2018 AUDI A3 SEDAN turn signal

Airbag syste m
A WARNING
A child in a rearward-facing child seat instal­
led o n the front passenger seat will be ser i­
ously injured and can be k ille d if the front air­
bag in flate s - even with an Advanced Airbag
System.
- The inflating a irbag w ill hit the child seat or
infant carrier w ith great force and will
smash the ch ild seat and child against the
backrest, cente r arm rest, door or roof.
- Always install rear-facing child seats on the
rea r seat.
- If you must install a rearward fac ing ch ild
seat on the front passenger seat because of
exceptional c ircumstances and the
PASSEN­
GER AIR BAG OFF
light does not come on
and stay on, immediately insta ll the rear­
facing child seat in a rear seating position and have the airbag system inspected by
your Audi dealer.
A WARNING
-
-
Objects between you and the a irbag w ill in­
crease the risk of in jury in a crash by interfer­
ing w ith the way the airbag unfolds or by be­
ing pushed into you as the a irbag inflates.
- Never hold th ings in your hands or on your
lap when the vehicle is in use .
- Never transport items on or in the area of
the fron t passenger seat . Objects could
move into the area of the front airbags du r­
ing bra king or other sudden maneuve rs and
become dangerous projec tiles that c an
ca use serious pe rsonal injury if the a irbags
inflate.
- Never pl ace or attach accessor ies or o ther
objects (such as cup ho lders, te lephone
brackets, large, heavy or bulky objects) on
the doors, over or nea r the area marked
"AIRBAG" on the steering wheel, instru­
ment pane l, seat backrests or between
those areas and yourself. These objects could cause injury in a crash, especially
when the airbags infla te.
- Never recline the front passenger's seat to
transport objects . Items can also move into
the a rea of the side airbag o r the front a ir-
280
bag du ring brak ing o r in a sudden maneu­
ver. Objects near the airbags can become pro jecti les and cause injury, part icularly
when the seat is reclined .
- Never p lace or transport objects on the
front passenger seat. Objects on the front passenger seat could cause the capacitive
sensor in the seat to signal to ai rbag system
that the seat is occ upied by a person when it
in fact is no t, or that the pe rson on the seat
is he avie r th an he or she act ually is. The
change in electric capacitan ce beca use of
such objects can cause the passenge r front
airbag to be turne d on when it should be
off, or can cause the airbag to work in a way
that is different from the way it would have
wo rked without objects on the seat.
- Always make sure that there is noth ing on
the front passenger seat that will cause the
capacitive passenger detection system in
the sea t to signal to the Airbag System that
the seat is occup ied by a person when it is
not, or to signal that it is occupied by some­
one who is heavier th an the person actu ally
si tting on the sea t. The presence of an o b­
ject could ca use the passenger front air bag
to be turned on when it should be off, or
could cause the airbag to work in a way that is diffe rent from the way it would have
worked without the object on the seat.
A WARNING
The fine dust created when airbags deploy can
cause breathing prob lems for people with a
h istory of asthma or othe r breath ing cond i­
tions .
- To reduce the r isk of breathing p roblems ,
those wi th asthma o r other respiratory con­
ditions sho uld get fresh a ir rig ht away by
getting out of the vehi cle or opening win­
dows or doors.
- If you are in a co llision in which airbags de­
ploy, w ash yo ur hands and f ace with m ild
soap and water be fore eating.
- Be ca refu l not to get the dust into your eyes,
or into any cuts or scratches.
- If the residue sho uld get into your eyes,
flush them w ith wate r.

Monitoring the
Advanced Airbag System
Airbag monitoring indicator light
Two separate indicators monitor the fun ction of
the Advanced Airbag System : the
El ligh t and
t he
PASSENGER AIR BAG OFF light.
The Advanced Airbag System as we ll as the side
a ir bags and side curta in airbags with ejec tion
m it iga tion feat ures ( incl udi ng t he e lectro nic con­
tro l unit, sensors and system wiring) are all
monitored co nti nu ously to ma ke sure that they
are funct ion ing prope rly whenever the ignition is
on. Every t ime yo u turn on the ignition, the air ­
bag system ind icator
light E,lwill come on for a
few seconds (function check).
The system mu st be inspected when the
indicator light
E,I:
- does not come on when the ignit ion is switched
on,
- does not go out a few seconds after you have
switched on the ign ition, o r
- comes on w hile driving.
If an airbag sys tem malf unct ion is de tected, the
indicator light w ill come on to serve as a co nstant
rem inder to have the system inspected immedi­
ately .
If a mal function occurs t hat turns the front air ­
bag on the passenger si de
off, the PASSENGER
AIR BAG OFF
light will come on and stay on
whenever the ignit io n is on.
A WARNING
An airbag system that is not funct ion ing prop­
er ly cannot provide supplemental p rotection
in a frontal crash .
- If the airbag indicator light¢
page 26
comes when the vehicle is be ing used, have
the sys te m inspect ed immed iate ly by yo ur
au tho riz ed Au di dealer.
It is possible that
t h e air bag will in flate w hen it i s n ot su p­

spe cted imme dia tely by your au thori zed A udi
dealer.
The PASSENGER AIR BAG OFF light will blink
for about 5 seconds when:
- the ignition is sw itched on and
- the capacit ive passenger detection system,
which switches the front seat passenger 's fron­
t al Advanced Airbag on and
off, detects a
change i n the status of the front passenger
seat.
As soon as the
PASSENGER AIR BAG OFF light
stops blinking, always ma ke sure that the a irbag
status (on or off) as shown by the

Child restraints and Advanced front airbag
system
Regardless of the child restraint that you use,
make sure that it has been certified to meet Safe­
ty Standards and has been certified by its manu­
facturer for use with an airbag. Always be sure
that the child restraint is properly installed at
one of the rear seating positions . If in exception­
al c ircumstances you must use it on the front
passenger seat, carefully read all of the informa­
tion on child safety and Advanced Airbags and
heed all of the applicable WARNINGS. Make cer­
tain that the child and child restraint are correct­
l y recognized by the capacitive passenger detec­
tion system in 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 mode ls are in­
troduced regularly incorporat ing new and im­
proved designs and older models are taken out of
product ion . Child restraints are not standardized .
Ch ild restraints of the same type typically have
different weights and size s and different "foot­
prints", the size and sh ape of the bottom of the
chi ld restraint that sits on the seat, when they
are installed on a vehicle seat. These differences
make it virtua lly 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 veh icle.
F or this reason, the United States National High­
way Traffic Safety Administration has published a
list of specific type, makes and models of child
restraints that must be used to certify compli­
ance of the Advanced Airbag System in your vehi­
cle with the suppression requirements of Federal
Motor Vehicle Safety Standard 208. These child
restraints are:

Wheels
~ Adapt your driving style to the situation.
~ Stop as soon as possible and check the tire(s) .
~ If it is possible to continue driving, see an au-
thorized Audi dea ler or authorized Audi Service
Facility immediately and have your tire(s) re­
paired or replaced.
A WARNING
Read and follow the important information
and
notes ~ page 350.
Storing new tire pressures
App lies to: ve hicles w ith tire press ure m on itoring system
Correctly stored tire pressure specifications are
necessary for reliable tire pressure monitoring.
-
It is always necessary to store the tire pressures
when the tire pressures are modified, for exam­ ple due to a change in load. or when new sensors
are installed .
~ Before storing the tire pressures, make sure the
tire pressures of all four tires meet the speci­
fied values and are adapted to the load
~ page 341, fig . 2 78 . Only correct and store
the pressure in tires whose temperature is ap­
prox imat ely the same as the ambient tempera­
ture .
If the temperature of the tire is higher
than the ambient air temperature, the tire
pressure must be increased approximate ly
3 .0 PSI (0 .2 bar) above the va lue on the sticker .
~ Switch the ignition on.
~ Select in the Infotainment system: IMENUI but­
ton
> Vehicle > left control button > Service &
checks > Tire pressure monitoring > Store tire
pressure > Yes, store now .
After storing the
tire pressu res, the t ire pressu re monitoring sys­
tem measures the current pressures wh ile driv­
in g and stores them as the new specified pres­
sures.
~ If the changed tire pressures are not displayed
in the Infotainment system, drive the vehicle
for approximate ly 10 minutes so that the sen­
sor signal from the wheels is received again.
During this adaptation phase, --.-- is displayed
for the pressure and temperature and the tire
pressure mon itor ing system is only partially
ava ilable. It only provides a warning if one or
352 more
tire pressures is below the minimum per­
mitted specified pressure.
If the
[I] ind icator light turns on and the mes­
sage
Tire pressure : wheel change detected .
Please check all tires and store pressures in
MMI also appears, the system has detected that
the position of the sensors has changed because
of a tire rotation, or that new sensors were in­
stalled. Store the new tire pressures.
A WARNING
Read and follow the important information
and notes
~pag e 350.
Malfunctions
Applies to: vehicles with t ire pressure mo nitori ng syste m
If the tire pressure monitoring system is not
available, t he
mm in dicator light appears in the
instr umen t cluste r display along with the mes­
sage
Tire pressure : malfun ction! See owner's
manual.
-
If the ffim ind icator light appears after switch­
in g the ignitio n on or wh ile dr iving and the
[IJ in­
dicator light also blinks for approximately one
minute and then stays on, there is a system ma l­
function . The fo llowing are examples of situa­
tions that could cause a malfunction:
- If the message appears at the end of the adap ­
tation phase, the system may not detect one or
several of the whee l sensors necessary for pres­
sure monitoring. This may res ult from one or
more whee ls being installed without wheel sen­
sors or with incompatible wheel sensors.
- A wheel sensor or another component has
fa iled.
- Using snow chains can affect the function of
the system because of the shielding effect of
the chains.
- The tire pressure monitoring system is not
avai lab le due to a ma lfunction.
- Transmitters with the same frequency, such as
headphones or remote-controlled devices, may
cause a temporary system malfunct ion due to
the strong electromagnetic field.
