@) Tips
— The functions depend on the navigation da-
ta* being up-to-date and correct identifica-
tion by the traffic sign recognition*.
— The system only detects traffic signs that
specify a speed limit.
— The display in the instrument cluster is
based on the units of measurement used for
138
speed in the country where the vehicle is be-
ing operated. As a result, a display of 50 in
the instrument cluster can mean either
km/h or mph, depending on the country.
— Except for the road network, which is re-
corded in the navigation system’s map infor-
mation, certain functions may not be availa-
ble.
— Certain settings are automatically stored
and assigned to the remote control key be-
ing used.

uation symbols.
Requirements
— The cruise control system* or Audi adaptive
cruise control* must not be actively regulating.
— The vehicle speed must be at least 20 mph
(30 km/h).
—The remaining distance until the situation is
reached must be large enough to allow the sys-
tem to react to the situation.
— The automatic transmission is not in the “S”
driving program.

Audi adaptive cruise
control
General information
Applies to: vehicles with Audi adaptive cruise control
Depending on vehicle equipment, Audi adaptive
cruise control may consist of the following func-
tions:
Within the limits of the system, the adaptive
speed and distance control assists the driver in
controlling the speed and the set distance to the
vehicle driving ahead. If the system detects a ve-
hicle driving ahead, the adaptive cruise control
can brake and accelerate your vehicle within the
limits of the system. On open roads with no traf-
fic, it functions like a cruise control system. The
stored speed is maintained. When approaching a
vehicle driving ahead, the adaptive cruise control
system automatically brakes to match that vehi-
cle's speed and then maintains the set distance
as much as possible. As soon as the system does
not detect a vehicle driving ahead, adaptive
cruise control accelerates up to the stored speed.
In stop-and-go traffic, the vehicle may brake to a
full stop and then may also start driving again
automatically under certain conditions.
Applies to: vehicles with traffic jam assist: In
traffic jams or in stop-and-go traffic, the traffic
jam assist can assist the driver to stay within the
lane detected by the system > page 147.
Applies to: vehicles with efficiency assist: Predic-
tive control can adjust the set speed based on
traffic and road conditions > page 142.
ZA WARNING
Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 126.
) Tips
The system complies with United States FCC
regulations and ISED regulations > page 297.
Applies to: vehicles with Audi adaptive cruise control
Fig. 113 Example: driving into a curve
In some situations, the adaptive cruise control
function is limited and you must assume control
of the vehicle when necessary, for example by ap-
plying the brakes.
— When driving into a curve > fig. 113 and out of
a curve, the system may react to a vehicle in the
neighboring lane and apply the brakes. You can
override the system by pressing the accelerator
pedal briefly.
— The system works with the various sensors and
cameras in the vehicle. Vehicles can only be de-
tected once they are within the area and range
covered by the sensors > page 127, fig. 106.
— When driving around tight curves, a vehicle
driving ahead that was previously detected may
no longer be detected, and the system may ac-
celerate unexpectedly. >
139
Page 142 of 318
Driver assistance
— The system does not react to a stationary vehi-
cle in the same lane if it expects that you can
easily drive around the stationary vehicle by
turning the steering wheel.
— The system cannot react to stationary objects,
such as vehicles at the end of a traffic jam, es-
pecially when traveling at high speeds.
— 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 difficult to detect, such as mo-
torcycles, vehicles with high ground clearance,
or vehicles with an overhanging load, may be
detected late or not detected at all.
— The system does not respond to people, ani-
mals, or objects that are crossing or approach-
ing from the opposite direction.

ZA\ WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 126.
— The activated adaptive cruise control is only
an assist system, and the driver is still re-
sponsible for controlling the vehicle. The
driver is especially responsible for braking,
steering, starting to drive, and controlling
the speed and the distance from other
vehicles.
— Turn on the adaptive cruise control only if
the surrounding conditions permit it. Always
adapt your driving style to the current visu-
al, weather, road, and traffic conditions.
— Switch adaptive cruise control off temporari-
ly when driving in turning lanes, on express-
way exits or in construction zones. This pre-
vents the vehicle from accelerating to the
stored speed when in these situations.
— If you press the [SET] button @) when driv-
ing at speeds below 15 mph (20 km/h)»,
the minimum possible speed that the sys-
tem can maintain will be set. If no vehicle is
detected ahead of you, the vehicle will accel-
erate up to that speed.
@) Tips
— Always keep your hands on the steering
wheel so you can be ready to steer at any
time. The driver is always responsible for
adhering to the regulations applicable in
the country where the vehicle is being oper-
ated.
D_ Analog instrument cluster: 20 mph (30 km/h)
142
— If you switch the ignition or the adaptive
cruise control system off, the set speed is
erased for safety reasons.
— When adaptive cruise control is switched
on, the ESC and ASR automatically switch
on.
— The system cannot be switched off or it may
be interrupted if the road exceeds the maxi-
mum possible grade for safe operation.
Predictive control
Applies to: vehicles with Audi adaptive cruise control and effi-
ciency assist
With predictive control, efficiency assist adapts
the set speed in adaptive cruise control @
=> page 140, fig. 114 based on detected speed
limits and the upcoming route. Once the system
no longer detects any incidents ahead, adaptive
cruise control will accelerate back up to the last
speed that the driver set. After switching on the
ignition, the availability of predictive control is
indicated by a message when the adaptive cruise
control is first activated.
Incident symbols indicate the situation to which
predictive control is reacting > page 138, Situa-
tion symbols.
Requirements
— Predictive control is switched on in the MMI
=> page 146.
— Adaptive cruise control is actively regulating
=> page 141.
— The system can only react to speed limits that
are 15 mph (20 km/h)” or higher.
Overriding control
The driver can override the predictive control to
the route ahead at any time by pressing the ac-
celerator or brake pedal. If the system changes
the vehicle speed to adapt to speed limits, you
can change the speed using the lever
=> page 141, fig. 117.

Messages
If and a message with Predictive control is
displayed when there is a malfunction, the effi-
ciency assist functions are unavailable or limited.
A message that indicates the cause and possible
solution may appear with some displays. The
weather conditions may be too poor or a sensor
may be covered. Clean the area in front of the
sensors > page 128 and try to turn on the sys-
tems again later.
If the malfunction remains, drive to an author-
ized Audi dealer or authorized Audi Service Facili-
ty immediately to have the malfunction correct-
ed.
ZA WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 126.
— Pay attention to traffic and the area around
your vehicle when predictive control is
switched on. The driver is always responsible
for assessing the traffic situation.
— The system does not consider “right of way”
rules and does not respond to traffic lights,
so lack of driver attention in these situations
can increase the risk of an accident.
— The speed when driving through curves may
be different from what you as a driver would
do or may not be suitable for the weather
and road conditions. If necessary, apply the
brakes and reduce the selected speed to be
maintained in the Adjustment to curves
along route setting to reduce the risk of an
accident.
@) Tips
— Predictive control can exceed or drop below
the maximum permitted speed. The driver
is responsible for adhering to the permitted
speed limit.
— The traffic signs on the road always take pri-
ority over the display. The driver is always
responsible for adhering to the regulations
D In certain countries
applicable in the country where the vehicle
is being operated.
— Ifa speed limit is detected, the marking @
= page 140 of the set speed limit will be ad-
justed even if Audi adaptive cruise control is
not actively regulating.
— Control by the system depends on which
adaptive cruise control driving program is
set or on the selected Audi drive select*
mode.
— After switching on the ignition and first
driving onto a freeway or similar road with-
out a speed limit, the system will regulate
the speed to 80 mph (130 km/h). Then
the system adjusts to the last speed set by
the driver.
— There is no adaptation to speed limits when
driving through highway interchanges and
when driving on or off the expressway.
— The system can fail to provide control or the
control may be faulty if the values from the
camera-based traffic sign recognition* are
incorrect or the navigation system map data
is outdated.
— 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
faulty control.

the indicator lights.
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 vehicle driving ahead accelerates,
then the adaptive cruise control will accelerate
up to the speed that you have set.
