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
Controls and equip­
ment Safety first Vehicle operation
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.I.
- 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. •

Airbag system
Important things to know
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints. For airbags to
do their job, occupants must always properly wear their
safety belts and be in a proper seating position.
For your safety and the safety of your passengers, before
driving off, a lways:
- Adjust the driver's seat and steering wheel properly
=>
page 148,
- Adjust the front passenger's seat properly => page 93,
- Wear safety belts properly=> page 162,
- Always properly use the proper child restraint to protect
children=>
page 190 .
In a collision airbags must inflate within the blink of an eye and with
considerable force . Th e suppl emental airbags can caus e injuries if
the driver or the front seat passenger are not seated proper ly . There ­
fore in order to help the airbag to do its job, it is impor tant, both as
a driver and as a passenger to sit properly at all times.
By keeping room between your body and the steering wheel and the
front of the passenger compartment, the airbag can inflate fully and
completely and prov ide supplementa l protection in certain frontal
collisions ~
page 148, "Proper occupant seating positions" . For
details on the operation of the seat adjustment controls~
page 93
and ~ page 96.
It's especially important that chi ldren are proper ly restrained
~ page 190.
There is a lot that the driver and the passengers can and must do to
help the individual safety features installed in your Audi work
together as a system.
Proper seating posi tion is important so that the front airbag on the
driver side can do its job. If you have a physical impairment or
condition that prevents you from sitting properly on the driver seat
with the safety belt properly fastened and reaching the pedals, or if
you have concerns with regard to the function or operation of the
Advanced Airbag System, please contact your authorized Audi
dea ler or qua lif ied workshop, or call Audi Customer CARE at 1-800 -
822 -2834 for possible modifications to your vehicle .
When the airbag system deploys, a gas generator wi ll fill the
airbags, break open the padded covers, and inflate between the
steering wheel and the driver and between the instrument panel
and the front passenger. The airbags will deflate immediately after
deployment so that the front occupants can see through the wind ­
shield again without interruption .
All of this takes p lace in the blink of an eye, so fast that many people
don't even rea lize that the airbags have dep loyed. The airbags also
inflate with a great deal of force and nothing should be in their way
when they deploy . Front airbags in combination with properly worn
safety bel ts slow down and limit the occupant's forward movement.
Together they help to prevent the driver and front seat passenger
from hitting parts of the inside the vehicle while reducing the forces acting on the occupant during the crash . In this way they help to
reduce the risk of injury to the head and upper body in the crash .
Airbags do not protect the arms or the lower parts of the body.
Both front airbags w ill not in flate in al l frontal collisions . The trig ­
gering of the airbag system depends on the vehic le deceleration
rate caused by the collision and registered by the electronic contro l
unit. If this rate is below the reference value programmed into the
control unit, the airbags will not be triggered, even though the car
may be badly damaged as a result of the collision . Vehicle damage, .,

• Ther efore , always wear your safety belt s and ma ke sure that
eve rybod y in your vehi cle is prope rly re str ained.
& WARNING
A person on the front p assenger se at, espe cially infant s and small
c hildren , will re ceive seriou s injuries and can ev en be killed by
being t oo clos e to the airbag when it infl ates.
• Although the Adva nced Airbag System in your ve hicle i s
de signed to turn off the front passenger airb ag i f a n infant or a
s mall child i s on the front pa ssenger seat , nobody can absolutely
gu ara ntee that deployment under these spe cial co nditio ns is
impos sible in all conceivable situations that m ay happen during
the useful life of your vehicle.
• The Adv an ced Airbag Sy stem can deploy in a ccordance with
the "lo w risk" option unde r the U .S. Feder al Stand ard if a child t hat
is heavier than the typi cal on e-year old child i s on th e front
pa sse nger seat an d the other condition s for airb ag dep loym ent

• Acc ident stat istics have sh own that children are gen erally s afer

• For th eir own safet y, all children , espe cially 12 yea rs and

their age and size. •
Advanced front airbag system
Your vehicle is equipped with a front Advanced Airbag System in
compliance with United States Federal Motor Vehicle Sa fety Stan ­
dard 208 as applicable at the time your vehicle was manufactured.
Controls and equip­
ment Safety first Vehicle operation
The front Advanced Airbag System supplements the safety belts to
provide additional protection for the driver's and front passenger's
heads and upper bodies in frontal crashes. The airbags inflate only
in frontal impacts when the vehic le deceleration is high enough.
The front Advanced Airbag System for the front seat occupants is not a substitute for your safety belts . Rather, it is part of the overall
occupant restraint system in your vehicle. A lways remember that
the airbag system can only help to protect you, if you are sitting
upright, wear ing your safety be lt and wear ing it proper ly . This is why
you and your passengers must a lways be properly restrained, not
just because the law requires you to be .
The Advanced A irbag System in your veh ic le has been certified to
meet the "low risk" requirements for 3 and 6 year -o ld children on the
passenger side and very small adults on the driver side. The low risk
deployment criteria are intended to he lp reduce the risk of injury
through interact ion with the front 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
"suppression" requirements of the Safety Standard, to turn off the
front airbag for infants 12 months old and younger who are restrained on the front passenger seat in child restraints that are
listed in the Standard~
page 192, "Child restraints and Advanced
Airbags".
"S uppression" requi res the front ai rbag on the passenger side to be
turned off if:
• a child up to about one year of age is restrained on the front
passenger seat in one of the rear-facing or forward-facing infant
restraints listed in Federal Motor Vehicle Safety Standard 208 with
wh ich the Advanced Airbag System in your vehicle was certified. For
a listing of the child restraints that were used to certify your
vehic le's compliance wi th the US Safety Standard ~

• weight less than a threshold leve l stored in the control unit is
