The text message ... (three whi te dots) appears if a setting cannot be
implemented with the operating lever . The following are possib le
reasons :
• If you pull the control lever towards 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 .
• I f 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
models : 30 to 150 km/h) .
ACC functi onal it y limited
The text message ACC fun ctio na lit y lim ited appears when the ACC
system does not detect any objects over an extended time period.
For the time being, the distance to vehicles up ahead is not being
Controls and equip ­
ment
controlled . The ACC system is not switched off, so increased alert­
ness is required. The following may be reasons for the text message
ACC Functiona lly limited:
• The ACC sensor is dirty. The ACC system is not reacting, or is not
react ing correctly, to veh ic les traveling ahead.
• I t is possible that you are driving on a road with very light traffic
without anything at the side of the road (e.g. guard rai ls, 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::::>

fig. 122 . If there is a loss of operation due to heavy contamination,
this area should cleaned to restore proper operation .
ACC not available
The text message ACC not available appears , for example, if the
temperature of the brakes is excessive. Adaptive cruise control is
temporarily not availab le . A warning tone sounds as a reminder .
ACC not a vailable !
The text message ACC not ava ila ble! appears in the event of a
malfunction . Adaptive cru ise control is turned off . A warning tone
sounds as a reminder. Have the system inspected by a qua lified
dea lership .
ACC sensor blo cked !
The text message ACC s ensor 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
b locked
!) or if it is only a temporary condition (ACC F unctionally
limited), the system wi ll a lso takes into consideration the outside
temperature and/or the windshield wiper operation.
The ACC senso r is dirty or b locked (e .g . leaves, snow).
The sensor should be cleaned to restore proper sensor function

General information
Some driving situations which affect the function of the
radar sensor are described below.
When driving, the adaptive cruise con tro l is g overned 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 driv ing around curves =>
page 130
• when vehicles in front are not in line with your vehicle
=>
page 131
• when other vehic les are changing lanes=> page 131
• when o ther vehicles a re di fficu lt to detec t=> pag e 131.
& WARNING
The radar sensor's vision can be reduced by rain, snow and heavy
spray . Th is can result in vehicles driv ing ahead being in adequate ly
detected or, in some circumstances, not detected at all. If ne ces ­
sary , take a ction yourself! •

Audi braking guard
Applies to vehicl es: wi th a dapt ive c ruise co ntrol
Description
Audi braking guard warns you of a threatening collision
with a vehicle ahead .
Fig. 142 Display in the
instrument cluster
The Audi braking guard is active from a speed of approx. 20 mph
(30 km /h) and works within the system limits~
page 130even when
the adaptive cruise control is deactivated .
A radar sensor is built into the front of the vehicle~
page 118,
fig. 122. The system is intended to measure the distance to reflec­
tive 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 driving at high speed towards a much slower
vehicle ahead. As soon as the system assumes that a possible colli ­
sion with the vehicle ahead can only be avo ided 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
time. This system response time is automatically reduced if you acce lerate actively, for example to join a highway. Braking, trans ­
verse acceleration and the steering angle can lead to a reduced
system response time. The warning is deactivated if you begin to
overtake with full acceleration .
The system draws your attention to two different hazardous situa ­
tions:
Distance
The distance warning is issued in the event of inadequate distance
to the vehicle ahead a period of more than 5 seconds . If the distance
is less than 30 feet (9 meters) at 50 mph (80 km/h), for example, an
optical display is faded in on the instrument cluster~ fig. 142.
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 sharply, the Audi braking guard calculates the point
from which a collision can only be avoided by all -out braking or by

& WARNING
Always pay attention to traffic , even when the Audi braking guard
is switched on . You are always responsible 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 brak ing 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 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 . •

The system works at speeds faster than 19 mph (30 km/h) .
& WARNING
• Improper reliance on the side assist system can cause colli­
sions and serious personal injury :
- Never rely only on side assist when changing lanes .
- Always che ck rear view mirrors to make sure that it is safe to
change lane s.
• Side assist cannot detect all vehicles under all conditions­
danger of ac cident!
• Side assist cannot detect vehicles in time to alert you when
they approach from behind at very high speed, or f all drop back
very quickly.
• The radar sensor 's
vision can be reduced or entirely blocked by
rain , snow , and heavy spray . This can result in side assist not
adequately detecting vehicles or , in some cases, not dete cting
them at all . Always keep an eye on the direction you are traveling
and the relevant area around the vehicle .
• Please note that side assist indicates there a re approaching
vehicles , or vehicles in your blind spot , only after your vehicle has
reached a driving speed of at least 19 mph (30 km /h).
• Side assist s ignal does not work around tight corners (turning
radius less than 328 feet or 100 m l.
• Side assist is no replacement for the driver's full attention . The
driver alone is responsible for lane changes and similar driving
maneuvers . Always keep an eye on the direction you are traveling
and the relevant area around the vehicle.

The detection => fig . 147 of the radar sensor detection area is made
up of:
• the approach area (light green area)
0, about 230 feet (70 m)
behind the vehic le, and
• the "blind spot" (dark green areal@.
The radar sensors cover the adjacent left and right lanes. Other
lanes are
not covered by the radar sensors.
[ i ] Tip s
Side assist does not measure actual lane width. The system
assumes a fixed lane width . Detection in the left and right lanes is
based on this assumed lane width . When driving on narrow roads or
when driving to the left or right of the center of a trave l lane, it is
possible that vehicles will be detected that are
not in the lane next

Operation
Side assist compares the distance and difference in speed of
detected vehic les with the speed of your vehic le. Whenever the
difference in speed a nd distance is registered as notable if you were
to change lanes , a signal light appears on the respective mirror .
The signal can light up if you are passed by a vehicle or if you are passing another vehicle.
If you pass another vehicle slow ly (difference in speed less than 9
mph, or
15 km/h), the signal light wil l come on as soon as the o ther
vehic le is in your b lind spot and is detected by side assist. When the
difference in speed is greater, the signal light will not come on .•
Ap plies to vehi cles : with si de assi st
Informational and alert stage signals
Side assist has two signal stages:
• t he informational stage s igna l, and
• the alert stage signal.
Side assist helps you by using the appropriate signa l stage,
depending on whether or not you have activated the tu rn signal,
and thus have indicated that you are or are not changing lanes .
Infor mation al stage signal
As long as you have not activated the turn signa l, side assist informs
you of detected vehicles that are registered as being in a notable location if you were to change lanes. Whenever the detected
vehicle's difference in speed and distance is registered by side assist as notable, the signal light on the respective mirror produces
muted illumination.
The brightness of the informational stage signa l is designed not to
be as intense, so that it does not interfere with your view of the road
when you are driving and have no intention of changing lanes. .,
