Fig. 110 Instrument cluster: speedometer: predictive con-
trol display
With predictive control, efficiency assist adapts
the set speed in adaptive cruise control @ based
on detected speed limits and the upcoming
route. Once the system no longer detects any in-
cidents, adaptive cruise control will accelerate
back up to the last speed that the driver set. Af-
ter switching on the ignition, the availability of
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 141, Situa-
tion symbols.
Requirements
— Predictive control is switched on in the MMI
> page 151.
— The adaptive cruise assist must be actively reg-
ulating > page 144.
— The system can only react to speed limits that
are 20 mph (30 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).
® ® The red band shows the difference between
the speed limit and the set speed that is set.
The marked 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 144, fig. 108.
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 129 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.

Z\ WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 127.
— 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
147
>

Driver assistance

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.
— You may temporarily fall below or exceed
the set speed due to recuperation.
— 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 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 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.

to maintain a sufficient distance to the vehicle
ahead. The system will warn you of the hazard
with the A indicator light and the message Dis-
tance!. An audio signal will also sound.

Driver assistance

Early warning/acute warning
The system can recognize various dangerous sit-
uations. The early warning occurs if:
— A vehicle driving ahead brakes suddenly
— Your own vehicle approaches a vehicle in front
of you that is traveling at a significantly slower
speed or that is stationary
—A pedestrian or cyclist!) is standing in the lane
or is moving into the lane
The message Audi pre sense [J and a warning
tone will warn you about the danger.
The brakes may also be applied as an acute warn-
ing when there is an impending collision. You will
also be warned by an indicator in the instrument
cluster display. When this warning occurs, it may
only be possible to avoid a collision by swerving
or braking strongly.
Automatic deceleration
If you do not react to the acute warning, Audi pre
sense front can brake the vehicle to a full stop
within the limits of the system ). This reduces
the vehicle speed in the event of a collision.
Automatic braking force increase
If Audi pre sense determines that you are not
braking strongly enough when a collision is immi-
nent, it can increase the braking force based on
the situation.
Take-over
If the message ao Please take over! appears, the
vehicle has been braked to a stop by Audi pre
sense and you must resume control of the vehi-
cle.

ZA WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 127.

tervene. 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.
— Audi pre sense front does not react to cer-
tain objects, such as animals, crossing or on-
coming vehicles, bars, railings, or railcars.
— Audi pre sense front may be limited or un-
available when driving in curves.
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Store objects securely while
driving.
—In trailer mode, the braking behavior of the
trailer can be different than usual during au-
tomatic braking.
(i) Tips
Certain pre sense front functions are switched
off when the hill descent assist is actively con-
trolling the vehicle.
Audi pre sense rear
Applies to: vehicles with Audi pre sense rear

Within the limits of the system, Audi pre sense
rear uses data from radar sensors in the rear area
of the vehicle and calculates the probability of a
rear-end collision with the vehicle behind you.
