2011 AUDI A5 CABRIOLET sensor

lffll.___A_ u_ d_i_ s_ id_ e_ a_s _s_ i_ s _t _________________________________________________ _
The detection~ page 13 7, fig . 142 of the radar sensor detection
area is made up of:
• the approach area (light green area)
(D, about 230 feet (70 m)
behind the vehicle, and
• the "blind spot" (dark green area)@.
The radar sensors cover the adjacent left and right lanes. Other lanes
are
not covered by the radar sensors .
rn Tips
Side assist does not measure actual lane width. The system assumes
a fixed lane width. Detection in the left and right lanes is based on
this assumed lane width. When driving on narrow roads or when
driving to the left or right of the center of a travel lane, it is possible
that vehicles will be detected that are
not in the lane next to the lane
you are using~

Operation
Side assist compares the distance and difference in speed of detected
vehicles with the speed of your vehicle . Whenever the difference in
speed and distance is registered as notab le if you were to change
lanes , a signa l light appears on the respective mirror .
The signal can light up if you are passed by a vehicle or if you are
passing another vehicle .
If you pass another vehicle slowly (difference in speed less than 9
mph, or 15 km/h), the signa l light will come on as soon as the other
vehicle is in your blind spot and is detected by side ass ist. When the
difference in speed is greater, the signal light will not come on. •
Appli es to vehicles : with si de assist
Informational and alert stage signals
Side ass ist has two signal stages:
• the informational stage signal, and
• the alert stage signal.
Side assist helps you by using the appropr iate signal stage,
depending on whether or not you have activated the turn signal, and
thus have indicated that you are or are not changing lanes.
Informational stage signal
As long as you have not activated the turn signal, s ide assist informs
you of detected vehicles that are reg istered as being in a notable loca ­
tion if you were to change lanes . Whenever the detected vehicle's
difference in speed and distance is registered by side assist as
notable , the signal light on the respective mirror produces muted
illumination.
Th e brightness of the informat ional stage signal is designed not to be
as intense, so that it does not interfere with your view of the road
when you are driving and have no intention of changing lanes. When
you look in the outs ide mirror, you can clearly see the informational
stage signal.
Alert stage signal
When you act ivate the turn s ignal , and side assist has detected a
vehicle in a notable location on that particular side , the signal light on
this side mirror flashes brightly. The repeated brief and bright
flashing of the alert stage signal reminds you to carefully check
traffic to the rear in the outside mirror and over your shoulder, so that
you can safely complete the lane change~

& WARNING
• Improper reliance on the side assist system can cause collisions
and serious personal injury:
-Never rely only on side assist when changing lanes .
- Always check rear view mirrors to make sure that it is safe to
change lanes.
• Side assist cannot detect all vehicles under all conditions­
danger of accident!
• Side assist cannot detect vehicles in time to alert you when
they approach from behind at very high speed , or fall drop back
very quickly .
• The radar sensor's
vision can be reduced or entirely blocked by
rain, snow, and heavy spray. This can result in side assist not
adequately detecting vehicles or, in some cases , not detecting
them at all. Always keep an eye on the direction you are traveling and the relevant area around the vehicle .
• Please note that side ass ist indicates there are approaching
vehicles, or vehicles in your blind spot, only after your vehicle has reached a driving speed of at least 19 mph (30 km/h).
• Side assist signal does not work around tight corners (turning
radius less than 328 feet, or 100 m ).
• Side assist is no replacement for the driver's full attention . The
driver alone is responsible for lane changes and similar driving
maneuvers. Always keep an eye on the direction you are traveling
and the relevant area around the vehicle. .,,

• Improper use of the Audi drive select can cause collisions,
other accident s and serious personal injury.
• Never drive at speeds that are too high for traffic , road and

Parking system
Different park assist systems may be used for parking or
maneuvering , depending on the vehicle's features .
Parking system (rear)*:
For the parking system, the acoustic park assist system is installed in
the rear of the vehicle=>
page 162.
The rear pa rk ing assist system uses ultrasonic sensors to determine
the distance of the vehicle from a detected obstacle. There are a tota l
o f f our sensors located on the rear bumper (two in the m iddle and
two on the sides) .
Parking system (rear, with rear-view cam era)*:
For the parking system (rear, with rear-view camera) , the rear
acoust ic park assist sys tem is integra ted in the rear of the vehicle and
the rear-v iew camera is integrated in the rear lid=>
page 166.
The parking system (rear, with rear-view camera) uses ultrasonic
sensors to determine the d istance of the vehicle from a detected
obstacle. There are a total of four sensors located on the rear bumper
(two in the m iddle a nd two on the sides). •

Rear acoustic park assist
The rear acoustic park assist warns you of obstacles or
objects behind your car .
Description
The rear acoust ic par king assist sys tem determines the d ista nce of
the vehicle from an obstacle using ultrason ic sensors . There are 4
sensors in the rear bumper .
T he range at which the sensors start to measure is
about :
To the side
Center rear
Act ivation 2
ft (0.60 m)
5
.2 ft (1.60 m)
Aco ust ic parking assist is act ivated automatically when
re ver se gear
is engaged . A b rief tone confirms that the system is activated .
Warning tones
Distance warning is given by chimes wh ich are generated by the rear
signa l generator . The vo lume and the pitch of the chimes can be
adjusted in the radio or i n the MM!*=>
page 163 .
Reversing
Distance warning when reversing starts when an obstacle is detected
in the range o f the pa rking assist system. As the d istance decreases,
the time interval between the audible tones becomes shorter .
When the distance is less than 1ft (0.30 m), the tone becomes
c ont inuous. At this point you should stop back ing up.

______________________________________________________ P_a _ r_ k_ a_ s_s _i _ s _t __ _
Please note that low objects already signaled by a warning can disap­
pear from the system's detection range and will not continue to be
signaled.
If the distance to an obstacle remains the same, the vo lume of the
distance warning is gradually reduced after about 4 seconds.
Approaching another obstacle will result in the distance warning
sounding at the normal volume again.
Malfunctions in the system
If a warning tone is aud ible for about five seconds when you turn on
the ignition , there is a malfunction in the system. Have the problem
corrected by your authorized Audi dealer.
Keep the sensors in the rear bumper clean and free from ice so that
the acoustic park assist system can function properly.
& WARNING
• Sensors have dead spaces in which objects cannot be detected.
Be especially alert for small children and animals, since they are
not always detected by the sensors.
• The Acoustic Parking System is not a substitute for the driver's
own caution and alertness. Ultimate respon sibility always
remains with the driver during parking and similar maneuvers.
Always watch where you are driving.
• You should always adjust the volume and frequency of the
chimes so that you can easily hear the acoustic distance warning
even if the radio is playing, the air-conditioner blower is on High
or there is a high level of outside noise .
- Check the settings whenever anyone else has driven the
vehicle before you.
0 Note
• Remember that low obstacles for which a warning has already
been issued may "dive" below the system 's sensing zone if the veh icle
is be ing backed up closer . In this case, the warning sound shutting off
Controls and equip ­
ment Safety first
does not ind
icate that you have cleared the obstacle . Instead, impact
is immin ent.
• Objects such as trai ler hitches, chains, narrow posts or fences
covered by a thin layer of paint may not always be detec ted by the
system . They can still damage your vehicle w ithout warning .
lI] Tips
Keep the sensors in the rear bumper clean and free of snow and ice so
that the aco ustic parking assist system can function properly.•

Adjusting the chimes
The volume and the pitch (frequency) of the chimes can
be adjusted in the radio or in the /11/111*.
