Predictive control
(efficiency assist)
Description
Applies to: vehicles with Audi adaptive cruise control and pre·
dict ive efficiency assist
Fig. 122 Instrument cluster: predictive control
General information
The predictive control 1l uses the map informa·
tion from the navigation system in order to react
proactively when driving. Information from the
camera -based traffic sign recognition* is also ap·
plied to recognize traffic signs
r::!> page 109.
When coming up to areas with speed limits or
changes in the course of the road (such as curves,
inte rsections or traffic circles), the system brakes
automatically and then accelerates back up to
the set speed.
When adaptive cruise cont rol is switched off, the
system only provides notificat ions without con­
trolled intervent ions
r::!> page 112 .
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 ch ange the speed
using the lever
<:!> page 117 , fig . 117 .
Always switch off the predictive control in
the following situations:
- When increased attention is needed from the
driver .
- In poor we ather condit ions such as snow or
heavy rain .
- When driving on roads in poor condition.
l) This is no t a vail able in som e coun trie s.

Indicator in the instrument cluster display
When switching on the adaptive cruise control
for the first time, the message
ACC: 1111 + B ac­
tive
in the instr ument cluster indicates the avail­
ability of the predictive control.
The symbol appears when the system
i s regulating the speed to match a speed limit .
If
this is the case, the system is regulating a speed
of 50 mph (80 km/h). The speed is then taken
over by the adaptive cruise control. The speed in
the speedometer LED ring adjusts to the speed to
be maintained
r::!> page 115, fig. 116 . The ..

A WARNING
- Read the warnings on c> .& in General infor­
mation on page 114
and on r::!> .& in Descrip­
tion an page 109 .
-Pay attention to traffic and the area around
your vehicle when predictive control is
sw itched on. The driver is always responsi­
ble for assessing the traffic situation.
-There is an increase in the risk of an acci­
dent, because the system does not consider
"right of way" rules and also does not re-
spond to traffic lights.
._

-The system only considers traffic signs that
give a speed limit.
- The permitted speed can be exceeded if the
adaptation to a speed limit is incorrect. The dr iver is responsible for adhering to the per­
mitted speed.
- The speed at which a curve is driven through
does not necessarily match your own driving
style . Brake the vehicle yourself when need­
ed to reduce the r isk of a n accident .
(D Tips
-If a speed limit is detected, the stored
speed is also adjusted in the speedometer
L ED line when the adaptive cruise control is
not active .
- The adaptation by the system depends on
the driving mode set in drive select* .
- Switch ing off pred ictive control, for exam­
ple when dr iving in low traffic zones, does
not cause the adaptive cru ise control to
switch off.
-After switching on the ignit ion, the system
i nit ially adjusts to a speed of 80 mph
(130 km/h) when driv ing onto h ighways
wi thou t a speed limit . Then the system ad­
ju sts to the last speed stored by the driver.
- There is no adaptation to speed limits when
driv ing thro ugh highway interchanges and
when driving on o r off the expressway.
- There is no predictive cont rol at speed limits
u nder 20 mph (30 km/h).
- If a speed limit is only detected by the cam­
era and the actual speed is s ignificantly
h igher, then the speed limit will blink i n the
display unti l you have reached the requ ired
speed
~ page 110 .
-Incorrect values from the camera-based
traffic sign recognition* or outdated naviga ­
tion system map data can lead to incorrect
or implausible control.
- When route guidance is switched on, the
system adapts to the route provided by the navigation system. Driving w ithout route
guidance or leaving a route can resu lt in im­
plaus ible control.
A ss is ta nce syst ems
-The system switches off when outside of a
road system that is recorded in the naviga­
tion system map data .

Audi pre sense
Introduction
App lies to: vehicles with Audi pre sense
Within the limits of the system, the pre sense
functions can initiate measures in particularly
dangerous situations to protect the vehicle pas­
sengers and other road users.
- Due to the interlinking of various vehicle sys­
tems, critical driving situations can be detected by
pre sense basic and measures for preventa ­
t ive occupant protection are can be initiated .
- The
pre sense front system uses the data from
the adaptive cruise control* radar sensors and
the camera to calculate the probability of a col­
li sion. Within the limits of
the system, an im­
pending collision with vehicles can be detected
in both urban and rural speed ranges. In this
case, the system warns the driver visually,
acoustically and with a jerk on the brakes if nec­
essary. If needed, it can initiat e a partial or full
deceleration to reduce the collision speed or to
avoid the collision under certain circumstances .
I n conjunction with pre sense basic/rear, the
front safety belts are also revers ibly tensioned
when needed . The pre sense front is also active
when adapt ive cruise control* is switched off .
-Pre sense rear contains pre sense basic func­
tions. It uses the data from the side assist* ra­
dar sensors and calcu lates withi n the limits of
the system the probability of a rear end coll i­
sion with the vehicle beh ind you. Pre sense rear
is also active when side assist* is switched
off.
- Within the limits of the system, pre sense city
uses the camera data and can detect an im­
pending collision with vehicles and pedestrians.
In this case, the system warns the dr iver visual­
ly, acoustically and with a jerk on the brakes if
necessary. If needed, it can initiate a full decel­
eration to reduce the collision speed or to avoid
Assistance systems
the collision under certain circumstances. In
conjunction with pre sense basic/rear, the front
safety belts are a lso reversibly tens ioned when
needed .
A WARNING
Read the genera l information in c:>&. in Gen­
eral information on page 114,
c:> &. in Gener­
al information on page 135.
(D Tips
- Certain pre sense functions switch off when driving in reverse.
- The pre sense functions may not be availa­ ble if there is a malfunction in the ESC sys­
tem or the airbag control module.
- Note that the reversible belt tensioner on
the front passenger's side deactivates when
the front passenger's airbag is deactivated .
- Switch the pre sense
off when you a re not
using public streets or when loading the ve­
hicle onto a vehicle carrier, tra in, sh ip or
other type of transportat ion. This can pre­
vent an undesired inte rvention from
the pre
sense system.
Audi pre sense basic
Description
Applies to : vehicles with Audi pre sense basic
The pre sense basic functions are activated at a
speed of approx imately 20 mph (30 km/h) or
higher .
The following functions can be triggered under certain conditions within the limits of the sys­
tem:
- Tensioning of the safety belts (for examp le,

(30 km/h) and 90 mph (150 km/h).
Tu rn as sist
When starting to drive a nd up to speeds of maxi­
mum
6 mph (10 km/h), the turn assist uses a
braking intervention to prevent your vehicle from
colliding with an oncoming vehicle when tu rning
left or right (available in certain countries). The
braking intervention causes your vehicle to stay
in its lane.
A WARNING
- Pre sense front cannot overcome the laws of
physics . It is a system des igned to assist and
it cannot prevent a collision in every circum­
stance. The drive r must always i nte rvene.
T he driver is always responsib le for b raking
at the correct time. Do not let the increased
safety provided tempt you into taking risks .
This cou ld increase your risk of a collision .
- The system can deploy incorrectly due to
system-specific limits .
- Please note that the sensors and the camera
do not always detect all objects or lane
markings. This increases the risk of an acci­
dent .
- Pre sense front does not react to people, an­
imals or objects that are cross ing the veh i­
cle's path or that are difficu lt to
detect¢ &
in General information on page 114 .
-Reflective objects such as guard rails or the
entrance to a tunnel, heavy rain and ice can
affect the function of the radar sensors and
the system's ability to detect a collis ion risk .
