2012 AUDI A8 parking sensors

94 Audi adap tive cruise control and br aking guard
stopped vehicle or stationary obstacle
(end of a traffic jam or veh icle that has
broken down in traffic).
- Always remember that the radar sensor
for the Audi braking guard works only
within defined detection and range limits
that may prevent the proper detection of
other vehicles .
- The radar sensor's function and range
can be reduced by rain, snow and heavy
spray. Moving vehicles up ahead may not
be promptly detected or may not be de­
tected at al l.
- Reflective surfaces includ ing crash barri­
ers or tunnel entrances may impair the
func tion of the radar sensor.
{D) Tips
- You can cancel the braking w ith increas­
i ng force that is initiated by the system
by braking yo urself, by accelerating no­
ticeab ly or by swerving.

Vehicles w ith the parking system advanced
are equipped with a rear view camera in addi­
tion to the acoustic and visua l parking system .
You can choose between two modes to assist
you with park ing. For example, you can use
"parking mode 1" when parking in a parking
space or garage
c::!;> fig . 121. When you want to
park parallel to the edge of the street, select
"parking mode 2"

Sensors in the bumper
Sensors are located in the front and rear
bumpe rs . If these detect an obstacle, audible
and visual signals warn you. The range at
which the sensors begin to meas ure is approx­
imately :
side 3 ft (0.90 m)
front 4 ft (1.20 m)
side 2 ft (0.60 m)
rear center 5.2 ft
(1.60 m)
The close r you get to the obstacle, the shorter
the interval between the audible signals. A
continuous tone sounds when the obstacle is
less than approximately 1 foot (0 .30 meters)
away. Do not continue driving farther!
If the distance to an obstacle remains con­
stant, the volume of the distance warning
gradually drops after about four seconds (this
does not apply in the continuous tone range) . ..,.

Rear vi ew cam era co ve ra ge area
The MM I display shows the area covered by
the rear view camera
c::> fig. 123 @ . Objects
that are not in the area covered @are not
shown on the MMI display.
We recommend that you p ractice park ing with
the rear view camera in a t raffic -free location
or parking lot to become familiar with the sys ­
tem, the orientation lines, and their function.
When doing th is, there sho uld be good light
and weather conditions.
In the MMI disp lay, objects or vehicles appear
closer or further away if:
- you are driving in reverse gear from a level
surface onto an incline, or a downward
s lope,
- you are d riving in reverse gear toward pro ­
truding objects,
- the vehicle is carrying too much load in the
rear.
The accuracy of the orientation lines and blue
surfaces dim inishes if:
- the adaptive air suspension/sport* is faulty, the vehicle is lifted or dynamic mode is se­
lected
c::> page 103,
- the rear view camera does not provide a reli­
able image, for examp le, in poor visibility
cond it ions or if the lens is dirty,
- the image on the screen is not visible due to
sun glare and reflect ion.
Car in g for the rear view came ra lens
The rear view camera is located above the rear
license plate bracket . For the parking system
to operate, the lens
c::> fig . 124 must be kept
clean:
- Dampen the lens with a household alcohol­
based glass cleaner, and then wipe the lens
clean with a dry cloth
c::> CD.
- Remove snow with a hand brush and ice
preferably with a de-icing spray
c::> (D .
A WARNING
,-
- Senso rs have blind spots in which objects
cannot be detected . Pay special attention to small children and animals because
the sensors cannot always detect them.
- The parking system cannot replace the
driver's attention. The driver alone is re­
sponsible for parking and similar driving maneuvers.
- Always keep your eyes on the vehicle 's
surroundings, us ing the rear view mirror
as well.
- Do not allow yourself to be distracted
from traffic by the rear view camera p ic­
tures.
- If the position and the installation angle
of the camera has changed, for example,
after a rear end col lis ion, do not continue
to use the system for safety reasons .
H ave it checked by a qualified dea le rship.
(D Note
- Low obstacles a lready s ignaled by a
warning can disappear from the system's detection range as they are approached
and w ill not cont inue to be signaled. Ob­
jects such as ba rr ier chains, trailer draw
bars, thin painted vert ica l poles or fen­
ces may not be detected by the system,
posing risk of damage .
- N ever use warm or hot water to remove
snow or ice from the rear view camera
lens - this could ca use the lens to crack!
- When cleaning the lens, never use prod ­
ucts that are abrasive.

Switching on and off
Applies to vehicles: with parking system advanced
The rear view camera switches on automati­
cally together with the acoustic and visual
park assist when you put the vehicle in re­
verse .

segments move closer to the veh icle. The co l­
lision area has been reached when the next to
las t segmen t is displayed . Do not continue
driving farther ¢.&

A WARNING
- The MMI display cannot show, or cannot
adequately show, certain objects (such as
small posts or grating), recesses in the
g ro und and protruding parts on another
car.
- Only use the rear view camera to assist
you if it shows a good, clear picture . For
examp le, the image may be affected by
the sun s hining into the lens, dirt on the
lens or if there is a defect.
- Use the rear view camera on ly with the
rear lid comp lete ly closed . Make sure any
objects you may have mounted on the
rear lid do not block the rear v iew cam­
era.
(D Tips
- The sensors must be kept clean and free
of snow and ice for the park assist to op­
erate.
- If your ve hicle is near an obstacle, an ad­
ditional v isual ind icator appears in the
rearview camera image. Th is superim­
posed image is there to help you to de­
termined which area of the vehicle is af­
fected .
- You can change the volume and pitch of the signals as well as the display

-What appears in the display is time-de­
layed .
