— If traffic signs are displayed on sign holders
with electronic signs
— If the traffic signs or the roadways have
changed, and the navigation data is no longer
up-to-date

Z\ WARNING
— Follow the safety precautions and respect
the limits of the assist systems, sensors,
and cameras > page 154.
— Under some circumstances, traffic sign rec-
ognition may not detect traffic signs correct-
ly or detect them at all. As a result, the sys-
tem may not display the correct speed limit
or any speed limit.
@) Tips
— Traffic sign recognition does not adapt your
vehicle's speed to match the speed Limit.

— The display in the instrument cluster is
based on the units of measurement used for
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 mph
or km/h, depending on the country.

Night vision assist
Applies to: vehicles with night vision assist
Night vision assist helps you when it is dark by
using an infrared camera to monitor the area in
front of your vehicle, within the limits of the sys-
tem. It can display objects up to a distance of ap-
proximately 1000 feet (300 m).
Pedestrian and wild animals are detected by
measuring the temperature difference between
the object and the background. Pedestrians and
wild animals will not be detected if the tempera-
ture difference is too small. The pedestrian and
wild animal marking feature is deactivated at
temperatures above approximately 77 °F (25 °C)
and when it is light outside.
The thermal image detected by the camera is dis-
played in the instrument cluster. Warm areas
generally appear lighter and cold areas appear
darker.
The camera for the night vision assist @)
= page 156 is located in the vehicle's radiator
grille. Make sure the night vision camera is not

Driver assistance

— When a route is planned using the naviga-
tion system*, then system displays messag-
es based on an assumed route. Without
route guidance, the system displays mes-
sages based on an assumed route.

pending on the selected Audi drive select*
mode and the selected gear. No messages
are displayed when in the "S" driving pro-
gram.
— Certain settings are stored automatically in
the active personal profile.
Predictive control
Applies to: vehicles with adaptive cruise assist and efficiency
assist

Fig. 124 Instrument cluster: speedometer: predictive con-
trol display
During predictive control), the adaptive cruise
assist uses data from the efficiency assist. The
system adapts the speed set in the adaptive
cruise assist to the speed limits that are detected
and the layout of the road. After that, the system
accelerates up to the speed that was set.
After switching on the ignition, the availability of
predictive control is indicated by a message when
the adaptive cruise assist is first activated.
Requirements
— The adaptive cruise assist must be actively reg-
ulating > page 173.
— The system can only react to speed limits that
are 20 mph (30 km/h) or higher.
Display in the speedometer
The display in the speedometer is not available in
all layouts*.

D_ This is not available in some countries.
@ The marking shows the set speed (regulated
speed that was set by the driver or by predic-
tive control).
@ The red band shows the difference between
the speed limit and the set speed that is set.
@ The gray band shows if 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 173, fig. 130.
Setting predictive control
You can switch off predictive control functions or
adjust them individually. The settings depend on
the vehicle equipment.
Applies to: MMI: Select on the home screen: VE-
HICLE > Driver assistance > (<2) > Adaptive
cruise assist > Predictive control.
Possible settings:
Set speed limit - Adjusts to speed limits. You can
also set With tolerance if desired. In this scenar-
io, you may fall below or exceed the set speed in
favor of increased efficiency.
Adjustment to curves along route - Can be
switched Off or be set individually from Slow to
Fast. The setting influences vehicle handling with
predictive control, for example the speed for
driving through curves.
Messages
rig 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

the systems 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
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 154.
— 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.

G) 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.
—If a 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.

YD In certain countries
170
— 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.
— Certain settings are stored automatically in
the active personal profile.
Adaptive cruise assist
General information
Applies to: vehicles with adaptive cruise assist
Depending on the vehicle equipment, the adap-
tive cruise assist may consist of the following
functions:
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 assist can
brake and accelerate your vehicle within the lim-
its of the system. On open roads with no traffic, it
functions like a cruise control system. The stored
speed is maintained. When approaching a vehicle
driving ahead, the adaptive cruise assist auto-
matically brakes to match that vehicle'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 assist ac-
celerates up to the set speed.
