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 73.
Safety systems monitoring
The Ba 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.

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.

Description



RAZ-0239

Fig. 59 Airbag overview image (enlarged section: deployed airbags)
The locations of the airbags are labeled with
“AIRBAG”. The following airbags are installed in
your vehicle:
@ Driver's airbag
@ Front passenger's airbag
@® Front and rear side airbags, if applicable
@ Side curtain airbags
© Knee airbags
Airbags offer the best possible protection in your
vehicle during an accident when they are used to-
gether with safety belts that are fastened cor-
rectly, and when passengers are sitting in the cor-
rect seating position. Airbags are a supplementa-
ry restraint system and do not replace safety
belts.
Airbags may deploy during front-impact, side-im-
pact, or rollover accidents.
The deployment area for the airbag system can-
not be defined for every situation, since the cir-
cumstances surrounding accidents can vary wide-
ly. Factors that play an important role include the
70
condition of the object that the vehicle hits (hard
or soft), the angle of impact, vehicle speed, etc.
The deciding factor for the deployment of the air-
bag system is the deceleration that occurs during
an accident. Sensors in the vehicle are designed
to detect the severity of an accident in conjunc-
tion with the control module, and to provide a
targeted and timely deployment of the restraint
system. If the vehicle deceleration that is meas-
ured during an accident is below the specified
reference values in the control module, then the
airbags will not deploy, even though the vehicle
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 71.
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 airbag system

Fig. 60 Headliner: indicator light to display the status of
the front passenger's airbag
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 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 vents below the windshield. The windshield
defogger* is also switched on at low outside tem-
peratures. The ¥ button will flash. Recirculation
mode switches off. The temperature should be
set at +72°F (22°C) or higher. Depending on the
outside temperature, the A/C cooling mode may
automatically switch on.
& Rear window defogger
The rear window defogger only operates when
the engine is running. It switches off automati-
cally after 10 to 20 minutes, depending on the
outside temperature.
To prevent the rear window defogger from
switching off automatically, press and hold &¥ for
more than three seconds. This is stored until the
ignition is switched off.

child safety lock is active and operation is blocked
> page 42.
Ionizer
Applies to: vehicles with ionizer
Hazardous particles and germs in the air may be
reduced through ionization. This will produce
better air quality inside the vehicle.
&* Fragrance
Applies to: vehicles with fragrance function
The fragrance function will dispense a scent in
the vehicle interior. It is dispensed through the
front outer vents. This will produce a pleasant
scent. The fragrance is time-delayed, especially
at low or high temperatures. You can adjust the
fragrance function > page 88.
Residual heat
The residual heat from the coolant is used to
heat the vehicle interior. To use this function,
press and hold {8 for more than two seconds
while the ignition is switched off. The function
switches off automatically after about 15 mi-
nutes.

Z\ WARNING
— You should not use the recirculation mode
for an extended period of time, because no
fresh air is drawn in and the windows can
fog when cooling mode is switched off. This
increases the risk of an accident.
— Individuals with reduced sensitivity to pain
or temperature could develop burns when
using the seat heating* function. To reduce
the risk of injury, these individuals should

not use seat heating*.

General information
Sica eel delay
ZA WARNING
— As the driver, you are always completely re-
sponsible for all driving tasks. The assist
systems cannot replace the driver's atten-
tion. Give your full attention to driving the
vehicle, and be ready to intervene in the
traffic situation at all times.
— Activate the assist systems only if the sur-
rounding conditions permit it. Always adapt
your driving style to the current visual,
weather, road, and traffic conditions.
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Store objects securely while
driving.
— For the assist systems to be able to react
correctly, the function of the sensors and
cameras must not be restricted. Note the in-
formation on sensors and cameras
=>page 116.



@ Tips
— Pay attention to applicable local regulations
relating to driving tasks, leaving space for
emergency vehicles, vehicle distance, speed,
parking location, wheel placement, etc. The
driver is always responsible for following
the laws that are applicable in the location
where the vehicle is being operated.
— You can cancel a steering or braking inter-
vention by the system, by braking or accel-
erating noticeably, steering, or deactivating
the respective assist system.
— Always check the assist systems settings be-
fore driving. The settings could have been
changed, for example, by other drivers or if
another personal profile was used.
System limitations
ZA\ WARNING
—The use of an assist system cannot over-
come the natural laws of physics. A collision
cannot be prevented in certain circumstan-
ces.
— Warnings, messages, or indicator lights may
not be displayed or initiated on time or cor-
rectly, for example, if vehicles are approach-
ing very fast.
— Corrective interventions by the assist sys-
tems, such as steering or braking interven-
tions, may not be sufficient or they may not
occur. Always be ready to intervene.
@) Tips
— Due to the system limitations when detect-
ing the surrounding area, the systems may
warn or intervene unexpectedly or too late
in certain situations. The assist systems may
also interpret a driving maneuver incorrectly
and then warn the driver unexpectedly.
— The systems may not function as expected
in unusual driving situations, such as driving
offroad, on unpaved roads, on loose ground,
on inclines, or on grooves in the road.
— The systems may not function correctly in
unclear traffic situations, such as turning
lanes, exit ramps, construction zones, rises
or dips that obstruct visibility, intersections,
toll stations, or city traffic.
— The detection of the surrounding area can
be limited, for example by vehicles driving
ahead or by rain, snow, heavy spray, or light
shining into the camera.
— If accessories have been mounted on the
steering wheel, the ability for the steering
systems to react may be limited.
