-Please note that unconsciously "resting"
your foot on the accelerator pedal prevents the cruise control from braking. This is due
to the control system be ing overr idden by
the driver 's acceleration .
-If there is a b rake system malfunction such
as overheating when the speed warning sys
tem is switched on, the braking function in
the system will be deactivated. The remain

Audi adaptive cruise control
Description
Applies to veh icles: w ith Audi adaptive cruise control
F ig. 80 Det ect ion rang e
The adaptive cruise control system is a combina
tion of speed and distance reg ulation . It assists
the driver by bot h reg ulating the speed and
maintaining a distance to the object ahead, w ith -
96
in the abilities o f the system. If the system de
tects an object, adaptive cruise control can brake
and acce lerate your veh icle . This makes driving
more comfortab le both on long stretches of
highway and in stop-and-go traffic.
What can adaptive crui se con trol do?
The adaptive cruise contro l system uses radar
and a video camera. The radar is subject to desig
nated system limits
q page 97.
On open roads with no traffic, it funct ions like a
cruise control system . The stored speed is main
tained. When approaching an object ahead and
the system detects it, the adapt ive cruise control
system automatically brakes to match that ob
ject's speed and then maintains the stored dis
tance. As soon as the system does not detect an object ahead, adapt ive cr uise control accelerates
up to the sto red speed .
Within the limits of the system, adaptive cruise
control can brake in stop -and -go traffic until the
vehicle is stat iona ry and then beg in driving again
under certain cond itions
q page 100, Driving in
stop-and-go traff ic.
Which functions can be controlled?
When you swi tch adapt ive cru ise control on, you
can set the current speed as the "control speed"
q page 98, Switching on/off .
When driving, yo u can stop cruise contro l
q page 100 or change the speed q page 100 at
any time .
You can also adjust the following sett ings:

General information
Applies to vehicles: with Audi adaptive cruise control and Audi
pre sense front
Fig. 81 Front of vehicle: sensor
The general information applies to adaptive
cruise control* and pre sense front*
r::!>page 103.
The radar sensor area r::!> fig. Bl must not be cov
ered with stickers, deposits or any other obstruc
tions as it may impair the function of the adap
tive cruise control and the pre sense front. For in
formation on cleaning, refer tor::!>
page 235. The
same applies for any modifications made in the
front area .
The function of the adaptive cruise control sys tem and pre sense front is limited in some condi
tions :
- Objects can only be detected when they are
within the sensor ranger::!>
page 96, fig. 80.
-The system has a limited ability to detect ob
jects 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 clearance
or an overhanging load are detected late or not
detected at all.
- When driving through curves
r=> page 98.
-With stationary objects r::!> page 98.
A WARNING
Always pay attention to traffic when adaptive
cruise control is switched on and the pre
sense front is active
r::!> page 103. As the d riv
er, you are still responsible for starting and
for maintaining speed and distance to other objects. The pre sense front is used to assist
you. The driver must always take action to
Assist
avoid a collision. The driver is always responsi
ble for braking at the correct time.
- Using adaptive cruise control incorrectly can
cause collisions, other accidents and serious
injuries.
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydroplan
ing). Using the system under these condi
tions could result in a collision.
- Switch adaptive cruise control off tempora
rily when driving in turning lanes, on ex
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the set speed when in these situations.
- 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 objects such
as stopped traffic, adaptive cruise control
will not respond and pre sense front will
have limited function.
- The adaptive cruise control system and pre
sense front do not react to people, animals,
objects crossing the road or oncoming ob
jects.
- 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.
- Always maintain enough distance from
vehicles ahead so that you can still brake
your vehicle safely. The adaptive cruise con trol cannot safely slow your vehicle or brake it to a stop if you are driving too close be
hind a vehicle. Please note that the auto
matic braking function cannot brake sud
denly or apply the brakes fully under these
conditions.
- To reduce the risk of unintended actions,
switch the ACC off when you are not actively
using it.

Assist
(D Note
The sensor can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. The adaptive cruise control and
pre sense front may become impaired as a re
sult. Have an authorized Audi dealer or au
thorized Audi Service Facility check their func
tion.
In curves
Applies to vehicles: with Audi adaptive cruise control and Aud i
pre sense front
Fig. 82 Example: driving into a curve
When driving into a curve~ fig. 82 and out of a
curve, the adaptive cruise control may react to an
object in the neighboring lane and apply the
brakes. You can prevent that by pressing the ac
celerator pedal briefly .
Stationary objects

pre sense front

Adaptive cruise control
The adaptive cruise control system only reacts to
objects that are moving or that the system has
already detected as moving. For example, it can
react when a vehicle that has already been de
tected @turns or changes lanes, but adapt ive
cruise control does not react to a stationary vehi
cle @. Press the brake pedal to slow your vehicle
down!
Pre sense front
Pre sense front only reacts to stationary objects
at low speeds.

The distance between the two vehicles will
change in the instrument cluster display .
When approaching an object detected ahead, the adaptive cruise contro l system brakes to match
that object's speed and then regu lates to the
stored distance. If the object detected ahead ac
celerates, adaptive cruise control will also accel
erate up to the stored speed .
The higher the speed, the greater the distance in meters
