Driver assistance

predictive control is indicated by a message when
the adaptive cruise assist is first activated.
Incident symbols indicate the situation to which
predictive control is reacting > page 137, Situa-
tion symbols.
Requirements
— Predictive control is switched on in the MMI
=> page 146.
— The adaptive cruise assist must be actively reg-
ulating > page 140.
— The system can only react to speed limits that
are 15 mph (20 km/h)» or higher.
Display in the speedometer
The display depends on vehicle equipment and is
not available in all layouts”.
@ The marking shows the set speed (regulated
speed that was set by the driver or by predic-
tive control).
@ Audi virtual cockpit: The red band shows the
difference between the speed limit and the
set speed.
® Audi virtual cockpit: The gray band shows the
amount the vehicle speed is planned to drop
below the set speed due to the road layout.
Overriding control
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 140, fig. 102.
Messages
If and a message with Adaptive cruise assist:
Predictive control is displayed when there is a
malfunction, the efficiency 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 124 and try to turn the system on
again later.

) Analog instrument cluster: 20 mph (30 km/h)
If the malfunction remains, drive to an author-
ized Audi dealer or authorized Audi Service Facili-
ty immediately to have the malfunction correct-
ed.

A WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 122.
— 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
applicable in the country where the vehicle
is being operated.
— Ifa speed limit is detected, the marking @
of the set speed limit will be adjusted even
if the adaptive cruise assist is not actively
regulating.
— Control by the system depends on which
adaptive cruise assist 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

143

Driver assistance

without a speed limit, the system will regu-
late 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.

fig. 100. The display matches the functions of
the indicator lights.
When approaching a vehicle driving ahead, the
adaptive cruise assist brakes to the set speed and
then maintains the set distance. If the vehicle
driving ahead accelerates, then the adaptive
cruise assist will also accelerate up to the speed
that you have set.
The following distances can be set:

Meaning

The time between is approximately 1
second. This setting corresponds toa
distance of approximately 92 feet (28
m) when traveling at 62 mph (100
km/h).
The time between is approximately 1.3
seconds. This setting corresponds toa
distance of approximately 118 feet
(100 m) when traveling at 62 mph
(36 m/h).
The time between is approximately 1.8
seconds. This setting meets the general
recommendation of “half the speed
shown on the speedometer”. This cor-
responds to a distance of approximate-
ly 164 feet (50 m) when traveling at
62 mph (100 km/h).
The time between is approximately 2.4
seconds. This setting corresponds toa
distance of approximately 219 feet
(100 m) when traveling at 62 mph
(67 m/h).
The time between is approximately 3.6
seconds. This setting corresponds toa
distance of approximately 328 feet
(100 m) when traveling at 62 mph
(100 m/h).
