Audi adaptive cruise control and braking guard 93
Audi adaptive cruise
control and braking
guard
Introduction
App lies to vehicles: with Audi adaptive cruise co ntrol
The adaptive cruise control system assists the
driver by regu lating vehicle speed and helping
to maintain a set distance to the vehicle
ahead, within the limits of the system . If the
system detects a moving vehicle up ahead,
adaptive cruise control can brake and then ac­
celerate your vehicle . This he lps to make driv­
ing more comfortable on long highway
stretches.
The braking guard system can warn you about
an impending collision and initiate braking
maneuvers ¢
page 99.
Adaptive cruise control and braking guard
have technical limitations that you must
know, so please read this section carefully, un­
derstand how the system works and use them properly at all times.
General information
General information
Applies to vehicles: with Audi adaptive cruise control
Fig. 103 Front of the vehicle: Position of radar sensor
The area that contains the radar sensor
¢
fig. 103 must never be covered by stickers
or other objects or obstructed with dirt, in­
sects, snow or ice that will interfere with the
adaptive cruise control system and braking
guard. For information on cleaning, refer to
¢
page 195. The same applies for any modifi­
cations made in the front area . The
function of the adaptive cruise control
system and braking guard is limited under
some cond itions:
- Objects can only be detected when they are
within sensor range
.:!>page 95, fig. 106.
-The system has a limited ability to detect
objects that are a short distance ahead, off
to the side of your vehicle or moving into
your lane.
- Some kinds of vehicles are hard to detect;
for examp le motorcycles, vehicles with high
ground clearance or overhanging loads may
be detected when it is too late or they may
not be detected at all.
- When driving through curves¢
page 94.
-Stationary objects¢ page 94.
A WARNING
-Always pay attention to traffic when adap-
tive cruise control is switched on and brak­ ing guard is active. As the dr iver, you are
still respons ible for start ing and for main­
tain ing speed and distance to other ob­
jects. Braking guard is used to assist you .
The driver must always take action to avoid
a col lision. The driver is always responsible
for braking at the correct time.
- Im proper use of adaptive cruise con trol
can cause collisions, other accidents and
serious personal inj ury .
- Never let the comfort and convenience
that adaptive cruise control and braking
guard offer distract you from the need to
be alert to traffic conditio ns and the
need to remain in full control of your ve­
hicle at all times,
- Always remember that the adaptive
cru ise control and brak ing guard have
limits -they will not slow the vehicle
down or maintain the set distance when
you drive towards an obstacle or some­
thing on or near the road that is not
moving, such as vehicles stopped in a
traffic jam, a stalled or disabled vehicle.
If registered by the radar sensor, vehicles
or obstacles that are not moving can
trigger a collision warning and if .,.

94 Audi adaptive cruise control and braking guard
confirmed by the video camera, an acute
collision warning.
- 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
hydroplaning). Using the system under
these conditions could result in a colli­
sion.
- Switch adaptive cruise control off tempo­
rarily when driving in turning lanes, on
expressway exits or in construction
zones. This prevents the vehicle from ac­
celerating 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 accelerator pedal. Doing so can over­
ride the speed and distance regulation.
- When approaching stationary objects
such as stopped traffic, adaptive cruise
control will not respond and braking
guard will have limited function.
- The adaptive cruise control system and
braking guard do not react to people, an­
imals, objects crossing the road or on­
coming objects .
- The function of the radar sensor 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.
{[) Note
The sensor can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. That could affect the adaptive cruise control system and braking guard.
Have your authorized Audi dealer or au­
thorized Audi Service Facility check their
function.
, In curves
Applies to vehicles: wit h Aud i adapt ive cr uise contro l
Fig. 104 Example: driv ing into a curve
When driving into a curve <=> fig. 104 and out
of a curve, the adaptive cruise control may re­ act to a vehicle in the next lane and apply the
brakes. You can override or prevent the brak­
ing by pressing the accelerator pedal briefly.
Stationary objects
Applies to vehicles: with Aud i adaptive crui se contro l
Fig. 105 Example: object changing lanes a nd station ­
a ry object
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 vehicle @, which has already been detect­
ed by the adaptive cruise control, turns or
changes lanes and another stationary vehicle
@ is located in front of that vehicle, the sys­
tem will not react to the stationary vehicle.
