@ Tips
- The light sensor* for headlight control is
located in the rear view m irror mount.
You should therefore not apply any st ick­
ers to the windsh ield in this area in order
to prevent malfunctions or failures.
- Some exterior lighting functions can be
adjusted

tion while the vehicle's lights are turned
on, a buzzer sounds as long as the driv­

- In cool or damp weather, the ins ide of
the headlights, turn signals and tail lights can fog over due to the tempera­
ture difference between the inside and
outside. They will clea r shor tly after
switching them on. This does not affect
the service life of the lighting.

_& WARNING
-The rain sensor is only intended to assist
the driver. The driver is still responsible
for manually switching the wipers on ac­ cording to the visibility conditions.
- The windshield may not be treated with

agents. Unfavorable conditions, such as
wetness , darkness, low sun, can result in
increased glare. Wiper blade chatter is
also possible.
- Properly functioning windshield wiper
blades are required for a clear view and
safe driving ¢
page 57, Replacing
windshield wiper blades.
(D Note
- In the case of frost, check whether the
windshield wiper blades are frozen to
the windshield. Switching on the wind­
shield wipers can damage the wiper blades!
- Prior to using a car wash, the windshield
wiper system must be switched
off (lever
in position @). This helps to prevent un­
intentional switching on and damage to
the windshield wiper system .
- The windshield wipers are switched
off
when the ignition is turned off . Activate
the windshield wipers after the ignition is switched back on by moving the wind­
shield wiper lever to any position.
- Worn or dirty windshield wiper blades result in streaking . This can affect the
rain sensor* function . Check your wind­
shield wiper blades regularly.
- The washer fluid nozzles of the wind­
shield washer system are heated at low
temperatures when the ignition is on.
- When stopping temporarily, (e.g . at a
traffic light) the set speed of the wind-

90 Audi adaptive cruise control and braking guard
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 regulating 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 he lps to make driv­
ing more comfortable on long highway
stretches.
The braking guard system can warn you about
an impending collision and initiate braking
maneuvers
c:::> page 96.
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 co ntrol
Fig. 103 Front of the vehicle: Position of radar senso r
The area that contains the radar sensor
c:::> fig. 103 must never be cove red by stickers
or other objects or obstructed with dirt, in­
sects, snow or i ce that will interfere with the
adaptive cruise control system and braking
guard. For information on cleaning, refer to
c:::> page 184. The same applies for any modifi­
cations made in the front area . T
he function of the adaptive cruise cont rol
system and braking guard is limited under
some condit ions:
- Objects can only be detected when they are
within sensor range
c:::>page 92, fig . 106.
-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.
- Some kinds of vehicles are hard to detect;
for examp le motorcycles, vehicles 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 91.
-Stat ionary objects c:::> page 91 .
A WARNING
-
Always pay attention to traffic when adap-
tive cruise contro l is switched on and brak­
ing guard is active. As the driver, you are
still respons ible for starting and for main­
tain ing speed and distance to other ob­
jects. Braking guard is used to assist you.
The driver must always take action to avoid
a col lision. The driver is always responsible
for braking at the correct time.
- Im proper use of adaptive cruise con trol
can cause collisions, other accidents and
serio us personal injury.
- Never let the comfor t and convenience
that adaptive cruise control and braking
guard offer distract you from the need to
be alert to traffic conditions and the
need to remain in full control of your ve­
h icle at a ll times,
- Always remember that the adaptive
cru ise contro l and brak ing guard have
lim its -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 or disabled vehicle.
If registered by the radar sensor, vehicles
or obsta cles that are not moving can
trigger a co llision warning and if

Audi adapt ive crui se c ontrol an d bra kin g guard 91
confirmed by the video camera, an acute
collision warning.
- For safety reasons, do not use adaptive
cruise control when driving 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 conditions cou ld result in a co lli­
sion.
- Switch adaptive cruise control off tempo­ rar ily when driving in turning lanes, on
expressway exits or in cons truction
zones. This prevents the vehicle from ac­ celerating to the set speed when in these
situations.
- The adaptive cr uise control system wi ll
not brake by itse lf if you p ut your foot on
the accelerator pedal. Doing so can over­
ride the speed and distance regulation .
- When approaching stationary objects
such as stopped traff ic, adaptive cruise
control will not respond and braking
guard w ill have limited function.
- The adaptive cruise control system and
braking guard do not react to people, an­
ima ls, objects crossing the road or on­
coming objects.
- The function of the radar sensor can be
affected by reflective objects such as
guard rails, the entrance to a tunnel,
heavy rain or ice.
- Never follow a ve hicle so closely that you
cannot stop your vehicle safely. The
adaptive cruise cont ro l cannot slow or
brake the veh icle safely when you follow
ano ther veh icle too closely. Alway s re­
member that the automatic braking
function cannot bring the vehicle 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 . That could affect the adaptive cruise control
system and braking g uard.
Have your authorized Audi dea ler or au­
thorized Audi Service Facility chec k their
funct ion.
In curves

F ig . 1 04 Examp le : driv ing into a curve
When driving into a curve ¢ fig. 104 and out
of a curve, the adaptive cru ise contro l may re­
act to a vehicle in the next lane and app ly the
brakes. You can override or prevent the brak ­
ing by pressing the accelerator pedal briefly.
Stationary objects
Applies to vehicles: wit h Audi adapt ive cr uise contro l
F ig . 1 05 Examp le: objec t chang ing la n es and stat ion­

The adaptive cruise control system only reacts
to objects that a re mov ing or that the system
has a lready detected as moving . For examp le,
if a ve hicl e@ , which has already been detec t­
ed by the adaptive cru ise con trol , turns or
changes lanes and another stationa ry vehicle
@ is located in front of that vehicle, the sys­
tem will not react to the stationary vehicle.
