2018 AUDI A5 COUPE change wheel

Airbag system
airbag inflates -even with an Advanced Airbag
System.
- 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, door or roof .
- Always install rear-facing child safety seats
on the rear seat .
- If you 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, immediately install
the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your authorized Audi dealer.
A WARNING
Objects between you and the airbag will in­
crease the risk of injury in a crash by interfer­
ing with the way the airbag unfolds or by be­
ing pushed into you as the airbag inflates.
- Never hold things in your hands or on your
lap when the vehicle is in use.
- Never transport items on or in the area of
the front passenger seat. Objects could move into the area of the front airbags dur­
ing braking or other sudden maneuvers and
become dangerous projectiles that can
cause serious personal injury if the airbags
inflate .
- Never place or attach accessories or other
objects (such as cupholders, telephone
brackets, large, heavy or bulky objects) on
the doors, over or near the area marked "AIRBAG'' on the steering wheel, instru­
ment panel, seat backrests or between
those areas and yourself. These objects could cause injury in a crash, especially
when the airbags inflate.
- Never recline the front passenger's seat to
transport objects. Items can also move into
the area of the side airbag or the front air­ bag during braking or in a sudden maneu­
ver. Objects near the airbags can become
288
-
projectiles and cause injury, particularly
when the seat is reclined .
- Never place 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 airbag system
that the seat is occupied by a person when it
in fact is not, or that the person on the seat
is heavier than he or she actually is. The
change in electric capacitance because of
such objects can cause the passenger front
airbag to be turned 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
worked without objects on the seat.
- Always make sure that there is nothing on
the front passenger seat that will cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that
the seat is occupied by a person when it is not , or to signal that it is occupied by some­
one who is heavier than the person actually
sitting on the seat. The presence of an ob­
ject could cause the passenger front airbag
to be turned on when it should be off, or
could cause the airbag to work in a way that
is different 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 problems for people with a history of asthma or other breathing condi­
tions .
- To reduce the risk of breathing problems,
those with asthma or other respiratory con­ ditions should get fresh air right away by
getting out of the vehicle or opening win­
dows or doors.
- If you are in a collision in which airbags de­
ploy, wash your hands and face with mild
soap and water before eating.
- Be careful not to get the dust into your eyes,
or into any cuts or scratches.
- If the residue should get into your eyes,
flush them with water .

Airbag syste m
Make sure that the PASSENGER AIR BAG
OFF
11;; li ght comes on and stays on all t he
t ime whenever the ignition is switched on.
A WARNING
- If the PA SSEN GER AIR BAG OFF 11;; light
does not go out when an adult is si tting on
the front passe nger seat a fter ta king the
steps described above, make sure the adult is p roperly seated and restrained at one of
the rear seating positions.
- Have the airbag system inspected by your
authorized Aud i dealer before transporting
anyone on the front passenger seat.
@ Tips
If the capacitive passenger detection system
determines that the front passenger seat is
empty, the frontal airbag on the passenge r
side w ill be tu rned off, and the
PASSENGER
AIR BAG OFF
11;; light will stay on.

Repair , care and disposal of the airbags
Parts of the a irbag system are installed at many
different places on your Audi. Installing, remov­ ing, servic ing or repa iring a part in an area of the
ve hicle can damage a part of an airbag system
and prevent that system from working properly
i n a collision .
There are some important things you have to
know to make sure that the effectiveness of the
system w ill not be impaired and that discarded
components do not cause injury or pollute the
env ironment.
A WARNING
Improper care, serv icing and repai r proce­
dures can increase the r is k of personal injury
and death by preventing an airbag from de­
ploying when needed or dep loying an airbag
unexpectedly:
-
- Never cover, obstruct, or change the stee r­
ing wheel horn pad or airbag cover or the in­
strument pane l or modify them in any way.
292
- Never attach any objects s uch as c upholders
or telephone mountings to the surfaces cov­
ering the a irbag un its.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth 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 canno t deploy and p rotect
properly.
- Never repair, adjust , 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 a udio eq uipment,
cellular telephones and C B radios, etc.)
m ust be perfo rmed by a qualified techn ician
who has the training and specia l equipment
necessary.
- For any work on the airbag system, we strong ly recommend that you see your au­
thorized A udi dealer or qualified workshop.
- Never modify the front b umper or parts of
the vehicle body.
- Always make sure that the side a irbag can
inflate w ithout interference:
- Never install seat covers or replacement
u pholstery over the front seatbacks that
have not been specifically approved by
A udi.
- Never use additional seat c ushions that
cover the areas where the side airbags in­
flate.
- Damage to the orig inal seat cove rs or to
the seam in the area of the s ide airbag
module mus t always be repaired immedi­
ate ly by an autho riz ed Au di dealer.
- The a irbag system can deploy on ly once. Af­
ter an airbag h as been deployed, i t m ust be
repla ced with new replacement parts de­
signed and approved espec ia lly for your
Audi model version . Replacement of com­
plete airbag systems or airbag components
must be perfo rmed by qua lified workshops
only. Make su re that any airbag service ac­
tion is entered in your A udi Warranty

Child safety
-Always make sure that the PASSENGER
AIR BAG
OFF~; light comes on and stays
on all the time whenever the ignition is
switched on .
- If the
PASSENGER AIR BAG OFF~; light
does not come on and stay on, immediate­
ly install the forward-facing child seat in a
rear seating position and have the airbag
system inspected by your authorized Audi
dealer.
- Always buckle the child seat firmly in
place even if a child is not sitting in it. A
loose child seat can fly around during a
sudden stop or in a collision.
-Always read and heed all WARNINGS
whenever using a child restraint in a vehi­
cle ¢
page 268, Safety belts , ~ page 2 77,
Airbag system and ~ page 302, Impor­
tant information.
(D Tips
Always replace child restraints that were in­
stalled in a vehicle during a crash. Damage to
a child restraint that is not visible could cause
it to fail in another collision situation.
Advanced front airbag system and children
Your vehicle is equipped with an "Advanced Air­
bag System" in compliance with United St ates
Federal Motor Vehicle Safety Standard (FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 208 as applicable at the time
your vehicle was manufactured.
The Advanced Airbag system in your vehicle has
been certified to meet the "low-risk " require­
ments for 3- and 6-year old children on the pas­
senger side and small 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 Stand­
ard, to turn off the front airbag for infants up to 12 months who are restrained on the front pas-
304
senger seat in child restraints that are listed in
the Standard.
Even though your vehicle is equipped with an Ad­
vanced Airbag system, all children, 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 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
larger child in a rearward-facing seat.
The vehicle's Advanced Airbag System has a ca­ pacitive passenger detection system in the front
passenger seat cushion that can detect the pres­
ence of a baby or a child in a child restraint sys­
tem on this seat.
The capacitive passenger detection system regis ­
ters the changes that result in an electrical field
when a child, a child restraint , and a baby blanket
are on the front passenger seat. The change in
the measured capacitance due to the presence of
a child, a child restraint, and a baby blanket on
the front passenger seat is related to the child
restraint system resting on the seat. The meas­
ured capacitance of a child restraint system var­
ies depending on the type of system and specific
make and model.
The electrical capacitance of the various types, makes, and models of child restraints specified
by the U.S.National Highway Traffic Safety Ad­
ministration (NHTSA) in the relevant safety
standard are stored in the Advanced Airbag Sys ­
tem control unit together with the capacitances
typical of infants and a 1-year old child. When a
child restraint is used on the front passenger
seat with a typical 1 year-old infant, the Ad­
vanced Airbag System compares the capacitance
measured by the capacitive passenger detection
system with the data stored in the electronic con­
trol unit .

make sure that it has been certified to meet Safe -
ty Standards and has been certified by its

Wheels
-The tire must flex more if the tire pressure is too low or if
the vehicle speed or load are
too high . This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
-Incorrect tire pressure in­ creases tire wear and has a
negative effect on driving and
braking behavior, which in­
creases the risk of an accident.
(D Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
Tire pressure table
Please note that the information
contained in the following table
was correct at the time of print­
ing, and the information is sub­
ject to change. If there are differ­
ences between this information
and the tire pressures specified
on the label on the driver's side 8-
pillar, always follow the specifica­
tion on the 8-pillar label
¢ page 351, fig. 284.

(i} For the sake of the environment
-Tire pressure that is too low
increases fuel consumption.
-Fuel consumption may also in­
crease when driving with the
comfort tire pressure is se­
lected .
(D Tips
Audi recommends using the
tire pressure specified for a
normal load
¢ table on
page 353
or for a full load
when the vehicle is partially loaded.
Make sure that the tire designa­
tion on your tire matches the des­ ignation on the tire pressure label
and the tire pressure table.
The following table lists recom­ mended tire pressures in cold
tires according to the load and
the size of the tires installed.

Wheels
check you r tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi­
cantly under-inflated tire causes the tire to over­
heat and can lead to t ire failure. Under-inflation
also reduces fuel efficiency and t ire tread life,
a nd may affect the veh icle's handling and stop ­
p ing ability .
Please note that the TPMS is not a substit ute for
proper tire maintenance, and it is the driver's re­
sponsib ility to ma inta in correct tire pressure,
even if under-inflation has not reached the level
to tr igger illum inat io n of the TPMS low tire p res­
sure tellta le.
Your veh icle has also bee n eq uipped w ith a TPMS
malfunct ion i nd icator to indicate when the sys­
t e m is not operat ing properly. The TPMS ma l­
f u nction indicator is comb ined w ith the low tire
p ress ure tellt ale. Whe n the system dete cts a
malfunct ion, the te lltale will flash for approxi­
mate ly one min ute and then remain continuo usly
i l luminated. This sequence will continue upon
subseq uent veh icle start- ups as long as the ma l­
function ex ists .
When the malf unctio n indicator is ill uminated,
the system may not be able to detect or signa l
low tire pressure as intended . TPMS ma lf u nctions
may occur for a variety of reasons, including the
installation of replacement or alternate t ires or
wheels on the vehicle that prevent the TPMS from functioning prope rly . Always c heck the
TPMS malfunct ion tellta le afte r replacing one o r
mo re t ires o r whee ls on your ve hicle to e nsu re
t hat the repla cement or altern ate t ires and
wheels a llow the TPM S to con tinue to function
p roperly.
If the tire pressure monitoring indicator
appears
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction .
Using the ABS sensors, the tire pressure mon itor­
ing system compares the tire tread circ umfer­
ence and vibration cha racteristics of the individu­
a l tires. If the pressure changes in one or more
tires, this is ind icated i n the instrument cluste r

display with an indicato r light RE and a message .
If only one tire is affected, the location of that
t ir e will be indicated.
