ment Safety first
& WARNING
Improper use of steering wheel adjustment and improper seating
position can cause serious personal
injury .
• Adjust the steer ing whe el column only when the vehicle is not
moving to prevent loss of vehicle control.
• Always make sure that the adjustment lever is securely pushed
up so that the position of the steering wheel cannot be changed
unintentionally when the vehicle is moving .
• Adjust the dr iver 's seat or steering wheel so that there is a
m inimum of 10 inches (25 cm) between your breastbone and the
steering wheel=>
page 126, fig. 122. If you cannot maintain this
minimum distance, the airbag system cannot protect you prop­
erly.
• If physical limitations prevent you from sitting 10 inches (25
c m) or more from the steering wheel, check with your authorized
Audi dealer to see if adaptive equipment is available .
• Pointing the steering wheel toward your face decrea ses the
ability of the supplemental driver's a irbag to prote ct you in an
accident. Always make sure that the steer ing wheel is pointed
towards your che st .
• Always hold the steering wheel on the outside of the steering
wheel rim with your hands at the 9 o'clo ck and 3 o'clock position s
to help reduce the risk of personal injury if the driver's airbag
inflates .
• Never hold the steer ing 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 injurie s to the hand s, arms and head if th e

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. .,

Because the passengers of this vehicle are not using safety belts
=> page 136, fig. 126, they will keep moving at the same speed the
vehicle was moving just before the crash, until something stops them
- here, the wall =>
page 136, fig. 127.
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 SO km/h), the forces acting on the body can reach one ton (2,000
lbs. or 1,000 kg) or more. At greater speeds, these forces are even
higher .
People who do not use safety belts 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 deter­
mine 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!
Safety first

wearing a safety belt is

Vehicle OP-eration
Safety belts
Fig. 129 A rear
passenger not wearing
a safety belt will fly
forward and strike the driver
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
violently into the steering wheel, instrument panel, windshield, or
whatever else is in the way=> fig. 128. 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 of accidents. Although your Audi is equipped
with airbags, all vehicle occupants, including the driver, must wear safety belts correctly in order to minimize 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.
It is also important for the rear passengers to wear safety belts
correctly. Unbelted passengers in the rear seats endanger not only
themselves but also the driver and other passengers=> fig . 129. In a
frontal collision they will be thrown forward violently, where they can
hit and injure the driver and/or front seat passenger. •

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, always:
- Adjust the driver's seat and steering wheel properly
=>
page 126,
- Adjust the front passenger's seat properly=> page 74,
-Wear safety belts properly=> page 138,
-Always properly use the proper child restraint to protect
children=>
page 167.
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 is not seated properly. Therefore 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 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 provide supplemental protection in certain frontal
collisions =:,
page 126. For details on the operation of the seat
adjustment controls=>
page 75.
It 's especially important that children are properly restrained
=:,
page 167.
Controls and equip­ ment Safety first Vehicle operation
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 position is important so that the front airbag on the
driver side can do its job. If you have a physical impairment or condi­
tion 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 dealer
or other qualified 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 will 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 windshield again
without interruption.
All of this takes place in the blink of an eye, so fast that many people don't even realize that the airbags have deployed . 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 belts 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 of 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 will not inflate in all frontal collisions . The trig­
gering of the airbag system depends on the vehicle deceleration rate
caused by the collision and registered by the electronic control 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, repair

& WARNING
Sitting too close to the steering wheel or instrument panel will
decrease the effectiveness of the airbags and will increase the risk
of personal injury in a collision.
• Never sit closer than 10 inches (25 cm) to the steering wheel or
instrument panel.
• If you cannot sit more than 10 inches (25 cm) from the
steering wheel, investigate whether adaptive equipment may be
available to help you reach the pedals and increase your seating
distance from the steering wheel.
• If you are unrestrained, leaning forward, sitting sideways or
out of position in any way , your risk of injury is much higher.
• You will also receive serious injuries and could even be killed if
you are up against the airbag or too close to it when it inflates - even with an Advanced Airbag.
& WARNING (co ntinued )
• To reduce the risk of injury when an airbag inflates, always
wear safety belts properly=>
page 139, "Safety belts ".
• Always make certain that children age 12 or younger always
ride in the rear seat. If children are not properly restrained, they
may be severely injured or killed when an airbag infl ates .
• Never let children ride unrestrained or improperly restrained in
the vehicle. Adjust the front seats properly.
• Never ride with the backrest reclined.
• Always sit as far as possible from the steering wheel or the
instrument panel =>
page 126.
• Always sit upright with your back against the backrest of your
seat.
• Never place your feet on the instrument panel or on the seat.
Always keep both feet on the floor in front of the seat to help
prevent seriou s injuries to the legs and hips if the airbag inflates.
• Never recline the front passenger's seat to transport objects .
Items can also move into the area of the side airbag or the front
airbag during braking or in a sudden maneuver. Objects near the
airbags can become projectiles and cause injury when an airbag inflates .
& WARNING
Airbags that have deployed in a crash must be replaced .
• Use only original equipment airbags approved by Audi and
installed by a trained technician who has the neces sary tools and
diagnostic equipment to properly replace any airbag in your
vehicle and assure system effectiveness in a crash.
• Never permit salvaged or recycled a irbags to be installed in
your vehicle. •

• Therefore, always wear your safety belts and make sure that
everybody in your veh icle is properly restrained .
& WARNING
A person on the front passenger seat , especially infants and small
c hildren, will receive seriou s injuries and can even be killed by
being too close to the a irbag when it inflates.
• Although the Advanced Airbag System in your vehicle is
designed to turn off the front passenger a irbag if an infant or a
small child is on the front passenger seat, nobody can absolutely
guarantee that deployment under these special conditions is
impossible in all conceivable situations that may happen during
the useful life of your vehicle.
• The Advanced Airbag System can deploy in a ccordance with the
" low risk" option under the U.S. Federal Standard if a child that is
hea vier than the t ypical one-year old child is on the front
passeng er seat and the other condition s for airbag deployment
are met.
• Accident statistics have shown that children are generally safer
in the rear seat area than in the front seating position .
• For their own safety, all children , especially 12 years and
younger, should always ride in the back properly res trained for
their age and size. •
