86 Audi adaptive cruise control and braking guard
When approaching a moving vehicle up ahead,
the adaptive cruise control system automati
cally brakes to match that object's speed and
then maintains the stored distance. If the ve
h icle ahead accelerates, adaptive cruise con
trol will also accelerate up to the stored
speed.
The higher the speed , the greater the distance
in yards (meters)
c::> & . The Distance 3 setting
is recommended .
The distances prov ided are spec ified values .
Depending on the driving situation and the
how the vehicle ahead is driving, the actual
d istance may be more or less than these tar
get distances.
The various symbols for the time increments
appear briefly in the information line @
c::> page 83, fig . 91 when you change the set
tings .

A WARNING ,. -
Following other vehicles too closely in
creases the risk of collisions and serious
personal inj ury.
- Setting short distances to the traffic
ahead reduces the time and distance
available to bring your vehicle to a safe
stop and makes it even more necessary
to pay close attention to traffic. -
Always obey applicable traffic laws, use
good judgment, and select a safe follow ing d istance for the traff ic, road and
weather conditions.
@ Tips
- Distance 3 is set automatically each time
you switch the ignition on.

Audi adaptive cruise control and braking guard 87
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 96 Instrument cluster: approach warning
Braking guard uses radar sensors and a video
camera . It also functions within the limits of
the system when adaptive cruise control is
switched off .
What can braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes sud
denly or if your own vehicle is t raveling at a
high speed and approaching a vehicle up
ahead that is moving more slowly . Braking
guard does not react if it cannot detect the
situation.
The system advises you of various situations:
- The
distance warning is given if you are too
close to the vehicle ahead for a long time. If
the vehicle ahead brakes sharply, you will not be able to avoid a collision . The indicator
light
I in the display comes on .
- The
approach warning is given when a de
tected vehicle up ahead in your lane is mov
i ng much more slowly than you are or if it
brakes sharply . When this warning is given,
it may only be possible to avoid a collision
by swerving or braking sharply. The indicator
l ight
I and indicator in the display will warn
you about the danger
c::> fig . 96. You will a lso
hear an acoustic signal.
11 This is not ava ilable in som e coun tri es.
If you do not react fast enough or do not react
at all to the situation, braking guard will inter
vene by braking.
- I f a collision is imminent, the system will
first provide an
acute warning by briefly and
sharply applying the brakes.
- If you do not react to the acute warning,
braking g uard can brake with increasing
force within the limits of the system . This
reduces the vehicle speed in the event of a
collision.
- The system can initiate maximum braking
shortly before a collision
1 ) . Full deceleration
at high speeds occurs only in vehicles with
adaptive cru ise control and side assist (pre
sense plus) .
- If the braking guard senses that you are not
braking hard enough when a collision is im
minent, it can increase the brak ing force .
- The pre sense functions also engage when a
collision is imm inent
c::> page 187 .
Which function s can be controlled?
You can switch braking guard and the dis
tance/approach warning on or off in the MMI
c::> page 88, Settings in the MMI.
A WARNING
Lack of attention can cause collisions, oth
er accidents and serious personal injuries .
The braking guard is an assist system and
cannot prevent a collision by itself. The
driver must always intervene. The driver is
always responsible for braking at the cor
rect time.
- Always pay close attent ion to traffic,
even when the braking guard is switched
on. Be ready to intervene and be ready to
take comp lete control whenever necessa
ry . Always keep the safe and legal dis
tance between your vehicle and vehicles up ahead .
- Braking guard works within limits and
will not respond outside the system lim its, for example when approaching a

88 Audi adaptive cruise control and braking guard
stopped vehicle or stationary obstacle (end of a traffic jam or vehicle that has
broken down in traffic).
- Always remember that the radar sensor
for the braking guard works only within
defined detection and range limits that
may prevent the proper detection of oth
er vehicles.
- The radar sensor's function and range
can be reduced by rain, snow and heavy
spray . Moving vehicles up ahead may not
be promptly detected or may not be de
tected at all.
- Reflective surfaces including crash barri
ers or tunnel entrances may impair the
function of the radar sensor.
({) Tips
-You can cancel the braking with increas
ing force that is initiated by the system
by braking yourself, by accelerating no
ticeably or by swerving.
- Braking guard error messages
¢page 88.
- Keep in mind that braking guard can
brake unexpectedly . Always secure any
cargo or objects that you are transport
ing to reduce the risk of damage or in
jury.

- If you restrict or switch off the ESC, the
braking guard also switches itself off
¢page 191.
- Switch braking guard off when you are
loading the vehicle onto a vehicle carrier,
train, ship or other type of transporta
tion. This can prevent undesired warn
ings from the braking guard system.

94 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 or
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 or 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. 104 with
stickers, deposits, bicycle wheels or other ob
jects, because this will affect the funct ion . For
information on cleaning, refer to
~ page 203.
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
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles un
der 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 approaching or being left
behind very quickly. The disp lay may
not turn on in time.
- in poor weather conditions such as
heavy rain, snow o r 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. .,..
