The text messages and symbols shown in this area of the
display are not displayed permanently .
Time intervals (such as e::::, ____ e::::,)
Fig. 124 System
status indicator
The different symbols for the time intervals appear if you change the
sett ings => fig. 124 .
Th e text message ... (three white dots) appears if a setting cannot be
implemented with the operating lever. The following are possible
reasons:
• If you pull the control lever towa rds you to resume speed but no
requested speed was set .
• If you push the lever up to increase (or down to reduce) speed
when no speed has been set previously.
• If you push the lever up to increase (or down to reduce) speed and
this speed is outside the range from 20 to 95 mph (Canada mode ls:
30 to 150 km/h) .
ACC functionality Limited
The text message ACC functionality limited appears when the ACC
system does not detect any objects over an extended time period. For
the time being, the d istance to veh icles up ahead is not being
Controls and equip ­
ment Safety first
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 s ide of the road (e .g . guard rails, traff ic s igns,
trees). As soon as a vehicle is detected by the system again, it returns
t o its contro l range and the text message disappears.
The ACC sensor is located in the r ig ht front trim grille
=> page 116,
fig. 114 . If there is a loss of operation due to heavy contamination,
this area should cleaned to restore proper operat ion .
ACC not available
The text message ACC not available appears, for examp le, if the
t empe rature of the brakes is excessive. Adaptive cruise control is
temporarily not available. A warning tone sounds as a rem inder .
ACC not available!
The text message ACC not available! appears in the event of a
ma lf unct ion. Adaptive cruise control is turned off. A warn ing tone
sounds as a reminder . Have the system inspected by a qualified deal­
ersh ip.
ACC sensor blocked !
The text message ACC sensor blocked ! appears 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
limited), the system w ill also takes into consideration the outside
temperature and/or the windshield wiper operation .
Th e ACC sensor is d irty or blocked (e.g. leaves, snow).
Th e sensor should be cleaned to restore prope r sensor funct ion
=> pagell6,fig.114.

Parking brake!
The text message Parking brake! appears if emergency braking was
manually initiated with the Electromechanical Parking Brake (EPB).
The adapt ive cruise control is turned off. This is accompanied by a
warning tone.
Stabilisation program
The text message Stabilisation program appears if the Elect ronic
Stabilization Program (ESP) has intervened. In this case the adaptive
cruise control is automat ica lly 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~
page 119, "How is
the speed stored?" and~
page 119, "Changing stored speed".
Speed too low
The text message Speed too low appears if the current speed is too
low
to set or to hold the requested speed.
When setting a desired speed, it must be at least 20 mph (30 km/h).
At speeds below 12 mph (20 km/h), the cruise control is turned off .
In speeds over 95 mph (150 km/h), the system remains active and
resumes the speed of 95 mph (150 km/h) if the driver removes the
foot from the accelerator .
Selector lever position!
The text message Selector lever position! appears when the selector
lever is moved to position
N. In this position , adaptive cruise control
is not available .•

Driver intervent ion prompt
The driver intervention prompt calls on the driver to take
over the situation .
Fig. 125 Instrument cluster: Driver intervention prompt
In certain situations, the braking power of the adaptive cruise control
is not sufficient to maintain an adequate distance from the object
ahead . In th is s ituation, the adaptive cruise control calls on you as the
driver to take action.
The
driver intervention prompt alerts you visua lly and audibly.
• A red vehicle is show n in the instrument cluster display
=> fig . 125.
• The text
DISTANCE! appears in the status line .
• T he indicator light in the Instrument cluste r blinks red.
• A warning tone sounds.

[I) Tips
• If the adaptive cruise control initiates brak ing, the hydraulic brake
system is under pressure. Therefore, the brake pedal distance is
shorter and the peda l "feels" harder.
• Adaptive cruise control is switched off after pressing the foot­
brake. The speed saved up this poi nt can be resumed.
• To resume the saved speed, release the brake pedal and press the
control lever:::::,
page 120, "Turning adaptive cruise control off
temporari ly".
• If you use the accelerator to go faster than the speed of the object
ahead of you, the
driver intervention prompt will not be accompa­
nied by a warn ing s ignal.
• If the speed you prev iously set is exceeded, the indicator light in
the speedometer will switch off .•

General information
Some driving situations which affect the function of the
radar sensor are described below.
When driving, the adaptive cru ise contro l is governed by physical and
system-specified limits. Also, under certain circumstances, the ACC
system may react unexpectedly or late from the driver's point of view.
Therefore, always be attentive and intervene, if necessary:
• when driving around curves :::::,
page 128
• when vehicles in front are not in line with your vehicle:::::, page 128
• when other vehicles are changing lanes:::::, page 128
• when other vehicles are difficult to detect :::::, page 129.
& WARNING
The radar sensor's vision can be reduced by rain, snow and heavy
spray. This can result in vehicles driving ahead being inadequately
detected or, in some circumstances , not detected at all. If neces­
sary, take action yourself!•

The Audi braking guard is active from a speed of approx. 20 mph
(30 km/h) and works within the system limits=>
page 12 7 even when
the adaptive cruise control is deactivated.
A radar sensor is built into the front of the vehicle=>
page 116,
fig. 114. The system is intended to measure the distance to reflective
surfaces. If a measurement is not possible, the system does not
respond.
When the measurement has taken place, the system can assess a
hazardous situation, when a vehicle ahead suddenly brakes or when
your own vehicle is dr iving at high speed towards a much slower
vehicle ahead. As soon as the system assumes that a possible colli­
sion w ith the vehicle ahead can only be avoided by immediate all-out
braking or by an avoiding maneuver, a warning appears .
Th e system has a pre-set response time to be able to warn in good
time. This system response time is automatically reduced if you accel­
erate actively, for example to join a highway. 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 full accelerat ion.
The system draws your attention to two different hazardous situa ­
tions:
Distance
Th e distance wa rning is issued in the event of inadequate distance to
the vehicle ahead a period of more than S seconds. If the distance is
less than 30 feet (9 meters) at SO mph (80 km/h), for example, an
optical display is faded in on the instrument cluster=>
page 129,
fig. 133.
If the vehicle ahead brakes sharply, a collision cannot be avoided,
even in the case of an immediate response. In this case, increase the
distance to the vehicle ahead.
Speed
If there is a much slower vehicle ahead in your lane, or if the vehicle
ahead brakes sha rply, the Audi braking guard calculates 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 possible collision with
the vehicle in front can be avoided through an evasive maneuver or by
braking.
Th e warn ing is given in two stages:
• Pre-warning: An optical display appears in the instrument cluster
and a warning tone sounds.
• Acute warning: If you do not respond to the pre-warning, the
second stage, the acute warning, is issued. A brake jolt reminds you
to concentrate on the road again.
Under heavy breaking, brake assist =>
page 245 also helps you obtain
maximum braking effic ien cy.
& WARNING
Always pay attention to traffic, even when the Audi braking guard
is switched on. You are always resp onsible for
your speed and the
distance between your vehicle and other vehicles.
• Always keep the legally stipulated safety distance between
your vehicle and the vehicle 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
traffic jam or breakdown vehicle).
• Please observe that the Audi braking guard is subject to restric­
tions in narrow bends due to the field of vision of the radar sensor.
This may possibly lead to obstacles not being detected.
• The radar sensor's
vision can be reduced by rain, snow and
heavy spray . This can result in vehicles driving ahead being inade­
quately detected or, in some circumstances, not detected at all.
Always watch where you are driving.
• Reflecting objects such as e.g. crash barriers or the entrance to
a tunnel may impair the function of the radar sensor.•
