2009 AUDI TT COUPE child restraint

__________________________________________________ A_ i_ r _b _a...; g::- s_ y=--- s_t _e _m __ lllll
Whe n a person is detected on the front passenger seat, weighing
more than the to tal weight of a child t hat is about 1 year old
restrained in one of the rear-facing or forward -facing infant
restraints (listed in Federa l Motor Vehicle Safety Standard 208 with
which the Advanced Airbag System in your vehicle was certified), the front airbag on the passenger side may or may not deploy .
The
PA SSENGER AIR BAG OFF light comes on when the e lectronic
control unit detects a total weight on the front passenger seat that
requires the front a irbag to be turned off . If the
PA SSENGER AIR BAG
O FF
light does not come on, the front airbag on the passenger side
has not been tu rned off by the contro l u nit and can dep loy if the
control unit senses an impact that meets the conditions stored in its
memory .
I f the total weight on the front passenger seat is more than that o f
a typical
1 year -old, but less than the we ight of a small adult, the
front airbag on the passenger side may dep loy (the
PA SS ENGER AIR
BAG OFF
l ight does not come on).
For example , the airbag may deploy if :
• a small ch ild that is heavier than a typ ical 1 year-o ld child is on
the front passenger seat (regardless of whether the child is in one
of the child sa fety seats listed ~ page
159),
• a child who has outgrown child res traints is on the front
passenger seat.
I f the front passenger airbag is turned off, the
PASSENGER AIR BAG
O FF
light in the cen ter of the instrument panel wi ll co me on and stay
on .
T he front airbag on the passenge r side may
not deploy (the
PASS ENGER AIR BAG OFF light does not illuminate and stay lit) if:
• a small adult or teenager is on the front passenger seat
• a passenger who is not sitting upright with their back against a
non -reclined backrest with their feet on the vehicle floor in front of
the seat is on the front passenger seat.
I f the front passenger airbag dep loys, the Federal Standard requires
the airbag t o meet the "low risk" deployment criteria to help reduce
Controls and equip­ ment Safety first Vehicle operation the risk of injury through interaction with the airbag
. "Low risk"
dep loyment occurs in those crashes that ta ke place at l ower decel ­
erations as defined in the electronic control unit~ page
146.
Alway s remembe r: Even though your vehicle is equipped with
Advanced Airbags, the safes t place for chi ldren is properly
restrained on the back seat. Please be sure to read the important
informat ion in t he sections tha t follow a nd be sure to heed a ll of the
WARNINGS.
& WARNING
To reduce the risk of injury when an airbag inflates , always wear
s afety belts prope rly.
• If you are unrestrained , leaning forward , sitt ing s ideways or out
of position in any w ay, your risk of injury i s mu ch higher .
• You will al so receive se riou s injurie s and could even be killed if
you are up against the airbag or too clo se t o it when it inflate s -
even with an Advanced Airbag => page 135 .
& WARNING
A child in a rearward -facing child safety seat in stalled on the front
pa ssenge r seat will be ser iou sly injured and can be killed if the
front airb ag inflate s -even with an Advanced Airbag System .
• Although the Advan ced Airbag S ystem in your vehicle is
de signed to turn off the front airbag when a rearward -fa cing child
restraint h as been in stalled on the front pa ssenger seat , nobod y
c an ab solutely guarantee that deployment i s impo ssible in all
c onceivable situations that may happen during the useful life of
your vehicle .
• The inflating airbag will hit the ch ild s afety seat or inf ant
c arrier with great force and will smash the chi ld safety seat and
c hild ag ains t the ba ckre st, door , or roof .
• Always in stall rearward -facing child re straint s in the back seat ....

& WARNING (continued)
• 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.
& 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.
• Never put the forward-facing child restraint up against or very
near the instrument panel.
• 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 forward-facing child
restraint . The backrest must be adjusted to 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. •
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, brackets, and more. The func­
tion of the system in the front passenger seat is checked by the elec ­
tronic control unit when the ignition is on. The control unit monitors
the Advanced Airbag System and turns the airbag indicator light on
when a malfunction in the system components is detected. The
function of the airbag indicator light is described in greater detail below
. 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
Advanced Airbag 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
Airbag 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 inside the instrument
panel for the front passenger.
• A weight-sensing mat under the upholstery padding of the front
passenger seat cushion that measures the total weight on the seat.
The information registered is sent continuously to the electronic
control unit to regulate deployment of the front Advanced Airbag on
the passenger side.
• An airbag monitoring system and indicator light in the instru ­
ment cluster ~
page 146.
• The PASSENGER AIR BAG OFF light comes on and stays on in the
center of the instrument panel~
page 147, fig. 113 and tells you
when the front Advanced Airbag on the passenger side has been
turned off.
• A sensor below the safety belt latch for the front seat passenger
to measure the tension on the safety belt. The tension on the safety
belt and the weight registered by the weight -sensing mat help the
control unit "decide" whether the front airbag for the front ..

passeng er seat shou ld be turn ed off or not~ page 137, "Ch ild
restr aint s o n the fro nt seat - some impor tant thin gs to know".
• A sensor in the safety belt latch fo r the d rive r and for the front
s e at pass enger th at s enses wh ether th at safe ty belt i s la tch ed o r not
and transmits this information to the e lectronic contro l unit.
& 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 prevent the Advanced Airbag System from func ­
tioning properly .
• Repairs to the front passenger seat must be performed by qual ­
ified and properly trained workshop personnel .
• Never remove the front passenger or driver seat from the
vehicle.
• Never remove the upholstery from the front passenger seat .
• Never disassemble or remove parts from the seat or disconnect
wires from it.
• Never carry sharp objects in your pockets or place them on the
seat . If the weight-sensing mat in the passenger seat is punctured
it cannot work properly.
• Never carry things on your lap or carry objects on the
passenger seat . Such items can increase the weight registered by
the weight-sensing mat and send the wrong information to the
airbag control unit .
• Never store items under the front passenger seat . Parts of the
Advanced Airbag System under the passenger seat could be damaged , preventing them and the airbag system from working
properly.
• Never place seat covers or replacement upholstery that have
not been specifically approved by Audi on the front seats.
Controls and equip­ ment Safety first
Vehicle operation
& WARNING (continued)
• Seat covers can prevent the Advanced Airbag System from
recognizing child restraints or occupants on the front passenger
seat and prevent the side airbag in the seat backrest from
deploying properly.
• Never use cushions, pillows, blankets or similar items on the
front passenger seat. The additional padding will prevent the
weight-sensing mat in the seat from accurately registering the
child restraint or person on the seat and prevent the Advanced
Airbag System from functioning properly .
• If you must use a child restraint on the front passenger seat
and the child restraint manufa cturer's instructions require the use
of a towel , foam cushion or something else to properly position
the child restraint, make certain that the PASSENGER AIR BAG OFF
light comes on and stays on whenever the child restraint is
installed on the front passenger seat.
• If the PASSENGER AIR BAG OFF light does not come on and stay
on , immediately install child restraint in a rear seating position
and have the airbag system inspected by your Audi dealer. •
How the Advanced Airbag System
components
work together
The front Advanced Airbag System and the side airbags suppl ement
the protection offe red by t he front t hree -point safety bel ts with
pretens ioners and load limiters and the ad justable head restraints
to help reduce the risk of in jury in a wide range of accident and
c ras h situati ons. Be sure to read t he impo rtant inf ormatio n abou t
safety and heed the WARNI NGS in th is chapter.
D ep loym ent of the A dva nce d Ai rbag Sy stem and the activati on of
th e safety be lt pretension ers depend on the decel eration measur ed
b y the c ra s h sens ors and regis te re d by th e electr onic control unit.
C rash severity depends on speed and decel eration as we ll as t he
mass and s tiff ness of the veh ic le or object in vo lved in the crash.

When the electronic control unit registers a low severity crash and
th e safety belt is being used, the airbag will not deploy. If the safety
belt is not being used, the first stage deploys, followed by the
second stage after a much later time in the crash sequence.
If the electronic contro l unit registers a crash of medium severity,
the first stage of the airbag deploys followed by the second stage at
a much later time in the crash sequence -regardless of whether the
safety belt is being used or not . In higher severity crashes as regis­
tered by the e lectronic contro l unit, both the first and second stages
deploy almost at the same time.
On the passenger side, regardless of safety belt use, the airbag will
be turned off if the weight on the passenger seat is less than the
amount programmed in the electronic control unit . The front airbag
on the passenger side will also be turned off if one of the child
safety seats that has been certified under Federal Motor Vehicle
Safety Standard 208 has been recognized on the seat. The
PASSENGER AIR BAG OFF light comes on and stays on to tel l you
when the front Advanced Airbag on the passenger side has been
turned off~
page 137, "Child restraints on the front seat -some
important things to know".
& WARNING
To reduce the risk of injury when an airbag inflates, always wear
safety belts properly .
• If you are unrestrained , leaning forward , sitting sideways or out
of position in any way, your risk of injury is much higher .
• You will also receive serious injuries and could even be killed if
you are up against the airbag or too close to it when it inflates -
even with an Advanced Airbag~

More important things to knovv about front
airbags
Fig . 112 Inflated front
airbags
Safety belts are important to help keep front seat occupants in the
proper seated position so that airbags can unfold properly and
provide supp lemental protection in a fronta l collision.
The front airbags are designed to provide additional protection for
the chest and face of the driver and the front seat passenger when:
• safety be lts are worn properly,
• the seats have been positioned so that the occupant is properly
seated as far as possible from the airbag,
• and the head restraints have been properly adjusted.
Because airbags inflate in the blink of an eye with great force, things
you have on your lap or have placed on the seat cou ld become
dangerous projectiles, and be pushed into you if the airbag inflates .
When an airbag deploys, fine dust is released. This is normal and is
not caused by a fire in the vehic le. This dust is made up most ly of a
powder used to lubricate the airbags as they deploy. It could irritate
skin.
It is important to remember that while the supplemental airbag
system is designed to reduce the likelihood of serious injuries, other
injuries, for example swelling, bruising and minor abrasions, can
also happen when airbags inflate . Airbags do not protect the arms ._,

Child Safety
Important things to know
Introduction
The rear seat is generally the safes t place in a collision.
The p hysica l pr inciples of what happens when you r veh ic le is in a
crash apply also to children=>
page 127, "What happens to occu ­
p a nts not wearing safety bel ts?" . Bu t un like adults and teenagers,
their musc les and bones are not fully developed. In many respects
children a re a t greater ris k of serious inj ury in cras hes than a dults .
B ecause chi ldren's bodies a re no t fully deve loped, they require
restraint systems especial ly designed for their size, weight, and
body structu re. Ma ny countries and al l sta tes of the U nited States
and provinces of Canada have laws requiring the use of approved
chil d restraint sys te m s for infa nts and smal l children .
I n a frontal crash at a speed of 20 -35 mph (30 -56 km/h) the forces
ac ting on a 13-pou nd (6 kg) infant wi ll be mo re than 20 times the
weight of the child. This means the weight of the child would
suddenly be more than 260 pounds ( 120 kg). Under these condi ­
t ions, only an appropriate child restraint proper ly used can reduce
the risk of serious injury. Child restraints, like adult safety belts,
must be use d properly t o be eff ective. Use d impro perly, they can
increase the risk of serious injury in an accident.
Co nsul t the c hild safety seat man ufacture r's ins truc tions to be su re
the seat is right for your child's size=>
page 160, "Important safety
instructions for using child safety seats" . Please be sure to read and
heed a ll of the important information and WARNI NGS about child
safety, Advanced Airbags, and the insta llation of child restraints in
this chapter.
T here is a lot you need to know about the Advanced Airbags in your
veh ic le and how they work whe n inf an ts and ch ild ren in c hild
restraints are on the front passenger seat. Because of the large
Controls and equip­ ment Safety first Vehicle operation
amoun
t of important informat ion, we cannot repeat it all here. We
urge you to read the detai led information in this owner's manua l
about a irbags and the Advanced Airbag Sys tem in your ve hic le and
the very important information about transporting children on the
fr ont passenger sea t. Please b e sure to hee d th e WAR NINGS -th ey
are extreme ly important for your safety and the safety of your
p asse ngers, es pecia lly inf ant s and s mall ch ildren .
& WARNING
• Accident statistics have shown that children are generally safer
in the rear seat area than in the front seating position . Always
restrain any child age 12 and under in the rear.
• All vehicle o ccupants and especially children must be
restrained properly whenever riding in a vehicle . An unrestrained
or improperly restrained child could be injured by striking the inte­
rior or by being ejected from the vehicle during a sudden
maneuver o r impact . An unrestrained or improperly restrained
c hild is also at greater risk of injury or death through conta ct with
an inflating a irbag .
• A suitable child restraint properly installed and used at one of
the rear seating positions provides the highest degree of protec­
tion for infants and small children in most accident situations .
& WARNING
Children on the front seat of any car even with Advanced Airb ags
c an be seriously injured or even killed when an airbag inflates . A
child in a rearward -fa cing child safety seat installed on the front
pas senger seat will be seriously injured and can be killed if the
front airbag inflates.
• The inflating airbag will hit the ch ild safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest or door. •

Advanced front airbag system and children
Your vehicle is equipped with an "Advanced Airbag System" in
complia nce with United States Federa l Motor Vehicle Safety Stan ­
dard (FMVSS) 208 as applicable at the time your vehicle was manu ­
factu red. T
he Advanced Airbag system in your vehicle has been certified to
meet the " low -risk" requirements for 3 and 6 year -old chi ldren on
the passenger side and smal l 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 "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
S tandard.
Even though your vehicle is equipped with an Advanced Airbag
system, all ch ildren, especially those 12 years and younger, should
always ride in the back seat properly restrained for their age and
size . The airbag on the passenger side makes the front seat a poten­
tially dangerous p lace for a child to ride. The front seat is not the
safest p lace for a child in a forward -facing child safety seat. It can be
a very dangerous p lace for an infant or a larger ch ild 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 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 total weight of the chi ld 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 seat . The weight of a child
restraint and its "footprint" vary for different kinds of child ..,.
