of the vehicle when necessary, for example by ap-
plying the brakes.
— Ifa vehicle that was already detected @ turns
or changes lanes, the system will react to the
vehicle ahead of it (2).
— When driving into a curve > fig. 104 and out of
a curve, the system may react to a vehicle in the
adjacent 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 128, fig. 94.
— When driving around tight curves, a vehicle
driving ahead that was previously detected may
no longer be detected, and the adaptive cruise
assist may accelerate unexpectedly.
— 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.

Applies to: vehicles with adaptive cruise assist and lane guid-
ance

B8V-0692


Fig. 109 Turn signal lever: Lane guidance and lane depar-
ture warning button
Within the limits of the system, lane guidance
provides corrective steering to assist the driver
with keeping the vehicle in the center of the lane
as much as possible. This feature can be deacti-
vated.
Switching lane guidance on and off
Requirement: lane guidance must be preselected
in the MMI > page 151.
> To activate/deactivate the availability of the
lane guidance, press the button on the turn sig-
nal lever > fig. 109.
The system will assist the driver by providing cor-
rective steering only when adaptive cruise assist
is actively regulating and availability is switched
on.
Overview of displays and lane guidance
limitations
The indicator @9 in the Driver assistance display
indicates the availability of lane guidance
=> page 143, fig. 106.
© - Lane guidance is active.
&- Lane guidance is not active.
If the or indicator light turns on white on
at least one side, or the [J indicator light turns
on white in the Driver assistance display, then
lane guidance is not active. This may be due to
the following reasons:
— The necessary lane marker lines have not been
detected (for example, in a construction zone
146
or because the lines are obstructed by snow,
dirt, water, or lighting)
— The lane is too narrow or too wide
— The curve is too narrow
— The driver's hands are not on the steering
wheel
— Visibility is obstructed by a rise or dip.
— The turn signal was activated.
Steering intervention request
If no steering activity is detected or the steering
power from the system is not sufficient, the driv-
er steering intervention request will alert the
driver using audio and visual signals. Take over
the steering and keep your hands on the steering
wheel so that you will be ready to steer at any
time. The system will become inactive after a
short time and will only be active again later.
If the driver does not take over steering, adaptive
cruise assist will be canceled. If the vehicle is
equipped with emergency assist and it is ready to
function, it will be activated if possible
=> page 162.

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

@) 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.
— It is recommended to only switch on lane
guidance on well-constructed roads.
—The > fig. 109 button switches lane guid-
ance availability and the lane departure
warning on or off simultaneously, if lane
guidance is preset in the adaptive cruise as-
sist settings.

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.
