rectly when you use these mirrors to gauge
your distance from the vehicles behind you
when changing lanes, which increases the risk of an accident .
Q) Note
- Applies to vehicles with power folding exte­
rior mirrors: if the mirror housing was
moved by outside forces (such as an impact
when maneuvering), you must use the pow­
er folding function to fold the mirror all the
way out. The mirrors will make a loud noise
when they latch into place. The mirror hous­
ing must not be moved back into place by
hand because this would impair the func­
tion of the mirror mechanism.
-Applies to vehicles without power folding
exterior mirrors: if the mirror housing was
moved by outside forces (such as an impact
when maneuvering), you must move it back
in place by hand.
- If you wash
th@ vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
Never fold power folding exterior mirrors*
by hand . Only fold them in and out using
the power controls.
{!) Tips
-If the power adjusting function malfunc­
tions, the glass in both mirrors can be ad­
justed by pressing on the edge of it by hand.

lyte fluid can lead to irritation of the air­
ways, especially in people with asthma or
other respiratory conditions. Take deep
breaths immediately after leaving the vehi­
cle or, if this is not possible, open all of the
doors and windows as wide as possible.
- If electrolyte fluid enters the eyes, flush
them thoroughly with a large amount of
clean water for at least 15 minutes and then
seek medical attention.

the skin, flush the affected area with clean
water for at least 15 minutes and then clean
with soap and water and seek medical at­
tention . Clean affected clothing and shoes
thoroughly before wearing again.
- If the fluid was swallowed and the person is
conscious, flush the mouth with water for at least 15 minutes . Do not induce vomiting
unless this is recommended by medical pro­
fessionals . Seek medical attention immedi­
ately .

@ Vehicles that are approaching
In certain cases, a vehicle will be classified as
critical for a lane change even if it is still some ­
what far away . The faster a vehicle approaches,
the sooner the display in the exterior m irror will
turn on.
@ Vehicles traveling with you
Vehicles traveling with you are indicated in the

If you s lowly pass a veh icle that s ide assist has
detected (the difference in speed between the
vehicle and your vehicle is less than approximate­
ly 9 mph ( 15 km/h)) , the disp lay in the exter ior
mirror turns on as soon as the vehicle en ters your
blind spot.
The display w ill not turn on if you quickly pass a

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*

-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.

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 .
