Audi braking guard
App lies to vehicles: with Adaptive Cruise Contro l
Description
Audi braking guard warns you of a possible collision with
a moving vehicle up ahead.
F ig. 180 Disp lay in t he
i nstrumen t cluster
The Audi braking guard is active from a speed of approx. 20 mph
(30 km/h) and works within the system limits=>
page 165 even when
the Adaptive Cruise Control is deactivated.
A radar sensor is built into the front of the vehicle=>
page 154,
fig. 160. 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 been taken, the system can recognize a possib ly hazardous s ituation, for example, when a vehicle up
ahead in your lane of travel sudden ly brakes or when your own
vehic le is mov ing at high speed towards a much s lower vehic le up
ahead. As soon as the system senses that a possible collision with
t he vehicle up ahead can only be avoided by immediate full brake
application or by an avoidance maneuver, a warning appears.
The system has a default response time to be able to signal before a co llision occurs. This system response time is automatica lly
reduced if you acce lerate 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 deact
ivated if you
begin to overtake with full acceleration.
The system can make you aware of two different hazardous situa ­
t ions:
Distan ce
The distance warning is g iven if the system calculates that there is
not enough distance to the vehic le up 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 comes on in the instru ­
ment cluster=> fig. 180.
If the vehicle ahead brakes sharply, Audi braking guard cannot help
you to avoid a co llision, even in the case of an immed iate response .
T ake immediate action to avoid the collision and increase the
distance to the vehicle up ahead .
Speed
If there is a much slower vehicle moving up ahead in your lane, or if
the vehic le ahead brakes sharply, the Aud i braking guard calculates
t he point from which a co llision can only be avoided by full braking
or by an avoidance maneuver. If a warning does sound, a possible
collision with the vehicle in front can only be avoided through an
evasive maneuver or by braking.
The warning is given in two stages :
• Pre-warning: A visual disp lay appears in the instrument cl uster
and a warning tone sounds.
• Acut e warning : If you do not respond to the pre -warning, the
second stage warning is given . A quick brake application helps to
direct your attention to the road and traffic situation .
Under heavy braking, the brake assistant::::>
page 154also he lps you
benefit from maximum braking efficiency. _..

& WARNING
Inattention can cause collisions, other accidents and serious
personal injuries.
• Always pay close attention to the traffic , even when the Audi
braking guard is switched on. The Audi braking guard provides a
warning but does not brake the car for you. You must apply the
brakes yourself!
• Always keep the safe and legal distance between your vehicle
and vehicles up ahead.
• Audi braking guard works within limits and will not respond
outside the system limits, for example when approaching a
stopped vehicle or stationary obstacle (end of a traffic jam or
vehicle that has broken down in traffic ).
• Always remember that the radar sensor for the Audi brak ing
guard works within defined detection and range limits that may
prevent the proper detection of other vehicles .
• The radar sensor's function and range can be reduced by rain,
snow and heavy spray . Moving vehicles up ahead may not be
promptly detected or may not be detected at all.
• Always pay careful attention to the traffic situation and be
ready to intervene and be ready to take complete control when ­
ever necessary .
• Reflective surfaces including crash barriers or tunnel entrances
may impair the function of the radar sensor . •

Audi lane assist
Lane assist
Applies to veh icles : with lane assist
Description
Lane a ssist helps you keep y our vehicle in your lane .
Lane assist uses a camera to detect lane boundary lines. If the
system detects that your vehicle is about to leave a lane boundary
line, the steering wheel
vibrates to alert the driver. If lane assist
detects boundary lines on both sides of the vehicle's lane, the
system enters active standby mode, which is indicated by the green
indica tor light /: on the instrument cluster .
I f the system is in active standby mode and the turn signal is acti­
vated before driving ov er the boundary line, the warning does not
occur since the sys tem allows for intenti onal lane changes.
The system is designed for driving on freeways and expanded high ­
ways and t hus works on ly at speeds of 40 mph (65 km/h) or mo re .
& WARNING
• Lane ass ist will not k eep your vehicle in your lane. The sy stem
only warns the d riv er w hen t he vehicle i s le av ing the lan e. The
driv er is alway s re spon sible for keeping the vehicle in the lane.
• The camera is not able to d ete ct all lane boundary lines and in
s o me cases might al so dete ct lane str ucture s or objects as
boundary lines . This c an le ad to in corre ct wa rning s or warnings
that fa il to go off at all .
• The camer a's visibili ty ca n be i mpaired by vehi cle s ahe ad of
you , for instan ce, or by rain , snow , h eavy spray or li ght shining into
th e cam era lens . Thi s can ca use lane as sis t to f ail to d ete ct

-Audi lane
assist --------------------
I Not ready: The yellow indicator light shows that the system is
turned on but unable to send a warn ing. This can be due to the
following:
• There are no boundary lines, or there is on ly one boundary line
present .
• The boundary lines are not detected (e.g. due to snow, dirt, wet
conditions or light shining into the camera lens).
• More than two boundary lines (such as at construction sites) are
located in the vehicle's lane.
• The vehicle's speed is below the speed needed to activate it,
which is about 40 mph (65 km/h).
• The lane is narrower than about 8 ft . (2.5 ml, or wider than about
16 ft. (5 ml.
• The curve is too sharp.
Notes on the instrument cluster display
When the lane assist turns off automatically, the instrument cluster
indicator goes out and one of the following messages appears on
the display:
Audi lane assist not available: Currently no sensor vision
This message appears when the camera can no longer function
because it cannot detect the boundary lines. This may be due to the
following :
• The exterior s ide of the camera viewing window=>
page 171,
fig. 183 is covered with dirt or ice. Clean this part of the windshield.
• The camera v iewing window is fogged up on the inside. In this
case, wait until the fog disappears before turning lane assist on
again.
• The system was unable to detect boundary lines over an
extended period of time due to road conditions (such as snow­
covered lanes). Do not turn lane assist on again until the lines can
be more easily detected.
Audi lane assist not available
A temporary malfunction is preventing lane assist from operating .
Try turning on lane assist again a t a later time.
Audi lane assist: system fault
The system should be checked by an authorized Audi dealer or other
qualified workshop .
[ i ] Tips
• Make sure that the camera viewing window:::> page 171, fig. 183
is not covered by stickers or similar objects .
• Always keep the camera viewing window clean. This can usually
be done by operating the windshield wipers. •

Earl y:
This setting warns the driver before a wheel touches the
detected lane boundary line. The warning depends on the vehicle's
angle as it approaches the boundary line . If you approach a
boundary l ine gradua lly, the warning will occur ear lier. If you
approach the boundary line at a very sharp angle, the warning wi ll
occur just before a whee l touches the line.
Adapti ve : In this setting, the warning time adjusts to the character ­
istics of the road and the vehicle speed. The warning occurs later for
curves and occurs earlier for straight stretches of road. The warning
occurs later on narrow roads than on wide roads.
Late: This setting warns the driver when a whee l drives over the
detected lane boundary line.
Se ttin g th e steering wheel vibration
When adjusting the steering wheel vibration, the steering wheel
vibrates so that you can check the intensity you have set.
[ i ] Tips
• When making the adjustment, lane assist is not activated . The
steering whee l vibrates briefly only to assist you in changing the
setting .
• Your settings are automatically stored and assigned to the
remote contro l key being used. •

& WARNING
• Improper reliance on the side assist system can cause colli­
sions and seriou s per sonal injury:
- Never rely only on side assist when changing lanes .
- Always check rear view mirrors to make sure that it is safe to
c hange lanes.
• Side assist cannot detect all vehicles under all conditions­
danger of accident!
• Side assist cannot detect vehicles in time to alert you when
they approach from behind at very high speed , or fall 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 veh icles or , in some cases, not detecting
them at all . Always keep an eye on the direction you are traveling
and the relevant area around the vehicle.
• Please note that side assi st indicates there are approaching
vehicles, or vehicles in your bl ind spot , only after your vehicle has
reached a driving speed of at lea st 19 mph (30 km /h).
• Side assist signal does not work around tight corners (turning
radiu s less than 328 feet , or 100 m l.
• Side assist is no replacement for the driver's full attention . The
d river alone is responsible for lane changes and similar driv ing
maneuvers. Always keep an eye on the d ire ction you are travel ing
and the relevant area around the vehicle .

General information
Side assist has lim its and cannot detect vehic les under all road and
weather conditions. P lease remember system limitations and
never
rely on the system, especially when:
• driving through curves=>
page 181,
• lanes are of different widths=> page 181. •
Ap plie s to vehicles: with side ass ist
When driving through curves
Side assist cannot detect vehicles in curves with a turning radius of
less than 328 feet (100 m).
When driving through a curve , it is possible that side assist may
register a vehicle two lanes

Side assist's detection area is designed to cover lanes of standard
width to the le ft and right o f your trave l lane, depending on whethe r
you drive in the center of your lane or c loser to the edge.
If you drive in narrow lanes, side assist's detection area may also
inc lude other lanes -especially if you tend to dr ive on the edge o f
your lane=> fig . 196. Under these conditions, vehicles can also be
de tected tha t are two lanes away, and s ide assist then could switch
between the informational and warning stage signa ls.
When d riving in very wide lanes, vehicles in the adjacent lane may
not be detected because they are not inside the detection area. •
