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 ..,.

Monitoring the
Advanced Airbag System
Cl! (USA models)/!f (Canada models)
Airbag monitoring indicator light
Two separate indicators monitor the function
of the Advanced Airbag System: the airbag
monitoring indicator light and the
PASSEN­
GER AIR BAG OFF
light.
The Advanced Airbag System (including the
electronic control unit, sensor circuits and sys­
tem wiring) is monitored continuously to
make sure that it is functioning properly
whenever the ignition is on. Each time you
switch on the ignition, the airbag monitoring
indicator light
I (USA mode ls)/ fll (Canada
models) will come on for a few seconds (self
d iagnost ics).
The system must be inspected when the
indicator light
I (USA models)/E,I
(Canada models):
-does not come on when the ignition is
switched on,
- does not go out a few seconds after you have switched on the ignition, or
- comes on while driving.
If an airbag system malfunct ion is dete cted,
the indicator light will first start flashing to
catch the driver's attention and then stay on
continuously to serve as a constant reminder
to have the system inspected immediately.
If a malfunction occurs that turns the front
airbag on the passenger side
off, the PASSEN­
GER AIR BAG OFF
light will come on and stay
on whenever the ignition is on.
A WARNING
An airbag system that is not functioning
properly cannot provide supplemental pro­
tection in a frontal crash.
- If the airbag indicator light
c::> page 18
comes when the vehicle is be ing used,
have the system inspected immediate ly
by your authorized Audi dealer. It is pos- sible
that the airbag will inflate when it
is not supposed to, or will not inflate
when it should.

The PASSENGER AIR BAG OFF light will come
on and stay on to tell you when the front Ad­
vanced Airbag on the passenger s ide has been
turned
off by the electron ic control unit. Each
t ime you switch on the ign it ion, the
PASSEN­

light will flash for a few
seconds and:
- will stay on if the front passenger seat is not
occupied,
- will stay on if there is a small ch ild or child
restraint on the front passenger seat,
- w ill go out if the front passenger seat is oc ­
cupied by an adult as registered by the
weight-sensing mat.
The
PASSENGER AIR BAG OFF light must
come on and stay on
if the ignition is on and
- a car bed has been installed on the front seat, or
- a rearward-facing child restraint has been
installed on the front passenger seat, or
- a forward-facing child restraint has been in-
stalled on the front passenger seat, or
liJI,

-the weight registered on the front passen­
ger seat is equa l to or less than the com­
bined weight of a typical 1 year -old restrain­
ed in one of the rear-fac ing or forward­
facing infant restraints listed in Federal Mo­
tor Vehicle Safety Standard 208 with which
the Advanced Airbag System in your vehicle
was certified .
If the front passenger seat is not occupied,
the front airbag will not deploy, and the
PAS­
SENGER AIR BAG OFF
light will stay on . Nev­
er insta ll a rearward-facing child restra int on
the front passenger seat, the safest place for
a child in any kind of child restraint is at one
of the seating positions on the rear seat

If the PASSENGER AIR BAG OFF light comes
on
when one of the conditions listed above is
met, be sure to check the light regularly to
make certa in that the
PASSENGER AIR BAG
OFF
light stays on cont inuously whenever the
ignit ion is on. If the
PASSENGER AIR BAG
OFF light does not appear on and does not
stay on all the time, stop as soon as it is safe
to do so and
- react ivate the system by switching the igni­
t ion off and then switch ing it on again;
- remove and reinstall the child restraint .
Make sure that the child restraint is properly
installed and that the safety belt for the
front passenger seat has been correct ly
routed through the child rest raint as descri­
bed in the child restrai nt manufactu rer's i n­
str ucti ons;
- make sure that the conver tible locking fea­
ture on the safety belt for the front passen­
ger seat has been activated and that the
safety belt has been pulled tight. The belt
must not be loose or have loops of slack so
that the sensor below the safety belt latch
on the seat can do its job
¢ page 187.
- make sure that things that may increase the
weight of the chi ld and child seat are not be­
ing transported on the front passenger seat;

-make sure that the safety belt tension sen ­
sor is not blocked. Shake the safety belt
latch on the front passenger seatback and
forth;
- If a strap or tether is being used to tie the
child seat to the front passenger seat, make
sure that it is not so t ight that it causes the
weight-sensing mat to measure more
weight than is actually on the seat .
If the PASSENGER AIR BAG OFF light still
does not come on
and does not stay on con­
ti nu ously (when the ignition is switched on),
- take the child restraint off the front passen -
ger seat and install it properly at one of the
rear seat positions. Have the airbag system
inspected by your Audi dealer immed iately.
- move the ch ild to a rear seat position and
make sure that the child is properly restra in­
ed in a ch ild restra int that is appropriate for
its size and age .
The
PASSENGER AIR BAG OFF light should
NOT come on when t he ignition is on and an
adult is sitting in a proper seating position on
the front passenger seat. If the PASSENGER
AIR BAG OFF
light comes on and stays on or
flashes fo r about 5 seconds wh ile d riving, un­
der these circumstances , make sure that:
- the adult on the front passenge r seat is
prope rly seated on the center of the seat
cushion with his or her back up against the
backrest and the backrest is not re clin ed

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.

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

Important safety instructions on the
side curtain 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 do to he lp the safety belts and
airbags do their job to provide supplemental
protection .
A WARNING
Improperly wearing safety belts and im­
p roper seating positions increase the risk
of ser ious personal injury and death when­
eve r a vehicle is being used .
- Never let occupants place any parts of thei r bod ies in the area from which the

178 Child Safety
-Always install rear-facing child safety
seats on the rear seat.
- If you must install a rearward facing
child safety seat on the front passenger
seat in exceptional circumstances and
the
PASSENGER AIR BAG OFF light does
not come on and stay on, immediately
install the rear-facing child safety seat in
a rear seating position and have the air­
bag system inspected immediately by
your Audi dealer.
_& WARNING
If, in exceptional circumstances, you must
install a forward-facing child restraint on
the front passenger's seat:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag.
- Always follow the manufacturer's in­
structions provided with the child safety
seat or carrier.
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible before installing
the child restraint. The backrest must be
adjusted to an upright position .
- Always make sure that the
PASSENGER
AIR BAG OFF
light comes on and stays
on all the time whenever the ignition is
switched on.
(D Tips
Always replace child restraints that were
installed in a vehicle during a crash. Dam­
age to a child restraint that is not visible
could cause it to fail in another collision
situation.
Advanced front airbag system and children
Your vehicle is equipped with a front "Ad­
vanced Airbag System" in compliance with United States Federal Motor Vehicle Safety Standard (FMVSS) 208 as applicable at the
time your vehicle was manufactured.
The Advanced Airbag system in your vehicle
has been certified to meet the "low-risk" re­
quirements for 3- and 6-year old children on
the passenger side and small adults on th e
driver side. The low ris k deployment criteria
are intended to reduce the risk of injury
through interact ion with the airbag t hat can
occur, for example, by being too close to the
steering wheel and instrument panel when
the airbag inflates . In addition, the system
has been certified to comply with the "sup­
pression" requirements of the Safety Stand­
ard, to turn off the front airbag for infants up
to 12 months who are restrained on the front
passenger seat in child restraints that are list­
ed in the Standard.
Even though your vehicle is equipped with an
Advanced Airbag system , all children, espe­
cially those 12 years and younger, should al­
ways ride in the back seat properly restrained
for their age and size. The airbag on the pas­
senger 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 for­
ward-facing child safety seat. It can be a very
dangerous place for an infant or a larger child
in a rearward-facing seat .
Advanced Airbags and the weight­
sensing mat in the front seat
The Advanced Airbag System in your vehicle
detects the presence of an infant or child in a
child restraint on the front passenger seat us­
ing the weight-sensing mat in the seat cush ­
ion and the sensor below the safety belt latch
on the front passenger seat that measures the
tension on the safety belt.
The weight -sensing mat measures total
weight of the child and the child safety seat
and a child blanket on the front passenger
seat. The weight on the front passenger seat
is related to the design of the child restraint
and its "footprint", the size and shape of the
bottom of the child restraint as it sits on the .,..

Important safety instructions for using
child safety seats
Correct use of child safety seats substantially
reduces the risk of injury in an accident!
As the driver, you are responsib le for the safe­
ty of everybody in the veh icle, especially ch il­
dren:
.. Always use the right chi ld safety seat for
each child and always use it properly
¢page 183.
.. Always carefully follow the child safety seat
manufacturer's instruct ions on how to route
the safety belt properly through the ch ild
safety seat .
.. When using the vehicle safety belt to install
a child safety seat, you m ust first a ctivate
the convertib le locking retractor on the
safety belt to prevent the child safety seat
from moving
¢ page 187.
.. Push the ch ild safety seat down with your
full weight to get the safety belt really tight so that the seat cannot move forward or
sideways more than one inch (2 .5 cm) .
.,. If a strap or tether is be ing used to tie the
child safety seat to the front passenger
seat , m ake sure tha t it is not so tight that i t
causes the weight-sensing ma t to measure
more weight than is act ually on the seat.
.. Sec ure unused safety belts on the rear seat
¢ page 182.
Always remember : Even though your vehicle is
equipped with an Advanced Airbag system, all
children, especially those 12 years and young­
er, shou ld always r ide in the back seat proper-
ly restrained for their age and size . .,.

_& 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
OFF
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.
