Audi adaptive cruise
control
Description
Applies to: veh icles with Audi adaptive cruise contro l
Fig. 111 De tect ion range
The adaptive cruise control system is a combina­
t ion of speed and distance regulation.
It assists
the driver by both regulating the speed and
maintaining a distance to the vehicle driving
ahead, within the limits of the system . If the sys­
tem detects a veh icle driving ahead, the adaptive
cru ise control can brake and acce lerate your vehi­
cle . This increases driving comfort dur ing long
tr ips on highways and in stop-and -go traff ic (au­
tomatic transm iss ion*) .
What can adaptive cruise control do?
<( ~ The adaptive cruise contro l system uses video, ra-
"' ~ dar, ultrasound and navigation data. Veh icles

driving ahead can be recognized up to 650 feet
(200 m) away.
Predictive functions offer the driver additional
comfort and contr ibute to the reduction in fue l
consumption and CO2 emissions
¢ page 120.
On open roads with no traffic , it functions like a
cruise control system. The stored speed is main­
tained . When approaching a vehicle driving
ahead, the adaptive cruise contro l system auto­
matically brakes to match that vehicle's speed
and then mainta ins the set distance. As soon as
the system does not detect a vehicle dr iv ing
ahead, adaptive cru ise control accelerates up to
the stored speed .
Applies to: vehicles with automatic transmissions
In stop-and-go traffic, adaptive cruise control can
brake until the veh icle is stationary and then can
also start driving again automat ically under cer­
ta in cond itions
¢ page 117.
In traffic jams or stop-and -go traffic, traffic jam
ass ist can assist the
driver ¢ page 121.
Which functions can be controlled?
When you switc h adapt ive cruise control on, you
can set the current speed as the "contro l speed"
¢ page 115, Switching on/off.
When driving, you can stop cru ise control
¢ page 118 or change the speed ¢ page 117 at
any time.
You can also set the distance to the vehicle driv­ ing ahead and set the driving mode of the adap­
t ive cru ise control

General information
Applies to: ve hicles w ith Aud i adapt ive cruise co ntro l
Fig. 112 Fro nt of th e ve hicle: senso rs an d video camera
The areas with the radar and ultrasonic sensors
and the video camera ¢
fig. 112 must not be cov ­
ered by stickers, deposits or any other objects ,
because this can interfere with the adaptive
cruise control function. For information on clean­
ing, see
c::> page 362 . The same applies for any
modifications made in the front area .
In some driving situations , the adaptive cruise
control function is restricted :
-Vehicles can only be detected when they are
within the sensor detection zones
<:;> page 113,
fig. 111 .
-The system has a limited ability to detect
vehicles that are a short distance ahead, off to
the side of your vehicle or moving into your
lane.
-Objects that are difficu lt to detect such as mo­
torcycles, vehicles with high ground clearance
or an overhanging load are detected late or not
detected at all.
-When driving through curves
c::>page 115 .
-When the vehicle is stationary <:;> page 115.
_& WARNING
Always pay attention to the traffic around you
when adaptive cruise control is switched on.
As the driver, you are still responsible for your
own speed and the distance to other vehicles.
The adaptive cruise control is used to assist
you. The driver must always take action to
avoid a collision. The driver is always responsi­
ble for braking at the correct time.
114
-For safety reasons, do not use adaptive
cruise control when the road surface is in
poor condition and/or in bad weather condi­
tions (such as ice, fog, gravel, heavy rain and
hydroplaning) . Using the system under
these conditions increases the risk of an ac­
cident.
- Switch adaptive cruise control off tempora­
rily when driving in turning lanes, on ex­
pressway exits (except if predictive control
is switched on) or in construction zones.
This prevents the vehicle from accelerating
to the stored speed when in these situa­
tions.
-The adaptive cruise control system will not
brake by itself if you put your foot on the ac­
celerator pedal. Doing so can override the
speed and distance regulation.
-When approaching stationary obstacles
such as stopped traffic, adaptive cruise con­
trol will respond with limited function .
- Adaptive cruise control does not respond to
people, animals, or crossing or oncoming
objects.
-The function of the radar sensors can be af­
fected by reflective objects such as guard rails, the entrance to a tunnel, heavy rain or
ice .
(D Note
The sensors can be displaced by impacts or damage to the bumper, wheel housing and underbody. This can impair the adaptive
cruise control. Have an authorized Audi dealer
or authorized Audi Service Facility check their
funct ion.

In curves
Applies to: vehicles with Audi adaptive cruise contro l
Fig. 113 Example: driving into a curve
When driving into a curve <=>fig. 113 and out of a
curve , the adaptive cruise control may react to a
vehicle in the neighboring lane and apply the
brakes. You can prevent that by pressing the ac­
celerator pedal briefly.
Stationary vehicles
Applies to: vehicles with Audi adaptive cruise control
)))
Fig. 114 Example: vehicle changing lanes and stationary
vehicle
Within the limits of the system, adaptive cruise
control can react to stationary vehicles
c::> fig. 114, as long as you are driving slower than
30 mph (SO km/h) and the system classifies the possible passing maneuver as low. For example,
if a vehicle that was already detected
@ turns or
changes lanes, the adaptive cruise control reacts
to the stationary vehicle ahead of
it @ .
Assistance systems
Vehicles with manual transmission
Applies to: vehicles with Audi adaptive cruise control and
manual transmissio n
The adaptive cruise control is available from 1st
gear through 6th gear in the normal speed
range .
When the adaptive cruise control is turned on,
you must press the clutch to shift gears (as usu­ al). When shifting normally or when pressing the
clutch, the adaptive cruise control remains
turned on.
After you have engaged the gear, you do
not
need to press the gas pedal. The adaptive cruise
control accelerates automatically if necessary .
If you press down on the clutch for too long or
shift/couple improperly, the adaptive cruise con­
trol may turn off automatically.

w ill change in the instr ument cluster display.
When approaching a vehicle driving ahead, the
adaptive cruise control system brakes to match
that vehicle's speed and then adjusts to the set
distance. If the vehi cle driving ahead accelerates,
then the adaptive cruise control will also acceler ­
ate up to the speed that you have set .
The higher the speed, the greater the distance
c:> &. The Distance 3 setti ng is recommended .

That is equal to the general recommendation of
"half the speed shown on the speedometer".
The distances provided are specified val ues. De­
pending on the d riving situation and how the ve­
hicle ahead is driving, the actual distance may be
more or less than these target distances.
If you change the time gaps, the newly se t value
appears briefly in the instrument cluster display,
for example
II for Distance 3. This only occurs if
the
Driver assistance disp lay is not currently
shown in the display

Distance 1 : this setting corresponds to a distance
of 92 feet (28 meters) when traveling at 62 mph
(100 km/h), or a time distance of 1 second.
Distance 2 : this setting corresponds to a distance
of 118 feet (36 meters) when traveling at 62
mph (100 km/h), or a time distance of 1.3 sec­
onds.
Distance 3: this setting corresponds to a distance
of 164 feet (SO meters) when traveling at 62
mph (100 km/h), or a time distance of 1.8 sec­
onds.
Distance 4: this setting corresponds to a distance
of 219 feet (67 meters) when traveling a t 62

Predictive control
(efficiency assist)
Description
Applies to: vehicles with Audi adaptive cruise control and pre·
dict ive efficiency assist
Fig. 122 Instrument cluster: predictive control
General information
The predictive control 1l uses the map informa·
tion from the navigation system in order to react
proactively when driving. Information from the
camera -based traffic sign recognition* is also ap·
plied to recognize traffic signs
r::!> page 109.
When coming up to areas with speed limits or
changes in the course of the road (such as curves,
inte rsections or traffic circles), the system brakes
automatically and then accelerates back up to
the set speed.
When adaptive cruise cont rol is switched off, the
system only provides notificat ions without con­
trolled intervent ions
r::!> page 112 .
The driver can override the predictive control at
any time by pressing the accelerator or brake
pedal. If the system changes the vehicle speed to
adapt to speed limits, you can ch ange the speed
using the lever
<:!> page 117 , fig . 117 .
Always switch off the predictive control in
the following situations:
- When increased attention is needed from the
driver .
- In poor we ather condit ions such as snow or
heavy rain .
- When driving on roads in poor condition.

ability of the predictive control.
The symbol appears when the system
i s regulating the speed to match a speed limit .
If
this is the case, the system is regulating a speed
of 50 mph (80 km/h). The speed is then taken
over by the adaptive cruise control. The speed in
the speedometer LED ring adjusts to the speed to
be maintained

-Pay attention to traffic and the area around
your vehicle when predictive control is
sw itched on. The driver is always responsi­
ble for assessing the traffic situation.
-There is an increase in the risk of an acci­
dent, because the system does not consider
"right of way" rules and also does not re-
spond to traffic lights.
