Rear parking system
Rear acoustic park assist
Applies to: veh icles w ith parking system (rear)
The rear acoustic pork assist warns you of obsta­
cles or objects behind your car.
Description
The rear acous tic p arking assist system de ter ­
mines the d istance o f the veh icle from an obsta -
104 cle using ultrasonic sensors
. There are 4 sensors
in the rear bumper.
The range at whi ch the sensors s tart to measure
i s
abou t:
To the s ide 2 ft (0 .60 m)
Cente r rear 5.2 ft (1.60 m)
Activation
Acoustic parking assist is act ivated automatically
whe n
revers e gear is engaged. A brief tone con­
firms that the system is a ctivated.
Warning tones
D istance warning is give n by warni ng tones wh ich
are generated by the rear signal generator . The
vo lume and the p itch of the warn ing tones can be
adjus ted in the M MI*
¢ page 105.
Rever sing
D istance warning when reversing starts when an
obstacle is detected in t he range of the parking
ass ist system . As the distance dec reases, the
time interva l between the audib le tones becomes
sho rter.
When the distance is less than 1ft (0 .30 m), the
tone becomes cont inuo us. At th is point you
shou ld stop backing up .
Please note that low objects already s ignalled by
a war ning can d isappear from the system's detec ­
tion range and wi ll not cont inue to be s ignalled .
If the distance to an obstacle remains the same,
the volume of the d istance warning is gradually
reduced after about 4 seconds (th is does not ap ­
ply i n the continous to ne range) . Approaching an­
othe r obstacle will result in the distance warn ing
sounding at the normal volume aga in.
Malfunctions in the system
If a warning tone is audible for about five sec­
o nds when you turn on the ignition, there is a
malfunction in the system . Have the prob lem
cor rected by you r authorized Audi dea le r.
Keep the sensors in the rear bumper clean and
free from ice so that the acoustic park ass ist sys -
tem can function properly . .,.

,&_ WARNING
-Sensors have dead spaces in which objects
cannot be detected. Be especia lly alert for
small children and animals, since they are not always detected by the sensors.
- The acoustic parking system is not a substi­
tute for the dr iver's own caution and alert­
ness. Ultimate respons ibility always remains
with the driver during parking and sim ilar
maneuvers . Always watch where you are
dr iv ing .
- You should always adjust the volume and
frequency of the warning tones so that you
can eas ily hea r the acoustic distance wa rn­
ing even if the radio is p lay ing, the air-cond i­
tioner blower is on High or there is a high
level of ou ts ide no ise .
- Check the settings whenever anyone e lse
has driven the vehicle before you.
(D Note
- Remember that low obstacles for which a
warning has already been issued may "dive"
below the system's sensing zone if the vehi­
cle is being backed up closer. In this case,
the war ning sound shutting off does
not in­
dicate that you have cleared the obstacle.
Instead, impact is imm inent.
- Objects such as tra iler hitches, chains, nar­
row posts or fences cove red by a th in laye r
of pa int may not always be detected by the
system. They can still damage your vehicle
wi thout warn ing.
{O) Tips
Keep the senso rs in the rear bumper clean
and free of snow and ice so that t he acous tic
parking assist sys tem can f unction properly.

Rear view camera coverage area
The M MI display shows t he area cove red by the
rear view camera
¢ fig . 122 (!). Objects that are
not in the a rea covered @are not shown on the
MMI display.
We recommend tha t you prac tic e parking wit h
the rear v iew camera in a t raffic -free location or
parking lot to become familiar with the system,
the orientat ion lines, and their function . When
do ing th is, there should be good light and weath­
er condit ions.

Error messages
App lies to: vehicles wit h parking system ( rea r, w ith rea r view
camera)
If a warning tone is audible for about five sec­
onds when you turn on the ignition, there is a
malfunction in the system. Have the problem
corrected by your authorized Audi dealer .
Keep the sensors in the rear bumper clean and
free from ice so that the acoustic park assist sys­
tem can function properly.

Driving safety
-the safety belts with belt tensioners
- the windshield frame
- the rollover sensors
The active rollover protection system provides
additional safety in the event of a rollover. With­
in milliseconds, sensors deploy two rollbars lo­
cated behind the headrests in the rear seats
¢fig. 132 .
The rollbars, reinforced windshield frame and
belt tensioners help protect front and rear pas­
sengers in the event of a rollover.
The rollover protection system functions when
the power top is both open and closed.
A WARNING
Do not use the area behind the rear seat
headrests
¢fig. 131 as a storage area. This is
the area where the rollbars deploy.
If the roll­
over protection system is triggered, objects
placed there can be propelled through the ve­
hicle and make it more difficult for the roll­
bars to deploy. This increases the risk for seri­
ous or life-threatening injuries.
When is rollover protection deployed?
Rollover protection deploys in o collision or roll­
over.
Depending on the collision, sensors throughout
the vehicle and the control module trigger the
ro llov er system to deploy.
Fo r safety reasons, rollover protection also de­
ploys during front, side and rear collisions above
a certain level of severity.

Retracting rollover protection
Fig. 133 Deployed rollbar wit h release loop.
Fig. 134 Deployed rollbar wit h power top frame facing up­
ward .
If the rollover protection has triggered but the
vehicle was not involved in an accident, you can
retract the rollover protection yourself in an
emergency. Drive to your authorized Audi dealer
or qualified repair facility immediately to have
the malfunction corrected.
With the power top open
... Pull the loop upward in the direction of the ar­
row and hold it in place~

Safe ty belts
Unfastening safety belts
Unbuckle the safety belt with the red relea se
button only after the vehicle has stopped .


Fig. 145 Rele asing th e to ngu e fro m the buck le
.. Push the red release button on the buckle
Q fig. 145 . The belt tongue will spring out of
the buckle
Q ,& .
.. Let the belt wind up on the retractor as you
guide the belt tongue to its stowed position.
A WARNING
Never unfasten safety belt while the vehicle is
moving . Doing so will increase your risk of be­
ing injured or k il led.
Improperly worn safety belts
a
~ 0 :i: .. 0J
Incorrectly positioned safety belts can cause se­
vere injuries .
Wearing safety belts improperly can cause seri­
ous injury or death . Safety belts can only work
when they are correctly positioned on the body .
Imp roper seating positions reduce the effect ive­
ness of safety belts and wi ll
even i ncrease the
risk of injury and death by mov ing the safety bel t
to cr it ica l areas of the body. Imp roper seating
positions a lso increase the risk of se rio us inj ury
and death when an airbag deploys and strikes an
occupant who is not in the correct seating pos i­
tion . A
drive r is responsible fo r the safety of all
veh icle occupants and especially for children.
Therefore:

A WARNING
Improperly worn safety belts increase the risk
of ser ious personal injury and death whenever
a veh icle is being used .
- Always make sure that all veh icle occupants
are cor rectly restrained and stay in a correct
seating position whenever the vehicle is be­ ing used.
- Always read and heed all WARNINGS a nd

Belt tensioners
How safety belt pretensioners work
In front, side and rear-end collisions above a
particular sev erity, saf ety belts are tensioned au­
tomatically .
The safety belts are eq uipped w ith safety belt
pretensioners. The system is activa ted by sensors
in front, side and rear -end collisions of great se­
verity. This tightens the be lt and takes up belt
s lack
Q .&. in Service and disposal of safety belt
pretensioner on page 129 .
Taking up the slack
helps to reduce forward occupant movement dur­
i ng a collis ion .
@ Note
Never let the belt remain over a rear seatback
that has been folded forward.
@ Tips
The sa fety belt pretensioner can only be acti­
vated once .
- The safety belt pretensioners do not deploy
in minor frontal, side and rear -end coll i­
sions.
- When the safety belt pretensioners are acti­
vated, a f ine dust is released. This is normal
and is not caused by a fire in the veh icle.
- The relevant safety requirements must be
observed when the vehicle or components
of the system are scrapped. An authorized
Audi dealer or qua lified workshop is familiar
w ith these regu lations and will be pleased
to pass on the information to you. .,._

greater detail below. Because the front passen­
ger seat contains important parts of the Ad­
vanced A irbag System, you must take care to pre ­
vent it from being damaged. Damage to the seat
may prevent the Advanced Airbag for the front
passenger seat from doing its job in a crash .
The front Ad vanced Airb ag S ystem con sis ts
of the follo wing :
-Crash sensors in the front of the vehicle that
measure vehicle acceleration/decelerat io n to
provide information to the Advanced Airbag
System about the severity of the crash .
- An electronic control unit, with integrated
crash sensors for front and side impacts . The
contro l unit "decides" whether to fire the front
airbags based on the information received from
the crash sensors. The control unit also "de ­
cides" whether the safety be lt pretensioners
shou ld be activated.
- An Advanced Airbag with gas generator and
contro l valve for the driver inside the steering
whee l hub .
- An Advanced Airbag with gas generator and
contro l valve inside the instrument pane l for
the front passenger.
- A weight -sensing mat under the upho lstery
padding of the front passenger seat cushion
that measures the total weight on the seat . The
information registered is sent continuously to
the electron ic control unit to regulate deploy­
ment of the front Adva need A irbag on the pas­
senger side.
- An airbag monitoring system and indicator
light i n the instrument cluster
¢page 140.
-A sensor in each front seat registers the dis­
tance between the respective seat and the
steering wheel or instrument panel. The infor­
mation reg istered is sent cont inuous ly to the
electronic control unit to regulate deployment
of the fro nt Adv a need A irbags.
- T he
PASS EN GE R AIR BAG OFF light comes on
and stays on in the center of the instrument
pane l¢
page 140, fig . 149 and tells you when
the front Advanced Airbag on the passenge r
side has been turned off.
- A sensor below the safety belt latch fo r the
front seat passenger to meas ure the tension on
Airb ag sys tem
the sa fety belt. The tension on the safety belt
and the weight registered by the weight-sens­
ing mat help the control unit "decide" whether
the front airbag for the front passenger seat
should be turned off or not¢
page 131, Child
restraints on the front seat -some important
things to know.
- A sensor in the safety belt latch for the driver
and for the front seat passenger that senses
whether that safety belt is latched or not and
transmits this information to t he electronic
cont rol un it.
_& WARNING
Damage to the front passenge r seat can pre­
vent the front airbag from working properly.
- Imp roper repair or disassembly of the front
passenger and driver seat will p revent the
Advanced Airbag System from f unctioning
properly.
- Repairs to the front passenger seat must be
performed by qualified and properly trained
workshop personne l.
- Never remove the front passenger or driver
seat from the vehicle.
- Never remove the upholstery from the front
passenger seat.
- Never d isassemble o r remove par ts from the
seat o r disconnect w ires from it.
- Never carry sh arp objects in your pocke ts or
p lace them on the seat. If the weight-sens­
ing mat in the passenger seat is punctu red
it cannot work proper ly.
- Never carry things on your lap or carry ob­
jects on the passenger seat. S uch items can
increase the weight reg istered by the
weight-sensing mat and send the wrong in­
formation to the airbag control unit.
- Never store items under the front passenger
seat. Parts of the Advanced Airbag System
under the passenger seat could be dam­
aged, p reventing them and the airbag sys­
tem from working p roper ly.
- Never p lace seat covers or replacement up­
holstery that have not been specifically ap­
p roved by A udi on the front seats.
- Seat covers can prevent the Advanced A ir­
bag System from recognizing chi ld
137

Airbag syste m
restraints or occupants on the front passen­
ger seat and prevent the side airbag in the
seat backrest from deploying properly.
- Never use cushions, pillows, blankets or
similar items on the front passenger seat.
The additional padding will prevent the
weight-sens ing mat in the seat from accu­
rately reg istering the ch ild restraint or per­
son on the seat and prevent the Advanced
Airbag System from funct ioning prope rly.
- If you must use a child restraint on the front
passenge r seat and the child restraint man­
ufact urer's instructions require the use of a
towel, foam cushion or something else to properly position the chi ld restraint, make
certain that the
PASSENGER A IR BAG OFF
light comes on and stays on whenever the
child restraint is installed on the front pas­
senger seat.
- If the
PAS SENGER AIR BAG O FF light does
not come on and stay on, immediately in­
stall child restraint in a rear seating position and have the airbag system inspected by
you r authorized Aud i deale r.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the side
ai rbags supplement the protection offered by the
front three-point safety belts with pretensioners and load limiters and the adjustable head re ­
stra ints to help reduce the r isk of injury in a wide
range of accident and crash situations. Be sure to
read the important information about safety and heed the WARNINGS in th is chapter .
Deployment of the Advanced Airbag System and
the activation of the safety belt pretensioners de­
pend on the deceleration measured by the crash
sensors and registered by the electronic control
unit . Crash severity depends on speed and decel­
eration as we ll as the mass and stiffness of the
vehicle or object involved in the crash.
On the passenger s ide, regardless of safety belt
use, the a irbag will be t urned off if the weight on
the passenge r seat is less than the amount p ro­
g rammed in the e lectron ic cont rol unit . T he front
1 38
airbag on the passenger side will also be turned
off if one of the child safety seats that has been
certified under Federal Motor Vehicle Safety
Standard 208 has been recogn ized on the seat.
The

.&_ WARNING
To reduce the risk of injury when an airbag in­
f lates, always wear safety belts properly.
- I f you are unrestrained, leaning forward, sit­
ting sideways or ou t of position in any way,
your ris k of injury is much highe r.
- You will a lso receive ser ious injuries and

veh icle, changing the stiffness of the suspens ion,
including the spr ings, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic control unit . Some suspens ion changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in wh ich it would not deploy if
the changes had not been made. Other ki nds of
changes may reduce the force levels measured by
the sensors and preven t the airbag from deploy­
ing when it should .
A WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced A irbag performance and in ­
crease the risk of serious personal injury in a
crash.
- Never install suspension components that
do not have the same performance charac­
teristics as the components originally insta l­
led on your veh icle .
- Never use tire-rim comb inations 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 electronic control module and prevent
the Advanced A irbag System from working
properly.
- Always make sure that nothing can inte rfe re
w ith the safety belt buckles and that they
are not obstructed.
Knee airbags
Description of knee airbags
Applies to: vehicles with knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front seat
occupants.
Fig. 150 Driver's knee a irbag
The driver knee airbag is in the instrument panel
underneath the steering whee l~
fig. 150, the
knee airbag for the passenger is at about the
same height in the instrument panel underneath
the g love compartment.
The knee airbag offers additional protection to
the driver's and passenger's knees and uppe r and
l ower thigh areas and supp lements the protec­
tion provided by the safety belts .
If the front airbags deploy, the knee airbags also
deploy in frontal collis ion s when the deployment
th reshold stored in the control unit is met

about front airbags.
In addition to their normal safety funct ion, safe-
ty belts help keep the driver or front passenger in
