82 Audi adaptive cruise control
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 .

94 Audi acti ve lan e assi st
Audi active lane assist
Lane assist
Description
App lies to vehicles: with Audi active lane assist
Active lane ass ist detects lane marker lines
within the limits of the system using a camera
in the windshield . If you are approaching a de­
tected lane marker line and it appears likely
that you wi ll leave the lane, the system will
warn you with corrective steering. You can
ove rride this steering at any time . If you pass
over a line, the steering wheel will vibrate lightly. In order for this warning vibration to
occur, it must first be switched on in the MMI.
Active lane ass ist is operable when the lane
marker line is detected on at least one side of
the vehicle .
The system will not warn you before cross ing
a lane marker Line if you have activated the
turn signal. In t his case, it assumes that you
a re changing lanes intent ionally.
The system is designed for driv ing on express ­
ways and h ighways and therefore only acti­
vates at speeds above app roximately 40 mp h
(65 km/h).
A WARNING
- The sys tem w arns the d river that the ve­
hicle is leaving the lane us ing corrective
steering . The driver is always responsible
for keeping the vehicle within the lane .
- The system can help you keep the vehicle
in the lane, but it does not drive by itself.
Always keep your hands on the steering
wheel.
- Co rrective stee ring may not occur in cer­
tain situations, such as d uring heavy
braking.
- There may be cases where the camera
does not recognize all lane marker lines.
Corrective steering can only take p lace
on the side of the veh icle where lane
marke r lines a re detected .
l) Thi s func tion is not available in a ll co untries.
- Other road structures or objects cou ld
possibly be identified un intent ionally as
lane marker lines. As a result, correct ive
steer ing may be unexpected or may not
occ ur.
- The camera view can be restricted, for
examp le by vehicles driving ahead or by
ra in, snow , heavy spray light shining into
the camera or by dirt on the window . T his
can result in act ive lane assist not detect­
ing the lane marke r lines or detec ting
them incorrect ly .
- I n certain sit uat ions where visibili ty is
low, the vehicle may swi tch from "early"
to "late" corrective steering
l).
-Unde r ce rtain condi tions such as ruts in
the road, an incl ined roadway or c ross­
winds, the corrective steering alone may not be enough to keep the vehicle in the
middle of the lane.
- For safety reasons, active lane assist
must not be used when the re a re poor
road and/or weather conditions such as
slippery roads, fog, grave l, heavy rain,
snow and the potential for hydroplaning .
Using act ive lane assist under these con­
d itions may increase the risk of a c rash .

Indicator lights
• Ready:
The indicator light turns on when
the system is ready for use. The system can
now be operated .
• Not Ready : The indica tor light turns on if
the system is switched on but is inoperable.
This may be due to the following reasons:
- There is no lane boundary line.
- The relevant lane marker lines are not de-
tected (for example, markings in a construc­
tion zone or because they are obstructed by
snow, dirt, water or light ing) .
- The vehicle speed is below the activation
speed of approximately 40 mph (65 km/h)
(the speed may vary depending on your
country) .
- The lane is narrower than 8
ft (2 .5 m) or
wider than 18
ft (5.5 m).
- The curve is too narrow.

-The driver's hands are not on the steering
wheel.
a) Tips
- Make sure the camera's field of view
~ fig. 82 is not obstructed by stickers or
other objects. For information on clean ­
ing, see¢
