What impairs driving safety?
Safe driving is dire ctly related to the condition of
the vehicle, the driver as well as the driver's abili
ty to concentrate on the road without being dis
tracted.
T he dr iver is responsib le for the sa fe ty of the ve
hicle and a ll of its occupants. If your ability to
drive is impai red, safety risks for everybody in the
vehicl e inc rease and you a lso become a hazard to
everyone else on the road
¢ A_ . Therefore:
.. Do not let yourse lf be distracted by passenge r
or by using a ce llular telephone .
.. NEVER drive when your driving ability is im
pa ired (by med ications, alcohol, drugs, etc.) .
.. Observe all traffic laws, rules of the road and
speed lim its and plain common sense .
.. ALWAYS adjust your speed to road, traffic and
weather conditions .

for more than two hours at a stretch.
,.. Do NOT drive when you are tired, under pres
sure or when you are stressed.
A WARNING
Impaired driving safety increases the risk of
serious personal injury and death whenever a
vehicle is being used.

For your own safety and to reduce the risk of in
jury in the event of an accident, we recommend
that you adjust the driver's seat to the following
position :
,.. Adjust the driver's seat so that you can easily
push the pedals all the way to the floor wh ile
k eeping your knee(s) s lightly bent
c:> .&_ .
,.. Adjust the angle of the seatback so that it is in
an upright position so that your back comes in
full contact with it when you drive.
,.. Adjust the steering wheel so that there is a dis
tance of at least 10 in (25 cm) between the
steering wheel and your breast bone
c:> fig. 150.
If not possible, see your authorized Audi deal
ersh ip about adaptive equipment .
,.. Adjust the steering wheel so that the steering
whee l and airbag cover points at you r chest and
not at your face.
180
,.. Grasp the top of the steering wheel with your
elbow(s) slightly bent.
,.. Fasten and wear safety belts correctly
c:> page 190 .
,.. Always keep both feet in the footwell so that
you are in control of the vehicle at all times .
For detailed information on how to adjust the
driver's seat, see
c:> page 46, Front seats.
A WARNING
Drivers who are unbelted, out of position or
too close to the airbag can be seriously in -
ju red by an airbag as it unfolds. To help re-
duce the risk of serious pe rsonal injury:
-Always adjust the driver's seat and the
steer ing wheel so that the re are at least
10 in (25 cm) between your breastbone and
the steering wheel.
-Always adjust the driver's seat and the
steer ing whee l so that there are at least 4 in
(10 cm) between the knees and the lower
pa rt of the instrument pane l.
- Always hold the steering wheel on the out
side of the steering wheel rim with your
hands at the 9 o'clock and 3 o'clock posi
tions to help reduce the risk of personal in
jury if the dr iver's a irbag inflates.
- Never hold the steering wheel at the
12 o'clock position or with your hands at
other positions inside the steering whee l
rim or on the steering wheel hub . Holding
the steering wheel the wrong way can cause
serious injuries to the hands, arms and head
if the driver's airbag inflates
- Pointing the steering wheel toward your face decreases the ability of the supplemen
tal driver's airbag to protect you in a coll i
sion.
- Always sit in an upright pos it ion and never
lean against or place any part of your body
too close to the area where the airbags are
located.
- Before driving, always adjust the front seats
properly and make sure that all passengers

Airbag system
The PASSENGER AIR BAG OFF~; light in the
headliner tells you when the front Advanced Air
bag on the passenger side has been turned off by
the electronic control unit.
E ach time you turn on the ignition, the
PASSEN
GER AIR BAG OFF
"1; ON@ light will come on
for a few seconds and:
- PASSENGER AIR BAG OFF ~; will come on if
the front passenger seat is not occupied,
-PASSENGER AIR BAG OFF ~; will come on if
t h e e lectrica l capacitance measured by the ca
pacitive passenger detection system for the
front passenger seat equa ls the combined ca
pacitance of an infant up to about one year of
age and one of the rearward-facing or forward
facing child restraints listed in Federal Motor
Vehicle Safety Standard 208 w ith which the Ad
vanced Airbag System in your vehicle was certi
fied. For a listing of the ch ild restraints that
were used to cert ify your vehicle 's compliance
with the U.S. Safety Standard
¢page 218.
- PASSENGER AIR BAG OFF~; will come on if
there is a small child or ch ild rest raint on the
front passenger seat,
-PASSENGER AIR BAG ON @w ill go off if the
front passenger seat is occupied by an adult as
registered by the capacitive passenger detec
tion system ¢
page 205, Monitoring the Ad
vanced Airbag System .
The PASSENGER AIR BAG OFF~; light comes on
when electrical capacitance registered on t he
front passenger seat is equa l to or less than the
combined capacitance of a typica l 1 year -o ld in
fant and one of the rearward-facing or forward
facing ch ild restraints listed in Federal Motor Ve
h icle Safety Standard 208 with wh ich the Ad
vanced A irbag System in your vehicle was cert i
f ie d.
If the tota l electrical capac itance registered on
the front passenger seat is more than that of a
typical 1 year-old child but less than the we ight
of a small adult, the front a irbag on the passen
ge r side ca n deploy (the
PASSENGER AIR BAG
OFF
"1; light does not come on).
If the
PASSENGER AIR BAG OFF "1; light does
not come on, the front a irbag on the passenger
196
side has not been turned off by the electronic
contro l unit and can deploy if the contro l unit
senses an impact that meets the conditions stor
ed in its memory.
For example , the airbag may deploy
if:
-a small c hild that is heav ier than a typica l 1
year-old child is on the front passenger seat
(regard less of whethe r the child is in one of the
child sa fety seats listed ¢
page 218), or
- a child who has outgrown child restraints is on
the front passenger seat.
If the front passenger a irbag is turned off, the
PASSENGER AIR BAG OFF~; light comes on in
the headliner and stays on.
If the front passenger airbag deploys, the Feder
al Standard requires the airbag to meet the "low
r isk" dep loyment cr iteria to reduce the r isk of in
jury through interaction w ith the airbag. "Low
risk" deployment occurs in those crashes that
take place at lower decelerations as defined in
the e lectronic contro l unit ¢
page 206, PASSEN
GER AIR BAG
OFF~; ON~ light.
A lways remember, a child seat or infant carrier
installed on the front seat may be struck and
knocked out of position by the rapidly inflating
passenger's airbag in a frontal col lision. The air
bag could great ly reduce the effectiveness of the
c hi ld restraint and even ser iously injure the child
during inflat io n.
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 inflat ing 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.
- Forward-facing child seats installed on the
front passenger's seat may interfere with
the deployment of the airbag and cause se
r ious personal injury to the ch ild.

A WARNING
If, in exceptional circumstances, you must in
stall a forward-facing child restraint on the
front passenger's seat:
- Always make sure the forward-fac ing seat
has been designed and certified by its man
ufacturer for use on a front seat with a pas
senger front and s ide a irbag.
- Never put the forward-facing child restraint
up against or ve ry near the instrument pan

- Always move the front passenger seat to
the highest position in the up and down ad
justment range and move it back to the
re ar most position in the se at's fore and aft
adjustment range, as fa r away from the air
bag as possib le, before insta lling the for
ward-facing child restraint .
-Always make sure that the safety belt upper
anchorage is behind the child restraint and
not next to or in front of the chi ld restraint
so that the safety belt will be properly pos i

A WARNING
--
If, in exceptional c ircumstances, you must in
stall a forward or rearward-facing child re
stra int on the fron t passenger 's seat :
- Imp roper installat ion of child restraints can
reduce the ir effectiveness or even prevent
them from providing any pro tect ion .
- An improperly installed child restra int can
interfere wi th the airbag as it deploys and
serio usly injure or even kil l the chi ld -even
wit h an Advanced A irbag System.
- Always carefully follow the manufacturer's
instr uctions provided with the child seat or

that requires the front airbag to be turned
off . If
the
PASSENGER AIR BAG OFF '1; light does not
come on, the front airbag on the passenger side has not been turned
off by the control unit and
can deploy if the control unit senses an impact
that meets the conditions stored in its memory .
If the tota l electrical capac itance registered on
the front passenger seat is more than that of a
typical 1 year -old, but less than the weight of a
small adult , the front airbag on the passenger
side may deploy (the
PASSENGER AIR BAG OFF

Advanced Airbag System components
The front passenger seat in you r vehicle has a lot
of very impo rtant parts of the Advanced Airbag
Sys tem in it. These pa rts in cl ude the capaci tive
passenger detection system, w iring, brac kets,
and more. The control unit monitors the system
on the front passenger seat when the ignition is
switched on and turns the airbag indicator light
on when a malfunct ion in the one of the system
components is detected
¢ page 206. Because
the front passenger seat contains important
pa rts of the Advanced Airbag System, you must
take ca re to prevent it from be ing damaged .
D amage to the seat may p reve nt the Advanced
A irbag System fo r the fron t passenger seat from
doi ng its job in a crash.
The front Advanced Airbag System consists
of the following :
-Cr ash sensors in the front of the vehicle t hat
measure vehicle accelerat ion/dece lerat ion to
Airbag syste m
prov ide information to the Advanced A irbag
System about the severity of the cras h.
- An electronic contro l uni t, with integrated
cras h sensors for front and side impacts . The
control unit "decides" whether to fire the front
airbags based on the information rece ived from
the crash sensors . The control unit also "de
cides" whether the safety belt pretensioners
should be activated.
- An Advanced A irbag w it h gas generator for the
driver inside the steering wheel hub .
- An Advanced A irbag w ith gas generator inside
the instrument panel for the front passenger.
- A capacit ive passenger detection system under
neat h the front passenger seat cover. This sys
tem meas ures the e lectr ica l capacitance of the
