program
App lies to vehicles: with adaptive cruise control
Fig. 89 Opera ting lever: set ting the distance
The distance at which the adaptive cruise con­
trol fo llows a vehicle in front is determined by
time intervals. A time interval to a vehicle in
front is established and maintained. This pro­
duces a speed-dependent interval. The higher
the speed, the greater the safety interval in
yards (meters)
i::> ,& .
Setting the distance
• Tap the switch to disp lay the current set dis­
tance

• To increase or reduce the distance by incre­
ments , tap the switch again to the left or
right . The distance between the two vehicles
wi ll change in the instrument cluster dis­
play.
Setting the driving program
• Select in the MMI:
!CAR I function button>
Car Systems control button > Driver assist>

> Driving program .
Setting the distance
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. When this
happens , the actual d istance may briefly be
less than the stored distance.
If the vehicle
ahead accele rates, adaptive cruise control will
also accelerate up to the stored speed. T
he higher the speed, the g reate r the distance
in yards (meters)

is recommended.
T he distances provided are specified va lues .
Depending on the driving situation and the
how the vehicle ahead is driving, the actua l
distance may be more or less than these tar­
get distances .

Setting the driving program
You can select Dynamic , Standard or Comfort
driving programs. Depending on the selected
driving program and distance, driving behav ­
ior when accelerating wi ll vary from dynamic
to comfortab le.
A WARNING
Following other vehicles too closely in­
creases the risk of collis ions and ser ious
personal injury .
- Sett ing short distances to the traffic
ahead reduces the time and distance
availab le 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 distance for the traffic, road and
weather conditions.

Audi braking guard
Descript ion
Applies to vehicles: with adaptive cruise contro l
Fig. 90 Instrument cluster: approach warning
Audi braking guard uses radar sensors and a
video camera. It is active at speeds above
about 6.2 mph (10 km/h) and also works
within system limits when adaptive c ruise
control is switched off.
On vehicles w ith adaptive cru ise control and
Audi side assist (Aud i pre sense plus), system
functions also engage when a collision is im­
minent
c::> page 182.
What can Audi braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes sud­
denly or if your own veh icle is traveling at a
h igh speed and approaching a veh icle up
ahead that is moving more slowly . Audi brak­
in g guard does not react if it cannot detect
the situation.
The system advises you of various s ituations:
- 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 coll is ion . The ind icator
light
I in the disp lay comes on. Take imme- diate action to avoid
the collision and in­
crease the distance to the vehicle up ahead.
- The
approach warning is given when a de­
tected vehicle up ahead in your lane is mov­
ing much more slowly that you are or if it
brakes sharp ly. When this warning is given,
it may only be possible to avoid a collision
by swerving or braking sharply. The indicator
light
I and the symbol in the display will
warn you about the danger
c::> fig . 90 . You
w il l also hear an acoustic signal.
If you do not react fast enough or do not react
at all to the situation, Audi braking guard w ill
intervene by braking and the message
braking
guard intervention
will appear.
- If a collision is imminent, the system will
first provide an
acute warning by braking
sharply.
- If you do not react to the acute warning, Au­
di braking guard will brake w ith increased
force in severa l stages to reduce the speed
in a poss ible collis ion. On veh icles with
adaptive cruise control and Audi side assist
(Audi pre sense plus), the system can brake
with increasing force up to maximum dece l­
eration shortly before a sensed collision
c::>page 182.
-If the Audi braking guard senses that you
are not brak ing hard enough when a colli­
sion is imminent, it can increase the braking
force.
Audi braking guard takes the driver's reaction
time into consideration in order to provide
timely warnings. The system reaction time de­
creases automatically in some situations, for
example when it detects acce lerator pedal use
or steering input . The Audi braking guard in­
tervent ion stops in certa in situations, for ex­
amp le if you press the accelerato r pedal to
pass the vehicle moving ahead of you in your
lane .
Which functions can be controlled?
You can switch Audi braking guard and the
distance/approach warning on or
off i n the
MM I ¢ page 86, Settings in the MMI.

& WARNING
The Audi braking guard is an assist system
and cannot prevent a collision by itself.
The driver must always intervene . The driv­
er is always responsible for braking at the
correct time.
- Always pay close attention to traffic, even when the Audi braking guard is
switched on. Be ready to intervene and
be ready to take comp lete control when­
ever necessary. Always keep the safe and
legal distance between your vehicle and
vehicles up ahead.
- Audi braking guard works within limits
and w ill not respond outs ide the system
limits, for examp le when approaching a
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 Audi 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 promptly detected or may not be de­
tected at all.
- Reflective surfaces includ ing crash barr i­
ers or tunnel entrances may impair the
function of the radar sensor .
(D Tips
Lack of attention can cause coll is ions, oth­
er accidents and ser ious personal injuries.
- You can stop the Audi braking guard in- tervention w ith increas ing braking force
by applying the brakes yourself or by ac­
celerat ing rapidly .

Side assist uses radar sensors (not visib le on
outside)¢
fig. 91 to help the driver check
blind spots, and see what is happen ing in traf­
f ic beh ind the vehicle¢
page 89, fig. 93.
Signa l lights are built into both o utside mir­
rors ¢
fig. 92. The s ignal light on the left out­
side mirror assists when moving over into the
left lane and the signal light on the right out­
side mirror assists when moving over into the right lane.
The s ignal light comes on to tell you that side
assist has detected a vehicle on that side and
that the position of this othe r vehicle should
be taken into account if yo u were to change
l anes . This is called the
informati ona l stag e
s ignal ¢
page 90. The informational stage
signal is designed so that you notice it only
when you are look ing in the ou ts ide mirror. When you activate the turn signal and side as­
sist detects a vehicle in a notable location, the
corresponding signal on the outside mirror
¢ fig. 92 (!) flashes br iefly and brightly sever­
al times. This is the

- Side assist cannot detect vehicles in time
to a le rt you when they ap proa ch from
be hind at very hig h spee d, or fall drop
back very q uickly.
- The radar sensor's
vision ca n be reduced
or entire ly blocked by rain, snow, and
heavy spray . This can resu lt in side assist
not adequately detecting vehicles or, in
some cases, not detecting them at all.
Always keep an eye on the direction you are traveling and the relevant area
around the vehicle .
- Please note that side ass ist indicates
there are approaching vehicles, or vehi­
cles in your blind spot, o nly after you r ve­
h icle has reach ed a driv ing speed of at
least 19 mph (30 km/h). ..,

you do not adversely affect the way side assist
functions, foreign objects (such as stickers or
b icycle racks) should not be attached to the
a rea on the rear bumper where the sensors
are located. If side assist functions are ad­
versely affected, you will see this message in
the instrument cluster display. Remove any ­
thing that may be blocking the sensors .

If there is a temporary problem (such as the
ve hicle's battery charge being low), s ide ass ist
cannot be activated tempo rari ly.
Audi side assist: system fault
Have the system checked by an authorized Au­
di dealer or qualified workshop.
Audi side assist: not available when
towing
T he radar senso r's view is limited when tow­
ing a trai le r. For vehicles with a fa ctory instal ­
led towing hitch or a trailer hitch that was in­
stalled later according to factory specifica­
tions, side assist is automatically deactivated
as soon as the electrical connection to the
trailer's electrical socket is made, and this sta­
tus message appears in the instrument clus ­
ter display . Deactivation cannot be guaran­
teed when using a retrofitted towing hitch
that was
not installed according to factory
specifications.
Safety tips
Appl ies to vehicles : wi th side assist
The side assist detection may be limited when
driving aro und narrow street corners, on hilly
streets, and under poor weather cond itions.
It is possible that the radar sensors may also
detect other objects, such as high or stag­
gered guardrails .
Side assist does not measure actual lane
width. The system assumes a fixed lane width.
Detection in the left and right lanes is based
o n this ass umed lane width . When driving on
narrow roads or when driving to the left or
right of the center of a trave l lane, it is poss i­
ble that vehicles will be detected that are
not
in the lane next to the lane you are using.
A WARNING
- Improper reliance on the side assist sys­
tem can cause collis ion s and serious per­
sonal 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! ..,.

Pedestrian detection depends on the differ­
ence in temperature between the person and
the background. Pedestr ians may not be de­
tected if the temperature difference is too small . T he pedestrian high ligh ting feature is
deactivated at temperatures above 77 °F (25
°C) and when it is light outs ide.
A WARNING
-
Night vision assistant has limits and can­
not always detect pedestrians. Always pay
close attention to traffic and the area
around your vehicle even when night vision
assistant is sw itched on .
- Night vision assistant can only warn
about people located within the visual
range of the infrared camera. The visual
range corresponds to the image in the in­
strument cluster display.
- Night vision assistant may not detect
peop le and highlight them if

a parked vehicle.
{D) Tips
- Pedestrian detection and the pedestrian
warming are lim ited to objects that are
detected as pedestrians. The system
does not detect animals. Even though
the shape and warmth radiated by each
object detected is evaluated, the system
does have limitat ions and it can give in­
correct warnings.
