Front passenger's exterior mirror tilt
function*
Requirement: the knob must be in the position
for the front passenger’s exterior mirror.
The mirror surfaces tilt slightly when reverse
gear is selected to provide a better view, for ex-
ample of the edge of the curb.
You can adjust the mirror surface by turning the
knob in the desired direction. When you move
out of reverse and into another gear, the new
mirror position is stored and assigned to the key
you are using.
The mirror goes back into its original position
once you drive forward faster than 9 mph
(15 km/h) or turn the ignition off.

Z\ WARNING
Curved mirror surfaces (convex) enlarge the
field of vision. However, they make objects in
the mirror appear smaller and farther away.
When using these mirrors to estimate your
distance to vehicles behind you when chang-
ing lanes, you could estimate incorrectly,
which increases the risk of an accident.

@) Note
If the mirror housing was moved by force (for
example, by running into an object when ma-
neuvering the vehicle), the mirror must be
folded all the way in using the power folding
function. The mirror housing must not be
moved back into place by hand because this
could impair the function of the mirror mech-
anism.
@ Tips
If the power adjusting function malfunctions,
the glass in both mirrors can be adjusted by
pressing on the edge of it by hand.

lyte fluid can lead to irritation of the air-
ways, especially in people with asthma or
other respiratory conditions. Take deep
breaths immediately after leaving the vehi-
cle or, if this is not possible, open all of the
doors and windows as wide as possible.
— If electrolyte fluid comes into contact with
the eyes, flush them thoroughly with plenty
of clean water for at least 15 minutes and
then seek medical attention.
— If electrolyte fluid comes into contact with
the skin, flush the affected area with clean
water for at least 15 minutes, and then
clean with soap and water and seek medical
attention. Clean affected clothing and shoes
thoroughly before wearing again.
— If the fluid was swallowed and the person is
conscious, flush the mouth with water for at
least 15 minutes. Do not induce vomiting
unless this is recommended by medical pro-
fessionals. Seek medical attention immedi-
ately.
() Note
If the glass on an automatic dimming mirror
breaks, electrolyte can leak out. This liquid
damages plastic surfaces. Clean this liquid as
quickly as possible, for example with a wet
sponge.

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.

Sitting correctly and safely

The locations of the airbags are labeled with
“AIRBAG”. The following airbags are installed in
your vehicle:
Driver's airbag
Front passenger's airbag
Side airbags
Applies
to: Coupe: Head curtain airbag with
ejection mitigation
©
©0080
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
correct seating position. Airbags are a supple-
mentary restraint system and do not replace
safety belts.
Applies to: Coupe: Airbags may deploy during
head-on, side-impact, or rollover collisions.
Applies to: Roadster: Airbags may deploy during
head-on or side-impact collisions.
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
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 55.
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
Applies to: Coupe
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. 62 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
55
>

Sitting correctly and safely

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 asmall 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
— PASSENGER AIR BAG OFF 8%; ON ® indica-
tor light in the headliner:this indicates if the
front passenger's airbag is activated or deacti-
vated
- 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:
56
— 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 #4, 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.
