2018 AUDI TT ROADSTER seat memory

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.
E ach time you turn on the ignition, the
PASSEN­
GER AIR BAG OFF
"1; 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 ~; will come on if
t h e e lectrica l capacitance measured by the ca­
pacitive passenger detection system for the
front passenger seat equa ls 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 w ith which the Ad­
vanced Airbag System in your vehicle was certi­
fied. For a listing of the ch ild restraints that
were used to cert ify your vehicle 's compliance
with the U.S. Safety Standard
¢page 218.
- PASSENGER AIR BAG OFF~; will come on if
there is a small child or ch ild rest raint on the
front passenger seat,
-PASSENGER AIR BAG ON @w ill go off if the
front passenger seat is occupied by an adult as
registered by the capacitive passenger detec­
tion system ¢
page 205, Monitoring the Ad­
vanced Airbag System .
The PASSENGER AIR BAG OFF~; light comes on
when electrical capacitance registered on t he
front passenger seat is equa l to or less than the
combined capacitance of a typica l 1 year -o ld in­
fant and one of the rearward-facing or forward ­
facing ch ild restraints listed in Federal Motor Ve­
h icle Safety Standard 208 with wh ich the Ad­
vanced A irbag System in your vehicle was cert i­
f ie d.
If the tota l electrical capac itance registered on
the front passenger seat is more than that of a
typical 1 year-old child but less than the we ight
of a small adult, the front a irbag on the passen­
ge r side ca n deploy (the
PASSENGER AIR BAG
OFF
"1; light does not come on).
If the
PASSENGER AIR BAG OFF "1; light does
not come on, the front a irbag on the passenger
196
side has not been turned off by the electronic
contro l unit and can deploy if the contro l unit
senses an impact that meets the conditions stor­
ed in its memory.
For example , the airbag may deploy
if:
-a small c hild that is heav ier than a typica l 1
year-old child is on the front passenger seat
(regard less of whethe r the child is in one of the
child sa fety seats listed ¢
page 218), or
- a child who has outgrown child restraints is on
the front passenger seat.
If the front passenger a irbag is turned off, the
PASSENGER AIR BAG OFF~; light comes on in
the headliner and stays on.
If the front passenger airbag deploys, the Feder­
al Standard requires the airbag to meet the "low
r isk" dep loyment cr iteria to reduce the r isk of in­
jury through interaction w ith the airbag. "Low
risk" deployment occurs in those crashes that
take place at lower decelerations as defined in
the e lectronic contro l unit ¢
page 206, PASSEN­
GER AIR BAG
OFF~; ON~ light.
A lways 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 col lision. The air­
bag could great ly reduce the effectiveness of the
c hi ld restraint and even ser iously injure the child
during inflat io n.
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 inflat ing 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 se­
r ious personal injury to the ch ild.

Airbag syste m
airbag on the passenger side may or may not
deploy.
The
PAS SENGER AIR B AG OFF ~; light comes o n
when the e lectron ic control un it detects a total
e lectrica l capacitance on the front passenger seat
that requires the front airbag to be turned
off . If
the
PASSENGER AIR BAG OFF '1; 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 tota l electrical capac itance 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
side may deploy (the
PASSENGER AIR BAG OFF
~ ; light does not come on).
For exampl e, th e airbag may d eploy if:
- a small child that is heavier than a typical 1
year-old ch ild is on the front passenger seat
(regardless of whether the child is in one of the
ch ild seats listed
r=;,page 218),
- a chi ld who has outgrown child restraints is on
the front passenger seat .
If the front passenger airbag is turned off , the
P ASS ENGER AIR BA G OFF~; light in the head­
liner will come on and stay on .
I f the front passenger airbag dep loys, the Feder ­
a l Standard requires the airbag to meet the "low
risk" deployment criteria to help reduce the risk
of injury through interaction with the airbag.
"Low risk" deployment occurs in those crashes
that take place at lower decelerations as def ined
i n the electronic control
un it ¢ page 205 .
Alw ays remember: Please be sure to read the im­
portant information in the sections that follow
and be sure to heed all of the WARNINGS .
A WARNING
To red uce the risk of inju ry when an a irbag in­
flates, a lways wear safety belts p roperly.
- If you are unrestrained, lean ing forward, s it­
t ing s ideways or out of pos ition in any way,
yo ur r isk of i njur y is m uch higher.

-You will a lso receive serious injuries and
could even be killed if yo u are up against the
airbag or too close to it when it inflates -
eve n with a n Advanced
Airbag ¢ page 194.
A WARNING
A child in a rearward-facing child seat instal­
led on t he front passenger seat will be seri­
ously injured and ca n be killed if the front air­
bag inflates -even with an Advanced Airbag
Sys tem.
- Altho ugh the Advanced Airbag System in
your veh icle is des igned to tur n
off the front
air bag w hen a rearward -fac ing c hild re ­
s traint has been installed on the front pas­
senger seat, nobody can abso lute ly guaran ­
tee t hat dep loyment is impossib le in all con ­
ceivab le situat ions that may happen d uring
the useful life of your vehicle.
- The inflating airbag will h it the ch ild seat or
infant carrier with great force and will
smash the child seat and child against the backrest, center armrest, door, or roof .
- If you m ust install a rearward facing child
safety seat on the front passenger seat be­
cause of except ional circ umstances and the
PASSENGER AIR BAG OFF ~; light does not
come on and stay on have t he a irbag system
inspected by yo ur Audi dea ler.
A WARNING
I f, in exceptional c ircumstances , you must in ­
s tall a forward -fa cing ch ild res trai nt on the
front passenger's seat:
- Always make sure the forward -fa cing sea t
has bee n des igned and certified by its man ­
ufacturer for use on a front seat with a pas ­
senge r front and side airbag.
- Never put the fo rward -facing chi ld restrain t
up against o r very near the instr ument pan ­
el.
- Always move the front passenger seat to
the highest position in the up and down ad ­
justment range and move it bac k to the
rearmost posit io n in the seat's fo re and aft
