2017 AUDI TT ROADSTER warning

Airbag syste m
the system inspected immediately by your
authorized Audi dealer. It is possible that
the airbag will inflate when it is not sup­
posed to, or will not inflate when it should.
A WARNING
If the front airbag inflates, a child without a
child restra int, or in a rearward-facing child
safety seat, or in a forward-facing child re­
straint that has not been properly installed
w ill be seriously injured and can be killed.
- If you must install a rearward-fac ing child
seat on the front passenger seat because of
exceptional c ircumstances and the
PA SSEN ­
G ER AIR BAG OFF,;;
light does not appear
and stay on, have the airbag system inspect­
ed by your Audi dealer.
- If, in exceptional circumstances, you must
install a forward-facing chi ld restraint on
the front passenger seat, always move the
seat into its rearmost pos ition in the seat's
fore and aft adjustment range, as far away
from the airbag as possible. The backrest
must be adjusted to an upright posit ion.
Make s ure that the PASSENGER AI R BAG
OFF ,;;

t ime whenever the ignition is switched on.
A WARNING
If the PAS SENGER AIR BAG OFF~; light does
not go out when an adult is s itting on the
front passenger seat afte r taking the steps
described above, have the airbag system in­
spected by your Audi dealer before transport­
ing anyone on the front passenger seat.
(D Tips
If the capacitive passenger detection system
determines that the front passenger seat is
empty, the frontal airbag on the passenger
side w ill be turned off, and the
PA SSENGER
AIR BA G OFF ~;
light will stay on.
Repair, care and disposal of the airbags
Parts of the a irbag system are installed at many
d ifferent places on your Aud i. Instal ling, remov-
210
ing, servicing or repairing a part in an area of the
vehicle can damage a part of an airbag system
and prevent that system from work ing properly
i n a coll is ion.
There are some important things you have to know to make sure that the effectiveness of the
system will not be impaired and that discarded
components do not cause injury or pollute the
environment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal injury
and death by preventing an airbag from de­
p loying when needed or deploy ing an a irbag
unexpectedly:
-
- Never cover, obstruct, or change the steer­
ing wheel ho rn pad or airbag cover or the in­
strumen t panel or modify them in any way.
- Never attach any objects such as cup ho lde rs
or telephone mountings to the surfaces cov­
ering the a irbag un its.
- For cleaning the horn pad or instr ument
panel, use only a soft, dry doth or one mois­
tened w ith plain water. Solvents or cleaners
could damage the airbag cover or change
the st iffness or strength of the material so
that the airbag cannot deploy and protect proper ly.
- Never repair, ad just, or change any parts of
the airbag system.
- All work on the steering wheel, inst rument
panel, front seats or e lectr ica l system (in­
cluding the installation of audio equ ipment,
cellular te lephones and CB radios, etc.)
m ust be perfo rmed by a qualified techn ician
who has the training and spec ial equipment
necessary.
- For any work on the airbag system, we
strong ly recommend tha t you see you r au­
thori zed A udi dealer or qualified wo rkshop.
- Never modify the front bumper or pa rts of
the vehicle body.
- Always make sure that the side a irbag can
inflate w ithout interfe rence:

-Never install seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
Audi.
- Never use additional seat cushions that
cover the areas where the side airbags in­
flate.
- Damage to the original seat covers or to
the seam in the area of the side airbag module must always be repaired immedi­
ately by an authorized Audi dealer.
- The airbag system can deploy only once. Af­
ter an airbag has been deployed, it must be
replaced with new replacement parts de­
signed and approved especially for your
Audi model version. Replacement of com­ plete airbag systems or airbag components
must be performed by qualified workshops
only. Make sure that any airbag service ac­
tion is entered in your Audi Warranty
&
Maintenance booklet under AIRBAG RE­
PLACEMENT RECORD.
- For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechnic circuit interrupter.
- Work on the pyrotechnic circuit interrupt­
er must only be performed by a qualified
technicians who have the experience, in­
formation and special tools necessary to
perform the work safely.
- If the vehicle or the circuit interrupter is
scrapped, all applicable safety precautions must be followed.
@ For the sake of the environment
Undeployed airbag modules and pretension­
ers might be classified as Perchlorate Materi­
al -special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlo­
rate. When the vehicle or parts of the re­
straint system including airbag modules and
safety belts with pretensioners are scrapped,
all applicable laws and regulations must be
observed. Your authorized Audi dealer is fa­
miliar with these requirements and we recom­
mend that you have your dealer perform this
service for you.
Airbag system
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash. For example, using tire-rim
combinations not approved by Audi, lowering the
vehicle, changing the stiffness of the suspension, including the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic control unit. Some suspension changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in which it would not deploy if
the changes had not been made. Other kinds of
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy­ ing when it should.
A WARNING
-Changing the vehicle's suspension including use of unapproved tire-rim combinations can
change Advanced Airbag performance and in­
crease the risk of serious personal injury in a
crash.
- Never install suspension components that
do not have the same performance charac­
teristics as the components originally instal­
led on your vehicle.
- Never use tire-rim combinations that have
not been approved by Audi.

Airbag system
Knee airbags
Description of knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front seat
occupants.
Fig. 167 Driver's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering wheel¢
fig. 167, the
airbag for the passenger is at about the same
height in the instrument panel underneath the
glove compartment.
The knee airbag offers additional protection to
the driver's and passenger's knees and upper and
lower thigh areas and supplements the protec­
tion provided by the safety belts.
If the front airbags deploy, the knee airbags also
deploy in frontal collisions when the deployment
threshold stored in the control unit is met
¢ page 205, More important things to know
about front airbags.
In addition to their normal safety function, safe­
ty belts help keep the driver or front passenger in
position in a frontal collision so that the airbags
can prov ide supplemental protection.
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overall occu­
pant restraint system in your vehicle. Always re­
member that the airbag system can only help to
protect you if you are wearing your safety belt
and wearing it properly . This is why you should
always wear your safety belt, not just because
the law requires you to do so ¢
page 189, Gener­
al notes.
212
Remember too, airbags will deploy on ly once and
on ly in certain kinds of accidents -your safety
belts are always there to offer protection in those
accidents in which airbags are not supposed to
deploy or when they have already deployed, for
example when your vehicle strikes or is struck by
another after the first collision .
This is just one of the reasons why an airbag is
not a substitute for the safety belt . The airbag
system works most effectively when used with
the safety belts. Therefore, always wear your
safety belts correctly.
It is important to remember that while the sup­
plemental knee airbag system is designed to re­
duce the likelihood of serious injuries, other inju­
ries, for example, swelling, bruising and minor
abras ions and friction burns can also occur when
an airbag inflates.
The knee airbag system basically consists of:
-The electronic control module
- Two inflatable airbags (airbag and gas genera-
tor), one for the driver and one for the front
passenger
- The airbag warning light in the instrument clus-
ter
The knee airbag system will not deploy:
-when the ignition is switched off
- in frontal collisions when the decelerat ion
measured by the control unit is too low
- in side collisions
- in rear-end co llisions
- in rollovers
- in the event of a system malfunction (warning/
ind icator light is on) ¢
page 14 .
&_ WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
the proper seating position ¢
page 205.
-If the airbag ind icator light¢ page 14
comes when the vehicle is being used, have
the system inspected immediately by your
authorized Audi dealer.
It is possible that
the airbag will inflate when it is not sup ­
posed to, or wi ll not inflate when it should.

How knee airbags work
The risk of injury to the leg area can be reduced
by fully inflated kn ee airbags.
Fig . 168 Inflated airbags protecting in a fronta l collision
The knee airbag system has been designed so
that the airbags for the driver and front passen­ ger deploy in certain but not all frontal collisions .
If the front airbags dep loy, the knee ai rbags also
deploy in fronta l co llisions when the dep loyment
threshold stored in the contro l unit is met.
When the sys tem dep loys, the airbags fill with a
propellan t gas, and inf late between the lowe r
part of the instrument panel and the driver and
the lower pa rt of the instrument panel and the
front passenger ¢
page 205, fig. 165.
Although they are not a soft pi llow, they can
"c ushion" the impact and in this way they can
he lp to reduce the risk of injury to the lower ex­
tremities.
All of this ta kes place in t he b lin k of an eye, so
fast that many people don't even realize that the
airbags have dep loyed . The airbags also inflate
with a great deal of force and it is important for
occupant safety that nothing should be in their
way when they deploy .
F u lly inflated airbags in combination with proper­
ly worn safety belts slow down and limit the oc­
cupant 's forward movement and help to reduce
the r isk of injury.
Airb ag sys tem
Important safety instructions on the knee
airbag system
Airbags are only supplemental restraints . Always
wear safety belts correctly and ride in a proper
seating position .
There is a lot that you and yo ur passenger must
know and do to help the safety belts and ai rbags
to provide supp lemental protect ion.
A WARNING ~
An inflat ing knee a irbag can cause se rious in-
jury. Wearing safety be lts incorrectly and im­
proper seating positions increase the risk of
serious personal injury and death whenever a
vehicle is being used.
- The knee airbag system cannot protect yo u
proper ly if yo u are seated too close to any of
the airbag locations. When adjusting t heir
seat pos itions, it is important that both the
driver and the front passenger keep their
uppe r bodies and knees at the fo llow ing
m inim um safe d istan ces:
- at least 10 in (25 cm) between the chest
and t he steering wheel/instrument panel.
- at least 4 in (10 cm) between the knees
and t he lower part of the instrument pan­
el.
- The risk of personal inj ury increases if you
lean forward or to the side, or if the seat is
improperly positioned and you are not wear­
ing your safety belt. The risk increases even
more should the airbag deploy .
- Always make sure that the knee a irbag can
inflate w ithout interference. Objects be­
tween you and the airbag can increase the risk of injury in an accident by inte rfe ring
wit h the way the airbag deploys or by bei ng
pushed into yo u as the ai rbag deploys.
- Never let anybody, especially children or
anima ls r ide in the footwell in front of the
passenger seat. If the airbag deploys, this
can result in serious or fatal i njuries .
- Never carry objects of any kind in the foot­
well a rea in front of the driver's or pas­
senger's seat. Bulky objects (shopp ing
bags, fo r example) ca n in terfere with or
~
213

Airbag system
prevent proper deployment of the airbag.
Small objects can be thrown through the
vehicle if the airbag deploys and injure you
or your passenger .
- Make sure there are no cracks, deep scratch­
es or other damage in the area of the instru­
ment panel where the knee airbags are lo­
cated.
- If children a re incorrect ly seated, their risk
of injury increases in a collision

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
F ig. 169 Side airbag locat ion in t he drive r's seat
The side airbags are located in the sides of the
front seat backrests
c::> fig. 169 facing the doors .
They are identified by the word "AIRBAG".
The side airbags installed for the front seating
positions have been designed and certified to
help reduce the risk of injury that can be caused
by airbags when they inflate, particularly when
the occupant sitting next to it is not seated prop­
erly. The side airbag for the front passenger seat
can be used with properly installed child re­
straints. Please be sure to read the important in­
formation and warnings whenever using a child
restraint in a vehicle: Safety belts
c::> page 189,
Airbag system c::>page 196, Child safety
c::> page 218 .
The side airbag system basically consists of:
- the electronic control modu le and external side
impact sensors
214
- the two side airbags located in the sides of the
front backrests
- the airbag warning light in the instrument clus-
ter.
The airbag system is mon itored electron ical ly to
make certain that it is functioni ng p roperly at all
times. Each time you turn on the ignition, the air­
bag system indicator light will come on for a few
seconds (self diagnostics) .
The side airbag system supplements the safety
belts and can help to reduce the risk of injury to
the driver's and front passenger's upper torso
and head on the side of the vehicle that is struck
in a side collision. The airbag deploys in side im­
pacts and only when the vehicle acceleration reg­
istered by the control unit is high enough. If this
rate is below the reference value programmed in­
to the control unit, the side airbags will not be
trigge red, even though the car may be badly
damaged as a result of the collision .
It is not pos­
sible to define an airbag triggering range that
will cover every possible angle of impact, since
the circumstances will vary conside rably between
one collision and another. Important factors in­
clude, for example, the nature (hard or soft) of
the impacting object, the angle of impact, vehicle
speed, etc.
c::> page 216, Important safety in­
structions on the side airbag system .
Aside from their normal safety function, safety
belts work to help keep the driver or front pas­
senger in position in the event of a side collision
so that the side airbags can provide protect ion.
The airbag system is
not a substitute for your
safety belt. Rather, it is part of the overall occu­
pant restraint system in your vehicle . Always re­
member that the side airbag system can only
help to protect you if you are wear ing your safety
belt and wear ing it properly. This is another rea­
son why you sho uld always wear your safety
belts, not just because the law requires you to do
so
c::> page 189, General notes.
It is impo rtant to remember that while the sup­
plemental side airbag system is desig ned to re­
duce the likelihood of ser ious injuries, other inju­
ries, for example, swelling, bruising , friction
burns and minor abrasions can also be associated ..,.

with deployed side airbags. Remember too, side
airbags will deploy on ly once and on ly in certain
kinds of acc idents -your safety be lts are always
there to offer protection .
Vehicle damage, repair costs or even the lack of
vehicle damage are not necessarily an indication
of over-sensitive or failed airbag activation. In
some collisions, both front and side airbags may
inflate. Remember too, that airbags will deploy
only once and only in certain kinds of coll isions -
your safety belts are always there to offer protec­
tion in those acc idents in which airbags are not
supposed to deploy or when they have a lready
deployed.
The side airbag system will not deploy:
-when the ign ition is switched off
- in side collisions when the acceleration meas-
ured by the sensor is too low
- in front-end collisions
- in rear-end collisions
- in rollovers.
I n some types of accidents the front airbags and
side airbags may be triggered together.
_& WARNING
-Safety belts and the airbag system will only
provide protection when occupants are in
the proper seating position ¢
page 216.
-If the airbag indicator light q page 14
comes when the vehicle is being used, have
the system inspected immediate ly by your
authorized Audi dealer. It is possible that
the airbag will inflate when it is not sup­
posed to, or will not inflate when it shou ld.
Airbag system
How supplemental side airbags work
Side airbags deploy instantly and can help re­
duce the risk of upper torso injuries for occu­
pants who are properly restrained.
Fig. 170 Inflated side a irbags on lef t side of vehicle
When the system is triggered, the airbag is filled
with propellant gas and breaks through a seam in
the seat surface area marked "AIRBAG". It ex­
pands between the side trim panel and the pas­
senger . In order to help provide this addit ional
protect ion, the side airbag must inflate w ith in a
fraction of a second at very high speed and with
great force . Th e supp lemental s ide airbag could
injure you if you r seating position is not proper or
u pr ight or if items are located in the area where
the supp lemental side airbag expands. This ap­
plies especially to children
c> page 218, Child
safety.
Supplemental side airbags inflate be­
tween the occupant and the door panel on the
side of the vehicle that is struck in certain side collision
c> fig . 170.
Although they are not a soft pillow, they can
"cushion" the impact and in this way they can
help to reduce the risk of injury to the upper part
of the body .
A fine dust may develop when t he airbag deploys .
This is normal and does not mean there is a fire
in the veh icle.

Airbag system
Important safety instructions on the side
airbag system
Airbags are only supplemental restraints. Always
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 provide supplemental protection .
A WARNING
An inflating side airbag can cause serious or
fatal injury. Improperly wearing safety belts
and improper seating positions increase 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 supple-
mental 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 replacement
upholstery over the front seatbacks that have not been specifically approved by
Audi .
- Never use additional seat cushions that cover the areas where the side airbags de­
ploy .
- Damage to the original seat covers or to
the seam in the area of the side airbag
module must always be repaired immedi­
ately by an authorized Audi dealer.
- Objects between you and the airbag can in­
crease the risk of injury in an accident by in­
terfering with the way the airbag unfolds or
216
-
by being pushed into you as the airbag in­
flates .
- Never place or attach accessories or other
objects (such as cup holders , telephone
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 become
dangerous projectiles and cause injury
when the supplemental side airbag de­ ploys.
- Never carry any objects or pets in the de­
ployment space between them and the
airbags or allow children or other passen­
gers to travel in this position .
- Always prevent the side airbags from being
damaged by heavy objects knocking against
or hitting the sides of the seatbacks .
- The airbag system can only be triggered
once . If the airbag has been triggered, the
system must be replaced by an authorized
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 authorized
Audi dealer .
- If children are seated improperly, their risk
of injury increases in the case of an accident
~ page 218, Child safety .
-Never attempt to modify any components of
the airbag system in any way .
- In a side collision, side airbags will not func­
tion properly if sensors cannot correctly
measure increasing air pressure inside the
doors when air escapes through larger, un­
closed openings in the door panel.
- Never drive with interior door trim panels
removed.
- Never drive when parts have been re­ moved from the inside door panel and the
openings they leave have not been proper­
ly closed.
- Never drive when loudspeakers in the
doors have been removed unless the speaker holes have been properly closed .

Child safety
Child safety
Important information
Introduction
The physical principles of what happens when
your vehicle is in a crash apply also to children
¢ page 190, What happens to occupants not
wearing safety belts?.
But unlike adults and
teenagers, their muscles and bones are not fully
developed. In many respects children are at
greater risk of serious injury in crashes than
adults.
Because children's bodies are not fully devel­
oped, they require restraint systems especially
designed for their size, weight, and body struc­
ture. Many countries and all states of the United
States and provinces of Canada have laws requir­
ing the use of approved child restraint systems
for infants and small children .
In a frontal crash at a speed of 20-35 mph (30-56 km/h) the forces acting on a 13 lbs (6 kg)
infant will be more than 20 times the weight of
the child . This means the weight of the child
would suddenly be more than 260 lbs (120 kg).
Under these conditions, only an appropriate child
restraint properly used can reduce the risk of se­
rious injury. Child restraints, like adult safety
belts, must be used properly to be effective.
Used improperly, they can increase the risk of se­
rious injury in an accident.
If you must install a child restraint on the front
passenger seat in exceptional circumstances, be
sure to read and heed the important information
and warnings ¢
page 197. Infants and other chil­
dren who are properly restrained in an appropri­
ate child restraint that is for their size and age
can benefit from the protection that supplemen­
tal side airbags provide in some kinds of crashes .

Consult the child safety seat manufacturer's in­
structions in order to be sure the seat is right for
your child's size

instructions for using child safety seats.
Please
be sure to read and heed all of the important in­
formation and WARNINGS about child safety,
Advanced Airbags, and the installation of child
restraints in this chapter .
There is a lot you need to know about the Ad­
vanced Airbags in your vehicle and how they work
when infants and children in child restraints are
on the front passenger seat. Because of the large
amount of important information, we cannot re­
peat it all here . We urge you to read the detailed
information in this owner's manual about airbags
and the Advanced Airbag System in your vehicle
and the very important information about trans­ porting children on the front passenger seat.
Please be sure to heed the WARNINGS -they are
extremely important for your safety and the safe­
ty of your passengers, especially infants and
small children .
A WARNING
All vehicle occupants and especially children
must be restrained properly whenever riding
in a vehicle . An unrestrained or improperly re­
strained child could be injured by striking the
interior or by being ejected from the vehicle
during a sudden maneuver or impact. An un­
restrained or improperly restrained child is al­
so at greater risk of injury or death through
contact with an inflating airbag.
A WARNING
Children on the front seat of any car even with
Advanced Airbags can be seriously injured or
even killed when an airbag inflates . A child in
a rearward-facing child safety seat installed
on the front passenger seat will be seriously
injured and can be killed if the front airbag in­
flates.
- 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 armrest, or
door.
