Side assist uses radar sensors (not visible on outside)=> fig. 144 to
help the driver check blind spots, and see what is happening in
traff ic behind the vehicle=>

the left lane and the signal light on the right outside mirror assists
when moving over into the right lane.
The signa l ligh t comes on to te ll you that s ide assist has detected a
vehicle on that side and tha t the position of this o ther vehicle
should be taken into account i f you we re to change lanes . This is
called the
inform ati onal sta ge sign al=> page 137 . The informational
stage signal is designed so that you notice it only when you are
looking in the outside mirror .
When you activate th e turn signal and side assist detects a vehicle
in a notable location, the corresponding signa l on the outside
mirror flashes briefly and brightly sev eral tim es. This is the

& 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.
0 Note
• T o ensure t hat you do n ot adve rsely affect side ass is t, do not
block the area on the rear b umper whe re the radar sensors a re
lo cate d with for eign objects (suc h as st ic ke rs or b icycle racks).
• M ake s ure that the s igna l lig ht on the outside mi rror is not
blocked by st ickers o r other it em s.
[ i ] Tips
• Side ass ist auto matical ly deact ivates if it det ects that t he radar
sensors are blocked => page

Sensor detection area
Fi g. 14 7 Sc hem atic
illu stra tion: Senso r
d etec tion area
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
t o the lane you are using=>
page 142. •
Controls and equip ­
ment

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 .•

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. .,
I • •

• ..__A_ u_ d_ i _s _i_d _e_ a_ s_ s _ is_ t __________________________________________________ _
When you look in the outside mirror, you can clearly see the infor­
mational stage signal.
Alert stage signal
When you activate the turn signal, and side assist has detected a
vehicl e 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 carefully check
traffic to the rear in the outside mirror and over your shoulder, so
that you can safely complete the lane change=>

Adjusting sign al
brigh tness
- Select: Function button [CARI> Audi side assist
=> fig. 152.
- Rotate the cont ro l knob to adjust the displayed bright-
ness of the signal light on the outside mirrors .
The brightness of the signal light for both the informationa l and
alert stages is automatica lly adjusted to ambient light conditions. In
addition, you can adjust the
basic brightness separately, via the
brightness function
=> fig . 152.
While making the adjustment, the new brightness setting is
displayed briefly. The brightness displayed is that of the informa ­
tional stage signal. The alert stage signa l brightness is linked to the
informational stage signal brightness .
Controls and equip ­
ment
The informational stage signal brightness should be adjusted so
that you notice the signa l 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 signal ligh t brightness to maximum or minimum intensity,
as needed . In circumstances such as these, you may not notice any
change in the brigh tness on the outside mirror when adjusting the
basic brightness.
You may not notice the change until lighting conditions are normal
again.
[ i ] Tips
• Side assist is not active when the basic brightness is adjusted.
The signal light comes on briefly to help you make the adjustment .
• Your settings are automatically stored and assigned to the
remote control key being used.•

General information
Side assist has limits and cannot detect vehicles under a ll road and
weather conditions . Please remember system limitat ions and never
re ly on the system, especially when:
• driving through curves=>
page 141,
• lanes are of different widths=> page 142. •
Applies to veh ic les : with s ide ass ist
When driving through curves
Side assist cannot detect vehic les in curves with a turning radius of
less than 328 feet (100 ml. .,,
I • •

• .___A_ u_ d_ i_s_ i_ d _e_ a_ s_ s_is _ t __________________________________________________ _
When driving through a curve, it is possible that side assist may
register a vehicle two lanes over, and the signal on the outside
mirror will light up.•
Applies to veh icles: with side assist
Lane width
Fig. 153 Lanes of a
normal width are in
detection area
Fig. 154 Narrow lanes :
Side assist may detect
vehicles two lanes
away
Side assist's detection area is designed to cover lanes of standard
width to the left and right of your travel lane, depending on whether
you drive in the center of your lane or closer to the edge.
If you drive in narrow lanes, side assist's detection area may also
include other lanes -especially if you tend to drive on the edge of
your lane=> fig. 154. Under these conditions, vehicles can also be detected that are two
lanes away, and side assist then could switch
between the informational and warning stage signals.
When driving in very wide lanes, vehicles in the adjacent lane may
not be detected because they are not inside the detection area. •
Notes
Applies to vehicles: with side assist
Messages in instrument cluster display
If side assist turns off automatically, the indicator light on the
button will go out and you will see a message in the instrument
cluster display:
Audi side assist not available : sensors possibly blocked
The side assist sensors are built into the rear bumper on the left and
right (not visible on the outside)=? page 135, fig, 144. To ensure that
you do not adversely affect the way side assist functions, foreign
objects (such as stickers or bicycle racks) should not be attached to
the area on the rear bumper where the sensors are located. If side
assist functions are adversely affected, you will see this message in
the instrument cluster display. Remove anything that may be
blocking the sensors.
I f no vehicle is detected for a longer period of time while driving,
side assist will also switch off automatically.
