Advanced front airbag system and children
Your vehicle is equipped with an "Advanced Airbag System" in
compliance with United States Federal Motor Vehicle Sa fety Stan ­
dard (FMVSS) 208 as applicab le at the time your vehicle was manu ­
factured .
Controls and equip­
ment Safety first Vehicle operation
The Advanced Airbag system in your vehicle has been certified to
meet the " low -risk" requirements for 3 and 6 yea r- old child ren on
the passenger side and small adu lts on the driver side. The low risk
deployment c rite ria are intended to reduce the risk of injury th rough
interaction with the airbag that can occur, for example, by being too
close to the steering whee l and instrument panel when the airbag
in flates . In add ition, the system has been cert ified to comply with
the "suppression" requirements of the Safety Standard, 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 listed in the
Standard.
Even though your vehic le is equipped with an Advanced Airbag
system, all ch ildren, especially those 12 years and younger, should
a lways ride in the back seat proper ly restrained for the ir age and
s ize . The a irbag on the passenger side makes the front seat a poten­
tially dangerous p lace for a chi ld to r ide. The front seat is not the
safest place for a chi ld in a forward -facing child safety seat. It can be
a very dangerous place for an infant or a larger chi ld 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 p resence
of an infant or chi ld in a chi ld restraint on the front passenger seat
using the weight -sensing mat in the seat cushion 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 t otal weight of the ch ild and the
child safety seat and a chi ld blanket on the front passenger seat. The
weight on the front passenge r 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 seat. The weight of a child
restraint and its "footprint" vary for different kinds of child .,

restraints and for the different models of the same kind of child
restraint offered by child restraint manufacturers.
The weight ranges for the individual types, makes and models of child restraints that the NHTSA has specified in the Safety Standard
together with the weight ranges of typical infants and typical 1 year­
old child have been stored in the control unit of the Advanced
Airbag System. When a child restraint is being used on the front passenger seat with a typical 1 year-old child, the Advanced Airbag
System compares the weight measured by the weight sensing mat
with the information stored in the electronic control unit.
The electronic control unit also registers the tension on the front
passenger safety belt. The tension on the safety belt for the front
passenger seat will be different for an adult who is properly using
the safety belt as compared to the tension on the belt when it is used to attach a child restraint to the seat. The sensor below the
latch for the safety belt for the front seat passenger measures the
tension on the belt . The input from this sensor is then used with the
weight to "decide", whether there is a child restraint with a typical 1
year-old child on the front passenger seat and whether or not the airbag must be turned off.•
Child restraints and Advanced Airbags
Regardless of the child restraint that you use, make sure that it has
been certified to meet United States Federal Motor Vehicle Safety
Standards and has been certified by its manufacturer for use with
an airbag. Always be sure that the child restraint is properly
installed at one of the rear seating positions. If in exceptional
circumstances you must use it on the front passenger seat, carefully read all of the information on child safety and Advanced Airbags
and heed all of the applicable WARNINGS. Make certain that the
child restraint is correctly recognized by the weight -sensing mat
inside the front passenger seat, that the front passenger airbag is
turned off and that the airbag status is always correctly signaled by
the
PASSENGER AIR BAG OFF light. Many types and models of child restraints have been available over
the years, new models are introduced regularly incorporating new
and improved designs and older models are taken out of produc­
tion. Child restraints are not standardized. Child restraints of the
same type typically have different weights and sizes and different
'footprints,' the size and shape of the bottom of the child restraint
that sits on the seat, when they are installed on a vehicle seat. These
differences make it virtually impossible to certify compliance with
the requirements for advanced airbags with each and every child
restraint that has ever been sold in the past or will be sold over the
course of the useful life of your vehicle.
For this reason, the United States National Highway Traffic Safety
Administration has published a list of specific type, makes and
models of child restraints that must be used to certify compliance
of the Advanced Airbag System in your vehicle with the suppression
requirements of Federal Motor Vehicle Safety Standard 208. These
child restraints are:

is switched on.
• Take the child restraint off the front passenger seat and install
it properly at one of the rear seat positions if the PASSENGER AIR
BAG OFF light does not stay on.
• Have the airbag system inspected by your authorized Audi
dealer immediately .

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 responsible for the safety of every
­
body in the vehicle, especially children:
- Always use the right child safety seat for each child and
always use it properly~
page 195.
-Always carefully follow the child safety seat manufac­
turer's instructions on how to route the safety belt prop­
erly through the child safety seat.
- When using the vehicle safety belt to install a child safety
seat , you must first activate the convertible locking
retractor on the safety belt to prevent the child safety
seat from moving~
page 200.
-Push the child 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 being used to tie the child safety
seat to the front passenger seat, make sure that it is not
so tight that it causes the weight-sensing mat to
measure more weight than is actually on the seat.
Always remember: Even though your vehicle is equipped with an
Advanced Airbag system, all children, especially those 12 years and
younger, should always ride in the back seat properly restrained for
their age and size. •

& WARNING
Not using a child safety seat, using the wrong child safety seat or
improperly installing a child restraint increases the risk of serious
personal injury and death.
• All vehicle occupants and especially children must always be
restrained properly whenever riding in a vehicle .
- An unrestrained or improperly restrained child can be injured or killed by being thrown against the inside of the vehicle or by
being ejected from it during a sudden maneuver or impact.
- An unrestrained or improperly restrained child is at much
greater risk of injury or death by being struck by an inflating
airbag.
• Commercially available child safety seats are required to
comply with U .S. Federal Motor Vehicle Safety Standard (FMVSSI
213 (in Canada CMVSS 2131.
-When buying a child restraint , select one that fits your child
and the vehicle.
- Only use child restraint systems that fully contact the flat
portion of the seat cushion . The child restraint must not tip or
lean to either side . Audi does not recommend using child safety
seats that rest on legs or tube-like frames. They do not provide
adequate contact with the seat .
- Always heed all legal requirements pertaining to the installa ­
tion and use of child safety seats and carefully follow the
instructions provided by the manufacturer of the seat you are
using .
• Never allow children under 57 inches (1 .5 meters) to wear a
normal safety belt. They must always be restrained by a proper
child restraint system. Otherwise, they could sustain injuries to
the abdomen and neck areas during sudden braking maneuvers or
accidents.
• Never let more than one child occupy a child safety seat .
& WARNING (continued)
• Never let babies or older children ride in a vehicle while sitting
on the lap of another passenger.
- Holding a child in your arms is never a substitute for a child
restraint system .
- The strongest person could not hold the child with the forces
that exist in an accident. The child will strike the interior of the
vehicle and can also be struck by the passenger.
- The child and the passenger can also injure each another in
an accident.
• Never install rear-facing child safety seats or infant carriers on
the front passenger seat. A child will be seriously injured and can be killed when the passenger airbag inflates - even with an
Advanced Airbag System.
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest, center arm rest, door or roof .
• Always install rear -facing child safety seats or infant carriers on
the rear seat .
• Forward-facing child safety seats installed on the front
passenger's seat can interfere with the airbag when it inflates and
cause serious injury to the child . Always install forward -facing
child safety seats on the rear seat.
• If exceptional circumstances require the use of a forward ­
facing child restraint on the front passenger's seat, the child's
safety and well -being require that the following special precau ­
tions be taken :
- 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 carefully follow the manufacturer 's instructions
provided with the child safety seat or carrier .

& WARNING (continued)
-Always move the front passenger seat into the rearmost
position of the passenger seat's fore and aft adjustment range,
and as far away from the airbag as possible before installing
the child restraint.
- Always 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 that the backrest is in the upright posi­
tion.
• Always buckle the child safety seat firmly in place even if a
child is not sitting in it. A loose child safety seat can fly around
during a sudden stop or in a collision.
• Always read and heed all WARNINGS whenever using a child
restrained in a vehicle is being used=>
page 159, "Safety belts",
=>
page 168, "Airbag system" and=> page 190, "Child Safety".
& WARNING
To reduce the risk of serious injury, make sure that the PASSENGER
AIR BAG OFF light comes on and stays on whenever a child
restraint is installed on the front passenger seat and the ignition
is switched on.
• Take the child restraint off the front passenger seat and install
it properly at one of the rear seat positions if the PASSENGER AIR
BAG OFF light does not stay on.
• Have the airbag system inspected by your authorized Audi
dealer immediately. •
Safety first
Child Safety
Child safety seats
Infant seats
Babies and infants up to about one year old and 22 lbs or
10 kg need special rearward-facing child restraints that
support the back, neck and head in a crash.
Fig. 179 Rearward­
facing infant seat,
properly installed on
the rear seat
-When using the vehicle safety belt to install a child safety
seat, you must first activate the convertible locking
retractor on the safety belt to prevent the child safety
seat from moving
=> page 200 or install the seat using
the LATCH attachments.
- Push the child 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).
Infants up to about one year (22 lbs. or 10 kg) are best protected in
special infant carriers and child safety sea ts designed for their age
group. Many experts believe that infants and small children should
ride only in special restraints in which the child faces the back of the
vehicle. These infant seats support the baby's back, neck and head
in a crash. These child safety seats must never be used in the front
seat because of the risk of serious injury or death should the airbag
deploy in a crash => fig. 179. .,,.

Not using a child safety seat, using the wrong child safety seat or
improperly installing a child restraint increases the risk of serious
personal injury and death in a crash.
• Never install rear-facing child safety seats or infant carriers on
the front passenger seat -even with an Advanced Airbag System.
A child will be seriously injured and can be killed when the
inflating airbag hits the child safety seat or infant carrier with
great force and smashes the child safety seat and child against the
backrest, center arm rest, or door=>

the front seat -some important things to know".
• Always install rear-facing child safety seats or infant carriers on
the rear seat.
• Never install a rear-facing child restraint
in the forward-facing
direction. Such restraints are designed for the special needs of
infants and very small children and cannot protect them properly
if the seat is forward-facing.
• If you must install a rearward facing
child safety seat on the
front passenger seat because of 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 airbag system inspected by your
Audi dealer.

Booster seats
Properly used booster seats can help protect children
weighing between about 40 lbs . and 80 lbs. (18 kg and 36
kg) who are less than
4 ft. 9 in. tall.
Fig . 181 Rear seat:
child properly
restrained
in a booster
seat
The vehicle's safety belts alone will not fit most children
until they are at least 4 ft. 9 in. tall and weigh about 80 lbs.
(36 kg). Booster seats raise these children up so that the
safety belt will pass properly 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 restrain a child on a booster
seat.
- Always position the shoulder portion of the safety belt
midway over the child's shoulder.
- Always make sure that the shoulder portion of the safety belt never rests against or across the child's neck.
- Always make sure that the child can properly wear the lap portion of the belt low across the thighs or pelvis and
never over the stomach or abdomen .
Children up to about 40 lbs (18 kg) are best protected in child safety
seats designed for their age and weight. Experts say that the skel ­
etal structure, particularly the pelvis, of these children is not fully
developed, and they should not use the vehicle safety belts
=> page 1981 fig . 181.
Children who weigh more than 40 lbs. (18 kg) may generally use the
available three point combination lap and shoulder belts when they
sit on an appropriate booster seat . Be sure the booster seat meets
all applicable safety standards .
Booster seats raise the seating position of the child and reposition
both the lap and shoulder parts of the safety belt so that they pass
across the child's body in the right places. The routing of the belt
over the child's body is very important for the child's protection.
This applies whenever a child uses the vehicle's safety belts, even
when the child is big enough to use them without a booster seat. Children age 12 and under should
always ride in the rear seat.
Children should not ride in the front seat unless no other seating
position is available because crash statistics show that children are
better protected in the rear seat.
In a crash, airbags must inflate within a blink of an eye and with
considerable force . In order to do its job, the airbag needs room to
inflate so that it will be there to protect the occupant as the occu ­
pant moves forward into the airbag.
A vehicle occupant including a child who is out of position and too close to the airbag gets in the way of an inflating airbag. When an
occupant is too close, he or she will be struck violently and will
receive serious or possibly even fatal injury .
In order for the airbag to offer protection, it is important that all
vehicle occupants, especially any children, who must be in the front
seat in exceptional circumstances, be properly restrained and as far
away from the airbag as possible. By keeping room between the
child's or other occupant's body and the front of the passenger
compartment, the airbag can inflate fully and completely and
provide supplemental protection in certain frontal crashes . ._
