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.
Changing the speed

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.
-

-Under some circumstances, traffic sign rec­
ognition may not detect traffic s igns cor­
rectly or detect them at all. As a result, the
system may not display the correct speed
limit or any speed limit.
- Traffic sign recognition does not adapt your
vehicle's speed to match the speed
limit!
-The display in the instrument cluster is
based on the units of measurement used for
speed in that country. As a result, the d is­
play
50 in the instrument cluster can mean
either km/h o r mph, depending on the coun ­
try .

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.

Audi adaptive cruise
control
Description
A ppl ie s to: ve hicles w ith Audi adaptive cruise co ntro l
Fig. 107 Detect ion range
The adaptive cruise control system is a combina­
tion of speed and distance regulation.
It assists
the dr iver by both regulating the speed and
maintaining a distance to the vehicle driving
ahead, within the limits of the system . If the sys­
tem detects a vehicle driving ahead, the adaptive
cru ise control can brake and acce lerate your vehi­
cle. This increases driving comfort dur ing long
tr ips on highways and in stop-and -go traff ic (au ­
tomatic transmission*).
What can adaptive cruise control do?
The adaptive cruise contro l system uses video, ra­
dar, ultrasound and navigation data. Veh icles
108
driving ahead can be recognized up to 650 feet
(200 m) away.
P red ictive functions offer the driver additional
comfort and contribute to the reduction in fue l
consumption and CO2 emiss ions
r:!> page 115.
On open roads with no traffic , it functions like a
c ruise control system. The stored speed is main­
tained . When approaching a vehicle driving
ahead, the adaptive cruise contro l system auto­
matically brakes to match that vehicle's speed
and then maintains the set distance . As soon as
the system does not detect a vehicle dr iving
ahead, adaptive cruise control accelerates up to
the stored speed.
App lies to: vehicles wit h auto matic transmissions
In stop-and-go traffic, adaptive cruise control can
brake until the veh icle is stationary and then can
also start driving again automat ically under cer­
ta in cond itions
r:!> page 112 .
In traffic jams or s top-and-go traffic, traffic jam
ass ist can ass ist the driver
r:!> page 116.
Which functions can be controlled?
When you switch adapt ive cru ise control on, you
can set the current speed as the "contro l speed"
r:!> page 110, Switching on/off.
When dr iving, you can stop cruise control
c:>page 113 or change the speed c::;,page 112 at
any time .
You can also set the distance to the vehicle driv­ i ng ahead and set the driving mode of the adap­
tive cru ise cont rol
c::;, page 113 .

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.

In curves
Applies to: vehicles w ith Audi adaptive cruise co ntro l
Fig. 109 Example: dr iv ing into a curve
When driving into a curve ¢ fig. 109 and out of a
curve, the adaptive cru ise control may react to a
veh icle in the neighboring lane and apply the
brakes. You can prevent that by pressing the ac­
celerator pedal briefly.
Stationary vehicle s
Applies to: ve hicles with Audi adaptive cruise co ntro l
F ig . 110 Example: veh icle c hanging lanes and stationa ry

Within the limits of the system, adaptive cruise
control can react to stationary vehicles
¢
fig. 110, as long as you are driving slower than
30 mph (SO km/h) and the system class ifies the
possible passing maneuver as low. For example,
if a vehicle that was already detected
@ turns or
changes lanes, the adaptive cruise contro l reacts
to the stat iona ry vehicle ahead of
it @ .

Veh icles with manual transmission
App lies to : vehicles wit h Audi adapt ive cruise control and
manual t ra n smi ssio n
The adaptive cru ise control is available from 1st
gear through 6th gear in the normal speed
range.
When the adaptive cruise contro l is turned on,
you must press the clutch to shift gears (as usu­
al). When sh ift ing normally or when pressing the
clutch, the adaptive cruise control remains
turned on.
After you have engaged the gear, you do
not
need to press the gas pedal. The adaptive cru ise
contro l accelerates automat ically if necessary .
