Speed warning system
Introduction
The speed warning system helps you to stay
under a specified maximum speed.
The speed warning system warns you if you
are exce edin g the maximum speed that you
have set. You will hear a warning tone when
your speed exceeds the stored value by ap
proximately 3 mph (3 km/h). An indicator
light. (USA models)/ . (Canada models) in
the instrument cluster display also turns on at
the same time. The indicator light./.
turns off when the speed decreases be low the
stored maxim um speed.
Setting a threshold is recommended if you
would like to be reminded when you reach a
certain maximum speed. Situations where you
may want to do so incl ude driving in a co untry
with a general speed limit or if there is a
specified maximum speed for winter tires.
@ Tips
Even though your vehicle is equipp ed w ith
a speed warning system, you sho uld still
watch the speedometer to make sure you
are not driv ing faster than the speed limit.
Setting the threshold
You can set, change and delete the threshold
in the MMI.

A WARNING
--Always pay attent ion to traffic even when
the cruise control is switched on. You are always responsible for your speed and
the distance between your vehicle and
other vehicles.
- For safety reasons, the cruise contro l
should not be used in the city, in stop
and-go traffic, on twisting roads and
when road conditions are poor (such as
ice, fog, gravel, heavy rain and hydro
p lan ing) -risk of accident .
- Turn off the cruise control temporarily
when entering turn lanes, highway exit
lanes or in constr uction zones .
- Please note that inadve rtently "resting"
your foot on the accelerator pedal causes the cruise control not to brake. This is
because the cruise control is overridden
by the driver's acceleration.
- If a brake system malfunction such as
overheating occurs when the cruise con
trol system is switched on, the braking
function in the system may be sw itched
off. The other cruise control functions re
main active as long as the indicator light
II (US models)/ ... (Canadian models)

Audi adaptive cruise
control and braking
guard
Introduction
App lies to vehicles: with Audi adaptive cruise co ntrol
The adaptive cruise control system assists the
driver by regu lat ing vehicle speed and helping
to maintain a set distance to the vehicle
ahead, within the limits of the system.
If the
system detects a moving vehicle up ahead,
adaptive cruise control can brake and then ac
celerate your vehicle. This helps to make driv
ing more comfortable both on long highway
stretches and in stop-and-go traffic.
The braking guard system can warn you about
an impending collision and initiate braking
maneuvers
c:::> page 92.
Adaptive cruise control and braking guard
have technical limitations that you must
know, so please read this section carefully, un
derstand how the system works and use them
properly at all times.
General information
General information
Applies to vehicles: with Audi adaptive cruise control
Fig. 89 Front of th e veh icle: senso rs and video camera
The areas that conta in the radar and ultrason
ic sensors and the v ideo camera
c:::> fig. 89
must neve r be cove red by stic kers or other ob
jects or obstructed w ith dirt, insects, snow or
i ce that will interfere with the adaptive cruise
control system and braking guard. For infor
mation on cleaning, refer to
c:::> page 212. The same applies for any modifications made in
the front area.
T he function of the adaptive cru ise contro l
system and braking guard is limited under
some cond itions:
- Objects can only be de tected when they are
w ith in sensor range
c:::>page 88, fig. 92.
- The system has a limited ability to detect
objects that are a short d istance ahead, off
to the side of your vehi cle or mov ing into
your lane.
- Some kinds of ve hicles are hard to detect;
for examp le motorcycles, veh icles with high
ground clearance or overhanging loads may
be detected when it is too late or they may
not be detected at all.
-When driving through curves
c!,>page 87 .
-Stat ionary objec ts c:::> page 87.
& WARNING
A lways pay attention to traffic when adap
tive cruise contro l is switched on and brak
ing g uard is active. As the dr iver, you are
still respons ible for starting and for main
taining speed and distance to other ob
jects. Braking guard is used to assist you .
The dr iver must a lways take action to avo id
a collis ion . The driver is a lways respons ible
fo r braking a t the co rrec t time.
- Imp roper use of adaptive cru ise control
can cause collisions, other acc idents and
serious pe rsonal in jury.
- Never let the comfort and convenience
that adaptive cruise control and braking gua rd offer d istract you from the need to
be alert to traffic condit ions and the
need to rema in in fu ll control of your ve
h icle at a ll times,
- Always remember that the adaptive
cruise control and braking guard have
limits -they will not s low the vehicle
down or maintain the set distance when
you drive towards an obstacle or some
thing on or near the road that is not
mov ing, such as vehicles stopped in a
traffic jam, a stalled o r disabled vehicle.

vehicles or obstacles that are not moving
can trigger a collision warning and if con
firmed by the video camera, an acute col lis ion warn ing.
- For safety reasons, do not use adaptive
cruise control 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 itions cou ld result in a co lli
sion .
- Switch adaptive 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
celerating to the set speed when in these
situations .
- The adapt ive cru ise control system w ill
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 traffic, adaptive cruise
control 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
ima ls, objects crossing the road o r on
coming objects .
- The function of the radar sensors can be
affected by reflective objects such as
guard ra ils, the entra nce to a tunnel,
he avy rain or i ce.
- Never follow a veh icle so closely that you
cannot stop your vehicle safe ly. The
adaptive cruise cont ro l c anno t slow or
brake the veh icle safely when you follow
another vehicle too closely. Always re
member that the automatic braking
funct ion cannot bring the veh icle to a
sudden or emergency stop under these
condit ions .
- To prevent unintended operation, always
switch ACC off when it is not be ing 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 le r or a u
