& WARNING
• Unintended vehicle movement can cause serious injury .
- When the selector lever is in a driving position , the vehicle
may creep , even at idle speed . Therefore do not release the
parking brake or foot brake until you are ready to move,
because power is transmitted to the wheels as soon as a
driving position is engaged.
- Do not accelerate while selecting a driving position . At this
time the engine must be at idle speed so that undue stress is
not placed on the clutches in the transmission .
- Remember: -even when stopped briefly with the automatic
transmission in "D ", "S " or "R ", engine power is being trans­
mitted to the wheels. Your vehicle could "creep" forward or
ba ckward . When stopped , keep the brake pedal fully depressed
and use the parking brake if necessary to keep the vehicle from
rolling .
• If the selector lever is unintentionally moved into N while you
are driving , take your foot off the accelerator pedal and wait for
the engine to return to idle speed before selecting a driving posi ­
tion .
• Never shift into "R " or "P " when the vehicle is in motion .
• Never get out of the driver 's seat when the engine is running .
• If you must get out of the vehicle , move the selector lever
securely into the P pos ition and apply the parking brake firmly .
• If the engine must remain running , never have any dr iving posi ­
tion engaged when checking under the hood . Make sure the

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
position 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. 154. 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. 155.
- Fasten and wear safety belts correctly=:>
page 163.
- Always keep both feet in the footwell so that you are in
control of the vehicle at all times.

=> page 93 and :::::, page 96 .
& 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. ...

& WARNING (continued)
• Always adjust the driver's seat and the steering wheel so that
there are at least 4 inches 110 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

The proper front passenger seating position is important
for safe, relaxed driving.
For your own safety and to reduce the risk of injury in the
event of an accident, we recommend that you adjust the
seat for the front passenger to the following pos ition:
- Move the front passenger seat back as far as possible.
There must be a minimum of 10 inches (25 cm) between
the breastbone and the instrument panel =>
&.
- Adjust the angle of the seatback so that it is in an upright
position and your back comes in full contact with it
whenever the vehicle is moving.
- Adjust the head restraint so that the upper edge is as
even with the top of your head as possible but not lower
than eye level and so that it is as close to the back of your
head as possible =>

Vehicle care Do-it-yourself service Technical data

Because the passengers of this vehicle are not using safety belts
~ page 160, fig. 162, they will keep moving at the same speed the
vehicle was moving just before the crash, until something stops
them -here, the wall
~ page 160, fig. 163.
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 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
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!
Safety first
Fig . 164 A driver not
wearing a safety belt is

Safety belts
Fig. 165 A rear

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. 164 . 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. 165. 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, 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, .,

__________________________________________________ A_ i_ r _b _a...; g::- s_ y=--- s_t _e _m ___ lJII
repair costs or even the lack of vehicle damage is not necessarily 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 angle of impact that will always trigger the
airbags, since the circumstances will vary considerably between
one collision and another. Important factors include, for example,
the nature (hard or soft) of the object which the car hits, the angle of impac t, vehicle sp eed , etc . The front airbags will also not inflate
in side or rear collisions, or in roll-overs.
Always remember : Airbags will deploy only once, and only in certain
kinds of collisions. Your safety belts are always there to offer protec­
tion in those situations in which airbags are not supposed to deploy,
or when they have already deployed; for example, when your vehicle
strikes or is struck by another after the first collision.
This is just one of the reasons why an airbag is a suppl em entary
restraint and is not a substitute for a safety belt. The airbag system
works most effectively when used with the safety belts. Therefore ,
always properly wear your safety belts=>
page 159.
& 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 held 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.
Controls and equip­ ment Safety first
Vehicle operation
& WARNING (continued)
• To reduce the risk of injury when an airbag inflates, always
wear safety belts properly~
page 163, "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 inflates.
• 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 148, "Proper occupant seating posi­
tions".
• 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 serious 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 necessary tools and
diagnostic equipment to properly replace any airbag in your
vehicle and assure system effectiveness in a crash.
• Never permit salvaged or recycled airbags to be installed in
your vehicle. •
