rearmost position in the seat's fore and
aft adjustment range, as far away from
the a irbag as poss ible, before installing
the forward-facing child restraint. The backrest must be adjusted to an upr ight
posit io n.

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
weight-sensing mat, sensors, wiring, brack­
ets, and more. The function of the system in
the front passenger seat is checked by the
electronic control un it when the ign it ion is on .
The control unit mon itors the Advanced Air­
bag System and turns the airbag indicator
l ight on whe n a malfunction in the system
components is de tected. The function of the
ai rbag indicator light is described in greater
detai l be low . Because the front passenger
seat contains important parts of the Ad­
vanced A irbag System, you must take care to
prevent it from be ing damaged. Damage to
the seat may prevent the Advanced Airbag for
the front passenger seat from doing its job in
a crash .
The front Advanced Airb ag System
con sis ts of the following:
- Crash sensors in the front of the veh icle that
measure veh icle acceleration/deceleration
to provide information to the Advanced Air­
bag System about the seve rity of the c rash.
- An electron ic co ntro l unit, w ith integ rated
crash sensors for fron t and side impacts.
T he contro l unit "dec ides " whether to fire
the front airbags based on the information received from the crash sensors . The contro l unit also "decides" whether the sa
fety be lt
pretensioners shou ld be activated.
- An Advanced Airbag with gas generato r and
contro l valve for the driver inside the steer­
ing wheel h ub.
- An Advanced Airbag with gas gene rator and
contro l valve inside the instrument panel for
the front passenger .
- A weight -sensing mat under the upho lstery
padding of the front passenger seat cushion
that measures the total weight on the seat.
The informat ion registered is sent continu­
ously to the electronic control unit to regu­ late deployment of the front Advanced Air­
bag on the passenger side.
- An airbag monitoring system and indicator
light in the instrument cluster~
page 161 .
-A sensor in each front seat registers the dis­
tance betwee n the respective seat a nd the
steer ing whee l o r inst rument panel. The in­
formation registered is sent cont inuous ly to
t he ele ctron ic contro l uni t to regula te de­
p loyment of the front Adva nced A irbags .
- The
PASSENGER AIR BAG OFF light comes
on and st ays on in the center of the instr u­
ment p anel
~page 162, fig. 168 and t ells
you when the front Advanced Airbag on the
passenger side has been turned off .
- A sensor below the safety be lt latch for the
front seat passenger to measure the tension
on t he safety be lt . The tension on the safety
be lt and the weight registered by the
weight-sensing mat he lp the control unit
"decide" whether the front airbag for the
front passenger seat should be turned off or not
~ page 153, Child restraints on the
front seat -some important things to
know.
- A sensor in the safety belt latch fo r the driv­
er and fo r the fro nt seat passenger that
senses whether that safety bel t is latched or
no t and transmi ts this information to t he
electronic control unit.
A WARNING ~ -
Damage to the front passenger seat can
prevent the front airbag from work ing
properly.

-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
Child Safety 175
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 the driver side. The low risk deployment criteria
are intended to reduce the risk of injury
through interaction with the airbag that 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 si ze. 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 ..,.
