General information
Applies to vehicles: with rea r parking sys te m s/park in g system
p lus/rearview camera
Depending on your vehicle's equipment, various
parking aids will help you when parking and ma­
neuvering.
The
rear parking system is an audible parking aid
that warns you of obstacles
behind the vehicle
¢ page 116.
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 116.
The rearview camera shows the area behind the
vehicle in the MMI display. This display assists
you when you are cross or parallel parking. The
parking system plus functions are also available
¢page 117.
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 a lways
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 - using 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 become impaired as a re­
sult . Have an authorized Audi dealer or au­
thorized Audi Service Facility check their
function.
- Make sure the sensors are not obstructed by
st ickers, deposits or other materials.
If they
are the sensor function could be impaired .

@ 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
- Objects above the sensors such as wall ex­
tensions
- Objects with specific surfaces or struc­
tures such as chain link fences or powder
snow
- If you continue driving closer to a low-lying
object, it may disappear from the sensor
range. Note that you will no longer be
warned about this obstacle.
- The sensors can be displaced by impacts or
damage to the radiator grille, bumper,
wheel housing and the underbody. The park­
ing system may become impaired as a re­
sult. Have an authorized Audi dealer or au­
thorized Audi Service Facility check their
function.
(D Tips
- The 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 for long grass .
- external ultrasonic sources e.g. from
cleaning vehicles.
- heavy rain, snow, or thick vehicle exhaust.
- 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 should be good light and weather
conditions.
- You can change the volume and pitch of the
signals as well as the display¢
page 121 .
-What appears in the MMI display is some­
what time-delayed.
- The sensors must be kept clean and free of
snow and ice for the park assist to operate .

The rear parking system is an audible parking
aid.
Des crip 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, refer to
c:::;,page 235.
The range at which the sensors begin to measure
is approximately:
Side rear 3 ft (0.90
m)
Side 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

Intelligent Technology
is not different from a two wheel drive vehi­
cle. Do not be tempted to accelerate to a
high speed when the road is slippery th is in­
creases the r isk of an accident.
- Note that on wet streets, the front wheels
can "hydrop lane" if driving at speeds that
are too high . Unlike front whee l drive
vehicles, the engi ne does not rev higher sud­
denly when the vehicl e begins hyd rop laning.
Fo r th is r easo n, pay a ttent ion to the road
co ndi tions regardless of your speed.
Energy management
The starting ability is optimized
The en ergy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a ve hicle with a co nventional energy sys­
tem is not driven for a long time, the battery is
drained by equipment (for example the immobil­
izer) . In certa in circumstances , there cou ld may
not be eno ugh energy to start the engine .
Your vehicle is equipped w it h an intelligent ener­
gy management system for distr ibut ing electric i­
ty . T his sign ificantly improves the starting ability
and inc reases the battery life .
The energy management system Is made up of
battery diagnos is , idling cu rrent management
and dynamic energy management.
Battery diagnosis
The batte ry diagnosis determines the batte ry
charge leve l. The sensors determine the batte ry
voltage, the battery current , and the battery
t emperature . The current cha rge level and the
pe rformance of t he battery a re dete rmined based
on this .
Idling current management
The idling cu rrent management decreases the
energy used while parked. W it h the engine
sw itched off, it manages the energy d istribution
to the different electrical components . Date from
battery diagnosis is taken into account for this .
128
Depend ing on the ba tte ry charge leve l, electrical
equipment is switched off one item after the oth­
er, to prevent the battery from dra ining and to
retain the start ing ability.
Dynamic energy management
While driv ing, dynam ic ene rgy management dis­
tribu tes the appropriate amount o f energy to the
e lectrica l equ ipment. It control s the battery
charge level so that more ene rgy is not used then
i s be ing generated in order to maintain an opti­
mal battery charge level.
(D Tips
'
- Energy management cannot overcome the
laws of p hys ics. Note that the charge level
and length of the battery life a re limited.
- When the sta rting ability is endangered, the
(•) indicator light t urns on
c:> page 19 .
What you should know
Maintaining the starting ability is the highest
priority.
A lot of st ress is placed on the battery when dr iv ­
ing sho rt distances, in traffic, and at cold t imes
of the year. A lot of energy is used but little is
generated.
It is also critical when the engine is
not ru nning but e lectr ica l equipment is sw itched
o n. In th is case, energy is used but none is gener ­
ated.
In sit uat ions like this, e nergy ma nagement w ill
active ly regu lated the distribution of energy .
Long periods without use
If you do not drive your vehicle for several days or
weeks, e lectr ica l cons umers are grad ually scaled
back or sw itched off. This reduces energy use and
ensures the ve hicle w ill be able to start after long
per iods of time . Some conven ience functions
suc h as opening w it h the remote co ntrol key may
not be available. These conve nience f unct ions
will be ava ila ble aga in once you swi tch the igni-
tion on and st art the eng ine . .,_

Safety belts

sition of the safety belts.
Improperly worn safety belts
Incorrectly positioned safety belts con cause se­ vere injuries.
Wearing safety be lts imprope rly can cause seri­
ous injury or death . Safety belts can on ly work
when they are correctly positioned on the body.
Improper seating positions reduce the effective­
ness of safety be lts and will
even i ncrease the risk
146
of injury and death by moving the safety belt to
critical areas of the body . Improper seating posi­
tions also increase the risk of serious in jury and
death when an airbag deploys and strikes an oc­
cupant who is not in the correct seating position.
A driver is responsible for the safety of all vehicle
occupants and especially for ch ildren . Therefore:
... Never permit anyone to assume an incorrect sit-
ting posit ion in the vehicle while traveling
¢ &_ .
A WARNING
Improperly worn safety belts increase the r isk
of serious personal inju ry and death wheneve r
a veh icle is being used.
- Always make sure that all vehi cle occupants
are correctly restrained and stay in a correct
seating position wheneve r the vehicle is be­
ing used .
- Always read and heed a ll WARNINGS and
o ther important informa tion

Belt tensioners
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.
R ev ersib le safety belt t ensione rs
The safety belts on the front seats are equipped
with power reversib le tensioners. The fo llow ing
functions are availab le when the driver's/front
passenger's safety belts are fastened:
- Automatic tensio ners: at the start of a drive,
the safety belts automat ica lly adjust to the
passenger after a certain t ime period or vehicle
speed.
- In certain driving situations, the safety belts
may tighten with a reversible tensioning func­
tion
¢page 103.
-The safety belts may a lso tighten with this re-
vers ible tensioning function in minor collisions.

A WARNING
A child in a rearward-facing child seat instal ­
led on the front passenger seat wi ll be seri ­
ously injured and can be killed if the front air­
bag inflates -even with an Advanced Airbag
System.
-Although the Advanced Airbag System in
your vehicle is designed to turn off the front
airbag when a rearward-facing child re­
straint has been installed on the front pas­ senger seat, nobody can absolutely guaran­
tee that deployment is impossible in all con­
c eivable s ituations that may happen dur ing
the useful life o f you r vehicle.
- The inflating a irbag w ill hit the child seat or
infant carrier w ith great force an d will
smash the ch ild seat and child agains t the
backrest, center armrest, doo r, or roo f.
- Alw ays install rearward- facing child re­
straints on the rear seat .
- If you must i nst all a rearw ard facing child
sea t on the front passenger sea t beca use of
excep tional circ umstances and the
PASSEN­
GER 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 a irbag system inspected by
your Audi dealer.
A WARNING
If, in exceptional c ircumstances, you must in­
stall a forward-facing ch ild restraint on the
front passenge r's seat:
-Always make sure the forward-fac ing seat
has be en designed and certified by its man­
ufact urer for use on a fro nt seat wit h a pas­
senger front and side airbag.
- Never put the forwa rd-facing child rest raint
up against or ve ry nea r the i nstr ument pan ­
el.
-Always move t he passenger seat into its
rearmost position in the seat 's fore and aft
adjus tment range, as far away from the air ­
bag as possib le, before installing the fo r­
ward-facing c hild restraint . The backrest
must be adjusted to an up right position .
-
Airbag syste m
- Always make sure that there is nothing on
the front passenger seat that w ill cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that
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 actually
sitt ing on the se at. T he presen ce of add i­
tion al ob jects could cause t he passenger
front airbag to be tu rned on when it shou ld
be off, or co uld cause the ai rbag to wo rk in a
way that is different from the way it would
have worked without the ob ject on the seat.
- Make sure that the
PASSENGER AIR BAG
OF F light comes on and stays on all the time
wheneve r the ignit ion is switched on.
Advanced Airbag System components
The front passenger seat in yo ur vehicle has a lot
of very impo rtant parts of the Advanced A irbag
System in it . T hese pa rts include the capacitive
passenge r detection system, wir ing, brackets,
and more. The con trol unit mon itors the syste m
o n the front passenge r se at when the ig nition is
swi tched on and turns the airbag indicator ligh t
on when a malfunction in the one of the system
components is detected
¢ page 160 . Because
the front passenger seat contains important
parts of the Advanced A irbag System, yo u m ust
take care to prevent it from being damaged.
Damage to the seat may prevent the Advanced
Airbag System for the front passenger seat from
doing its job in a crash.
The front Advanced Airbag System consi sts
of the following:
- Crash sensors in the front of the vehicle that
measure vehicle acceleration/deceleration to
p rov ide i nfo rmat ion to the Advanced Airbag
System abo ut the sever ity o f the cr ash.
- An elect ron ic cont ro l unit, with integrated
cr ash senso rs for front and s ide imp acts. The
cont ro l uni t "dec ides" whet her to fire the fron t
airbags based on the info rmation received from
the crash sensors . The control unit a lso "de ­
cides" whether the safety belt pretens ione rs
should be activated. ..,.

Airbag syste m
-An Advanced Airbag wi th gas generator for the
driver inside the steering wheel hub.
- An Advanced Airbag with gas generator inside
the instrument pane l for the front passenger.
- A capacitive passenger dete ct ion system under­
neath the front passenge r seat cover. This sys ­
tem measures the e lectrical 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 s ide.
- An airbag monitoring system and indicator
light in the instrument cluster¢
page 160.
-A sensor in each front seat registers the dis­
tance between the respect ive seat and the
steering wheel or instrument panel. The infor­
mation registered is sent cont inuously to the
electronic control unit to regulate deployment
of the front Advanced Airbags.
- The
PASSENGER AIR BAG OFF light comes on
and stays on in the center of the instrument
pane l¢
page 198 a nd tells you when the front
Advanced Airbag on the passenger side has been t urned off .
- A sensor in the safety belt latch for the dr iver
and for the front seat passenger that senses
whether that safety belt is latched or not and
transmits this information to the e lectronic
control unit .
_&. WARNING
Damage to the front passenger seat can pre­
vent the front airbag from work ing properly.
- Improper repair or disassembly of the front
passenger and driver seat w ill prevent the
Advanced Airbag System from funct ioning
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 veh icle.
- Never remove the upholstery from the front
passenger seat.
- Never disassemble or remove parts from the
seat or disconnect wires from it.
156
- Never carry sharp objects in yo ur poc kets 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 you r lap or carry ob­
jects on the front passenger seat. Such ob­
jects can influence the capacitance regis­
tered by the capac itive passenger detection
sy stem, so that in correct info rmation is pro­
vided to the airbag cont rol uni t.
- Never store items under the front passenger
se at. P arts of the Advanced Airbag System
under the passenger seat could be dam­
aged, p reventing t hem and the airbag sys­
tem from wo rking properly.
- Never p lace sea t covers or rep lacement 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 c hild re­
straints or occupants on the front passenger
seat and prevent the side a irbag in the seat
backrest from deploying properly.
- If a seat heater has been retrofitted or oth­
erw ise added to the front passenger seat,
never install any child restraint system on
this seat.
- Never use cushions, pillows, b lankets, or
sim ila r 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 Adv ance d Airbag System from
wo rking properly .
- Never p lace or u se any e lectr ic al device
(s uc h a s a laptop, CD player, elec tronic
games device, power inve rter 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 soc ket. Such
dev ices can influence the capac itance regis­
tered by the capac itive passe nger detection
system, so that incorrect info rmation is pro-
vided to the ai rbag cont rol unit.

and have the airbag system inspected by
yo ur Audi dealer .
&_ WARNING
If the front passenger seat gets wet, dry it im­
mediately.
-If liquid soaks into the front passenger seat,
this can keep the airbag system from work­ ing properly and may, for instance, deacti­
vate the passenger frontal a irbag. If th is
happens, the
PASSENGER AIR BAG OFF
light will come on and stay on together with
the a irbag indicator light
II in the inst ru­
me nt cluster.
- If liquid is poo led on the seat, but has not
soa ked in, this may a lso keep the airbag sys­
tem from wor king proper ly and cause the
passenger fron tal ai rbag to be ena bled
(turned on), even tho ugh there is a properly
installed chi ld restraint system on the seat .
Wet towels or other wet things on the seat c u shion can have the same effect. If the
front passenger fronta l airbag is turned on,
the
PASSENGER AIR BAG OFF light will go
