Audi ada pti ve c ruise contr ol and br akin g gu ard
-For safety reasons, do not use adapt ive
cruise contro l when driv ing on roads with
many curves, when the road surface is in
poor condit ion and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydroplan­
ing) . Us ing the system under these condi­
t ions could result in a collision .
- Switch adaptive cruise contro l off tempora­
rily when driving in turn ing lanes, on ex­
pressway exits or in const ruc tion zones. This
preven ts the vehicle from accelerating to
the set speed when in these situat ions .
- T he adapt ive cr uise con trol system will no t
br ake by i tself if you pu t your foot on the ac­
celerator peda l. Doing so can override the
speed and distance regulation.
- Whe n approaching stat ionary obje cts such
as stopped traffic, adapt ive cruise control
will not respo nd and braking guard will have
limited function .
- The adaptive cruise control system and
brak ing guard do not react to peop le, ani­
ma ls, objects crossing the road or oncom ing
objects.
- The function of the radar sensor can be af­
fected by reflective objects such as guard
rai ls, t he entrance to a tunnel, heavy rain or
ice.
- Never follow a veh icle so closely that you
cannot stop your vehicle safely . The adap­
t ive cr uise control cannot slow or brake the
vehicle safely when you follow another veh i­
cle too close ly. Always remember th at the
au tom atic b raking function ca nnot br ing the
vehicle to a sudden or emergency stop un­
der these conditions .
- T o preven t unintended operation, always
switch AC C off when i t is not be ing used.
(D Note
The sensor can be disp laced by impacts o r
damage to the bumper, whee l housing and
underbody. That co uld affect the adaptive
cru ise con trol sys tem and braking guard.
Have your a uthorized Audi dea ler or author­
ized Aud i Service Facility check their function.
In curves
Applies to vehicles: with Audi adaptive cruise control
Fig. 113 Ex amp le : d ri ving int o a c urve
When driving into a curve¢ fig. 113 and out of a
curve, the adapt ive cruise control may react to a
vehicle in the next lane and apply the brakes . Yo u
can override or prevent the b raking by press ing
the accelerator pedal b riefly.
Stationary objects
Applies to vehicles: with Audi adaptive cruise control
Fig. 1 14 Example: object c hang ing lanes a nd st ationary
ob ject
The adaptive cruise control system only reacts to
objects that are moving or that the system has
already detected as moving. For example, if ave­
hicle @, which has already been detected by the
adaptive cruise control, turns or changes lanes
and another stat ionary vehicle @ is located in
front of that vehicle, the system will not react to
t h e stationary veh icle.
Vehicles with manual transmission

Audi adaptive cruise control and braking guard
When the adaptive cruise control is turned on,
you must press the clutch to shift gears (as usu­
al) . When shifting normally or when press ing the
clutch, the adaptive cruise control remains
turned on.
After you have engaged the gear, you do
not
need to press the gas pedal. The adaptive cruise
control accelerates automatically if necessary.
If you press down on the clutch for too long or
shift/coup le improperly , the adaptive cruise con­
trol may turn off automatica lly.
@ Tips
You cannot turn on the adaptive cruise con­
trol during a shifting operation .

Description
Applies to vehicles: with Audi adaptive cruise control
Fig . 115 De tect ion range
What can Audi adaptive cruise control do?
The adaptive cruise control works in conjunction
with a radar sensor installed in the front of the
veh icle
,::;,page 98, fig. 112, wh ich is subject to
designated system limits
r::;, page 100. Stationary
objects are disregarded.
On open roads with no traffic, adaptive cru ise
control works like a reg ular cruise control sys­
tem. The stored speed is ma inta ined. When ap­
proaching a moving vehicle detected up ahead,
the adaptive cruise cont rol system automatically
slows down to match that vehicle's speed and
then maintains the distance that the driver previ­ ously stored. As soon as the system does not de-
100
tect a ve hicle up ahead, adaptive cruise control
acce lerates back up to the stored speed.
Which functions can be controlled?
When you switch adapt ive cru ise control on, you
can set the current speed as the "control speed"
9 page 100, Switching on and off.
When dr iving, you can stop cruise control
9 page 102 or change the speed r::;, page 101 at
any time .
You can also set the distance to the object ahead
and set the adaptive cruise control driving pro­
gram

it even more necessary to pay close atten­
tion to traffic.
- Always obey applicable traffic laws, use
good judgment, and select a safe following
distance for the traffic, road and weather
conditions.

Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise contro l
Fig. 122 In strument cluste r: appro ach warning
Braking guard uses a radar sensor. It also func­
tions within the limits of the system when adap­
tive cruise control is switched off .
What can Audi braking guard do?
When detected in time, the system can assess
si tuation s when a veh icle ahead brakes suddenly
or if your own vehicle is traveling at a high speed
and approaching a vehicle up ahead that is mov ­
ing more slowly . Braking guard does not react if
it cannot detect the situat ion.
The system advises you of variou s situations:
- 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 collision. The indicator light .
in the display comes on.
- The
approach warning is given when a detected
vehicle up ahead in your lane is moving much
more slowly than you are or if it brakes sharply .
When this warning is given, it may only be pos­
s ib le to avo id a collision by swerving or braking
sharply. The indicator light . and indicator in
the d isplay will warn you about the danger
¢fig. 122. You will also hear an acoustic signal.
If you do not react fast enough or do not react at
a ll to the situation, Braking guard will intervene
by braking and the message
braking guard inter­
vention
will appear.
l) This is no t a vail able in som e coun trie s.
104
- If a collision is imminent , the system will first
provid e an
acute warning by briefly and sharply
app lying the b rakes.
- If you do not react to the acute warning, brak­
ing guard can brake within the limits of the sys ­
tem . This reduces the vehicle speed in the event
of a collision.
- At speeds under 20 mph (30 km/h), the system
can initiate a complete deceleration shortly be­
fore a collision ll.
- If the braking gua rd senses that you are not
braking hard enough when a collision is immi­
nent, it can increase the braking force.
Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the radio or MMI
¢page 105, Settings in the radio/MM!.
A WARNING
Lack of attent ion can cause collisions, other
accidents and ser ious personal injuries . The
braking guard is an assist system and cannot
prevent a collision by itself . The driver must
always inte rvene. The driver is always respon­
sible for braking at the correct time .
- Always pay close attention to traffic, even
when the braking guard is switched on. Be
ready to intervene and be ready to take
complete control whenever necessary. Al­
ways keep the safe and legal distance be­
tween your vehicle and vehicles up ahead .
- Braking guard works within limits and will
not respond outside the system limits, for
example when approach ing a stopped vehi­
cle or stationary obstacle (end of a traffic
jam or vehicle that has broken down in traf­
fic) .
- Always remember that the radar sensor for
the 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

(D Tips
- You can cancel the braking that is initiated
by the system by braking yourse lf, by accel ­
erating noticeably or by swerving.

Fig. 126 Rear of the veh icle: pos it ion of the sensors
Side assist functions at speeds above approxi­
mately 19 mph (30 km/h).
@ Vehicles that are approaching
In certain cases, a vehicle will be classified as
critical for a lane change even if it is still some­
what far away. The faster a veh icle approaches,
the sooner the display in the exterior mirror w il l
turn on.
@ Vehicles traveling with you
Vehicles traveling with you are indicated in the
exterior mirror if they are classified as critical for
a lane change. All vehicles detected by side assist
108
are indicated by the time they enter your "blind
spot", at the latest .
© Vehicles left behind
If you slow ly pass a vehicle that side assist has
de tected (the diffe rence 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 wi ll not turn on if you quickly pass a
vehicle that side assist has detected (the differ­ ence in speed between the vehicle and your vehi­
cle is greater than 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 certain situations, the dis­
play in the exterior mirror may turn on even
though there is no vehicle located in the area
that is crit ical 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 the vehicle in anoth­
er lane that is
not adjacent to your current lane.
- if you are driv ing 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 displaced guard rails) .
- In poor weather conditions. The side ass ist
functions are limited.
Do not cover the radar sensors
c:> fig. 126 with
stickers, deposits, bicycle wheels or other ob­
j ects, because this w ill affect the function . Do not
use side assist when towing a trailer. For infor­
mation on cleaning, refer to
c:> page 193.
A WARNING
- Always pay attention to traff ic 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
-
similar driving maneuvers . IJ>-
