-Please note that unconsciously "resting"
your foot on the accelerator pedal prevents the cruise control from braking. This is be­
cause pressing the accelerator pedal over­
rides the cruise control system .
-If there is a brake 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
ing speed warning system functions will re­
ma in active, as long as the~ (USA mod­
els) /
fil (Canada models) indicator light is
on.
{i) Tips
- The cruise control system is ideal for
stretches w ith speed limits. The d river is re­
sponsible for adhering to the correct speed.
- The cruise control remains active when
shifting gears.
- The brake lights turn on when the brakes
are act ivated.

Audi adaptive cruise control
Description
Applies to vehicles: w ith Audi adaptive cruise control
Fig. 115 Detect ion range
The adaptive cruise control system is a combina­
tion of speed and distance regulation .
It assists
the driver by both regulating the speed and
maintaining a distance to the object ahead, with-
132
in the abilities of the system. If the system de­
tects an object, adaptive cruise contro l can brake
and acce lerate your vehicle. This makes driving
more comfortable both on long stretches of
highway and in stop-and-go traffic.
What can adaptive cruise control do?
The adaptive cruise control system uses radar
and a video camera. The radar is subject to desig­
nated system limits
i=> page 133 .
On open roads with no traffic , it functions like a
cruise contro l system. The stored speed is main ­
tained. When approaching an object ahead and
the system detects it, the adapt ive cr uise 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 acce lerates
up to the stored speed.
Within the limits of the system, adaptive cruise control can brake in stop -and -go traffic until the
vehicle is stat ionary and then begin driving agai n
under certain cond itions
i=> page 136, Driving in
stop-and-go traffic.
Which functions can be controlled?
When you switch adapt ive cru ise control on, you
can set the current speed as the "control speed"
i=> page 134, Switching on/off.
When dr iving, you can stop cruise control
i=> page 136 or change the speed c> page 136 at
any time .

p re se nse front
Fig. 116 Front o f ve hicle: sensor
The general information applies to adaptive
cruise control* and pre sense front*¢
page 139.
The radar sensor area¢ fig. 116 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 to
c:> page 2 74. 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 range
¢ page 132, fig. 115.
- 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
c:> page 134.
-With stationary objects c!;> page 134.
A WARNING
Always pay attention to traffic when adaptive
cruise control is switched on and the pre
sense front is active
c:> page 139 . As the driv­
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 a re not actively
using it.

A WARNING
- Using adaptive cruise control incorrectly can
cause collisions, other accidents and ser ious

- If you switch the ignit ion or the adaptive

A WARNING
If the message ACC autom. go1> appears, the
vehicle continues driving , even if there is an
obstacle between your vehicle and the ob je ct
ahead . This increases the risk of an accident .
@ Tips
If adaptive cruise control is act ive and your

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.

Audi pre sense basic
Description
Applies to vehicles: with Audi pre sense basic
The function of the pre sense basic is activated at
a speed of 20 mph (30 km/h) or h igher .
The following functions can be triggered under certain condit ions w ith in the lim its of the sys­
tem:
- Tensioning of the safety belts (for examp le,
during heavy braking): the front safety belts have reversib le be lt tens ioners. If a collision
does not occur, the safety belts loosen slightly
and are ready to tr igger aga in.
- Closing the windows and the sunroof* (for ex­
ample when over- or understeering): the win­
dows close until the re is only a small gap open
and the s unroof* closes all the way .

_&. WARNING ~
The pre sense basic cannot overcome natural

Audi pre sense front
Description
A pp lies to veh icles: with Audi pre sense front or Audi adapt ive

Pre sense front informs you if the distance to the
vehicle ahead falls below the safe distance for an
extended period of time.
It c an warn of a poss i­
b le co llision and initiate braki ng maneuve rs,
within the limits of the system.
When detected in time, the system can assess
dangerous s ituations where an object ahead
b rakes suddenly or if your own vehi cle is t raveling
at a high speed and approaching an object that is
mov ing more slowly. If detect ion is not possible,
then pre sense front does not react.
