- For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechnic circuit interrupter .
- Work on the pyrotechnic circ uit inter rupt­
er must only be performed by a qualified
technicians w ho have the experience, in­
formation and special tools necessary to perform the work safely.
- If the veh icle or the circuit interrupter is
scrapped, a ll applicable safety precautions
must be followed.
@ For the sake of the environment
Undep loyed airbag modu les and pretension ­

straint system including a irbag modules and
safety belts with prete nsioners are scrapped ,
all applicable laws and regulat ions must be
observed. Your authorized A udi dealer is fa­
m iliar with the se requirements a nd we recom­
mend that you have your dealer perform this
service for yo u.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system ca n
change the way that the Advanced A irbag System
performs in a crash. For example, using t ire- rim
combinat ions not approved by Audi, lower ing the
ve hicl e, chang ing the stiffness of the suspension,
includ ing the spr ings, suspension s truts, shoc k
absorbers etc. can change the forces that are
measured by the a irbag sensors and sent to the
e lectronic control unit. Some suspension changes
can, for example, increase the force levels meas ­
ured by the sensors and make the a irbag system
deploy in c rashes in which it wou ld not deploy if
the changes had not been made. Other ki nds of
changes may reduce the force levels measured by
164
the sensors and p revent the airbag from dep loy ­
ing when it shou ld .
A 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
ter istics as the components origina lly instal­
led on you r vehicle.
- Never use tire-rim combinations that have
not been approved by Audi.
Knee airbags
Description of knee airbag s
Applies to vehicles: with knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front seat
occupants .
Fig. 132 Driver 's knee a irbag
The driver knee airbag is i n the instrument panel
u nderneath the steer ing wheel ~
fig. 132 , the
airbag fo r the passenger is at abou t the same
height in the i nstr ument panel underneath the
glove comp artment.
The knee airbag offers additional protection to
the d river's and passenge r's kn ees and uppe r and
lower thigh areas and supplements the protec­
tion provided by the safety belts.
If the front a irbags deploy, the knee a irbags also
deploy in fronta l co llisions when the dep loyment

Child safety
Advanced front airbag system and children
Your vehicle is equipped with a front "Advanced
Airbag System" in compliance with United States Federal Motor Vehicle Safety Standard (FMVSS)
208 as applicable at the time your vehicle was
manufactured.
The Advanced Airbag system in your vehicle 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
"suppression " requirements of the Safety Stand­
ard, to turn off the front airbag for infants up to
12 months who are restrained on the front pas­
senger seat in child restraints that are listed in
the Standard.
Even though your vehicle is equipped with an Ad­
vanced Airbag system, all children, especially
those 12 years and younger, should always ride 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 to ride. The front seat is not the safest place
for a child in a forward-facing child 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
pacitive passenger detection system in the front
passenger seat cushion that can detect the pres­
ence of a baby or a child 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 blanket
are on the front passenger seat. The change in
the measured capacitance due to the presence of
a child, a child restraint, and a baby blanket on
the front passenger seat is related to the child re­
straint system resting on the seat. The measured
capacitance of a child restraint system varies de-
174 pending
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
typical of infants and a 1-year old child. When a
child restraint is used on the front passenger seat
with a typical 1 year-old infant, the Advanced Air­
bag System compares the capacitance measured
by the capacitive passenger detection system
with the data stored in the electronic control
unit.
Child restraints and Advanced front airbag
system
Regardless of the child 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 airbag. Always be sure that the child
restraint is properly installed at one of the rear
seating positions. If in exceptional circumstances
you must use it on the front passenger seat, care­
fully read all of the information on child safety
and Advanced Airbags and heed all of the appli­ cable WARNINGS. Make certain that the child
and child restraint are correctly recognized by the
capacitive passenger detection system in the
front passenger seat, that the front passenger airbag is turned off, and that the airbag status is
always correctly signaled by the
PASSENGER AIR
BAG OFF
light .
Many types and models of child restraints have
been available over the years, new models are in­
troduced regularly incorporating new and im­
proved designs and older models are taken out of
production. Child restraints are not standardized.
Child restraints of the same type typically have
different weights and sizes and different "foot­
prints", the size and shape of the bottom of the
child restraint that sits on the seat, when they
are installed on a vehicle seat . These differences
make it virtually impossible to certify compliance
with the requirements for advanced airbags with ..,.

load limits.
-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
trol.

A WARNING
-
-You or your passengers could be injured
wh ile chang ing a wheel if you do not follow
these safety precautions:
- Position the vehicle jack only at the desig­
nated lifting points and align the jack.
Otherwise, the vehicle jack could slip and
cause an injury if it does not have suff i­
cient hold on the vehicle.
-A soft or unstable surface under the jack may cause the vehicle to slip off the jack.
Always provide a firm base for the jack on
the ground. If necessa ry, use a sturdy
board under the jack.
- On ha rd, slippery surface (such as tiles)
use a rubber mat o r similar to prevent the
jack from slipping .
- On ly raise your vehicle with the vehicle
jack provided by the factory . If you use a
vehicle jack for another vehicle, your vehi­
cle can slide and cause injury.
- Changes in temperature or load can affec t
the height o f the vehicle .
- Never start the engine when the vehicle is
raised, which could cause an accident.
- Support the vehicle securely with appro­
priate stands if work is to be performed
underneath the vehicle; otherwise, there
is a potentia l risk for injury .
244
-To help prevent injury to yourself and your
passengers :
- Do not ra ise the vehicle until you are su re
the jack is securely engaged.
- Passengers must not remain in the veh icle
when it is jacked up.
- Make sure that passengers wait in a safe place away from the veh icle and we ll away
from the road and traffic.
- Make sure jack position is correct, adjust
as necessary and then continue to raise
the jack.
- Changes in temperature or load can affect
the height of the vehicle.
