Safety belts
General notes
Always wear safety belts!
Wearing safety belts correctly saves lives!
T his chapter explains why safety belts are nec­
essary, how they work and how to adjust and
wear them correctly .
~ Read all the information that follows and
heed all of the instructions and WARNINGS.
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of serious
personal injury and death.
- Safety belts are the single most effective
means available to reduce the risk of se­
rious injury and death in automobile acci­
dents. For your protection and that of
your passengers, always correctly wear
safety belts when the vehicle is moving .
- Pregnant women, injured, or physically
impaired persons must also use safety
belts. Like all vehicle occupants, they are
more likely to be seriously injured if they
do not wear safety belts. The best way to
protect a fetus is to protect the mother -
throughout the entire pregnancy.
Number of seats
Your Audi has a total of five seating positions:
two in the front and three in the rear. Each
seating position has a safety belt .
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of serious
personal injury and death.
- Never strap more than one person, in­
cluding small children, into any belt. It is
especially dangerous to place a safety
belt over a child sitting on your lap.
- Never let more people ride in the vehicle
than there are safety belts available.
Safety belts 131
-Be sure everyone riding in the vehicle is
properly restrained with a separate safe­
ty belt or child restraint.
~ Safety belt warning light
Your vehicle has a warning system for the
driver and front seat passenger (on USA mod ­
els only) to remind you abou t the importance
of buckling-up.
Fig. 111 Safety bel t warn ing light in the instr ume nt
cl uster -enla rged
Before driving off, always:
~ Fasten your safety belt and make sure you
are wearing it properly.
~ Make sure that your passengers also buckle
up and properly wear their safety belts.
~ Protect children with a child restraint sys-
tem appropriate for the size and age .
The warning light . in the instrument clus­
ter lights up when the ignition is on as a re­
minder to fasten the safety belts . In addition,
you will hear a warning tone for a certain peri­
od of time .
Fasten your safety belt and make sure that
your passengers also properly put on their
safety belts.

Child restraints on the front seat - some
important things to know
~ Be sure to read the important informat ion
and heed the WARNINGS for important de­
ta ils about ch ild ren and Advanced Airbags
Qpage 166.
Even though your vehicle is equ ipped with an
Advanced Airbag System, make certain that
all c hildren, especially those 12 years and
younger, a lways ride in the back seat properly
restrained for their age and size . The airbag
on the passenger side makes the front seat a potentially dangerous place for a child to ride.
The front seat is not the safest place for a
child in a forward-facing child seat. It can be a
ve ry dangerous place for an infant or a ch ild in
a rearward-facing seat.
The Advanced Airbag System in your veh icle
has been certified to comply with the require­
ments of United States Federal Motor Veh icle
Safety Standard 208 as applicable at the time
your ve hicle was manufactured.
The Standard requires the front a irbag on the
passenger side to be turned off ("sup ­
p ressed") if a ch ild up to about one year of
age restra ined in one of the rear-facing o r fo r­
ward-facing infan t restra ints listed in Federal
M otor Vehicle Safety Standard 208 with w hich
the Advanced A irbag System in your vehicle
was certified has been installed on the front
passenger seat. Fo r a listing of the child re­
straints that were used to certify compliance
with the US Safety Standard

The PASSENGER AIR BAG OFF light in the in­
strument panel te lls you when the front Ad­
vanced Airbag on the passenger side has been turned off by the e lectronic control unit. E
ach time you switch on the ignition, the
PAS­
SENGER AIR BAG O FF
light will come on for a
few seconds and :
- w ill stay on if the front passenge r seat is not
occupied,
- w ill stay on if the e lec trica l ca pa citance
meas ured by the capacitive passenger de ­
tection system for the front passenger seat equa ls the combined capacitance of an in ­
fant up to about one year of age and one of
the rearward-facing or forward-fac ing ch ild
restraints listed in Federal Motor Vehicle
Safety Standard 208 with wh ich the Ad ­
vanced Airbag System in your vehicle was
cert ified . For a listing of the chi ld restraints
tha t were used to certify you r vehi cle's com­
p lia nce w it h t he U.S. Safety Standard
Q page 168.
-w ill stay on i f there is a small ch ild or child
restraint on the front passenge r seat,
- will go off if the front passenger seat is oc ­
cupied by an adult as registered by the ca ­
pacitive passenger de tection system
c::> page 152, Monitoring the Advanced Air·
bag System.
The PASSENGER AIR BAG OFF light comes on
when e lectrica l capacitance registered on the
front passenger seat is eq ua l to or less tha n
the comb ined capacitance of a typica l 1 year­
o ld infant and one of the rearward-facing or
forward-facing chi ld restraints listed in Feder­
al Motor Vehicle Safety Standard 208 with
wh ich the Advanced Airbag System in your ve­
hicle was certified.
If the total electr ica l capacitance registered
on the front passenger seat is more than that
of a typical 1 year -o ld child but less than the
weight of a small adult , the front airbag on
t h e 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 t he e lec­
t ro ni c cont ro l unit and can deploy if the con­
t ro l uni t se nses an impact tha t mee ts the con-
di tions stored in its memory .
1J1>

Fo r exa mple, the a irbag may depl oy if:
-a small child that is heavier than a typical 1
year-o ld child is on the front passe nger seat
(regardless of whether the child is in one of
the chi ld seats listed
page 168), or
- a ch ild who has outgrown child rest raints is
on the front passenger seat.
If the front passenger airbag is turned off, the
P ASS ENGER AIR B AG OFF light comes on in
the instrument cluster and stays on.
If the front passenger airbag deploys, the
Federal Standard requires the airbag to meet
the "low risk" deployment criter ia to reduce
the r isk of injury through interaction with the
airbag. "Low risk" deployment occurs in those
crashes that take place at lower decelerations
as defined in the electronic control unit
r::> page 153, PASSENGER AIR BAG OFF light.
Always remember, a chi ld seat or infant carri­
er insta lled on the front seat may be struck
and knocked out of position by the rapidly in­
flating passenger's airbag in a frontal colli­
sion. The airbag could greatly reduce the ef­
fectiveness of the child restraint and even se­
riously injure the child during inflat ion.
For this reason, and because the back seat is
the safest place for children - when properly
restrained according to their age and size - we
strongly recommend that children always sit
in the back seat
r::> page 166, Child Safety .
A WARNING
A child in a rearward-facing child seat in­
stalled on the front passenger seat will be
ser iously injured and can be killed if the
front airbag inflates -even with an Ad­
vanced Airbag System .
- T he inflating airbag will hit the child seat
or infant carrier with great force and wi ll
smash the child 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 passenger seat
-
A irbag system 143
because of exceptional circumstances
and the
PAS SENGER AIR BAG OFF light
does not come on and stay on, immed i­
ately install the rear-fac ing child seat in a
rear seat ing pos ition and have the airbag
system inspected by your A udi dealer.
- Forward-facing child seats installed on the front passenger's seat may interfere
with the dep loyment of the a irbag and
cause serious persona l injury to the
child.
A WARNING
If, in except iona l circumstances, you must
install a forward -facing child restraint on
the front passenger's seat:
- Always ma ke 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.
- Always move the passenge r seat into its
rea rmost pos ition in the seat's fore and
aft ad justment range, as far away from
the airbag as possible before installing
the forward-fac ing ch ild restra int. The
backrest must be adjusted to an upright
position.
- Make sure that the
PASSENGER AIR BAG
OFF
l ight comes on and stays on all the
time wheneve r the ig nit ion is switched
on.
A WARNING
To reduce the ri sk of ser ious injury, ma ke
sure that the
PASSENGER AIR BAG OFF
light w ill be displayed whenever a child re ­
straint is insta lled on the front passenger
seat and the ignition is switched on.
- If the PASSENGER AIR BAG OF F light
does not stay on, perform the checks de­
scribed

148 Airbag system
-Always make sure that there is nothing
on the front passenger seat that will
cause the capacitive passenger detection
system in the seat to signal to the Airbag
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 sitting on the
seat. The presence of additional objects
could cause the passenger front airbag
to be turned on when it should be off, or
could cause the airbag to work 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
OFF
light comes on and stays on all the
time whenever the ignition is switched on.
Advanced Airbag System components
The front passenger seat in your vehicle has a
lot of very important parts of the Advanced
Airbag System in it. These parts include the
capacitive passenger detection system, wir­
ing, brackets, and more. The control unit
monitors the system on the front passenger
seat when the ignition is switched on and
turns the airbag indicator light on when a
malfunction in the one of the system compo­
nents is detected
¢ page 153. Because the
front passenger seat contains important parts
of the Advanced Airbag System, you must
take care to prevent it from being damaged.
Damage to the seat may prevent the Ad­
vanced Airbag 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 of the vehicle that
measure vehicle acceleration/deceleration
to provide information to the Advanced Air­ bag System about the severity of the crash .
- An electronic control unit, with integrated
crash sensors for front and side impacts.
The control unit "decides" whether to fire the front
airbags based on the information
received from the crash sensors. The control
unit also "decides" whether the safety belt
pretensioners should be activated.
- An Advanced Airbag with gas generator for
the driver inside the steering wheel hub.
- An Advanced Airbag with gas generator in­
side the instrument panel for the front pas­
senger.
- A capacitive passenger detection system un­
derneath the front passenger seat cover.
This system measures the electrical capaci­ tance of the person in the seat. The informa­
tion registered is sent continuously to the
electronic control unit to regulate deploy­ ment of the front Advanced Airbag on the
passenger side.
- An airbag monitoring system and indicator
light in the instrument cluster
¢page 152 .
-A sensor in each front seat registers the dis­
tance between the respective seat and the steering wheel or instrument panel. The in­
formation registered is sent continuously to
the electronic control unit to regulate de­
ployment of the front Adv a need Airbags.
- The
PASSENGER AIR BAG OFF light comes
on and stays on in the center of the instru­
ment panel
¢ page 210 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 unit .
A WARNING
--
Damage to the front passenger seat can
prevent the front airbag from working
properly.
- Improper repair or disassembly of the
front passenger and driver seat will pre­
vent the Advanced Airbag System from
functioning properly.
- Repairs to the front passenger seat must
be performed by qualified and properly
trained workshop personnel.

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 no t deplo y:
- if the ignition is switched off when a crash
occurs,
- in side collisions,
- in rear-end collisions,
- in rollovers,
- when the crash deceleration measured by
the a irbag system is less than the m inimum
threshold needed for airbag deployment as
registered by the electronic control unit.
The f ront pas seng er airbag al so 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 frontal airbag must be switched off by the electronic control unit
(the
P AS SENGER A IR BA G OFF light
c:> page 153 and how they work comes on
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 posit ion,
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 unfolds
with great force in the blink of an eye
c:> page
142 .
A WARNING
A child in a rearward-facing child seat in­
stalled on the front passenger seat will be
-
A irbag system 15 1
seriously injured and can be killed if the
front airbag inflates -even w ith an Ad­
vanced A irbag 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
P A SSENGER AIR BAG OFF light
does not come on and stay on, immed i­
ately insta ll the rear-fac ing child seat in a
rear seating position and have the airbag
system inspected by your A udi dealer.
A WARNING
r---------
O b j e cts between you and the airbag will
increase the risk of injury in a crash by in­
terfering with the way the airbag unfolds
or by be ing pushed into you as the airbag
inflates.
- Never hold things in your 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 personal 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 b rac kets, large, heavy or bulky ob ­
jects) on the doors, over o r near the area
marked "AIRBAG" on the steering wheel,
instrument panel, seat backrests or be­
tween those areas and yourself . These
objects could cause injury 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 a irbag or
the front a irbag during braking or in a

sudden maneuver. Objects near the
air bags can become projectiles and cause
injury, particularly when t he s eat is re­
cl in ed .
- Never place or trans port objects on the
front passenger seat. Obj ects on the
front passenger seat could cause the ca­
pacitive sensor in the seat to s ignal to
airbag system that the seat is occupied
by a person when it in fa ct is not, o r th at
the person on the sea t is he avie r than he
or she actually is. The change in electric
capacitance because of such objects can
cause the passenger front airbag to be
t u rned on when it sho uld be off, or can
cause the airbag to work in a way that is
different from the way it wou ld have
worked w ithout objects on the seat.
- Always make sure that there is nothing
on the front passenge r seat that will
cause the capaci tive passenger detection
system in the s eat to s ignal to the A irbag
System that the seat is occupied by a
person when it is not, or to sign al that it
is occupied by someone who is heavier
than the person actually sitting on the seat . The prese nce of an object co uld
cause the passenger front a irbag to be
t u rned on when it sho uld be off, or co uld
cause the airbag to work in a way that is
differe nt from the way it wou ld have
worked w it h out the object on the seat.
