2014 AUDI A5 CABRIOLET cruise control

94 Audi adaptive cruise control and braking guard
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
hydroplaning). Using the system under
these conditions could result in a colli­
sion.
- Switch adaptive cruise control off tempo­
rarily when driving in turning lanes, on
expressway exits or in construction
zones. This prevents the vehicle from ac­
celerating to the set speed when in these
situations.
- The adaptive cruise control system will
not brake by itself 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 traffic, adaptive cruise
control will not respond and braking
guard will have limited function.
- The adaptive cruise control system and
braking guard do not react to people, an­
imals, 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 vehicle so closely that you cannot stop your vehicle safely. The
adaptive cruise control cannot slow or
brake the vehicle safely when you follow
another vehicle too closely . Always re­
member that the automatic braking
function cannot bring the vehicle to a sudden or emergency stop under these
conditions.
- To prevent unintended operation, always
switch ACC off when it is not being used.
{[) Note
The sensor can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. That could affect the adaptive cruise control system and braking guard.
Have your authorized Audi dealer or au­
thorized Audi Service Facility check their
function.

Fig. 104 Example: driv ing into a curve
When driving into a curve <=> fig. 104 and out
of a curve, the adaptive cruise control may re­ act 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
Applies to vehicles: with Aud i adaptive crui se contro l
Fig. 105 Example: object changing lanes a nd station ­
a ry object
The adaptive cruise control system only reacts
to objects that are moving or that the system
has already detected as moving. For example,
if a vehicle @, which has already been detect­
ed by the adaptive cruise control, turns or
changes lanes and another stationary vehicle
@ is located in front of that vehicle, the sys­
tem will not react to the stationary vehicle.

What can Audi adaptive cruise control do?
The adaptive cruise control works in conjunc­
tion with a radar sensor installed in the front
of the vehicle ¢
page 93, fig . 103, which is
subject to designated sys tem limits
¢
page 95. Stationary objects are disregard­
ed .
On open roads w ith no traffic, adaptive cruise
control wo rks 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.
Which functions can be controlled?
When you switch adaptive cruise control on,
you can set the current speed as the "control speed" ¢
page 95, Switching on and off.
When driving, you can stop cruise control
¢
page 97 or change the speed¢ page 96
at any time .
You can a lso set the distance to the object
ahead and set the adaptive cruise control driv­ ing program
¢ page 97.

-If you switch the ignit ion or the adaptive
cruise control off, the set speed is erased
from the system memo ry.
- The electronic stab ilizat ion control (ESC)
and the anti-slip-regulat ion (ASR) are au­

Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 113 Instrument cluste r: approac h warn ing
Braking guard uses a radar sensor. It also
functions within the limits of the system
when adaptive cruise control is switched off.
What can Audi 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 . Braking
gua rd 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 wi ll
not be able to avoid a collis ion. 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 much more slowly than you are or if it
brakes sharply . When th is warning is given,
it may only be possible to avoid a collision
by swerving or braking sharply. Th e indicator
light. and indicator in the display will
warn you about the danger
c::> fig. 113. You
will a lso hear an acoustic signa l.
If you do not react fast enough or do not react
at all to the situation, Braking guard will in-
ll This is not ava ilable in som e coun tri es.
tervene by braking and the message braking
guard intervention will appear.
- If a coll ision 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 guard can brake within the lim its of
the system. This reduces the vehicle speed
in the event of a collision.
- At speeds unde r 20 mph (30 km/h), the sys­
tem can initiate a comp lete deceleration
shortly before a collision
ll.
- If the braking guard senses that you are not
braking hard enough when a collision is im­
minent, it can increase the braking force .
Which functions can be controlled?
You can switch braking guard and the dis­
tance/approach warning on or off in the radio
or M MI
c::> page 100, Settings in the radio/
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 dr iver is
always respons ible for braking at the cor­
r ect time .
- Always pay close attention 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 examp le when approaching a
stopped vehicle or stationary obstacle (end of a traffic jam or vehicle that has
broken down in traffic).

- Always remember t hat t he radar sens or
fo r the braking guard wo rks only within
defined detection and range limits that
may preve nt the proper detection of oth­
er v eh icles.
- The radar senso r's fu nction and range
can be reduced by rain, s now a nd heavy
spray. Mo ving v ehicl es u p ahead may not
