What impairs driving safety?
Safe driving is directly related to the condition of
the vehicle, the driver as well as the driver 's abili­
ty to concentrate on the rood without being dis ­
tracted .
The driver is responsible for the safety of the ve­
hicle and all of its occupants. If your ability to
drive is impaired, safety risks for everybody in the
vehicle increase and you also become a hazard to
everyone else on the road
c:> Li').. Therefore :
• Do not let yourself be distracted by passengers
or by using a cellular telephone .
• NEVER drive when your driving ability is im­
paired (by medications, alcohol, drugs , etc.).
• Observe all traffic laws, rules of the road and
speed limits and plain common sense.
• ALWAYS adjust your speed to road, traffic and
weather conditions.
• Take frequent breaks on long trips. Do not drive
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
ser ious 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 while
keeping your knee(s) slightly 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 d is­
tance of at least 10 inches (25 cm) between the
steering wheel and your breast bone

Airbag syste m
seat. It can be a very dangerous place fo r an
infant or a child in a rearward -facing seat.
The Advanced Airbag System i n your veh icle has
been ce rt ified to comp ly with the requirements
of United States Federa l Motor Vehicle Safety
Standard ( FMVSS)
208, as well as Canada Motor
Veh icle Safety Standard (CMVSS)
208 as applica ­
b le at the time your vehicle was manufactured.
According to requirements, the front Advanced
Airbag System on the passenger s ide has been
certified for "suppression " for infants of about
12 month old and younger and for "low risk de­
p loyment " for children aged
3 to 6 years o ld (as
defined in the standard).
The
PA SSENGER AIR BAG OFF light in the instru­
ment panel tells you when the front Advanced
Ai rbag on the passenger side has been tu rned off
by the ele ct roni c con trol unit.
Each t ime you sw itch on the ign it ion, the
PAS­
SENGER AIR BAG OFF
li ght will come on fo r a
few seconds and:
- will stay on if the front passenger seat is not
occupied,
- will stay on if there is a small c hild or child re­
straint on the front passenger seat,
- will go off if the front passenger seat is occu­
pied by an adult as reg istered by the weight ­
sensing mat¢
page 156, Monitoring the Ad­
vanced Airbag System .
The PASSENGER AIR BAG OFF light comes on
when the control unit detects a tota l we ight on
the front passenger seat that requires the front
a ir bag to be turned off.
If the tota l weight 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 ir bag on the passenger side can deploy (the
PASSENGER AIR BAG OFF ligh t does not come
on) .
If the PASSENGER AIR BAG OFF light does
not come on, the front a irbag on the passenger
side has not been turned
off by the electronic
control unit and can deploy if the control unit
senses an impact that meets the condit ions stor ­
ed in its memory.
For e xample, the airbag may deploy if:
148
- a small ch ild that is heav ier than a typica l 1
year-o ld child is on the front passenger seat
(regard less of whether the child is in one of the
child seats listed ¢
page 170), or
- a child who has outgrown c hild restraints is on
the front passenger seat.
If the front passenger a irbag is t urned
off, the
PASSENGER AIR BAG OFF light comes on in the
i nstrument cluster and stays on.
The fro nt airbag on the passenge r side m ay
not
deploy (the PASSENGER AIR BAG OFF light does
not ill uminate and stay lit) even if a small adu lt
or teenager, or a passenger who is not sitting up­
right with their back against a non-recl ined back­
rest with the ir fee t on the vehicle floor in front of
the sea t is on the front passenger seat
<=> page 130, Proper seating position for the driv ­
er .
If the front passenger a irbag deploys, the Feder­
al Standard requires the airbag to meet the "low
risk" deployment cr iteria to reduce the r isk of in ­
j ury th rough interaction w ith the airbag . "low
risk" deployment occurs in th ose crashes that
take place at lowe r decele rations as defi ned in
the e lec tronic co ntro l unit
¢ page 156, PASSEN­
GER AIR BAG O FF light.
Always remembe r, a ch ild seat or i nfant ca rr ie r
i nsta lled on the fron t seat may be s truck a nd
k nocked o ut of pos it ion by the rapid ly inflat ing
passenger 's airbag in a frontal co llision . The air­
bag cou ld great ly reduce the effectiveness of the
c hi ld rest raint and even seriously injure the child
during in flat ion.
Fo r th is reason, and beca use the back seat is the
safest place for children - when proper ly restrain ­
ed according to their age and size -we strongly
recommend that children always sit in the back
seat
c> page 168, Child safety .
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
Sys tem.

-The inflating 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 .
- Always install rear-facing child seats on the
rear seat.
- If you must install a rearward facing child
seat on the front passenger seat because of
exceptional circumstances and the
PASSEN­
GER AIR BAG OFF
light does not come on
and stay on, immediately install the rear­
facing child seat in a rear seating position
and have the airbag system inspected by
your Audi dealer.
- Forward-facing child seats installed on the
front passenger's seat may interfere with
the deployment of the airbag and cause se­ rious personal injury to the child.
,&. 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 -facing seat
has been designed and certified by its man­
ufacturer for use on a front seat with a pas­
senger front and side airbag.
- Never put the forward-facing child restraint
up against or very near the instrument pan­
el.
-Always move the passenger seat into its
rearmost position in the seat's fore and aft
adjustment range, as far away from the air ­
bag as possible before installing the for­
ward-facing child restraint. The backrest must be adjusted to an upright position.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the time
whenever the ignition is switched on.

straint on the front passenger's seat:
- Improper installation of child restraints can
reduce their effectiveness or even prevent
them from providing any protection.
-An improperly installed child restraint can
interfere with the airbag as it deploys and
seriously injure or even kill the child -even
with an Advanced Airbag System.
- Always carefully follow the manufacturer's
instructions provided with the child seat or
carrier.
- Never place additional items on the seat
that can increase the total weight registered
by the weight-sensing mat and can cause in­
jury in a crash.

Airbag syste m
-a small adu lt or teenager is on the front pas ­
senger seat
- a passenger who is not sitting upright with
their back against a non -reclined backrest with
their feet on the vehicle floor in front of the
seat is on the front passenger seat.
I f the front passenger airbag dep loys, the Feder ­
al Standard requires the airbag to meet the "low
risk" deployment criteria to help reduce the risk
of injury through interaction with the airbag.
"Low risk" deployment occurs in those crashes
that take place at lower decelerations as def ined
in the electronic control unit¢
page 156.
Alway s remember: Even though your vehicle is
equ ipped w ith Advanced Airbags, the safest place
for children is properly restrained on the back
seat . Please be sure to read the important infor­
mat ion in the sections that follow and be sure to
heed a ll of the WARN INGS.
A WARNING
To red uce the risk of inj ury when an ai rbag in­
fla tes, a lways wear safety bel ts p roperly.
- If you are unrestrained, leaning fo rwa rd, s it­
t ing s ideways or o ut of pos ition in any way,
yo ur risk of in jury is much h igher .
- Yo u will also re ceive serious injur ies and
could even be killed if you are up aga inst the
airbag or too close to it when it inflates -
even with an Advanced Airbag ¢
page 146.
A WARNING
A child in a rearward-facing chi ld seat insta l­
led on the front passenger seat will be seri­
ously injured and can be k illed if the front air­
bag inflates -even with an Advanced Airbag
System.
- Although the Advanced A irbag System in
your vehicle is designed to turn off the front
airbag when a rearward-facing child re­
straint has been installed on the front pas­
senger seat, nobody can absolutely g uaran­
tee that deployment is impossible in all con­
ceivable s ituations that may happen during
the usef ul life of your vehicle .
- The inflating a irbag w il l hit the child seat or
infant carrier w ith great force and will
152
-
smash the child seat and child against the backrest, center armrest, door, or roof.
- Always install rearward-facing child re ­
straints on the rear seat.
- If you must install a rearward facing child
seat on the front passenge r seat because of
except ional circumstances and the
PASSEN­
GER AIR BAG OFF
light does not come on
and stay on, immed iate ly install the rear­
facing chi ld seat in a rear seating posit ion
and have the airbag system inspected by
your Aud i dea le r.
A WARNING
If, in exceptional ci rcums tances, you must in­

Advanced Airbag System components
The front passenger seat in your veh icle has a lot
of very important parts of the Advanced A irbag
System i n it. These parts incl ude t he weight­
sens ing mat, senso rs, wir ing, bracke ts, and
more. The funct ion of the sys tem in the front
passenger seat is checked by the electronic con ­
tro l unit when the ignition is on . The control unit
monitors the Advanced Airbag System and turns
the airbag ind icator light on when a malfunction
i n the system components is detected. The func­
tion of the ai rbag ind icator light is described in
greater deta il be low. Because the front .,.

passenger seat contains important parts of the
Advanced Airbag System, you must take care to prevent it from being damaged . Damage to the
seat may prevent the Advanced A irbag for the
front passenger seat from doing its job in a
crash.
The f ront Ad vanced Airb ag Sy stem con sist s
of the follo wing :
-Crash sensors in the front of the vehicle that
measure vehicle accelerat ion/decelerat io n to
provide information to the Advanced Airbag
System about the severity of the crash .
- An electronic control un it, with integrated
crash sensors for front and side impacts . The
contro l unit "decides" whethe r to fire the front
airbags based on the information received from
the crash sensors. The control unit also "de ­
cides" whether the safety be lt pretensioners
sho uld be activated.
- An Advanced Airbag with gas generator and
contro l valve for the driver inside the steering
whee l hub .
- An Advanced Airbag with gas generator and
contro l valve inside the instrument pane l for
the front passenger.
- A weight -sensing mat under t he upho lstery
padding of the front passenger seat cushion
that measures the total weight on the seat . The
information registered is sent continuously to
the e lectron ic control unit to regulate deploy­
ment of the front Adva need A irbag on the pas ­
senger side.
- An airbag monitoring system and indicator
light i n the instrument cluster
¢ page 156.
-A sensor in each front seat registers the dis­
tance between the respective seat and the
steering wheel or instrument panel. The infor­
mation reg istered is sent cont inuous ly to the
electronic control unit to regulate deployment
of the fro nt Adv a need A irbags.
- T he
PASS EN GE R AIR BAG OFF light comes on
and stays on in the center of the instrument
pane l
¢page 156, fig . 166 and tells you when
the fron t Advanced Airbag on the passenge r
side has been turned off.
- A se nsor below the safety bel t lat ch fo r th e
front seat passenger to meas ure the tens ion on
Airb ag sys tem
the sa fety belt. The tension on the safety belt
and the weight registered by the weight-sens­
ing mat help the contro l unit "decide" whether
the front airbag for the front passenger seat should be turned off or not¢
page 147, Child
restraints
on the front seat -some important
things to know.
- A sensor in the safety belt latch for the driver
and for the front seat passenger that senses
whether that safety belt is latched o r not and
t ransmits this information to t he electronic
cont rol un it.
_& WARNING
D amage to the front passenge r seat can pre­
vent the front airbag from working properly.
- Imp roper repair or disassembly of the fro nt
passenger and driver seat will p revent the
Advanced Airbag System from f unctioning
p roperly.
- Repairs to the front passenger seat must be
performed by qualified and p roperly trained
workshop personne l.
- Never remove the front passenge r or driver
seat from the vehicle.
- Never remove the upholstery from the front
passenger seat.
- Never disassemble o r remove par ts from the
seat o r disconnect w ires from it.
- Never carry sh arp objects in your pocke ts or
p lace them on the seat. If the weight-sens­
ing mat in the passenger seat is punctu red
it cannot work proper ly.
- Never carry things on your lap or carry ob­
jects on the passenge r seat. S uch items can
increase the weight reg istered by the
weight-sensing mat and send the wrong in­
formation to the a irbag control unit.
- Never store items under the front passenger
seat. Parts of the Advanced Airbag System
under the passenger seat could be dam­
aged, p reventing them and the airbag sys­
tem from working p roper ly.
- Never p lace seat covers or replacement up­

How the Advanced Airbag System
components work together
The front Advanced Airbag System and the side
ai rbags supplement the protection offered by the
front three-point safety belts with pretensioners and load limiters and the adjustable head re ­
stra ints to help reduce the r isk of injury in a wide
range of accident and crash situations. Be sure to
read the important information about safety and heed the WARNINGS in th is chapter .
Deployment of the Advanced Airbag System and
the activation of the safety belt pretensioners de­ pend on the deceleration measured by the crash
sensors and registered by the electronic control
unit . Crash severity depends on speed and decel­
era tion as we ll as the mass and stiffness of the
vehicle or object invo lved in the crash.
On the passenger s ide, regardless of safety belt
use, the a irbag will be t urned off if the weight on
the passenge r seat is less than the amount p ro­
g rammed in the e lectron ic cont rol unit . T he front
154
airbag on the passenger side will also be turned
off if one of the chi ld seats that has been certi­
fied under Federal Motor Vehicle Safety Standard 208 has been recognized on the seat. The
PA S­
S EN GER AIR BA G OFF
light comes on and stays
on to tell you when the front Advanced A irbag on
the passenger side has been turned off
