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.

The rearview camera is located above the rear li­
cense plate bracket. Mak e sure that the lens for
the rearview camera
c::> fig. 124 is not covered by
deposits or any other obstructions because this
can impair the function of the rearview camera .
For information on cleaning, refer to
c::> page 337 .
The rearview camera coverage area includes (D
c::> fig. 123. Only this a rea is shown in the Info­
tainment display . Objects that are outside of this
area @are not displayed.
A WARNING
-Always read and follow the applicable warn­
ings
c::> .&. in General information on
page 124.
- If the position and the installation angle of
the rearview camera was changed, for ex­
ample after a collision, do not continue to
use the system for safety reasons. Have it
checked by an authorized Audi dealer or au­
thorized Audi Service Facility.
- Only use the rearview camera to assist you if
it shows a good, clear picture. For example,
the image may be affected by the sun shin­
ing into the lens, dirt on the lens or if there
is a malfunction.
- Use the rearview camera only if the luggage
compartment lid is completely closed. Make
sure any objects you may have mounted on
the luggage compartment lid do not block
the rearview camera .
- The camera lens enlarges and distorts the field of vision . The object appears both al­
tered and inexact on the screen .
- In certain situations , people or objects in
the display appear closer or farther away:
- For objects that do not touch the ground,
such as the bumper of a parked vehicle, a
trailer hitch or the rear of a truck. Do not use the orientation lines in this case.
- If driven from a level surface onto an in­
cline, or a downward slope.
- If driven toward protruding objects.
- If the vehicle is carrying too much load in
the rear.
Parking systems
(D Note
-Always read and follow the applicable warn­
ings
c::> (D in General information on

- The orange colored orientation lines in the
Infotainment display show the vehicle path
based on the steering wheel angle. The
front of the vehicle swings out more than
the rear of the vehicle . Maintain plenty of
distance so that an exterior mirror or a cor­
ner of the vehicle does not collide with any
obstacles.

plus maximum load . The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seat ing capaci­
ty") with an assumed weight of
150 lbs (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any luggage in the vehicle. If you tow
a trailer , the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load .
The
Gross Axle Weight Rating
(" GAWR") is the maximum load
that can be applied at each of the
vehicle 's two axles.
The fact that there is an upper limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited . The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as
luggage.
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating
330
are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar
~ page 327,
fig . 255 .
& WARNING ~ -
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to
carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance .
-Tires on a vehicle that has been overloaded can fail sud ­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash .
-Always make sure that the to­ tal load being transported -
including the weight of a trail­
er hitch and the tongue
weight of a loaded trailer - does not make the vehicle
heavier than the vehicle 's
Gross Vehicle Weight Rating.
