cially responsible for braking, steering,
starting to drive, and controlling the speed
and the distance from other vehicles.
— Turn on the adaptive cruise assist only if the
surrounding conditions permit it. Always
adapt your driving style to the current visu-
al, weather, road, and traffic conditions.
— Switch the adaptive cruise assist off tempo-
rarily when driving in turning lanes or high-
way exits. This prevents the vehicle from ac-
celerating to the stored speed when in these
situations.
— If you press the [SET] button @) when driv-
ing at speeds below 20 mph (30 km/h),
then the minimum possible speed will be
set. If no vehicle is detected ahead of you,
the vehicle will accelerate up to that speed.




ZX WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 127.
— The adaptive cruise assist is only an assist
system, and the driver is still responsible for

controlling the vehicle. The driver is espe-

@ 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.

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.
The following distances can be set:
