8_ 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 wi ll also receive serio us injuries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in­
flates - even with an Advanced Airbag

More important things to know about
front airbags
Fig . 167 Inflated front a irbags
Safety belts are important to help keep front
seat occupants in the proper seated pos ition
so that airbags can unfo ld prope rly and pro­
vide supplemental protection in a frontal co l­
lision .
The front airbags are designed to provide ad­ d itional protect ion for the chest and face of
the dr iver and the front seat passenger when :
- safety belts are worn properly, -
the seats have been positioned so that the
occupant is properly seated as far as possi­
b le from the airbag,
- and the head restraints have been properly
adjusted .
Bec ause airb ags infla te in the blin k of an eye
with great force, th ings you have on your lap
or have p laced on the seat co uld become dan ­
gerous pro jecti les, and be p ushed into you if
the a irbag inf lates .
When an airbag deploys, fine dust is re leased .
This is no rma l and is not caused by a fire i n
the vehicle . 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
injur ies, for example swelling, bruising and
minor abrasions, can also happen when air­
bags inflate . A irbags do not protect the arms
o r the lower parts of the body . Front a irbags
supplement the three-point safety bel ts only
i n some fronta l co llisions in which the vehicle
de celeration is h igh enough to deploy the air­
bags .
Front airbags will not deploy:
-if the ignition is sw itched off when a c rash
o ccu rs,
- in side co llisions,
- in rear-end collisions,
- in rollovers,
- when the crash deceleration measu red by
the airbag system is less than the min imum
threshold needed for a irbag deployment as
reg istered by the electronic contro l unit .
The front pa ssenge r airbag also will not
deploy:
- when the front passenger seat is not occu­
pied,
- when the weight on the front passenger
seat as sensed by the Advanced Airbag Sys­
tem ind icates that the front a irbag on the
passenger side has to be turned off by the ..,.

Important safety instructions on the
side airbag system
Airbags are only supplemental restraints. Al­
ways properly wear safety belts and ride in a
proper seating position.
There is a lot that you and your passengers
must know and act accordingly to help the
safety belts and airbags do their job to pro­
vide supplemental protection .
A WARNING
An inflating side airbag can cause serious
or fatal injury. Improperly wearing safety
belts and improper seating positions in­
crease the risk of serious personal injury
and death whenever a vehicle is being
used .
- In order to reduce the risk of injury when
the supplemental side airbag inflates:
-Always sit in an upright position and
never lean against the area where the
supplemental side airbag is located.
- Never let a child or anyone else rest
their head against the side trim panel
in the area where the supplemental
side airbag inflates.
- Always make sure that safety belts are worn correctly,
- Do not let anyone sitting in the front
seat put their hand or any other parts
of their body out of the window.
- 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
deploy.
- 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.
Airbag system 173
- Objects between you and the airbag can
increase the risk of injury in an accident
by interfering with the way the airbag
unfolds or by being pushed into you as
the airbag inflates.
- Never place or attach accessories or
other objects (such as cup holders, tel­
ephone brackets, or even large, bulky
objects) on the doors, over or near the
area marked "AIRBAG" on the seat backrests .
- Such objects and accessories can be­ come dangerous projectiles and cause
injury when the supplemental side air­
bag deploys.
- Never carry any objects or pets in the
deployment space between them and
the airbags or allow children or other passengers to travel in this position .
- Always use the built -in coat hooks only
for lightweight clothing . Never leave any
heavy or sharp-edged objects in the
pockets that may interfere with side air­
bag deployment and can cause personal
injury in an accident.
- Always prevent the side airbags from be­
ing damaged by heavy objects knocking
against or hitting the sides of the seat­
backs.
- The airbag system can only be triggered
once. If the airbag has been triggered,
the system must be replaced by an au­
thorized Audi dealership.
- Damage (cracks, deep scratches etc .) to
the original seat covers or to the seam in
the area of the side airbag module must always be repaired immediately by an au­
thorized Audi dealer .
- If children are seated improperly, their
risk of injury increases in the case of an
accident ~
page 177, Child Safety.
-Never attempt to modify any compo­
nents of the airbag system in any way .
- In a side collision, side airbags will not
function properly if sensors cannot cor­ rectly measure increasing air pressure in-
side the doors when air escapes through .,.. •

Side curtain airbags
Description of side curtain airbags
The side curtain airbag system can provide
supplemental protection to properly restrain ­
ed occupants.
Fi g. 1 73 Side curtain a irbags, d river 's side: s ide curta in
a ir bag location
The s ide curtain airbags are located o n both
sides of the interior above the front and rea r
side windows
c:.> fig. 173 . They are ident ified
by the word "AIRBAG" on the windshield
frame and the center roof p illar.
The s ide curtain airbag system supp lements
the safety belts and can help to reduce the risk of injury for occupants' heads and upper
torso o n the side of the vehicle tha t is struc k in a side collision
. The side curtain airbag in­
flates in side impacts and only when the vehi­ cle acceleration registered by the control un it
is h igh enough . If this rate is below the refer­
ence value programmed into the control unit,
the side airbags will not be triggered, even
t h ough the car may be bad ly damaged as a re­
su lt of the co llision .
It is not possib le to de­
fine an airbag triggering range that will cover every possib le ang le of impact, s ince the cir­
cumstances will vary cons iderably between
one collision and another. Important factors
include, for example, the nature (hard or soft)
of the impacting object, the angle of impact,
vehicle speed, etc .
c:,, page 175, How side cur­
tain airbags work .
Aside from their normal safety function, safe­
ty belts work to help keep the driver or front
passenger in position in the event of a colli­
sion so that the side curtain airbags can pro­
vide protection .
The airbag system is not a substit ute for your
safety belt . Rather, it is part of the overall oc­
cupant restraint system in your vehicle. Al­
ways remember that the a irbag system can
only help to protect you if you are wear ing
you r saf ety belt and wearing it properly . This
is anothe r reason why yo u should always wear
yo ur safe ty belts, no t just because the law re ­
quires yo u to do soc:.>
page 145, General
notes .
It is important to remember that w hile the
s ide cur tain airbag system is designed to help
reduce the likelihood of ser ious injur ies, other
injuries, for example, swelling, bruising, and
minor ab rasions can also be associated with
these a irbags upon dep loyment. Remember
too, these airbags will deploy only once and
only in certain kinds of accidents -your safety
belts are always there to offe r protection .
The s ide curtain a irbag system basic ally
cons ists of:
- The e lectronic control module and external
side impact sensors
- The side curtain airbags above the front and
rear s ide windows

-The airbag indicator light in the instrument
pane l
The airbag system is moni to red ele ct ro ni ca lly
t o make certain it is fu nct ion ing properly a t all
times. Each time you switch on the ignition,
the airbag system indicator light wi ll come on
for a few seconds (se lf d iagnost ics) .
The side curtain airbag is not activated:
-if the ignition is switched off,
- i n s ide collisions wh en the acceleration
measu red by the sensor is too low,
- i n rear-end collisions,
- in rollovers.
A WARNING
-
- Safety belts and the a irbag system will
only p rov ide p rotection when occ upants
are in t he p roper seat ing posit io n
c::> page 58, General recommendations.
- If the airbag indicato r light c::> page 18
comes whe n the vehicle is be ing used,
have the system inspected immediately
by you r auth o rized Audi dea le r. I t is pos ­
sible that the airbag will inflate when it
is not supposed to, or w ill not inflate
when it sho uld.
How side curtain airbags work
Side curtain airbags con work together with
side airbags to help reduce the risk of head
and upper torso injuries for occupants who
are properly res trained.

When the system is t riggered, the side curta in
airbag is filled with propellant gas and breaks
through a seam above the front and rear side
w indows identified by the AIRBAG labe l. In or­
der to he lp provide this additional protection,
the side curtain airbag must inflate within the
blink of an eye at very high speed and with
great force. The side curtain a irbag could in ­
jure you if your seating pos it io n is not prope r
or upright or if items are located in the area
whe re the supplemen tal side curta in a irbag
infl ates. This applies espe cially to ch ildren

ploys . Th is is qui te no rma l and does not mean

expansion range of a side curtain airbag
can dangerously interfere with its func­
tion. A deploying head airbag develops enough force to catapult any piece of
add-on component out of its path of in­
flation and into the passenger compart­
ment. An occupant hit by such a projec­
t il e can suffer serious injury or death
9 page 295, Technical Modifications.
- Do not swivel the sun visors to the side if
yo u have any objects clipped onto them
(for example pens) . If the ai rbag should
deploy, you could be inj ured by these ob­
jects.
- Use the built -in coat hoo ks only for light­
weight clothing. Never leave any heavy or
sharp-edged objects in the poc kets that
may interfere with airbag deployment
and can cause personal injury in an acci­
dent .
- Never use hangers to hang clothing from
the hooks.
- Only use factory-installed sun shades or,
in the case of shades installed after the
vehicle leaves the factory, only Audi roll­ up sunsc reens may be used

- Always s it in proper seating position and
wea r safety belts while t raveling so that
the side curtain airbags can help provide
pro tection.
- T he ai rbag system can only be t rigge red
once.
If the a irbag has been triggered,
the system m ust be replaced by an au­
thorized Aud i dealer o r qualified work ­
shop .
- Alw ays have work involving the side cur­
tain airbag system, removal and installa­
tion of the airbag components, or other
repa irs performed by a qualified dealer­
ship. Otherwise the airbag system may
not work cor rectly.
- Never attempt to modify any compo­ nents of the airbag system in anyway.

Child safety seats
Infant seats
Babies and infants up to about one year old
and 20 lbs. or 9 kg need special rearward -fac ­
ing child restraints that support the back,
neck and head in a crash.
Fig . 176 Sche matic overv iew: rearward-fac ing infant
seat, properly installed o n the rear seat
.,. When using the vehicle safety belt to install
a ch ild safety seat, you must first activate
the convertible locking retracto r on the
safety be lt to prevent the child safety seat
from moving
¢ page 187 or install the seat
using the LA T CH attachments.
.,. Push the child safety seat down with your
full weight to get the safety belt rea lly tight
so that the seat cannot move forward or
sideways more than one inch (2.5 cm).
.,. Secure unused safety belts on the rear seat
¢page 182.
Infants up to about one year (20 lbs. or 9 kg)
are best protected in special infan t carriers
and child safety seats designed for their age
group . Many experts believe that infants and
small children should ride only in spec ial re­
straints in which the ch ild faces the back of
the vehicle. These infant seats support the ba­
by's back, neck and head in a crash ¢
fig. 176.
The airbag on the passenger side makes the
front seat a po tentially dangerous place for a
child to r ide . The front seat is not the safest
p lace for a child in a forward -facing child seat.
It is a very dangerous p lace for an infant or a
l arger ch ild in a rearward-facing seat.
Child Safety 183
A WARNING
Not using a child safety seat, using t he
wrong child safety seat or improperly in ­
stall ing a ch ild restraint increases the risk
of ser ious personal injury and death in a
crash.
- Never install rear-facing child safety
seats or infant ca rr ie rs on the front pas­
senger seat -even with an Advanced Air ­
bag Sys tem. A ch ild will be ser iously in­
jured and ca n be killed when the inflat ­
ing airbag hits the child safety seat or in­
fant carrier with great force and smashes the child safety seat and child against
the backrest, center armrest, door or
roof ¢

_& WARNING
If exceptional circumstances require the
use of a forward-facing child restraint on
the front passenger's seat, the child's safe­
ty and well-being require that the follow­
ing special precautions be taken:
- Make sure the forward-facing seat has
been designed and certified by its manu­
facturer for use on a front seat with a
passenger front and side airbag.
- Always follow the manufacturer's in­
struct ions provided with the child safety
seat or infant carrier.
- Always move the front passenger seat in­
to the rearmost position of the passen­
ger seat's fore and aft adjustment range,
and as far away from the airbag as possi­ ble before installing the child restraint.
-A lways make sure that nothing prevents
the front passenger's seat from being
moved to the rearmost position in its
fore and aft adjustment range.
- Always make sure the backrest is in an
upright position.
- Make sure that the
PASSENGER AIR BAG

light comes on and stays on all the
time whenever the ignition is switched
on.
- If the light does not stay on, perform the
checks

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) toll.

The vehicle's safety belts alone will not fit
most children until they are at least 4
ft. 9 in.
(57 inches/1.45 meters) tall and weigh about
80 lbs. (36 kg). Booster seats raise these chil­
dren up so that the safety belt will pass prop ­
erly 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 re­ strain a child on a booster seat.
.. The shoulder belt must lie as close to the
center 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 tighten if necessary .
.. If you must transport an older child in a
booster seat on the front passenger seat,
you can use the safety belt height adjust­ ment to help adjust the shoulder portion
properly.
