General information on assist systems for Your Audi RS6 4 Door Fourth Generation (2019-2025)

General information on assist systems  
The lane departure warning can warn you  
that the vehicle is about to leave the lane and  
may indicate this by issuing corrective steering  
input and vibrating the steering wheel  
ðpage 142.  
General information on  
assist systems  
Overview of assist  
systems  
The lane guidance function helps you keep  
the vehicle largely in the centre of the lane by  
assisting with the steering ðpage 144.  
Warning systems  
Depending on the country and the vehicle’s  
equipment, the following assist systems may be  
installed in the vehicle:  
Speed assist systems  
The manual speed warning issues a warning  
when a set speed is exceeded ðpage 135.  
The traffic sign-based speed warning issues  
a warning when a speed limit that has been de-  
tected is exceeded ðpage 168.  
Depending on the country and the vehicle’s  
equipment, the following assist systems may be  
installed in the vehicle:  
The cruise control system helps keep the ve-  
hicle at a constant speed that you have set  
ðpage 147.  
The trailer-specific speed warning dis-  
plays trailer-specific speed limits and takes  
them into account ðpage 169.  
The speed limiter helps you avoid exceeding  
a specific speed that you have set ðpage 147.  
The predictive speed limiter automatically  
adapts the vehicle's speed to recognised speed  
limits ðpage 147.  
The distance warning issues a warning if the  
distance to the vehicle in front is insufficient  
ðpage 135.  
The side assist function uses a warning sig-  
nal on the exterior mirror to warn you of road  
users approaching from behind and vehicles in  
the blind spot when you are changing lane  
ðpage 136.  
The adaptive cruise control function assists  
you by controlling the road speed and maintain-  
ing a set distance to the vehicle in front. The  
system can accelerate and brake when it de-  
tects a vehicle in front. The system can also  
brake the vehicle to a standstill in congested  
traffic and traffic jams and may drive off again  
automatically depending on how long the vehi-  
cle remains stationary ðpage 150.  
The exit warning system can recognise traf-  
fic approaching from behind and warn you as  
you get out of the vehicle ðpage 138.  
The fatigue warning indicates whether  
stopping to rest is recommended ðpage 139.  
The distraction warning warns you when  
the system detects that you are distracted from  
the road ðpage 139.  
The adaptive cruise assist combines the  
predictive cruise control and the lane guidance  
function with the functions of the adaptive  
cruise control ðpage 159.  
The predictive cruise control function can  
adjust the set speed according to the environ-  
ment in which you are driving (e.g. according to  
speed limits or the road ahead) ðpage 156.  
Lane assist systems  
Depending on the country and the equipment fit-  
ted, your vehicle may have different lane assist  
systems.  
Systems for braking and taking evasive  
action  
Unlike the lane guidance function, which continu-  
ously keeps the vehicle in the centre of its lane  
with brief steering inputs when you are driving,  
the lane departure warning only provides a warn-  
ing and intervenes just before you inadvertently  
drift out of the lane.  
Depending on the country and the vehicle’s  
equipment, the following assist systems may be  
installed in the vehicle:  
129  
General information on assist systems  
The active front assist function can take ac-  
tion to protect the vehicle occupants and other  
road users in certain situations ðpage 161.  
The rear turn assist warns you of traffic ap-  
proaching from the rear when you are turning  
off ðpage 164.  
views of the area around the vehicle to help you  
when parking and manoeuvring ðpage 178.  
To familiarise yourself with the systems, Audi  
recommends that you practise parking in a quiet  
location or a car park. The weather and light con-  
ditions should be good.  
The rear cross-traffic assist can warn you  
about traffic approaching from either side while  
you are reversing or leaving a parking space  
ðpage 183.  
Assisted parking systems  
Depending on the country and the vehicle’s  
equipment, the following assist systems may be  
installed in the vehicle:  
The emergency assist identifies if the driver  
is inactive. The system issues a warning in such  
cases and, if necessary, takes over operation of  
the vehicle to bring it automatically to a stand-  
still in the same lane ðpage 160.  
The parking space search helps you find suita-  
ble parking spaces for the assisted parking  
functions ðpage 185.  
The park assist plus helps you manoeuvre  
the vehicle into and out of empty parking  
spaces. The system controls steering move-  
ments, gear changes, acceleration and braking  
ðpage 187.  
Further assist systems  
Depending on the country and the vehicle’s  
equipment, the following assist systems may be  
installed in the vehicle:  
The trailer assist helps you when driving and  
manoeuvring by steering the trailer in the de-  
sired direction when reversing and, where nec-  
essary, when making steering corrections while  
driving forward ðpage 125.  
The predictive efficiency messages (effi-  
ciency assist) help you to adapt your driving to  
the route ahead to reduce the vehicle's con-  
sumption ðpage 167.  
The traffic light information displays speed  
recommendations for reaching a series of green  
lights or the waiting time at the next traffic  
light ðpage 173.  
To familiarise yourself with the systems, Audi  
recommends that you practise parking in a quiet  
location or a car park. The weather and light con-  
ditions should be good.  
The camera-based traffic sign recognition  
system shows traffic signs which have been de-  
tected ðpage 168.

Parking systems  
Depending on the country and the vehicle’s  
equipment, the following assist systems may be  
installed in the vehicle:  
Safety information on the assist systems  
Please note the safety precautions for the sup-  
porting systems, sensors and cameras ð  
.
When you are parking, the parking aid with  
distance display warns you acoustically and vis-  
ually about obstacles detected ðpage 176.  
The reversing camera displays a picture of the  
area behind the vehicle captured by the camera.  
Orientation lines in the image assist you when  
parking and manoeuvring ðpage 178.  
WARNING  
As the driver, you always have full responsi-  
bility for the operation of the vehicle. The  
assist systems cannot replace the full con-  
centration of the driver. Always devote your  
full attention to the road and the traffic sit-  
uation, and be prepared to intervene at any  
time.  
The surround view cameras are an extension of  
the reversing camera; they provide various  
130  
General information on assist systems  
Only use the assist systems in situations  
where it is safe to do so. Always adjust your  
driving style to suit the visibility, weather,  
road and traffic conditions.  
The corrective steering/braking input from  
the assist systems may not be sufficient in  
some cases, or there may be no input from  
the systems at all. Be prepared to assume  
control at all times.  
Loose objects can be flung around in the  
passenger compartment in the event of sud-  
den driving or braking manoeuvres – risk of  
accident! Stow objects away safely while the  
vehicle is moving.  
Further information on the system limits of  
the assist systems  
The technology which enables the systems to  
detect the vehicle’s surroundings is subject to  
certain limitations; as a result, the systems  
may not warn the driver or intervene in time/at  
the appropriate time. In addition, it is possible  
that the assist systems may misinterpret driv-  
ing manoeuvres and give a warning or intervene  
unexpectedly.  
The assist systems are only able to react as  
intended when the sensors and cameras  
function without restrictions. Please observe  
the notes on the sensors and cameras  
ðpage 132.  
Further information on assist systems  
Poor road conditions caused by inclement  
weather and non-standard road conditions,  
such off-road terrain, unpaved or gravelly  
roads, or roads with heavy cambers or deep  
ruts, may prevent the system from functioning  
as expected.  
Always adhere to the locally applicable laws  
and regulations, particularly with regard to the  
driver’s responsibilities, as well as the permit-  
ted driving speeds, parking positions, position  
of the wheels, distance between vehicles, form-  
ing a lane for emergency vehicles, etc. As the  
driver you are always responsible for adhering  
to the locally applicable laws and regulations.  
You can cancel the steering/braking input from  
the system by firmly applying the brakes your-  
self, pressing the accelerator firmly, turning  
the steering wheel or deactivating the assis-  
tance system in question.  
The systems may not function as expected in  
unpredictable traffic situations such as in turn-  
ing lanes, at blind exits, in roadwork areas, in  
case of restricted vision at steep hill crests or  
valleys, at intersections, at roundabouts, at toll  
gates, in city traffic or when changing from  
driving on the right to driving on the left.  
The ability of the systems to detect the vehi-  
cle’s surroundings can be affected, for example,  
by vehicles travelling in front, rain, snow, heavy  
road spray or adverse light.  
Always check the current settings of the assist  
systems before setting off. The settings might  
have been changed by switching the vehicle off  
or altered by someone else.  
In towing mode, some assist systems may be  
restricted or unavailable, or may not react as  
usual. Please refer to the notes on towing a  
trailer ðpage 118.  
System limits of the assist systems  
Please note the system limits of the supporting  
systems, sensors and cameras ð  
.
The function that detects the driver’s hands on  
the steering wheel may be limited if you are  
wearing gloves. The steering assist systems  
may prompt you to take over the steering more  
frequently as a result.  
WARNING  
The assist systems cannot overcome the  
laws of physics; in some situations it may  
not be possible to prevent a collision.  
Equipment or accessories fitted on the steering  
wheel may restrict the function of the steering  
assist systems. In addition, the frequency with  
which the steering assist systems prompt you  
to take over the steering may differ.  
It is possible that the warnings, notifications  
or warning lamps may not be displayed or  
activated in time/at the appropriate time,  
e.g. if a vehicle is approaching very quickly.  
131  
General information on assist systems  
be fitted at the rear, front and side, depending on  
the vehicle’s equipment. The range depends on  
the location in which the ultrasonic sensors are  
fitted. The side zone is detected and analysed as  
the vehicle is moving past. When you switch the  
vehicle off and on again or open the door, or after  
the vehicle has been stationary for a while, the  
ambient surroundings may have changed. In this  
case, the side zone is not shown.  
Sensors for detecting  
the vehicle’s  
surroundings  
Areas covered by sensors and cameras  
Cameras  
Only use the camera image on the display to as-  
sist you if the picture is clear and discernible.  
Please also note that the view on the display is  
enlarged and distorted. Under certain circum-  
stances, objects may appear different on the dis-  
play, or may be depicted inaccurately.  
Fig. 78 Areas covered by the sensors  
The reversing camera is only able to detect the  
area shown in red 1 ðFig. 79. Only this area is  
shown on the centre display ð  
.
Further information  
Applies to: vehicles with surround view cam-  
eras: System limitations may occur if the exteri-  
or mirrors are not folded out completely. Make  
sure that the exterior mirrors are fully folded  
out while you are driving.  
Fig. 79 Area covered by reversing camera  
The assist systems evaluate the data from differ-  
ent sensors and cameras installed in the vehicle.  
Do not use the assist systems if the area around  
the sensors and cameras or the underbody has  
been damaged. This can impair the function of  
the sensors and cameras or cause malfunctions.  
Have the systems checked by a qualified work-  
shop.  
Applies to: vehicles with electric folding exteri-  
or mirrors: System limitations may occur when  
manually adjusting the exterior mirrors. The ex-  
terior mirrors must only be folded in/out elec-  
trically.  
The sensors and cameras and their surrounding  
area must never be covered or painted as this  
can impair the function of the systems that de-  
pend on them. Please ensure that the sensors  
and cameras are clean and kept free of snow,  
ice and any other deposits. Accessories, stick-  
ers, decals, paint etc. must not be applied to  
the sensors and must be kept completely out-  
side the sensors’ and cameras’ range of vision.  
When replacing a factory-fitted front number  
plate holder, the new holder must be of the  
same size and material as the original one. On  
vehicles without a factory-fitted front number  
plate holder, a holder must not be fitted in the  
front area, as this can impair the function of  
the vehicle’s systems.  
Radar sensors  
Depending on the vehicle’s equipment, the entire  
area surrounding the vehicle can be detected  
ðFig. 78.  
The radar sensors at the rear corners of the vehi-  
cle are designed for normal lane widths and mon-  
itor the lanes immediately to the left and right of  
your vehicle.  
Ultrasonic sensors  
The ultrasonic sensors detect the area surround-  
ing the vehicle at close range. The sensors may

General information on assist systems  
Poor light or visibility (for instance when enter-  
ing a tunnel), or glare from reflecting objects,  
etc. may restrict the function of the sensors  
and cameras.  
Positions of sensors and cameras  
External ultrasonic sources, such as from other  
vehicles, may interfere with the sensors.  
Further information on the areas covered by  
the sensors  
The areas covered by the sensors ðFig. 78 and  
cameras ðFig. 79 are examples and do not rep-  
resent the range to scale.  
Fig. 80 Front area: Sensors and cameras  
WARNING  
The sensors and cameras have certain areas  
in which they cannot detect the surround-  
ings. Objects, animals and persons in these  
areas may be detected only to a limited ex-  
tent or not at all. Always monitor the road  
and the area around the vehicle; do not rely  
on the sensors alone, and do not allow your-  
self to become distracted.  
Fig. 81 Rear area: Sensors and cameras  
Sensors may be subject to physical system  
limits. External sources of interference, such  
as from other vehicles, may impair the func-  
tion of the sensors. As a result, the assist
