in streaking. This can affect the rain sensor
function. Check your windshield wiper
blades regularly.
— The washer fluid nozzles for the windshield
washer system are heated when the ignition
is on if the outside temperature is low.
— When stopping temporarily, such as at a
traffic light, the speed of the windshield
wipers automatically reduces by one level.
— Certain settings are automatically stored
and assigned to the active user.

Additional safety belt functions
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
In certain driving situations, safety belts may be
tightened with reversible belt tensioners when
you start driving. 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.

ZA 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.

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 59. 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

68
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.
G) Tips
If you are transporting children in the vehicle,
read the information and follow the safety
precautions > page 72.
Safety systems monitoring
The ka indicator light in the instrument cluster
monitors the safety systems such as the airbags
(including the control modules, sensors, and wir-
ing) and the belt tensioners. It turns on when you
switch the ignition on and turns off after several
seconds.

If the ka indicator light does not turn on when
the ignition is switched on, does not turn off af-
ter several seconds, or turns on or flashes while
driving, 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.

Sitting correctly and safely

may be severely damaged from the accident. In
these cases, the vehicle occupants will be pro-
tected by the safety belts if they are fastened and
worn correctly.
The deployment of the front passenger's airbag
will depend on the occupancy of the seat
=> page 70.
Each deployed airbag is filled with gas. When this
occurs, the airbag covers open and the airbags
unfold with great force into the deployment zone
within milliseconds. Inflated airbags reduce the
movement of passengers wearing safety belts in
the direction of the impact and thus help to re-
duce the risk of injury. They can help to protect
the head, upper body, and lap, for example. How-
ever, there is the possibility that airbag deploy-
ment can cause injuries.
The airbag system only works when the ignition
is turned on.
If you or other vehicle passengers have physical
limitations that prevent sitting in a correct posi-
tion, modifications to the vehicle may be neces-
sary. For more information, contact an author-
ized Audi dealer or authorized Audi Service Facili-
ty, or call Audi customer support at
1-800-822-2834.
@ Tips
The side curtain airbags in your vehicle have
ejection mitigation functions. This reduces
the risk of being ejected from the vehicle inte-
rior during an accident, especially in the event
of a vehicle rollover.
Advanced a ea)

Fig. 69 Headliner: indicator light to display the status of
the front passenger's airbag
70
The Advanced Airbag System in your vehicle has
been certified to comply with the requirements
of the United States Federal Motor Vehicle Safety
Standard (FMVSS) 208, as well as Canada Motor
Vehicle Safety Standard (CMVSS) 208 as applica-
ble at the time your vehicle was manufactured.
According to these requirements, the front Ad-
vanced Airbag System on the passenger’s side
has been certified for “suppression” for infants
approximately 12 months old and younger, and
for “low risk deployment” for children aged 3 to
6 years old (as defined in the standard).
The advanced airbag system will activate or deac-
tivate the front passenger's airbag based on the
occupancy of the seat. If a front airbag deploys
during an accident, the deployment force will
adapt to the passenger.
Components
The advanced airbag system consists of the fol-
lowing components:
— Front airbags in the steering wheel and in the
instrument panel on the front passenger's side:
these can protect the front passengers during
an accident
— Passenger occupant detection sensor in the
front passenger's seat: this detects if the front
passenger's seat is occupied (for example, by a
person or a small child in a child safety seat)
— Seat position sensors on the front seats: these
determine the distance between the seat and
the steering wheel or instrument panel
— Sensors in the front seat belt latch: these de-
tect if the safety belts are fastened
—The PASSENGER AIR BAG OFF #;, ON @
indicator light in the headliner: this indicates if
the front passenger's airbag is activated or de-
activated
- ka 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

8W1012721BB
Sitting correctly and safely

occupant detection sensor measures the electri-
cal capacity on the front passenger’s seat. The
passenger'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.
Meaning of PASSENGER AIR BAG OFF 3; ON
® indicator light
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 8¥;: 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.
— An adult or individual of similar size in the
front passenger's seat: the front passenger's
airbag must be activated, so
PASSENGER AIR BAG ON ® must remain
on.
— An individual of smaller size (for example, an
adolescent or small adult) in the front pas-
senger's seat: the front passenger's airbag
must be activated, so
PASSENGER AIR BAG ON @ must remain
on.
— Child in a child safety seat on the front pas-
senger's seat: the front passenger's airbag
must be deactivated, so
PASSENGER AIR BAG OFF #%; must remain
on.
— Front passenger's seat not occupied: the front
passenger's airbag must be deactivated, so
PASSENGER AIR BAG OFF ®, must remain
on.

ZA\ WARNING
— An adult or a person with a small stature
(such as a young person or small adult) seat-
ed on the front passenger's seat will not be
protected by the passenger's airbag in the
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 59 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
