A WARNING
Following other vehicles too closely increases
the risk of collisions and ser ious personal in­
jury.
- Setting short distances to the traffic ahead
reduces the time and distance available to
br ing your vehicle to a safe stop and makes
it even more necessary to pay close atten­
tion to traffic.
- Always obey applicable traffic laws, use
good judgment, and select a safe following
distance for the traffic, road and weather
conditions.

Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise contro l
Fig. 122 In strument cluste r: appro ach warning
Braking guard uses a radar sensor. It also func­
tions within the limits of the system when adap­
tive cruise control is switched off .
What can Audi braking guard do?
When detected in time, the system can assess
si tuation s when a veh icle ahead brakes suddenly
or if your own vehicle 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 situat ion.
The system advises you of variou s 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 .
in the display 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 given, it may only be pos­
s ib le to avo id a collision by swerving or braking
sharply. The indicator light . and indicator in
the d isplay will warn you about the danger
¢fig. 122. You will also hear an acoustic signal.
If you do not react fast enough or do not react at
a ll to the situation, Braking guard will intervene
by braking and the message
braking guard inter­
vention
will appear.
l) This is no t a vail able in som e coun trie s.
104
- If a collision is imminent , the system will first
provid e an
acute warning by briefly and sharply
app lying the b rakes.
- If you do not react to the acute warning, brak­
ing guard can brake within the limits of the sys ­
tem . This reduces the vehicle speed in the event
of a collision.
- At speeds under 20 mph (30 km/h), the system
can initiate a complete deceleration shortly be­
fore a collision ll.
- If the braking gua rd senses that you are not
braking hard enough when a collision is immi­
nent, it can increase the braking force.
Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the radio or MMI
¢page 105, Settings in the radio/MM!.
A WARNING
Lack of attent ion can cause collisions, other
accidents and ser ious personal injuries . The
braking guard is an assist system and cannot
prevent a collision by itself . The driver must
always inte rvene. The driver is always respon­
sible for braking at the correct 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 .
- Braking guard works within 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
fic) .
- 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 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

(D Tips
- You can cancel the braking that is initiated
by the system by braking yourse lf, by accel ­
erating noticeably or by swerving.

The display in the left exterior mirror provides as­
sistance when making a lane change to the left,
while the d isp lay in the right exterior mirror pro ­
vides assistance when making a lane change to
the right .

Fig. 126 Rear of the veh icle: pos it ion of the sensors
Side assist functions at speeds above approxi­
mately 19 mph (30 km/h).
@ Vehicles that are approaching
In certain cases, a vehicle will be classified as
critical 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
108
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
(15 km/h)), the display in the exterior mirror
turns on as soon as the vehicle enters your blind
spot .
The display wi ll not turn on if you quickly pass a
vehicle that side assist has detected (the differ­ ence in speed between the vehicle and your vehi­
cle 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 situations, the dis­
play in the exterior mirror may turn on even
though there is no vehicle located in the area
that is crit ical 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 anoth­
er lane that is
not adjacent to your current lane.
- if you are driv ing 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 rails) .
- In poor weather conditions. The side ass ist
functions are limited.
Do not cover the radar sensors
c:> fig. 126 with
stickers, deposits, bicycle wheels or other ob­
j ects, because this w ill affect the function . Do not
use side assist when towing a trailer. For infor­
mation on cleaning, refer to
c:> page 193.
A WARNING
- Always pay attention to traff ic and to the
area around your vehicle. Side assist cannot
replace a driver's attention . The driver alone
is always responsible for lane changes and
-
similar driving maneuvers . IJ>-

-Improper reliance on the side assist system
can cause collisions and serious personal 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 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 authorized
Audi Service Facility check their function.
(D Tips
-If the window glass in the driver's door or
front passenger's door has been tinted , the
display in the exterior mirror may be misin­
terpreted.
