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 regulating 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
c:::> page 98.
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.

The area that contains the radar sensor
c:::> fig. 103 must never be cove red by stickers
or other objects or obstructed with dirt, in­
sects, snow or i ce that will interfere with the
adaptive cruise control system and braking
guard. For information on cleaning, refer to
c:::> page 193. The same applies for any modifi­
cations made in the front area . T
he function of the adaptive cruise cont rol
system and braking guard is limited under
some condit ions:
- Objects can only be detected when they are
within sensor range
c:::>page 94, fig . 106.
-The system has a limited ability to detect
objects that are a short d istance 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

A WARNING
-
Always pay attention to traffic when adap-
tive cruise contro l is switched on and brak­
ing guard is active. As the driver, you are
still respons ible for starting 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
serio us personal injury.
- Never let the comfor t and convenience
that adaptive cruise control and braking
guard offer distract you from the need to
be alert to traffic conditions and the
need to remain in full control of your ve­
h icle at a ll times,
- Always remember that the adaptive
cru ise contro l and brak ing guard have
lim its -they will not s low 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
mov ing, such as vehicles stopped in a
traffic jam, a stalled or disabled vehicle.
If registered by the radar sensor, vehicles
or obsta cles that are not moving can
trigger a co llision warning and if

F ig . 11 3 Instrumen t cl uste r: approach warn ing
Braking guard uses a radar sensor. It also
functions within the limits of the system
when adaptive cruise cont ro l is switched off .
What can Audi braking guard do?
When detected i n time, the system ca n assess
situations when a vehicle ahead brakes sud­
denly or if your own veh icle is traveling at a
hi gh speed and approachi ng a ve hicle up
a head that is moving more slowly . Brak ing
guard does not react if i t can not detect the
situation.
The system advises you of various situations :
- The
distance warning is g iven if you are too
close to t he vehicle ahead for a long time . If
the vehicle ahead b rakes sharply, you w ill
not be ab le to avoid a c oll is io n. The indicator
li ght
I in the display comes on .
- The
approach warning is g iven when a de­
tected vehicle up ahead in yo ur lane is mov­
i ng much more slowly than you are or if it
brakes sha rply . W hen th is wa rning is given,

102 Audi side assist
Side assist functions at speeds above approxi­
mately 19 mph (30 km/h).
(D Vehicles that are approaching
I n certain cases, a vehicle will be classified as
cr itica l for a lane change even if it is still
somewhat far away . The faster a vehicle ap­
proaches, the sooner the display in the exteri ­
or mirror will turn on.
@ Vehicles traveling with you
Vehicles traveling with you are indicated in the
exterior m irror if they are classified as critica l
for a lane change. All vehicles detected by
side assist are indicated by the time they en­
ter your "blind spot", at the latest.
@ Vehicles left behind
If you slowly pass a vehicle that side assist has
detected (the difference in speed between the
vehicle and your vehicle is less than 9 mph
(15 km/h), the disp lay in the exterior mirror
turns on as soon as the vehicle enters your blind spot.
The display will not turn on if you quickly pass
a vehicle that side assist has detected (the dif­
ference in speed between the vehicle and your
vehicle is greater than 9 mph (15 km/h).
Functional limitations
The radar sensors are designed to detect the
left and right adjacent lanes when the road
lanes are the normal width. In certain situa­
tions, the display in the exterior mirror may
turn on even though there is no vehicle locat­
ed in the area that is critical for a lane change.
For example:
- if the lanes are narrow or if your are driving
on the edge of your lane. If this is the case,
the system may have detected the vehicle in
another lane that is
not adjacent to your
current lane.
- if you are driving through a curve. Side assist
may react to a veh icle that is one lane over
from the adjacent lane.
- if side assist reacts to other objects (such as
high or displaced guard ra ils). -
In poor weather conditions . The side assist
functions are limited.
Do not cover the rada r senso rs~
fig. 117 with
stickers, deposits, bicycle wheels or other ob­
jects, because this will affect the function . For
information on cleaning, refer to~
page 193.
A WARNING
-
-Always pay attention to traffic and to the
area around your vehicle. Side assist can­
not replace a driver's attention. The driv­
er alone is always responsible for lane
changes and similar dr iving maneuvers .
- Improper reliance on the side assist sys­
tem can cause coll is ions and serious per­
sonal injury:
- Never rely on ly on side assist when
changing lanes.
- Always check rear view mirrors to make
s ur e that it is safe to change lanes.
- Side assist cannot detect all vehicles un­
de r all conditions- danger of accident!
- Please note that side assist indicates
there are approaching vehicles, or
vehicles in your blind spot, only after
your vehicle has reached a driving speed
of at least 19 mph (30 km/h).
- In certain sit uations, the system may not
function or its function may be limited.
For example:
- if vehicles are approach ing or being left
behind very quickly. The disp lay may
not turn on in time.
- in poor weather conditions such as
heavy rain, snow or heavy mist.
- on very wide lanes, in tight curves or if
there is a rise in the road surface.
Vehicles in the adjacent lane may not
be detected because they are outside
of the sensor range .
([) Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
u nderbody. This can affect the system. .,..

Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers fo r the express purpose of capturing
data for retrieval after an accident or crash
event . EDR's are sometimes ca lled "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
A lthough your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, eng ine function, em is­
sion control, as well as for the airbags and
safety belts.
These electronic contro l modules also record
vehicle-re lated data during normal vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited pe riod of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only
be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of vehicle control. It works
only when the engine is running. ESC detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering assistance to help hold the
vehicle on the driver's intended course. The in­
dicator light
G) in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
physics. It wi ll not always be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of
dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it wou ld on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered.
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic and weather condit ions. ESC can­
not override the vehicle's physical limits, in­
crease the available traction, or keep a vehicle
on the road if road departure is a result of
drive r inattention. Instead, ESC improves the
poss ibility of keeping the vehicle under con­
trol and on the road during ex treme maneu­
vers by using the driver's steering inputs to
help keep the vehicle going in the intended di­
rection . If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
