• 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

& 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! •

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 ..,

Important safety instructions
& WARNING
Always make sure that the knee airbag can inflate without inter­
ference. Objects between yourself and the airbag can increase the risk of injury in an accident by interfering with the way the airbag
deploys or by being pushed into you as the airbag deploys.
• No persons (children) or animals should ride in the footwell in
front of the passenger seat.
If the airbag deploys, this can result in
serious or fatal injuries .
• No objects of any kind should be carried in the footwell area in
front of the driver's or passenger's seat. Bulky objects (shopping
bags, for example) can hamper or prevent proper deployment of
the airbag. Small objects can be thrown through the vehicle if the
airbag deploys and injure you or your passengers. •
Pedal area
Pedals
The pedals must always be free to move and must never
be interfered with by a floor mat or any other object.
Make sure that all pedals move freely without interference and that
nothing prevents them from returning to their original positions.
~

________________________________________________ D_r_iv _ i _n_, g,::._ S_ a_ fe__, ly'-------.J"'
Only use floor mats that leave the pedal area free and can be
secured with floor mat fasteners.
If a brake circuit fails, increased brake pedal travel is required to
bring the vehicle to a full stop.
& WARNING
Pedals that cannot move freely can cause loss of vehicle control
and increase the risk of serious injury.
• Never place any objects in the driver's footwell. An object could
get into the pedal area and interfere with pedal function . In case
of sudden braking or an accident, you would not be able to brake
or accelerate!
• Always make sure that nothing can fall or move into the
driver's footwell. •
Floor mats on the driver side
Always use floor mats that can be securely attached to
the floor mat fasteners and do not interfere with the free
movement of the pedals.
-Make sure that the floor mats are properly secured and
cannot move and interfere with the pedals~&.
Use only floor mats that leave the pedal area unobstructed and that
are firmly secured so that they cannot slip out of position. You can
obtain suitable floor mats from your authorized Audi Dealer.
Floor mat fasteners are installed in your Audi.
Floor mats used in your vehicle must be attached to these fasteners.
Properly securing the floor mats will prevent them from sliding into
positions that could interfere with the pedals or impair safe opera ­
tion of your vehicle in other ways .
Controls and equip­
ment Safety first Vehicle operation
& WARNING
Pedals that cannot move freely can result in a loss of vehicle
control and increase the risk of serious personal injury.
•
Always make sure that floor mats are properly secured .
• Never place or install floor mats or other floor coverings in the
vehicle that cannot be properly secured in place to prevent them
from slipping and interfering with the pedals or the ability to control the vehicle.
• Never place or install floor mats or other floor coverings on top
of already installed floor mats. Additional floor mats and other
coverings will reduce the size of the pedal area and interfere with
the pedals.
• Always properly reinstall and secure floor mats that have been
taken out for cleaning .
• Always make sure that objects cannot fall into the driver foot­
well while the vehicle is moving. Objects can become trapped
under the brake pedal and accelerator pedal causing a loss of
vehicle control . •
Stowing luggage
Loading the luggage compartment
All luggage and other objects must be properly stowed
and secured in the luggage compartment.
Loose items in the luggage compartment can shift
suddenly, changing vehicle handling characteristics. Loose
items can also increase the risk of serious personal injury in
a sudden vehicle maneuver or in a collision.
- Distribute the load evenly in the luggage compartment . ..,

The automatic rollover protection system cons ists of these compo ­
nents:
• 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. ..,

To provide extra safety, the rollover protection system is also acti­
vated in head -on, side and rear -end collisions if the impact is severe
enough. •
Lowering the rollover protection bars after
deployment
Lower the rollover protection bars only if the bars were
automatically deployed without the vehicle actually
colliding or overturning.
