR BAG OFF
light w ill be displayed whenever a child re­
straint is installed on the front passenger
seat and the ignition is sw itche d on .
- If the
PASSENGER AIR BAG OFF light
does not s tay on, perform the checks de­
scribed
<> page 159, Monitoring the Ad­
vanced Airbag System.
- Ta ke the chi ld restraint off the front pas­
senger sea t and install it prope rly at one
of the rear seat positions i f the
PASSEN­
GER AIR BAG OFF
light does not stay on.
- Have the airbag system inspected by
your Aud i dea ler immediately.

Advanced front airbag system
Your veh icle is equipped w ith a front Advanced
Airbag System in comp liance with Un ited
States Federal Motor Vehicle Safety Standard 208 as applicable at the time your vehicle was
manufactured.
The front Advanced Airbag System supple­ ments the safety belts to provide add it iona l
protection for the driver's and front passeng­
e r's heads and upper bodies in frontal crashes.
The airbags inflate only in frontal impacts
when the vehicle dece le rat io n is high enough.
The front Advanced A irbag System for the
fro nt seat occupants is not a substitute for
your safety belts . Rather, it is part of the over­
all occupant rest raint system in your ve hicle.
A lways remember that the airbag system can
only help to pro tect you, if you are s itting up ­
righ t, wearing yo ur sa fety belt and wearing it
properly. This is why you and yo ur passengers
must always be properly restrained, not just
because the law requires you to be.
The Advanced Airbag System in your veh icle
h as been certified to meet the " low r isk" re­
q uir ements for 3 and 6 year-o ld children on
the passenger s ide and very small adu lts on
the dr iver side. The low risk deployment crite­
ria are intended to he lp reduce the risk of i n­
j ury through interaction with the front airbag
A irbag system 153
that can occur, for examp le, by being too
close to the steering wheel and instr ument
panel when the airbag inflates .
In add ition, the system has been cert ified to
comply with the "s uppression" requirements
of the Safety Standard, to turn off the front
airbag for in fants 12 months o ld and younger
who are rest rained on the front passenger
seat in child restraints that are listed in the
Standa rd
c> page 175, Child restraints and
Advanced front airbag system .
"Suppression" requires the front a irbag on the
passenger side to be turned off if:
- a child up to abo ut one year of age is re­
strained on the front passenger seat in one
of the rear-fac ing or forward -facing infant
restraints listed in Federal Motor Vehicle
Safety Standard 208 with which the Ad ­
vanced Airbag System in your ve hicle was
cert ified . Fo r a listing of the chi ld restraints

For 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 seats listed

-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.
If the front passenger airbag deploys, the Federal Standard requires the a irbag to meet
the "low risk" deployment criteria to help re­

Alwa ys rememb er: Even tho ugh your 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 i n the sect ions that follow
and be sure to heed a ll of the WARNINGS .
A WARNING
To reduce the risk of injury when an airbag
inf lates, 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 serious in juries 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
c':> page 147.
A WARNING
A child in a rearward -facing child seat in ­
stalled on the front passenger seat will be seriously injured and can be killed
if the
front airbag inflates - even w ith an Ad­
vanced Airbag System.
- Altho ugh the Advanced Airbag System in
your veh icle is designed to turn off the
front airbag when a rearward-facing
child restraint has been installed on the
front passenge r seat, nobody can abso­
lutely guarantee that dep loyment is im­
possible in all con ceivable s ituations that
may h appen dur ing the usefu l life of y our
veh icle .
- T he inflating airbag will h it the ch ild seat
or infant carrier wi th grea t force and will
smash the child seat and child against
the backrest, center armrest, door, or
roof.
- Always install rearward-facing chi ld re­
straints on the rear seat.
- If you must install a rearward fac ing
child seat on the front passenger seat
because of exceptional circumstances
and the
PASSENGER AIR BAG OFF light
does not come on and stay on, immed i­
ately insta ll the rear-facing child seat in a
rea r seat ing pos ition and have the airbag
system inspected by you r Audi dealer.
A WARNING
If, in except iona l circumstances, you must
i nsta ll a forward-facing child restraint on
the front passenge r's sea t:
- Always make sure the forward-facing
seat has been designed and ce rtified by
its manufacture r fo r u se on a fron t seat
with a passenger fron t and s ide a irbag .
- Never p ut the fo rward-facing child re­
straint up agains t or ve ry near the instru­
ment panel.
- Always move the p assenge r 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 installing
the forward-facing ch ild restra int. The
backrest must be ad justed to an upright
position.

-Always make sure that there is nothing
on the front passenger seat that will
cause the capacitive passenger detection
system in the seat to s ignal to the A irbag
System that the seat is occupied by a person when it is not, or to signal that it
is occupied by someone who is heavier
than the person actually s itting on the
seat . The presence of additiona l objects
cou ld cause the passenger front airbag
to be t urned on when it sho uld be off, or
cou ld cause the airbag to work in a way
that is different from the way it wou ld
have worked without the object on the
seat .
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
t ime whenever the ignition is switched
on.
Advanced Airbag System components
The front passenger seat in your vehicle has a
l ot of very important parts of the Advanced
Ai rbag System in it. These parts incl ude the
capacitive passenger detection system, wir ­
i n g, brackets, and more . The control unit
monitors the system o n the front passenger
seat when the ign ition is switched on and
turns the airbag indicator light on when a
malfunct ion in the one of the system compo­
nents is detected ¢
page 160. Because the
front passenger seat contains important parts
of the Advanced Airbag System, you must
t ake care to p reven t it from being damaged.
D amage to the seat may preven t the Ad­
vanced A irbag System for the front passenger
seat from doing its job in a crash .
The front Advanced Airbag System
consists of the following:
-Crash sensors in the front o f the veh icle that
measure vehicle acceleration/dece leration
to provide information to the Advanced Air­
bag System about the severity of the crash .
- An electronic co ntrol unit, with integrated
crash sensors for front and side impacts .
The contro l unit "decides" whether to fire
A irbag system 15 5
the front airbags based on the in format ion
received from the crash sensors. The contro l
unit also "decides" whether the safety be lt
pretens ioners sho uld be activated .
- An Advanced Airbag with gas generator and
contro l valve for the driver ins ide the steer­
ing wheel hub.
- An Advanced Airbag with gas gene rator and
contro l valve inside the instrument pane l for
the front passenger.
- A capacitive passenger detection system un­
derneath the front passenger seat cover.
This system measures the electrical capac i­
tance of the person in the seat. The informa­
tion registered is se nt cont inuously to the
el ectr onic contro l un it to regu late deploy­
ment of the front Advan ced A irbag on the
passenger side .
- An airbag monitoring system and ind icator
light in the instr ument cluster ¢
page 159.
-A sensor in each front seat registers the dis­
tance be twee n the respec tive seat a nd the
s teer ing whee l or inst rument p anel. The i n­
forma tion regis tered is sent cont inuo usly to
the electronic contro l unit to regulate de­
p loyment of the front Adv a need Airbags.
- The
PASSENGER AIR BAG OFF light comes
on and stays on in the center of the instr u­
ment panel ¢
page 160, fig. 164 and tells
you when the front Advanced Airbag on the passenger side has been turned off.
- A sensor in the safety belt latch for the driv­
er and for the front seat passenger that
senses whether that safety belt is latched or
not and transmits this information to the
electronic control un it .
.&_ WARNING
D amage to the front passe nger seat can
p revent the front air bag from wor king
properly.
- I mp roper repa ir or d isassembly of the

156 Airbag system
-Never remove the front passenger or
driver seat from the vehicle.
- Never remove the upholstery from the
front passenger seat.
- Never disassemble or remove parts from
the seat or disconnect wires from it.
- Never carry sharp objects in your pockets
or put them on the seat. The capacitive
passenger detection mat in the front
passenger seat will not function properly
if it is punctured .
- Never carry things on your lap or carry objects on the front passenger seat.
Such objects can influence the capaci­
tance registered by the capacitive pas ­
senger detection system, so that incor­
rect information is provided to the airbag
control unit.
- Never store items under the front pas­
senger seat. Parts of the Advanced Air­
bag System under the passenger seat
could be damaged, preventing them and
the airbag system from working proper­
ly.
- Never place seat covers or replacement upholstery that have not been specifical­
ly approved by Audi on the front seats.
- Seat covers can prevent the Advanced Airbag System from recognizing child re­
straints or occupants on the front pas­
senger seat and prevent the side airbag
in the seat backrest from deploying prop­
erly.
- If a seat heater has been retrofitted or
otherwise added to the front passenger
seat, never install any child restraint sys­
tem on this seat .
- Never use cushions, pillows, blankets, or similar items on the front passenger
seat. The additional layers prevent the
capacitive passenger detection system
from accurately measuring the capaci­
tance of the child safety seat and/or the
person on the seat and thus keep the Ad­
vanced Airbag System from working properly.
- Never place or use any electrical device
(such as a laptop, CD player, electronic games device
, power inverter or seat
heater for child seats) on the front pas­
senger seat if the device is connected to
the 12-volt socket or the cigarette light­
er socket . Such devices can influence the
capacitance registered by the capacitive passenger detection system, so that in­
correct information is provided to the air­
bag control unit.
- If you must use a child restraint on the
front passenger seat and the child re­
straint manufacturer's instructions re­
quire the use of a towel, foam cushion or
something else to properly position the
child restraint, make certain that the
PASSENGER AIR BAG OFF light comes
on and stays on whenever the child re­
straint is installed on the front passen­
ger seat.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install child restraint in a rear seat­
ing position and have the airbag system inspected by your Audi dealer.
,8. WARNING
If the front passenger seat gets wet, dry it
immediately.
- If liquid soaks into the front passenger
seat, this can keep the airbag system
from working properly and may, for in­
stance, deactivate the passenger frontal
airbag. If this happens, the
PASSENGER
AIR BAG OFF
light will come on and stay
on together with the airbag indicator light
fl in the instrument cluster .
- If liquid is pooled on the seat, but has
not soaked in, this may also keep the air­
bag system from working properly and
cause the passenger frontal airbag to be
enabled (turned on), even though there is a properly installed child restraint sys­
tem on the seat . Wet towels or other wet
things on the seat cushion can have the
same effect. If the front passenger fron­
tal airbag is turned on, the
PASSENGER
AIR BAG OFF
light light will go out.

How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
side airbags supplement the protection of­
fered by the front three -point safety be lts
with pretensioners and load limiters and the
adjustable head restra ints* to help reduce the
risk of injury in a wide range of acc ident and
crash situat ions . Be sure to read the impor­
tant information about safety and heed the
WARNINGS i n this chap ter .
Dep loyment of the Advanced Airbag System
and the activat ion of the safety be lt pre ten­
sioners depend on the dece lerat ion meas ured
by the c rash senso rs and registered by the

A WARNING
To reduce the risk of injury when an airbag
inf lates, a lways wear safety belts properly .
-If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, yo ur r isk of inj ury is much hig he r.
- You w ill also receive serious injuries and
cou ld eve n be killed if you are up against
the a irbag or too close to it when it in-

front airbags
Fi g. 16 3 In flated front airbags
Safety be lts are important to he lp keep front
seat occupants in the proper seated position
so that airbags can unfold properly and pro­
vide supplementa l protect ion in a frontal col­
li s ion.
The front airbags are des igned to provide ad­
ditional protection for the chest and face of
the driver and the front seat passenger when :
- safety belts are worn proper ly,
- t he seats have been positioned so that the
occupant is properly seated as far as poss i­
ble from the airbag,
- and for ad justab le head restra ints: the head
restraints have been properly adj usted .
Bec ause airbags infl ate in the bli nk of an eye
wi th great force, th ings you have on your lap
o r have p laced on the seat co uld become dan ­
gerous projectiles, and be p ushed into you if
the a irbag inf lates.
When an airbag deploys, fine dust is re le ased.
This is norma l and is not caused by a fi re in
the ve hicle . This dust is made up mostly of a
powder used to lubricate the airbags as they
deploy. It could irr itate skin .
It is important to remembe r that wh ile the
supplementa l airbag system is designed to re­
duce the like lihood of serious injur ies, other
i njur ies, for example swelling, bruis ing and
minor abrasions, can also happen when air-
bags inflate . A irbags do not protect the arms .,_

or the lower parts of the body. Front airbags
supp lement the three-point safety belts only
in some frontal collisions in which the vehicle
dece leration is high enough to deploy the air­
bags.
F ront airbag s will not d eplo y:
-if the ignition is switched off when a crash
occurs,
- in side collisions,
- in rear-end collisions,
- in ro llovers,
- when the crash deceleration measured by
the a irbag system is less than the minimum
t h reshold needed for airbag deployment as
registered by the electron ic control unit.
The f ront pa ssenger airbag also will n ot
deploy:
- when the front passenger seat is not occu­
pied,
- when the electrical capac itance measured by
the capacitive passenger detect io n system
for the front passenger seat indicates that
the passenger side fronta l airbag must be
switched off by the e lectronic control unit
(the
PA SSENGE R AIR B AG OFF light

and stays on).
A WARNING
Sitting in the wrong position can increase
the risk of serious injury in crashes.
- To reduce the r isk of injury when the air­
bags inflate, the driver and passengers
must always sit in an upright position,
must not lean against or place any part
of the ir body too close to the area where
the a irbags are located.
- Occupants who a re unbelted, out of posi­
t ion or too close to the airbag can be se­
riously injured by an airbag as it un folds
with great force in the blin k of an eye

A WARNING
A child in a rearward-facing child seat in­
stalled on the front passenger seat will be
-
seriously injured and can be killed if the
front airbag inflates -even w ith an Ad­
vanced Airbag System.
- The inflating airbag will hit the ch ild seat
or infant carrier with great force and will
smash the child seat and child against
the backrest, center armrest, door or
roof.
- Always install rear-fac ing ch ild seats on
the rear seat .
- If you must install a rearward fac ing
child seat on the front passenger seat because of exceptional circumstances
and the
PASSENGER AIR BAG OFF light
does not come on and stay on, immed i­
ately insta ll the rear-facing child seat in a
rea r seating pos ition and have the airbag
system inspected by yo ur Audi dealer.
A WARNING
c'-----
Objects between you and the airbag will
increase the r isk of injury in a crash by in­
terfering with the way the airbag unfolds
or by be ing p ushed into you as the airbag
inflates.
- Never hold things in yo ur hands or on
your lap when the veh icle is in use.
-
- Never transport items on or in the area
of the front passenger seat. Objects
could move into the area of the front air­ bags during braking or other sudden ma­
neuvers and become dangerous projec­
tiles that can cause ser ious perso nal in­
jury if the a irbags inflate.
- Never p lace or attach accesso ries o r oth­
er objects (such as cup holders, te le­
phone brac kets, large, heavy or bulky ob­
jects) on the doors, over o r near the area
marked "AIRBAG" on the steering whee l,
instr ument panel, seat bac krests or be­
tween those areas and yourself. These
objects could cause in jury in a crash, es­
pecially when the airbags inflate.
- Never recline the front passenger's seat to transport objects. Items can also move into the area of the s ide airbag or
the front airbag during braking or in a
