\.J ' 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.
- Always install rear-facing child seats on the
rear seat.
- If you must install a rearward facing child
seat on the front passenger seat because of
exceptional circumstances and the
PASSEN­
GER AIR BAG OFF
light does not come on
and stay on, immediately install the rear­
facing child seat in a rear seating position and have the a irbag system inspected by
your 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 cup holders, 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-
-
Airbag system
bag during braking or in a sudden maneu ­
ver. Objects near the airbags can become
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 .

\.J - -If, in exceptional circumstances, you must
install a forward-facing child restraint on
the front passenger seat, always move the
seat into its rearmost position 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 position.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the time
whenever the ignition is switched on.
_& WARNING
- If the PASSENGER AIR BAG OFF light does
not go out when an adult is sitting on the
front passenger seat after taking the steps
described above, make sure the adult is
properly seated and restrained at one of the
rear seating positions .
- Have the airbag system inspected by your
Audi dealer before transporting 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 will be turned off, and the
PASSENGER
AIR BAG OFF
light will stay on.
Repair , care and disposal of the airbags
Parts of the airbag system are installed at many
different places on your Audi. Installing , remov­
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 working properly
in a collision.
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.
_& WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal injury
and death by preventing an airbag from de-
-
Airbag system
ploying when needed or deploying an airbag
unexpectedly :
- Never cover, obstruct, or change the steer­
ing wheel horn pad or airbag cover or the in­
strument panel or modify them in any way.
- Never attach any objects such as cup holders
or telephone mountings to the surfaces cov­
ering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one mois­
tened with plain water. Solvents or cleaners
could damage the airbag cover or change
the stiffness or strength of the material so
that the airbag cannot deploy and protect properly.
- Never repair, adjust, or change any parts of
the airbag system.
-All work on the steering wheel, instrument
panel, front seats or electrical system (in­
cluding the installation of audio equipment,
cellular telephones and CB radios , etc.)
must be performed by a qualified technician
who has the training and special equipment
necessary.
- For any work on the airbag system, we
strongly recommend that you see your au­
thorized Audi dealer or qualified workshop.
- Never modify the front bumper or parts of
the vehicle body.
- 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 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

(D Note
Replace lost valve caps to re­
duce the risk of damage to the

@ For the sake of the environment
Tire pressure that is too low in­
creases fuel consumption.
(D Tips
Audi recommends using the
tire pressure specified for a
normal load
q table on
page 223
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
As an added safety feature, your vehicle has been
equipped with a tire pressure mon itor ing system
(TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant­
ly under-inflated . Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your 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 tire failure. Under-inflation
also reduces fuel efficiency and ti re tread life,
and may affect the vehicle's handling and stop­
ping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure,
even if under- inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low tire
pressure telltale . When the system detects a
malfunction, the telltale will flash for approxi ­
mately one m inute and then remain cont inuously
illuminated . This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists .
When the malfunct ion indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.

Tire pressure monitoring system
Applies to: vehicles with Tire Pressure Monitoring System in­
dicator
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Fig. 194 Instrumen t cl uster : indicator l ig ht with me ssage
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread circumfer­
ence and vibration characteristics of the individu­
al tires. If the pressure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light
Rt] and a message.
If only one tire is affected, the location of that
tire will be indicated.
The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle
¢ page 231. The tire pressure mon i­
toring system only monitors the tire pressure you have stored . Refer to the tire pressure label for
the recommended tire pressure for your vehicle
¢page 221, fig. 193.
Tire tread circumference and vibrat ion character­
istics can change and cause a tire pressure warn­
ing if :
- the tire pressure in one or more tires is too low.
- the tire has structural damage.
- the tire was replaced or the tire pressure was
changed and it was not stored¢

Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsib ility to ma intain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your veh icle has also been equ ipped with a TPMS
malfunction indicator to indicate when the sys ­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low tire
pressure telltale . When the system detects a
malfunction, the telltale will flash for approxi­ mately one minute and then remain cont inuously
illum inated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists.
When the malfunct ion indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS ma lfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS

Description
A pp lies to: ve hicles w ith tire p ressure monitoring system
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
The system uses sensors that measure the tem ­
perature and pressure in the tires . The data is
sent from these sensors to the contro l module by
radio frequency.
The Tire Pressure Monitoring System shows the current pressures and temperatures of the tir es
in the Infota inment system
c:> page 232. It also
compares the current t ire pressures with the
stored tire pressu res and gives a warning in the
d river information system if the tire pressure is
different from what is stored
r:';> page 233.
232
The system does not detect if the stored tire
pressures match the recommended tire pres­
sures. You must store the tire pressures again
c:> page 233:
-every time the tire pressures change, for exam ­
ple when the load in the vehicle changes,
- after replacing a tire, or
- if wheels with new whee l sensors are used.
_&. WARNING
- The tire pressure monitoring system assists
the driver in monitoring tire pressures. The
driver is responsib le for having the tires in­
flated to the correct pressure.
- Do not change the tire pressure when the
temperature of the tire is high. This could
result in serious damage to the tire and
even cause the tire to burst, increasing the
risk of an accident.
-A tire with low pressure flexes more. This heats the tire up too much. This could cause
the tread to separate and even cause the
tire to burst, increasing the risk of an acc i­
dent.
- The tire pressure monitoring system does
not warn about damage or defects in the
tire construct ion that could cause the tire to
burst, for examp le. Inspect your tires reg u­
larly.
(D Tips
- If tires are replaced, the sensors/valves do
not need to be removed or replaced. Just re­
placed the va lve stem and, if necessary, the
valve and the wheel electronics.
If you have
questions, see your authorized Audi dealer
or authorized Audi Service Facility.
- An incorrect display or a malfunction in the
tire pressure monitoring system can occur
after using the tire mobility kit. Have the
sensors rep laced by an authorized Audi
dealer or author ized Audi Service Facility.

Malfunctions
Appl ies to : vehicles wi th tire pressure mo nito rin g system
If the Tire Pressure Monitoring System is not
avai lable, the
mm indicator light appears in the
driver information system. The
Rt] indicator light
also blinks for approximately one minutes each
time the ignition is switched on. The tire pressure
monitoring system cannot be selected in the In­
fotainment system. The following are examples
of situations that could cause a malfunction:
- If the message appears at the end of the adap­
tation phase, the system cannot detect the
wheels installed on the vehicle. This may result
from one or more wheels being installed with­ out wheel sensors or with incompatible wheel
sensors.
- A wheel sensor or another component has
failed.
- Using snow chains can affect the function of
the system because of the shield ing effect of
the cha ins.
- The tire pressure monitoring system is not
available due to a malfunction .
- Transmitters with the same frequency, such as
headphones or remote-controlled devices, may
cause a temporary system malfunction due to
the strong electromagnetic field.
The
mm indicator light turns off once the Tire
Pressure Monitoring System is available again.
If
you cannot correct the malfunction and the mm
