2019 AUDI TT ROADSTER seats

Safety belts

offer protection in those accidents in which air-
bags are not supposed to deploy or when they
have already deployed. Unbelted occupants can
also be thrown out of the vehicle where even
more severe or fatal injuries can occur.
Safety belts protect
People think it's possible to use the hands to
brace the body ina minor collision. It's simply
not true!

Safety belts used properly can make a big differ-
ence. Safety belts help to keep passengers in
their seats, gradually reduce energy levels ap-
plied to the body in an accident, and help prevent
the uncontrolled movement that can cause seri-
ous injuries. In addition, safety belts reduce the
danger of being thrown out of the vehicle.
Safety belts attach passengers to the car and give
them the benefit of being slowed down more
gently or “softly” through the “give” in the safety
belts, crush zones and other safety features engi-
neered into today's vehicles. By “absorbing” the
kinetic energy over a Longer period of time, the
safety belts make the forces on the body more
“tolerable” and less likely to cause injury.
Although these examples are based on a frontal
collision, safety belts can also substantially re-
duce the risk of injury in other kinds of crashes.
So, whether you're on a long trip or just going to
the corner store, always buckle up and make sure
others do, too. Accident statistics show that vehi-
cle occupants properly wearing safety belts have
a lower risk of being injured and a much better
chance of surviving an accident. Properly using
184

safety belts also greatly increases the ability of
the supplemental airbags to do their job in a col-
lision. For this reason, wearing a safety belt is le-
gally required in most countries including much
of the United States and Canada.
Although your Audi is equipped with airbags, you
still have to wear the safety belts provided. Front
airbags, for example, are activated only in some
frontal collisions. The front airbags are not acti-
vated in all frontal collisions, in side and rear col-
lisions, in rollovers or in cases where there is not
enough deceleration through impact to the front
of the vehicle. The same goes for the other airbag
systems in your Audi. So, always wear your safety
belt and make sure everybody in your vehicle is
properly restrained!

Safety belts must always be correctly positioned
across the strongest bones of your body.
> Always wear safety belts as illustrated and de-
scribed in this chapter.
> Make sure that your safety belts are always
ready for use and are not damaged.

ZA WARNING
Not wearing safety belts or wearing them im-
properly increases the risk of serious personal
injury and death. Safety belts can work only
when used correctly.
— Always fasten your safety belts correctly be-
fore driving off and make sure all passen-
gers are correctly restrained.
— For maximum protection, safety belts must
always be positioned properly on the body.
— Never strap more than one person, including
small children, into any belt.
— Never place a safety belt over a child sitting
on your lap.
— Always keep feet in the footwell in front of
the seat while the vehicle is being driven.
— Never let any person ride with their feet on
the instrument panel or sticking out the
window or on the seat.

Safety belts



— Never remove a safety belt while the vehicle
is moving. Doing so will increase your risk of
being injured or killed.
— Never wear belts twisted.
— Never wear belts over rigid or breakable ob-
jects in or on your clothing, such as eye
glasses, pens, keys, etc., as these may cause
injury.
— Never allow safety belts to become dam-
aged by being caught in door or seat hard-
ware.
— Do not wear the shoulder part of the belt
under your arm or otherwise out of position.
— Several layers of heavy clothing may inter-
fere with correct positioning of belts and re-
duce the overall effectiveness of the system.
— Always keep belt buckles free of anything
that may prevent the buckle from latching
securely.
— Never use comfort clips or devices that cre-
ate slack in the shoulder belt. However, spe-
cial clips may be required for the proper use
of some child restraint systems.
— Torn or frayed safety belts can tear and
damaged belt hardware can break in an acci-
dent. Inspect belts regularly. If webbing,
bindings, buckles, or retractors are dam-
aged, have belts replaced by an authorized
Audi dealer or qualified workshop.
— Safety belts that have been worn and loaded
in an accident must be replaced with the
correct replacement safety belt by an au-
thorized Audi dealer. Replacement may be
necessary even if damage cannot be clearly
seen. Anchorages that were loaded must al-
so be inspected.
— Never remove, modify, disassemble, or try
to repair the safety belts yourself.
— Always keep the belts clean. Dirty belts may
not work properly and can impair the func-
tion of the inertia reel > table Interior
cleaning on page 264.

Automatic safety belt retractors
Every safety belt is equipped with an automatic
belt retractor on the shoulder belt. This feature
locks the belt when the belt is pulled out fast,
during hard braking and in an accident. The belt
may also lock when you drive up or down a steep
hill or through a sharp curve. During normal driv-
ing the belt lets you move freely.
Safety belt pretensioners
Safety belts with pretensioners help to tighten
the safety belt and remove slack when the pre-
tensioners are activated > page 187. The func-
tion of the pretensioner is monitored by a warn-
ing light > page 18.

Safety belt position.
— Safety belts offer optimum protection only
when the seatback is upright and belts are
properly positioned on the body.
— Never attach the safety belt to the buckle
for another seat. Attaching the belt to the
wrong buckle will reduce safety belt effec-
tiveness and can cause serious personal in-
jury.
— A passenger who is not properly restrained
can be seriously injured by the safety belt it-
self when it moves from the stronger parts
of the body into critical areas like the abdo-
men.
— Always lock the convertible locking retractor
when you are securing a child seat in the ve-
hicle > page 220.

— The shoulder belt should lie as close to the
center of the collar bone as possible and
should fit well on the body. Hold the belt
above the latch tongue and pull it evenly
across the chest so that it sits as low as pos-
sible on the pelvis and there is no pressure
on the abdomen. The belt should always fit
snugly > fig. 152. Pull on the belt to tighten
if necessary.
—A loose-fitting safety belt can cause serious
injuries by shifting its position on your body
from the strong bones to more vulnerable,
soft tissue and cause serious injury.
— Always read and heed all WARNINGS and
other important information > page 184.
Pregnant women must also be correctly
restrained

The best way to protect the fetus is to make sure
that expectant mothers always wear safety belts
correctly - throughout the pregnancy.

Airbag system

also not inflate in side or rear collisions, or in roll-
overs.
Always remember: Airbags will deploy only once,
and only in certain kinds of collisions. Your safety
belts are always there to offer protection in those
situations 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 vehicle after the first collision.
This is just one of the reasons why an airbag is a
supplementary restraint and is not a substitute
for a safety belt. The airbag system works most
effectively when used with the safety belts.
Therefore, always properly wear your safety belts
=> page 182.

— Always sit upright with your back against
the backrest of your seat.
— Never place your feet on the instrument
panel or on the seat. Always keep both feet
on the floor in front of the seat to help pre-
vent serious injuries to the legs and hips if
the airbag inflates.


ZA WARNING
Sitting too close to the steering wheel or in-
strument panel will decrease the effective-
ness of the airbags and will increase the risk
of personal injury in a collision.
— Never sit closer than 10 in (25 cm) to the
steering wheel or instrument panel.
— If you cannot sit more than 10 in (25 cm)
from the steering wheel, investigate wheth-
er adaptive equipment may be available to
held you reach the pedals and increase your
seating distance from the steering wheel.
— If you are unrestrained, leaning forward, sit-
ting 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.
— To reduce the risk of injury when an airbag
inflates, always wear safety belts properly
=> page 185, Safety belts.
— If children are not properly restrained, they
may be severely injured or killed when an
airbag inflates.
— Never let children ride unrestrained or im-
properly restrained in the vehicle. Adjust the
front seats properly.
— Always sit as far as possible from the steer-
ing wheel or the instrument panel
=>page 178.
ZA WARNING
Airbags that have deployed in a crash must be
replaced.
— Use only original equipment airbags ap-
proved by Audi and installed by a trained
technician who has the necessary tools and
diagnostic equipment to properly replace
any airbag in your vehicle and assure system
effectiveness ina crash.
— Never permit salvaged or recycled airbags to
be installed in your vehicle.

Child restraints on the front seat - some
important things to know

> Be sure to read the important information and
head the WARNINGS for important details
about children and Advanced Airbags
=> page 210.
The airbag on the passenger 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 forward-facing child safety seat. It can
be a very dangerous place for an infant or a child
in a rearward-facing seat.
The Advanced Airbag System in your vehicle has
been certified to comply with the requirements
of United States Federal Motor Vehicle Safety
Standard (FMVSS) 208, as well as Canada Motor
Vehicle Safety Standard (CMVSS) 208 as applica-
ble at the time your vehicle was manufactured.
According to requirements, the front Advanced
Airbag System on the passenger side has been
certified for “suppression” for infants of about
12 month old and younger and for “low risk de-
ployment” for children aged 3 to 6 years old (as
defined in the standard).

8S8012721BA
Airbag system

The PASSENGER AIR BAG OFF %; light in the
headliner tells you when the front Advanced Air-
bag on the passenger side has been turned off by
the electronic control unit.
Each time you turn on the ignition, the PASSEN-
GER AIR BAG OFF #¥; ON ® light will come on
for a few seconds and:
— PASSENGER AIR BAG OFF #¥; will come on if
the front passenger seat is not occupied,
— PASSENGER AIR BAG OFF 3; will come on if
the electrical capacitance measured by the ca-
pacitive passenger detection system for the
front passenger seat equals the combined ca-
pacitance of an infant up to about one year of
age and one of the rearward-facing or forward-
facing child restraints listed in Federal Motor
Vehicle Safety Standard 208 with which the Ad-
vanced Airbag System in your vehicle was certi-
fied. For a listing of the child restraints that
were used to certify your vehicle's compliance
with the U.S. Safety Standard = page 212.
— PASSENGER AIR BAG OFF 3; will come on if
there is a small child or child restraint on the
front passenger seat,
— PASSENGER AIR BAG ON @ will go off if the
front passenger seat is occupied by an adult as
registered by the capacitive passenger detec-
tion system > page 200, Monitoring the Ad-
vanced Airbag System.
The PASSENGER AIR BAG OFF 3%; light comes on
when electrical capacitance registered on the
front passenger seat is equal to or less than the
combined capacitance of a typical 1 year-old in-
fant and one of the rearward-facing or forward-
facing child restraints listed in Federal Motor Ve-
hicle Safety Standard 208 with which the Ad-
vanced Airbag System in your vehicle was certi-
fied.
If the total electrical capacitance registered on
the front passenger seat is more than that of a
typical 1 year-old child but less than the weight
of a small adult, the front airbag on the passen-
ger side can deploy (the PASSENGER AIR BAG
OFF 3%; light does not come on).
If the PASSENGER AIR BAG OFF %; light does
not come on, the front airbag on the passenger
side has not been turned off by the electronic
control unit and can deploy if the control unit
senses an impact that meets the conditions stor-
ed in its memory.
For example, the airbag may deploy if:
—asmall child that is heavier than a typical 1
year-old child is on the front passenger seat (re-
gardless of whether the child is in one of the
child safety seats listed > page 212), or
—a child who has outgrown child restraints is on
the front passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF #; light comes on in
the headliner and stays on.
If the front passenger airbag deploys, the Federal
Standard requires the airbag to meet the “low
risk” deployment criteria to reduce the risk of in-
jury through interaction with the airbag. “Low
risk” deployment occurs in those crashes that
take place at lower decelerations as defined in
the electronic control unit > page 200, PASSEN-
GER AIR BAG OFF $; ON ® light.
Always remember, a child seat or infant carrier
installed on the front seat may be struck and
knocked out of position by the rapidly inflating
passenger's airbag in a frontal collision. The air-
bag could greatly reduce the effectiveness of the
child restraint and even seriously injure the child
during inflation.

A WARNING
A child in a rearward-facing child seat instal-
led on the front passenger seat will be seri-
ously injured and can be killed if the front air-
bag inflates - even with an Advanced Airbag
System.
— The inflating airbag will hit the child seat or
infant carrier with great force and will
smash the child seat and child against the
backrest, center armrest, door or roof.
— Forward-facing child seats installed on the
front passenger's seat may interfere with
the deployment of the airbag and cause seri-
ous personal injury to the child.

The PASSENGER AIR BAG OFF %; light comes on
when the electronic control unit detects a total
electrical capacitance on the front passenger seat
that requires the front airbag to be turned off. If
the PASSENGER AIR BAG OFF 3%; light does not
come on, the front airbag on the passenger side
has not been turned off by the control unit and
can deploy if the control unit senses an impact
that meets the conditions stored in its memory.
If the total electrical capacitance registered on
the front passenger seat is more than that of a
typical 1 year-old, but less than the weight of a
small adult, the front airbag on the passenger

A WARNING
A child in a rearward-facing child seat instal-
led on the front passenger seat will be seri-
ously injured and can be killed if the front air-
bag inflates - even with an Advanced Airbag
System.
— Although the Advanced Airbag System in
your vehicle is designed to turn off the front
airbag when a rearward-facing child re-
straint has been installed on the front pas-
senger seat, nobody can absolutely guaran-
tee that deployment is impossible in all con-
ceivable situations that may happen during
the useful life of your vehicle.
— The inflating airbag will hit the child seat or
infant carrier with great force and will
smash the child seat and child against the
backrest, center armrest, door, or roof.
— Ifyou must install a rearward facing child
safety seat on the front passenger seat be-
cause of exceptional circumstances and the
PASSENGER AIR BAG OFF %; light does not
come on and stay on have the airbag system
inspected by your Audi dealer.


ZA WARNING
To reduce the risk of injury when an airbag in-
flates, always wear safety belts properly.
— If you are unrestrained, leaning forward, sit-
ting sideways or out of position in any way,
your risk of injury is much higher.
— You will also receive serious injuries and

ZA WARNING
If, in exceptional circumstances, you must in-
stall 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 manu-
facturer for use on a front seat with a pas-
senger front and side airbag.
— Never put the forward-facing child restraint
up against or very near the instrument pan-
el.
— Always move the front passenger seat to the
highest position in the up and down adjust-
ment range and move it back to the rear-
most position in the seat's fore and aft ad-
justment range, as far away from the airbag
as possible, before installing the forward-
facing child restraint.

— 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
put them on the seat. The capacitive passen-
ger detection mat in the front passenger
seat will not function properly if it is punc-
tured.
— Never carry things on your lap or carry ob-
jects on the front passenger seat. Such ob-
jects can
influence the capacitance regis-
tered by the capacitive passenger detection
system, so that incorrect information is pro-
vided 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 dam-
aged, preventing them and the airbag sys-
tem from working properly.
— Never place seat covers or replacement up-
holstery that have not been specifically ap-
proved by Audi on the front seats.
— 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.
— If a seat heater has been retrofitted or oth-
erwise added to the front passenger seat,
never install any child restraint system on
this seat.
— Never use cushions, pillows, blankets, or
similar items on the front passenger seat.
The additional layers prevent the capacitive
passenger detection system from accurately
measuring the capacitance of the child safe-
ty seat and/or the person on the seat and
thus keep the Advanced Airbag System from
working properly.
— Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat heater
for child seats) on the front passenger seat
if the device is connected to the 12-volt
socket or the cigarette lighter socket. Such
devices can influence the capacitance regis-
tered by the capacitive passenger detection

system, so that incorrect information is pro-
vided to the airbag control unit.
— If you must use a child restraint on the front
passenger seat and the child restraint man-
ufacturer'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, have the air-
bag system inspected by your Audi dealer.

ZA WARNING
If the front passenger seat gets wet, dry it im-
mediately.
— If liquid soaks into the front passenger seat,
this can keep the airbag system from work-
ing properly and may, for instance, deacti-
vate the passenger frontal airbag. If this
happens, the PASSENGER AIR BAG OFF ¥,
light will come on and stay on together with
the airbag indicator light ka in the instru-
ment cluster.
— If liquid is pooled on the seat, but has not
soaked in, this may also keep the airbag sys-
tem from working properly and cause the
passenger frontal airbag to be enabled
(turned on), even though there is a properly
installed child restraint system on the seat.
Wet towels or other wet things on the seat
cushion can have the same effect. If the
front passenger frontal airbag is turned on,
the PASSENGER AIR BAG OFF #; light will
turn off.

Airbag system

Deployment of the Advanced Airbag System and
the activation of the safety belt pretensioners de-
pend on the deceleration measured by the crash
sensors and registered by the electronic control
unit. Crash severity depends on speed and decel-
eration as well as the mass and stiffness of the
vehicle or object involved in the crash.
On the passenger side, regardless of safety belt
use,
the front passenger frontal airbag will be
turned off if the electrical capacitance measured
by the capacitive passenger detection system on
the front passenger seat is less than the amount
programmed in the electronic control unit. The
front passenger frontal airbag will also be turned
off if the capacitance measured by the system for
the front passenger seat equals that of an infant
of about one year of age in one of the child seats
that was used to certify the Advanced Airbag Sys-
tem under Federal Motor Vehicle Safety Standard
208. The PASSENGER AIR BAG OFF #; light
comes on and stays on to tell you when the front
Advanced Airbag System on the passenger side
has been turned off > page 200.

Z\ WARNING
To reduce the risk of injury when an airbag in-
flates, always wear safety belts properly.
— If you are unrestrained, leaning forward, sit-
ting 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

Fig. 157 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 supple-
mental protection in a frontal collision.
The front airbags are designed to provide addi-
tional protection for the chest and face of the
driver and the front seat passenger when:
— safety belts are worn properly,
— the seats have been positioned so that the oc-
cupant is properly seated as far as possible
from the airbag.
Because airbags inflate in the blink of an eye with
great force, things you have on your lap or have
placed on the seat could become dangerous pro-
jectiles, and be pushed into you if the airbag in-
flates.
When an airbag deploys, fine dust is released.
This is normal and is not caused by a fire in the
vehicle. This dust is made up mostly of a powder
used to lubricate the airbags as they deploy. It
could irritate skin.
It is important to remember that while the sup-
plemental airbag system is designed to reduce
the likelihood of serious injuries, other injuries,
for example swelling, bruising and minor abra-
sions, can also happen when airbags inflate. Air-
bags do not protect the arms or the lower parts
of the body. Front airbags supplement the three
point safety belts only in some frontal collisions
in which the vehicle deceleration is high enough
to deploy the airbags.
Front airbags will not deploy:
— if the ignition is switched off when a crash oc-
curs,
— in side collisions,
—in rear-end collisions,
—in rollovers,
— when the crash deceleration measured by the
airbag system is less than the minimum thresh-
old needed for airbag deployment as registered
by the electronic control unit.
The front passenger airbag will also not
deploy:
—when the front passenger seat is not occupied, >
