What impairs driving safety?
Safe driving is directly related to the condition of the
vehicle, the driver as well as the driver's ability to concen­
trate on the road without being distracted.
The driver is responsible for the safety of the vehicle and all
of its occupants. If your ability to drive is impaired, safety
risks for everybody in the vehicle increase and you also

ment Safety first Vehicle operation
become a
hazard to everyone else on the road ~& .There ­
fore:
- Do not let yourself be distracted by passengers or by
using a cellular telephone.
- NEVER drive when your driving ability is impaired (by
medications, alcohol, drugs, etc.I.
- Observe all traffic laws, rules of the road and speed limits
and plain common sense.
- ALWAYS adjust your speed to road, traffic and weather
conditions.
- Take frequent breaks on long trips. Do not drive for more
than two hours at a stretch.
- Do NOT drive when you are tired, under pressure or when
you are stressed.
& WARNING
Impaired driving safety increases the risk of serious personal
injury and death whenever a vehicle is being used. •

& 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
=> page 190. Special
precautions apply when installing a child seat on the front
passenger seat

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.

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 ..,

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 .
