-Press the sw it c h P111! in t he cen ter console =:> page 170,
fig. 192 to activate the Aud i pa rking system manually.
Activation of the acoustic park ing system is confirmed by
a brief acknowledgement sound. The indicator light in
the switc h lights up.
De activation
-If yo u drive forwa rds faster t han approx. 6 mph (1 0 km/h},
or
-if you switc h the ignition off, the entire acoustic parking
assist is automatically deactivated, or
-you can press the switch P111A. in the center console
=:> page 170, fig. 192 to deact ivate the Audi parking
system. The indicator light in the switch goes out.
You have to turn on the acoustic parking assist manuall y if you wish
to park the vehicle forwards or if you wish to approach an obstacle
forwards and want a distance warning .

Dis tance wa rn ing is given by chimes which are generated by a
signal generator . The volume and the pitch of the chimes can be
adjusted in the MM I
=> page 180.
Mute
I n t he case of vehic les with automatic transmission, an acoustic
distance warning is discontinued when the transmission selector
Controls and equip­ ment lever is moved to the P position
. However, the system remains
active . As soon as the selector lever is moved fro m the
P pos it ion
and the vehicle approaches an obstacle, the acoustic distance
warning resumes.
Dr iving fo rw ard /b ac kw ard
Dista nce warn ing w hen driving fo rward/ backward is based on
detection of an obstac le in the range of the parking assist. As the
distance decreases, t he time interval betwee n the aud ible t ones
becomes shorter.
When the distance is less than approx .
1 ft (0.30 m), the tone
becomes cont inuous. At th is po int you shou ld stop backing up or
driving forward .
I f the distance to an obstacle re m ains the same, the vo lume of the
distance warning is gradua lly reduced after about
4 seconds (does
not app ly to the zone for the continuous tone). If you start to
approach the detected obstacle again, the distance warning will
sound at the norma l volume again.
P arking
When you se lect another gear when park ing (e .g . reverse/forwa rd),
the warning tones are temporarily suppressed, but the visua l
display remains on the MMI display . If you start approaching a
detected obstac le again, the distance warning wi ll sound at the
normal volume again .
Vi su a l displa y
The segments on t he MMI d isp lay indicate a change in the distance
between the vehicle and an obstacle . The number of segments
displayed depends on the obstac les in front of or behind the
vehic le. The c loser the vehic le comes to the obstacle, the closer t he
segments approach the
vehic le => page 170, fig. 193. When the
seg ment before last is d isplaye d, the ve hicle has reac hed the coll i­
sion zone. At this point you should stop backing up or driving
f orward

& WARNING
• Sensors have dead spaces in which objects cannot be
detected. Be especially careful to check for small children and
animals before backing up . Small children and animals will not
always be detected by the sensors.
• The Audi parking system is not a substitute for being careful
and alert when backing up. Be especially careful during parking
and similar maneuvers . Always watch where you are driving and
make sure that nothing is in the way.
• Remember that low obstacles which have already been
signaled may pass below the system's sensing zone when the
vehicle is backing up. The fact that the signal stops does not mean
that you have cleared the obstacle. When the signal stops, impact
is imminent. Objects such as trailer hitches, chains, narrow posts
or fences covered by a thin layer of paint may not always be
detected by the system. They can still damage your vehicle
without warning.
• Always make sure that the volume and frequency of the chimes
is adjusted so that you can easily hear the acoustic distance signal
even if the radio is playing, the air-conditioner blower is on High or
there is a high level of outside noise.
- Check the settings whenever someone else has driven the
vehicle before you.
• Improper reliance on the Audi parking system can cause colli­
sions and serious personal injury.
- Never rely only on parking assist when backing up.
- Always check rear view mirrors to make sure it is safe to back
up.
[ i] Tips

shoulder belt height
The safety belt height adjustors for the front seats can be
used to adjust the height of the shoulder portion of the
safety belt so that it is positioned correctly.
- Push the
latch ~ fig. 229 up or down so that the shoulder
portion of the safety belt is positioned nearly midway
over the
shoulder ~ & in "Safety belt position" on
page 214.
& WARNING
Always read and heed all WARNINGS and other important informa­
tion
~ page 212. •
Improperly worn safety belts
Incorrectly positioned safety belts can cause severe inju­
ries.
Wearing safety belts improperly can cause serious injury or
death. Safety belts can only work when they are correctly positioned on the body. Improper seating
positions reduce
the effectiveness of safety belts and will even increase the
risk of injury and death by moving the safety belt to critical
areas of the body. Improper seating positions also increase
the risk of serious injury and death when an airbag deploys
and strikes an occupant who is not in the correct seating position. A driver is responsible for the safety of all vehicle
occupants and especially for children. Therefore:
- Never permit anyone to assume an incorrect sitting posi­
tion in the vehicle while
traveling ~& .
& WARNING
Improperly worn safety belts increase the risk of serious personal
injury and death whenever a vehicle is being used.
• Always make sure that all vehicle occupants are correctly
restrained and stay in a correct seating position whenever the
vehicle is being used.
• Always read and heed all WARNINGS and other important infor­
mation
~ page 212. •
Safety belt pretensioners
How safety belt pretensioners work
In front, side and rear-end collisions above a particular
severity, safety belts are tensioned automatically.
The safety belts are equipped with safety belt pretensioners . The
system is activated by sensors in front, side and rea r-end collisions
of great severity . This tightens the belt and takes up belt
slack ~ &
in "Service and disposal of safety belt pretensioner" on page 217.
Taking up the slack helps to reduce forward occupan t movement
during a collision.

Airbag system -
--------------=---=--
& WARNING (continued)
• If you must install a rearward facing child seat on the front
passenger seat because of exceptional circumstances and the
PASSENGER AIR BAG OFF light does not come on and stay on,
immediately install the rear-facing child seat in a rear seating posi­
tion and have the airbag system inspected by your Audi dealer.
& WARNING
If, in exceptional circumstances, you must install a forward-facing
child restraint on the front passenger's seat:
• Always make sure the forward-facing seat has been designed
and certified by its manufacturer for use on a front seat with a
passenger front and side airbag.
• Never put the forward-facing child restraint up against or very
near the instrument panel.
• Always move the passenger seat into its rearmost position in
the seat's fore and aft adjustment range, as far away from the
airbag as possible, before installing the forward-facing child
restraint. The backrest must be adjusted to an upright position.
• Make sure that the PASSENGER AIR BAG OFF light comes on
and stays on all the time whenever the ignition is switched on. •
Advanced Airbag System components
The front passenger seat in your vehicle has a lot of very important
parts of the Advanced Airbag System in it. These parts include the
weight -sensing mat, sensors, wiring, brackets, and more. The func ­
tion of the system in the front passenger seat is checked by the elec­
tronic control unit when the ignition is on. The control unit monitors
the Advanced Airbag System and turns the airbag indicator light on
when a malfunction in the system components is detected. The
function of the airbag indicator light is described in greater detail below . Because the front passenger seat contains important parts
Controls and equip­
ment Safety first Vehicle operation
of the Advanced Airbag System, you must
take care to prevent 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 Advanced Airbag System consists of the
following:
• Crash sensors in the front of the vehicle that measure vehicle
acceleration/deceleration 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 control unit "decides" whether to fire the
front airbags based on the information received from the crash
sensors. The control unit also "decides" whether the safety belt
pretensioners should 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 weight -sensing mat under the upholstery padding of the front
passenger seat cushion that measures the total weight on the seat.
The information registered is sent continuously to the electronic
control unit to regulate deployment of the front Advanced Airbag on
the passenger side .
• An airbag monitoring system and indicator light in the instru­
ment
cluster => page 229.
• The PASSENGER AIR BAG OFF light comes on and stays on in the
center of the instrument
panel => page 230, fig. 233 and tells you
when the front Advanced Airbag on the passenger side has been
turned off .
• A sensor below the safety belt latch for the front seat passenger
to measure the tension on the safety belt . The tension on the safety
belt and the weight registered by the weight-sensing mat help the
control unit
"decide" whether the front airbag for the front
passenger seat should be turned off or
not=> page 220, "Child
restraints on the front seat
-some important things to know". .,_
