@
Fig. 146 Driving s it u ations
Fig. 147 Rear of the veh icle: pos it ion of the sensors
Side assist functions at speeds above approxi­
mately 9 mph (15 km/h) .
@Approaching vehicles
In certain cases, a vehicle will be classified as
critical for a lane change even i f it is still some ­
what far away. The faster a vehicle approaches,
140
the sooner the display in the exterior mirror will
turn on .
@Vehicles traveling with you
Vehicles traveling with you are indicated in the
exter ior mirror if they are classified as critical for
a lan e change . All vehicles detected by side assist
are indicated by the time they enter your "blind
spot", at the latest .
@ Vehicles you are passing
If you slow ly pass a vehi cle that side assist has
detected (the differe nce in speed between the
vehicle and your vehicle is less than approximate­
l y 9 mph (15 km/h)), the disp lay in the exterior
mirror turns on as soon as the vehicle enters your
blind spot.
The display wi ll not turn on if you quickly pass a
vehicle that side assist has detected (the differ­ ence in speed is greater than approximate ly 9
mph (15 km/h)) .
Functional limitations
The radar sensors are designed to detect the lef t
and right adjacent lanes when the road lanes are
the normal width . In some situations, the display
in the exterior m irror may turn on even though
there is no vehicle located in the area that is criti­
ca l for a lane change. For example:
- If the lanes are narrow or if your
are dr ivin g on
the edge of your lane. If this is the case, the
system may have detected a vehicle in another
lane that is
not adjacent to your cur rent lane.
- If you are driving through a curve. Side ass ist
may react to a vehicle that is one lane over
from the adjacent lane.
- If side assist reacts to other objects (such as
high or displaced guard ra ils).
- In poor weather conditions. The side ass ist
functions are limited.
Do not cover the radar
sensors ¢ fig. 147 with
stickers, deposits, bicycle wheels or other ob ­
j ects, because they will impair the function. Do
not use s ide assist when towing a trai ler. For in-
format ion on cleaning,
see ¢ page 347. .,..

A WARNING 1=
- Always pay attention to traffic and to the
area around your vehicle. Side assist cannot
replace a dr iver's attention. The dr iver alone
is always responsible for lane changes and
similar driving maneuvers.
- In some situat ions, the system may not
function or its funct io n may be limited. For
example:
- If vehicles are approaching or being left
behind very quickly. The display may not
turn on in time.
- In poor weather conditions such as heavy
rain, snow or heavy mist.
- On very wide lanes, in tight curves, or if
there is a rise in the road surface. Vehicles
in the adjacent lane may not be detected
because they are outside of the sensor
range.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. Th is can impa ir the system. Have
an authorized Audi dealer or authorized Audi
Serv ice Facility check their function .
(Di Tips
If the window glass in the driver's door or
front passenger's door has been tinted, the
disp lay in the exterior mirror may be incor­
rect.

Parking systems
General information
A ppl ies to: ve hicles w ith parking system plus/rearview cam ­
era
Depending on your vehicle's equipment , various
parking aids will help you when parking and ma­
neuvering.
The
parking system plus assists you when park­
ing by audibly and visually indicating objects de­
tected
in front of and behind the vehicle
¢page 147.
The rearview camera shows the area behind the
vehicle in the Infotainment system display. This display assists you when you are cross or parallel parking. The parking system plus functions are
also available ¢
page 148.
A WARNING
-
-Always look for traffic and check the area
around your vehicle by looking at it directly
as well. The parking system cannot replace
the driver's attention. The driver is always
responsible when entering or leaving a park­
ing space and during similar maneuvers .
-Please note that some surfaces, such as
clothing, are not detected by the system .
-Sensors and cameras have blind spots in
which people and objects cannot be detect­
ed . Be especially cautious of small children
and animals .
-Always pay attention to the area around the
vehicle -us ing the rearview mirror, too.
-The sensors can be displaced by impacts or
damage to the radiator grille, bumper,
wheel housing and the underbody . The park­
ing system may be impaired as a result.
Have an authorized Audi dealer or author­
ized Audi Service Facility check their func­
tion .
(D Note
-Some objects are not detected or displayed
by the system under certain circumstances:
-objects such as barrier chains, trailer draw
bars, vertical poles or fences
146
-objects above the sensors such as wall ex­
tensions
-objects with certain surfaces or structures
such as chain link fences or powder snow
-If you continue driving closer to a low ob­
ject, it may disappear from the sensor range. Note that you will no longer be
warned about this obstacle.
-Keep enough distance from the curb to re­
duce the risk of damage to the rims.
(D Tips
-T he system may provide a warning even
though there are no obstacles in the cover­ age area in some situations, such as:
-certain road surfaces or when there is tall
grass .
-external ultrasonic sources such as from
cleaning vehicles.
-in heavy rain, snow, or thick vehicle ex­
haust.
-We recommend that you practice parking in
a traffic-free location or parking lot to be­
come familiar with the system . When doing
this, there shou ld be good light and weath­
er conditions.
-You can change the volume and pitch of the
signals as well as the display¢
page 150.
-What appears in the infotainment display is
somewhat time-delayed .
-The sensors must be kept clean and free of
snow and ice for the parking aid to operate .

Airbag system
A WARNING
A child in a rearward-facing child safety seat
installed on the front passenger seat will be
seriously injured and can be killed if the front
airbag inflates - even with an Advanced Airbag
System.
- The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the child safety seat and child against the backrest, center armrest, door
or roof.
-Always install rear-facing child safety seats on the rear seat.
- If you must install a rearward facing child
safety seat on the front passenger seat be­ cause of exceptional circumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rear -facing child safety seat in a rear
seating position and have the airbag system inspected by your Audi dealer.
A WARNING
Objects between you and the airbag will in­
crease the risk of injury in a crash by interfer ­
ing with the way the airbag unfolds or by be­
ing pushed into you as the airbag inflates.
- Never hold things in your hands or on your
lap when the vehicle is in use .
- Never transport items on or in the area of
the front passenger seat . Objects could
move into the area of the front airbags dur­
ing braking or other sudden maneuvers and
become dangerous projectiles that can
cause serious personal injury if the airbags
inflate.
- Never place or attach accessories or other
objects (such as cup holders, telephone
brackets, large, heavy or bulky objects) on
the doors, over or near the area marked
"AIRBAG" on the steering wheel, instru­
ment panel, seat backrests or between
those areas and yourself . These objects
could cause injury in a crash, especially
when the airbags inflate .
- Never recline the front passenger's seat to
transport objects. Items can also move into
278
the area of the side airbag or the front air­
bag during braking or in a sudden maneu­
ver. Objects near the airbags can become projectiles and cause injury, particularly
when the seat is reclined .
- Never place or transport objects on the
front passenger seat. Objects on the front
passenger seat could cause the capacitive
sensor in the seat to signal to airbag system
that the seat is occupied by a person when it
in fact is not, or that the person on the seat
is heavier than he or she actually is. The
change in electric capacitance because of
such objects can cause the passenger front
airbag to be turned on when it should be
off, or can cause the airbag to work in a way
that is different from the way it would have
worked without objects on the seat .
- Always make sure that there is nothing on
the front passenger seat that will cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that the seat is occupied by a person when it is
not , or to signal that it is occupied by some ­
one who is heavier than the person actually
sitting on the seat. The presence of an ob­
ject could cause the passenger front airbag
to be turned on when it should be off, or
could cause the airbag to work in a way that
is different from the way it would have
worked without the object on the seat .
A WARNING
The fine dust created when airbags deploy can
cause breathing problems for people with a
history of asthma or other breathing condi­
tions .
- To reduce the risk of breathing problems,
those with asthma or other respiratory con­
ditions should get fresh air right away by
getting out of the vehicle or opening win­
dows or doors.
- If you are in a collision in which airbags de­
ploy , wash your hands and face with mild
soap and water before eating.
- Be careful not to get the dust into your eyes,
or into any cuts or scratches.

seat into its rearmost position in the seat's
fore and aft adjustment range, as far away
from the airbag as possible. The backrest must be adjusted to an upright position.
Make sure that the
PA SSEN GER AIR BAG
OFF
light comes on and stays on all the time
whenever the ignition is switched on.
,& WARNING
- If the PA SSENGER AIR BAG OFF light does
not go out when an ad ult is sitting on the
front passenger seat after taking the steps
described above, make sure the adu lt is
properly seated and restrained at one of the
rear seat ing positions.
- Have the airbag system inspected by your
Audi dealer before transporting anyone on
the front passenger seat.
(D Tips
If the capacitive passenger detection system
determines that the front passenger seat is
empty, the fronta l airbag on the passenger
side will be turned off, and the
P ASSE NGER
A IR BAG OFF light will stay on.
Repair , care and disposal of the airbags
Parts of the airbag system are installed at many
d ifferent places on your Aud i. Install ing, remov­
ing, servic ing or repa iring a part in an area of the
veh icle can damage a pa rt of an airbag system
and prevent that system from working properly
in a co llision.
There are some important things you have to
know to make sure that the effectiveness of the
system w ill not be impaired and that discarded
components do not cause injury or pollute the
environment .
,& WARNING
Improper care, servicing and repair proce­
dures can increase the r isk of personal injury
and death by preventing an airbag from de­
ploying when needed or deploying an airbag
unexpectedly:
282
- Never cover, obstruct, or change the steer­
ing wheel horn pad or airbag cover or the in­
strument panel or modify them in any way.
- Never attach any objects such as cup holders
or telephone mountings to the surfaces cov­
ering the a irbag un its.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one mois­
tened w ith plain water. Solvents or cleaners
could damage the airbag cover or change
the st iffness or strength of the material so
that the airbag cannot deploy and protect properly.
- Never repair, adjust, or change any parts of
the airbag system.
- All work on the steering wheel, inst rument
panel, front seats or e lectr ica l system ( in­
cluding the instal lation of a udio eq uipment,
cellular telephones and CB radios, etc.)
m ust be performed by a qualified technician
who has the training and specia l equipment
necessary.
- For any work on the airbag system, we strong ly recommend that you see your au­
thorized Audi dealer or qualified workshop.
- Never modify the front bumper or parts of
the vehicle body.
-Always make sure that the side airbag can inflate without interference:
- Never install seat covers or replacement upholstery over the front seatbacks that
have not been specif ica lly approved by
A udi.
- Never use additional seat c ushions that
cover the areas where the side airbags in­
flate.
- Damage to the orig inal seat cove rs or to
the seam in the area of the s ide airbag
module mus t always be repai red immedi ­
ate ly by an authorized Audi dealer.
- The a irbag sys tem can deploy on ly once. Af­
ter an airbag has been deployed, it m ust be
replaced with new replacement parts de ­
signed and approved especia lly for your
Audi model version . Replacement of com­
plete airbag systems or airbag components
must be performed by qua lified workshops
only . Make sure that any airbag service

Child safety
-Always make sure that the PASSENGER
AIR BAG OFF
light comes on and stays on
all the time whenever the ignition is
switched on .
-If the PASSENGER AIR BAG OFF light
does not come on and stay on, immediate­
ly install the forward-facing child safety
seat in a rear seating position and have
the airbag system inspected by your au­
thorized Audi dealer.
- Always buckle the child safety seat firmly
in place even if a child is not sitting in it. A
loose child safety seat can fly around dur­
ing a sudden stop or in a collision .
-Always read and heed all WARNINGS
whenever using a child restraint in a vehi­
cle ¢
page 258, Safety belts,~ page 267,
Airbag system and ~ page 292, Impor­
tant information.
(D Tips
Always replace child restraints that were in­
stalled in a vehicle during a crash. Damage to
a child restraint that is not visible could cause
it to fail in another collision situation.
Advanced front airbag system and children
Your vehicle is equipped with a front "Advanced
Airbag System" in compliance with United States Federal Motor Vehicle Safety Standard (FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 208 as applicable at the time
your vehicle was manufactured.
The Advanced Airbag system in your vehicle has
been certified to meet the "low-risk " require­
ments for 3- and 6-year old children on the pas­
senger side and small adults on the driver side.
The low risk deployment criteria are intended to
reduce the risk of injury through interaction with
the airbag that can occur, for example, by being
too close to the steering wheel and instrument
panel when the airbag inflates. In addition, the
system has been certified to comply with the
"suppression" requirements of the Safety Stand­
ard, to turn off the front airbag for infants up to 12 months who are restrained on the front pas-
294
senger seat in child restraints that are listed in
the Standard.
Even though your vehicle is equipped with an Ad­
vanced Airbag system, all children, especially
those 12 years and younger, should always ride
in the back seat properly restrained for their age
and size. The airbag on the passenger side makes
the front seat a potentially dangerous place for a child to ride. The front seat is not the safest place
for a child in a forward-facing child safety seat. It
can be a very dangerous place for an infant or a
larger child in a rearward-facing seat.
The vehicle's Advanced Airbag System has a ca­ pacitive passenger detection system in the front
passenger seat cushion that can detect the pres­
ence of a baby or a child in a child restraint sys­
tem on this seat.
The capacitive passenger detection system regis ­
ters the changes that result in an electrical field
when a child, a child restraint , and a baby blanket
are on the front passenger seat. The change in
the measured capacitance due to the presence of
a child, a child restraint, and a baby blanket on
the front passenger seat is related to the child
restraint system resting on the seat. The meas­
ured capacitance of a child restraint system var­
ies depending on the type of system and specific
make and model.
The electrical capacitance of the various types, makes, and models of child restraints specified
by the U.S.National Highway Traffic Safety Ad­
ministration (NHTSA) in the relevant safety
standard are stored in the Advanced Airbag Sys ­
tem control unit together with the capacitances
typical of infants and a 1-year old child. When a
child restraint is used on the front passenger
seat with a typical 1 year-old infant, the Ad­
vanced Airbag System compares the capacitance
measured by the capacitive passenger detection
system with the data stored in the electronic con­
trol unit .
