& WARN ING (continued )
• Always make sure that the side airbag can inflate without inter­
fe rence :
- Never install seat covers or replacement upholstery over the
front seatback s that have not been spe cifically approved by
Audi.
- Never use additional seat cushions that cover the areas
where the side airbags inflate .
- 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 be activated only once. After an airbag
ha s inflated , it must be replaced by an authorized Audi de aler or
qualified technician who has the technical information , training
and special equipment necessary .
• The airbag system can be deployed only once. After an airbag
has been deployed , it must be repla ced with new repla cement
parts designed and approved especially for your Audi model
version . Replacement of complete airbag systems or airbag
components must be performed by qualified workshops only .
Make sure that any airbag service action is entered in your Audi
Warranty
& Maintenance booklet under AIRBAG REPLACEMENT
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 pyrotechni c circuit interrupter must only be
performed by a qualified dealer -risk of an accident!
- If the vehi cle or the circuit inte rrupter is scrapped , all appli ­
cable safety precautions must be followed. •
Other things that can affect Advanced Airbag
performance
Changing the vehic le 's suspens ion system can change the way that
th e Adva nced Air bag Syste m performs in a c rash. Fo r example,
using tire -ri m co mbinations not approved by Audi, lowering the
veh ic le, c hang in g the st if f ness o f th e suspe nsio n, incl uding th e
spr ings, suspension struts, shock absorbers etc. can change the
f o rces t hat a re m easured by the a irba g se nsors and se nt to the elec ­
tronic control unit. Some suspension changes can, for example,
i ncrease the fo rce level s meas ure d by the senso rs and make the
a irbag system dep loy in crashes in which it wou ld not d ep loy if the
changes ha d no t been made . O th er ki nds of changes may red uce
th e force levels measured by the sensors and preve nt the airbag
fro m deploying w hen it sh ould.
Th e senso rs in th e sa fety belt buc kle fo r the dr iver a nd fro nt
passenger seat te ll the e lectronic control modu le if the safety belt is
l a tc h ed or not. If th e sa fe ty belt is being use d, th e front airbag wi ll
deploy at a slightly higher rate of vehic le dece leration than if the
sa fe ty be lt is n ot b ein g use d. Th ere fore, i n a partic ula r co llisi on, i t is
possible that an airbag wi ll not deploy at a seating position where
th e sa fe ty be lt is bei ng us ed bu t wi ll infl ate at the position w here the
safety be lt is not being used. It is important that nothi ng interfere
with the safety belt buc kles so that the sensors can send the co rrect
i nformatio n about safety belt use to t he electronic control unit.
& WARNING
Changing the vehicle's suspension including use of unapproved
tire -rim combinations can change Advanced Airbag performance
and increase the risk of serious personal injury in a crash.
• Never install suspension components that do not have the
same pe rformance characteristics as the components originally
installed on your vehicle.
• Never use tire -rim combinations that have not been approved
by Audi. ..

ture. For example, the numbers 2209 mean that the tire was
produced in the 22th week of 2009. The other numbers are
marketing codes that may or may not be used by the tire manufac­
turer. This information is used to contact consumers if a tire defect
requires a recall.
Tire ply composition and materials used
The number of plies indicates the number of layers of rubber-coated
fabric in the tire. In general, the greater the number of plies, the
more weight a tire can support. Tire manufacturers also must indi­
cate the materials in the tire, which include steel, nylon, polyester,
and others .
Maximum Load Rating
This number indicates the maximum load in kilograms and pounds
that can be carried by the tire.
Tire quality grading for treadwear, traction, and
temperature resistance
Tread wear, traction and temperature grades => page 249.
Maximum Permissible Inflation Pressure
This number is the greatest amount of air pressure that should ever
be put in the tire under normal driving conditions.
Replacing tires or rims on vehicles equipped with tire
pressure monitoring system*
The wheels on your vehicle are equipped with a sensor which
constantly monitors the air pressure inside the tire, and then trans­
mits this information to the tire pressure monitoring system *. If you
are going to replace the wheel rims on your vehicle, make sure the
new rims also have these sensors . The sensors must be compatible
with the tire pressure monitoring system * on your vehicle.
If the sensors are to be installed on different rims , the seal, washer ,
and valve cap for each sensor must be replaced.
If you install rims, which do not have the sensors, or have sensors
which are not compatible, then the tire pressure monitoring system* will not work properly.
In this case, the tire pressure moni­
toring system * would not be able to monitor the tire pressure or
warn you if it is necessary .
• The battery inside of the tire pressure sensor has a limited
service life.
• Always drive with the valve stem caps securely mounted. We
recommend using factory installed valve stem caps. Ask your autho­
rized Audi dealer to replace lost valve stem caps.
The installation of replacement tires with steel cord body plies in
the tire sidewall may cause malfunction of the tire pressure moni­
toring system*, and is not recommended (cord material information
in molded on the tire sidewall) .
Always check your tire pressure monitoring system* indicator after
replacing one or more tires on your vehicle. If the tire pressure
monitoring system* indicator flashes, or is on, your system is not
working properly. Your replacement tire might be incompatible with
your tire pressure monitoring sys tem* , or some component o f the
tire pressure monitoring system* may be damaged.
& WARNING
• Using incorrect or unmatched tires and/ or wheels or improper
tire and wheel combinations can lead to loss of control, collision
and serious personal injury.
• Always use tires, rims and wheel bolts that meet the specifica­
tions of original factory-installed tires or other combinations that
have been specifically approved by the vehicle manufacturer .
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds.
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control. .,_
