program
App lies to vehicles: with adaptive cruise control
Fig. 85 Opera tin g le ve r: se tt ing th e distanc e
The distance at wh ich 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 estab lished and maintained. This pro
duces a speed-dependent interval. The higher
the speed, the greater the safety interval in
yards (meters) ¢&, .
Setting the distance
.. Tap the switch to display the current set dis
tance¢

will 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 >
adaptive cruise control > 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 distance may briefly be
less than the stored distance. If the vehicle
ahead accelerates, adaptive cruise control will
also accelerate up to the stored speed. The
higher the speed , the greater the d istance
in yards (meters) ¢&,. .The
Distance 3 setting
is recommended.
The distances provided are specified values .
Depending on the driving situation and the
how the vehicle ahead is driving, the actual
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 comfortable.
A WARNING
Following other vehicles too closely in
creases the risk of collis ions and ser ious
personal injury .
- Setting 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
Description
Ap plies to vehicles: with a daptive cruise co ntrol
Fig. 86 Inst rument cluster: app roach wa rning
Aud i braking guard uses radar sensors and a
video camera. It is act ive at speeds above
about 6.2 mph (10 km/h) and also works
within system limits when adaptive cruise contro l is switched off.
On vehicles with adapt ive cruise control and
Aud i side assist (Audi p re sense plus), system
functions also engage when a co llision is im
minent
¢ page 187.
What c an Audi br aking gu ard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes sud
denly or if your own veh icle is trave ling at a
h igh speed and approachi ng a veh icle up
ahead that is moving more slowly . A udi brak
i ng guard does not react if it ca nnot detect
the sit uat ion .
The system advises you of various situations:
- The
distan ce w arn ing 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
ligh t
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
appr oach 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 avo id a co llision
by swerving or brak ing sharp ly. The indicator
light
I and the symbol in the display will
warn you about the danger¢
fig. 86. You
w ill also hear an acoustic signal.
If you do not react fast enough or do not react
at all to the situation, Aud i braking guard w ill
intervene by braking and the message
br aking
guard interv ention
w ill appear.
- If a collis ion is imminent, the system will
first provide an
a cute 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 coll is ion. O n veh icles with
adapt ive cr uise con tro l a nd Aud i side assist
(Audi pre sense plus), the system can brake
w it h increas ing fo rce up to max imum dece l
eration shortly before a sensed collision
¢page 187.
- If
the Audi braking guard senses that you
are not braking 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
t imely warnings. The system reaction time de
creases automat ically in some situations, for
example when it detects acce lerator pedal use
or steering input. The Audi braking guard in
tervent io n stops in certa in situations, for ex
amp le if you p ress the accele ra to r pedal to
pass the vehicle moving a head of you in your
lane.
Which function s can be controlled?
You can switch Aud i brak ing guard and the
distance/approach warning on or off in the
MM I ¢page 85, Settings in the MMI.
Adaptive cru ise co ntrol and b rakin g guar d 85
& 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 Aud i braking guard is
switched on. Be ready to intervene and
be ready to take complete 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 wi ll not respond outs ide the system
l imits, for examp le when approaching a
stopped vehicle or s tationary obstacle
(end of a traffic jam or vehicle that has
broken down in traffic).
- Always remember that the radar sensor
for the A udi 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 al l.
- Reflective surfaces includ ing crash barr i
ers or tunnel entrances may impair the
function of the radar sensor .
(j) Tips
Lack of attention can cause coll is ions, oth
er accidents and ser ious persona l injuries.
- You can stop the Audi braking guard in-
tervention w ith increas ing braking force
by applying the b rakes yourself or by ac
ce lerat ing rapidly.

Safety tips
Applies to vehicles: with side assist
T he side assist detection may be limited when
driving around narrow street corners, on hi lly
streets, and under poor weather conditions.
It is possible that the radar sensors may a lso
detect other objects, s uch as high or stag
gered guardrails .
S ide assist does not measure act ual lane
width. The system assumes a fixed lane width.
Detection in the left and right lanes is based
on this ass umed lane width . When driving on
narrow roads or when driving to the left or
right of the center of a travel 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 coll is ions and serio us pe r
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.
