Driver assistance

@ 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 139, fig. 101.
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 123 and try to turn the system on
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.


— 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.


ZA\ WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 121.
— 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.


D_Incertain countries.

@) 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.
— Ifa 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.
— 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.

If you adjust the speed, you must also change the
time gap to the vehicle driving ahead. The higher
the speed, the greater the distance that is need-
ed.
> Tap the rocker switch to display the distance
that is currently set.
> To increase or decrease the distance in incre-
ments, tap the switch again toward @) or ().
The newly-set distance will be shown briefly, for
example with the indicator light. In the Driv-
er assistance display, a graphic display is shown
instead of the indicator lights > page 138,
fig. 99. The display matches the functions of 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:

Meaning

The time between is approximately 1
second. This setting corresponds to a
distance of approximately 92 feet (28
m) when traveling at 62 mph (100
km/h).
The time between is approximately 1.3
seconds. This setting corresponds toa
distance of approximately 118 feet
(100 m) when traveling at 62 mph
(36 m/h).
The time between is approximately 1.8
seconds. This setting meets the general
recommendation of “half the speed
shown on the speedometer”. This cor-
responds to a distance of approximate-
ly 164 feet (SO m) when traveling at
62 mph (100 km/h).
The time between is approximately 2.4
seconds. This setting corresponds toa
distance of approximately 219 feet
(100 m) when traveling at 62 mph
(67 m/h).
The time between is approximately 3.6
seconds. This setting corresponds toa
distance of approximately 328 feet
(100 m) when traveling at 62 mph
(100 m/h).

Audi pre sense
Introduction
Applies to: vehicles with Audi pre sense
Within the limits of the system, the Audi pre
sense functions can initiate measures in certain
driving situations to protect the vehicle occu-
pants and other road users. Depending on the ve-
hicle equipment, various Audi pre sense systems
may
be installed:
— Audi pre sense basic can react during emergen-
cy and dangerous braking maneuvers and un-
stable driving situations (such as oversteering
or understeering).
— Audi pre sense front) can detect an impending
frontal impact and react with warnings, braking
interventions, and preemptive safety measures
for the vehicle occupants.
— Audi pre sense rear monitors the rear traffic
behind your vehicle and can react to an impend-
ing rear impact.
— Audi pre sense side can detect an impending
side impact from cross-traffic and vehicles com-
ing from the side, and can initiate preemptive
safety measures.
— The swerve assist can help you to steer the ve-
hicle around an obstacle during an evasive ma-
neuver that is detected as critical.
— The turn assist can detect vehicles in the oppo-
site lane as critical during a turning maneuver
and react with braking maneuvers.

may only be able to avoid a collision by swerving
or braking strongly.
Automatic braking force increase
If there is an impending collision and you are not
applying the brakes enough, the braking force
may be increased, depending on the situation.
Automatic braking
If you do not react to the acute warning, the sys-
tem may apply the brakes with strong braking
force within the limits of the system in order to
reduce the speed of impact in the event of a colli-
sion.
If the brakes were applied until the vehicle stop-
ped, © Please take over! will appear in the in-
strument cluster and you must take over control
of the vehicle.

ZA WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 121.
— Audi pre sense front cannot overcome natu-
ral physical laws. It is a system designed to
assist and it cannot prevent a collision in ev-
ery circumstance. The driver must always in-
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.

@) 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 at the rear cor-
ners of the vehicle and calculates the probability
of a rear-end collision with the vehicle behind
you.
Audi pre sense preemptive safety measures can
be initiated if the risk of a collision with the vehi-
cle behind you is detected.

Z\ WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 121.
— Audi pre sense rear does not react to pedes-
trians, animals, crossing objects, and ob-
jects not detected as vehicles.
@) Tips
— Audi pre sense rear functions switch off
when trailer mode is detected. There is no
guarantee the functions will switch off
when using a retrofitted trailer hitch.
— Audi pre sense rear functions may also
switch off if there is a malfunction in the
side assist system.
Audi pre sense side
Applies to: vehicles with Audi pre sense side

Within the limits of the system, Audi pre sense
can warn about impending collisions with cross-
traffic and vehicles approaching from the side,
and trigger Audi pre sense preemptive safety
measures.
The system uses additional sensors in the front
and rear areas and is active at speeds up to ap-
proximately 35 mph (60 km/h).
