Speed warning system
Description
Applies to: veh icles with speed warning system
The speed warning system helps you to stay be­
low a specified maximum speed that can be set,
changed or deleted in the Infotainment system.
The speed warning system warns you if you are
exceeding the maximum speed that you have set .
A warni ng tone will sound as soon as your speed
exceeds the sto red value slight ly. The
[OJ (USA
models) ;[;] (Canada models) indica to r li gh t and
the co rresponding message appear in the inst ru­
ment cluster display at the same time. The
[C]
(USA models)/ [ej (Canada mode ls) indicator
light and the message turn off w hen the vehicle
speed drops below the stored maximum speed .
Sett ing a threshold is recommended if you would
like to be reminded when yo u reach a certa in
maximum speed . Situations where you may want
to do so include driving in a country with a ge ner­
al speed limit or if there is a specified maximum
speed for winter tires.

&_ WARNING
- Always pay at ten tion to the traffic a ro und
you whe n the cruise contro l system is in op­
erat ion . You are always respons ible fo r your
speed and the distance between your vehi­
cle and other vehicles.
-For safety reaso ns, cruise cont rol should not
be used in the city, in stop-and-go traff ic, on
w inding roads and when road conditions are
poor (such as ice, fog, gravel, heavy rai n and
hydroplaning), because this increases the
r isk of an accident.
-Switch t he cr uise control off temporarily
when dr iv ing in turning lanes, highway exits
or in construction zones .
- Please note that unconsciously
"rest ing"
your foot on the accelerator pedal prevents
-

Ass is tanc e system s
-your vehicle is traveling at speeds between ap ­
proximately 20 to 50 mph (30 to 85 km/h) and
it approaches a stationary vehicle.
- your vehicle is traveling at speeds between ap ­
proximately 20 to 155 mph (30 to 250 km/h)
and it approaches a vehicle that is clearly trav ­
eling more slowly or a veh icle in your direction
o f travel tha t is stopped.
When this warning occurs, it may only be possi ­
b le to avoid a collision by swerving or braking
strong ly. The message
A udi pre sense.
¢ fig. 134 and a warning tone will warn you
about the danger .
If there is an impending collision with vehicles,
there will a lso be an
acute warning in the form of
sharp braking. If you do not react to the acute
warn ing, pre sense front can brake with increas ­
ing force within the limits of the system . T his re­
duces the vehicle speed in the event of a coll i­
sion .
Autom atic deceleration
Depending on the speed, pre sense front can de­
cel erate automatica lly
shortly before a collision:
-if there are stationary vehicles when you are
traveling at speeds up to approx imately 28
mph (45 km/h)
-if there are veh icles dr iv ing or stopped ahead
whe n you are traveling at speeds up to approxi­
mately 155 mph (250 km/h)
Autom atic bra king force inc rea se
If pre sense front determines that you are not
braking strongly enough when a co llision is imm i­
nent, it can inc rease the braking force, depending
on the situation and speed:
-if there are stationary vehicles when you are
traveling at speeds up to approx imately 50
mph (85 km/h)
-if the re are ve hicles driving or stopped ahead
when you are traveling at speeds up to approxi­
mately 155 mph (250 km/h)
A WARNING
Pre sense front cannot ove rcome the laws of
physics . It i s a system des igned to assist and
132
it cannot prevent a coll is io n in eve ry ci rc u m ­
stance . The driver m ust always intervene. The
driver is always respons ible for braking at the
correct time . Do not let the inc reased safety
provided tempt yo u into tak ing risks . This
could inc rease your r isk of a co llision.
-Keep in mind that pre sense front can pro­
vide war nings or b rake unexpectedly. Al­
ways secure a ny cargo or objects that yo u
a re transporting to reduce t he ris k of dam­
a ge or inj ury.
-The system can dep loy in co rre ctly due to
sys tem -specific li mits.
-Please note that the se nsor does not a lways
detect a ll obje cts. Thi s increases the r is k of
a c ollision .
-Pre sense front does not rea ct to ve hicles
tr ave ling towa rd yo u in the same lane, to
peop le, groups of people, anim als, ob je cts
that are crossing the road, or objects t hat
are difficult to
detect ¢.& in General infor­
mation on page 124 .
A WARNING
Pre sense front may be restricted o r not avai l­
ab le in the fo llow ing example s ituations :
-if there a re othe r reflective objects nearby,
such as gua rd ra ils or vehicles
-when driving into a tunnel
-in heavy fog, ra in, sp ray o r snow
-if the rada r senso r is d irty, covered in ice,
d amaged, or cove red
- in curves
- if the ESC was restr icted or sw itched off
@ Note
The sensor can be d isplaced by impacts or
damage to the bumper, wheel housing and underbody. Pre sense front can be impaired
by this . Have an author ized A udi dealer or au­
