2021 AUDI A4 brake sensor

Parking and maneuvering

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.
@) Tips
— Ifyou did not drive past a suitable parking
space too quickly, the parking space search
can also be activated 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 157, fig. 131 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
ere eure)
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
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 117.
— The driver is always responsible when enter-
ing or exiting a parking space and during
similar maneuvers.
— Do not use this function if the vehicle cannot
move freely, for example when on a vehicle
jack.
— 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
— Do not use the park assist systems when
transporting cargo that extends out of the
vehicle, when snow chains are mounted, or
when the parking space is on a hill or in-
cline.
— Park assist guides the vehicle either away
from curbs or onto them if other vehicles
are parked on the curb. Make sure that your
vehicle's tires and rims are not damaged.
Resume control of the vehicle in time or
stop the parking process if needed to pre-
vent damage.
G) Tips
Follow the legal regulations in the country
where you are located when using Park assist.
Parking with the park assists
Applies to: vehicles with park assist
Requirement: a suitable parking space must be
found and selected > page 157. The vehicle must
initially be stationary.
In the center display, arrows and symbols on the
vehicle roof 2) > page 158, fig. 133 indicate
what action is needed, such as applying the

Parking and maneuvering

brakes or changing the direction. Park assist au-
tomatically steers the vehicle into the parking
space while the driver presses the pedals.
>» After stopping the vehicle briefly, make sure
the actual direction the vehicle is traveling
matches the direction indicated by the park as-
sist.
> Remove your hands from the steering wheel.
> Pay attention to the path of the vehicle. If the
traffic situation permits, accelerate carefully
> AX. The maximum parking speed is approxi-
mately 4 mph (7 km/h).
> Follow the visual instructions in the center dis-
play and the warning tones until the parking
process has ended.

ZX WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 117.
— The park assist is an assist system. The driv-
er is still responsible for monitoring the ve-
hicle's surroundings and preventing colli-
sions when using the system.
— When using park assist to drive into or out
of a parking space, the steering wheel turns
quickly on its own. Reaching into the steer-
ing wheel spokes while this is happening can
result in injury.

tomatically steers the vehicle out of the parking
space while the driver presses the pedals.
> Start the engine.
> Press the Pe button in the center console.
> Wait until a message appears in the center dis-
play that specifies the direction of travel re-
quired to exit the parking space.
> Activate the turn signal on the desired side or,
depending on vehicle equipment, press that
side next to the vehicle in the center display.
» Make sure the actual direction the vehicle is
traveling matches the direction indicated by the
park assist.
> Remove your hands from the steering wheel.
> Pay attention to the path of the vehicle. If the
traffic situation permits, accelerate carefully
> AX. The maximum speed for exiting a parking
space is 3 mph (5 km/h).
> Follow the visual instructions in the display and
the warning tones until the vehicle has finished
exiting the parking space.
>» The process of exiting the parking space has
ended if additional corrective movements are
no longer necessary and the specified steering
wheel angle is sufficient to drive out of the
parking space. Resume control of the steering
wheel >@).


G) Tips
You can also cancel the driving direction set
by the system by shifting between a forward
gear and reverse gear. Based on the position
of the vehicle, the system then calculates the
additional steering and driving directions for
maneuvering.

Exiting parking spaces with park assist
Applies to: vehicles with park assist
If you parked the vehicle in a parallel parking
space, park assist can help you drive out of it.

of a parking space, the steering wheel turns
quickly on its own. Reaching into the steer-
ing wheel spokes while this is happening can
result in injury.

@) Note
Resume steering immediately after the last
corrective movement and the takeover
prompt, so that the specified steering wheel
angle is not recentered.

Care and cleaning


follow the instructions from the car wash
operator.
—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.
—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.
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.
(*) 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
