hitch.
II Audi pre sense: currently restricted

Ass is tan ce sys tems
-If the lanes are narrow or if your are driving on
the edge of your lane. If this is the case, the system may have detected a vehicle in another
lane that is
not adjacent to your current lane.
-If you are driving through a curve . Side assist
may react to a vehicle that is in the same lane
or one lane over from the adjacent lane.
-If side assist reacts to other objects (such as
roadside structures like guard rails).
- In poor weather condit ions . The side assist
funct ions are limited.
Do not cover the radar
sensors ¢ fig. 130 with
stickers, deposits, bicycle wheels or other ob­
jects, because this will impair the function. Do
not use side assist when towing a trailer. For in­
formation on cleaning,
see¢ page 354 .
A WARNING
-Always pay attention to traffic and to the
area around your vehicle. Side assist cannot
replace a dr iver's attention . The driver alone
is a lways responsible for lane changes and
similar d riving maneuvers.
-In some situat ions, the system may not
function or its funct ion may be limited. For
example :
-If vehicles are approach ing or being left
behind very quickly. The display may not
turn on in t ime .
-In poor weather conditions such as heavy
rain, snow or heavy mist.
-On very wide lanes, in tight curves, or if
there is a rise in the road surface. Vehicles in the adjacent lane may not be detected because they are outs ide of the sensor
range .
(D Note
The sensors can be displaced by impacts or
damage to the bumper, whee l housing and
underbody. Th is can impa ir the system. Have
an authorized A udi dealer or authorized Audi
Serv ice Facility check their function .

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.

-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 inaccurate 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.
