General information
The predictive eff ici ency assist helps the driver to
d rive with an ticipation and therefore helps to
save fue l. The sy stem a ccesses p redic tive trip da­

of cur ves) from the n avigat ion sys tem* . Informa ­
tion from the camera-based traff ic sign recogn i­
tion* is also app lied to recognize traffic signs
c:> page24.
The mess ages disp layed depend on the navi ga­
tion data * being up-to-date and the co rrect iden ­
tification by the traffic sign recognition *.
When adaptive cruise contro l* is sw itche d off,
the predi ctive efficiency ass ist only p rovides not i­

Audi adaptive cruise
control
Description
App lies to : vehicles wi th Audi adap tive c ru ise con trol
Fi g. 89 Detect io n range
The adaptive cru ise cont rol system is a comb ina­
tion of speed and dis tance regu lation.
It ass ists
t h e d river by bo th regu lating the speed and
maintain ing a d is ta nce to the vehicle driv ing
ahead, within the limits of the system. If the sys ­
tem detects a vehicle d riving ahead, the adaptive
cruise contro l can brake and accelerate yo ur vehi­
cle. T his makes driving more comfo rtable both
o n long st retches of hig hway and in stop-and-go
traffic .
What can adaptive cruise control do?
The adaptive cru ise control system uses video, ra­
dar, ultrasound and navigat ion data . Vehicles
driv ing ahead can be recognized up to 650 feet
(200 m) away .
Pred ictive functions offer the drive r additional
comfort and contr ibute to the reduct ion in fuel
consumption a nd CO2 em issions
r::::> page 102.
On open roads with no traffic, it functions like a
cruise contro l system. The stored speed is main ­
ta ined . When approaching a vehicle d riving
ahead, the adaptive cruise contro l system auto­
matically brakes to match that vehicle's speed
and then maintains the set dis tance. As soon as
the system do es not detect a vehicle dr iv ing
ahea d, adaptive cruise cont rol accelerates up to
t h e s to red spee d.
In stop-a nd-go traffic, adap tive cruise control can
brake until the veh icle is sta tionary a nd then can .,.

also start driving again automatically under cer­
tain conditions
c!;> page 100.
In traffic jams or slow-moving traffic, congestion
assist can assist the driver¢
page 104 .
Which functions can be controlled?
When you switch adaptive cruise control on, you
can set the current speed as the "control speed "
c!;> page 98, Switching on/off.
When driving, you can stop cruise control
c!;> page 100 or change the speed ¢ page 99 at
any time .
You can also set the dist ance to the vehicle d riv­
ing ahead and set the driving mode of the adap ­
tive cruise control¢
page 101 .
General information
Appl ies to: ve hicles with Audi adaptive cruise co ntro l
Fig. 90 Fro nt o f th e ve hicle : sensor s and video c amer a
The areas wi th the radar and ul trasonic senso rs
and the video camera¢
fig. 90 must not be cov­
ered by stickers, deposits or any other objects ,
because this can interfere with the adaptive
cruise control function. For information on clean­ ing, refer to¢
page 337. The same applies for
any modifications made in the front area .
In some driving situations , the adaptive cruise
control function is restricted:
- Vehicle s can only be detected when they are
within the sensor detection zones
¢ page 96,
fig . 89 .
-The system has a limited ability to detect
vehicles that are a short distance ahead, off to
the side of your vehicle or moving into your lane .
Assist
-Objects that are difficult to detect such as mo­
torcycles, v ehicles with high ground clearance
or an overhanging load are detected late or not
detected at all.
- When driving through curv es
c!;> pag e 98.
- When the vehicle is stationary ¢ page 98.
A WARNING
Always pay attention to the traffic around you
when adaptive cruise control is switched on .
As the driver, you are still responsible for your
own speed and the distance to other vehicles.
The adaptive cruise control is used to assist
you . The driver must always take action to
avoid a collision . The driver is always responsi­
ble for braking at the correct time .
- For safety reasons, do not use adaptive
cruise 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 risk of an ac­ cident.
- Switch adaptive cruise control off tempora­ rily when driving in turning lanes, on ex­
pressway exits (except if predictive control
is switched on) or in construction zones.
This prevents the vehicle from accelerating
to the stored speed when in these situa ­
tions .
- The adaptive cruise control 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 cruise control does not respond to
people, animals, or crossing or oncoming
objects.
- The function of the radar sensors can be af­
fected by reflective objects such as guard
rails, the entrance to a tunnel, heavy rain or
ice.

Assist
(D Note
The sensors can be displaced by impacts or
damage to the bumper , whee l housing and
underbody. This can impair the adaptive
cruise control. Have an authorized Audi dea ler
or authorized Audi Service Fac ility check their
function .
In curves
Applies to: vehicles with Audi adaptive cruise control
Fig . 9 1 Exa mple: drivin g in to a curve
When driving into a curve<=> fig. 91 and ou t of a
curve, the adaptive cruise 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 b rief ly.
Stationary vehicles
Applies to : vehicles with Aud i adaptive cruise contro l
Fig. 92 Example: vehicl e chang ing lane s and sta tiona ry ve ­
hi cle
Adaptive cruise control can react to a limited ex­
tent to stationary vehicles
c:> fig . 92, as long as
you are driving slow er than SO km/h and the sys­
tem classifies as possible passing maneuver as
low . For example, if a vehicle that was already
detected @turns or changes lanes, the adaptive
98
cruise contro l reacts to the stationary vehicle
ahead of it@ .
Switching on/off
Applies to: vehicles with Audi adaptive cruise control

If Dr ive r assis t is not shown in the instrument
cluster display, you can open it using the multi­
function steering wheel buttons
¢ page 12.
Based on the graphic display, you can determine
if the system is maintaining a distance to the ve­
h icle dr iving ahead and what that distance is .
No vehicle -no vehicle was detected driving
ahead .
Silver vehicle -a vehicle was detected driv ing
ahead.

A WARNING
If you press the !SET ! button when driv ing at
speeds below 20 mph (30 km/h), the veh icle
accelerates automatically up to 20 mph (30
km/h), wh ich is the minim um speed that can
be set.
@ Tips
- If you switch the ignition or the adaptive
cruise cont rol sys tem off, the set speed is
erased for safety reasons.
- The e lectronic stabilization control (ESC)
and the an ti-slip-regula tion (ASR) are auto­
matically switched on when the adap tive
cruise cont rol is swit ched on.
