2020 AUDI A4 brake sensor

8W1012721BB
Parking and maneuvering

Requirements
— The parking aid is switched on > page 147 or
reverse gear is selected.
— The speed when driving in reverse must not be
higher than approximately 9 mph (15 km/h).
Displays, warnings, and braking
— Display: the display @ appears only when the
parking aid is active. For vehicles with peripher-
al cameras, this only happens in the Rear and
Rear corner camera views. Arrows show the di-
rection from which the cross traffic is approach-
ing.
— Audible warnings: a continuous tone may
sound as an additional warning when driving in
reverse.
— Automatic brake activation: if you do not react
to a warning, a brief braking by the system can
warn you of a potential collision with an ap-
proaching object.
The audible warning signal and the automatic
brake activation occur only when driving in re-
verse.
Switching on and off
— Applies to MMI: Select on the home screen: VE-
HICLE > Parking aid > Rear cross-traffic assist.
Or:
— When the parking aid active, select L--| > Rear
cross-traffic assist in the center display.


Messages
if or » is displayed when there is a
malfunction, the rear cross traffic assist func-
tions may be unavailable or may be limited.

A message that indicates the cause and possible
solution may appear with some displays. The
weather conditions may be too poor or a sensor
may be covered. Clean the sensor area in the ve-
hicle rear and try to turn the systems on again
later.
If the malfunction remains, drive to an author-
ized Audi dealer or authorized Audi Service Facili-
ty immediately to have the malfunction correct-
ed.

ZA WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.
—The rear cross-traffic assist will not provide
alerts about people and cannot warn you
about every type of approaching objects,
such as cyclists. Always monitor the traffic
as well as the vehicle's surroundings with di-
rect eye contact.
— The system may not react if objects are ap-
proaching very quickly.
—The rear cross-traffic assist will not provide
alerts if your vehicle is parallel or diagonally
parked or if your vehicle is pulled too far in-
to the parking space so that it is hidden by
adjacent vehicles.
@) Tips
— Once an automatic brake activation occurs,
the system cannot initiate another activa-
tion for several seconds.
— System functions may not be available if the
ESC is limited or switched off, or if there is a
malfunction.

—If there is an audio warning signal from the
rear cross-traffic assist, then the parking aid
may not be able to provide audio warnings
about detected obstacles under certain cir-
cumstances.
— For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regulations, see
=> page 275.
— The coverage areas of the sensors > fig. 133
are diagrams and do not represent a true-
to-scale image of the sensor ranges.
Assisted parking
General information
Applies to: vehicles with park assist
If your vehicle is equipped with park assist, this
system helps you find suitable parking spaces.
Parking spaces are measured using ultrasonic
sensors on the sides of the vehicle.

Parking and maneuvering

If the parking space allows different parking op-
tions, they can be selected manually. Press one of
the suggested parking options @ in the center
display.
Starting the parking process
As soon as the vehicle has reached the correct po-
sition, a P will appear in the center display above
the selected parking space (). The roof in the
parking aid display @) may show the required
braking or driving direction.
> Keep the vehicle as parallel as possible to the
parked vehicles or to the side of the road.
> Make sure that the parking space is suitable for
your vehicle >@.
Start parking using the park assist > page 156.
Maneuvering area
The vehicle can go off course during the parking
process > A\. If there are obstacles within the
maneuvering area that block or endanger the
parking process, for example on the opposite
side of the street, a message may appear. You
may need to drive farther forward and stay closer
to the row of parking spaces.

Z\ WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.
— The driver is always responsible when enter-
ing or exiting a parking space and during
similar maneuvers.
— Sensors and cameras have spots in which
the surrounding area cannot be detected.
Objects, animals, and people may only be
detected with limitations may not be detect-
ed at all. Always monitor the traffic and the
vehicle's surroundings directly and do not

become distracted.

@) Note
— Parking spaces classified as suitable by the
system may have been detected incorrectly.
The driver must decide if the parking space
displayed is suitable for the vehicle.
— Certain conditions near the parking space
may cause the parking process to fail, such
as if the parking space is near trees or posts,
or if the ground is covered, for example,
with gravel, snow, or ice.
G) Tips
— If you did not drive past a suitable parking
space too quickly, the system can also be ac-
tivated afterward by pressing Pe.
— The Electronic Stabilization Control (ESC)
must not be switched off during the parking
process. If the ESC intervenes, the parking
process will be canceled.
— You can also drive into a perpendicular park-
ing space yourself and then activate the sys-
tem. If this is the case, the front of the vehi-
cle should already be in the space @)
=> page 154, fig. 135 so that the sensors
can measure the space.
— The system is not available when certain as-
sist systems are switched on.
—If there are suitable parking spaces on both
sides of the street, for example on a one-
way street, you can change the side where
the system is searching for parking spaces
by activating the turn signal for the other
side or by pressing on that side in the center
display.
— The park systems do not provide support for
assisted parking on tight curves.
Park assist
General information
Applies to: vehicles with park assist
The park assist helps you when parking and exit-
ing parking spaces after the parking space
search. The park assist takes over the steering of
the vehicle while the driver accelerates, brakes,
and monitors the vehicle's surroundings. Park as-
sist can be interrupted at any time.

ZA WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.

Care and cleaning


—To reduce the risk of cuts, protect yourself
from sharp metal components when wash-
ing the underbody or the inside of the wheel
housings.
— After washing the vehicle, the braking effect
may be delayed due to moisture on the
brake rotors or ice in the winter. This in-
creases the risk of an accident. The brakes
must be dried with a few careful brake appli-
cations.

@) Note
— If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
Power folding exterior mirrors* must only
be folded in and out using the power folding
function.
—To reduce the risk of damage to the rims
and tires, compare the width between the
wheels on your vehicle with the distance be-
tween the guide rails in the car wash.
—To reduce the risk of damage, compare the
height and width of your vehicle with the
height and width of the inside of the car
wash.
—To reduce the risk of paint damage, do not
wash the vehicle in direct sunlight.
—To reduce the risk of damage, do not wash
decorative decals* with a pressure washer.
—To reduce the risk of damage to the surface,
do not use insect removing sponges, kitchen
sponges, or similar items.
— When washing matte finish painted vehicle
components:
—To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax.
— Never use protective wax. It can destroy
the matte finish effect.
— Do not place any stickers or magnetic
signs on vehicle components painted with
matte finish paint. The paint could be
damaged when the stickers or magnets
are removed.
(*) For the sake of the environment
Only wash the vehicle in facilities specially de-
signed for that purpose. This will reduce the
risk of dirty water contaminated with oil from
entering the sewer system.

components, refer to the following tables. The
information contained there is simply recommen-
dations. For questions or for components that
