& 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

Proper seating position for the front
passenger
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 =>
page 151.
-Keep both feet flat on the floor in front of the front
passenger seat.
- Fasten and wear safety belts correctly=>
page 163.
For detailed information on how to adjust the front passenger's
seat, see => page 92.

& WARNING (continued)
• Passengers must always sit in an upright position and never
lean against or place any part of their body too close to the area
where the airbags are located.
• Passengers who are unbelted, out of position or too close to the
airbag can be seriously injured by an airbag as it unfolds with
great force in the blink of an eye.
• Always make sure that there are at least 10 inches (25 cm)
between the front passenger's breastbone and the instrument
panel.
• Always make sure that there are at least 4 inches (10 cm)
between the front passenger's knees and the lower part of the
instrument panel.
• Each passenger must always sit on a seat of their own and
properly fasten and wear the safety belt belonging to that seat.
• Before driving, always adjust the front passenger seat and
head restraint properly.
• Always keep your feet on the floor in front of the seat. Never
rest them on the seat, instrument panel, out of the window, etc .
The airbag system and safety belt will not be able to protect you properly and can even increase the risk of injury in a crash.
• 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~
page 190. Special
precautions apply when installing a child seat on the front
passenger seat~
page 168. •
Proper seating positions for passengers in
rear seats
Rear seat passengers must sit upright with both feet on
the floor consistent with their physical size and be prop­
erly restrained whenever the vehicle is in use.
To reduce the risk of injury caused by an incorrect seating
position in the event of a sudden braking maneuver or an
accident, your passengers on the rear bench seat must
always observe the follow ing :
- Make sure that the seatback of the front seats are securely latched in the upright position~
page 99.
Keep both feet flat in the footwell in front of the rear seat .
Fasten and wear safety belts properly ~
page 163.
-Make sure that children are always properly restrained in
a child restraint that is appropriate for their size and age
~ page 190.
& WARNING
Passengers who are improperly seated on the rear seat can be
seriously injured in a crash.
• Each passenger must always sit on a seat of their own and
properly fasten and wear the safety belt belonging to that seat.
• Safety belts only offer maximum protection when the seatback
is securely latched in the upright position and the safety belts are
properly positioned on the body . By not sitting upright, a rear seat
passenger increases the risk of personal injury from improperly
positioned safety belts! •

Driving Safely ---------------=------=~
Proper adjustment of head restraints
Correctly adjusted head restraints are an important part
of your vehicle's occupant restraint system and can help
to reduce the risk of injuries in accident situations.
Fig . 156 Correctly
adjusted head restraint
viewed from the side
The head restraints must be correctly adjusted to achieve
the best protection.
- Adjust the head restraint so that the upper edge of the
restraint is level with the top of your head, but no lower
than eye level and so it is as close to the back of your
head as possible
=> fig . 156.
Adjusting head restraints=> page 95 and=> page 98.
The head restraints on the rear seats are fixed and cannot be
adjusted =>
page 101.
& WARNING
Driving without head restraints or with improperly adjusted head
restraints increases the risk of serious injuries in a collision . To
help reduce the risk of injury:
• Always drive with the head restraints in place and properly
adjusted .
Controls and equip­ ment Safety first Vehicle operation
& WARNING
(continued)
• Every person in the vehicle must have a properly adjusted head
restraint.
• Always make sure each person in the vehicle properly adjusts
their head restraint. Each head restraint must be adjusted
according to occupants' size so that the upper edge is as even
with the top of the person's head, but no lower than eye level and
so it is as close to the back of to the head as possible .
• Never attempt to adjust head restraint while driving. If you
have driven off and must adjust the driver headrest for any reason,
first stop the vehicle safely before attempting to adjust the head
restraint .
• Children must always be properly restrained in a child restraint
that is appropriate for their age and size=>
page 190.
[ i] Tips
In the event of a rear collision, the shape of the seat specifically
supports the upper part of the body and the head is supported at an
early stage. This increases the protective action and decreases the
risk of whiplash. •
Examples of improper seating positions
The occupant restraint system can only reduce the risk of
injury if vehicle occupants ore properly seated.
Improper seating positions can cause serious injury or
death. Safety belts can only work when they are properly
positioned on the body. Improper seating positions reduce
the effectiveness of safety belts and will even increase the risk of injury and death by moving the safety belt to critical
areas of the body. Improper seating positions also increase
the risk of serious injury and death when an airbag deploys ..,

• two solid rollover bars
• the safety bel ts with belt tensioners
• the windshield frame
• the ro llover sensor system. The automatic rol
lover protection system provides additional
protection in case the vehicle ro lls over. As the vehicle starts to tilt,
the sensors activate the two rollover bars located behind the rear
seats to shoot up wi thin a fraction of a second~ fig. 158 .
In combinat ion with the reinforced windshield frame and the bel t
tensioners, the rollover p rotection bars help to protect the passen ­
gers in the front and in the rear in case of a rollover.
The automatic rollover protection system activates with the power
top open
and closed.

When is the rollover protection system
triggered?
T he rollover protection system is triggered in a collisi on or
if the vehicle overturns in an accident.
The electronic control unit processes the signals from the on -board
sensors, evaluates vehicle motion and forces act ing on the vehic le.
Depending on the severity of the co llision, the control unit then acti ­
vates the rol lover protection system .
If the vehicle rol ls sideways beyond a certain angle , the first action
is to extend the ro llover bars . If the vehicle rolls further, the system
wil l additional ly activate the front belt tensioners and, if there are
passengers on the rear seats and they are wearing the safety belts,
the rear belt tensioners as well. ..,

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 vehicle has a total of four seating positions : two in the front
and two in the rear. Each seating posi tion 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 ~
Your vehicle has a warning system to remind you about
the importance of buckling-up.
Before driving off, always:

The warning light~ in the instrument cluster lights up when the
ignition is switched on as a reminder to fasten the safety belts. In
addition, you will hear a warning sound.
After the ignition is switched on, the warning tone will come on for about 6 seconds a long w ith a-~ warning light in the instru ment
cluster if the driver has not fastened his safety belt . As soon as the
driver has fastened his safety belt, the warning tone will stop and
the warning light will go out .
I f the driver has not buckled -up within about 24 seconds after the
warn ing tone has stopped, the warn ing tone will sound again for
about 6 seconds. The warning tone will sound repeated ly for about
6 seconds at 24 second intervals unti l the driver has buckled-up . The
safety belt warning system is active for about 5 minutes and during
this time the wa rning light in the instrument c luster will stay on.

also properl y put on the ir saf ety belts. •
Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create ve ry strong forces for pe ople ri ding
in vehicles.
Fig . 16 2 Unbel ted
occ upants in a ve hicle
h ead in g fo r a wall
F ig . 16 3 T he vehi cle
c ras he s in to t he wa ll
The physica l principles are simple. Both the vehicle and the passen­
gers possess energy which varies with vehicle speed and body
we ight . Engineers call this energy "kinetic energy ."
The higher the speed of the vehicle and the greater the vehicle's
we ight, the mo re energy that has to be "absorbed" in the crash .
Vehicle speed is the most significant factor. If the speed doub les
from 15 to 30 mph (25 to 50 km/h), the energy increases 4 times!
~

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

Safety belts
Fig. 165 A rear

a safety belt will fly

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. •

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!

Safety belts used properly can make a big difference . Safety belts
help to keep passengers in their seats, gradually reduce energy levels app lied to the body in an accident, and help prevent the
uncontrolled movement that can cause serious injuries . In addition,
safety be lts reduce the danger of being thrown out of the vehic le.
Safety belts attach passengers to the car and give them the benefit
of being s lowed down more gently or "sof tly" through the "give" in
the safety belts, crush zones and other safety features engineered
into today's vehicles. By "absorbing" the kinetic energy
over a
longer period of time, the safety belts make the forces on the body
more "tolerable" and less likely to cause injury.
Although these examples are based on a frontal co llision, safety
belts can a lso substantially reduce the risk of injury in other kinds
of crashes. So, whether you're on a long tr ip or just going to t he
corner store, always buckle up and make sure others do, too. Acci ­
dent statistics show that vehic le occupants properly wearing safety
belts have a lower risk of being injured and a much better chance of
s u rviv ing an acc ident. Proper ly using safety belts also great ly
increases the abi lity of the supplementa l airbags to do their job in a
coll ision. For this reason, wearing a safety be lt is legally required in
most countries including much of the United States and Canada . Although your Audi is equipped with airbags, you sti
ll have to wear
t he safety belts provid ed. Fron t airbags, for example, are activated
only in some frontal collisions. The front airbags are not activated in
a ll frontal co llisions, in side and rear collisions, in ro ll
ove rs or in
cases where there is not enough dece leration through impact to the
front of the vehicle. The same goes for the other ai rbag systems in
your Audi. So, a lways wear your safety belt and make sure
eve ry­
body in your vehic le is properly restrained! •
