Instrument cluster: distance warning
General information
At speeds above approximately 40 mph (65
km/h), this function measures the distance to the
vehicle ahead as time. If the distance falls below
the warning threshold, the system warns you of
the hazard with the [J indicator light.
Image in the Driver assistance display
Applies to: vehicles with adaptive cruise assist
The display only appears if the Driver assistance
display is selected on the on-board computer
=> page 16 and the adaptive cruise assist is not
actively controlling the vehicle.
@ Detected vehicle driving ahead
@ Use the markings to help you estimate the
distance to an obstacle. Each marking repre-
sents approximately one second.
@) Set warning threshold. Depending on the set-
tings, the display will be colored in from the
bottom to the top.
@ You will be warned as soon as you fall below
the set distance.
Adjusting the distance warning
The system can be switched on and off in the
MMI page 157.
You can adjust the distance warning threshold to
your preferences. The settings depend on the ve-
hicle equipment.

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 156, fig. 117 and try to turn on
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.
G) Tips
— The driver is always responsible for adhering
to the regulations applicable in the country
where the vehicle is being operated.
— You may fall below the warning threshold
briefly when passing or when quickly ap-
proaching a vehicle driving ahead. There is
no warning in this scenario. A warning is giv-
en only if you fall below the warning thresh-
old for an extended period of time.

Turn assist
Applies to: vehicles with turn assist
When your vehicle is turning
The turn assist can assist you with a braking in-
tervention when starting to drive or when driving
slowly, to reduce the risk of your vehicle colliding
with an oncoming vehicle when you are making a
left turn). The braking intervention causes your
vehicle to stay in its lane. The function is only
available when the turn signal is turned on and at
speeds up to maximum of 6 mph (10 km/h).

ZA WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 154.
— The turn assist does not react to pedes-
trians, animals, crossing objects, and ob-
jects not detected as vehicles.
@ Tips
— System functions may not be available if the
ESC is limited or switched off, or if there is a
malfunction.
— An indicator in the instrument cluster will
inform you when there is an intervention.
Adjusting Audi pre sense
Applies to: vehicles with Audi pre sense

The system can be switched on and off in the
MMI & page 157.
You can adjust the Audi pre sense functions to
your preferences. The settings depend on the ve-
hicle equipment.
> Applies to MMI: Select on the home screen: VE-
HICLE > Driver assistance > (<3) > Audi pre

Prewarning~ - The prewarning can be switched
off or the Audi pre sense warning time can be set
(Early/Medium/Late).
Set the warning time for the early warning to
Early at first. If you feel that the prewarnings ap-
pear too early, then set the warning time to Me-
dium. The Late warning time should only be set
in special circumstances.
@) Tips
— Switch Audi pre sense off when you are not
using public streets, when loading the vehi-
cle onto a vehicle carrier, train, ship, or oth-
er type of transportation, or when towing
the vehicle. This can help to prevent an un-
desired intervention from the Audi pre
sense system.
— If the system is switched off, it switches on
again automatically once the ignition is
switched on again”).
— Certain settings are stored automatically in
the active personal profile.

Fig. 144 Instrument cluster: directional display from the
intersection assistant
General information
The intersection assistant can warn the driver of
approaching cross traffic in complex intersections
> fig. 143.
The system monitors intersections and exit
ramps using the sensors installed in the vehicle
that detect the front and side areas around the
vehicle. Moving objects that are approaching
from behind, such as cars, are detected within
the limits of the system > A\. The system can al-
so warn the driver of a potential collision with de-
tected approaching cross traffic in intersections
and exit ramps with poor visibility.
Requirements for using the intersection
assistant:
— The speed must not be higher than approxi-
mately 18 mph (30 km/h).
— The “D” gear is selected.
Displays, warnings, and braking
— Display: the red arrow (@) can indicate the direc-
tion from which the cross traffic is approaching.
The indicator in the upper display only appears
when the parking aid is activated. For vehicles
with peripheral cameras only in the Front and
Front corner camera views. The display only ap-
pears in the instrument cluster > fig. 144 when
the Driver assistance display is open in the on-
board computer > page 16.
— Warnings: the message Cross traffic! © can
warn you of critical cross traffic when driving
forward. There may also be an audible signal.
— Automatic brake activation: if you do not react
to a warning, a brief braking by the system can
warn you of a potential collision with an ap-
proaching object when driving forward at
speeds up to approximately 6 mph (10 km/h).
Switching the intersection assistant on and
off
— The system can be switched on and off in the
MMI & page 157.
Messages

Applies to: vehicles with parking system plus

Fig. 146 Upper display: distance indicator
If the sensors detect an obstacle, audible and vis-
ual signals will warn you.
Visual warnings
The visual warnings in the upper display help you
to detect the critical vehicle area and to estimate
the distance to an obstacle.
Red segments (4) show detected obstacles that
are in your vehicle's path. The red lines (2) mark
the expected direction of travel based on the
steering angle. A white segment (3) indicates a
detected obstacle that is outside of the vehicle's
path. The closer your vehicle comes to the obsta-
cle, the closer the segments will move to the ve-
hicle. The collision area has been reached when
the next to last segment is displayed. Obstacles
in the collision area, including those outside of
the vehicle's path, are shown in red. Do not con-
tinue driving farther.
Audio signals
The closer your vehicle gets to a detected obsta-
cle, the shorter the time between the audible sig-
nals. A continuous tone sounds when an obstacle
is less than approximately 1 foot (0.30 m) away
from the front or rear of the vehicle. Do not con-
tinue driving forward or in reverse >(@).
> To deactivate audio signals while parking, press
«Jin the upper display. The audio signals will be
automatically activated again the next time the
parking system is activated.
Adjusting the volume
You can adjust the volume to your preferences.
The settings depend on the vehicle equipment.
> Applies to: MMI: Select on the home screen:
VEHICLE > Parking aid. Or
> Press |---| in the upper display when the parking
system is active.


Possible settings:
Front volume - Volume for the front area.
Rear volume - Volume for the rear area.
Entertainment fader - The volume of the audio/
video source is lowered when the parking system
is activated.
The new level is demonstrated briefly* when the
volume is adjusted.
Error messages
If P4 appears, the sensor in the respective area
or the speaker is faulty. Drive immediately to an
authorized Audi dealer or authorized Audi Service
Facility to have the malfunction repaired.
If Avis displayed in the MMI, the ultrasonic sen-
sor indicated is icy or dirty. Clean the area in front
of the sensors > page 156. >
