Luggage compartment
lid
General information

— After closing the luggage compartment lid,
make sure that it is latched. The luggage
compartment lid could open suddenly while
driving, which would increase the risk of an
accident.
— Never drive with the luggage compartment
lid ajar or open, because poisonous gases
from the surrounding area can enter the ve-
hicle interior and increase the risk of asphyx-
iation.
— If there is a luggage rack (such as a bicycle
rack) on the luggage compartment lid, the
luggage compartment lid may not open
completely under certain circumstances or it
could close by itself if open due to the extra
weight. Therefore, the open luggage com-
partment lid must be given additional sup-
port or the cargo must first be removed
from the luggage rack.
— Applies to vehicles with power-operated or
sensor-controlled luggage compartment lid:
Pay careful attention when closing the lug-
gage compartment lid. Otherwise, you could
cause serious injury to yourself or others de-
spite the pinch protection.

ZX WARNING
— Applies to vehicles with anti-theft alarm sys-
tem: When the vehicle is locked from the
outside, no one - especially children - should
remain in the vehicle, because the windows
can no longer open from the inside
= page 44. Locked doors make it more diffi-
cult for emergency workers to enter the ve-
hicle, which puts lives at risk.
— Always close and lock the luggage compart-
ment lid and the doors when the vehicle is
not in use. Otherwise someone such as a
child could enter the vehicle through the
luggage compartment and become locked
inside it. To reduce the risk of injury, do not
allow children to play in or around the vehi-
cle.
— To reduce the risk of injuries by pinching,
make sure that no one is in the operating
area of the luggage compartment lid, in-
cluding the hinge areas and the upper and

lower edge of the luggage compartment lid.

seating position
(eT reeeleur isola)
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 70
— The steering wheel is adjusted correctly
=> page 77
— The mirrors are adjusted so that there is a suffi-
cient view of the area around the vehicle

tant safety information pertaining to the use of
child safety seats on the front passenger's seat
= A in General information on page 89.
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. Audi would
simply like to increase your awareness of the top-
ic. The following points apply when the vehicle is
in motion:
— Never stand inside the vehicle.
— Never stand on the seats.
70
— 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.
G) Tips
— Save your seat profile* > page 83. This al-
lows you to access your personal seat profile
quickly and easily at any time.
— If you or other vehicle passengers have
physical limitations that prevent sitting in a
correct position, modifications to the vehi-
cle may be necessary. For more information,

vehicle interior during sudden driving or
braking maneuvers, which increases the risk
of an accident. Store objects securely while
driving.
— Applies to: vehicles with front center arm-
rest The center armrest must remain closed
while driving. Otherwise, the protective
function of the front center airbag could be
impaired because it deploys from the driv-
er's seat backrest. This increases the risk of
injury.



Rear seats
ZA\ WARNING
— The power seats can also be adjusted when
the ignition is switched off. To reduce the
risk of injury, children should never be left
unattended in the vehicle for this reason.
— Be careful when adjusting the seat. Unsu-
pervised or careless seat adjustment could
cause parts of the body to get pinched,
which increases the risk of injury.

ZA\ WARNING
—To reduce the risk of an accident, make sure
the steering wheel is adjusted correctly and
cannot be moved out of position before you
start to drive.
— If you are too close to the steering wheel,
the driver's airbag cannot provide optimal
protection, which increases the risk of injury
or fatality.
— Never hold the steering wheel in the 12:00
position or in any other way, such as holding
the center of the steering wheel. Otherwise,
your arms, hands, and head could be injured
in the event that the driver's airbag deploys.

Head restraints
General information
Applies to: vehicles with adjustable head restraints

B4G-0454


Fig. 64 Correctly-adjusted head restraint
Make sure that:
— The upper edge of the head restraint is as even
as possible with the top of your head
— The head restraint is as close as possible to the
back of the head
— The head restraints on the occupied rear seats
are positioned all the way up or folded upward.

Z\ WARNING
— There is one head restraint for each seat. All
vehicle occupants must adjust the head re-
straint correctly before every trip. Having
head restraints that are not adjusted cor-
rectly or not installed in the vehicle increas-
es the risk of a neck injury during sudden or
unexpected driving or braking maneuvers or
in a collision.
— Only remove the rear seat head restraints if
it is necessary to install a child safety seat
= page 88. Stow the removed head re-
straints securely, for example in the luggage
compartment. Reinstall the head restraints
immediately once the child safety seat has
been removed. Driving without head re-
straints increases the risk of serious neck in-
juries.
— Depending on the equipment, the front
head restraints may be active head re-
straints. If triggered, a part of the head re-
straint will move several inches forward to
provide additional support to the head. If

triggered, have the head restraints serviced

> Press the button @) and slide the head restraint
all the way down. It should not be possible to
remove the head restraint from the backrest
without pressing the button.
Safety belts
(eT eeeleurisela)
Each seat is equipped with a three-point safety
belt. Safety belts that are worn correctly are the
most effective way to reduce the risk of serious or
fatal injuries in a collision. Therefore, wear your
safety belt correctly and make sure that all vehi-
cle passengers are also wearing their safety belts
correctly when the vehicle is moving.
Even though your vehicle is equipped with an air-
bag system, every vehicle passenger must still al-
ways wear the appropriate safety belt. In addi-
tion to their normal protective function, safety
belts also hold vehicle occupants in the correct
seating position in the event of a collision so that
the airbags can deploy correctly and provide addi-
tional protection. Safety belts provide protection
during collisions when the airbags do not deploy
or if they have already deployed.


ZA\ WARNING
The risk of serious or fatal injury increases if
the safety belt is not fastened, if it is worn in-
correctly, or if it is damaged.


80

— All vehicle occupants, including the driver,
must fasten their safety belts correctly be-
fore every trip and must always keep their
safety belts fastened during the trip, regard-
less of whether the seat is equipped with an
airbag or not. This also applies to children
that are seated in a child safety seat that is
appropriate for their weight and age and
that is secured with a safety belt.
In the event of a collision, vehicle occupants
that are not wearing safety belts could be
propelled through the vehicle interior and
collide with vehicle components, such as the
steering wheel, instrument panel, wind-
shield, or doors. In some situations, vehicle
occupants could also be ejected from the ve-
hicle. Vehicle occupants in the rear seats
who do not wear safety belts not only en-
danger themselves, but also other people in
the vehicle.
Only one person may be fastened with a
safety belt at a time. Never secure more
than one person, including children, with a
single safety belt.
Never allow children or infants to ride on an-
other person's lap and be belted into the
safety belt with them.
Insert the belt buckle only in the belt latch
belonging to the corresponding seat, so that
the protective function is not impaired.
To ensure the maximum protective function
of the safety belts, all vehicle passengers
must sit in the correct seating position
=> page 70.
Check the condition of your vehicle’s safety
belts regularly > page 311. If you find dam-
age to the belt webbing, the belt connec-
tions, the retractor, or the buckle, have the
damaged safety belt replaced by an author-
ized Audi dealer or authorized Audi Service
Facility.
The safety belts must not be removed or
modified in any way. Do not attempt to re-
pair the safety belts yourself.
Safety belts that are strained during an acci-
dent must be replaced by an authorized
Audi dealer or authorized Audi Service Facili-
ty.

Sitting correctly and safely

Correct safety belt positioning

B4H-0751


RAZ-0696


Fastened safety belts only offer optimal protec-
tion during an accident and reduce the risk of se-
rious injury or death when they are positioned
correctly. Furthermore, the correct safety belt
position holds the vehicle occupant in place so
that a deployed airbag can provide maximum
protection. Therefore, always fasten the safety
belt and make sure it is positioned correctly
> fig. 68.
To ensure the safety belt is positioned correctly,
make sure of the following points:
— The lap portion of the safety belt must be locat-
ed across the lap.
—The shoulder portion of the safety belt must
rest over the center of the shoulder.
— The safety belt must always rest flat and se-
curely on the body.
For pregnant women, the safety belt must rest
evenly across the chest and as low and flat as
possible on the lap, so that no pressure is applied
to the lower abdomen. This should be done
throughout the entire pregnancy > fig. 69.


ZA\ WARNING
Incorrect safety belt positioning can cause se-
rious injury in the event of an accident or dur-
ing sudden braking or driving maneuvers.
— Never drive with the backrest reclined ex-
tremely far. The more the backrest is tilted
back, the greater the risk of injury due to the
safety belt being routed incorrectly.
— The safety belt itself or a loose safety belt
can cause serious injuries if it shifts onto
soft areas of the body, such as the stomach.
— The shoulder portion of the safety belt must
lie over the center of the shoulder and
chest, and never under the arm, behind the
back, or across the neck or face.
— The lap portion of the safety belt must lie
across the lap and never over the stomach.
—The safety belt must lie flat and securely on
the upper part of the body and the lap.
— The belt webbing must not be pinched or
twisted, or rub against sharp edges.
— If the safety belt height is set incorrectly
and/or the safety belt is routed incorrectly,
then the safety belt's protective function
will be impaired in the event of an accident.
Make sure the safety belt is at the right
height and is routed correctly for the pas-
senger using it.
— A safety belt that is too loose may lead to in-
juries during an accident, because your body
will move farther forward due to kinetic en-
ergy and will be stopped abruptly by the
belt.
— Heavily bulky, loose clothing (for example, a
coat over a sports jacket) may prevent the
seat and safety belts from functioning cor-
rectly.
— Do not position the safety belt over hard or
breakable objects (such as glasses, pens,
etc.).
—The lap belt portion of the safety belt must
sit as low as possible on the lap of pregnant

women and lie flat under the belly.

@) Note
Make sure that there are no hook-and-loop
fasteners or sharp objects such as zippers or

may need to be activated. Follow the instruc-
tions from the child safety seat manufacturer.
>» When a vehicle passenger has fastened a safety
belt, the belt retractor lock should not be acti-
vated. If the belt retractor lock has been acti-
vated unexpectedly, deactivate it.
Deactivating or activating the belt retractor lock
=> page 91.
Safety belt retractor
The safety belts are equipped with an automatic
belt retractor. This automatic retractor allows the
safety belt to be pulled all the way out when the
belt is pulled slowly. However, the automatic re-
tractor locks during sudden braking maneuvers.
It also locks the belts when accelerating, driving
uphill, and driving around curves.
Belt force limiter
Safety belts with belt force limiters reduce the
force placed on the body by the safety belts dur-
ing a collision.
Safety belt pretensioners
Safety belts may be tightened with reversible
belt tensioners when you start driving and in cer-
tain driving situations. If the safety belt is too
loose, it will be tightened so that the belt will
rest closer to the body.
In some collisions, pyrotechnic belt tensioners
may secure the safety belts so that they cannot
loosen. This reduces forward movement by the
vehicle passengers.

Z\ WARNING
The pyrotechnic system can only provide pro-
tection during one collision. If the pyrotechnic
belt tensioners deploy, the pretensioning sys-
tem must be replaced by an authorized Audi
dealer or authorized Audi Service Facility.

@) Tips
Smoke may be released when pyrotechnic belt
tensioners deploy. This is not a sign of a vehi-
cle fire.
