Parking systems
General information
App lies to vehicles: with park in g system plus/rear view
camera/peripheral cameras
Depending on your vehicle's equipment, variÂ
ous parking aids will help you when parking
and maneuvering.
The
advanced parking system with rear view
camera
ass ists you when parking by audibly
and v isua lly indicating objects detected
in
front of
and behind the vehicle . The rear view
camera shows the area behind the vehicle in
the Infotainment display. This display assists
you when you are cross or para llel parking
c:;,page 122.
The peripheral cameras assist you with parkÂ
ing and maneuvering. You are aided by various
cameras depending on the vehicle equipment level ¢
page 126. In addition, you are assistÂ
ed by the functions from the sensors
c:;, page 122, Sensors, c:;, page 124 , Visual
display .
A WARNING
-Always look fo r traff ic and check the area
around your vehicle by looking at it diÂ
rect ly as well. The parking system cannot
replace the driver's attention. The driver
is a lways respons ible for safety during
parking and for all other maneuvers.
- Please note that some sur faces, such as
clothing, are not detected by the system .
- Sensors and cameras have blind spots in
which peop le and objects cannot be deÂ
tected. Be especially cautious of children
and animals.
- The sensors can be displaced by impacts
or damage to the radiator grille, bumper,
wheel housing and the underbody. The
parking systems may become impaired
as a result. Have your authorized Audi
dealer or qualified workshop check their
function.
- Make sure the sensors are not covered by
stickers, deposits or any other obstrucÂ
t ions as it may impair the sensor func-

tion. For information on cleaning, refer
to
c:;, page 218.
(D Note
-Some objects are not detected by the
system under certain circumstances:
- Objects such as barr ier chains, trailer
draw bars, vertical poles or fences
- Objects above the sensors such as wall
extensions
- Objects w ith specific surfaces or strucÂ
tures such as chain link fences or powÂ
der snow .
- If you continue driving closer to a low-lyÂ
ing object, it may disappear from the
sensor range. Note that you w ill no lonÂ
ger be warned about this obstacle .
(D Tips
- The system may provide a warning even
though there are no obstacles in the covÂ
erage area in some situations, such as:
- certain road surfaces or for long grass.
- externa l ult rason ic so urces e.g. from
cleaning vehicles.
- heavy rain, snow or thick vehicle ex Â
haust.
- We recommend that you practice parkÂ
ing in a traffic-free location or parking
lot to become familiar w ith the system.
When doing this, there should be good
light and weather cond itions.
- You can change the volume and pitch of
the signals as we ll as the disp lay

Advanced Airbag System components
The front passenger seat in your vehicle has a
l ot of very important parts of the Advanced
Airbag System in it. These parts include the
weight-sens ing mat, sensors, wiring, brackÂ
ets, and more . The function of the system in
the front passenger seat is checked by the
e lectronic control un it when the ign it ion is on .
The control un it mon itors the Advance d Air Â
bag Sys tem and turn s the a irbag i ndica tor
light on when a ma lfunction in t he system
compo nents is detected . The function of the
ai rbag indicator light is described in greater
deta il below. Because the front passenger
seat contains important parts of the AdÂ
va nced A irbag System, you must take care to
prevent it from being damaged . Damage to
the seat may p revent the Advanced A irbag for
the front passenger seat from doing its job in
a crash .
The front Advanced Airb ag System
consists of the following:
- Crash senso rs in the front of the veh icle that
measu re ve hicle accelera tion/decele ra ti on
to provide info rm ation to the Advanced Air Â
bag System abo ut the severity of the crash.

Damage to the front passenger seat can
prevent the front airbag from working
properly.
- Improper repair or disassembly of the
front passenger and driver seat wi ll preÂ
vent the Advanced A irbag System from
functioning properly.
- Repairs to the front passenger seat must
be performed by q ualified and properly
trained workshop personnel.
- Never remove the front passenger or
dr iver seat from the veh icle.
- Never remove the upholstery from the
front passenger seat.
- Never disassemble or remove parts from
the seat or disconnect wires from it.
- Never carry sharp objects in your pockets
or place them on the seat . If the weightÂ
sensing mat in the passenger seat is
punctured it cannot work properly.
- Never carry things on your lap or carry
objects on the passenger seat. Such
items can increase the weight registered
by the weight-se nsing mat and send the
wrong info rmation to the airbag control
unit.
- Never store items under the front pas senger seat. Parts of the Advanced Ai rÂ
bag System under the passenge r seat
c ou ld be damaged, prevent ing them and
the a irbag sys tem from working proper Â
ly .
- N ever place sea t covers or replacement
upholstery that have not been specificalÂ
ly approved by A udi on the fron t seats.
- Seat covers can preven t th e Advanced
Airbag System from recognizing child re Â
st raints or occupants on the front pasÂ
senger seat and prevent the side airbag
in the seat backrest from deploy ing propÂ
er ly.
- Never use cushions, pillows, blankets or
similar items on the front passenger seat. The add itiona l padd ing will prevent
the weight-sensing mat in the seat from
accu rately reg iste ring the c hild restra int
-
or person on the seat and prevent the
Advanced Airbag System from functionÂ
ing p roperly.
- If you must use a child restraint on the
front passenger seat and the child reÂ
straint manufacturer's instructions reÂ
qu ire the use of a towel, foam cushion or
something e lse to prope rly pos ition the
child restraint, make certain t hat the
PASSENGER AIR BAG OFF lig ht comes
on and stays on whenever the ch ild reÂ
straint is installed on the front passen Â
ge r seat .
- If the PASSENGER AIR BAG OFF light
does not come on and stay on, immedi Â
ately insta ll child restraint in a rear seatÂ
ing position and have the ai rbag system
inspected by your Audi dea ler.
How the Advanced Airbag System
components work together
T he front Advanced Airbag System and the
s ide a irbags supp lem ent the p rotection ofÂ
fered by the front three-po int safety belts
with pre tensione rs and load lim iters and the
adjustable head res train ts to help redu ce the
risk of in jury in a wide ra nge of accident and
crash situations . Be s ure to read the imporÂ
tant information about safety and heed the
WARNINGS in th is chapter.
Deployment of the Adv a need Airbag System
and t he activation of the safety belt preten Â
s ioners depend on the deceleration measured
by the crash sensors and registered by the
electron ic co ntrol unit. The amount of inflaÂ
t ion of t he front airbags can a lso be adapted
to the front seat pos ition, depending on the
distance between the respective front seat
and t he steer ing w heel or instrument panel as
regis tered by sensors in the seats. C rash se Â
verity depends on speed and dece leration as
well as the mass and st iffness of t he vehicle
or object involved in the crash .
On t he passenger side, rega rdless of sa fe ty
belt use, the airbag w ill be turned off if the
weight on the passenger seat is less than the ..,.

Airbag monitoring indicator light
Two separate indicators monitor the function
of the Advanced Airbag System: the airbag
monitoring indicator light and the
PASSENÂ
GER AIR BAG OFF
light.
The Advanced Airbag System (including the
electronic control un it, sensor circuits and sysÂ
tem wiring) is monitored continuously to
make sure that it is functioning properly
whenever the ignit ion is on. Each time you
switch on the ignition, the airbag monitoring
indicator light
I (USA models)/ m (Canada
models) will come on for a few seconds (self
diagnost ics).
The system must be inspected when the
indicator light
I (USA models)/fll
(Canada models):
-does not come on when the ignition is
switched on ,
- does not go out a few seconds after you
have switched on the ignition, or
- comes on while driving.
If an airbag system malfun ction is detected,
the indicator light will first start flashing to
catch the driver's attention and then stay on
continuously to serve as a constant reminder
to have the system inspected immediately.
If a malfunction occurs that turns the front
airbag on the passenger side
off, the PASSENÂ
GER AIR BAG OFF
light will come on and stay
on whenever the ignition is on.
A WARNING
An airbag system that is not funct ioning
properly cannot provide supplemental proÂ
tection in a frontal crash.
- If the airbag indicator light

If the PASSENGER AIR BAG OFF light c om es
on
when one o f the conditions listed above is
met, be sure to check the light regularly to
make certa in that the
PASSENGER AIR BAG
OFF
light stays on cont inuo usly whenever the

forth;
- If a strap or tether is be ing used to tie the
child seat to the front passenger seat, make
sure that it is not so t ight that it causes the
weight-sensi ng mat to measure more
weight than is actually on the seat .
If the PASSENGER AIR BAG OFF light still
does not come on
and does not stay on conÂ
t in uous ly (when the ignition is switched on),
- take the child restraint off the front passen -

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag SysÂ
tem performs in a crash. For example, using
tire-rim combinations not approved by Audi,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspenÂ
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag
sensors and sent to the electronic control
unit. Some suspension changes can, for exam ple, increase the force levels measured by the
sensors and make the airbag system deploy in
crashes in which it would not deploy if the
changes had not been made. Other kinds of
changes may reduce the force levels measÂ
ured by the sensors and prevent the airbag
from deploying when it should.
The sensors in the safety belt buckle for the
driver and front passenger seat tell the elecÂ
tronic control module if the safety belt is
latched or not. If the safety belt is being used,
the front airbag will deploy at a slightly highÂ
er rate of vehicle deceleration than if the safeÂ
ty belt is not being used. Therefore, in a parÂ
ticular collision, it is possible that an airbag
will not deploy at a seating position where the safety belt is being used but will inflate at the
position where the safety belt is not being
used . It is important that nothing interfere
with the safety belt buckles so that the senÂ
sors can send the correct information about
safety belt use to the electronic control unit.
A WARNING
Changing the vehicle's suspension includÂ
ing use of unapproved tire-rim combinaÂ
tions can change Advanced Airbag per-
Airbag system 167
formance and increase the risk of serious
personal injury in a crash.
- Never install suspension components
that do not have the same performance characteristics as the components origiÂnally installed on your vehicle.
- Never use tire-rim combinations that have not been approved by Audi.
A WARNING
Items stored between the safety belt buckle and the center console can cause
the sensors in the buckle to send the
wrong information to the e lectronic conÂ
trol module and prevent the Advanced AirÂ
bag System from working properly.
- Always make sure that nothing can interÂ
fere with the safety belt buckles and that
they are not obstructed.

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.

Fi g. 1 71 Side a irbag loca tion in the driver's seat
The side airbags are lo cated i n the sides of the
front seat ba ckrests
¢fig. 171 and the rear
backrest facing the doors. They are identified
by the word "AIRBAG" .
The s ide airbag system ba sically consis ts of :
-the electronic control module and external
s ide impact sensors
- the two side airbags located in the sides of
the front backrests
- two rear side airbags -
the airbag warning light in the ins trument
cluster .
T he airbag system is mon itored elec tronically
to make certain tha t it is f unctioning p roperly
at all times. Each time you switch on the igni Â
tion, the airbag system indicator light will
come on for a few seconds (se lf diagnostics) .
T he side airbag system supplements the safeÂ
ty belts and can help to reduce the risk of in Â
jury to the driver's, front and rear passenger's
u pper torso on the side of the vehicle that is
struck in a side collision. The airbag dep loys
only in side impacts and only when the vehicle
acce lerat ion reg istered by the contro l unit is
high enough. If this rate is be low the refe rÂ
ence value p rog rammed into the control unit,
the side ai rbags will not be triggered, even
t h ough the car may be bad ly damaged as a reÂ
s ul t of the co llision. It is not possib le to deÂ
fine an airbag triggering range that will cover every possib le ang le of impact, since the cirÂ
cumstances will vary cons iderably between
one collis ion and another. Important factors
include, for example, the nature (hard or soft)
of the impacting object, the angle of impact,
vehicle speed, etc. ¢

safety instructions on the side airbag system .
Aside from their normal safety function, safeÂ
ty be lts work to help keep the driver or front
passenge r in position in t he event of a s ide
co llision so that the side airbags can provide
protection.
The airbag system is
not a substitute for your
safety belt . Rather, it is part of the overa ll ocÂ
c u pant restraint system in you r vehicle . A lÂ
ways remember that t he side ai rbag system
c a n only help to protect you if you are wea ring
your sa fety be lt and wearing it p roperly. This
is another reason why you should always wear
your safety belts, not j ust because the law reÂ
quires yo u to do so¢
