Audi adaptive cruise
control
Description
App lies to : vehicles wi th Audi adap tive c ru ise con trol
Fi g. 89 Detect io n range
The adaptive cru ise cont rol system is a comb ina­
tion of speed and dis tance regu lation.
It ass ists
t h e d river by bo th regu lating the speed and
maintain ing a d is ta nce to the vehicle driv ing
ahead, within the limits of the system. If the sys ­
tem detects a vehicle d riving ahead, the adaptive
cruise contro l can brake and accelerate yo ur vehi­
cle. T his makes driving more comfo rtable both
o n long st retches of hig hway and in stop-and-go
traffic .
What can adaptive cruise control do?
The adaptive cru ise control system uses video, ra­
dar, ultrasound and navigat ion data . Vehicles
driv ing ahead can be recognized up to 650 feet
(200 m) away .
Pred ictive functions offer the drive r additional
comfort and contr ibute to the reduct ion in fuel
consumption a nd CO2 em issions
r::::> page 102.
On open roads with no traffic, it functions like a
cruise contro l system. The stored speed is main ­
ta ined . When approaching a vehicle d riving
ahead, the adaptive cruise contro l system auto­
matically brakes to match that vehicle's speed
and then maintains the set dis tance. As soon as
the system do es not detect a vehicle dr iv ing
ahea d, adaptive cruise cont rol accelerates up to
t h e s to red spee d.
In stop-a nd-go traffic, adap tive cruise control can
brake until the veh icle is sta tionary a nd then can .,.

General information
The predict ive control 1> 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
c::> page 24. When
coming up to areas with speed limits or changes
in the course of the road (such as curves, inter­
sections or traffic c ircles), the system brakes au­
tomatically 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
c::> page 95.
The driver can override the predictive contro l at
any time by pressing the accelerator or brake
pedal. If the system changes the veh icle speed to
adapt to speed limits, you can change the speed
using the lever
c::>page 99 , fig . 95.
Always switch off the predictive control in
the following situations:
-When increased attention is needed from the
driver .
- In poor weather conditions such as snow or
heavy rain .
- When driving on roads in poor cond ition.

for the first time, th e availability of predictive
control is displayed in the status line with the m essage
ACC: 1111 + B active.
The symbol appears when the system
is regulating the speed to match a speed limit. As
an example, the system is regulating a speed of
50 mph (80 km/h) in this scenario. The speed is
then taken over by the adaptive cruise control.
The speed in the speedometer LED line also ad­
justs to the speed to be maintained

A WARNING
- Read the warnings on c::> & in General infor ­
mation on page 97
and on c::> & in Descrip­
tion on page 24 .
- Pay attention to traffic and the area around
your vehicle when predictive control is switched on. The driver is always responsi­
ble for correctly assessing the traffic situa­
tion.
- 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 .
- The system only considers traffic signs that
give a speed limit.
Assist
- The permitted speed can be exceeded if the
adaptation to a speed limit is incorrect. The
driver is responsible for adhering to the per­
mitted speed.
- The speed at which a curve is driven through
does not necessarily match your own driving
style . Brake the vehicle yourself when need ­
ed to reduce the risk of an accident.
(D Tips
-If a speed limit is detected, the stored
speed is also adjusted in the speedometer
LED line when the adaptive cruise control is
not active.
- The adaptation by the system depends on
the driving mode set in drive select* .
- Switching off predictive control, for exam­
ple when driving in low traffic zones, does
not cause the adaptive cruise control to
switch off .
-After switching on the ignition, the system
initially adjusts to a speed of 80 mph
(130 km/h) when driving onto highways
without a speed limit. Then the system ad­
justs to the last speed stored by the driver.
- There is no adaptation to speed limits when
driving through highway interchanges and
when driving on or off the expressway.
- There is no predictive control at speed limits
under 20 mph (30 km/h).
- If a speed limit is only detected by the cam­
era and the actual speed is significantly
higher, then the speed limit will blink in the
display until you have reached the required
speed
c::> page 25.
- Incorrect values from the camera-based traffic sign recognition* or outdated naviga­
tion system map data can lead to incorrect
or implausible control.
- When route guidance is switched on, the
system adapts to the route provided by the
navigation system. Driving without route
guidance or leaving a route can result in im­
plausible control.
- The system switches
off when outside of a
road system that is recorded in the naviga­
tion system map data.

Ass is t
- Note that the reversible belt tensioner on
the front passenger's side deactivates when
the front passenger's a irbag is deactivated.
- Switch the pre sense off when you are not
using public streets or when loading the ve­
hicle onto a vehicle carrier, train, ship or
other type of transportation. This can pre­
vent an undes ired intervention from the pre
sense system .

Audi pre sense city
' Description
App lies to : vehicles wit h Audi pre sense city
Within the limits of the system, pre sense city
can warn you of impending collisions with
vehicles and pedestrians and initiate the applica­
ble braking maneuver if needed. Pre sense city is
active at a speed of 6 mph (9 km/h) and higher.
A pedestrian warning can occur at speeds up to 50 mph (85 km/h), and vehicle warnings can oc­
cur at speeds up to 155 mph (250 km/h). A pre
sense city braking maneuver is possible at speeds
up to 50 mph (85 km/h).
Warnings
App lies to: vehicles wit h Aud i pre sense city
The system recognizes various dangerous situa­
tions. The
early warning occurs when:
- a vehicle driving ahead brakes sudden ly,
- your own vehicle approaches a sign ificantly
slower vehicle or stationary vehicle in the direc­
tion of travel.
- a pedestrian is standing in the lane or is moving
into the lane.
When this warning occurs, it may only be possi­
ble to avo id a collision by swerving or braking
strongly. The message
Audi pre sense.
~ page 108, fig. 104 and a warning tone will
warn you about the danger.
Additionally, a jerk on the brakes may occur as an
acute warning when there is an impend ing colli­
sion . If you do not react to the acute warning, pre
sense city can brake to the point of complete de­
ce leration within the limits of the system. This
reduces the vehicle speed in the event of a colli­
sion. The message

A WARNING -,..___
-Pre sense city cannot overcome the laws of
physics. It is a system designed to assist and
it cannot prevent a collision in every circum­
stance. The driver must always intervene.
The driver is always responsible for braking at the correct time . Do not let the increased
safety provided tempt you into taking risks.
This could increase your risk of a collision .
- The system can deploy incorrectly due to
system-specific limits.
- To reduce the risk of an accident, please
note that the camera does not always detect
every object .
- Pre sense city does not react to animals,
crossing or oncoming vehicles, objects such
as bars, railings or railcars, and objects that
are difficult to detect~&.

Audi active Lane assist
Description
Applies to: veh icles w ith Audi active lane assist
Active lane assist (lane departure warning) de­
tects lane ma rker lines withi n the l imits of the
system using a camera in the windshield. If you
are approaching a detected lane marker line and it appears likely that you will leave the lane, the
system will warn you w ith corrective stee ring .
You can override this steering at any time . If you
112
pass over a line, the steering wheel will vibrate
lightly. In order for this warning vibration to oc­
cur, it must first be switched on in the Infotain­
ment system. Active lane ass ist is ready for oper­
a tion when the lane marker line is detected on at
least one side of the vehicle .
T he system is des igned for driving on express­
ways and highways and therefore on ly activates
a t speeds above approximately 40 mph (65 km/
h) .
Applies to vehicles with s ide ass ist*: if you acti­
vate a turn signa l when active lane assist is ready
a nd it classifies a lane change as critical bec ause
of veh icles traveling a longside you or approach ­
i ng you, there will be noticeable corrective steer­
i ng shortly before you leave the lane. This will at­
tempt to keep your vehicle in the lane.
Applies to vehicles without side assist* : the sys ­
tem does not warn when it is ready if you act ivate
the turn signal before crossing the lane marker
lin e. In this case, it assumes that you are chang­
in g lanes intent ionally.
Applies to vehicles with adaptive cruise contro l*:
there is no corrective steer ing or warnings if the
system recognizes a distinct passing maneuver.
If the conditions are met, congestion assist
switches on at speeds under approximately
40 mph (65 km/h)
¢page 104.
_& WARNING
-The system warns the driver that the vehicle
is leaving the lane using correct ive steering.
The driver is always responsible for 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 steering
wheel.
- Corrective steering may not occur in certain
situations, such as during heavy braking .
- There may be cases where the camera does
not recognize all lane marker lines. Correc­
tive steering can only take place on the side
of the vehicle where lane marker lines are
detected.
