l)_ This  reduces  the  vehicle  speed  in the 
event  of  a collision.  At  low  vehicle  speeds,  pre 
sense  front  can  initiate  a  complete  deceleration 
shortly  before  a  collision  with  a vehicle  driving 
ahead 
1>. If  pre  sense  front  determines  that  you 
are  not  braking  strongly  enough when  a  collision 
is  imminent,  it can  increase  the braking  force . 
The following  functions  trigger  in conjunction 
with  pre  sense  basic/rear at  corresponding  vehi 
cle  speeds : 
- Reversible  tensioning  of  the  front  safety  belts. 
- Closing  the  windows  and  sunroof*. 
- Inflating  the  side  bolsters*  in the  seat  backrest 
and  seat  surface. 
Audi  drive  select*:  the reversible  belt  tensioner, 
the  closing  of the  windows  and sunroof*  as well 
as  the  inflating  of the side bolste rs* on  the  seat

ing  on  the  mode  selected . 
Collision avoidance  assist 
Collision  avoidance  assist  helps  you to steer  the 
vehicle  around  an  obstacle in a  critical  situation. 
If  you  avoid  an  obstacle  after  the  acute  warning, 
then  the  collision  avoidance  supports  you  by ap plying  slight  steering  adjustment  to  correct  your 
steering  wheel  angle  as  long as  you  are  actively 
steering.  Collision  avoidance  assist  is  available  at 
speeds  between  approximately  20  mph  (30  km/ 
h)  and  90  mph  (150  km/h). 
Turn assist 
When  starting  to  drive  and  up  to  speeds  of  maxi
mum  6  mph  (10  km/h),  the  turn  assist  uses  a 
braking  intervention  to  prevent your  vehicle  from 
colliding  with  an  oncoming  vehicle  when  turning  left  or right  (available  in  certain  countries) . The 
braking  intervention  causes  your  vehicle  to  stay 
in  its  lane.

it cannot  prevent  a  collision  in  every  circum
stance.  The  driver  must  always  intervene. 
The  driver  is always  responsible  for  braking 
at  the  correct  time.  Do  not let the  increased 
safety  provided  tempt you  into  taking  risks . 
This  could  increase  your  risk  of a collis ion. 
- The  system  can  deploy  incorrectly  due  to 
system-specific  limits. 
- Please  note  that  the  sensors  and  the  camera

Audi  pre  sense  city 
' Description 
App lies to : vehicles wit h Audi pre  sense city 
Within  the  limits of  the  system,  pre sense city 
can  warn  you  of  impending  collisions  with 
vehicles  and  pedestrians  and  initiate  the applica
ble  braking  maneuver  if  needed. Pre sense city  is 
active  at  a speed of  6  mph  (9  km/h)  and higher. 
A pedestrian  warning  can occur at  speeds up to  50  mph  (85  km/h),  and vehicle  warnings  can oc
cur at  speeds up to  155 mph  (250  km/h).  A pre 
sense city  braking  maneuver  is possible  at  speeds 
up  to  50  mph  (85  km/h). 
Warnings 
App lies to:  vehicles wit h Aud i pre sense city 
The system  recognizes various  dangerous  situa
tions.  The 
early warning occurs when: 
- a vehicle  driving  ahead brakes sudden ly, 
- your  own vehicle  approaches  a sign ificantly 
slower  vehicle  or  stationary  vehicle  in the  direc
tion  of  travel. 
- a pedestrian  is standing  in  the  lane or is moving 
into  the  lane. 
When  this warning  occurs, it may  only  be possi
ble  to  avo id a collision  by swerving  or  braking 
strongly.  The message 
Audi  pre sense. 
~ page 108, fig. 104 and a warning  tone  will 
warn  you about  the  danger. 
Additionally,  a jerk  on the  brakes may occur  as an 
acute  warning when  there  is an  impend ing colli
sion . If  you  do  not  react  to  the  acute  warning,  pre 
sense city  can brake to  the  point of  complete  de
ce leration  within  the  limits of  the  system.  This 
reduces  the  vehicle  speed  in the  event  of  a colli
sion.  The message

Audi  active  Lane  assist 
Description 
Applies  to:  veh icles  w ith  Audi  active  lane assist 
Active  lane  assist  (lane  departure  warning)  de
tects  lane  ma rker  lines  withi n the  l imits  of  the 
system  using  a  camera in the  windshield.  If you 
are  approaching  a  detected  lane  marker  line  and  it  appears  likely that  you  will  leave the  lane,  the 
system  will warn  you w ith  corrective  stee ring . 
You can  override  this  steering  at  any  time . If you 
112 
pass  over a line,  the  steering  wheel  will vibrate 
lightly.  In  order  for  this  warning  vibration  to  oc
cur,  it must  first  be switched  on  in the  Infotain
ment  system.  Active  lane  ass ist  is  ready  for  oper
a tion  when  the  lane marker  line  is detected  on  at 
least  one  side  of  the  vehicle . 
T he  system  is des igned  for driving  on  express
ways  and  highways  and  therefore  on ly activates 
a t  speeds  above  approximately  40  mph  (65  km/ 
h) . 
Applies  to  vehicles  with  s ide ass ist*:  if you  acti
vate  a  turn  signa l when  active  lane  assist  is  ready 
a nd  it  classifies  a  lane change  as  critical  bec ause 
of veh icles  traveling  a longside  you  or  approach 
i ng  you,  there will  be  noticeable  corrective  steer
i ng  shortly  before  you  leave  the  lane. This will  at
tempt  to  keep  your  vehicle  in  the  lane. 
Applies  to  vehicles  without  side  assist* : the  sys 
tem  does  not  warn  when  it  is ready if you  act ivate 
the  turn  signal  before  crossing the lane  marker 
lin e. In  this  case, it  assumes  that you  are  chang
in g lanes  intent ionally. 
Applies  to  vehicles  with  adaptive  cruise  contro l*: 
there  is  no corrective  steer ing or  warnings  if the 
system  recognizes  a distinct  passing maneuver. 
If the  conditions  are  met,  congestion  assist 
switches  on  at speeds  under  approximately 
40  mph  (65  km/h) 
¢page  104. 
_& WARNING 
-The system  warns  the  driver  that  the  vehicle 
is  leaving  the lane  using  correct ive steering. 
The  driver  is  always  responsible  for  keeping 
the  vehicle  within  the  lane. 
- The  system  can  help  you  keep the  vehicle  in 
the  lane,  but  it  does  not  drive by itself. Al
ways  keep your  hands  on  the  steering 
wheel. 
- Corrective  steering  may  not  occur  in  certain 
situations,  such  as  during heavy  braking . 
- There  may  be  cases  where  the  camera  does 
not  recognize  all lane  marker  lines.  Correc
tive  steering  can only  take  place  on  the side 
of  the  vehicle  where  lane  marker lines  are 
detected.  
Page 115 of 386

-Other  road  structures  or  objects  could  possi
bly  be  identified  unintentionally  as  lane 
marker  lines.  As a  result,  corrective  steering 
may  be  unexpected  or  may  not  occur . 
- The  camera  view  can  be  restr icted,  for  ex
amp le  by vehicles  driving  ahead  or  by rain, 
snow,  heavy  spray  or  light  shining  into  the 
camera.  This can  result  in  act ive  lane  assist 
not  detecting  the  lane  marke r lines  or  de
t ecting  them  incorrectly. 
- In  certa in situations  where  v is ibility  is  low, 
th e  vehicle  may  swi tc h  from  an  "early"  to 
" la te"  steering  co rrection . 
- Under  certa in conditions  s uch as  ruts  in the 
road,  an  inclined  roadway  o r crosswinds,  the 
c o rrective  steering  a lone  m ay not  be  eno ugh 
to  keep  the  vehicle  i n the  middle  of the  lane . 
- For safe ty  re asons,  active  la ne  as sis t m ust 
not  be  used  when  the re are  poor  road  and/ 
o r weathe r cond itions  such  as  slippery 
roads,  fog,  grave l,  heavy  rain,  snow  and  the 
potent ial for  hydroplaning . Using  active  lane 
assist  under  these  conditions  may  increase 
the  risk of  a crash.

Assist 
Information stage 
As long as you  do  not  activate the  turn  signal, 
side  assist 
informs you  of  the  vehicles  that  are 
detected  and  classified as  critical.  The display  in 
the  mirror  turns  on,  but  is dim . 
The  display  remains  dim in the  information  stage 
so  that  your  view  toward the  front  is not  distur
bed.

I f the  display  in  a mirror  blinks  br ight ly when  you 
ac tivate  a  turn  signal,  side  assist is

In  certain  cases,  a veh icle  w ill be  classified  as

© Vehicles  you are passing 
If you  slowly  pass  a vehicle  that  side assist  has 
detected  (the  difference in  speed  between  the 
veh icle  and  your  vehicle  is  less than  approximate
ly  9  mph  (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  assist  has  detected  (the  differ
ence  in  speed  is greater  than  approximately  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  some  situations,  the  display 
in the  exterior  mirror  may  turn  on  even  though 
there  is no  vehicle  located  in the  area  that  is criti
cal  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  a vehicle  in another 
lane  that  is 
not adjacent  to  your  current  lane. 
- If you  are  driving  through  a  curve.  Side  assist 
may  react  to  a vehicle  that  is  in the  same  lane 
or one  lane  over  from  the  adjacent  lane. 
- If  side  assist  reacts  to  other  objects  (such  as 
roadside  structures  like guard  rails). 
- In  poor  weather  conditions . The  side  assist 
functions  are limited. 
Do  not  cover  the  radar sensors ¢ 
fig.  112 with 
stickers,  deposits,  bicycle  racks or  other  objects, 
because  this  will  impair their function.  Do not 
use  side  assist  when  towing  a  trailer.  For  infor
mation  on  cleaning,  refer  to¢ 
page  33 7. 
A 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 a lways  responsible  for  lane changes  and 
similar  driving  maneuvers. 
Assist 
-In  some  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  m ist. 
- 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  adversely  affect  the  sys
tem.  Have an  authorized  Audi dealer  or  au
thorized  Audi  Service  Facility  check  their  func
tion. 
(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  incor
rect.
