Audi braking guard
Description
Ap plies to vehicles: with Audi adaptive cruise co ntrol
Fig. 106 Instrume nt cluste r: approac h warn ing
Braking guard uses radar sensors and a video
camera. It also functions within the limits of
the system when adapt ive 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 traveling at a
h igh speed and approaching a vehicle up
ahead that is moving more slowly . Brak ing
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 collis ion. The indicator
light. 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 wa rning is given,
it may only be possible to avoid a collision
by swerving or braking sharply. Th e indicator
li ght . and indicator in the display will
warn you about the danger~
fig. 106. You
will also hear an acoustic signa l.
ll This is not av ailable in some coun tri es.
If you do not react fast enough or do not react
at all to the situation, braking guard wi ll inter·
vene by braking and the message
braking
guard intervention
will appear.
- If a collision is imminent, the system wi ll
first provide an
acute warning by briefly and
sharply applying the brakes .
- If you do not react to the acute warning,
braking guard can brake wit h increas ing
force w ithin the limits of the system . This
reduces the vehicle speed in the event of a
collision.
- The system can initiate max imum brak ing
shortly before a collision
1> . Full deceleration
at high speeds occurs only in vehicles with
adapt ive cr uise control and side assist (p re
sense plus) .
- If the brak ing 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
col lision is imminent ~
page 194.
Which functions can be controlled?
You can switch braking guard and the dis
tance/approach warn ing on or off in the MMI
~ page 99, 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
ca nnot prevent a collision by itself. The
driver must always intervene. The driver is
a lways respons ible for braking at the cor
rect time.
- Always pay close attention 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 veh icles
up ahead .
- Braking guard works within limits and
will not respond outside the system

(end of a traffic jam or veh icle that has
br oken down in traffic).
- Always remember that the radar sensor
for the braking guard works only withi n
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 al l.
- Reflective surfaces in cl ud ing crash barr i
ers or t unnel entrances may impair the
f unction of the radar sensor .
@ Tips
-You can cance l the braking w ith increas

by braking yo urself, by accelerating no
ticeab ly or by swerving .

snow, dirt, water or backlight ing).
- The vehicle 's speed is below the speed need

Side assist functions at speeds above approx i
mately 19 mph (30 km/h).
@ Vehicl es th at ar e approaching
In certain cases, a vehicle will be classified as
cr itical for a lane change even if it is still
somewhat far away. The fas ter a vehicle ap
p roaches, the sooner the display in the exteri
or m irror will t urn on.
@ V ehicles traveling with you
Vehicles traveling w ith you are indicated in the
exterior m irror if they are classified as cr itical
for a lane change. All vehicles detec ted by
side assist are indicated by the time they en
ter your "blind spot", at the latest.
Audi side assist 105
© Veh icle s left behind
If you s low ly pass a vehi cle that s ide assist has
detected (the difference in speed between the
vehicle and you r 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 disp lay will not t urn on if you quickly pass
a vehicle that side assist has detected (the dif
ference in speed between the veh icle and your
vehicle is greater than 9 mph or 15 km/h).
Functi onal 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 d isp lay in the exterior mirror may
turn on even though there is no veh icle locat
ed in the area that is cr itical for a lane change.
For example:
- if the lanes are narrow or if your are dr iving
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 a re driving through a curve. Side assist
may react to a vehicle that is one lane ove r
from the adjacent lane.
- if side assist reacts to other objects (such as
high or d isp laced guard rails) .
- In poor weather conditions. The side assist
functions are l imited .
Do not cover the radar sensors
c> fig. 114 with
stickers, depos its, bicycle wheels or other ob
jects, because this will affect the funct ion. Do
not use s ide ass ist when towing a trailer. For
i nformation on cleaning, refer to
c> page 214.
_&. WARNING
- Always pay attention to traffic and to t he
area a round your ve hicl e. S ide assist can
not replace a driver's attention. T he driv
er a lone is always responsible for lane
changes and similar driving mane uvers.
106 Audi side assist
-Improper reliance on the side assist sys
tem can cause collisions and serious
personal injury:
- Never rely only 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 situations, the system may not
function or its function may be limited.
For example:
- if veh icles 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 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.
(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 au
thorized Audi Service Facility check their
function.
@ Tips
- If the window glass in the driver's door
or front passenger's door has been tint ed, the display in the exterior mirror may
be misinterpreted.
