operation. You are always responsible for
your speed and the distance between your
vehicle and other vehicles.
- For safety reasons, cruise control should not be used in the city, in stop-and-go traffic, on
winding roads and when road conditions are poor (such as ice, fog, gravel, heavy rain and
hydroplaning), because th is increases the
risk of an accident.
- Switch the cruise control off temporar ily
when driving in turn ing lanes, h ighway exits
o r in construction zones.
- Please note that unconsciously "resting"
your foot on the accelerator pedal prevents the cruise control from b raking. This is be­
ca use p ressing the acce le ra to r peda l ove r­
rides the cruise contro l system.
- If a brake system ma lf u nction such as over­
heating occurs when the c ruise contro l sys­
tem is switched on, the braking function in
the system may be switched off . The rest of
the cruise control system functions remain
act ive as long as the
@;\l)M~ (USA models) /
Bl (Canada models) indicator light is on.
Before driving downhill a long distance on a
steep hill, decrease your speed and select a
lower gear. Th is makes use of the eng ine
braking effect and relieves the brakes.
(D} Tips
-Applies to: vehicles with manual transmis­ sion: The set speed can on ly be reached if
the engaged gear permits it so that the en­
gine is not over-rewed and will run smooth­ ly. Therefore, s hift into the higher or lower
gear in a timely manner .
- The brake lights turn on when the brakes are applied automatically.

Traffic sign recognition assists you when driving
by displaying detected speed limits or signs pro­
hibiting passing in the instrument cluster display
¢ fig. 104. Within the limits of the system, the
legal speed limits in schoo l zones are detected
and displayed .
General information
Traffic sign recognition can detect standard
speed limit signs that are within the camera's vis­
u al field. With assistance from navigation data,
detected speed limits are evaluated and shown in
the d isplay. The traffic s ign for the current de­
tected speed lim it will blink in the display if you
exceed the warning threshold set in the Infota in­
ment system
¢ page 1 OS.
Th e traffic sign recognition is subject to certa in
system limitat ions and may be unava ilable or on­
l y part ially ava ilab le in the follow ing s ituations:
- when visibility is poor, such as in snow, rain,
fog or heavy spray
- when there is glare, for example from oncom­
ing traffic or the sun
- at high speeds
- if the camera's visual
field¢ fig. 105 is covered,
for examp le by dirt or stickers. For information
on cleaning,
see¢ page 354
- if the traffic signs are completely or partially
covered, for examp le by trees, snow, dirt or
other vehicles
- if speed traffic signs do not conform to the
standards
- if traffic signs are damaged or bent
- if traffic signs are displayed on sign holders
with electronic signs
- if the traffic signs o r the config uration of the
road have changed (navigation data is no lon­
ger up-to-date)
_& WARNING
Pay attention to traffic and the area around
your vehicle when traff ic sign recogn ition is
turned on . The traffic s igns installed on the
road always take precedence over the display .
The drive r is always responsible for assessing
the traffic situation.

Predictive efficiency
assist
Descript ion
Applies to: vehicles with predictive efficiency assist
General information
The pred ictive eff ic iency assist helps the driver to
d rive w ith anticipation and therefore helps to
save fuel. The system accesses predictive trip da­
ta (including speed limits, inclines and the radius
of curves) from the navigation system*. Informa­
tion from the camera-based traff ic sign recogni­
tion* is also applied to recognize traffic signs
r;;:;ipage 104.
The messages displayed depend on the naviga­
tion data* being up-to-date and the correct iden­
tification by the traffic sign recognition*.
When adaptive cruise contro l* is switched off,
the predictive efficiency assist only provides noti­
fications without controlled interventions. When
adaptive cruise control* is switched on, the sys­
tem responds to upcoming situations automati­
cally.
Vehicles with adaptive cruise control*
Refer to predictive control c> page 115.
Indicator in the instrument cluster display
Predictive messages appea r in the instr ument
cluster display to show the driver the appropriate
time to coast when a situation ahead requires
you to drive at a lower speed.
The messages are only shown if the cr uise control
system* or adaptive cruise control* is switched
off .
Assistance systems
An additional indicator appears in the head-up
display* .
Symbol Meaning
Remove your foot from the acceler -
"
ator pedal to slow down, because
there is a situation ahead that re- quires a lower speed.
If you see Driver assistance in the instrument
cluster disp lay, the following symbols will indi­
cate which situation the system is currently re­
acting to.

.&, WARNING ~ -
Pay attention to traffic and the area around
your vehicle when the efficiency assist is
switched on. The driver is always respons ible
for assessing the traffic situation.
(D Tips
- The wording of the message may vary de­
pending on the driving mode set in drive se­
lect* c> page 133 and the current selector
lever position (automatic transmiss ion*).
No messages are displayed when in the S
selector lever position or in
Dynamic mode.
- When a route is planned using the naviga­
tion system*, then the message feed is based on this route. Without route guid­
ance, the system uses an assumed route fo r
the message feed.
- There will not be a message for every s itua­
tion ahead, for example if there is not
enough distance remaining to react to the
situation.

General information
Appl ies to: ve hicles with Audi adaptive cruise contro l
Fig. 108 Fro nt of the vehicle: sensors and video camera
The areas with the radar and ultrasonic sensors
and the video camera
c:> fig . 108 must not be cov ­
ered by stickers, deposits or any other objects, because this can inte rfere with the adaptive
cr uise control funct ion. For information on clean­
ing, see
c:> page 354 . The same app lies for any
modifications made in the front area.
In some d riving situations, the adaptive cru ise
control funct ion is restr icted:
- Vehicles can only be detected when they are within the sensor detection zones
c:> page 108,
fig. 107.
- The system has a limited abil ity 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 clearan ce
or an overhanging load are detected late or not dete cted at all.
- When driving through curves
c:> page 110 .
-When the vehicle is stat ionary c:> page 110.
..&, WARNING
Always pay attent ion to the traffic aro und you
when adap tive cruise contro l is swi tched o n.
As the driver, you are s till responsible for your
own speed and the distance to other vehicles .
The adaptive cruise control is used to assist
you. The driver must a lways take action to
avoid a collision. The driver is a lways responsi­
ble for brak ing at the correct time.
A ss is ta nce syst ems
-For safety reasons, do not use adaptive
cru ise control when the road surface is in
poor condition and/or in bad weather condi­
tions (such as ice, fog, gravel, heavy rain and
hydroplaning). Using the system under
these conditions increases the r isk of an ac­
cident.
- Sw itch adaptive cruise control off tempora­
rily when dr iv ing in turning lanes, on ex­
p ressway ex its (except if predictive con trol
is switched on) or in const ruct ion zones.
This prevents the vehicle from acce lerating
to the stored speed when in these situa­
tions.
- The adaptive cruise contro l system will not
brake by itself if you put your foot on the ac­
celerator pedal. Doing so can override the
speed and distance regulation.
- When approaching stationary obstacles
such as stopped traffic, adaptive cruise con­
trol will respond with limited function.
- Adaptive cr uise control does not respond to
peop le, animals, or crossing or oncoming
objects.
- The funct ion of the radar sensors can be af­
fected by reflective objects such as guard rails, the entrance to a tunnel, heavy rain or
ice.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and underbody. This can impair the adaptive
cruise control. Have an authorized Audi dealer
or authorized Audi Service Facility check
the ir
f u nct ion.

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.

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.
