Park assist
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.

118 Park ass is t
Vehicles with the parking system are equipped
with a rear view c am era in addition to the
acoustic parking system.
You can choose between two modes to assist
you with park ing. For example, you can use
"parking mode 1" when parking in a parking
space or garage
c:> fig . 128. When you want to
park parallel to the edge of the street, select
"park ing mode 2"
c:> fig. 129.
The rear acoustic park assist system is inte ­
grated in the rear of the vehicle and the rear
view camera is integrated in the rear lid
c:>page 119.
A WARNING
- T he rear view camera has blind spots, in
wh ich objects ca nnot be detected . Be es­
pecially careful to check for small ch il­
dre n and an imals before back ing up .
Small ch ild ren and anima ls w ill not al ­
ways be detected by the sensors .

~ Sen sors in the bumper
Sensors a re loca ted in the rear b umpe rs. If
these detect an obstacle, audible and visual s ignals warn you . The range at which the sen­
sors begin to measure is approx imately:
To the side
2 ft (0 .60 m)
Center rear 5.2 ft (1.60 m)
Distance warn ing when reversing starts whe n
an obstacle is detected in the range of the parking assist system . As the d istance de­
creases, the time interval between the audible
tones becomes shorter.
When the distance is less than 1ft
(0 .30 m),
t h e tone becomes continuous. At t his point
you should stop backing up.
If the distance to an obstacle stays the same,
the volume of the dista nce signal chime is
gradually reduced after about 4 seconds (does
not affect the contin uous signa l tone) . Ap­
proaching another obstacle will cause the d is­
tance signal to sound agai n at the normal vo l­
ume.
R ea r v iew camera coverage area
T he M MI display shows the area covered by
the rear view camera
c:> fig. 130 (D . Objects
that are not in the area covered @are not
shown on the MMI display .
We recommend that you practice parking with
the rear view camera in a traffic-free location
or parking lot to become familiar with the sys­
tem, the or ientation lines, and the ir function.
When doing this, there should be good light and weathe r cond itions.
In the MMI display, objects or vehicles appear
closer or further away if:
- you are driving in reverse gear from a leve l
surface onto an incline , or a downward
slope,
- you are driving in reverse gear toward pro­
trud ing ob jects,
- the vehicle is car ry ing too much load in the
rear.

@ Tips
- The rear view camera picture is avai lable
as soon as the MMI Display or the MMI is
switched on, or the start-up phase is
completed.
- Keep the sensors in the rear bumper and the rear view camera lens clean and free
of snow and ice, so that the parking sys­
tem can work properly . Please follow the
additional notes on
~ page 122.

_& WARNING
-The rear view c amera does not show t he
e ntire area behind t he vehicle
¢ page 118, fig . 130. Watch out espe­
cially for small children and anima ls. The
rear view camera cannot always detect
them, posing risk of an accident!
- Please note that objects not touching the
ground can appear to be further away
than they really a re (for example, the
bumper of a parked vehicle , a trailer
h itch, o r the rear of a truck). In this case,
you shou ld not use the h elp lines to help
wit h pa rking, wh ich poses danger of an
a ccident!
(D Note
- Low obstacles a lready s ignaled by a
wa rning can disappear from th e system's
detec tion range as they are approac hed
and w ill not con tinue to be signaled. Ob­
jec ts such as barr ier chains, tr ailer draw
bars, thin painted vertica l poles or fen ­
ces may not be detecte d by the system,
posing risk of damage.
- In the MMI display, t he direction of trav­
el of the vehicle rear is represented de ­
pending on the steering wheel angle.
The ve hicle fro nt swings out more tha n
the vehicle rear . Maintain plenty of d is­
tance from an obstacle so that your out­ side mirror o r a corner of you r vehicle
does not co llide w it h any obs ta cl es -d an­
ger of ac cident!

122 Park assist
In the MMI display, the direction of travel
of the vehicle rear is represented depend­ing on the steering wheel angle. The vehi­
cle front swings out more than the vehicle
rear. Maintain plenty of distance from an
obstacle so that your outside mirror or a
corner of your vehicle does not collide with
any obstacles -danger of accident!
@ Tips
The left or right orientation lines and sur­
faces will be displayed, depending on the turn signal being used.
