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 125.
Parking system plus assists you when parking by
using audio and visual signals to indicate objects
detected in
front of and behind the vehicle
¢ page 125.
The rearview camera shows the area behind the
vehicle in the Infotainment display . The lines in
the rearview camera image help you to park or
maneuver ¢
page 126. The parking system plus
functions are also available
¢page 125.
The peripheral cameras give various views to
help you when parking or maneuvering
¢ page 128 . fhe parking system plus functions
are also available
¢ page 125.
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 always
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 keep your eyes on the vehicle's sur­
roundings, using the rearview mirror as
well .
- The sensors can be displaced by impacts or
damage to the radiator grille, bumper,
wheel housing and the underbody . The park­
ing system may be impaired as a result.
Have an authorized Audi dealer or author-
124
ized Audi Service Facility check their func­
tion .
(D 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 certain surfaces or structures
such as chain link fences or powder snow
- If you continue driving closer to a low ob­
ject, it may disappear from the sensor range. Note that you will no longer be
warned about th is obstacle .
- Keep enough distance from the curb to
avoid damage to the rims.
(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 when there is tall
grass.
- external ultrasonic sources such as from
cleaning vehicles .
- in heavy rain, snow, or thick vehicle ex­
haust.
- 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 weath­
er conditions.
- You can change the volume of the signals
and the display ¢
page 131.
-Please refer to the instructions for trailer
towing in
¢page 132.
- What appears in the infotainment display is
somewhat time-delayed.
- Th e sensors must be kept clean and free of
snow and ice for park assist to operate.

Rear parking system
Description
Applies to: vehicles with rear parking system
The rear parking system is an audible parking
aid .
Descr iption
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 function of the system . For informa­
tion on cleaning, refer to
c:> page 337.
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 124,

If the distance to an obstacle remains constant,
the volume of the distance warning lowers down
to mute after a few seconds (this does not apply
in the continuous tone range). If the obstacle
comes closer before the system mutes, the tone
sounds again. If the obstacle moves farther away
before the system mutes, a tone will not sound.
Pay attention to the vehicle's surround ings when
you start to drive.
Activating
The rear parking assist activates automatically
when the reverse gear is engaged. You will hear a
brief confirmation tone.

With the front seats, the height adjustment
of the seat can also be used to adjust the po­
sition of the safety belts.
Improperly worn safety belts
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
n ess of safety be lts and will even inc rease the
ris k of injury and death by mov ing the safety bel t
to cr it ica l areas of the body. Imp roper seating
positions also increase the risk of serious inj ury
and death when an airbag deploys and strikes an
occ upant who is not in the co rrect seat ing posi­
tion. A driver is respons ible for the safety of all
vehicle occupants and espec ia lly for children.
Therefore:
.. Never permit anyone to ass ume an incorrect
s itting position in the veh icle wh ile traveling
¢ &, .
A WARNING
Improperly worn safety belts i ncrease the risk
of serious personal injury and death wheneve r
a vehicle is be ing used.
S afet y be lts
- Always make sure that all veh icle occupants
are correctly restrained and stay in a correct
seating position whenever the vehicle is be­
ing used.
- Always read and heed all WARNINGS and
other important informat ion¢

-The s afe ty be lts may also tighten with thi s re-
versible tens ion ing f unct ion in m inor collisions.
Pyrotechnic safety belt pretens ioners
All safety belts except for the safety belt in the
center seat position of the rea r seat are equipped
with safety belt pretensioners. The sys tem is acti­
va ted by sensors in front, side and rear-end co lli­
s ions of great severity and in a rollover. Th is
t ightens the belt and takes up belt slack¢&.
in
Service and disposal of safety belt pretensioner
on page 252.
Taking up the slack helps to re­
duce forward occupant movement during a co lli­
s io n.
(!) Tips
The pyrotechn ic safety belt pretensioners can
on ly be act ivated once.
- The safety belt pretensione rs do not deploy
in minor frontal, side and rear-end colli­
sions.
- When the pyrotechn ic safety belt preten­
sioners are activated, a fine dust is released.
Th is is normal and is not caused by a fire in
the vehicle .
- The relevant safety requirements must be
observed when the vehicle or components
of the sys tem are scrapped. An authorized

The f ront Ad vanc ed Airb ag Sy stem con sist s
of the following:
- Crash sensors in the front of the vehicle that
measu re vehicle accelerat ion/ decelerat ion to
provide information to the Advanced Airbag
System about the severity of the crash.
- An electronic cont rol unit, with integrated
c rash 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 contro l unit also "de­
cides" whether the safety be lt pretensioners
should be activated .
- An Advanced Airbag with gas generator and
contro l valve for the driver ins ide the steer ing
wheel hub.
- An Advanced Airbag with gas generator and
contro l valve inside the instrument panel for
the front passenger.
- A capac itive passenger detect ion system under­
neath the front passenger seat cover. This sys­
tem measures the electrical capac itance of the
person in the seat . The information registered
