-
When setting the dista nce, the dr ive r is re­
sponsible for adhering to the respective
national and country-specific regulations .
- F ollowing other vehicles too closely in-
creases the risk of collisions and serious
persona l injury .
- Setting short distances to the traffic ahead red uces the t ime and distance
available to br ing your vehicle to a safe
stop and makes it even more necessary
to pay close attention to traffic.
- Always use good judgment and se lect a
safe following distance for the traffic, road and weather cond itions .

any objects over an extended time period. For
the time being, the distance to vehicles up
ahead is not being controlled. The ACC system
is not switched off, so increased alertness is
required. The following may be reasons for
the text message ACC Functionally limited:
- The ACC sensor is dirty. The ACC system is
not reacting, or is not reacting correctly, to
vehicles traveling ahead .
- It is possible that you are driving on a road
with very light traffic
without anything at
the side of the road (e.g. guard rails, traffic
signs, trees). As soon as a vehicle is detected
by the system again, it returns to its control
range and the text message disappears.
The ACC sensor is located in the right front
trim grille
¢ page 102, fig . 110. If there is a
loss of operation due to heavy contamination,
this area should cleaned to restore proper op­
eration.
ACC not available
The text message ACC not available appears,
for example, if the temperature of the brakes
is excessive . Adaptive cruise control is tempo­
rarily not available. A warning tone sounds as
a reminder.
ACC not available!
The text message ACC not available! appears
in the event of a malfunction. Adaptive cruise
control is turned off. A warning tone sounds
as a reminder. Have the system inspected by a
qualified dealership.
ACC sensor blocked !
The text message ACC sensor blocked ! ap­
pears when the ACC system can no longer
guarantee safe detection of objects. Adaptive
cruise control is turned off. A warning tone
sounds as a reminder.
To decide whether it is necessary to switch off
the ACC (ACC sensor blocked
!) or if it is only a
temporary condition (ACC Functionally limit­
ed), the system will also takes into considera­
tion the outside temperature and/or the wind­
shield wiper operation. The
ACC sensor is dirty or blocked (e.g. leaves,
snow).
The sensor should be cleaned to restore prop­
er sensor function¢
page 102, fig. 110.
Engine speed !
The text message Engine speed ! appears in
vehicles with manual transmission when the driver did not shift up or down in time while
using adaptive cruise control braking or accel­
erating, causing the vehicle to exceed or not
reach the permitted limit speed. This causes
adaptive cruise control to deactivate automat­
ically. A chime sounds as a reminder.
Parking brake!
The text message Parking brake! appears if
emergency braking was manually initiated
with the Electromechanical Parking Brake
(EPB). The adaptive cruise control is turned
off. This is accompanied by a warning tone.
Stabilisation program
The text message Stabilisation program ap­
pears if the Electronic Stabilization Program
(ESP) has intervened. In this case the adaptive
cruise control is automatically turned off. This
is accompanied by a warning tone.
Speed
The set speed in mph (Canada km/h) always
appears when saving or changing the speed in
adaptive cruise control¢

In certain situations, the braking power of the
adaptive cruise control is not sufficient to
maintain an adequate distance from the ob­
ject ahead . In this situation, the adaptive
cru ise control calls on
you as the driver to take
action.
The
driver intervention prompt alerts you vis­
ually and audib ly .
- A red vehicle is shown in the instrument
cluster disp lay

- The indicator light in the Instrument cluster
blinks red.
- A warning tone sounds.

-If the adaptive cruise control initiates
braking, the hydraulic brake system is
under pressure . Th erefore, the brake
pedal distance is shorter and the pedal
"feels" harder.
- Adaptive cruise contro l is swi tched off af ­
ter pressing the footbrake. The speed
saved up this point can be resumed.
- To resume the saved speed, re lease the
brake pedal and press the control lever
¢ page 105, Turning adaptive cruise
control off temporarily.
- If you use the accelerator to go faster
than the speed of the object ahead of
you, the
driver intervention prompt will
not be accompan ied by a warn ing signal.
- If the speed you previously set is exceed­
ed, the indicator light in the speedome­
ter will switch off.

System limitations
General information
App lies to vehicles: with adaptive cruise control
Some driving situations which affect the func­
tion of the radar sensor are described below.
When driving, the adaptive cru ise control is
governed by physical and system-specified
limits. Also, under certain circumstances, the
ACC system may react unexpectedly or late
from the driver's po int of view. Therefore, al­
ways be attentive and intervene, if necessary:
- when driving around curves¢
page 112
-when vehicles in front are not in line with
your vehicle ¢
page 112
-when other vehicles are changing lanes
r:=>page 113
-when other veh icles are difficult to detect
r:=> page 113.
A WARNING
The radar sensor's vision can be reduced by
rain, snow and heavy spray. This can result
in vehicles driving ahead being inade­
quately d etected or, in some c ircumstan­
ces, not detected at a ll.
If ne cess ary, take
a ction yourself!
When driving around curves
Applies to vehicles: with adaptive cruise control
Fig. 122 Vehicle entering a cu rve
Fig. 123 Ve hicle leav ing a cu rve
Entering a curve
When enter ing a curve, the adaptive cruise
control may react to a vehicle in the next lane
and apply the brakes in yo ur vehicle
r:=> fig. 122. The braking action can be overrid­
den by depressing the accelera tor pedal.
Leaving a curv e
At the exit from very long curves the pred ic­
t ive lane reading can cause the adaptive cruise
control to react to another vehicle in the next
lane and apply the b rakes in your vehicle
r=>fig . 123. The braking action can be over rid­
den by depressi ng the acce le ra tor pedal.
, Vehicles offset to one side
Applies to vehicles: with adaptive cruise control

114 Adaptive cruise control
The Audi braking guard is active from a speed
of approx. 20 mph (30 km/h) and works with­in the system limits¢
page 112 even when
the adaptive cruise contro l is deactivated.
A radar sensor is bui lt into the front of the ve ­
hicle
¢ page 102, fig. 110. The system is in­
tended to measure the distance to reflective
surfaces. If a measurement is not possible,
the system does not respond .
When the measurement has taken p lace, the
system can assess a hazardous situation,
when a vehicle ahead suddenly brakes or when
your own vehicle is driving at high speed to­
wards a much slower vehicle ahead . As soon
as the system assumes that a possible colli­
sion with the vehicle ahead can on ly be avo id­
ed by immediate all-out braking or by an
avoiding maneuver, a warning appears.
The system has a pre-set response time to be
able to warn in good t ime . This system re­
sponse time is automat ically reduced if you
accelerate actively, for example to join a high­
way. Braking, transverse acceleration and the
steering angle can lead to a reduced system
response time . The warning is deactivated if
you begin to overtake with fu ll acce leration.
The system draws your attention to two differ­
ent hazardous situations:
Distance
The distance warn ing is issued in the event of
inadequate distance to the veh icle ahead ape­
riod of more than 5 seconds . If the distance is
l ess than 30 feet (9 meters) at 50 mph
(80 km/h) , for example, an optical display is
faded in on the instrument cluster¢
fig. 129.
If the vehicle ahead brakes sharply, a collision
cannot be avoided , even in the case of an im­
mediate response. In this case, increase the
distance to the vehicle ahead.
Speed
If there is a much slower veh icle ahead in your
la ne, or if the vehicle ahead brakes sharply,
the Audi braking guard ca lculates the point
from which a collision can only be avoided by all-out braking or
by an avoiding maneuver. If
a warning does sound, a possib le collision
with the vehicle in front can be avoided
through an evas ive maneuver or by braking .
T he warning is given in two stages:
-Pre-warning: An optical display appears in
the instrument cluster and a warning tone
so unds.
- Acute warning: If you do not respond to the
pre-warn ing, the second stage , the acute
warning, is issued . A brake jolt reminds you
to concentrate on the road again.
Under heavy brea king, brake assist
¢
page 209 also helps you obtain max imum
braking efficiency.
.&_ WARNING ~
Always pay attention to traffic, even when
the Audi braking guard is switched on. You
are a lways responsible for your speed and
the distance between your vehicle and oth·
er vehicles.
-Always keep the lega lly stipulated safety
d istance between your vehicle and the
veh icle ahead • danger of accident!
- The Audi braking guard does not respond
outside the system limits, for example if
you approach a stationary obstacle (end
of a traff ic jam or breakdown vehicle).
- Please observe that the Audi braking
guard is subject to restrictions in narrow
bends due to the field of vision of the ra­
dar senso r. T his may possibly lead to ob­
stacles not being detected.
- The radar sensor's
vision can be reduced
by rain, snow and heavy spray. This can
resu lt in vehicles driving ahead being in­
adequately detected or, in some circum­
stances, not detected at all. Always
watch where yo u are driving .
- Reflecting objects such as e.g . crash bar ­
riers or the entrance to a tunne l may im­
pair the function of the radar sensor .
