tions and cannot warn you before every im­
pending collis ion:
- If the veh icle is too wide for the parking
space and covered by the neighboring
veh icles.
- Approaching objects or peop le such as cy­
clists or skateboarders may not be detected
under certain circumstances.
- The system does not react to stat ionary ob­
jects.
- The v iew of the radar sensors may be im­
pa ired by leaves, snow, heavy spray or dirt .

F ig. 1 33 Example d is play
F ig . 134 In fo ta in me nt system : re ar cro ss -tra ffic ass ist dis­
p lay
The rear cross -traffic assis t can warn the drive r of
a po tential collis ion with approaching cross -traf­
f ic when driv ing i n reverse . Within its limits, the
system monitors the areas beh ind and n ext to
the vehicle using the radar sensors when leaving
a park ing space
c::> page 129, fig. 130. Moving ob­
jec ts tha t are approach ing, such as cars, are de­
tected
c::> fig . 133 .
If the system detects cr itical cross traffic when
ba cking out of a parking space, it will react as fol­
lows :
-Visual indicator : an indicator appea rs in the In­
fotainment system display with a red arrow
symbol. The arrow points in the direction from
which the object is approach ing
c::> fig. 134 .
-Audible warning signal : a continuous tone may
sound as an additional indicator when driving in reverse .
132

tem and cannot prevent a collision by itself.
The drive r must always intervene. The driver
is always responsible for braking at the cor­
rect t ime .
-Please note that the rear cross-traff ic assist
may activate the brakes unexpected ly. Se­
cure any cargo that you are transporting to
reduce the ris k of damage or injury .
-An add itiona l brake activation may be trig­
ge red w ith in 20 seconds after an automatic
brake activation .
-If there is an acoust ic warning signal from
the rea r cross-traffic assist, then the park­
ing system may no t warn you of detected
obs tacles under certain circumstances.

tem p lus/rearv iew camera/peripheral ca meras
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 137.
The
parking system plus assists you when park ­
ing by audibly and visually indicating objects de­
tected
in front of and behind the veh icle
¢ page 137.
The
rearview camera shows the area behind the
vehicle in the Infotainment system display . The
lines in the rearview camera image help you to
park or
maneuver ¢ page 138. The parking sys­
tem plus functions are also available
¢ page 137.
The
peripheral cameras give various views to
help you when parking or maneuvering
¢ page 140. The parking system plus functions
are also available
¢page 137.
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 impa ired as a result.
136
Have an authorized Audi dealer or author­
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 this obstacle.
- Keep enough distance from the curb to re ­
duce the risk of damage to the rims.
{i) 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 143.
- Please refer to the instructions for towing a
trailer located in
¢page 144.
- What appears in the infotainment display is
somewhat time-delayed.
- Th e sensors must be kept clean and free of
snow and ice for the parking aid to operate .
- Th e rearv iew camera is automatically
cleaned when cleaning the rear window*

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, see
c::;,page 354 .
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
ma tion on page 136,
c::;, (D in General information
on page
136!
If the distance to an obstacle remains constant,
the volume of the distance warning gradually lowers after a few seconds until it is muted (this
is not apply in the continuous tone range). If the
obstacle becomes closer than it was before the
sound was muted, the tone will sound again . If
the obstacle is father away than it was before the
sound was muted, no tone w ill sound . Pay atten­
tion to the vehicle's surroundings when you start
to drive.
Activating
The rear parking assist activates automatically
when the reverse gear is engaged. A brief confir­
mat ion tone will sound.
