Maintenance booklet under
AIRBAG RE­
PLACEMENT RECORD.
- Applies to plug-in hybrid* vehicles: In the
event of a collision where the airbags de­
ploy, the electrical connection to the high
voltage battery is automatically disconnect­
ed. This prevents a short c ircuit.
@) 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 with 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
combinations not approved by Audi, lowering the
vehicle, changing the stiffness of the suspension, including the springs , suspension struts, 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 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
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy­
ing when it should.
A WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in-
.
Airbag system
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 originally instal­ led on your vehicle.
- Never use tire-rim combinations that have
not been approved by Audi.
Knee airbags
Description of knee airbags
Applies to: vehicles with knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front seat
occupants.
Fig. 240 Driver 's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering
wheel¢ fig. 240, the
airbag for the passenger is at about the same
height in the instrument panel underneath the
glove compartment.
The knee airbag offers additional protection to
the driver's and passenger's knees and upper and
lower thigh areas and supplements the protec­
t ion provided by the safety belts.
If the front airbags deploy, the knee airbags also
deploy in frontal collisions when the deployment
threshold stored in the control unit is met
¢ page 2 79, More important things to know
about front airbags .
In addition to their normal safety function, safe­
ty belts help keep the driver or front passenger in
posit ion in a frontal collision so that the airbags
can provide supplemental protection .

occupant safety that nothing should be in their
way when they deploy.
Fully inflated airbags in combination with proper­
ly worn safety belts slow down and limit the oc­
cupant's forward movement and help to reduce
the risk of injury.
Important safety instructions on the knee
airbag system
A ppl ies to: ve hicles with knee a ir b ags
Airbags are only supplemental restraints. Always
wear safety belts correctly and ride in a proper
seating position.
There is a lot that you and your passengers must
know and do to help the safety belts and airbags
to provide supplemental protection .
A WARNING
An inflating knee airbag can cause serious in­
jury . Wearing safety belts incorrectly and im­
proper seating posit ions increase the r isk of
serious personal injury and death whenever a
vehicle is being used .
- The knee airbag system cannot protect you
properly if you are seated too close to any of
the airbag locations. When adjusting their
seat positions, it is important that both the
driver and the front passenger keep their
upper bodies and knees at the following
minimum safe distances :
- at least 10 inches (25 cm) between the
chest and the steering wheel/instrument
panel.
- at least 4 inches (10 cm) between the
knees and the lower part of the instru­
ment panel.
- The risk of persona l injury increases if you
lean forward or to the side, or if the seat is
improperly positioned and you are not wear­
ing your safety belt. The risk increases even
more should the airbag deploy.
- Always make sure that the knee airbag can
inflate without interference. Objects be­
tween you and the airbag can increase the risk of injury in an accident by interfering
-
Airbag system
with the way the airbag deploys or by being
pushed into you as the airbag deploys.
- Never let anybody, especially children or
animals ride in the footwell in front of the
passenger seat. If the airbag deploys, this
can result in serious or fatal injuries.
- Never carry objects of any kind in the foot­
well area in front of the driver's or pas­
senger's seat . Bulky objects (shopping
bags, for example) can interfere with or
prevent proper deployment of the airbag.
Small objects can be thrown through the
vehicle if the airbag deploys and injure you
or your passengers.
- Make sure there are no cracks, deep scratch­
es or other damage in the area of the instru­
ment panel where the knee airbags are lo­
cated.
- If children are incorrectly seated, their risk
of injury increases in a collision

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants .

The side airbags are located in the sides of the
front seat backrests
<=> fig . 242 and the rear back­
rest* facing the doors.
The side airbags installed for the front seating
positions have been designed and certified to
help reduce the risk of injury that can be caused
by airbags when they inflate, particularly when

Child safety
-Always make sure that the PASSENGER
AIR BAG OFF
light comes on and stays on
all the time whenever the ignit ion is
sw itched on.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immediate­
ly install the forward-facing child seat in a
rear seating posit ion and have the airbag
system inspected by your authorized Aud i
dea le r.
- Always buckle the child seat firmly in
place even if a child is not sitt ing in it. A
loose child seat can fly around during a
sudden stop o r in a collision.
- Always read and heed all WARNINGS
wheneve r using a child restraint in a vehi­
cle ~ page 260, Safety belts, ~ page 269,
Airbag system
and ~ page 294, Impor­
tant information .
(D Tips
Always replace child restraints that were in­
stalled in a vehicle during a crash . Damage to
a child restraint that is not visib le could cause
it to fail in another collision situation .
Advanced front airbag system and children
Your veh icle is equipped with a front "Advanced
Airbag System" in compliance w ith United States
Federal Motor Vehicle Safety Standard (FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 208 as applicable at the time
your ve hicle was manufactured.
The Advanced Airbag system in your veh icle has
been cert ified to meet the "low-risk" require­
ments for 3- and 6-year old children on the pas­
senger s ide and small adults on the driver side.
The low risk deployment cr iteria are intended to
reduce the risk of injury through interaction with
the airbag that can occur, for examp le, by being
too close to the steering whee l and instrument
panel when the airbag inflates. In addition, the
system has been certified to comply with the
"suppress ion" requ irements of the Safety Stand­
ard, to turn off the front airbag for infants up to
12 months who are restrained on the front pas-
296
senger seat in child restraints t hat are listed in
the Standard.
Even though your vehicle is eq uipped w it h an Ad­
vanced Airbag system, all childr en, especially
those 12 years and younger, shou ld always ride
in the back seat properly restrained for their age
and s ize. The airbag on the passenger side makes
the front seat a potentially dangerous p lace for a
ch ild to ride. The front seat is not the safest place
for a ch ild in a forward -facing ch ild safety seat . It
can be a very dangerous place for an infant or a
larger child in a rearward-facing seat.
The vehicle's Advanced Airbag System has a ca­ pacit ive 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 chi ld restra int, and a baby b lanket
are on the front passenger seat. The change in
the measured capacitance due to the presence of
a chi ld, a child restraint, and a baby blanket on
the front passenger seat is related to the child
restraint system resting on the seat. The meas­
ured capacitance of a child restraint system var­
i es depending on the type of system and specific
make and model.
The electrical capacitance of the various types, makes, and models of child restraints specified
by the U.S. National Highway Traffic 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 ch ild. When a
child restraint is used on the front passenger
seat with a typical 1 year-old infant, the Ad­
vanced Airbag System compares the capacitance
measured by the capacitive passenger detection
system with the data stored in the e lectronic con­
tro l unit .

-Do not use run-flat tires on your vehicle. Using them when
not permitted can lead to ve­
hicle damage or accidents.
-If you install wheel covers on
the vehicle, make sure they al­ low enough air circulation to
cool the brake system. If they
do not, this could increase the risk of an accident.
Tire wear/damage
Fig. 276 T ire profile : treadwear indica­
tor
Tire wear
Check the tires regular ly for wear.
-Inflation pressure that is too low or high can increase tire wear
considerably.
-Driving quickly through curves,
rapid acceleration and heavy
braking increase tire wear.
l ) Obey any applicable regulations in your
country.
Wheels
-Have an authorized Audi dealer or authorized Audi Service Facili­
ty check the wheel alignment if
there is unusual wear.
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear more quickly.
Treadwear indicator
Original equipment tires contain
treadwear indicators in the tread
pattern, which are bars that are 1/16 in (1.6 mm) high and are
spaced evenly around the tire per­ pendicular to the running direc­
tion
c::> fig. 2 76. The letters "TWI"
or triangles on the tire sidewall indicate the location of the tread­
wear indicators.
The tires have reached the mini ­
mum tread depth

A 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 authorized Audi Service Facility.
- For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regulations, see
r=;,page 386.
