least 10 inches (25 cm) between the steering wheel and
your breast bone=:> fig. 118. 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 that the upper edge is as even with the top of your head as possible but no lower
than eye level and so that it is as close to the back of your
head as possible =:> fig . 119 .

& WARNING
Drivers who are unbelted, out of position or too close to the airbag
can be seriously injured by an airbag as it deploys. 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
125 cm) between your breastbone and
the steering wheel. ..

Driving Safely -
----------------
& WARNING (continued)
• Always adjust the driver's seat and the steering wheel so that
there are at least 4 inches (10 cm) between the knees and the
lower part of the instrument panel.
• 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 inflates
• Pointing the steering wheel toward your face decreases the
ability of the supplemental driver's airbag to protect you in a colli­
sion .
• Always sit in an upright position 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 and head
restraints properly and make sure that all passengers are properly
restrained .
• Never adjust the seats while the vehicle is moving. Your seat
may move unexpectedly and you could lose control of the vehicle.
• Never drive with the backrest reclined or tilted far back! The
farther the backrests are tilted back, the greater the risk of injury due to incorrect positioning of the safety belt and improper
seating position.
• Children must always ride in child seats=>

Vehicle care Do-it-yourself service Technical data

Because the occupants in th is vehicle are not using safety belts
~ page 138, fig. 122, they will keep moving at the same speed the
vehicle was moving just before the crash, un til some thing stops
them -here, the wall ~ page 138 , fig . 123.
The same principles apply to people sitting in a vehicle that is involved in a frontal collision. Even at city speeds of 20 to 30 mph
(30 to 50 km/h) , the forces acting on the body can reach one ton
(2,000 lbs, or 1,000 kg) or more . At higher speeds , th ese forces are
even greater.
People who do not use safety bel ts are also not attached to their
vehicle. In a frontal collision they will also keep moving forward at
the speed their vehicle was travelling just before the crash . Of
course, the laws of physics don't just apply to frontal collisions, they
determine what happens in all kinds of accidents and collisions. •
What happens to occupants not wearing
safety belts?
In crashes unbelted occupants cannot stop themselves
from flying forward and being injured or killed. Always
wear your safety belts!

wearing a safety belt is

Unbelted occupants are not able to resist the tremendous forces of
impact by holding tight or bracing themselves . Without the benefit
of safety restraint systems, the unrestrained occupant will slam

Safety belts
violently into the steering wheel, instrument panel, windshield, or
whatever else is in the way ~ fig. 124 . This impact with the vehicle
interior has all the energy they had just before the crash.
Never rely on airbags alone for protection. Even when they deploy,
airbags provide only additional protection. Airbags are not
supposed to deploy in all kinds o f accidents. Although your Audi is
equipped with airbags, all vehicle occupants, including the driver,
must wear safety belts correctly in order to minimi ze the risk of
severe injury or death in a crash.
Remember too , that airbags will deploy only once and that your
safety belts are always there to offer protection in those accidents
in which airbags are not supposed to deploy or when they have
already deployed. Unbelted occupants can also be thrown out of the
vehicle where even more severe or fatal injuries can occur. •
Safety belts protect
People think it's possible to use the hands to brace the
body in a minor collision. It's simply not true!

erly restrained in a
sudden braking
maneuver .
Safety belts used properly can make a big difference. Safety belts
help to keep passengers in their seats, gradually reduce energy
levels applied to the body in an accident, and help prevent the
uncontrolled movement that can cause serious injuries. In addition ,
safety belts reduce the danger of being thrown out of the vehicle. .,.

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 safe ty a nd the safety of your passengers, before
driving o ff, a lways:
- Adjust the driver's seat and steering wheel properly
~ page 130,
-Adjust the front passenger's seat properly~ page 88,
- Wear safety belts properly~ page 140,
-Always properly use the proper child restraint to pro tect
children~
page 168 .
In a collision airbags must inflate within the blink of an eye and with
considerable force. The supplemental airbags can cause 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 important, both as
a driver and as a passenger to sit properly at a ll times.
By keep ing room between your body and the steering wheel and the
front of the passenger compartment, the airbag can inflate fu lly and
comp letely and prov ide supplementa l protection in certain frontal
collisions =>
page 130, "Proper occupant seating positions". For
detai ls on the operation of the seat adjustment controls =>
page 88
and=> page 89.
It's especially important that chi ldren are proper ly restrained
=>
page 168.
There is a lot that the dr iver and the passenger can and must do to
help the individual safety features installed in your Audi work
together as a system.
P roper seating position is important so that the front airbag on the
driver side can do its job. I f 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, o r if
you have concerns with regard to the function or operation of the
Advanced Airbag System, p lease contact your authorized Audi
dea ler or qua lif ied workshop, or call Audi Customer CARE at 1-800-
822 -2834 for possib le 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 be tween the instrument panel
and the front passenger. The airbags wil l deflate immediate ly after
deployment so that the front occupants can see through the wind ­
shield again without interruption.
A ll of this takes p lace in the b link 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 dep loy. Fron t airbags in combination wi th properly worn
safety belts slow down and limit the occupant's forward movement.
T ogether they he lp to prevent the driver and passenger from hitting
parts of the inside the vehic le while reducing the forces acting on
the occupant during the crash. In this way they he lp to reduce the
r isk 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 inflate in al l fro ntal col lisions . The trig­
gering of the airbag system depends on the vehic le deceleration
r ate caused by the colli sion and registe red by the electronic contro l
unit. If this rate is below the reference value programmed into the
cont rol unit, the airbags w ill not be t riggered, even though the car
may be bad ly damaged as a result of the collision. Vehicle damage, .,,,.

________________________________________________ A_ i_ r _b _a_, g:::.,_ s..., y'- s_ t_ e_ m ___ !II
repair costs or even the lack of vehicle damage is not necessari ly an
indication of whether an airbag should inflate or not.
It is not possible to define a range of vehicle speeds that will cover
every possible kind and ang le of impact that wil l always trigger the
airbags, since the circumstances wil l vary considerab ly between
one collision and another. Important factors include, for example,
the nature (hard or so ft) of the object which the car hits, the angle
of impact, vehicle speed, etc. The front airbags wi ll also not inflate
in side or rear co llisions, or in roll -overs .
Al way s rem ember : Airbags wi ll deploy only once, and on ly in certain
kinds of coll isions . Your safety belts are always there to offer protec­
tion in those situat ions in wh ich airbags are not supposed to deploy,
or when they have already deployed; for example, when your vehic le
strikes or is struck by another a fter the first coll ision.
T his is just one of the reasons why an airbag is a supplementary
restraint and is not a substitute for a sa fety be lt. The airbag system
works most effectively when used with the safety be lts. Therefore ,
a lways prope rly wea r your safety belt s =>

& WARNING
Sitting too clo se to the steering wheel or in strument panel will
de crease the effect ivene ss of the airbags and will incr ease the risk
of personal injury in a collision.
• Never sit closer than 10 in ches (25 cm) to the steering wheel or
