_&. WARNING
-
Following other vehicles too closely in
creases the risk of a crash and serious per
sonal injury .
- Following other vehicles too closely, par
ticu larly at higher speeds increases the
risk of coll is ions and serious personal in
jury.
- Setting short distances to the traffic
ahead reduces the time and distance
available to bring your vehicle to a safe
stop and makes it even more necessary
to pay close attention to traffic .
- Always select a speed and distance to
traffic ahead that is safe and appropriate
under the prevailing traff ic, road, weath
er and lighting conditions.
- Never rely on the distance control fea
ture of ACC a lone to prevent rear-end col
lis ions. Always be prepared to b rake and
take evasive act io n to avoid co llisions
and other ac cident situations.
- Never allow the clos ing speed between
yo u a nd other vehicles to be so h igh that
the adaptive cruise control may not be
able to slow your vehicle safe ly . If clos
ing speed is too high, yo u m ust app ly the
brakes yourself to reduce the risk of a
rear-end crash.
- Always select a greater following dis
tance to the veh icle ahead on wet roads
than on dry roads.

¢ page 130, fig. 150.
Signal lights are bu ilt into both outside m ir
r ors ¢
fig. 148. The signal light on the left
outside mirror assists when moving over into
the left lane and the signal light on the r igh t
ou tside mirror assists when moving over in to
the right lane .
The s ignal light comes on to tell you that side
assis t has detec ted a vehicle on tha t side and
that t he position of this othe r vehicle should
be taken into account if yo u were to change
lanes . This is called the
informatio nal st age
sign al¢
page 131. The informat ional stage
Aud i side assist 129
signal is designed so that you notice it on ly
when you are looking in the outside mirror.
When yo u activate the turn signal and side as
s ist de tects a vehicle in a no table location, the
corresponding signal on the outside mi rror
flashes briefly and brightly several times. This
is the
a lert stage signal ¢ page 131 .

A WARNING
-Imp roper reliance on the side assist sys
tem can cause collis ions and serio us pe r
sonal injury:
- Never rely on ly on side assist when
changing lanes.
- Always check rear view mirrors to make
su re that it is safe to change lanes.
- Side assist canno t detect all veh icles un
de r all conditions- danger of accident!
- Side assist cannot detect vehicles in time
to a lert you w hen they app roac h from
behind at very hig h speed, or fall drop
back very qu ickly.
~
130 Audi side assist
-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 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 assist indicates
there are approaching vehicles, or vehi cles in your blind spot, only after your ve
hicle has reached a driving speed of at
least 19 mph (30 km/h).
- Side assist signal does not work around
tight corners (turning radius less than
328 feet, or 100 m).
- Side assist is no replacement for the driv
er's full attention. The driver alone is re
sponsible for lane changes and similar
driving maneuvers. Always keep an eye
on the direction you are traveling and the relevant area around the vehicle.
- To ensure that you do not adversely af
fect side assist, do not block the area on
the rear bumper where the radar sensors
are located with foreign objects (such as
stickers or bicycle racks).
- Make sure that the signal light on the
outside mirror is not blocked by stickers
or other items.
(Di Tips
- Side assist automatically deactivates if it
detects that the radar sensors are
blocked ¢
page 135. 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 soiling
so that side assist can function properly.
Follow the additional notes on
¢page 136.
-For vehicles with a factory installed tow
ing hitch* or a trailer hitch* that was in
stalled later according to factory specifi
cations, side assist is automatically deac- tivated
as soon as the electrical connec
tion to the trailer electrical socket is made
¢ page 135.
-For vehicles with a trailer hitch that was
not installed according to factory specifi
cations, switch off the side assist when
towing a trailer .
- Additional tinting on the front side win
dows can make it harder to see and cor
rectly understand the signal light on the
outside mirror.

Sensor detection area

-----··· .... ·--·--
@ / ,
--
ill b''T -
Fig. 150 Sc hematic illustration: Sensor detectio n area
The detection ¢ fig. 150 of the radar sensor
detection area is made up of:
-
- the approach area (light red area) (D, about
230 feet (70 m) behind the vehicle, and
- the "blind spot" (dark red area) @.
The radar sensors cover the adjacent left and
right lanes. Other lanes are
not covered by the
radar sensors.
(D Tips
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 travel lane, it is possible that vehicles
will be detected that are
not in the lane
next to the lane you are using
¢page 135.
Operation
Applies to vehicles: with side assist
Side assist compares the distance and differ
ence in speed of detected vehicles with the
speed of your vehicle . Whenever the differ
ence in speed and d istance is registered as no
table if you were to change lanes, a signal l ight appea rs on the respective mirror.
The signal can light up if you are passed by a
vehicle or if you are pass ing another vehicle.
If you pass another vehicle s lowly (difference
in speed less than 9 mph, or 15 km/h), the
signal light will come on as soon as the other
vehicle is in your blind spot and is detected by
side assist . When the difference in speed is
g reater, the signal light will not come on.
Informational and alert stage signals
Applies to vehicles: with side assist
Side assist has two signal stages:
- the informational stage signal, and
- the alert stage signal.
Side assist he lps you by using the appropriate
signal stage, depending on whether or not
you have activated the turn signal, and thus have indicated that you are or are not chang
in g lanes .
Informational stage signal
As long as you have not activated the turn sig
nal, side assist informs you of detected vehi
cles that are registered as being in a notable locat ion if you were to change lanes. Whenev
er the detected vehicle's difference i n speed
and distance is registered by side assist as no
table, the signal light on the respective m irror
produces muted illuminat ion.
The br ightness of the informat ional stage sig
nal is designed not to be as intense, so that it
does not interfere with your view of the road
when yo u are driving and have no intention of
changing lanes. When you look i n the outside
Aud i side assist 131
mirror, you can clearly see the informational
stage signal.
Alert stage signal
When you activate the turn signal, and s ide
ass ist has detected a vehicle in a notable loca
t ion on that part icular s ide, the signa l 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
¢ A in Safety tips on page 136 .
@ Tips
The brightness of the signal light on the
outside mirrors can be adjusted with the
MMI ¢page 134.

@ Informational stage signal lights up
A fast approaching veh icle - in the left-hand
l ane for examp le - was detected by the sen
sors . Although this vehicle is sti ll far away, it
should be taken into account if you were to
change lanes, due to the considerable differ
ence in speed. The informational stage signal
on the outside m irror lights up
c::;, page 131.
@ Alert stage signal flashes
If you activate your turn signal in driving sit
uation @, the signal briefly f lashes repeated
ly. Side ass ist is alerting you to a veh icle that
you may not have noticed.
@ Tips
- The faster a vehicle approaches from the
rear, the sooner the signal on the outside
mirror lights up. Side assist will signa l,
at the latest, when a detected vehicle en
ters your "blind spot" .
- When vehicles approach very quickly,
changing lanes can be dangerous even if
the signal on the outside mirror does not
light up.
