Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con­
ditions. However, in winter we recommend using
winter or all season tires on
all four wheels, be­
cause this will improve the
broking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
¢ page 2 70, Snow chains.
Replacing tires
For vehicles with all wheel drive, only whee ls with
the same rolling circumference should be used .
Avoid using tires with different tread depths
¢ page 262, New tires or wheels.
Offroad vehicle?
Your Aud i is not an offroad vehicle - there is not
enough ground clearance. For this reason, avoid
difficult terrain.
_&. WARNING
-Also, in vehicles with all wheel drive, adapt
your driv ing style to the current road and
t ra ffic conditions. Do not let the increased
safety provided tempt you into taking risks,
because this increases the r isk of an acci­
dent.
- The braking ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two wheel drive vehi­
cle. Do not be tempted to accelerate to a
high speed when the road is slippery, be­
cause this increases the risk of an accident.
- Note that on wet streets, the front wheels
can "hydroplane" if driving at speeds that
are too high. Unlike front whee l drive
vehicles, the eng ine does not rev highe r sud­
denly when the vehicle begins hydroplaning.
For this reason, pay attention to the road
conditions regardless o f your speed.

Airbag syste m
-Always install rear -facing child seats on the
rear seat.
- If you must install a rearward facing chi ld
seat on the front passenger seat because of
exceptional c ircumstances and the
PA SSEN ­
G ER 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 airbag system inspected by
you r Audi dealer.
_& WARNING
Objects between you and the a irbag w ill in­
crease the risk of in jury in a crash by interfer­
ing with the way the airbag unfo lds or by be­
ing pushed into yo u as the airbag 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 front passenger seat . Objects could
move into the area of the front airbags du r­
ing brak ing or other sudden maneuver and
become dangerous projectiles that can
cause serious personal injury if the a irbags
inflate.
- Never place or attach accessor ies or other
objects (such as cup holders, te lephone
brackets, large, heavy or bulky objects) on
the doors, over or near 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, espe cially
when the airbags inflate.
- Never recline the front passenge r's seat to
t ransport 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 projectiles and cause injury, particularly
when the seat is reclined .
- Never place or transport objects on the
front passenger seat. Objects on the front passenge r seat could cause the capac itive
sensor in t he 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
208
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 t urned 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 o n
the front passenge r seat that will cause the
capacitive passenge r de tection system in
the sea t to signal to the Airbag System tha t
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 than the person act ually
sitt ing 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 diffe rent from the way it would have
wo rked without the object on the seat.
- Never til t the front passenger seat backrest
forward when the vehicle is mov ing . An in­
flating airbag wi ll force t he bac krest back­
ward and can injure rear seat occup ants .
_& WARNING
The fine dus t created when airbags deploy can
cause breathing prob lems for people with a
h istory of asthma or other breathing condi ­
tions.
- To reduce the r isk of breathing problems,
those with asthma o r other respiratory con­
ditions sho uld get fresh ai r right away by
getting out of the vehicle or opening win ­
dows or doors.
- If you are in a co llision in which airbags de­
ploy, wash your hands and face with m ild
soap and water before eating.
- Be carefu l not to get the dust into your eyes,
or into any cuts or scratches .
-If the residue shou ld get into your eyes,
flush them w ith water .

Airbag syste m
Make sure that the PASSENGER AIR BAG

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
Audi dealer befo re t ransporting 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

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.
212
- Never attach any objects s uch as c up ho lders
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
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 alway s 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

{D) Tips
Always replace child restraints that were in­
stalled in a vehicle dur ing 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 a front "Advanced
Ai rbag System" in compliance with United States
F edera l Motor Vehicle Safety Standard ( FMVSS)
208 as applicable at the time your vehicle was manufactured.
The Advanced Airbag system in your vehi cle 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
"s uppress io n " req uiremen ts of the Safety Stand­
ard, to turn of f the front airbag for infants up to
12 months who are restrained on the front pas­
senger seat in chi ld restraints that are listed in
the Standard.
E ven though your vehicle is equipped with an Ad­
vanced Ai rbag system, all children, especially
those 12 years and younger, should always r ide
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 safety
child to ride. The front seat is not the safest place
for a chi ld in a forward-facing chi ld safety seat . It
can be a very dangerous place for an infant or a
larger ch ild in a rearward-facing seat.
T he vehicle's Advanced A irbag 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 ch ild 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 b lanket
are on the front passenger seat. The change in
the measured capacitance due to the presence of
a child, a ch ild restraint, and a baby blanket on
the front passenger seat is related to the child
restraint system resting on the seat . Th e meas­
ur ed capacitance of a child restraint system var­
ies depending on the type of system and specific
make and mode l.
T he elect rical capacitance of the various types,
makes, and models of child restra in ts specified
by the U.S .National Highway Traff ic Safety Ad­
ministration (NHTSA) in the relevant safety
standard are stored in the Advanced Airbag Sys­
tem control unit together with the capacitances
typ ica l of infants and a 1-year old child. When a
child restraint is used on the front passenger
seat w ith a typical 1 year -old infant, the Ad­
vanced Airbag System compares the capacitance measured by the capacitive passenge r detection
system with the data stored in the electronic con­
trol unit.
Child restraints and Advanced front airbag
system
Regardless of the ch ild restraint that you use,
make sure that it has been certified to meet Unit­
ed States Federal Motor Vehicle Safety Standards
and has been certified by its manufacturer for
use with an a irbag. Always be sure that the child
r estra int is properly installed at one of the rear
seating positions.
If in except ional circumstances
you must use it on the front passenger seat, care­
f ully read all of the information on child safety
and Advanced Airbags and heed all of the .,.

-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

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 System
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 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 Infotainment system
display w ith an indicator light
RE 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
c::;, page 274 . 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

- The driver is responsible for maintaining the
correct tire pressures . You must check the
tire pressures regularly .
- Under certain conditions (such as a sporty
driving style, winter conditions or unpaved
roads), the pressure monitor indicator may
be delayed.
- Do not use run-flat tires on your vehicle . Us­
ing them when not permitted can lead to
vehicle damage or accidents.
