A WARNING
1
Improper care, servicing and repair proce­
dures can increase the risk of personal in ­
jury and death by preventing an airbag from deploying when needed or deploying an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel horn pad or airbag cover
or the instrument panel or modify them
in any way .
- Never attach any objects such as cup
holders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft , dry cloth or one
moistened 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 de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system.
- All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including 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
authorized Audi dealer or qualified work­
shop.
- 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 replace­
ment upholstery over the front seat­
backs that have not been specifically
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 air­ bag module must always be repaired
Airbag system 123
immediately by an authorized Audi
dealer.
- The airbag system can be activated only
once . After an airbag has inflated, it
must be replaced by an authori zed Audi
dealer 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 replaced with new replace­
ment parts designed and approved espe­
cially for your Audi model version . Re­
placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only. Make sure that any airbag service action
is entered in your Audi Warranty
& Main­
t enance booklet under
AIRBAG REPLACE­
MENT RECORD .
-For safety reasons in severe accidents,
the alternator and s tarter are separa ted
from the vehicle battery with a pyrotech ­
nic circuit interrupter .
- Work on the pyrotechnic circuit inter­
rupter must only be performed by a
qualified dealer - risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped , all applicable safety pre­
cautions must be followed.
@ For the sake of the environment
Undeployed airbag modules and preten ­
sioners might be classified as Perchlorate
Material - special handling may apply, see
www .dtsc .ca. gov/hazard o u swaste/ per-
ch [orate . When the vehicle or parts of the
restraint system including airbag modules
and safety belts with pretensioners are
scrapped, all applicable laws and regula­
tions must be observed. Your authorized
Audi dealer is familiar with these require­
ments and we recommend that you have
your dealer perform this service for you.

124 Airbag system
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem performs in a crash. For example, using
tire-r im combinations not approved by Audi,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion strut s, shock absorbers 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 measured 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
changes may reduce the force levels meas­
ured by the sensors and prevent the airbag
from deploying when it should .
The sensors in the safety belt buckle for the
driver and front passenger seat tell the elec­
tronic control module if the safety belt is
latched or not .
If the safety belt is being used,
the front airbag will deploy at a slightly high­ er rate of vehicle deceleration than if the safe­
ty belt is not being used. Therefore, in a par­
ticular collision, it is possible that an airbag
will not deploy at a seating position where the
safety belt is being used but will inflate at the
position where the safety belt is not being
used.
It is important that nothing interfere
with the safety belt buckles so that the sen­
sors can send the correct information about
safety belt use to the electronic control unit .
A WARNING
Changing the vehicle's suspension includ­
ing use of unapproved tire-rim combina­
tions can change Advanced Airbag per­
formance and increase the risk of serious
personal injury in a crash.
- Never install suspension components
that do not have the same performance
characteristics as the components origi­
nally installed on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.
A WARNING
-Items stored between the safety belt
buckle and the center console can cause
the sensors in the buckle to send the
wrong information to the electronic con­
trol module and prevent the Advanced Air­
bag System from working properly.
- Always make sure that nothing can inter­
fere with the safety belt buckles and that
they are not obstructed.
Knee airbags
· Description of knee airbags
The knee airbag system con provide supple­
mental protection to properly restrained
front seat occupants.
Fig. 124 Drive r's airbag
The driver knee airbag is in the instrument
panel underneath the steering wheel
~ fig . 124, the airbag for the passenger is at
about the same height in the instrument pan­
el underneath the glove compartment.
The knee airbag offers additional protection
to the driver's and passenger's knees lower
thigh areas as a supplement to the protection
by the safety belts.
If the front airbags deploy, the knee airbags
also deploy in frontal collisions when the de­
ployment threshold stored in the control unit
is met
~ page 118, More important things to
know about front airbags.
In addition to their normal safety function,
safety belts help keeping the driver or front
passenger in position in a frontal collision so ..,.

Because tec hnical changes may be made to
vehicle equ ipment dur ing the model yea r, al­
ways compare the tire size designation on the
tire pressure labe l on you r vehi cle w it h the
tires on your vehicle. Ma ke s ure that the ti re
size information on the veh icle label is the
same as the size of the tires on the vehicle.
This is especially important if the vehicle be­
longs to someone else or you bought the vehi­
cle with different rims/tires or you bought the
vehicle as a previously owned vehicle.
Remember, your safety and that of your pas­
sengers also depends on mak ing sure that
load limits are not exceeded. Vehicle load in­
cludes everybody and everything in and on the
vehicle . These load lim its are technically refer­
red to as the vehicle's G ross Vehicle We ight
Rati ng ("GVWR"). The G ross Ax le Weight Rat­
i ng ("GAWR") is the max imum load that can
be app lied at each o f the veh icle's two axles.
The G ross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance stic ker labe l located either
on the driver's side B-pillar. The tire pressure
labe l on your Audi lists the maximum com­
b ined weight of all of the occupants and lug­
gage or other cargo that the veh icle can carry.

.&_ WARNING
Overloading a vehicle can cause loss o f ve­
h icle cont ro l, a crash o r other accident, se ­
r ious pe rsonal injury, and even death.
- Ca rrying more we igh t than your veh icle
was designed to car ry wi ll prevent the
vehicle from handling properly and in­
crease the risk of a loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
veh icle w ith in a safe distance.
- Tires on a vehicle that has been over load­
ed can fail s uddenly caus ing loss of con­
trol and a crash.
.&_ WARNING
- Incorrect tire pressures and/or underin­
flation can lead to a serious or fatal acci­
dent.
- Inco rrect tire pressures and/or underin­
f lation cause increased tire wear and can
affect the handling of the vehicle.
- Inco rrect tire pressures and/or underin­
f lation can a lso lead to s udden t ire fail­
ure, including a blowout and sudden de­
fl ation, ca using loss of veh icle cont ro l.

190 Tire s and wheel s
wheels you have to adjust t he tire pressures
on all w heels .
A WARNING
Incorrec t tire pressures and/or underinfla ­
t ion can lea d sudden tire failure, loss of
contro l, collision, ser ious personal injury
or even death.
- When the warning symbo l
RI] appears in
the instrument cluster, stop and inspect
the tires .
- Incorrect tire pressure and/or underinfla­
t io n can cause increased t ire wear and
can affect the handling of the ve hicle and
stopp ing ability .
- Incorrect tire pressures and/or underin­ fla tion can also lead to sudden tire fa il­
ure, incl uding a blowo ut and sudden de­
fla tion, causing loss of vehicle control.
- T he d river is responsible for the cor rect
t ire pressures fo r all tires on the vehicle .
T he ap plic a b le p ress ure v alues are locat­
ed on a st ic ker on the drive r's side 8-pil­
lar.
- O nly when all t ires on the vehi cle ar e fi l­
led to the correct pressure, the tire pres ­
sure monitoring system can wor k co r­
rect ly .
- Th e use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver
observe the specif ied tire pressure va lues
for the tires and the correct pressures for
the funct ion of the tire pressure mo nitor­
ing system .
- Always inflate tires to the recommended
and correct tire pressure befo re drivi ng
off .
- Driv ing with under inflated tires bend
more, lett ing them get too ho t res ulting
in t read separation, sudden t ire fail ure
and loss of control.
- Excess ive speed and/ove rloading can
cause heat bui ld-up, sudden t ire fa ilu re
and loss of control.
- If the t ire pressur e is too low or too high,
the ti res w ill wea r pre matu rely a nd the
vehicle will not h and le we ll. -
If the tire is not flat and you do not have
to change a wheel immediately, drive at
red uced speed to the nearest service sta­
tion to check the t ire pressure and add
air as req uired.
(D Note
Driving without valve stem caps can ca use
damage to the tire valves. To prevent this,
a lways make sure that factory installed
valve stem caps o n all whee ls are sec urely
mounted o n the valve.
@ For the sake of the environment
Underinflated tires w ill also increase the
fuel consum ptio n.
Tires and vehicle load limits
T he re a re lim its to the amount of load o r
weight tha t any veh icle a nd any tire can ca rry .
A vehi cle that is overloaded will no t handle
well and is mo re d iff icu lt to stop . Ove rloading
can not only lead to loss of vehicle control,
but can also damage important parts of the
vehicle and can lead to sudden tire fa ilure, in­
clud ing a b lowout and sudden deflation that
can cause the vehicle to cras h.
Your safety and that of your passengers also depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the veh icle . These
load lim its are technically referred to as the
vehicle 's
Gro ss Vehicle Weight Rating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, all facto ry installed accessor ies, a full
tank of fuel, o il, coolant and other fluids plus
max imum load . T he max imum load includes
t h e nu mbe r of p assenge rs t hat the vehicle is
i n tended to c arry ("seat ing c apac ity") wi th an
ass umed we ight of 150 lbs . (68 kg) for each
passenger at a designated seating position
and the total weight of any luggage in the ve -
hicle. ..,_

202 Tire s and whee ls
- The tire pressure monitoring system
helps the driver to keep an eye on tire
pressures. But the driver st ill has the re­
spons ibility for maintaining the correct
tire pressure.
- Tire pressure must only be adjusted
when the temperature of the tires is
about the same as ambient air tempera­
ture.
- When t ires are replaced, the sensors and
valves should not be exchanged . The
valve core, nut, valve sealing and seal
washer (rep lacement kit) needs to be re­
placed. If necessary, the valve and the
whee l electronics have to be rep laced.
- The tire pressure monitoring system on
your Audi was calibrated us ing tires w ith
"RO" identification. We recommend us­
ing these tires.
- If you should put different whee ls and
ti res on yo ur vehicle (e.g. w inter wheels
and tires), yo u m ust be certain that the
whee ls and tires are compatible with the
tire pressure monitoring system . Other­
wise the system w ill reg ister a ma lfunc­
tion and a fault message will be d is­
played . For more information, contact
your authorized Audi dealer .
