Not read y: The yellow indicator light shows that the system is
turned on but unable to send a warning. T his can be due to the
following:
• T here 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 const ruct ion sites) are
located in the vehicle's lane .
• T he veh icle's speed is below the speed needed to ac tivate it, which
is about 40 mph (65 km/h) .
• T he lane is narrowe r than about 8
ft . (2.5 m), or wider than about
16 ft. (5 m).
• Th e curve is too sharp.
Note s on the in strum ent clust er displa y
When the lane assist turns off automat ica lly, the instrument cluster
indicator goes out and one of the fo llowing messages appears on the
display :
Aud i lane ass is t not av ailable: Cur rentl y n o sens or v ision
T his message appears when the camera can no longer function
because it cannot detect the boundary lines. This may be due to the
following:
• T he exte rior side of the came ra viewing window =>
page 142,
fig. 157 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 d isappears before turning lane assist on
again.
• T he system was unable to detect bo undary lines over an extended
period of time due to road co nd it ions (such as snow-cove red lanes) .
Do not turn lane assist on aga in until the lines can be more easily
detected .

Signal lights are built into both outside mirrors~ fig. 159. The signal

lane and the signal light on the right outside mirror assists when
moving over into the right lane.
Th e 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 147. 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 s ignal and side assist detects a vehicle in
a notab le location, the corresponding signal on the outside mirror
flashes briefly and brightly several times. This is the
alert stage
signal ~

The system works at speeds faster tha n 19 mph (30 km/h) .
& 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 less 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
bloc ked by stic ke rs or othe r items.
[I) Tips
• Side ass ist automatica lly deac tivates if it detects that the radar
sensors are blocked=>
page 152. The indicator light on the button
goes out.
• Th e area on the bumper w he re the radar sensors are located must
c ons istent ly rema in free of snow, i ce, a nd he avy soiling so that s ide
assist can function properly. Follow the add itiona l notes on
=>page 1 5 2.

The detection~ page 146, fig. 161 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 151. •
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~

MMI settings
The basic brightness setting of the signal on the outside
mirror can be adjusted via the MMI.
Select: Function button [CAR]> Systems > Audi side assist >
Warning lamp: brightness.
- Rotate the control knob to adjust the displayed brightness
of the signal light on the outside mirrors.
The brightness of the signa l light for both the informational and alert
stages is automatically adjusted to ambient light conditions. In addi
t ion, you can adjust the
basic brightness separately, via the bright
ness function.
Whi le making the adjustment, the new brightness setting is
disp layed briefly . The brightness displayed is that of the informa
tional stage signal. The alert stage signal brightness is linked to the
informationa l stage signal brightness.
The inform ational stage signa l brightness should be adjusted so that
you notice the signal illumination when you look in the outside
mirror, but not when you look forward through the windshield.
In very dark or light surroundings, the automatic brightness setting
adjusts signa l light brightness to maximum or minimum intensity, as
needed. In circumstances such as these, you may not notice any
change in the brightness on the outs ide mirror when adjust ing the
basic brightness.
You may not not ice the change until lighting conditions are normal
again.
