-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 on
coming objects.
- The function of the radar sensors can be
affected by reflective objects such as
guard rails, the entrance to a tunnel,
heavy rain or ice.
- Never follow a vehicle so closely that you
cannot stop your vehicle safely. The
adaptive cruise control cannot slow or
brake the vehicle safely when you follow
another vehicle too closely. Always re
member that the automatic braking
function cannot bring the vehicle to a
sudden or emergency stop under these
conditions.
- To prevent unintended operation, always
switch ACC off when it is not being used.
(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 result. Have an authorized Audi dealer
or authorized Audi Service Facility check
their function.
In curves
Applies to vehicles: with Audi adaptive cruise control and
Audi pre se nse front
Fig. 76 Example: driv ing into a curve
Audi adaptive crui se control 87
When driving into a curve q fig. 76 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 accelerator pedal briefly.
Stationary objects
Applies to vehicles: with Audi adaptive cruise control and
Aud i 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,
if a detected vehicle @turns or changes
lanes, the adaptive cruise control will not re
act to a stopped vehicle@. Press the brake
pedal to slow your vehicle down .
Pre sense front
Pre sense front only reacts to stationary ob
jects at low speeds.

What can adaptive cruise control do?

On ope n roads w ith no t raff ic, i t fun ctions like
a cruise co ntro l system . Th e stored s peed is
main taine d. When approach ing an object
ahead and the system detects it, the ada ptive
cr uise control system automatically brakes to
match that ob ject's speed and then maintains
the stored d istance. As soon as the system
does not detect an object ahead, adaptive
cru ise control accelerates up to the s to red
speed .
W ith in the lim its of the system, adaptive
cru ise contro l can brake in stop-and-go traff ic

and stay at a stop, within the limits of the sys
tem.

Criteria for switching off
The adaptive c ruise control switches off for
safety reasons when stationary:

- when the veh icle is stationary for more than
3 minutes,
- when the dr iver's safety be lt is not fastened .
,&. WARNING
If the message ACC autom . go1l appears,
the vehicle continues driving, even if there
is an obstacle between your vehicle and
the object ahead. This increases the risk of
an accident.
ll This is not available in some co un tri es .
(D Tips
If adaptive cruise contro l is active and your
vehicle does not start driving even though
the message ACC autom. go

you can start by tapp ing the accelerator
pedal.
- If an obstacle is detected when driving
w ith adaptive cru ise control, the system
w ill request you to begin driving

When approaching an object detected ahead ,
the adaptive cru ise cont ro l system brakes to

A WARNING
-
- Driving too close to other vehicles in
creases the risk of co llisions and ser ious
inju ries .
- Sett ing s hort dista nces to veh icles ahead
reduces the distance and time that you
have to stop your vehicle safe ly. This in
creases the need for yo u to pay attention

- Always follow applicable traff ic laws, use
common sense and select a distance to

Audi pre sense
Introduction
Applies to vehicles: with Audi pre sense basic or Audi pre
sense front
Within the limits of the system, pre sense ba
sic and pre sense front can initiate steps to
protect vehicle occupants in certain danger
ous situations.
Critical driving situations can be recognized by
the pre sense front v ia a network of differe nt
vehicle systems and can take steps to prepare
the vehicle occupants for a potentia l collision.
The pre sense front works with a radar sensor
and a video came ra* .
It also functions within
the limits of the system when adapt ive cruise
control * is switched off.
General information

A WARNING
Also follow the general information found
on
~ page 86, General information.
Audi pre sense basic
Descript ion
Applies to vehicles: with Audi pre sense basic
The function of the pre sense basic is activat
ed at a speed of 20 mph (30 km/h) or higher.
The following functions can be triggered un
der certain conditions within the limits of the
system:
- T ensioning of the safety be lts (for example,
during heavy braking) : The front safety belts
have reversib le be lt pretensioners. If a colli
sion does not occur, the safety belts loosen
s light ly and are ready to trigger again .
- Closing the windows and the sunroof* (for
example, when over- or understeering): The
windows and the sunroof" close until there is only a small gap open. Audi drive select:
The dep loyment time is
adapted in dynamic mode.
A WARNING
-The pre sense basic cannot overcome natu- ral phys ica l laws.
It is a system designed to
assist and it cannot prevent a coll is ion. Do
not let the increased safety provided
tempt you into taking risks. This could in
crease your r isk of a collis ion.
- The system can deploy incorrectly due to system-specific limits .
(D Tips
-Certa in pre sense bas ic functions switch
off when ESC is switched off (sport
mode) or when dr iving in reverse .
- The pre sense bas ic functions may not be
available if there is a ma lfunction in the
ESC system or the a irbag control mod
ule .
- Note that with pre sense bas ic, the rever
sible safety belt pretensioner on the
front passenger 's side deactivates when
the front passenger's a irbag is deactivat
ed.
Audi pre sense front
Description
Applies to vehicles: with Audi pre sense front or Audi
adapt ive cru ise control
Pre sense front informs yo u if the distance to
the vehicle ahead falls below the safe distance
for an extended period of time. It can warn of a possible collision and initiate braking ma
neuvers, within the limits of the system .
When detected in time, the system can assess
dangerous situat ions where an object ahead
brakes suddenly or if your own veh icle is trav
eling at a high speed and approaching an ob
ject that is moving more slow ly . If detection is
not possible, then p re sense fro nt does not re
act.
