Correct passenger
seating position
General information
As the driver, you are responsible for making sure
every passenger is sitting correctly in their seat
and maintaining this seating position while driv-
ing. Make sure that:
— Every passenger in the vehicle has adjusted his
or her seat correctly > page 63
— The steering wheel is adjusted correctly
=> page 66
— The mirrors are adjusted so that there is a suffi-
cient view of the area around the vehicle
=>page 55
— Every passenger in the vehicle has his or her
head restraint adjusted correctly > page 67

— The activation status of the front passenger's
airbag is suitable for the passenger in the front
passenger's seat > page 74
— Children are secured in suitable child safety
seats that are secured to appropriate vehicle
seats > page 76. Read and observe the impor-
tant safety information pertaining to the use of
child safety seats on the front passenger's seat
=> A\ in General information on page 76.
Examples of incorrect seating positions
Safety belts can only provide its optimal protec-
tion when they are routed correctly. Incorrect
seating positions significantly reduce the protec-
tive functions of the safety belts and increase the
risk of injury due to incorrect belt routing.
The following list includes examples of seating
positions that could be dangerous for all vehicle
occupants. This is not a complete list. The pur-
pose is to provide examples to increase your
awareness of the topic. The following points ap-
ply when the vehicle is in motion:
— Never stand inside the vehicle.
— Never stand on the seats.
— Never kneel on the seats.
— Never tilt your backrest too far back.
— Never lean against the instrument panel.
— Never lie down on the rear bench seat.
— Never sit only on the front section of the seat.
— Never sit sideways on the seat.
— Never lean against the window.
— Never place your feet out of the window.
— Never place your feet on the instrument panel.
— Never place your feet on the seat cushion.
— Never ride in the footwell.
— Never sit on the armrests.
— Never drive or ride in a seat without fastening
your safety belt.
— Never ride in the luggage compartment.

ZA WARNING
Incorrect seating positions, failure to wear a
safety belt, or being too close to an airbag in-
crease the risk of serious or fatal injury to ve-
hicle occupants, especially if the airbags de-
ploy and come into contact with occupants
who are not seated correctly. Note the impor-
tant information and warnings in the chapters
for the topics given above.
Gi) Tips
If you or other vehicle passengers have physi-
cal limitations that prevent sitting in a correct
position, modifications to the vehicle may be
necessary. For more information, contact an
authorized Audi dealer or authorized Audi
Service Facility, or call Audi customer support
at 1-800-822-2834.


Front seats
General information
Make sure that:
— You can press the pedals down completely
while your legs are slightly bent
— The distance between your upper body and the
steering wheel or instrument panel is at least
10 inches (25 cm)
— The distance between your knees and the in-
strument panel is at least 4 inches (10 cm)

>

Sitting correctly and safely

— Your thighs are lightly supported by the front
surface of the seat
— The backrest is in an upright position and your
back is resting against it
— You have a sufficient view of the area around
the vehicle
— You have a clear view of the instrument cluster,
indicator lights, and the head-up display*

Z\ WARNING
— If you are too close to the steering wheel or
instrument panel, the airbag system cannot
provide the optimal protection, which in-
creases the risk of injury and death.
— To reduce the risk of injury in the event of
sudden braking maneuvers or accidents,
never drive with the backrest reclined very
far. The airbag system and seat belts can on-
ly provide optimal protection when the back-
rest is in an upright position and the driver
is wearing the seat belt correctly. If the
backrest is angled back too far, the safety
belt can shift to soft areas of the body, such
as the stomach, which increases the risk of
injury.
—To reduce the risk of an accident, only adjust
the seats when the vehicle is stationary.
— Be careful when adjusting the seat. Lack of
control or attention when adjusting can re-
sult in injuries due to pinching to vehicle oc-
cupants both in the front seats and rear
seats.
— Never place objects in the driver's footwell.
Objects could shift and enter the area
around the pedals, which could prevent you
from using them. You would then be unable
to use the pedals if sudden driving or brak-
ing maneuvers were needed, which increas-
es the risk of an accident.
— Make sure that the floor mats are always se-
curely attached.
— To reduce the risk of an accident, never place
additional floor mats or other floor covers
over the installed floor mats, because this
reduces the pedal's range of motion and can
impair pedal operation.
—To reduce the risk of injury, never place your
feet on the instrument panel, out of the



64

window, or on the seat surfaces. This also
applies to passengers in the rear seats.
(@) Note
Applies to: vehicles with manually adjustable head re-
straints

To reduce the risk of damage, be very careful
when adjusting the seat to make sure the
head restraints do not come into contact with
the headliner or the sunroof*.

Sitting correctly and safely


of whether the seat is equipped with an air-
bag or not.
— Never place your feet on the instrument
panel, out of the window, or on the seat sur-
faces. To help ensure that the airbag system
can deploy correctly, never bend forward or
lean on the door or the side window. Other-
wise, serious and possibly fatal injuries can
occur if the airbags deploy.
— People, animals, or objects between the
passengers and the airbag system can inter-
fere with the correct deployment of the air-
bag or can be thrown through the vehicle in-
terior, increasing the risk of serious or fatal
injuries. Make sure that nothing is located
between the vehicle occupants and the air-
bag system. Do not secure or transport any
objects within the deployment zone of the
airbag systems, especially on the steering
wheel, on the instrument panel, on the
doors, on the windows, or in the footwell.
— Never put stickers on the airbag system cov-
ers or cover them with any objects.
— Only lightweight clothing should be hung
from the garment hooks in the vehicle. Do
not use clothes hangers to hang clothing.
The pockets of the clothing must not con-
tain any heavy, breakable, or sharp-edged
objects. This could impair the effectiveness
of the side curtain airbags.
— You must not use seat or protective covers
that are not specifically approved for use on
Audi seats with side airbags. Since the side
airbags deploy from the seat backrest, such
covers could impair the protective function
of the side airbags.
— Damage to the original seat covers in the
side airbag deployment area must always be
repaired by an authorized Audi dealer or au-
thorized Audi Service Facility.
— Airbag system components are installed at
various locations in your vehicle. Incorrect
work or repairs on the vehicle could damage
the airbag system components or impair
their functionality. This may prevent the air-
bags from deploying or cause them to de-
ploy incorrectly in the event of an accident,
which increases the risk of serious or fatal

72
injuries. Only have an authorized Audi dealer
or authorized Audi Service Facility make re-
pairs or modifications to a vehicle.
— The airbag system can only provide protec-
tion during one collision. If there is another
collision, the airbag system will not deploy
again. If the airbag system has deployed,
have it replaced immediately by an author-
ized Audi dealer or authorized Audi Service
Facility.
— Fine dust may appear if the airbags deploy.
This is completely normal and does not indi-
cate a fire in the vehicle. The fine dust can ir-
ritate the skin and mucous membranes in
the eyes and can cause difficulty breathing,
particularly for individuals who have or have
had asthma or other health issues that af-
fect breathing. Exit the vehicle or open the
windows or doors to get access to fresh air.
(i) Tips
If you are transporting children in the vehicle,
read the information and follow the safety
precautions > page 76.
Safety systems monitoring
The ka indicator light in the instrument cluster
monitors the safety systems such as the airbags
(including the control modules, sensor, and wir-
ing) and the belt tensioners. It turns on when you
switch the ignition on and turns off after several
seconds.


If the indicator light does not turn on when the
ignition is switched on, does not turn off after
several seconds, or turns on or flashes while driv-
ing, there may be a malfunction in one of the
safety systems. Drive to an authorized Audi deal-
er or authorized Audi Service Facility immediately
to have the malfunction corrected.

ZA WARNING
Have the malfunction in the safety systems in-
spected immediately. Otherwise, there is a
risk that the systems may not activate during
an accident, which increases the risk of seri-
ous or fatal injury.
