ed maximum speed.
Setting a thresho ld is recommended if yo u
wo uld like to be reminded when you reach a
certain maximum speed . Situations where you
may want to do so include d riving in a country
with a general speed limit or if there is a
specified max imum speed for winter tires.
@ Tips
Regard less of the speed warning system,
you shou ld always mon itor your speed us­
ing the speedometer and make sure you
are following the legal speed limit.
Setting the threshold

(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
Appl ies to vehicles : with cruise con trol system
The c ruise control system makes i t possible to
d rive at a constant speed starting at lS mph
(20 km/h).
The speed is kept constant by modify ing en­
g ine power or through an a ct ive brake in ter ­
vention.
A 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 contro l
should not be used in the c ity, in stop-
Dri vin g 85
and-go traffic, on winding roads and
when road cond itions are poor (such as
ice, fog, gravel, heavy rain and hydro­
plan ing) -you could have an accident.
- Switch the cruise control off temporarily
when dr iv ing in turning lanes, h ighway
e xits or in construction zones.
- Please note that unconsc iously "resting"
your foot on the accelerator pedal p re­
vents t he cr uise control from b raking.
This is due to the control system be ing
over ridden by the dr iver's acceleration .
- If the re is a brake system malfunct ion
such as overheating when the spee d
warn ing system is switched on, the bra k­
ing f unction in the system w il l be deac ti­
vated . The remaining speed warning sys ­
tem fu nctions will remain active, as long
as the
Ill ( U SA mode ls) I l'I (Canada
models) indicator light is on.
(D Tips
- T he cr uise control system is ideal fo r
st retches wit h speed limits. The driver is
responsib le for adhering to the correct
speed.
- The cr uise control remains act ive when
shift ing gears.
- The b ra ke lights turn on when the b rakes
are act ivated.

Audi adaptive cruise control
Introduction
App lies to vehicles: with Audi adaptive cruise control
The adaptive cruise control system is a com bi·
nation of speed and distance regulation. It as ­
sists the dr iver by both regulat ing the speed
and maintain ing a distance to the object
ahead, within the abilities of the system. If
the system detects an object, adaptive cru ise
control can brake and acce le rate your ve hicle.
This makes driving more comfortable both on l ong stretches of highway and in stop-and -go
traffic.

c::> page 204. The same applies for any modifi­
cations made in the front area.
The function of the adaptive c ruise control
system and pre sense front is lim ited in some
conditions :
Audi ad apti ve crui se control 8 7
- Objects can only be detected when they are
within the sensor range
c::> page 88,
fig. 87 .
-The system has a limited ability to detect
objects that are a short d istance ahead, off
to the side of your vehicle or moving into
your lane.
- Objects that are difficult to detect such as
motorcycles, veh icles with high ground
clearance or an overhanging load are detect­
ed late or not detected at all.
- When driving through curves
c::>page 88.
-With stationary objects c::> page 88 .
A WARNING
Always pay attent ion to traffic when adap­
tive cruise control is switched on and the
pre sense front is active
c::> page 95. As
the driver, you are s till respons ib le for
start ing and fo r ma inta in ing speed and
d is ta nce to o ther objec ts. The pre sense
front i s used to ass ist yo u. The dr iver must
al ways take ac tion to avo id a col lision . The
driver is always responsible for braking at
the correct time .
- I ncorrect use of the a daptive cr uise con ­
trol can cause collisions, ot her accidents
an d serio us pe rsonal inj ury .
- For safety reasons, do not use adaptive
cru ise contro l when driv ing o n roads with
many curves, when the road s urface is in
poor condition and/or in bad weather
(such as ice, fog, grave l, heavy ra in and
hydroplaning). Using the system unde r
these co ndit ions co uld res ult in a coll i­
sion.
- Sw itch adaptive cru ise cont ro l off tempo·
ra rily whe n driving in tu rni ng lanes, o n
expressway ex its or in construction
zones. T his preven ts the vehicle from ac ­
celerating to the se t speed when in t hese
situations .
- Th e adap tive cruise control system
will
not brake by i tsel f if you pu t your foo t on
the accelera to r pedal. Do ing so can ove r-
ride t he speed and distance reg ulat io n.

88 Audi adaptive cruise control
- When approaching stationary objects
such as stopped traff ic, adaptive cruise
control will not respond and pre sense
front will have limited function.
- The adaptive cruise 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 radar sensors can be
affected by reflective objects such as
guard rai ls, the entrance to a tunnel,
heavy rain or ice.
- Never follow a veh icle so closely that you
cannot stop your vehicle safe ly. The
adaptive cruise control cannot slow or
brake the vehicle safely when you follow
another vehicle too closely. Always re­
member that the automatic braking
function ca nnot 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 sensor can be disp laced by impacts o r
damage to the bumper, whee l housing and
underbody . The adaptive cruise contro l
and pre sense front may become impaired
as a result . Have an authorized Audi dealer
or author ized Audi Service Facility check
their function.
In curves
Applies to vehicles: with Audi adaptive cruise control and
Audi pre sense fro nt
Fig. 85 Examp le: driv ing into a curve
When driving into a curve c::> fig. 85 and out of
a curve, the adaptive cruise control may react
to an object in the neighboring lane and apply
the brakes. You can prevent that by pressing
the accelerator pedal briefly .
Stationary objects
Applies to vehicles: with Audi adaptive cruise contro l and
Audi pre sense front
Fig. 86 Example: object chang ing lanes a nd stationary
object
Adaptive crui se control
The adaptive cruis e control system only reacts
to objects that are moving or that the system has a lready detected as moving. For examp le,
if a detected vehicle @tur ns or changes
lanes, the adaptive cruise control will not re­
act to a stopped vehicle @. Press the brake
pedal to slow your vehicle down .
Pre sense front
Pre sense front only reacts to stationary ob­
jects at low speeds.

What can adaptive cruise control do?
The adaptive cruise control system uses rada r
and a video camera. The radar is subject to
designated system limits ¢ page 87.
On open roads w ith no traffic, it functions l ike
a cruise control system . Th e stored speed is
maintained . When approaching an object
ahead and the system detects it, the adaptive
cr uise control system automatically brakes to
match that object's speed and then maintains
the stored distance. As soon as the system
does not detect an object ahead, adaptive
cru ise control accelerates up to the stored
speed .
With in the limits of the system, adaptive
cru ise control can brake in stop-and-go traff ic
until the vehicle is stationary and then begin
driving aga in under certa in conditions
¢ page 91, Driving in stop-and-go traffic.
Which functions can be controlled?
When you switch adaptive cruise control on,
you can set the current speed as the "control speed" ¢ page
89, Switching on/off.
When driving, you can stop cruise control
c::> page 91 or change the speed c::> page 90
at any time .
You can also adjust the following settings:
