Audi lane assist -________________ lff'II
Not ready: The yellow indicator light shows that the system is
turned on but unable to send a warning. This can be due to the
following:
• Th ere are no boundary lines, or there is only 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.
• Th e vehicle's speed is below the speed needed to activate it, which
is about 40 mph (65 km/h) .
• Th e lane is narrowe r than about 8
ft. (2.5 m), or wider than about
16 ft. (5 m).
• 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 fo llowing messages appears on the
display:
Audi lane assist not available: currently no sensor vision
Thi s message appears when the camera can no longer function
because it cannot detect the boundary lines. This may be due to the
following:
• Th e exte rior side of the camera viewing window=>
page 134,
fig. 127 is covered with dirt or ice. Clean this part of the windsh ield.
• Th e came ra viewing window is fogged up on the inside. In this
case, wait until the fog disappears before turning lane assist on
again.
• Th e system was unable to detect boundary lines over an extended
period of time due to road conditions (such as snow-cove red lanes).
Do not turn lane assist on aga in until the lines can be more easily
detected.

MMI settings
You can use the fv1fv1I to adjust the warning time and
steering wheel vibration.
-Select: Function button [CAR ]> Systems *> Audi lane
assist.
Setting the warning time
Early: 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
line gradually, the warn ing will occur earlier. If you approach the
boundary line at a very sha rp angle, the warn ing will occur just befo re
a wheel touches the line.
Medium : In this setting, the warning time adjusts to the characteris­
tics of the road and the vehicle speed. The wa rning occurs later fo r
curves and occurs earlier for straight stretches of road . The warning
occurs later on narrow roads than on wide ro ads.
Late : This setting warns the driver when a wheel dr ives over the
detected lane boundary line.

& WARNING
• Imp roper reliance on the side assist system can cause collisions
and seriou s per sonal injury:
- Never rely only on s ide ass ist when changing lanes.
- Alway s che ck rear view mirror s to m ake sure that it i s safe to
change lanes.
• Side a ssist cannot detect all vehicles under all condition s­
danger of accident!
• Side a ssi st cannot detect vehicle s in time to alert you when
they approach from beh ind at very high speed, or fall drop back
very quickly .
• The radar sen sor's
v is ion can be reduced or entirely blocked by
rain , snow, and heavy spray . This can result in side as sis t not
adequately detecting vehicle s or , in some cases, not detecting
them at a ll. Alway s keep an eye on the dir ection you are traveling
and the rele vant area around the vehicle.
• Please note that side assist indicates there are approaching
vehicles , or vehicles in you r blind spot, only after you r vehicle has
reached a driving speed of at lea st 19 mph (30 km/h).
• Side assist signal doe s not work around t ight corners (turning
radius les s than 328 feet , or 100 m).
• Side assist is no replacement for the driver 's full attention . The
driver alone is respon sible for lane change s and s imilar driving
maneuvers. Always keep an eye on the direction you are traveling
and the relevant area around the vehicle.
0 Note
• T o ensure that you do not adversely affe ct s ide as sist , do not block
the area on the rear b umper where the radar sensors are located with
fo reign objects (such as st ic kers or b icycle ra cks).
• Make s ure that the signal light on the o utside mi rror is not

The detection~ page 138, fig. 131 of the radar sensor detection
area is made up of :
• the approach area (light green area)
(D, about 230 feet (70 m)
behind the vehicle, and
• the "blind spot" (dark green area)@.
The radar sensors cover the adjacent left and right lanes. Other lanes are
not cove red by the radar sensors.
rn Tip s
Side assist does not measure act ual lane width. The system assumes
a fixed lane w idth. Detection in the left and right lanes is based on
this assumed lane w idth. When driving on narrow roads or when
driving to the left or right of the center of a travel lane, it is possible
that vehicles will be detected that are
not in the lane next to the lane
you are using~
page 143. •
Applie s to ve hicl es: w ith s id e a ssist
Operation
Side assist compares the distance and difference in speed of detected
vehicles with the speed of your vehicle . Whenever the difference in
speed and distance is registered as notab le if you were to change
lanes, a signa l light appears on the respect ive m irror .
The signa l can light up if you are passed by a vehicle or if you are
passing another vehicle.
If you pass another vehicle slowly (d ifference in speed less than 9
mph, or 15 km/h) , the signa l light will come on as soon as the other
vehicle is in your blind spot and is detected by side ass ist . When the
difference in speed is greater, the signal light wi ll not come on. •

Informational and alert stage signals
S ide assis t has two signa l st ages:
• the informational stage signal, and
• t he ale rt stage signal.
S ide assist helps you by using the appropr iate s ignal stage,
depending on whether or not you have activated the turn signal, and
thus have indicated that you are or are not changing lanes .
Informat ional stage signal
As long as you have not activated the turn signal, side assist informs
you of detected vehicles that are registered as being in a notable loca­
tion if you were to change lanes . Wheneve r the detected vehicle 's
difference in speed and distance is registered by side assist as
notable, the signal l ight on the respective m irror produces muted
illumination .
Th e br ightness of the info rmationa l stage signal is designed no t to be
as intense, so that it does not interfere w ith your v iew of the road
when you are driving and have no in tention of chang ing lanes. When
you look in the outside mirror, you can clearly see the informat ional
stage signal.
Alert stage signal
Whe n you act ivate the tu rn s ignal, a nd side assist has de tected a
vehicle in a notable location on that particular side, the signal light on
this side mirro r flashes b rightly. The repeated brief and bright
flash ing of the alert stage signal reminds you to carefully check
traffic to the rear in the outside mirror and over your shoulder, so t hat
you can safely complete the lane change~

Description
The rear acoust ic par king assist sys tem determines the d ista nce of
the vehicle from an obstacle using ultrason ic sensors . There are 4
sensors in the rear bumper .
T he range at which the sensors start to measure is
about :
To the side

Warning tones
Distance warning is given by warning tones which are generated by
t he rear signa l generator. The volume and the p itch o f the warning
tones can be adjusted in the MMI
~ page 161 .
Reversing
Distance warning when reversing starts when an obstacle is detected
in the range o f the pa rking assist system. As the d istance decreases,
the time interval between the audible tones becomes shorter .
When the distance is less than 1ft (0.30 m), the tone becomes
c ont inuous. At this point you should stop back ing up.
