Audi adaptive cruise control
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 90 Detection range
What can adaptive cruise control do?
The adaptive cruise control system uses video,
radar and ultrasou nd. Moving vehicles ahead
can be recognized up to about 650 feet (200 m) away.
On open roads w ith no traffic, 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 s lows down to match that vehi
cle's speed and then maintains the distance
that the driver previous ly 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, adapt ive cru ise control
can brake until the vehicle stops and acceler
ate again under certain conditions and if this
is possible within the system's limits and ca
pabilities¢
page 90. Adaptive cru ise 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" ¢
page 88, Switching on and off.
When driving, you can stop cruise control
¢
poge 90 or change the speed ¢ page 89
at any time.
You can also set the distance to the object
ahead and set the adaptive cruise control driv
ing program ¢

Audi adaptive cruise control and braking guard 91
When approaching a moving vehicl e up ahead,
the adaptive cruise contro l system automati
cally brakes to match that object's speed and
then maintains the stored distance.
If the ve
hicle 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) ¢.&. . The
Distance 3 setting
is recommended .
The distances prov ided are specified values .
Depending on the driving situation and the
how the vehicle ahead is driving, the actual
distance may be more or less than these tar
get distances.

A WARNING
Following other vehicles too closely in
creases the risk of collisions and serious
personal injur y.
- 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 .
(D Tips
-Distance 3 is set automatically each time
you switch the ignition on.

In certain situations, the system will prompt
you to take action . This could happen, for ex
amp le, if braking by the adaptive cruise con
trol system is not enough to maintain enough
distance to the vehicle ahead .

Audi braking guard
Descript ion
Applies to vehicles: with Audi adaptive cruise control
Fig. 97 Instrument cluster: approach warn ing
Braking guard uses radar sensors and a video
camera . It also functions within the limits of
the system when adapt ive 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 traveling at a
high speed and approaching a vehicle up
ahead that is moving more slowly . Brak ing
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
I in the display comes on .
- The
approach warning is given when a de
tected veh icle 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 possible to avoid a collision
by swerving or braking sharply. Th e indicator
light
I and indicato r in the display will warn
you about the danger¢
fig. 97. You will a lso
hear an acoustic signal.
ll This is not ava ilable in some co un tri es .
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 coll is ion is imminent, the system will
first provide an
acute warning by briefly and
sharply applying the brakes.
- If you do not react to the acute warning,
braking g uard can brake wit h increas ing
force w ith in the limits of the system . This
reduces the vehicle speed in the event of a
collision.
- The system can initiate maximum braking
short ly before a collision
1l . Full deceleration
at high speeds occurs only in vehicles with
adapt ive cruise control and side assist (pre
sense plus).
- If the braking guard senses that you are not
braking hard enough when a collision is im·
m inent, it can increase the braking force.
- The pre sense functions also engage when a
collision is imminent¢
page 194.
Which functions can be controlled?
You can switch braking guard and the dis
tance/approach warning on or off in the MMI
¢ page 93, 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 respons ible for braking at the cor
rect time.
- Always pay close att ent 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 ..,.

• 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 relevan t lane marker lines are not de-
tected (for example, markings in a construc
tion zone or because they are obstructed by
snow, dirt, water or backlight ing) .
- The vehicle 's speed is below the speed need
ed to activate it, which is about 40 mph (65
