2014 AUDI A5 COUPE cruise control

Audi adapt ive crui se c ontrol an d bra kin g guard 91
confirmed by the video camera, an acute
collision warning.
- 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 conditions cou ld result in a co lli­
sion.
- Switch adaptive cruise control off tempo­ rar ily when driving in turning lanes, on
expressway exits or in cons truction
zones. This prevents the vehicle from ac­ celerating to the set speed when in these
situations.
- The adaptive cr uise control system wi ll
not brake by itse lf if you p ut your foot on
the accelerator pedal. Doing so can over­
ride the speed and distance regulation .
- When approaching stationary objects
such as stopped traff ic, adaptive cruise
control will not respond and braking
guard w ill have limited function.
- The adaptive cruise control system and
braking guard do not react to people, an­
ima ls, objects crossing the road or on­
coming objects.
- The function of the radar sensor can be
affected by reflective objects such as
guard rails, the entrance to a tunnel,
heavy rain or ice.
- Never follow a ve hicle so closely that you
cannot stop your vehicle safely. The
adaptive cruise cont ro l cannot slow or
brake the veh icle safely when you follow
ano ther veh icle too closely. Alway s re­
member that the automatic braking
function cannot bring the vehicle to a sudden or emergency stop under these
condit ions.
- To prevent unintended operation, always
switch ACC off when it is not being used.
(D Note
The sensor can be disp laced by impacts or
damage to the bumper, whee l housing and
underbody . That could affect the adaptive cruise control system and braking g
uard.
Have your authorized Audi dea ler o r au­
thorized Audi Service Facility chec k their
funct ion.
In curves
App lies to vehicles: with A ud i ada ptive c ruise contro l
F ig . 91 Example: driving into a curve
When driving into a curve <=.> fig. 91 and ou t of
a curve, the adaptive cruise control may react
to a vehicle in the next lane and apply the
brakes. You can override or prevent the brak ­
ing by pressing the accelerator pedal briefly.
Stationary objects
App lies to vehicles: wit h Audi adapt ive cr uise contro l
F ig . 92 Example : objec t changing lanes an d stationary
object
The adaptive cru ise contro l system only reacts
to objects that are mov ing or that the system
has a lready detected as moving. For examp le,
if a ve hicle@ , which has already been detec t­
ed by the adaptive cru ise con trol , turns or
changes lanes and another stationa ry vehicle
@ is located in front of that vehicle, the sys­
tem will not react to the stationary vehicle.

What can Audi adapt ive crui se cont rol do?
The adaptive c ruise contro l wor ks in con junc­
tion with a radar sensor installed in the front
of the vehicle¢
page 90 , fig . 90, which is sub­
ject to designated system limits
r=> page 92.
Stat ionary objects a re d is regarded .
On open roads w ith no traff ic, adaptive cruise
control works like a reg ular cruise control sys- tern.
The sto red speed is maintained . When
approaching a moving vehicle detected up
ahead, the adaptive c ruise control system a u­
tomat ica lly s lows down to match that vehi­
cle's speed and then maintains the distance
t h at the dr ive r previously stored . As soon as
the sys tem does not detec t a ve hicle up
ah ead, adaptive cru ise cont ro l accelerates
back up to the stored speed.
Which functions can be controlled?
When you switc h adapt ive cru ise control on,
yo u can set the c urrent speed as the ''control
speed " ¢
pag e 93, Switching on and off .
When driving, yo u can stop cru ise contro l

at any time.
You can also set the distance to the object
ahead and set the adapt ive cr uise contro l driv­

A WARNING
Following other vehicles too closely in­
creases the risk of coll is ions and ser ious
personal injury .
- Sett ing short distances to the traffic
ahead reduces the time and distance
available to bring your vehicle to a safe
stop and makes it even more necessary
to pay close atten tion to traffic.
- Always obey applicab le traffic laws, use
good judgment, and se lect a safe follow­
ing d istance for the t raff ic, road and
weather conditions .

What can Audi braking guard do?
When detected in time, the system can assess
s ituations when a vehicle ahea d brakes s ud­
denly o r if your own vehicle is traveling at a
high speed and approach ing a vehicle up
ahead that is moving mo re slowly . Braking
guard does not react if it cannot detec t the
s ituation .
The system advises you of var ious situations:
- The
distance warning is given if yo u are too
close to the vehicle ahead for a long time. If
the vehicle ahead brakes sharp ly , yo u will
not be ab le to avoid a collision . The indicator
light . in the display comes on .
- The
approach warning is given when a de­
tected vehicle up ahead in your lane is mov­
ing m uch more slowly than yo u are or if it
brakes s harply . When t his war ning is given,
it may o nly be poss ibl e to avo id a co llision
by swe rv in g or b ra ki ng s harp ly. The indica tor
