82 Audi ad apti ve cruise contr ol a nd bra king gu ard
vehicles or obstacles that are not moving
can trigger a collision warning and if con­
firmed by the v ideo camera, an acute col­
lis ion warn ing .
- For safety reasons, do not use adaptive
cruise co ntrol when driving 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) . Using the system under
these cond it ions cou ld result in a co lli ­
sion .
- Swi tch adap tive c ruise control off tempo­
rar ily when driv ing in turning lanes, on
expressway exits or in construction
zones. This prevents the vehicle from ac­
celerat ing to the set speed when in these
situations.
- The adapt ive cruise control system wi ll
not brake by itse lf if you put 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
co ntrol will not respond and braking
guard w ill have limited function.
- The adapt ive cruise control system and
braking guard do not react to people, an­
imals, objects c rossing the road or on­
coming objects .
- The function of the radar senso rs can be
affected by reflective objects such as
guard rai ls , the entrance to a tunnel,
heavy rain or ice.
- Never follow a ve hicle so closely that you
cannot stop your vehicle safe ly. The
adaptive cruise contro l canno t slow or
brake the vehicle safely when you follow
another vehicle too closely. Always re­
member that the automatic braking
function cannot br ing 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 sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. That cou ld affect the adaptive
cruise control system and brak ing guard.
Have your authorized Aud i dea ler or au ­
thorized Audi Service Facility check their
funct ion .

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)

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.

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

Audi adaptive cruise control and braking guard 87
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 96 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
I 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 possible to avoid a collision
by swerving or braking sharply. The indicator
l ight
I and indicator in the display will warn
you about the danger
c::> fig . 96. You will a lso
hear an acoustic signal.
11 This is not ava ilable in som e coun 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.
- I f a collision 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 with increasing
force within the limits of the system . This
reduces the vehicle speed in the event of a
collision.
- 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 187 .
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 191.
- 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.

104 Automatic Transmission
Automatic
Transmission
tiptronic
Introduction
The automatic transmission is controlled elec­
tronically. The transmission upshifts or down­
shifts automatically depending on which drive program is selected.
When a
moderate driving style is used, the
transmission selects the most economical driving mode. It will then change up early and
delay the downshifts to give better fuel econ­
omy.
The transmission switches to a sporty mode
after a k ick-down or when the driver uses a
sporty driving style characterized by quick ac­
celerator pedal movements, heavy accelera­
tion, frequent changes in speed and traveling
at the maximum speed.
If desired, the driver can also select the gears
manually (tiptronic mode ) ¢ page 108.
In the tiptronic transmission, power is trans­
ferred by a torque converter.
Selector lever positions
