Safety belts
General information
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.

Z\ 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.
—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 56.
— Check the condition of your vehicle’s safety
belts regularly > page 269. If you find dam-
age to the belt webbing, the belt connec-
tions, the retractor, or the buckle, have the

61

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.

Fig. 56 Safety belt positioning for pregnant women
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. 55.
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.
62
— 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. 56.

Z\ 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.

4KE012721BE
Sitting correctly and safely


— Do not position the safety belt over hard or
breakable objects (such as glasses, pens,
(Ke),
— 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
rivets on clothing in the area where the safety
belt is worn. Otherwise, the safety belt could
be damaged.

Safety belt monitoring system
B- If the indicator light turns on or flashes, a
safety belt is not fastened or it has been unfas-
tened while the vehicle is in motion. Above cer-
tain speeds, additional warning tones will sound.
Depending on the equipment, the safety belts in
the rear may also be monitored using the follow-
ing indicator lights:
aI - If this indicator light turns on, the safety
belt for the corresponding rear seat is not fas-
tened.
Ba - If this indicator light turns on, the safety
belt for the rear seat has been fastened.

Belt retractor lock
The safety belts on the rear seats and on the
front passenger seat are equipped with a belt re-
tractor lock.
> If you secure a child safety seat with a safety
belt, the belt retractor lock on the safety belt
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 72.
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.

ZX WARNING
The pyrotechnic system can only provide pro-
tection during one collision. If the pyrotechnic
belt tensioners deploy, the pretensioning sys-

64

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.

Airbag system
General information

ZA\ WARNING
— If you have not fastened your safety belt,
you are in an incorrect seating position, or
you are too close to the airbag system, the
airbag system will not be able to protect
you. This increases the risk of serious or fa-
tal
injuries. Make sure that every vehicle
passenger has their safety belt correctly fas-
tened and is sitting in a correct seating posi-
tion = page 56. This is necessary regardless
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
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.

@) Tips
If you are transporting children in the vehicle,
read the information and observe the safety
precautions > page 69.

the front passenger's airbag is activated or de-
activated
- indicator light in the instrument cluster:
this monitors the function of the Advanced Air-
bag System components to ensure they are
functioning correctly
How the components function together
The passenger occupant detection sensor in the
front passenger's seat detects if the front pas-
senger's seat is occupied. The passenger occu-
pant detection sensor measures the electrical ca-
pacity on the front passenger’s seat. The pas-
senger's airbag is activated or deactivated de-
pending on the electrical capacity that is meas-
ured.
The passenger's airbag is activated if:
— The electrical capacity is higher than the
threshold stored in the control module
— The electrical capacity is the same as or greater
than the electrical capacity of a typical adult
The passenger's airbag is deactivated if:
— The electrical capacity is lower than the thresh-
old stored in the control module
— The electrical capacity is the same as or less
than the electrical capacity of a typical one-
year-old child in a child safety seat that has
been used for certification in accordance with
FMVSS 208
If the front passenger's airbag is activated, the
PASSENGER AIR BAG ON @ indicator light
will turn on. If the front passenger's airbag is de-
activated, the PASSENGER AIR BAG OFF #;
indicator light will turn on.
The deployment force of the front airbags adapts
based on whether or not the safety belt is used
and the distance between the seat and the steer-
ing wheel/instrument panel. For example, if a
person is too close to the front airbag, the front
airbag will deploy with less force to help reduce
the risk of injury.

When the ignition is switched on, the system de-
tects whether the front passenger's seat is occu-
pied. PASSENGER AIR BAG OFF #;, ON @
will turn on for several seconds during this proc-
ess. Then it will indicate whether the front pas-
senger's airbag is activated or deactivated.
— PASSENGER AIR BAG OFF %;: the front
passenger's airbag is deactivated and will not
deploy in the event of an accident.
— PASSENGER AIR BAG ON ®:: the front pas-
senger's airbag is activated and could deploy in
the event of an accident.
If a change to the occupancy status of the front
passenger's seat is detected,
PASSENGER AIR BAG OFF #; ON @ will
flash for several seconds and will then display the
status of the front passenger's airbag.
Always make sure the indicator light corresponds
to the occupancy of the front passenger's seat.
— Adults or individuals with a similar stature sit-
ting in the front passenger seat: The front pas-
senger's airbag must be activated.
PASSENGER AIR BAG ON ® must remain

event of a collision if the passenger's airbag
is deactivated. This increases the risk of in-
jury and death. Always make sure that
PASSENGER AIR BAG ON @ remains on
while driving. If
PASSENGER AIR BAG ON @ does not
turn on, make sure the front passenger is
sitting correctly in the seat > page 56 and
that there are no objects covering the front
passenger's seat (such as blankets or pil-
lows). If PASSENGER AIR BAG ON @
still does not turn on, the front passenger's
seat must not be used. Drive to an author-
ized Audi dealer or authorized Audi Service
Facility and have the airbag system inspect-
ed.
—Achild ina child safety seat on the front
passenger's seat - especially in a rear-facing
child safety seat - can receive a severe im-
pact if the front passenger's airbag deploys,
which increases the risk of serious or fatal
injury. Always secure child safety seats on
the rear seats. If special circumstances re-
quire the use of a child safety seat on the
front passenger's seat, always make sure
that PASSENGER AIR BAG OFF 3; re-
mains on while driving. If
PASSENGER AIR BAG OFF #¥; does not
turn on, remove the child safety seat and in-
stall it again according to the child safety
seat manufacturer instructions. If
PASSENGER AIR BAG OFF &%; still does
not turn on, the front passenger's seat must
not be used. Drive to an authorized Audi
dealer or authorized Audi Service Facility
and have the airbag system inspected.
— Fluids, electronic devices, or mechanical
damage on the front passenger's seat may
cause the front passenger seat occupant de-
tection to malfunction. The system may
then incorrectly detect if the front passeng-
er's seat is occupied. As a result, it could de-
ploy the front passenger’s airbag incorrectly
or fail to deploy it, which increases the risk
of serious or fatal injury. Make sure that no
wet objects (such as a wet hand towel) and
no fluids come into contact with the front

passenger's seat cushion. If the front pas-
senger's seat becomes wet, dry it immedi-
ately. Make sure no electronic devices (such
as a laptop or a retrofitted seat heater) are
on the front passenger's seat. Do not trans-
port any objects on or under the front pas-
senger's seat.
— Seat covers or protective covers may prevent
the advanced airbag system from correctly
detecting child safety seats or passengers in
the front passenger's seat. You must not use
seat covers or protective covers on the front
passenger's seat that are not specifically ap-
proved for use on Audi seats with an ad-
vanced airbag system.

Child safety seats

Sitting correctly and safely


with a child safety seat that is appropriate for
their body size, weight, and age.
— Children ages 12 and under must be trans-
ported using the appropriate child safety
seat. Note differences in regulations be-
tween states and countries.
— Child safety seats secured incorrectly in the
vehicle may cause serious or fatal injuries in
the event of an accident. Always secure the
child safety seat according to the manufac-
turer instructions.
— Children or babies must not under any cir-
cumstances be held on the lap of the driver
or other passengers while driving.
— Do not secure more than one child in a child
safety seat.
— Never allow a child to sit in a child safety
seat unsupervised.
— Never allow children to ride unsecured in the
vehicle or to stand or kneel on the seats
while driving. In the event of an accident, a
child could be propelled through the vehicle.
This can cause serious or fatal injuries for
the child and passengers.
- If children use an incorrect seating position
while driving, they have a higher risk of in-
jury during a sudden braking maneuver or
accident. This especially applies to children
in the front passenger's seat or children who
have their head near the side airbag deploy-
ment area, if the airbag system is deployed
during an accident. This incorrect seating
position can cause severe or even fatal inju-
ries.
— Make sure there is enough space in front of
the child in the child safety seat. If necessa-
ry, adjust the angle and position of the seat
in front of the child safety seat.
— The rear side of a forward-facing child safety
seat should be positioned as close as possi-
ble to the backrest on the vehicle seat. If the
head restraints make it difficult to install a
child safety seat, adjust or remove them if
necessary > page 60. Reinstall the head re-
straints immediately once the child safety
seat has been removed.
— Always make sure that the backrest on the
seat where the child safety seat is installed


is securely locked in place and cannot move
forward. Otherwise, the backrest where the
child safety seat is secured could move for-
ward in the event of an accident or other
emergency situation.
— NEVER use a rear-facing child safety seat on
a seat with an ACTIVATED FRONT AIRBAG;
this could cause DEATH or SERIOUS INJU-
RIES to a CHILD.
— Always secure child safety seats on the
rear seats. If exceptional circumstances re-
quire the child safety seat to be placed on
the front passenger's seat, then the front
passenger's airbag must be deactivated.
Always make sure that
PASSENGER AIR BAG OFF %; remains
on while driving. If
PASSENGER AIR BAG OFF %; does not
turn on, remove the child safety seat and
install it again according to the child safe-
ty seat manufacturer instructions. If
PASSENGER AIR BAG OFF 4; still
does not turn on, the front passenger's
seat must not be used. Drive to an author-
ized Audi dealer or authorized Audi Service
Facility and have the airbag system in-
spected.
— If you must use a forward-facing child safety
seat on the front passenger's seat, move the
seat as far back as possible so that it is as
far as possible from the front passenger's
airbag. While doing this, make sure the seat
can be adjusted all the way. A child in a child
safety seat on the front passenger's seat can
receive a severe impact if the front passeng-
er's airbag deploys, which increases the risk
of serious or fatal injury.
— Replace the child safety seat after an acci-
dent because there could be damage that is
not visible.
— Even if a child is not sitting in the child safe-
ty seat, the child safety seat must be se-
cured. An unsecured child safety seat may
be thrown through the vehicle interior dur-
ing sudden braking maneuvers or an acci-
dent.
