Rear parking system
Description
Applies to: vehicles with rear parking system
The rear parking system is an audible parking
aid .
Descrip tion
There is a sensor in the rear bumper cover. If
these detect an obstacle, audible signals warn
you .
Make sure the sensors are not covered by stick­
ers, deposits or any other obstructions as it may
impair the sensor function. For information on
cleaning, see
¢page 275.
The range at which the sensors begin to measure
is approximately:
side 3 ft (0 .90 m)
rear
center 5.2
ft (1.60 m)
The closer you get to the obstacle, the shorter
the interval between the audible signals . A con­
tinuous tone sounds when the obstacle is less
than approximately 1 foot (0.30 meters) away. Do not continue backing up
c:::;, &. in General infor­
mation on page 82,
c:::;,(D in General information
on page 82!
If the distance to an obstacle remains constant,
the volume of the distance warning gradually drops after about four seconds (this does not ap­
ply in the continuous tone range).
Act ivat in g
The rear parking assist activates automatically
when the reverse gear is engaged. A brief confir­
mation tone will sound.

Facility immediately to have the malfunction cor­
rected. The color of the indicator light depends
on the vehicle speed.
A WARNING
-
Driving at higher speeds without the rear
spoiler deployed can impair handling charac­ teristics, making the vehicle harder to con ­
trol.
- Always make sure that the spoiler is de­
ployed when driving at speeds over 85 mph
(140 km/h). If the rear spoiler warning/indi­
cator light in the instrument cluster comes
on, the rear spoiler may not have deployed.
- Never drive at speeds higher than 85 mph
(140 km/h) if the spoiler is not deployed .
Have the spoiler inspected as soon as possi­
ble by an authorized Audi dealer or qualified
workshop.
- Always obey speed limits and other traffic
laws.
A WARNING t =
Improper operation of the rear spoiler can
cause crushing injuries.
-
- Always make sure that nobody, especially
children, is in the way when the rear spoiler
is deployed or retracted.
(D Note
- Never push on the vehicle on the rear spoil­
er. This could cause damage.
- To prevent damage to the rear spoiler do
not lean or place anything on it.
- Only operate the rear spoiler manually when
the luggage compartment lid is close and
the rear spoiler moving parts are not
blocked. Otherwise, damage could occur.
@ Tips
Clean the rear spoiler compartment every 2 to
3 months. To function correctly, the rear
spoiler must be free of ice , snow and leaves.
Intelligent Technology
Energy management
The starting ability is optimized
The energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engtne.
When a vehicle with a conventional energy sys­
tem is not driven for a long time, the vehicle bat­
tery is drained by equipment (for example, the
immobilizer). In certain circumstances , there
could may not be enough energy to start the en­
gine.
Your vehicle is equipped with an intelligent ener­
gy management system for distributing electrici­
ty. This significantly improves the starting ability
and increases the vehicle battery life.
The energy management system Is made up of
battery diagnosis, idling current management
and dynamic energy management.
Battery diagnosis
The battery diagnosis determines the vehicle bat ­
tery charge level. The sensors determine the bat­
tery voltage, the battery current, and the battery
temperature. The current charge level and the
performance of the vehicle battery are deter­
mined based on this.
Idling current management
The idling current management decreases the
energy used while parked. With the engine
switched off , it manages the energy distribution
to the different electrical components. Data from
the battery diagnosis is taken into account for
this.
Depending on the vehicle battery charge level,
electrical equipment is switched off one item af­
ter the other to prevent the vehicle battery from draining and to maintain the starting ability.
Dynamic energy management
While driving , dynamic energy management dis­
tributes the appropriate amount of energy to the
electrical equipment.
It controls the battery
charge level so that the amount of energy is not ..,_

Improperly worn safety belts
0 ,-.. N 0 :i:
;ii
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 pos itioned on the body .
Improper seating positions reduce the effect ive­
ness of safety belts and will even increase the
risk of injury and death by mov ing the safety belt
to crit ica l areas of the body. Imp roper seating
positions also increase the risk of se rious injury
and death when an airbag deploys and strikes an
occupant who is not in the correct seating posi ­
tion . A driver is responsible for the safety of all
ve hicle occupants and especia lly for children.
Therefore:
~ Never permit anyone to assume an incorrect
seated position in the vehicle while traveling

&_ 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 ve hicle occupants
are correctly restrained and stay in a correct
seated position wheneve r the vehicle is be­
i n g used.

Safety belt tensioner
How safety belt pretensioners work
In front, side and rear-end collisions above a
particular severity and in a rollover, safety belts
are tensioned automatically .
Pyrotechnic safety belt pretensioners
The safety belts for the front sea ting posit ions
are equipped with safety belt pretensioners. The
system is act ivated by sensors i n front, side and
rear-end collisions of g rea t seve rity and in a ro ll­
over . This tightens the belt and takes up belt
s lack
Q &. in Service and disposal of safety belt
pretensioner on page 196.
Taking up the s lack
helps to reduce forward occupant movement dur­
ing a collision.
&_ WARNING
-
- It is poss ible for the pretensioners to dep loy
incorrectly.
- The pyrotechnic system can only provide protection for one collision . If the pyrotech­
n ic pretens ioners dep loy, the pre tensioning
system must be replaced.
(0 Tips
The pyrotechn ic safety belt pretensioners can
o nly dep loy once .
- The safety belt pretensioners do not deploy
in minor frontal, side and rear-end coll i­
sions.
- A fine dust is re leased when the pyrotechnic
safety belt pretensioners dep loy. This is no r­
ma l and is not caused by a fi re in the ve hi­

Airbag syste m
& WARNING
A child in a rearward-facing chi ld seat instal­
led on the front passenger seat will be ser i­
ously injured and can be k illed if the front air­
bag inflates -even with an Advanced Airbag
System.
- Although the Advanced A irbag System in
you r vehicle is designed to tu rn off the front
airbag when a rea rwa rd-facing child re­
straint has been insta lled on the fron t pas­
senger seat, nobody can absolutely g uaran ­
tee that deployment is impossible in a ll con ­
ceivable situations that may happen during
the useful life of your vehicle.
- The inflating airbag w ill hit the child seat or
infant carrier w ith great force and will
smash the ch ild seat and child against the
backrest, center armrest, door, or roof.
- Always install rearward-facing ch ild re­
straints on the rear seat.
- If you must install a rearward fac ing ch ild
seat on the front passenger seat because of
exceptional c ircumstances and the
PASSEN­
G ER A IR BAG OFF,;; light does not come
on and stay on, immediately install the rear­
facing child seat in a rea r seating pos ition
and have the a irbag system inspected by
yo ur Audi dealer.
& WARNING
If, i n ex cept ional circumstances, you must i n­
sta ll a forward-facing chi ld restraint on the
front passenger's seat:
- Always make sure the forward-facing se at
has been designed and ce rtified by its man ­
ufacturer for use on a f ront seat with a pas­
senger front and side a irbag .
- Never put the forward -facing child restraint
u p against or very near the instrument pan­
el.
- Always move the front passenger seat to
the highest position in the up and down ad­
justment range and move it back to the
rearmost position in the seat's fore and aft
adjustment range, as fa r away from the air­
bag as possib le, before insta lling the for­
ward-facing child restra int.
204
-
- lways make sure that t he safety belt upper
anchorage is behind the ch ild restraint and
not next to or in front of the child restraint
so that the safety be lt will be p roperly posi­
tioned.
- Always make sure that there is noth ing o n
the front passenge r seat that will cause the
capacitive passenge r detection system in
the seat to signal to the Airbag System tha t
the sea t is occup ied by a perso n when it is
not, or to s ignal th at it is occupie d by some­
one who is heavier than the person ac tually
sitting on the seat . The presence of addi­
tional objects cou ld 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 d if f erent from the way it wou ld
have worked without the object on the seat.
- Make sure that the
PASSENGER AIR BAG
OFF "1; light comes on and stays on all the
time wheneve r the ig nitio n is swi tched on.
Advanced Airbag System components
The fro nt passenge r seat in your veh icle has a lot
of ve ry important parts of the Advanced A irbag
Syste m in it. These parts incl ude the capacitive
passenger detection system, wir ing, b racke ts,
and more . The con trol uni t monitors the system
on the front passenger seat when the ignition is
switched on and turns the airbag indicator light
on when a malfunction in the one of the system
components is detected<=>
page 209. Because
the front passenger seat contains important
parts of the Adva nced A irbag System, you must
take care to p revent it from being damaged.
Damage to the seat may prevent the Advanced
A irbag Sys tem for the front passenge r seat from
do ing its job in a crash .
The front Advanced Airbag System consists
of the following:
-Crash sensors in the front of the veh icle tha t
meas ure vehicle acce le ra tion/dece le ra tion to
prov ide in formation to the Advanced A irbag
System about the sever ity of the crash .
- An elect ronic contro l unit, with integ rated
crash sensors for front and side impacts. The

control 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 for the
driver inside the steering wheel hub.
- An Advanced Airbag with gas generator inside
the instrument panel for the front passenger.
- A capacitive passenger detection system under­
neath the front passenger seat cover. This sys­
tem measures the electrical capacitance of the
person in the seat. The information registered
is sent continuously to the electronic control
unit to regulate deployment of the front Ad­
vanced Airbag on the passenger side.
- An airbag monitoring system and indicator
light
El in the instrument cluster.
- A sensor in each front seat registers the dis­
tance between the respective seat and the
steering wheel or instrument panel. The infor­
mation registered is sent continuously to the
electronic control unit to regulate deployment
of the front Adv a need Airbags.
- The
PASSENGER AIR BAG OFF~; light comes
on and stays on in the headliner¢
page 209,
fig. 163 and tells you when the front Advanced
Airbag on the passenger side has been turned
off.
-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
transm its this information to the electronic
contro l unit.
A WARNING
Damage to the front passenger seat can pre­
vent the front airbag from working properly.
- Improper repair or disassembly of the front
passenger and driver seat will prevent the
Advanced Airbag System from functioning properly.
- Repairs to the front passenger seat must be
performed by qualified and properly trained
workshop personnel.
- Never remove the front passenger or driver
seat from the vehicle.
Airbag system
-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
put them on the seat. The capacitive pas­
senger detection mat in the front passenger
seat will not function properly if it is punc­
tured.
- Never carry things on your lap or carry ob­
jects on the front passenger seat. Such ob­
jects can influence the capacitance regis­
tered by the capacitive passenger detection
system, so that incorrect information is pro­
vided 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 , preventing them and the airbag sys­
tem from working properly.
- Never place seat covers or replacement up­
holstery that have not been specifically ap­
proved by Audi on the front seats.
- Seat covers can prevent the Advanced Air­
bag System from recognizing child re­
straints or occupants on the front passenger
seat and prevent the side airbag in the seat
backrest from deploying properly.
- If a seat heater has been retrofitted or oth­
erwise added to the front passenger seat,
never install any child restraint system on
this seat.
- Never use cushions, pillows, blankets, or
similar items on the front passenger seat.
The additional layers prevent the capacitive
passenger detection system from accurately
measuring the capacitance of the child safe­
ty seat and/or the person on the seat and
thus keep the Advanced Airbag System from
working properly.
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat heater
for child seats) on the front passenger seat
if the device is connected to the 12-volt
socket or the cigarette lighter socket. Such
devices can influence the capacitance regis­
tered by the capacitive passenger detection
205

Airbag syste m
system, so that incorrect information is pro­
vided to the airbag control unit.
- If you must use a child restraint on the front
passenger seat and the child restraint man­
ufacturer's instructions require the use of a
towel, foam cushion or something else to properly position the ch ild restraint, make
certain that the
PASSENGE R AIR BA G OFF
~; light comes on and stays on whenever
the chi ld restraint is installed on the front
passenge r seat.
- If the
PASSENGER AIR BAG OFF~; light
does not come on and stay on, immediate ly
install child restra int in a rea r seating posi­
t ion and have the airbag system inspected
by your Audi dealer.
A WARNING
If the front passenger seat gets wet, dry it im ­
mediately.
- If liquid soaks into the front passenger seat,
this can keep the a irbag system from work­
ing properly and may, for instance, deact i­
vate the passenger frontal airbag. If this
happens, the PA SSENGER AIR BAG OFF ~;
light will come on and stay on together with
the a irbag ind icator light
m in the inst ru­
ment cluster.
- If liquid is pooled on the seat, but has not
soa ked in, this may also keep the airbag sys­
tem from wo rking properly and ca use the
passenger frontal a irbag to be enabled
(turned on), even though there is a properly
installed chi ld restraint system on t he seat.
Wet towe ls or other wet things on the seat
c u shion can have the same effect . If the
front passenger frontal airbag is turned on,
the
PASSENGER AIR BAG OFF~; light light
will go out.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the side
ai rbags s upplement the protection offered by the
front three -po int safety bel ts with p retensioners
and load limiters to he lp reduce the risk of injury
in a wide range of accident and crash situations.
206
Be sure to read the important information about
safety and heed the WARNINGS in this chapter.
Deployment of the Advanced A irbag System and
the ac tiva tion of the sa fe ty belt pretensioners de ­
pend on the dece leration measured by the c rash
sensors and registered by the electronic contro l
u nit . Crash severity depends on speed and decel­
eration as well as the mass and stiffness of the
vehicle or object involved in the crash.
On the passenger side, regard less of safety be lt
use, the front passenger frontal a irbag will be
turned off if the e lectr ica l capacitance measured
by the capacitive passenger detection system on
the front passenger seat is less than the amount
programmed in t he electron ic contro l unit . The
front passenger frontal a irbag w ill also be tur ned
off if the capaci tance measured by the system for
t h e fron t passe nger sea t equals that of a n infan t
of about one year of age in one o f the chi ld sea ts
that was used to certify the Advanced Airbag Sys­
tem under Fe d era l Motor Vehicle Safety Standard
208. The
PASSENGER AIR BAG OFF~; light
comes on and stays on to tell you when the front
Advanced Airbag System on the passenger side has been turned off
c> page 209 .
A WARNING
To reduce the risk of injury when an airbag in­
flates, always wea r safety belts prope rly.
- If you are un restrained, leaning forward, sit­
ting sideways or ou t of position i n any way,
your r is k of injury is much highe r.
- You will also receive ser ious injuries and
could even be killed if yo u ar e u p against the
airbag or too close to i t when it inflates -
eve n with a n Advanced Airb ag
i=>page 197.

Airbag syste m
-Always install rear -facing child seats on the
rear seat.
- If you must install a rearward facing chi ld
seat on the front passenger seat because of
exceptional c ircumstances and the
PA SSEN ­
G ER AIR BAG OFF ~;
light does not come
on and stay on, immediately install the rear­
facing child seat in a rear seating position and have the airbag system inspected by
you r Audi dealer.
_& WARNING
Objects between you and the a irbag w ill in­
crease the risk of in jury in a crash by interfer­
ing with the way the airbag unfo lds or by be­
ing pushed into yo u as the airbag inflates.
-
- Never hold th ings 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 du r­
ing brak ing or other sudden maneuver and
become dangerous projectiles that can
cause serious personal injury if the a irbags
inflate.
- Never place or attach accessor ies or other
objects (such as cup holders, te lephone
brackets, large, heavy or bulky objects) on
the doors, over or near the area marked "AIRBAG" on the steering wheel, instru­
ment pane l, seat backrests or between
those areas and yourself. These objects could cause injury in a crash, espe cially
when the airbags inflate.
- Never recline the front passenge r's seat to
t ransport objects . Items can also move into
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 passenge r seat could cause the capac itive
sensor in t he 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
208
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 t urned 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
wo rked without objects on the seat.
- Always make sure that there is noth ing o n
the front passenge r seat that will cause the
capacitive passenge r de tection system in
the sea t to signal to the Airbag System tha t
the seat is occup ied by a person when it is
not , or to signal that it is occupied by some­
one who is heavier than the person act ually
sitt ing 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 diffe rent from the way it would have
wo rked without the object on the seat.
- Never til t the front passenger seat backrest
forward when the vehicle is mov ing . An in­
flating airbag wi ll force t he bac krest back­
ward and can injure rear seat occup ants .
_& WARNING
The fine dus t created when airbags deploy can
cause breathing prob lems for people with a
h istory of asthma or other breathing condi ­
tions.
- To reduce the r isk of breathing problems,
those with asthma o r other respiratory con­
ditions sho uld get fresh ai r right away by
getting out of the vehicle or opening win ­
dows or doors.
- If you are in a co llision in which airbags de­
ploy, wash your hands and face with m ild
soap and water before eating.
- Be carefu l not to get the dust into your eyes,
or into any cuts or scratches .
-If the residue shou ld get into your eyes,
flush them w ith water .
