Audi adaptive cruise
control
Description
Applies to vehicles: with Audi adaptive cruise co ntrol
Fig. 91 Detectio n range
What can adaptive cruise control do?
The adaptive cruise control system uses video,
radar and ultrasound . Moving vehicles ahead
can be recognized up to about 650 feet (200 m) away.
On open roads w ith no traff ic, adaptive cruise
control works like a regular cruise control sys­
tem. The stored speed is maintained . When
approaching a moving vehicle detected up
ahead, the adaptive cruise control system au­
tomatically slows down to match that vehi­
cle's speed and then maintains the distance
that the driver previously stored. As soon as
the system does not detect a vehicle up
ahead, adaptive cruise control accelerates
back up to the stored speed.
In stop-and-go traffic, adaptive cruise control
can brake until the vehicle stops and acce ler­
ate again under certain conditions and if this
is possible within the system 's limits and ca­
pabilities
c> page 85. Adaptive cruise control
will not make an emergency stop .
Which functions can be controlled?
When you switch adaptive cruise contro l on,
you can set the current speed as the "control speed"
c> page 83, Switching on and off.
When driving, you can stop cruise control
c> page 85 or change the speed c> page 84
at any time.
You can also set the distance to the object
ahead and set the adaptive cruise control driv­
ing program

_&. WARNING
Improper use of the adaptive cruise con­
trol can cause collisions, other accidents
and serious personal injur ies.
- Pressing the
ISET ! button when driv ing at
speeds be low 20 mph (30 km/h), will au­
tomatically accelerate the vehicle to 20
mph (30 km/h), which is the minimum
speed that can be set.
© Tips
-If you switch the ignit ion or the adaptive
cruise control off, the set speed is erased
from the system memory.
- Th e electronic stabilizat ion contro l (ESC)

86 Audi adaptive cruise control and braking guard
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. If the ve­
h icle ahead accelerates, adaptive cruise con­
trol will also accelerate up to the stored
speed.
The higher the speed , the greater the distance
in yards (meters)
c::> & . The Distance 3 setting
is recommended .
The distances prov ided are spec ified values .
Depending on the driving situation and the
how the vehicle ahead is driving, the actual
d istance may be more or less than these tar ­
get distances.
The various symbols for the time increments
appear briefly in the information line @
c::> page 83, fig . 93 when you change the set ­
tings .
~-~- --Distance 1 : This setting corre­
sponds to a distance of 92 feet/28 meters
when traveling at 62 mph (100 km/h), or a
time interval of 1 second.
~--~- -Distance 2: This setting corre­
sponds to a distance of 118 feet/36 meters
when traveling at 62 mph (100 km/h), or a
time inte rval of 1.3 seconds .

sponds to a distance of 164 feet/SO meters

sponds to a distance of 210 feet/64 meters
when traveling at 62 mph (100 km/h), or a
time interval of 2.3 seconds .
A WARNING ,. -
Following other vehicles too closely in­
creases the risk of collisions and serious
personal inj ury.
- Setting 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 attention to traffic. -
Always obey applicable traffic laws, use
good judgment, and select a safe follow­ ing d istance for the traff ic, road and
weather conditions.
@ Tips
- Distance 3 is set automatically each time
you switch the ignition on.
- Your standard settings are automatically
stored and assigned to the remote con­
trol key being used.

Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 98 Instrument cluster: approach warning
Braking guard uses radar sensors and a video
camera . It also functions within the limits of
the system when adaptive cruise control is
switched off .
What can braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes sud­
denly or if your own vehicle is t raveling at a
high speed and approaching a vehicle up
ahead that is moving more slowly . Braking
guard does not react if it cannot detect the
situation.
The system advises you of various 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 de­
tected vehicle up ahead in your lane is mov ­
i ng much more slowly than you are or if it
brakes sharply . When this warning is given,
it may only be possib le to avoid a collision
by swerving or braking sharply. The indicator
light. and indicator in the display will
warn you about the danger
c::> fig. 98. You
will also hear an acoustic signa l.
"' rl
"' 11
This is not ava ilable in som e coun tri es. rl
If you do not react fast enough or do not react
at all to the situation, braking guard will inter­
vene by braking.
- If a col lision is imminent, the system will
first provide an
acute warning by brief ly and
sharply applying the brakes.
- If you do not react to the acute warning,
braking g uard can brake with increasing
force within the limits of the system . This
reduces the vehicle speed in the event of a
co llision.
- The system can initiate maximum braking
shortly before a collision
1 ) . Full deceleration
at high speeds occurs only in vehicles with
adaptive cru ise control and side assist (pre
sense plus) .
- If the braking guard senses that you are not
braking hard enough when a collision is im­
minent, it can increase the brak ing force .
- The pre sense functions also engage when a
collision is imm inent
c::> page 184 .
Which function s can be controlled?
You can switch braking guard and the dis­
tance/approach warning on or off in the MMI
c::> page 88, Settings in the MMI.
A WARNING
Lack of attention can cause collisions, oth­
er accidents and serious personal injuries .
The braking guard is an assist system and
cannot prevent a collision by itself. The
driver must always intervene. The driver is
always responsible for braking at the cor­
rect time.
- Always pay close attent ion to traffic,
even when the braking guard is switched
on. Be ready to intervene and be ready to
take comp lete control whenever necessa­
ry . Always keep the safe and legal dis­
tance between your vehicle and vehicles up ahead .
- Braking guard works within limits and
will not respond outside the system lim­ its, for example when approaching a

88 Audi adaptive cruise control and braking guard
stopped vehicle or stationary obstacle (end of a traffic jam or vehicle that has
broken down in traffic).
- 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 oth­
er 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 all.
- Reflective surfaces including crash barri­
ers or tunnel entrances may impair the
function of the radar sensor.
({) Tips
-You can cancel the braking with increas­
ing force that is initiated by the system
by braking yourself, by accelerating no­
ticeably or by swerving.
- Braking guard error messages
¢page 88.
- Keep in mind that braking guard can
brake unexpectedly . Always secure any
cargo or objects that you are transport­
ing to reduce the risk of damage or in­
jury.

(D Tips
- Your settings are automatically stored
and assigned to the remote control key being used at the time the settings are
made.
- If you restrict or switch off the ESC, the
braking guard also switches itself off
¢page 189.
- Switch braking guard off when you are
loading the vehicle onto a vehicle carrier,
train, ship or other type of transporta­
tion. This can prevent undesired warn­
ings from the braking guard system.

• Not ready: The indicator light shows that
the system is turned on but unable to send a
warning. This can be due to the following:
- There is no lane marker line.
- The relevant lane marker lines are not de-
tected (for example, markings in a construc­
t ion zone or because they are obstructed by
snow, dirt, water or backlighting).
- The veh icle 's speed is below the speed need ­
ed to activate it , which is about 40 mph (65

- The lane is narrower than about 8
