Parking system
Applies to vehicles: with pa rking system
Different park assist systems may be used for
parking or maneuvering, depending on the
vehicle's features.
Parking system (rear)*:
For the parking system (rear), the acoustic
park assist system is installed in the rear of
the vehicle
¢ page 116.
The rear parking assist system uses ultrason ic
sensors to determine the distance of the vehi
cle from a detected obstacle. There are a total
of four sensors located on the rear bumper
(two in the middle and two on the sides).
Parking system (rear, with rear view
camera)*:
For the parking system (rear, with rear view
camera),
the rear acoustic park assist system
is integrated in the rear of the vehicle and the
rear view camera is integrated in the rear lid
¢page 119.
The parking system (rear, with rear view cam
era)
uses ultrasonic sensors to determine the
distance of the vehicle from a detected obsta
cle . There are a total of four sensors located
on the rear bumper (two in the middle and
two on the sides).
Parking system (rear)
Rear acoustic park assist
App lies to vehicles: with parking system (rear)
The rear acoustic park assist warns you of ob
stacles or objects behind your car.
Description
The rear acoustic parking ass ist system deter
mines the distance of the vehicle from an ob
stacle using ultrasonic sensors. There are 4
sensors in the rear bumper.
The range at which the senso rs start to meas
ure is
about :
To the side 2 ft (0.60 m)
Center rear 5.2 ft (1.60 m)
Activation
Acoustic parking assist is activated automati
ca lly when
reverse gear is engaged. A brief
tone confirms that the system is activated.
Warning tones
Distance warning is given by warn ing tones
which are generated by the rear signal genera
tor. The volume and the pitch of the warning
tones can be adjusted in the MMI*
¢page 117.
Reversing
Distance warning when reversing starts when
an obstacle is detected in the range of the
parking assist system . As the distance de
creases, the time interval between the audible
tones becomes shorter.
When the distance is less than 1ft (0.30 m),
the tone becomes continuous. At this point
you should stop backing up .
Please note that low objects already signalled
by a warning can disappear from the system's
detection range and will not continue to be
signalled .
If the distance to an obstacle remains the
same, the volume of the distance warning is
gradua lly reduced after about 4 seconds (this
does not apply in the continous tone range).
Approaching another obstacle will resu lt in
the distance warning sounding at the normal
volume again.
Malfunctions in the system
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
system can function properly.

_& WARNING
-Sensors have dead spaces in which ob
jects cannot be detected. Be especially
alert for small children and animals,
since they are not always detected by the
sensors.
- The acoustic park ing system is not a sub
st itute for the driver 's own caut ion and
alertness. U ltimate responsibi lity always
remains with the driver during parking
and simi lar maneuvers . Always watch
where you are driving.
- You should always adjust the vo lume and
frequency of the warning tones so that
yo u can easily hear the acoustic distance
warning even if the radio is p laying, the
air-cond itioner blower is on High or there
is a high level of outside noise .
- Check the settings whenever anyone else has driven the vehicle before you.
(D Note
-Remember that low obstacles for wh ich
a warn ing has already been iss ued may
"dive" below the system's sensing zone if
the veh icle is being backed up closer. In
th is case, the warn ing sound shutting off
does
not i ndicate that you have cleared
the obstacle . Instead, impact is immi
nent.
- Objects such as trailer hitches, chains,
narrow posts or fences covered by a th in
l ayer of paint may not always be detect
ed by the system. They can still damage
your vehicle without warning.
@ Tips
Keep the sensors in the rear bumper clean
and free of snow and ice so that the acous
tic parking assist system can function
properly.

Advanced Airbag System components
The fron t passenger sea t in your vehicle h as a
lot of very important par ts of the Advanced
Airbag System in it. These parts include t he
weight -sensing mat, sensors, wiring, brack
ets, and more. The function of the system in
the front passenger seat is checked by the
e lectronic control un it when the ignit ion is on.
The control unit mon itors the Advanced Air
bag System and turns the airbag indicator
l ight on when a ma lfunction in t he system
components is detected. The func tion of the
a ir bag ind icator light is described in greater
detai l be low . Because the front passenger
seat contains important parts of the Ad
vanced A irbag System, you m ust take care to
prevent it from be ing damaged. Damage to
the seat may prevent the Advanced Airbag for
the front passenger seat from doing its job in
a crash .
The front Advanced Airb ag Sy stem
consists of the following:
- Crash sensors in the front of the veh icle that
measure veh icle acceleration/deceleration
to provide information to the Advanced Air
bag System abou t the seve rity of the crash.
- An electron ic co ntrol unit, with integ rated
crash sensors for front and side impacts .
T he cont ro l unit "dec ides " w het her to fire
the front airbags based on the information
received from the crash senso rs . The contro l
unit a lso "decides" whethe r the safety be lt
pretensioners should be activated . -
An Advanced A irbag w ith gas generator and
cont ro l valve for the d river inside the steer
ing wheel h ub.
- An Advanced A irbag with gas ge nerator and
contro l valve inside the instrument pane l for
the front passenger.
- A weight-sensing mat under the up ho lstery
pad ding of the front passenger seat cushion
that measures the total weight on the seat.
The informat ion registered is sent continu
ously to the electronic contro l unit to regu
late deployment of the front Advanced Air bag on the passenger side .
- An airbag monitor ing system and i ndicator
light in the i nstr ument cluster ~
page 156 .
-A sensor in each front seat registers the dis
tance between the respective seat a nd the
steer ing whee l o r i ns trument panel. The i n
formation registered is sent cont inuously to
t he ele ctr onic cont ro l uni t to regula te de
p loyment o f the front Advance d Airbags .
- The
PASSENGER AIR BAG OFF ligh t comes
on and st ays on in the cen ter o f the instr u
ment panel
~ page 156, fig . 156 and tells
you whe n the front Advanced Airbag on the
passenger side has been tu rned off .
- A sensor below the safety be lt latch for the
front seat passenger to measure the tension on the safety be lt . The tension on the safety
be lt and the weight registered by the
weight-sensing mat he lp the control unit

A WARNING
Damage to the front passenger seat can
p revent the front airbag from work ing
properly.
-
Page 155 of 302

-Improper repair or disassembly of the
front passenger and driver seat will pre
vent 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 .
- 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 weight
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-sensing mat and send the
wrong information to the airbag control
unit.
- Never store items under the front pas
senger seat. Parts of the Advanced Air
bag System under the passenger seat
could be damaged, preventing them and
the airbag system from working proper
ly.
- Never place seat covers or replacement
upholstery that have not been specifical
ly approved by Audi on the front seats.
- Seat covers can prevent the Advanced
Airbag System from recognizing child re
straints or occupants on the front pas
senger seat and prevent the side airbag in the seat backrest from deploying prop
erly.
- Never use cushions, pillows, blankets or
similar items on the front passenger
seat . The additional padding will prevent
the weight-sensing mat in the seat from
accurately registering the child restraint
or person on the seat and prevent the
Advanced Airbag System from function
ing properly.
- If you must use a child restraint on the
front passenger seat and the child re-
Airbag system 153
straint manufacturer's instructions re
quire the use of a towel, foam cushion or
something else to properly position the
child restraint, make certain that the
PASSENGER AIR BAG OFF light comes
on and stays on whenever the child re
straint is installed on the front passen
ger seat.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi
ately install child restraint in a rear seat
ing position and have the airbag system
inspected by your authorized Audi dealer .
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
side airbags supplement the protection of
fered by the front three-point safety belts
with pretensioners and load limiters and the
adjustable head restraints to help reduce the
risk of injury in a wide range of accident and
crash situations. Be sure to read the impor
tant information about safety and heed the
WARNINGS in this chapter.
Deployment of the Adv a need Airbag System
and the activation of the safety belt preten
sioners depend on the deceleration measured
by the crash sensors and registered by the
electronic control unit. The amount of infla
tion of the front airbags can also be adapted
to the front sea t position, depending on the
distance between the respective front seat
and the steering wheel or instrument panel as registered by sensors in the seats . Crash se
verity depends on speed and deceleration as
well as the mass and stiffness of the vehicle
or object involved in the crash.
On the passenger side, regardless of safety
belt use, the airbag will be turned off if the
weight on the passenger seat is less than the
amount programmed in the electronic control
unit. The front airbag on the passenger side
will also be turned off if one of the child safe-
ty seats that has been certified under Federal
Motor Vehicle Safety Standard 208 has been
recogni zed on the seat . The
