General  information 
Your veh icle is primar ily intended  for  transport
ing  people  and  luggage.  However,  if you dr ive 
with  a trailer , follow  the  technical  requirements, 
the  operation  and  driving  tips, and  the  legal  reg
u lations. 
Driving  with  a trailer  affects  the vehicle 's fuel 
consumption,  performance  and  wear.  It also  re
quires  highe r concentration  from  the  driver. 
A WARNING 
Do not  transport  any people  in a trailer  due  to 
the  risk  of  fatal  injury. 
Technical  requirements 
Certain requirements  must  be  met  when  towing 
a trailer. 
Trailer  hitch 
Only use  a trailer  hitch  with  a removab le ball 
hitch  mount  and  ball hitch. The  trailer  hitch  must 
be  perm itted  for  the  vehicle,  the  trailer  and  the 
permitted  total weight  of the  trailer  being 
pu lled.  Above all,  it must  be secure ly and  safe ly 
attached  to  the  vehicle  trailer. 
Never mount  a trailer  hitch  on the  bumper.  The 
trailer  hitch  must  be  mounted  in a way  that does 
not  impair  the  function  of the  bumper.  Do not 
make  any changes  to  the  exhaust  system  and  the  
brake  system. 
Check regularly  if the  trailer hitch  is securely 
mounted.  A lways follow  the  instructions given  by 
the  trai ler  hitch  manufacturer . 
Trailer  brakes 
If the  tra iler  has  its  own  brake  system,  then  fol
l ow  the  manufacturer  specifications.  However, 
the  brake  system  on the  trailer must  never  be 
connected  to  the  vehicle  brake  system. 
Trailer  towing 
Engine  cooling  system 
Driving with a trailer  means a higher  load  on  the 
engine  and the cooling  system.  The coo ling sys
tem  must  be designed  for  additiona l load  and 
contain  enough  coo lant 
i::> @ . 
@ Note 
Longer  inclines  cannot  be  driven  without  a 
suitab le cooling  system,  especia lly if t he out
side  temperatures  are  high . otherwise,  this 
increases  the risk of  engine  damage. 
Operating  instructions 
Several  things  must  be  noted  when  towing  a 
trailer. 
Towing  capacity 
Your vehicle  can  only be operated  with  class  1 or 
class  2 trailers. 
Load distribution 
Poor cargo  load and  distribut ion  can  negatively 
impact  vehicle  handling. 
- Store  objects  preferably  in the  vehicle  luggage 
compartment . The vehicle  should  always  carry 
the  heaviest  poss ible  load  and  the trailer 
should  have the  lightest possible  load. 
- Distribute  the load  in  the trailer  so that  the 
heavy objects  are  as  close  to  the  axle  as  poss i
b le. 
- Secure  objects  from  sl iding  out  of  place . 
- Ut ilize the  maximum  permitted  tongue  weight 
if possible . 
Tires 
Set  the  tire  pressure on your vehicle  for a "full 
load";  see  the  tire  pressure  sticker 
c::>page 215. 
If  necessary,  also  adjust the  tire  pressure  on  the 
trailer  according  to  the  manufacturer's  recom mendat ion . 
Winter  tires  should  be  mounted  on  the  vehicle  and  on the  trailer  during  winter  temperatures. 
Outside  mirrors 
If you cannot  see  the  tra ffic  behind  the  trailer 
with  the  standard  exterior mirrors,  then  you 
81  
Page 84 of 274

Trail er  to wing 
must  attach  additiona l exterior  mirrors . Adjust 
them  so  you  have  a  sufficient  visibility  behind 
you . 
Exterior  lighting 
Follow  the  lega l regulat ions  regard ing  the  light 
ing  eq uipment  on  your  trailer . Conta ct  an  author 
ized  Audi  dealer  or  authorized  Audi  Service  Facili
ty  for  more  information. 
Before  start ing  to  drive,  check  a ll l ight ing  equip
men t on  the  hitc hed  trailer. 
The  headlig ht  range  contro l adjusts  automatical
ly to  the  light  range  of  the  headl ights. 
Safe ty chain s 
Make  sure  the  safety  chains  are  correctly  applied 
when  pulling  a trailer . The  chains  should  hang 
enough  so  t hat  the  trailer  can  dr ive  around 
curves.  However,  they  must  not  touch  the  
g round . 
Air  su spension 
Applies  to:  vehicles  with  air suspension 
The air  suspension  must  be at the  standard  vehi 
cle  height  before  you  set  the  tongue  weight  on  
the  trailer  a nd  h itch  the  trailer ¢@ , 
¢page 107, 
Raising/lowering  the  vehicle. 
For  ve hicles  w ith  a factory-installed  tra iler  hitch, 
the  air  suspension  trailer  mode  will  automat ically 
sw itch  on  if  you  connect  the  trailer  cable  to  the 
socket. 
For  ve hicles  w ith  a  retrof itted  trailer  hitch,  you 
must  switch  on  the  air  suspension  trailer  mode 
manually . Select  in the  Infota inment  system: 
ICARI function  button > ( Car )*  s yste m s contro l 
button 
> V ehicle  setting s > Air su spen sion : trail 
e r >  On . 
Switch  it  off  again  after  tow ing  a  tra ile r. 
You can  also  switch  off  tra iler  mode  ma nually 
while  driving,  for  example,  when  using  a  bicycle  rac k system . 
If you  have  to  drive  through  difficult  road  condi
tions,  you  can  raise  the  vehicle  aga in  after  hitch
ing  the  t rai ler  or  after  adjust ing  the  tongue 
weight . 
82 
@ Note 
Applies  to: vehicles  with  air  suspension 
-Changes  i n temperature  or  load  can  affect 
the  height  of  the  vehicle . 
- Set  the  air  suspension  to  the  standard  veh i
cle  he ight,  otherwise  the  applicable  tongue 
we ight  no  longer  appl ies  to  your  veh icle. 
(D Tips 
- Use  chocks  when  park ing  on  inclines  if the 
trai ler  is loaded. 
- We  recommend  also  hav ing  the  vehicle  in
spected  between  the  inspection  intervals  if 
you  are  towing  a trailer  frequently. 
- Avoid  driv ing  with  a  trai ler  dur ing  the  veh i
cle  break-in  per iod. 
Driving  with  a trailer 
Driving with  a  trailer requires  extra  caution. 
Sp eed 
Adhere  to  t he  lega l speed  lim its . Fo llow  the  legal 
regu lations 
specific to  the  country. 
As the  speed  increases,  the  dr iv ing  stab il ity  of 
t h e tra ile r decreases.  Therefore  you  should  not 
exceed  the  max imum  lega l speed  lim it  w hen 
t h ere  are  unfavorab le  road,  weather  and/or  wind 
conditions.  This especia lly applies  when  driving 
downh ill. 
Yo u m ust  always  red uce your  speed  as  soon  as 
you  notice  even  the  slightest  swinging  motion  o f 
the  trai ler . Never  try  to  "straighten  out"  the  trai l
er  by  acce lerating. 
The  we ight  d istr ibution  is very  poor  if the  vehicle 
is empty  and  the  trai ler  is  loaded.  However  if you 
must  drive  under  these  circumstances,  then  drive  
especially  slowly . 
Brakes 
B rake  in a  time ly  manner.  Downs hift  befo re  dr iv 
i ng  down hill so  that  the  engine  can  assist  with 
braking ¢&. . 
When  using  a trailer  w it h  over run  bra kes,  fi rst 
bra ke  gently  t hen  q uick ly.  This red uces  the  r isk  of 
j erking  while  braking  if the  trailer  wheels  lock  up .

Speed  warning  system 
Description 
Applies  to:  veh icles  with  speed  warning  system 
The speed  warning  system  helps you  to  stay un
der a  specified  maximum  speed. 
The  speed warning  system warns  you  if you are 
exceeding  the  maximum  speed  that you  have set. 
A warning  tone  will  sound  as  soon as your speed 
exceeds the  sto red value slightly. 
The . (USA models) I. (Canada models)  indi
cator  light  and a message appear  in  the  instru
ment  cluster  display  at the  same  time. 
The. 
• indicator  light  and the  message turn  off  if  the 
speed falls  back below  the  stored  maximum  
speed.  
Sett ing  a threshold  is recommended  if you would 
like to  be reminded  when  you  reach a certa in 
maximum  speed.  S ituations  where  you  may want 
to  do so i nclude  driving  in  a country  wit h a ge ne r
a l speed limit  o r if  the re  is a specified  maximum 
speed for  winter  tires.

Assistance systems 
-With  stationary objects ¢ page 89. 
A WARNING 
Always  pay  attention  to  traffic  when  adaptive 
cruise  control  is switched  on  and  braking  
guard  is active.  As the  driver,  you  are  still  re
sponsible  for  starting  and  for  maintaining  
speed  and  distance  to  other  objects.  Braking  
guard  is used  to  assist  you . The  driver  must 
always  take  action  to  avoid  a collision.  The  
driver  is always  responsible for  braking  at  the 
correct  time. 
- For  safety  reasons, do  not  use  adaptive 
cruise  control  when  driving  on  roads  with 
many  curves,  when  the  road  surface  is  in 
poor  condition  and/or  in  bad  weather  (such  
as  ice,  fog,  gravel,  heavy  rain  and  hydroplan
ing).  Using  the  system  under  these  condi
tions  increases  the  risk  of  an  accident. 
- Switch  adaptive  cruise  control  off  tempora
rily when  driving  in turning  lanes, on  ex
pressway  exits  or  in construction  zones. This 
prevents  the  vehicle  from  accelerating  to 
the  stored  speed  when  in these  situations . 
- The  adaptive  cruise  control  system  will  not 
brake  by  itself  if you  put  your  foot  on  the  ac
celerator  pedal.  Doing  so  can  override  the 
speed  and  distance  regulation. 
- When  approaching  stationary  objects  such 
as  stopped  traffic,  adaptive  cruise  control 
will  not  respond  and  braking  guard  will  have  limited  function. 
- The  adaptive  cruise  control  system  and 
braking  guard  do  not  react  to  people,  ani
mals,  objects  crossing  the road  or  oncoming 
objects. 
- The  function  of  the  radar  sensors  can be af
fected  by  reflective objects such as  guard 
rails,  the  entrance  to  a tunnel,  heavy  rain  or  
ice. 
A WARNING 
- Improper  use of  adaptive  cruise  control  can 
cause  collisions,  other  accidents  and  serious  
personal  injury. 
- Never  let  the  comfort  and  convenience  that 
adaptive  cruise  control  and  braking  guard 
88 
offer  distract  you  from  the  need  to  be  alert 
to  traffic  conditions  and  the  need  to  remain 
in full  control  of your  vehicle  at  all  times, 
- Always  remember  that  the  adaptive  cruise  
control  and  braking  guard  have  limits  -they 
will  not  slow  the  vehicle  down  or  maintain  the  set  distance  when  you  drive  towards  an  
obstacle  or  something  on  or  near  the  road  
that  is not  moving,  such  as  vehicles  stopped 
in a traffic  jam,  a  stalled  or  disabled  vehicle. 
If  registered  by the  radar  sensors,  vehicles 
or  obstacles  that are  not  moving  can  trigger 
a  collision  warning  and  if confirmed  by the  
video  camera,  an  acute  collision  warning. 
- Never  follow  a vehicle  so  closely that  you 
cannot  stop  your  vehicle  safely.  The  adap 
tive  cruise  control  cannot  slow  or  brake  the 
vehicle  safely  when  you  follow  another  vehi cle  too  closely.  Always  remember  that  the  
automatic  braking  function  cannot  bring  the 
vehicle  to a  sudden  or  emergency  stop  un
der  these  conditions . 
- To prevent  unintended operation,  always 
switch  ACC off  when  it  is not  being  used . 
@ Note 
The  sensors  can  be  displaced  by  impacts  or  
damage  to the  bumper,  wheel  housing  and 
underbody.  That  could  affect  the  adaptive 
cruise  control  system  and  braking  guard . 
Have  an  authorized  Audi  dealer  or  authorized 
Audi  Service  Facility  check  their  function.

When  detected  in time,  the  system  can  assess 
dangerous  sit uat ions  where  an  object  a head 
brakes  suddenly  or  if your  own  vehicle  is traveling 
at  a  high  speed  and  approaching  an  object  that  is 
mov ing  more  slowly.  The  brak ing  guard  does  not 
react  if it cannot  detect  the  situation. 
The  system  advises  you  of  various  dangero us sit
uations : 
- T he 
distan ce warning occurs  if you  d rive  too 
closely  to  the  object  ahead  for  a  long  period  o f 
time . If  the  object  ahead  brakes  strongly,  you 
would  not  be  able  to  avoid  a collision . 
The. 
indicator  light  appears  as  an  indication  for  th is. 
- The 
app roach  wa rning occurs  when  an  object 
ahead  is traveling  more  s low ly or  brakes 
strongly.  When  th is warning  occurs,  it  may  on ly 
be  poss ible  to  avoid  a  co llision  by swerving  or 
braking  strongly . The  danger  is indicated  by the 
• ind icator  light ~ fig . 99 . An aud io signal  w ill 
also  sound . 
If you  do  not  react  early  enough  or  at  a ll to  a  dan
ge rous  situation,  the  braking  guard  suppo rts  you 
w ith  a  brak ing  intervent ion . 
- If  a  co llision  is  imminent,  the  system  will  first 
provide  an 
ac ute  warning by  braking  sharply. 
- If you  do  not  react  to  the  acute  warning,  the  braking  guard  can  increase  the  braking  force 
within  the  limits  of  the  system 
ll . Th is  reduces 
the  veh icle  speed  in the  event  of  a  collision . 
- The  system  can  init iate  comp lete  decelerat ion 
shortly  before  a collision 
l l. Full deceleration  at 
high  speeds  occurs  only  in vehicles  with  adap
t ive  cru ise  control  and  s ide  ass ist  (pre  sense 
plus). 
- If  the  braking  gua rd  determines  that  you  are 
not  brak ing  st rongly  eno ugh  whe n there  is  an 
i mpending  co llision,  i t can  increase  the  brak ing 
fo rce .

A WARNING 
--
Lack of  attention  can  cause  collisions,  other 
accidents  and  ser ious  personal  inj uries.  The 
braking  guard  is a n assist  system  and  cannot 
pr event  a collision  by  itself . T he  dr iver  m ust 
a lways  inte rvene . The  d river  is  always  respon
s ib le  for  b raking  at  the  co rrect  t ime. 
- Always  pay  close  atten tion  to  traffic,  even 
when  the  b raking  gua rd  is switched  on.  Be 
ready  to  in tervene  and  be  rea dy  to take 
comp le te  co ntro l wheneve r ne cess ary. A l
ways  keep  the  sa fe  and  legal  distance  be 
tween  your  vehi cle  a nd  ve hicl es  up  ahead . 
- B raki ng  g uard  works  w it hi n limi ts a nd  will 
not  respond  o uts ide the  system  limits,  fo r 
examp le when  approach ing  a  stopped  veh i
cle  or  stationary  obstacle  (end  of  a traff ic 
jam  or  vehicle  that  has  broken  down  in traf 
fic). 
- Always  remember  that  the  radar  sensor  for 
the  brak ing  guard  works  only  within  def ined 
detection  and  range  limits  that  may  prevent  
the  proper  detect ion  of  other  vehicles. 
- The  radar  sensor's  function  and  range  can 
be  reduced  by  rain,  snow  and  heavy  spray.  
Mov ing  vehicles  up  ahead  may  not  be 
promptly  de tected  or  may  no t be  detected

Audi  active  Lane  assist 
Description 
Appl ie s  to: ve hicles w ith  Audi  active  lane assis t 
Active lane  assist  det ects  lane  mark er lines with
in the  limits  of the  system  using a came ra in the 
windshie ld.  If you are  approaching  a detected 
lane  marker  line and  it appears  likely that  you 
w ill leave the  lane , the  system  will warn you w ith 
correct ive steer ing . You can override t his steer ing 
at  any t ime . If yo u pass  over a line, t he s teer ing 
wheel  will v ib rate  l igh tly.  In o rder  for this  wa rn 
ing v ib ra tion to  occur,  i t mus t first  be sw itche d 
on in the  Info tainmen t sys tem . Act ive  lane  assist 
is ready for operation  when  the  lane  marke r line 
is detected  on at  least  one side  of the  vehicle. 
T he  system  is designed  fo r driving on express 
ways and  highways and  therefore  only activates 
at  speeds  above approximate ly 40  mph  (65  km/ 
h). 
A pp lies to:  ve hicles w ith  s ide ass ist 
If  yo u ac tiva te a turn  signa l when  active  lane  as 
sist  is ready and  it classifies  a  lane  change  as  crit 
ical because  of ve hicles traveling  a longside  you or 
approaching  you, there  will be  noticeab le correc-
96 
tive steer ing sho rt ly befo re yo u leave the  lane. 
This wi ll attempt  to  keep your ve hicle in the  lane. 
App lies  to: vehicles wi thout  s ide assis t 
The system  will not  warn  you befo re cross ing a 
l ane  mar ke r li ne  if you have act ivated  the  t urn 
s ignal.  In this case,  it  assumes  that  you are 
c h anging  lanes  intentionally. 
App lies to:  vehicles wit h adaptive  c ruise contro l 
The corrective steering  is targeted  based  on the 
driv ing situation . In add ition  to  the  lane  ma rke r 
li nes , the  system  can a lso take  into  account  other 
objects  such as  guard  rails . If they  are  detected  in 
close  prox imity to  the  ve hicle, act ive  lane  ass ist 
helps  p reve nt  the  vehicle from  dr iv ing too  close 
to  t hem.  The re is a lso  pass ing ass ista nce.  The 
system  does  no t provide any co rrec tive steering  if 
i t  detects  that  you are  pass ing anot her vehicle. 
A WARNING 
- The system  warns  the  drive r that  the  vehicle 
is  leaving the  lane  using cor rect ive steering. 
The d rive r is always respons ible fo r keeping 
the  vehicle within  the  lane. 
- The system  can help you  keep  the  vehicle  in 
the  lane,  b ut  it does  not  d rive by itse lf. Al
ways  keep your ha nds  on the  steering 
wheel. 
- Cor rective steering  may not  occur in certain 
situations,  such  as d uring heavy braking . 
- There  may be cases  where  t he camera  does 
not  recognize  all  la n e mar ker  lines.  Correc
tive steering  can only take  place on  the s ide 
of the  vehicle where  lane  ma rker lines are 
detec ted . 
- Othe r road  str uctures  or objects  could  poss i
b ly be  identified  u nintent ionally as  lane 
ma rker lines. As  a res ult,  co rr ec tive stee rin g 
m ay  be u nexpec ted  o r m ay n ot occur . 
- The camera  view ca n be  res tricted,  fo r ex
a mp le by ve hicles  dr iving ahea d or by r ain, 
snow,  he avy spray or  lig ht  shin ing into  t he 
camera.  This can  resul t  in a ctive  lane  ass ist 
not  detecting  the  lane  ma rke r lines o r de
tect ing them  inco rrectly.

Side  assist  functions  at  speeds  above  app roxi
mately  19  mph  (30  km/h). 
@ Vehicles that  are  appro aching 
In  certain  cases,  a vehicle  will  be  classified  as  
cr itical  for  a  lane  change  even  if  it  is still  some
what  far  away.  The  faster  a veh icle  app roaches , 
the  sooner  the  d isplay  in the  exterio r mirror  w ill 
turn  on . 
@ Vehicles traveling  with  you 
Vehicles  traveling  with  you  are  ind icated  in the 
exterior  m irror  if they  are  classified  as  critical  for 
a  lane  change.  All vehi cles  detected  by side  assist 
100 
are  indicated  by the  time  they  enter  your  "blind  
spot",  at  the  latest . 
© Vehicle s you are passing 
If you  slow ly pass  a  vehicle  that  s ide  assist  has 
detected  (the  difference  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  w ill not  turn  on  if you  quickly  pass  a 
vehicle  that  side  ass ist  has  detected  (the  differ
ence  in speed  is greater  than  9  mph  (15  km/h)) . 
Functional  limitations 
The  radar  sensors  are  designed  to  detect  the  left  
and  rig ht  adjacent  lanes  when  the  road  lanes  are 
the  norma l width.  In  some  si tuations,  the  display 
i n the  exterior  m irror  may  turn  on  even  though 
there  is  no vehicle  located  in the  area  that  is criti
ca l for  a  lane  change.  For  example: 
- If  the  lanes  are  narrow  or  if you  are  dr iving  on 
the  edge  of you r lane . If th is  is the  case,  the 
system  may  have  detected  a  vehicle  in another 
lane  that  is 
not adjacent  to  your  current  lane. 
- If you  are  d riving  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  disp laced  guard  rai ls) . 
- In  poor  weather  conditions.  The  side  assist  functions  are  limited . 
Do no t cover  the  rada r senso rs ¢ 
fig. 107 w it h 
stickers,  deposi ts,  b icycle wheels  or  other  ob
jects,  because  they  will impair  the  function . Do 
not  use  side  assist  when  towing  a trai ler.  For  in
format ion  on  cleaning,  see 
¢ page 228. 
& 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  always  responsible  for  lane  changes  and  
sim ila r driv ing  maneuve rs . 
- In  some  situations,  the  system  may  not  function  o r its  function  may  be  limited . For 
examp le:
