Description  
Applies to: vehicles with speed regulation systems  
Warning/indicator lamps on the speedometer  
and driver messages indicate the driving situa-  
tion and settings. The displays depend on the  
country and the vehicle’s equipment.  
The speed regulation systems consist of the  
cruise control system and the speed limiter.  
The cruise control system helps you to maintain  
a speed of approx. 20 km/h and above. The sys-  
tem regulates to the desired speed by braking  
and accelerating.  
Indicator lamps  
– The cruise control system is switched on and  
is actively controlling the set speed.  
The speed limiter helps you to avoid exceeding a  
speed of approx. 30 km/h and above. The system  
limits the speed even if the accelerator is press-  
ed.  
– The speed limiter is switched on and is ac-  
tively limiting the road speed to the threshold  
set.  
(flashing) – The set cruising speed has been  
exceeded; the driver is temporarily overriding the  
limit.  
WARNING  
– Please note the safety precautions and sys-  
tem limitations of the supporting systems,  
sensors and cameras ðpage 171 to  
Information is also provided in the head-up dis-  
play*.  
ðpage 174.  
WARNING  
– The speed regulation systems are designed  
to assist the driver; however the driver still  
maintains full responsibility for the opera-  
tion of the vehicle. This applies in particular  
to braking as well as to controlling the vehi-  
cle’s speed and distance to other vehicles.  
– When you take a turn-off, drive along a mo-  
torway exit lane or pass through roadwork  
sections, please temporarily switch off the  
speed regulation systems. This is to ensure  
that the vehicle does not accelerate to the  
cruising speed in such situations.  
Please note the safety precautions and system  
limitations of the supporting systems, sen-  
sors and cameras ðpage 171 to ðpage 174.

Applies to: vehicles with adaptive cruise assist  
Adaptive cruise assist  
How it works  
Applies to: vehicles with adaptive cruise assist  
Depending on the vehicle’s equipment, the adap-  
tive cruise assist may perform the following func-  
tions:  
The adaptive cruise control assists you by con-  
trolling the road speed and maintaining a set dis-  
tance to the vehicle in front within certain limits  
imposed by the system. When it detects a vehicle  
in front, the adaptive cruise control can acceler-  
ate and brake within certain system limitations.  
When there is no traffic in front, the adaptive  
cruise assist works just like a normal cruise con-  
trol system by maintaining a constant speed.  
When you draw closer to a vehicle in front, the  
adaptive cruise control matches your speed to  
that vehicle by automatically applying the  
brakes, and then maintains a constant distance  
(which you can adjust in the settings). As soon as  
it detects no more vehicles in front, the adaptive  
cruise control accelerates back up to the cruising  
speed.  
Fig. 126 Example: Driving into a bend  
In some driving situations, the adaptive cruise as-  
sist functions are restricted and you may need to  
intervene by, for example, braking the vehicle  
yourself:  
– When driving into a bend ðFig. 126 and driv-  
ing out of a bend, the system may react to a ve-  
hicle travelling in the next lane and therefore  
brake the vehicle. You can override this by ac-  
celerating briefly.  
– The system operates on the basis of informa-  
tion gathered from various sensors and cam-  
eras. Vehicles cannot be detected until they are  
within range and inside the sensors’ field of vi-  
sion ðpage 172, Fig. 116.  
– In tight bends, a vehicle driving ahead which  
has already been detected by the adaptive  
cruise assist may no longer be recognised, and  
Within certain system limits, the additional lane  
guidance function helps you to keep the vehicle  
largely in the centre of the lane. You can select  
whether the adaptive cruise assist provides assis-

the system may accelerate unexpectedly as a  
result.  
– The system will not react to stationary vehicles  
in the same lane if the system assumes that  
you can easily steer to avoid the stationary vehi-  
cle.  
– The system cannot react to stationary obsta-  
cles, such as the end of a traffic jam, particular-  
ly at high speeds.  
– The ability of the system to detect vehicles in  
front is limited when they are too close, travel-  
ling out of line, or moving into your lane.  
– Vehicles that are not clearly discernible, e.g. a  
motorcycle or cyclist travelling in front of you  
and vehicles with high ground clearance or a  
protruding load, are often identified late or are  
not detected at all.  
– The system does not react to pedestrians, ani-  
mals or crossing or oncoming traffic.

If the warning lamp  
lights up, actively take  
over the steering immediately. The system limits  
have been reached, for example because the sys-  
tem’s steering power is insufficient in tight  
bends. The system may no longer be active after  
a short time and may only be available again lat-  
er.

If the warning/indicator lamp or lights up  
and a corresponding message appears, actively  
take over the steering immediately. Insufficient  
steering activity has been detected or the system  
has reached its limits. Keep your hands on the  
steering wheel and be ready to steer at all times.  
If you do not take over the steering, the adaptive  
cruise assist will be stopped and the emergency  
assist will be activated on vehicles which have  
this function ðpage 216.  
How it works  
When the predictive control is active, the effi-  
ciency assist function adapts the cruising speed  
setting 1 for the adaptive cruise assist to recog-  
nised speed limits and the road layout ahead. Af-  
ter regulation for such events is completed, the  
adaptive cruise assist accelerates back up to the  
generally applicable speed limit or the recom-  
mended speed for the road in question.  
Depending on the equipment in your vehicle, the  
system can access data from the navigation sys-  
tem, from the camera behind the windscreen and  
from the radar sensors.

WARNING  
Overriding the predictive control  
– Please note the safety precautions and sys-  
tem limitations of the supporting systems,  
sensors and cameras ðpage 171 to  
ðpage 174.  
You can override the predictive control at any  
time by pressing the accelerator. In addition, the  
control lever ðpage 195, Fig. 130 can be used to  
change the speed limit control response.  
– Always direct your full attention to the road  
and surroundings, even when you are using  
the predictive control. It is always the driv-  
er's responsibility to assess the traffic situa-  
tion and take appropriate care.  
The predictive control is deactivated if you make  
a significant change to the speed limit control re-  
sponse. The adaptive cruise assist regulates the  
speed to match the manually set value.  
– The system does not give way to priority  
traffic and does not stop at traffic lights –  
risk of accident!  
Setting predictive control  
You can switch the predictive control on/off or  
adjust the individual settings under Adaptive  
cruise assist in the Driver assist menu  
ðpage 175. The settings depend on the equip-  
ment fitted in your vehicle.  
– The speed at which the system drives the ve-  
hicle through a corner may not correspond  
to your own driving style or ambient condi-  
tions. To avoid a risk of accident, apply the  
brakes manually as necessary, and reduce  
the speed setting in Adaptation to route  
ahead.  
Use speed limit – The regulation of the cruising  
speed according to speed limits ahead can be  
switched On or Off. The optional control setting  
With tolerance can also be applied. In this case,  
the actual speed can be above or below the set  
speed briefly for increased efficiency. This may  
result in a delay in observing the speed limit.  
Note  
– When using the predictive control, the ac-  
tual road speed may be above or below the  
maximum speed limit. It is always the driv-  
er's responsibility to keep within the speed  
limit.  
Adaptation to route ahead – The function for  
adapting to the route ahead can be switched Off  
or adjusted individually from Slow to Fast. This  
setting affects the handling characteristics of the  
predictive control, e.g. how fast the vehicle will  
drive through corners.  
– The actual traffic signs on your route always  
take precedence over the information on  
the display. As the driver you are always re-  
sponsible for adhering to the locally appli-  
cable laws and regulations.  
– The marking 1 is adjusted to the set speed  
when a speed limit is detected even when

the adaptive cruise assist is not regulating  
the speed.  
Setting the distance  
Applies to: vehicles with adaptive cruise assist  
– When the vehicle is coasting, the actual  
road speed may occasionally exceed or fall  
below the set speed.  
– The system’s control response depends on  
the driving program set for the adaptive  
cruise assist/the Audi drive select* mode se-  
lected.  
– After the ignition is switched on, a speed of  
1)  
130 km/h is set automatically when the  
vehicle is first driven onto a motorway or  
similar road, provided that no speed limits  
are detected and you have not set a differ-  
ent cruising speed.  
Fig. 135 Control lever: Setting the distance  
When you draw closer to a vehicle in front, the  
adaptive cruise assist matches your speed to that  
vehicle by applying the brakes, and then main-  
tains a constant distance (which you can adjust in  
the settings). If the vehicle in front accelerates,  
the adaptive cruise assist will also accelerate up  
to the target speed you have specified.  
1)  
– If a speed above 130 km/h has been set by  
the driver on motorways or similar roads,  
the vehicle will accelerate back up to this  
set speed after regulation for a specific  
event has been completed.  
– The system will only regulate the speed at  
motorway junctions or on slip roads if these  
are part of the route set in the route guid-  
ance.  
►
To display the current distance setting, briefly  
press the rocker switch.  
►
To increase or reduce the distance by one level,  
briefly press the rocker switch again towards  
+ / - .  
– If incorrect values are supplied by the cam-  
era-based traffic sign recognition* or if the  
map material on the navigation system* is  
out of date, this can cause failures or im-  
plausibilities in the control response.  
– While route guidance is active on the navi-  
gation system, the control uses the naviga-  
tion route as a reference. Implausibilities in  
the control response can occur when route  
guidance is inactive or if you leave the route.  
The newly set distance will be displayed briefly,  
e.g. indicator lamp .  
Setting the distance changes the gap between  
your vehicle and the one ahead. The higher the  
speed, the higher the distance. The following dis-

If you wish to merge into another lane due to  
your lane ending, for example, you can reduce  
the distance even further for a short time. In such  
cases, the adaptive cruise assist may also acceler-  
ate the vehicle above the set speed if necessary.  
If you operate the turn signal and the adaptive  
cruise assist concludes that you are intending to  
perform an overtaking manoeuvre, the system  
can accelerate before you change lane and reduce  
the distance to the vehicle ahead. This happens  
automatically if you are driving behind another

Fig. 119. The sensors are designed for normal  
lane widths and monitor the lanes immediately  
to the left and right of your vehicle. In certain sit-  
uations it is possible that the system may react  
to vehicles in your own lane or two lanes away, or  
to objects at the edge of the lane. The warning  
signal then lights up even though there are no  
vehicles in the critical area. Such situations may  
include:  
Available settings:
