A WARNING
Improper use of the adaptive cruise control
can cause collisions, other accidents and seri
ous personal injuries.
- Pressing the
ISETI button when driving at
speeds below 20 mph (30 km/h), will auto matically accelerate the ve hicle to 20 mph
(30 km/h), which is the minimum speed
that can be set.

Driving in stop -and-go traffic
Applies to: ve hicles w ith Audi adaptive cruise co ntro l
The adaptive cruise control system also assists
you in stop-and-go traffic.
If a previous detected
vehicle ahead stops, your vehicle will brake to a
stop, within the limits of the system.
• To resume driving with adaptive cruise control,

(Di Tips
-If adaptive cruise control is active and your
vehicle does not start driving as expected
after pulling the lever once, you can start
out again by tapping the accelerator pedal.
- If an obstacle is detected when your vehicle
starts driving, the system will prompt you
to take over<=>

drive more slowly when starting. This may
also happen in some situations when no ob
stacle is apparent.

Description
Applies to: vehicles w ith Aud i adapt ive c ru ise co ntro l
Fig. 106 Instrument cluster : approac h 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 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 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 avo id a coll is ion. 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 g iven, it may only be pos
sible to avo id a collision by swerving or braking
sharp ly. Th e indicator light. and indicator in
the display will warn you about the danger
qfig. 106. You will also hear an acoustic signal.
If you do not react fast enough or do not react at
all to t he situation, braking guard will intervene
by braking and the message
braking guard inter
vention
will appear.
l) Thi s is not available in some countries.
96
-If a collision is imminent, the system will first
provide an
acute warning by briefly and sharply
app ly ing the brakes.
- If you do not react to the acute warning, brak
ing guard can brake with increasing force with
in the limits of the system. This reduces the ve
hicle speed in the event of a collision.
- The system can initiate maximum braking
shortly before a co llision
1
) . Full deceleration at
high speeds occurs only in vehicles with adap
tive cruise control and side assist (pre sense
plus) .
- If the braking guard senses that you are not
braking hard enough when a collision is immi
nent, it can increase the braking force .
- The pre sense functions also engage when a
collision is imminent
qpage 187.
Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the MMI
¢ page 9 7, Settings in the MMI.
A WARNING
Lack of attention can cause collisions, other
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 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
comp lete control whenever necessary. Al
ways keep the safe and legal distance be
tween your vehicle and veh icles up ahead.
- Braking guard works within limits and will
not respond outside the system limits, for
example when approaching 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 brak ing guard works only within def ined ..,.
Audi adapt ive cruis e control and braking gua rd
de tect ion and range limits t hat may prevent
the proper detection of other veh icles.
- The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Moving veh icles up ahead may not be
promptly detected or may not be detected
at all .
- Reflective surfaces including crash barriers
or tunnel entrances may impair the funct ion
of the radar sensor.
(D Tips
- You can cancel the brak ing with increasing
force that is init iated by the system by b rak
i ng yourself, by accelerat ing noticeab ly or
by swerving .
- Braking guard error messages ¢
page 9 7.
- Keep in mind that braking guard can brake
unexpected ly. Always secure any cargo or
objects that you are transport ing to reduce
the risk of damage or injury .
