_& 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 bridges
and overpasses, could be ice covered and
slippery even at an outside temperature
above 41 °F
(+5 °() .
- Always remember, even if the "snow­
flake" symbol (ice warning) does not ap­
pear in the d isplay, black ice could be on
the road .
- Always reduce your speed and drive with special care in cold weather cond itions
when the chance of encountering icy
road surfaces increases.
(D Tips
-At temperatures below 14 °F (+ 5 °C) a
snowf lake symbol appears ahead of the
temperature display. It is intended to re­
m ind the driver to pay special attention
to
ice on the road c::> ,&. If the vehicle is
stationary, or if you are driving at a very
low speed, the temperature shown in the
display might be slightly higher than the
actual outs ide temperature. This is .,.

94 Audi adapti ve cruise control and bra king gu ard
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 lat ing 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 helps to make driv­
ing more comfortable both on long highway
stretches and in stop-and-go traffic.
The braking guard system can warn you about
an impending collision and initiate braking
maneuvers¢
page 100.
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. 93 Front of th e veh icle: senso rs and video camera
The areas that conta in the radar and ultrason­
ic sensors and the v ideo camera ¢
fig. 93
must never be covered by stic kers or other ob­
jects or obstructed w ith dirt, insects, snow or
i ce that will interfere with the adaptive cruise
control system and braking guard. For infor­
mation on cleaning, refer to¢
page 216. The same applies for any modifications made in
the front area.
T he function of the adaptive cru ise contro l
system and braking guard is limited under
some cond itions:
- Objects can only be de tected when they are
w ith in sensor range¢
page 96, fig. 96.
- The system has a limited ability to detect
objects that are a short d istance ahead, off
to the side of your vehi cle or mov ing into
your lane.
- Some kinds of ve hicles are hard to detect;
for examp le motorcycles, veh icles 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

& WARNING
A lways pay attention to traffic when adap ­
tive cruise contro l is switched on and brak­
ing g uard is active. As the dr iver, you are
still respons ible for starting and for main­
taining speed and distance to other ob­
jects. Braking guard is used to assist you .
The dr iver must a lways take action to avo id
a collis ion . The driver is a lways respons ible
for braking a t the co rrec t time.
- Imp roper use of adaptive cru ise control
can cause collisions, other acc idents and
serious pe rsonal in jury.
- Never let the comfort and convenience
that adaptive cruise control and braking gua rd offer d istract you from the need to
be alert to traffic condit ions and the
need to rema in in fu ll control of your ve­
h icle at a ll times,
- Always remember that the adaptive
cruise control and braking guard have
limits -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 o r disabled vehicle.

Descript ion
Applies to vehicles: with Audi adaptive cruise control
Fig . 10 3 Instrumen t cl uste r: approach warn ing
Braking guard uses radar sensors and a video
camera . It also functions within the lim its of
the system when adapt ive cruise control is
switched off .
What can braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes sud­
denly or if your own veh icle is traveling at a
h igh speed and approachi ng a veh icle up
ahead that is moving more slowly . Bra king
g ua rd does not react if it can not detect th e
situa tio n.
The system advises you of various situations:
- The
distance warning is given if you are too
close to the vehicle ahead for a long time. If
the vehicle ahead brakes sharply, you will not be able to
avoid a coll is io n. The indicator
li ght
I in the display comes on .
- The
approach warning is g iven when a de ­
tected veh icle up ahead in your lane is
mov ­
ing much more slowly than you are o r if it
brakes sha rply . W he n this wa rning is giv en,
it may only be poss ible to avoid a collisio n

- If a coll is ion is imm inent, the sy stem wi ll

- If you do no t re act to the acu te w arning,
bra king g uard can brake w it h increas ing
force w it h in the lim its of the system . This
red uces the vehicle speed in the event of a
co llision.
- The system can initiate maximum b ra ki ng

at high speeds occurs only in vehicles with
ada ptive cr uise control a nd side assist (pre
sense plus) .
- If the brak ing guard senses that yo u are not

Which function s can be controlled?
You can switch braking guard and the dis­
tance/approach warning on or off in the M MI

A WARNING
-
Lack of attentio n can cause collisions, oth-
er accidents and serio us pe rsonal i nju ries.
Th e braking gua rd is an assist system and
c an not preve nt a collision by it self. T he
d rive r m ust always in tervene. The dr ive r is
a lway s respon sib le f or br aki ng at the cor­
r e ct t ime.
- Always p ay clos e atte ntio n to traffic,
even when the braking guar d is swi tched
on. Be ready to in te rvene and be re ady to
take c omp lete contro l whenever necessa­
ry. Always keep the safe and legal dis­
tance between your ve hicle and veh icles
up ahead.
- Bra king guard works within limits and
w ill not respond outside the system lim­
its, for examp le w hen approachi ng a
stopped vehicle or stationary obstacle ..,.

Audi lane assist Lane assist
De script ion
App lies to vehicles: with la ne ass ist
Lane assist helps you keep your vehicle in your
lane.
Lane assist detects lane marker lines within
the limits of the system using a camera in the
windshield. If you are approaching a detected
lane marker line and it appears likely that you
will leave the lane, the system will warn you
with a light vibration . Lane assist is operable
when the line marking the lane is detected on
at least one s ide of the vehicle.
The system will not warn you before crossing
a lane marker line if you have activated the
turn signal. In th is case, it assumes that you
are changing lanes intent ionally.
The system is designed for driv ing on free­
ways and expanded highways and thus works only at speeds of 40 mph (65 km/h) o r more .
_& WARNING
-Lane assist will not keep your veh icle in
your lane. The system only warns the
driver w hen the veh icle is leaving the
lane. The driver is always responsible for
keeping the vehicle in the lane.
- The camera is not able to detect all lane
boundary lines and in some cases might
also detect lane structures or objects as
boundary lines. This can lead to incorrect
warnings or warnings that fail to go off
at all.
- The camera's visibility can be impaired by
vehicles ahead of you, for instance, or by
rain, snow, heavy spray or light shin ing
in to the camera lens. This can ca use lane
assist to fa il to detec t boundary li nes.

• Read y:
The green indicator light shows
that the system is ready to use. The system
can now war n you if you are about to c ross a
known lane marker line.
• Not ready : The yellow indicator light
shows that the system is t urned on but unable
to send a warning. This can be due to the fol­ low ing:
- 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, di rt, water or backlighting) .
- The vehicle's speed is below the speed need­ ed to activate it, wh ich is about 40 mph (65
km/h).
- The lane is narrower than about 8 ft. (2.5
m) .
