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 exceeding 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 below the
stored maximum 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 include driving in a country
with a general speed limit or if there is a
specified maximum speed for winter tires .
@ Tips
Even though your vehicle is equipped with
a speed warning system, you should still
watch the speedometer to make sure you
are not driving faster than the speed limit.
Setting the threshold
You can set, change and delete the threshold
in the MMI.
"' Select: Systems or Car systems > Driver as
sist> Speed warning .
Driving 79
You can set any threshold between 20 mph (30 km/h) and 150 mph (240 km/h). Settings
can each be adjusted in increments of 6 mph
(10 km/h).
Cruise control system
Description
Applies to vehicles: with cruise control system
The cruise control system makes it possible to
drive at a constant speed starting at 15 mph
(20 km/h).
The speed is kept constant by modifying en
gine power or through an active brake inter
vention.
.&_ WARNING ~
- Always pay attention to the traffic
around you when the cruise control is in
operation. You are always responsible for
your speed and the distance between
your vehicle and other vehicles.
- For reasons of safety, cruise control
should not be used in the city, in stop
and-go traffic, on winding roads and
when road conditions are poor (such as ice, fog, gravel, heavy rain and hydro
planing) -you could have an accident.
- Switch the cruise control
off temporarily
when driving in turning lanes, highway
exits or in construction zones.
- Please note that unconsciously "resting"
your foot on the accelerator pedal pre
vents the cruise control from braking.
This is due to the control system being
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 switched
off. The other cruise control functions re
main active as long as the indicator light
II (US models) !l'I (Canadian models)

Audi adaptive cruise
control
Introduction
Ap plies to vehicles: with Audi adaptive cruise co ntrol
The adaptive cruise control system is a combi
nation of speed and distance regulation. It as
sists the driver by both regulating the speed
and maintaining a distance to the object
ahead, within the abilit ies of the system. If
the system detects an object, adaptive cruise
con trol can brake and accelerate your vehicle.
This together with the automatic transmis
sion* makes driving more comfortable both
on long stretches of highway and in stop-and
go traffic.
General Information
General information
A ppl ies to vehicles: with Audi adaptive cruise co ntrol a nd
Audi pre se nse fro nt
Fig. 70 Vehicle fro nt: sensor
The general information applies to adaptive
cruise control* and pre sense front*
c:>page90.
The radar sensor area c:>fig. 70 must not be
covered with stickers, deposits or any other
obstructions as it may impair the function of
the adaptive cru ise control and the pre sense
front. For information on cleaning, see
c:> page 201 . The same applies for any modifi
cations made in the front area .
The function of the adaptive cruise control
system and pre sense front is limited in some
conditions: -
Objects can only be detected when they are
within the sensor range
c:> page 84,
fig. 73.
-The system has a limited ability to detect
objects that are a short distance ahead, off
to the side of your vehicle or moving into
your lane.
- Objects that are difficult to detect such as
motorcycles, vehicles with high ground
clearance or an overhanging load are detect
ed late or not detected at all.
- When driving through curves
c:> page 83.
-With stationary objects r=;, page 83 .
A WARNING
-
Always pay attent ion to traffic when adap
tive cruise control is switc hed on and the
pre sense front is active
c:> page 90. As
the driver, you are still responsible for
start ing and for maint.;1 ining speed and
distance to other objects. The pre sense
front is used to assist you. The driver must
always take action to avoid a collision. The
driver is always responsible for braking at
the correct time.
- I mp roper use of adaptive cruise con trol
can cause collisions, other accidents and
serio us personal injury.
- Incorrect use of the adaptive cruise con
trol can cause collisions, other acc idents
and serio us personal injury.
- Incorrect use of the adaptive cruise con
trol can cause collisions, other accidents
and serio us personal injury.
- For safety reasons, do not use adaptive
cru ise control when driv ing on roads with
many curves, when the road surface is in
poor condition and/or in bad weather
(such as ice, fog, gravel, heavy ra in and
hydroplaning). Us ing the system under
these conditions could result in a colli
sion .
- Sw itch adaptive cruise contro l off tempo
ra rily when driving in turning lanes, on
expressway ex its or in construction
zones. This preven ts the vehicle from ac
celerating to the set speed when in these
situations .
Page 85 of 288

-The adaptive cr uise control system will
not brake by itself if you put your foot on
the accelerator pedal. Doing so can over
ride the speed and d istance regulation .
- When approaching stationary objects
such as stopped traffic, adaptive cruise
control will not respond and pre sense
front will have lim ited function.
- The adaptive cru ise control system and
pre sense front do not react to people,
animals, objects cross ing the road or on
coming objects.
- The function of the rada r senso rs can be
affected by reflective objects such as guard ra ils, the entra nce to a tunnel,
heavy rain or i ce.
- Never follow a veh icle so closely that you
cannot s top your vehi cle safe ly. The
adap tive cruise cont ro l c anno t slow or
brake the ve hicle safe ly when you follow
another vehicle too closely. Always re
member that the automatic braking
function 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 being used.
(D Note
The sensor can be disp laced by impacts or
damage to the bumper, whee l housing and
underbody. The adaptive cruise control
and pre sense front may become impaired
as a resu lt . Have your authorized Aud i
dea le r or q ual ified repa ir facility check
their function.

Fig. 73 Detect ion range
What can ad apti ve crui se contr ol do ?
The adaptive cruise contro l system uses radar
and a video camera. The radar is subject to
designated system limits¢
page 82.
On open roads with no traffic, it functions like
a cruise contro l system. The stored speed is
maintained. When approaching an object
ahead and the system detects it, the adapt ive
cru ise control system automatically brakes to
match that object's speed and then maintains
the stored d istance. As soon as the system
does not detect an object ahead, adaptive
cr uise contro l accelerates up to the stored
speed.
