Audi lane assist
Lane assist
Applies to vehicles: with lane assist
Description
Lane assist helps you keep your 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
indicator light/: on the instrument cluster.
If the system is in active standby mode and the turn signal is acti­
vated before driving over the boundary line, the warning does not
occur since the system allows for intentional lane changes.
The system is designed for driving on freeways and expanded high­
ways and thus works only at speeds of 40 mph (65 km/h) or more.
& WARNING
• Lane assist will not keep your vehicle in your lane. The system
only warns the driver when the vehicle is leaving the lane. The
driver is always responsible for keeping the vehicle in the lane.
• The camera is not able to detect all lane boundary lines and in
some cases might also detect lane structures or objects as
boundary lines. This can lead to incorrect warnings or warnings
that fail to go off at all.
• The camera's visibility can be impaired by vehicles ahead of
you, for instance, or by rain, snow, heavy spray or light shining into
the camera lens. This can cause lane assist to fail to detect
boundary lines. •

I Not re ad y: The yellow ind icator light shows that the system is
t urned on but unab le to send a warning . 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 abou t 40 mph (65 km/h).
• The lane is narrower than about 8 ft . (2 .5 m), or wider than about
16
ft . (5 m).
• The curve is too sharp .
Notes on th e instr umen t clu ste r displa y
When the lane assist turns off automatically , the instrument cluster
indicator goes out and one of the following messages appears on
the display:
Audi lan e assist not available: C urre ntl y no se nsor vis ion
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 151,
fig. 169 is covered with dirt or ice. Clean this part of th e windshield.
• The camera v iew ing window is fogged up on the inside. In t his
case, wait until the fog disappears before turning lane assist on
aga in.
• 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 unti l the lines can
be more easily detected .
Audi lane assist not ava ila bl e
A temporary malfunction is preventing lane assist from operating .
Try turning on lane assist again a t a la ter t ime.
Audi l ane ass is t: sys te m f ault
T he system should be checked by an authorized Audi dealer or other
qual ified workshop .
[ i ] Tips
• Make sure that the camera viewing window => page 151, fig. 169
is not covered by stickers or similar objects .
• Always keep the camera view ing w indow c lean . This can usual ly
b e don e by op erat ing the windshield wipers. •

Setting th e warning tim e
E a rl y:
This setting warns the driver before a wheel touches the
detected lane boundary line. The warning depends on the ve hicle'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 l ine.
A dapti ve : In this setting, the warning time adjusts to the character ­
istics of the road and the vehic le speed. The warning occurs later for
curves and occurs ear lier for straight stretches of road . The warning
occurs later on narrow roads than on wide roads.
Late: Th is setting warns the driver when a whee l drives over the
detected lane boundary line.
Setting th e steering wheel vibrati on
When adjusting the steering whee l vibration, the steering wheel
v ibrates 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
se tting .
• Your settings are automatically stored and assigned to the
remote contro l key being used. •

Position of radar
sensors (not visible on
outside)
Fig . 172 Signal light
on the outside mirror·
driver's side
Side assist uses radar sensors (not visible on outside) => fig. 171 to
help the driver check blind spots, and see what is happening in
traffic behind the
vehicle => page 155, fig. 174.
Signal lights are built into both outside
mirrors=> fig. 172. The
signal light on the left outside mi rror assists when moving over into the left lane and the signal light on the right outside mirror assists
when moving over into the right lane.
The signal light comes on to tell you that side assist has detected a
vehicle on that side and that the position of this other vehicle
should be taken into account if you were to change lanes. This is
called the
informational stage signal=> page 156. The informational
stage signal is designed so that you notice it only when you are
looking in the outside mirror.
When you activate the turn signal and side assist detects a vehicle
in a notable location, the corresponding signal on the outside
mirror flashes briefly and brightly several times. This is the
alert
stage signal
=> page 156. •

• To ensure that you do not adverse ly affect s ide assist, do not
b lock the area on the rear bumper where the radar sensors are
located with foreign objects (suc h as stickers or bicycle racks).
• Make su re that the signal light on the outside mirror is not
b locked by stickers or other items.
[ i ] Tip s
• Side ass ist automatically deactivates if it detects that the radar
sensors are
blocked => page 167. The indicator light on the button
goes out.
• The area on the bumper where the radar sensors are located
must consistently re main free of snow, ice, and heavy so iling so that
side assist can function properly. Follow the additiona l notes on
=> page 761.
• Additiona l tinting on the front side windows can make it harder
to see and correct ly understand the s ignal light on the outside
mirror. •

The detection ~ page 155, fig. 174 of the radar sensor detection
area is made up of:
• the approach area (light green area)
G), about 55 yards (50 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] Tips
S ide ass ist 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 travel lane, it is
possible that vehicles wi ll be detected that are
not in the lane next
to the lane you are
using~ page 160 . •
Applies to vehicles: with side assist
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 notable if you were
to change lanes, a signal light appears on the respective m irror.
The signal can light up if you are passed by a vehicle or if you are
passing another vehicle.
If you pass another vehicle slowly (difference in speed less than 9
mph, or
15 km/h), the signal light will come on as soon as the other
vehic le is in your b lind spot and is detected by side assist . When the
difference in speed is greater, the signal light wil l not come on.•
Applies to vehi cles: with side assist
Informational and alert stage signals
Side assist has two signa l stages:
• the informational stage signal, and
• th e alert stage signal.
Side assist helps you by using the appropriate signa l stage,
depending on whether or not you have activated the turn signal,
and thus have indicated that you are or are not changing lanes.
Informational 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
vehic le 's difference in speed and distance is registered by side
assist as notable, the signa l light on the respective mirror produces
muted il lumination .
The brightness of the informationa l 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.
When you look in the outside mirror, you can clearly see the infor­
mational stage signal.
Alert stage signal
When you ac tiva te the turn signal, and side assis t has detected a
vehic le in a notable location on that particular side, the signal light
on this side mirror flashes brightly. The repeated brief and bright
flashing of the alert stage signal reminds you to careful ly check
traffic to the rear in the outside mirror and over your shou lder, so
that you can safe ly complete the lane
change~ & in "Safety tips"
on page
161.
[ i] Tips
The brightness of the signal light on the outside mirrors can be
adjusted with the MMI
