Audi adaptive cruise control and braking guard

Description
Applies to: vehicles with Audi adaptive cruise contro l
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 suddenly
or if your own veh icle is traveling at a high speed
and approaching a vehicle up ahead that is mov
ing more slowly. Braking guard does not react if
it cannot detect the si tuat ion.
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 . T he indicator light .
in the d isplay comes on .
- The
approach warning is given when a detected
vehicle up ahead in your lane is moving much
more slowly than you are or if it brakes sharply.
When this warning is g iven, it may only be pos
s ib le to avoid a collision by swerving or braking
sharp ly. The indicator light. and indicator in
the display will warn yo u about the danger
¢
fig. 96. You will also hear an acoustic signa l.
If you do not react fast enough or do not react at
all to the situation, braking guard will intervene
by braking.
N "' ll This is not available in some countries . ......
-If a collision is imminent, the system wi ll first
provide an
acute warning by briefly and sharply
apply ing the brakes .
- If you do not react to the acute warning, brak
ing guard can brake with increas ing force with
in the limits of the system. This reduces the ve
hicle speed in the event of a collision.
- The system can initiate maximum braking
shortly before a collision
1 ). Full dece leration at
high speeds occurs only in vehicles with adap
tive cruise control and side assist (pre sense plus).
- If the braking guard senses that you are not
braking hard enough when a collision is immi
nent, it can increase the braking force.
- The pre sense functions also engage when a
collision is imm inent ¢
page 177.
Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the MMI
¢ page 86, Settings in the Infotainment sys
tem .
A WARNING
--
Lack of attention can cause collisions, other
accidents and serious personal injuries. The
braking guard is an assist system and cannot
prevent a collision by itself . Th e driver must
always intervene. The driver is always respon
sib le for b raking at the co rrect time.
- Always pay close attention to traffic, even
when the braking guard is switched on. Be
ready to intervene and be ready to take
complete control whenever necessary. Al
ways keep the safe and legal distance be
tween your vehicle and vehicles up ahead.
- Brak ing guard works with in limits and will
not respond outside the system limits, for
example when approach ing a stopped vehi
cle or stationary obstacle (end of a traffic
jam or vehicle that has broken down in traf
f ic).
- Always remember that the radar sensor for
the braking guard works only within defined
~

Audi adaptive cruise control and braking guard
detection and range limits that may prevent
the proper detection of other 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 detected
at all.
- Reflective surfaces including crash barriers
or tunnel entrances may impair the function
of the radar sensor.
@ Tips
- You can cancel the braking with increasing
force that is initiated by the system by brak
ing yourself, by accelerating noticeably or
by swerving .
- Braking guard error messages¢
page 86.
- Keep in mind that braking guard can brake
unexpectedly. Always secure any cargo or
objects that you are transporting to reduce
the risk of damage or injury.

Side assist functions at speeds above approxi

19 mph (30 km/h).
(D Vehicles that are approaching
In certain cases, a vehicle will be classified as
cr itical for a lane change even if it is still some
what far away. The faster a veh icle approaches ,
the sooner the display in the exterior mirror w il l
turn on.
@Vehicles traveling with you
Vehicles traveling with you are indicated in the
exterior mirror if they are classified as critical for
a lane change. All vehicles detected by side assist
92
are indicated by the time they enter your "blind
spot", at the latest .
@ Vehicles left behind
If you slow ly pass a vehicle that side assist has
de tected (the diffe rence in speed between the
vehicle and your vehicle is less than 9 mph or 15
km/h), the display 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 ass ist has detected (the differ
ence in speed between the vehicle and your vehi
cle 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 certa in situations, the dis
play in the exterior mirror may turn on even
thou gh there is no vehicle located in the area
that is crit ica l for a lane change. For example:
- if the lanes a re 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 anoth
er lane that is
not adjacent to your current lane.
- if yo u are driving through a curve. Side assist
may react to a vehicle that is one lane over
from the adjacent lane.
- if side assist reacts to other objects (such as
high or displaced guard rai ls).
- In poor weather conditions. The side assist
functions are limited.
Do not cover the radar sensors <=?
fig. 104 with
stickers, deposits, bicycle wheels or other ob
jects, because this wi ll affect the function. For in
format ion on cleaning, refer to <=?
page 193.
_& WARNING
-Always pay attention to traffic and to the
area around your vehicle. Side assist cannot
replace a driver's attention . The driver alone
is always responsible for lane changes a nd
similar driving maneuvers .
- Improper reliance on the side ass ist system
can cause collis ions and serious pe rsonal in-
-
Jury: .,,.

-Never rely only on side assist when chang
ing lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles under
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 situations, the system may not function or its function may be limited. For
example:
- if vehicles are approaching or being left
behind very quickly. The display may not
turn on in time.
- in poor weather conditions such as heavy
rain, snow or heavy mist.
- on very w ide 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.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can affect the system. Have
your authorized Audi dealer or authorized
Audi Serv ice Facility check their function .
(!j) Tips
-If the window g lass in the driver's doo r or
front passenger's door has been t inted, the
display in the exterior mirror may be misin
