Audi adaptive cruise
control
Description
A ppl ie s to: ve hicles w ith Audi adaptive cruise co ntro l
Fig. 107 Detect ion range
The adaptive cruise control system is a combina­
tion of speed and distance regulation.
It assists
the dr iver 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 vehicle 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 transmission*).
What can adaptive cruise control do?
The adaptive cruise contro l system uses video, ra­
dar, ultrasound and navigation data. Veh icles
108
driving ahead can be recognized up to 650 feet
(200 m) away.
P red ictive functions offer the driver additional
comfort and contribute to the reduction in fue l
consumption and CO2 emiss ions
r:!> page 115.
On open roads with no traffic , it functions like a
c ruise 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 maintains the set distance . As soon as
the system does not detect a vehicle dr iving
ahead, adaptive cruise control accelerates up to
the stored speed.
App lies to: vehicles wit h auto matic 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
r:!> page 112 .
In traffic jams or s top-and-go traffic, traffic jam
ass ist can ass ist the driver
r:!> page 116.
Which functions can be controlled?
When you switch adapt ive cru ise control on, you
can set the current speed as the "contro l speed"
r:!> page 110, Switching on/off.
When dr iving, you can stop cruise control
c:>page 113 or change the speed c::;,page 112 at
any time .
You can also set the distance to the vehicle driv­ i ng ahead and set the driving mode of the adap­
tive cru ise cont rol

Fig. 118 Instrument cluster: pred ictive control
General information
The predictive control 1l uses the map informa­
tion from the navigation system in order to react
proact ively when driv ing. Information from the
camera-based traffic sign recognition* is also ap­ plied to recognize traffic signs
<:!)page 104.
When coming up to areas with speed limits or
changes in the course of the road (such as curves,
intersections or traffic circles), the system brakes
automatically and then accelerates back up to
the set speed .
When adaptive cruise control is switched off, the
system only provides notifications without con­
trolled
interventions ¢ page 107.
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 change the speed
using the
lever ¢ page 112, fig. 113 .

Audi active lane assist
Description
Applies to: ve hicles wit h Aud i act ive lane ass ist
Active lane assist (lane departure warning) de­
tects lane marker lines within the limits of the
system using a camera in the windshield . If you
are approach ing a detected lane marker line and
it appears likely that you will leave the lane, the
system w ill wa rn you w it h corre ct ive steer ing .
You can overr ide th is steering at any time . If yo u
pass over a line, the steer ing whee l wi ll vibrate
lightly. In order for this warning vibration to oc ­
cur, it must first be switched on in the Infotain­
ment system. Active lane assist is ready for oper­
ation when the lane marker line is detected on at least one side of the vehicle.
The system is designed for driving on express ­
ways and highways and therefore only activates at speeds above approximately 40 mph (6S km/
h).
Applies to: vehicles with side assist: if you acti­
vate a turn signal when active lane assist is ready
and it classif ies a lane change as critical because
of vehicles traveling alongside you or approach­ ing you, there w ill be not iceable correct ive steer­
i ng shortly before you leave the lane . This will at­
tempt to keep your veh icle in the la ne.
Applies to: vehicles w ithout s ide ass ist : the ready
system does not warn you if you activate a turn
A ss ista nce sys te m s
signal before crossing the lane marker line. In
t h is case, it assumes that you are changing lanes
intentionally .
Applies to: vehicles wi th adap tive c ruise contro l:
there is no corrective steering or warnings if the
system recognizes a distinct passing maneuver .
If the condit ions are met, traffic jam ass ist
switches on at speeds under approximately
40 mph (65 km/h)
qpage 116.
A WARNING
=
- The system warns the driver that the vehicle
is leaving the lane using corrective steering.
The driver is always responsible fo r keeping
the vehicle within the lane.
- The system can help you keep the vehicle in
the lane, but it does not drive by itself. Al­
ways keep your hands on the stee ring
wheel.
- Cor rective stee ring may not occur in certain
situations, such as during heavy b raking.
- There may be cases whe re the camera does
not recognize all lane marker lines. Cor rec­
tive steering can only take place on the s ide
of the vehicle where lane marker lines are
detected.
- Other road structu res or objects could poss i­
b ly be identified unintentionally as lane
marker lines . As a result, corrective steering
may be unexpected or may not occur.
- The camera view can be restricted, for ex­
ample by vehicles driving ahead or by rain,
snow, heavy spray or light shining into the
camera. Th is can result in active lane ass ist
not detecting the lane marker lines or de­
tect ing them incorrectly .
- In certain s ituations where visibility is low,
the vehicle may switch from an "early" to
"late" steering correct ion.
- Under certain condit ions such as ruts in the
road, an inclined roadway or crosswinds, the
correct ive steer ing alo ne may not be enough
to keep the vehicle in the middle of the lane .
- For safety reasons, act ive lane assist must
not be used when there are poor road and/
or weather conditions such as slippery roads, fog, gravel, heavy rain, snow and the

traveling with you within sensor range
(D
¢ fig. 12 7. If a lane change is classified as criti­
ca l, the display @in the exterior mirror turns on
¢fig. 128.
The display in the left exterior mirror provides as­
sistance when making a lane change to the left,
while the display in the right exterior mirror pro­
vides assistance when making a lane change to
the right.
Information stage
As long as you do not activate the turn signal,
side assist
informs yo u about vehicles that are

detected and classified as crit ical. The display in
the mirror turns on, but is dim .
The display remains dim in the information stage
so that your view toward the front is not distur­
bed.
Warning stage If the d isplay in a mirror blinks brightly when you
activate a turn signal, side assist is
warning you
about detected vehicles that it has classified as
critical. If this happens, check traffic by gla nc ing
in the exterior m irrors and over your shoulder
c::> .&. in General information on page 130 .
Applies to: vehicles with active lane assist : the
d isplay i n the mirror can also blink if you have not
act ivated a turn signal: if you are app roaching a
detected lane marker line and it appears you will
be leaving the lane, side assist will warn you
about detected vehicles that it ha s classified as
critical.

@ Vehicles that are approaching
In certain cases, a vehicle will be classified as
critical for a lane change even if it is still some ­
what far away . The faster a vehicle approaches,
the sooner the display in the exterior m irror will
turn on.
@ Vehicles traveling with you

Assistance systems
Description
Applies to: vehicl es w ith Aud i drive select
The follow ing systems, among other things, are
influenced by drive select:
Engine and automatic transmission*
Depending on the mode, the engine and auto­
mat ic transmission* respond more quickly or in a
mo re balanced manner to accelerator pedal
movements . In the sporty
Dynamic mode , the
transmission shifts at highe r speed ranges.
Suspension control*
The suspension control* uses sensors to record
information regard ing steering movements ,
braking and acceleration operations by the driv­
er , road surface, driving speed, and load. This
makes it possible to adapt damping to the driv­
ing situation nearly in rea l time. With drive se ­
lect, you can adjust the suspension control to
sporty
( Dynamic ), comfortab le ( Comfort ) or bal­
anced
( Auto ).
Steering
The power steering adapts. Indi rect s teer ing that
moves easily as in
Comfort mode is especia lly
suited to long drives on highways . The
Dynamic
mode provides sporty , direct steering.
The following applies to vehicles with dynamic
steering* : the steering ratio changes based on
vehicle speed in order to maintain optimum
steer ing effort for the driver at all times . This
sets the steering to be less sensitive at higher
speeds in order to prov ide improved vehicle con­
trol. At reduced speeds, steering is more direct in
order to keep the steering effort as min imal as
possible when the driver is maneuvering the vehi­
cle. At low and average speeds, dynamic steer­
ing* additionally provides more responsive steer­
ing performance.
Sport differential*
As a component of the all wheel drive system
(quattro)
~ page 1 SO, the sport differential dis­
tributes the driving power to the rear axle de­
pending on the situation. The distribution of
power varies depending on the selected mode
134
from moderate (Comfort ) to sporty (Dynamic ).
The goal is a high level of agility and ability to ac­
ce lerate on curves . The vehicle is very respons ive
to steering.
Adaptive cruise control (ACC)*
The behavior when accelerating can be adjusted
from comfortable to sporty, depending on the
drive select mode. Adaptive cruise control also
responds to the driving behavior of the vehicle
ahead in a more conservative or sporty manner.
Engine sound*
The engine sound adapts to the current mode
and can be subtle to sporty.
@ Tips
The S selector lever position automatically en­
gages when the
Dynamic mode is selected .
Selecting the driving mode
Applies to: vehicles with Audi drive se lect
Fig. 135 Center co nsole: controls for drive se lect
.,. Press the left or right a rrow key ~ fig. 135 until
the desired mode appears in the instrument
cluster/ Infotainment system disp lay. Or
.,. Select in the Infotainment system: IMENU j but-
ton
> Vehicle > Audi drive select.
.,. Select and confirm the desired setting.
You can change the driving mode when the vehi­
cle is stationary or while driving. If traffic per­
mits, after changing modes, briefly take your
foot off the accelerator pedal so that the recently
selected mode is also activated for the engine.
