By using all wheel d rive, yo ur vehicle has good
forward motion with standard t ires in winter con­
ditions. However, in winter we recommend using
wint er or all season t ires on all four wheels, be­
cause this will improve the braking effect.
Snow chains
If
t h ere are snow cha in laws, snow chains must
a lso be used on vehicles with a ll wheel drive
¢ page 221, Snow chains.
Replacing tires
For vehi cles w ith all whee l dr ive , only whee ls w ith
the same rolling circumferen ce s hou ld be used .
Avoid using tires with different tread depths
¢ page 212, New tires or wheels .
Offroad vehicle?
Your Audi is not an offroad vehicle -there is not
enough g round clearance. For this reason, avo id
d ifficult terrain .
_& WARNING
-Also, in vehicles with a ll wheel drive, adapt
yo ur dr iv ing style to the cu rrent road and
traff ic conditions . Do not let the increased
sa fety provided tempt you into taking risks ,
because th is increases the r isk of an acci­
dent .
- The braking ability of your veh icle is limited
to the tract ion of t he wheels . In this way, it
is not diffe rent from a two whee l dr ive vehi ­
cle. Do not be tempted to accelerate to a
hig h speed when t he road is slippe ry, be­
ca use this increases the risk of a n accide nt .
- Note that on wet streets , the fro nt wheels
can "hyd roplan e" if d riving at speeds that
are too hig h. Unlike front whee l drive
vehicles, t he eng ine does not rev highe r su d­
den ly when the vehicle begins hydroplaning .
For this reason, adapt your speed to the
road conditions to reduce the risk of an acc i­
dent.

" N .... 0 00 \,;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 airbag 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.

" N .... 0 00 \,;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.
A 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.
A 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
161

Airbag system
must be performed by qualified workshops
only. Make sure that any airbag service ac­
tion is entered in your Audi Warranty
&
Maintenance booklet under AIRBAG RE·
PLACEMENT RECORD .
-For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechn ic circuit
interrupter.
- Work on the pyrotechnic circuit interrupt­
er must only be performed by a qualified
technicians who have the experience, in­
formation and special tools necessary to
perform the work safely.
- If the vehicle or the circuit interrupter is
scrapped, all applicable safety precautions
must be followed .
@ For the sake of the environment
Undeployed airbag modules and pretension­
ers might be classified as Perchlorate Materi­
al
-special handling may apply , see
www .dtsc.ca.gov/hazardouswaste/perchlo ­
rate . When the vehicle or parts of the re­
straint system including airbag modules and
safety belts w ith pretensioners are scrapped,
all applicable laws and regulations must be
observed . Your authorized Audi dealer is fa­
miliar with these requirements and we recom­
mend that you have your dealer perform this
service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash. For example, using tire-rim
comb inations not approved by Audi, lower ing the
vehicle, chang ing the stiffness of the suspension,
including the springs, suspension struts , shock
absorb ers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic control unit . Some suspension changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in which it would not deploy if
the changes had not been made. Other kinds of
162
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy­
i ng when it should .
& WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in­
crease the risk of serious personal injury in a
crash .
- Never install suspension components that do not have the same performance charac­
teristics as the components origina lly instal­
led on your vehicle.
- Never use tire-rim combinations that have
not been approved by Aud i.

Tire pressure monitoring
system
ill General notes
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
bel, you should determine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring 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 tire tread life,
and may affect the vehicle's handling and stop-
ping ability.

T he system uses sensors that measure the tem ­
perature and pressure in the tires . The data is
sent from these sensors to the control module by radio frequency.
T he Tire Pressure Monitoring System shows the
current pressures and temperatures of the tires
in the Infotainment system

compares the current tire pressures with the
stored tire pressures and gives a warning in the
driver information system if the tire pressure is
different from what is
stored ¢ page 226 .
Wheels
The system does not detect if the stored tire
pressures match the recommended tire pres­
sures. You must store the tire pressures again
¢ page 226:
- 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 wheel sensors are used.
_& WARNING
- The tire pressure monitoring system assists
the driver in monitoring tire pressures. The
driver is responsible for having the tires in­
flated to the correct pressure.
- Do not change the tire pressure when the
temperature of the tire is extremely high.
This could result in serious damage to the
tire and even cause the tire to burst, in­
creasing 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 acci­
dent.
- The tire pressure monitoring system does not warn about damage or defects in the
tire construction that could cause the tire to
burst, for example. Inspect your tires regu­
larly.
(D Tips
- If tires are replaced, the sensors/valves do
not need to be removed or replaced . Just re­
placed the valve stem and, if necessary, the
valve and the wheel electronics. If you have questions, see an 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 replaced by an authorized Audi
dealer or authori zed Audi Service Facility.
- For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regulations, see
