Some functions and vehicle components are
scanned for their operating status when you
switch the ignition on and whi le you are driv­
ing. Malfunctions or required service proce­
dures are signaled audibly and indicated by
red and yellow illuminated symbols and re­
minders in the d isplay.
A WARNING
--- Never rely exclusively on the outside
temperature display to determine if a
road surface is icy or not. Keep in mind
that road surfaces, especially br idges
and overpasses, could be ice covered and
slippery even at an outside temperature
above 41 °F (+5 °C).
- Always remember, even if the "snow­
flake" symbol (ice warning) does not ap­
pear in the disp lay, black ice cou ld be on
the road.
- Always reduce your speed and drive with
specia l care in cold weather cond itions
when the chance of encountering icy
road surfaces increases.
¢j) Tips
If the vehicle is stationary, or if you are
driving at a very low speed, the tempera­
ture shown in the display might be s light ly
higher than the actual outs ide tempera­
ture. This i.s caused by the heat being radi­
ated from the engine .

-If the power lock ing system should ma l­
function, you can lock the driver's door
using the mechanical key
~ page 3 7.
- If the power locking system should fail,
you can still open the fue l tank flap in an
emergency <=>
page 214.
-You are well advised not to keep valua­
bles inside an unattended vehicle, visible
or not . Even a properly locked vehicle
cannot provide the security of a safe .
- If the LED in the upper edge of the driv­
er's door panel comes on for about
30
seconds after the vehicle is locked, there
i s a malfunction in the power locking or
the anti-theft warning system. Have the
malfunction corrected by an author ized
Audi dealersh ip or qua lified repair fac ili­
ty.

On the road 81
The speed is kept constant by modifying en­
gine power or through an active brake inter­
vention.
_& WARNING
- Always pay attent ion to the traffic
around you when the cruise control is in
operation. You are always responsible for
your speed and the distance between
your veh icle and other vehicles .
- For reasons of safety, cru ise control
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 lani ng) -risk of accident.
- Turn off the cruise control temporarily
when enter ing turn lanes, highway exit
lanes or in construction zones .
- Please note that inadvertently "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 switched off. The other cruise control functions re­
main active as long as the indicato r light
lijj(l )~i~ (US models) li'I (Canadian mod­
e ls ) is on.
@ Tips
-Veh icles with manual transmiss ion: You
can attain the set speed only if the gear
that is currently engaged will allow it, or
if it does not tax the engine and allows i t
to run smoothly. Therefore shift into a
higher or lower gear in a timely manner.
- The brake lights illuminate as soon as
the brakes apply automatically.

Audi adaptive cruise control and braking guard 97
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 lating 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 ¢
page 103.
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. 96 Front of the veh icle: Pos ition of radar sensor
The area that contains the radar sensor
¢
fig. 96 must never be covered by st ickers or
other objects or obstructed with dirt, insects,
snow or ice that will interfere with the adap­
tive cruise control system and Audi braking
guard. For information on cleaning, refer to
¢
page 201. The same applies for any modifi­
cations made in the front area . The
function of the adaptive cruise contro l
system and braking guard is limited under
some cond itions:
- Objects can only be detected when they are
within sensor range
¢page 99, fig . 99.
-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.
- 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¢
page 98.
-Stationary objects¢ page 98.
A WARNING
-Always pay attention to traffic when adap-
tive cruise control is switched on and brak­ ing guard is active. As the dr iver, you are
still responsible for starting and for ma in­
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 collision. The driver is always responsible
for braking at the correct time.
- Improper use of adaptive cruise con trol
can caus e collisions, other accidents and
serious personal injury .
- Never let the comfort and convenience
that adaptive cruise control and Audi
braking guard offer distract you from the
need to be alert to traff ic conditions and
the need to remain in full control of yo ur
veh icle at a ll times,
- Always remember that the adaptive
cru ise contro l and Aud i brak ing guard
have lim its -they will not slow the vehi­
cle down or maintain the set d istance
when you drive towards an obstacle o r
someth ing on or nea r the road that is not
moving, such as vehicles stopped in a
traffic jam, a stalled or disabled vehicle.
If registered by the radar sensor, vehicles
or obstacles that are not moving can
trigger a collision warning and if .,.

98 Audi adaptive cruise control and braking guard
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
hydroplaning). Using the system under
these conditions could result in a colli­
sion.
- Switch adaptive cruise control off tempo­
rarily when driving 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 adaptive cruise control system will
not brake by itself 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 will have limited function.
- The adaptive cruise control system and
braking guard do not react to people, an­
imals, 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 vehicle so closely that you cannot stop your vehicle safely. 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 cannot bring the vehicle to a sudden or emergency stop under these
conditions.
- To prevent unintended operation, always
switch ACC
off when it is not being used.
{[) Note
The sensor can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. That could affect the adaptive cruise control system and braking guard.
Have your authorized Audi dealer or au­
thorized Audi Service Facility check their
function.

Fig. 97 Example: d riving i nto a curve
When driving into a curve ~ fig. 97 and out of
a curve, the adaptive cruise control may react
to a vehicle in the next lane and apply the
brakes. You can override or prevent the brak­
ing by pressing the accelerator pedal briefly.
Stationary objects

The adaptive cruise control system only reacts
to objects that are moving or that the system
has already detected as moving. For example,
if a vehicle @, which has already been detect­
ed by the adaptive cruise control, turns or
changes lanes and another stationary vehicle
@ is located in front of that vehicle, the sys­
tem will not react to the stationary vehicle.
