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.
Setting the warning thr eshold

@ Tips
Regardless of the speed warning system, you
should always monitor yo ur speed using the

-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

General information
Applies to: vehicles with Audi adaptive cruise contro l/Audi pre
sense front
Fig . 1 23 Front o f veh icle: sensor
The rada r sensor area r:!) fig. 123 must not be cov­
ered with stickers, deposits or any other obstruc­
tions as it may impair the function of the adap ­
tive cruise control or the pre sense front . For in­
formation on cleaning,
see ¢ page 354 . The
same applies for any modifications made in the
front area .
The funct ion of the adaptive cruise contro l sys­
tem or pre sense front is limited in some condi ­
tions:
-Vehicles can only be detected when they are
within the sensor range
¢page 123, fig. 122 .
-The system has a lim ited abi lity to detect
vehicles that are a short d istance ahead , off to
the side of your vehicle or moving into your lane .
-Objects that are difficu lt to detect such as mo­
torcycles, vehicles with h igh ground clearance
or an overhang ing load are detected late or not
detected at all.
-When dr iving through curves ¢ page 125.
-When the vehicle is stationary ¢ page 125.
A WARNING
Always pay attent io n to the traffic aro und you
when adaptive cruise control is switched on .
As the driver, you a re st ill respons ible for your
own speed and the distance to othe r vehicles.
Th e adapt ive cr uise control is u sed to assis t
you . The driver must a lways take act ion to
avoid a collision . The driver is always responsi ­
ble for brak ing at the correct time .
124
-For safety reasons, do not use adaptive
cru ise control when dr iving 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 hydroplan­
ing). Using the system under these cond i­
tions could result in a co llision .
-Switch adaptive cruise cont rol off tempora­
rily when dr iv ing in turning lanes, on ex­
pressway ex its or in construction zones. This
prevents the veh icle from accelerating to
the stored speed when in these situat io ns.
-The adap tive cruise contro l system will not
brake by itself if you put yo ur foot on the ac­
celerator pedal. Doing so c an override the
speed and distance regulation .
- Adapt ive cruise control does not respond to
peop le, animals, or crossing or oncoming
objects .
-The funct ion of the radar se nsors can be af­
fected by ref lective objects such as guard
rails, the entrance to a tunnel, heavy rain or
ice .
~ Note
The sensor can be d isplaced by impacts or
damage to the bumper, wheel housing and underbody . This can impair the adaptive
cruise control. Have an authorized A udi dealer
or authorized Audi Service Facility check their
f u nct ion.
@ Tips
For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regu lations, see

Ill-Adaptive cruise control is switched on . No
veh icles are detected ahead . The stored speed is
maintained.
• -A vehicle driving ahead was detected. The
adapt ive cruise control system regulates the
speed and d istance to the vehicle ahead and
brakes/accelerates automatically.
(-) -Adaptive cruise control is switched on. Ave­
h icle was detected ahead . Yo ur vehicle remains
stopped and w ill not start driv ing automat ica lly .
• -The automatic braking is not enough to
maintain a sufficient distance to a vehicle dr iv ing
ahead . You must intervene

If adaptive cruise contro l is not shown in the in­
strument cluster display, you can call i t up using
the multifunction steering wheel buttons
r:::;, page 13 .
Based on the graphics in the d isp lay, you can de­
termine if the system is mainta ining a distance to
a vehicle ahead and what that distance to this ve­
h icle is:
No vehicle -no vehicle was detected driving
ahead.
Sil ver vehicle -a vehicle was detected driving
ahead.

The five distance bar s on the gauge@ represent
the set d istance (refer
to r:::;, page 128 for infor­
mat io n on how to change the distance). If yo u
fa ll below the se lected distance, the distance
bars become red from the bottom upward.
A WARNING
If you press the ISE TI b utton when driving at
speeds below 20 mph (30 km/h), the vehicle
accelerates automat ica lly up to 20 mph (30
km/h), which is the m inimum speed that can
be set.

@ Tips
- If you switch the ignition or the adaptive
cruise control system off, the set speed is
erased for safety reasons.
- The electronic stabilization control (ESC)
and the anti-slip-regulation (ASR) are auto­
matically switc hed on when the adaptive
cruise control is switched on.

Fig. 131 Oper ating lever: setting the distance
• Tap the switch to display the current set dis­
tance
¢fig. 131.
• T o increase or reduce the distance in incre ­
ments, tap the switch upward/downward
again. The d istance between the two vehicles
will change in the instr ument cluster disp lay.
When approaching a veh icle driving ahead, the
adaptive cru ise control system brakes to match
that vehicle's speed and then adjusts to the set
d istance.
If the vehicle dr iv ing ahead accelerates ,
then the adaptive cruise control will also acceler­
ate up to the speed that you have set.
The higher the speed, the greate r the d istance
c::;, ,&. . The Di stan ce 3 setting is recommended.
128
That is equa l to the general recommendation of
"ha lf the speed shown on the spe edometer".
The distances provided a re spec ified values . De­
pending on the dr iv ing situation and how the
ve­
hicle ahead is driving, the actual distance may be
more or less than these target distances .
If you c hange the time gaps, the newly set va lue
appears b rief ly in the instrument cl uster d isplay,
for example
