Predictive control
(efficiency assist)
Description
A pp lies to: ve hicles with Audi adaptive cruise co ntro l an d pr e·
di ctive efficiency assist
Fig. 118 Instrument cluster: pred ictive control
General information
The predictive control 1l uses the map informa­
tion from the navigation system in order to react
proact ively when driv ing. Information from the
camera-based traffic sign recognition* is also ap­ plied to recognize traffic signs
<:!)page 104.
When coming up to areas with speed limits or
changes in the course of the road (such as curves,
intersections or traffic circles), the system brakes
automatically and then accelerates back up to
the set speed .
When adaptive cruise control is switched off, the
system only provides notifications without con­
trolled
interventions ¢ page 107.
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 112, fig. 113 .
Always switch off the predictive control in
the following situations:
- When increased attention is needed from the
driver .
- In poor weather conditions such as snow or
heavy rain.

tive
in the instrument cluster indicates the avail·
ability of the predictive control.
T he symbol appears when the system
is regulating the speed to match a speed limit . If
this is the case, the system is reg ulating 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

A WARNING
- Read the warnings on ¢.&. in General infor­
mation on page 109
and on¢ .&. in Descrip­
tion on page 104 .
- Pay attention to traffic and the area around
your veh icle when predictive control is
switched 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. ._.
115

Ass is tance sy stems
-The system only considers traffic s igns that
give a speed limit.
-The permitted speed can be exceeded if the
adaptation to a speed limit is incorrect. The
driver is responsible for adhering to the per­
mitted speed .
-The speed at which a curve is driven through
does not necessarily match your own dr iving
sty le . Brake the vehicle yourself when need­
ed to reduce the risk of a n accident.
(D Tips
-If a speed limit is detected, the stored
speed is also adjusted in the speedometer
LED line when the adaptive cruise control is
not act ive.
-The adaptation by the system depends on
the driving mode set in drive select* .
-Switching off pred ictive control , for exam­
ple when dr iv ing in low traffic zones, does
not ca use the adaptive cru ise control to
switc h off .
-After switching on the ignit ion, the system
i nit ially adj usts to a speed of 80 mph
(130 km/h) when driving onto highways
without a spee d limit . T he n the system ad­
ju sts to the last speed stored by the driver.
- T here is no adapt ation to speed limits when
driv ing through highway inte rchanges an d
when d riving on o r off the ex pres sway.
- T here is no pre dic tive con trol at speed limits
u nder 20 mph (30 km/h).
- If a speed limit is only detected by the cam­
e ra and the actual speed is s ignific antly
higher, the n the speed limit will bli nk i n t he
dis play u nti l you have reached the re qui red
speed
¢ page 105 .
-Incorrect v alues from the camera -based
traffic sign recognition* or outdated naviga­
tion system map data can lead to incorrect
or implausible contro l.
- When route guidance is switched o n, the
system adapts to the route provided by the
navigation system. Driving without route
g uidance or leaving a route can resu lt in im­
plaus ible control.

-T he system switches of f when ou tside of a
road system that is recorded in the naviga­
t ion system map data .

jam assist can help to keep the vehicle within a lane calculated by the system. W ith in the lim its
of the system, the system controls the steering
automatically when adapt ive cruise control is
switched on . Since traffic jam assist is only an as­
sist system, the driver must always keep his or
her hands on the steer ing whee l and be ready to
steer. The d rive r ca n override the control at any
time by actively steering.
The system is designed for driv ing on express­
ways and highways.

Audi pre sense front
Description
Applies to: veh icles with Audi adaptive cruise control
Within the limits of the system, pre sense front
can warn you of impending collisions and initiate
the corresponding braking maneuvers or the sup­ porting measures when avoiding a collision .
If detected in time, the system can rank the dan­
gerous situation as critical if a vehicle driving
ahead brakes suddenly, if your own vehicle is ap­
proaching a significantly slower vehicle at high
speed or when there is an oncoming vehicle dur­
in g a turning maneuver .
If detection is not possible, then pre sense front
does not react .
Warnings
Applies to: ve hicles with Audi adaptive cruise control
Fig. 122 In strument cluste r: approac h warning
General information
The system recognizes various dangerous situa­
tions . The
early warning occurs if:
-a vehicle driving ahead brakes suddenly,
-your own vehicle approaches a significantly
a s lower vehicle or stationary vehicle in the direc-co
;::; tion of travel. ,....
N .... 0 0

Assistance systems
When this warning occurs, it may only be possi­
ble to avoid a collision by swerving or braking
strongly. The message
Audi pre sense.
¢ fig. 122 and a warning tone will warn you
about the danger .
If you do not react enough or not at all to a dan­
gerous situation that was detected by the sys­
tem, pre sense front provides assistance by ap­ plying the brakes .
If a collision is imminent, the system will first
provide an
acute warning by braking sharply. You
will also warned by an indicator in the instrument
cluster
display¢ fig. 122. If you do not react to
the acute warning, pre sense front can brake with i ncreasing fo rce within the limits of the
system
1>. This reduces the vehicle speed in the
event of a collision. At low vehicle speeds, pre
sense front can in itiate a complete deceleration
shortly before a collision with a vehicle driving
ahead
l). If pre sense front determines that you
are not braking strongly enough when a collision
is imminent, it can increase the braking force.
T he following functions trigger in conjunction
with pre sense basic/rear at corresponding vehi ­
cle speeds:
-Reversible tensioning of the front safety belts.
-Closing the windows and sunroof* .
-Inflating the side bolsters* on the seat back-
rest .
Audi drive select*: depending on the mode se­ lected, the reversible belt tensioner, the closing
of the w indows and sunroof*, and the inflating of
the side bolsters* on the seat backrest may not be active.
Evasive steering support
Evasive steering support helps you to steer the
vehicle around an obstacle in a critical situation .
If you avo id an obstacle after the acute warning,
then the evasive steer ing support ass ists you by
applying slight stee ring adjustment to correct
.,.
121

Ass is tan ce sys tems
your steering whee l ang le as long as you are ac­
tively steering. Evasive steering support is availa­
b le at speeds between approximately 20 mph
(30 km/h) and 90 mph (150 km/h).
Tu rn assist
When start ing to drive and 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 turning
left or right (available in certain countries). The
braking intervent ion 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 driver must always i ntervene.
T he driver is always responsib le 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.
- 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 ob jects that are crossing the veh i­
cle's path or that are difficu lt to
detect¢ .&.
in General information on page 109.
-Reflective objects such as guard rails or the
entrance to a tunnel, heavy rain and ice can
affect the fu nction of the radar sensors and
the system's ability to detect a coll is ion risk .
(D Note
The sensors can be displaced by impacts or
damage to the bumper, whee l housing and
underbody. Pre sense front can be impa ired
by this. Have an authorized Aud i dealer or au­
thorized Audi Service Fac ility check their func­
tion.

(D Tips
- You can cancel the braking with increas ing
force that is initiated by the system by bra k­
ing yourself, by acce lerating not iceably or
by swerving.
- Keep in mind that pre sense front can brake
unexpectedly. Always secure any cargo or
objects that you are transporting to reduce
the risk of damage or injury.

Audi active lane assist
Description
Applies to: ve hicles wit h Aud i act ive lane ass ist
Active lane assist (lane departure warning) de­
tects lane marker lines within the limits of the
system using a camera in the windshield . If you
are approach ing a detected lane marker line and
it appears likely that you will leave the lane, the
system w ill wa rn you w it h corre ct ive steer ing .
You can overr ide th is steering at any time . If yo u
pass over a line, the steer ing whee l wi ll vibrate
lightly. In order for this warning vibration to oc ­
cur, it must first be switched on in the Infotain­
ment system. Active lane assist is ready for oper­
ation when the lane marker line is detected on at least one side of the vehicle.
The system is designed for driving on express ­
ways and highways and therefore only activates at speeds above approximately 40 mph (6S km/
h).
Applies to: vehicles with side assist: if you acti­
vate a turn signal when active lane assist is ready
and it classif ies a lane change as critical because
of vehicles traveling alongside you or approach­ ing you, there w ill be not iceable correct ive steer­
i ng shortly before you leave the lane . This will at­
tempt to keep your veh icle in the la ne.
Applies to: vehicles w ithout s ide ass ist : the ready
system does not warn you if you activate a turn
A ss ista nce sys te m s
signal before crossing the lane marker line. In
t h is case, it assumes that you are changing lanes
intentionally .
Applies to: vehicles wi th adap tive c ruise contro l:
there is no corrective steering or warnings if the
system recognizes a distinct passing maneuver .
If the condit ions are met, traffic jam ass ist
switches on at speeds under approximately
40 mph (65 km/h)
qpage 116.
A WARNING
=
- The system warns the driver that the vehicle
is leaving the lane using corrective steering.
The driver is always responsible fo r keeping
the vehicle within the lane.
- The system can help you keep the vehicle in
the lane, but it does not drive by itself. Al­
ways keep your hands on the stee ring
wheel.
- Cor rective stee ring may not occur in certain
situations, such as during heavy b raking.
- There may be cases whe re the camera does
not recognize all lane marker lines. Cor rec­
tive steering can only take place on the s ide
of the vehicle where lane marker lines are
detected.
- Other road structu res or objects could poss i­
b ly be identified unintentionally as lane
marker lines . As a result, corrective steering
may be unexpected or may not occur.
- The camera view can be restricted, for ex­
ample by vehicles driving ahead or by rain,
snow, heavy spray or light shining into the
camera. Th is can result in active lane ass ist
not detecting the lane marker lines or de­
tect ing them incorrectly .
- In certain s ituations where visibility is low,
the vehicle may switch from an "early" to
"late" steering correct ion.
- Under certain condit ions such as ruts in the
road, an inclined roadway or crosswinds, the
correct ive steer ing alo ne may not be enough
to keep the vehicle in the middle of the lane .
- For safety reasons, act ive lane assist must
not be used when there are poor road and/
or weather conditions such as slippery roads, fog, gravel, heavy rain, snow and the
125

Ass is tan ce sys tems
-If the lanes are narrow or if your are driving on
the edge of your lane. If this is the case, the system may have detected a vehicle in another
lane that is
not adjacent to your current lane.
-If you are driving through a curve . Side assist
may react to a vehicle that is in the same lane
or one lane over from the adjacent lane.
-If side assist reacts to other objects (such as
roadside structures like guard rails).
- In poor weather condit ions . The side assist
funct ions are limited.
Do not cover the radar
sensors ¢ fig. 130 with
stickers, deposits, bicycle wheels or other ob­
jects, because this will impair the function. Do
not use side assist when towing a trailer. For in­
formation on cleaning,
see¢ page 354 .
A WARNING
-Always pay attention to traffic and to the
area around your vehicle. Side assist cannot
replace a dr iver's attention . The driver alone
is a lways responsible for lane changes and
similar d riving maneuvers.
-In some situat ions, the system may not
function or its funct ion may be limited. For
example :
-If vehicles are approach ing or being left
behind very quickly. The display may not
turn on in t ime .
-In poor weather conditions such as heavy
rain, snow or heavy mist.
-On very wide lanes, in tight curves, or if
there is a rise in the road surface. Vehicles in the adjacent lane may not be detected because they are outs ide of the sensor
range .
(D Note
The sensors can be displaced by impacts or
damage to the bumper, whee l housing and
underbody. Th is can impa ir the system. Have
an authorized A udi dealer or authorized Audi
Serv ice Facility check their function .
