What impairs driving safety?
Safe driving is directly related to the condition of the
vehicle, the driver as well as the driver's ability to concen­
trate on the road without being distracted .
The driver is responsible for the safety of the vehicle 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::::,,& . There­
fore:
Do not let yourself be distracted by passengers or by using
a cellular telephone.
NEVER drive when your driving ability is impaired (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 pressure or when
you are stressed .
& WARNING
Impaired driving safety increases the risk of serious personal
injury and death whenever a vehicle is being used.•

Proper occupant seating positions
Proper seating position for the driver
The proper driver seating position is important for safe,
relaxed driving.
Fig. 122 Correct
seating position
For your own safety and to reduce the risk of injury 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~& .
- Adjust the angle of the seatback so that it is in an upright
pos ition so that your back comes in full contact with it
when you drive.
- Adjust the steering wheel so that there is a distance of at least 10 inches (25 cm) between the steering wheel and
your breast bone~ fig . 122. If not possible, see your
authorized Audi dealership about adaptive equipment.
- Adjust the steering wheel so that the steering wheel and airbag cover points at your chest and not at your face. -
Grasp the top of the steering wheel with your elbow(s)
slightly bent.
- Adjust the head restraint so the upper edge is as even as
possible with the top of your head. If that is not possible,
try to adjust the head restraint so that it is as close to this
position as possible.
- Fasten and wear safety belts correctly~
page 139.
-Always keep both feet in the footwell so that you are in
control of the vehicle at all t imes.
F o r deta iled informat ion on how to adjust the d river 's seat, see
=>
page 74 , "Adjusting front seats manually " or => pag e 75,
"Adjus ting the power sea t".
& WARNING
Drivers who are unbelted, out of position or too close to the airbag
can be seriously injured by an airbag as it unfolds. To help reduce
the risk of serious personal injury:
• Always adjust the driver's seat and the steering wheel so that
there are at least 10 inches (25 cm) between your breastbone and
the steering wheel.
• Always hold the steering wheel on the outside of the steering
wheel rim with your hands at the 9 o'clock and 3 o'clock positions
to help reduce the risk of personal injury if the driver's airbag
inflates.
• Never hold the steering wheel at the 12 o'clock position or with
your hands at other positions inside the steering wheel 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 deploys.
• Pointing the steering wheel toward your face decreases the
ability of the supplemental driver's airbag to protect you in a colli·
sion. .,

Safety belts
General notes
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety belts are necessary, how
they work and how to adjust and wear them correctly.
- Read all the information that follows and heed all of the
instructions and WARNINGS.
& WARNING
Not wearing safety belts or wearing them improperly increases
the risk of serious personal injury and death.
• Safety belts are the single most effective means available to
reduce the risk of serious injury and death in automobile acci­
dents. For your protection and that of your passengers, always
correctly wear safety belts when the vehicle is moving.
• Pregnant women, injured, or physically impaired persons must
also use safety belts. Like all vehicle occupants, they are more
likely to be seriously injured if they do not wear safety belts. The
best way to protect a fetus is to protect the mother - throughout
the entire pregnancy. •
Number of seats
Your Audi has a total of five seating positions: two in the front and
three in the rear . Each seating position has a safety belt .
Controls and equip­
ment Safety first Vehicle operation
& WARNING
Not wearing
safety belts or wearing them improperly increases
the risk of serious personal injury and death.
• Never strap more than one person, including small children,
into any belt. It is especially dangerous to place a safety belt over
a child sitting on your lap.
• Never let more people ride in the vehicle than there are safety
belts available.
• Be sure everyone riding in the vehicle is properly restrained
with a separate safety belt or child restraint. •
Safety belt warning light t
Your vehicle has a warning system for the driver and front
seat passenger ( on USA models only) to remind you about
the importance of buckling-up.

Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very stron g forc es for people
riding i n vehi cles.

cr as hes int o t he w all
T he p hys ica l pr inc iples are simple. Both the vehicle and the passen­
gers possess energy which var ies wit h veh icle speed and body weight.
Enginee rs ca ll t his ene rgy "kinetic energy."
The higher the speed of the veh icle and the greater the vehicle's
we ight, the more energy that has to be "absorbed" in the crash .
Vehicle speed is the most sig nifican t fa ctor. If t he speed doubles
from 15 to 30 mph (25 to 50 km/h), the energy increases 4 times! .,

you hear it latch secure ly==> fig. 131 .
- Pull on the be lt to make sure tha t it is secure ly la tched in
the buck le.
Automatic safety belt retractors
Every safety be lt is equipped with an automatic be lt retractor on the
shoulder be lt. This feat ure locks the be lt whe n the belt is pulled out
fast, during hard braking and in an acc ident. The belt may also lock
w hen you dr ive up or dow n a steep hill or throug h a sharp curve.
Dur ing normal driv ing the belt lets you move freely.
Safety belt pretensioners
The safety belts are equipped w ith a belt pretensioner that helps to
t ighten the safety be lt and remove sla ck when the p re tensioner is
act ivated. The function of the pretensioner is monitored by a warn ing
light =>
page 15.
Switchable locking feature
Every sa fety be lt ex ce pt t he one on the driver sea t is eq uipped wi th a
switchab le locking feature that
must be used when the safety belt is
used to at tach a child safety seat. Be s ure to read t he importa nt info r­
mation about this feature=>
page 177.
& WARNING
Imp roperly positioned safety belts can c au se se rious injury in a n
accident =>
page 140, "Safety b elt po sition ".
• Safety belts offer optimum protection only when the seatback
i s upr ight and belts are properly positioned on the body .
• Always make sure th at the rear seat backre st to which the
center rear safety belt is attached i s secur ely latched when ever the
rear cente r sa fety belt is be ing u sed . If the ba ckre st is not securely
latched, the pas senger will move forward with th e backre st during
sudde n braking, in a sudden maneuve r and especiall y in a crash .
& WARNING (continued )
• Never attach the safety belt to the buckle fo r another seat .
Attaching the belt to the wrong buckle will reduce safety belt
effectiveness and can cause ser ious personal injury.
• A pass enger who i s not properly restrained can be seriou sly
i njured by the safety belt itself when it mo ves from the stronger
part s of the body into critical area s like the abdomen.

Child restraints on the front seat - some
important things to know
- Be su re to re ad t he i mpo rt a nt i nfo rmation a nd head the
WA RNINGS fo r i mporta nt details about chil dre n and
Advanced Airbags ~
page 167.
Even t hough your ve hicle is eq uipped with an Advanced Airbag
System, ma ke ce rtain that a ll chi ld ren, especia lly those 12 years an d
younger, always r ide in the back seat prope rly rest rained fo r th eir age
and si ze. The airbag on the passenger side makes the front seat a
po tentially da ngerous place fo r a child to r ide. The fro nt seat is not
the safest place for a ch ild in a forward-facing child safety seat. It can
be a very dange rous place fo r an i nfan t or a child in a rearward-fac ing
seat.
Th e Advanced Ai rbag System in your vehicle has been cer tified to
comply with the req uirements of Un ited States Federa l Moto r Veh icle
Sa fety Standard 208 as applicable at the time your vehicle was manu­
factured.
The Standard requires the front airbag on the passenger side to be
tu rne d off ("s uppressed") if a c hild up to abou t one ye ar of age
restra ined in o ne of the rear -facing or forward -fac ing infant
restra ints listed in Federa l Moto r Vehicle Safety Standard 208 with
whic h the Advanced Airbag System in yo ur vehicle was cert ified has
been installed on the front passenger seat. For a listing of the ch ild
restra in ts that were used to certify compliance with the US Saf ety
Standard =>

T he
PASSENGER AIR BAG OFF light comes o n when t he control unit
de tects a total weight on t he front passenger seat that req uires the
front airbag to be t urned off .
If th e total weight o n the front passenger seat is more than th at of a
typical 1 year-o ld child but less than the weight of a small adult, the

light does not come on, the front airbag on the passenger side has
not been turned off by the electronic co ntrol unit and can deploy if
the control unit senses an impact t hat meets the conditions stored in
its memory.
For example, the airbag may deploy if:
• a small child that is heavier than a typical 1 year -old child is on the
front passenger seat (regard less of whether the chi ld is in one of the
child safety seats listed =>
page 169), or
• a child who has outgrown child restraints is on the front passenger
sea t.
If the fro nt passenger a irbag is tur ned off, the
