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

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 . •

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. ..,

- Then press the rollover bar all the way down until you
hear it engage.
Check to make sure the rollover bar is securely engaged
before you release your grip on the bar.
Close the cover @~ page

- Perform the same procedure on the second rollover bar.
- You can now open and close the power top again.
& WARNING
• If there is a problem in the rollover protection system, the
system must be checked by a professional mechanic as soon as
possible.
If this is not done, there is a risk that the rollover protec­
tion system may not be activated in the event of an accident.
• No modifications of rollover protection system components
are permitted.
• Work on the rollover protection system must only be done by a
professional mechanic . Improperly performed work can cause the
system to fail or release unintentionally, possibly causing an
injury!
• Always have your vehicle serviced whenever the service
interval display indicates that it is time for service . This will ensure
that the system will operate properly over the long term. The roll­ over protection system must be checked by a professional
mechanic every two years or sooner. •
