Repair, care and disposal of the airbags
Parts of the airbag 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
veh icle 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 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 steer ­
ing wheel horn pad or airbag cover or the in­
strument pane l or modify them in any way.
284
- Never attach any objects such as cupholders
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 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 e lectr ica l system ( in­
cluding the installation of a udio eq uipment,
cellular telephones and CB radios, etc.) m ust be performed 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 Audi 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 without interference:
- Never install seat covers or replacement
upholstery 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 rized Aud i dealer .
- The a irbag sys tem can deploy on ly once. Af­
ter an airbag has been deployed, it m ust be
replaced with new replacement parts de­
signed and approved especia lly for your
Audi model version . Replacement of com­
plete airbag systems or airbag components
must be performed by qua lified workshops
only . Make sure that any airbag service ac­
tion is entered in your Audi Warranty

Tires and vehicle load limits.
-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.

Wheels
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 minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists.
When the malfunction 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.
If the tire pressure monitoring indicator
appears
Applies to: vehicles with Tire Pressure Monitoring System in­
dic ato r
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 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
RI] 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
348
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle ~
page 349. The tire pressure moni­
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 340, fig . 272.
Tire tread circumference and vibration character­
istics can change and cause a tire pressure warn­
ing if:
- the tire pressure in one or more tires is too low
- the tires have structural damage
- the tire was replaced or the tire pressure was
changed and it was not stored

several minutes after storing the pressures until
the indicator light turns off . If the indicator light
does turn off or turns on again after a short peri­
od of time, drive to an authorized Audi dealer or
authorized Audi Service Facility immediately to
have the malfunction corrected.
& WARNING
- If the tire pressure indicator appears in the
display, reduce your speed immediately and
avoid any hard steering or braking maneu­
vers. Stop as soon as possible and check the
tires and their pressure.

-The driver is responsib le for maintaining the
correct tire pressure. You must c heck the
