T he system works at speeds faster than 19 mph (30 km/h) .
& WARNING
• Improper reliance on the side assist system can cause colli­
sions and seriou s per sonal injury:
- Never rely only on side assist when changing lanes .
- Always check rear view mirrors to make sure that it is safe to c hange lanes.
• Side assist cannot detect all vehicles under all conditions­
danger of accident!
• Side assist cannot detect vehicles in time to alert you when
they approach from behind at very high speed , or fall 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 veh icles 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 assi st indicates there are approaching
vehicles, or vehicles in your bl ind spot , only after your vehicle has
reached a driving speed of at lea st 19 mph (30 km /h).
• S ide assist signal does not work around tight corners (turning
radiu s less than 328 feet or 100 m ).
• Side assist is no replacement for the driver's full attention . The
d river alone is responsible for lane changes and similar driv ing
maneuvers. Always keep an eye on the d ire ction you are travel ing
and the relevant area around the vehicle .

Sensor detection area
Fig. 176 Sc hem ati c
illu str ati on : Sens or
d etec tio n area
The detection ~ fig. 176 of the radar sensor detection area is made
up of:
• the approach area !light green area)
0, about 230 feet (70 ml
behind the veh icle, 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 travel lane, it is
possible that vehicles will be detected that are
not in the lane next
to the lane you are using~
page 163. •
Applies to vehicl es: with side assist
Operation
Side ass ist 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 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 slowly (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 greater, the signa l light will not come on .•
Applies to vehic les : w ith side assist
Informational and alert stage signals
Side assist has two signal stages:
• the informational stage signal, and
• the alert stage signal.
Side assist helps you by using the appropriate signa l stage,
depend ing on whether or not you have act ivated the turn signal,
and thus have indicated that you are or are not changing lanes.
In fo rm ati onal stag e 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 luminatio n.
The brightness of the informationa l stage signal 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. .,,,

___________________________________________________ A_u_ d_i_ s_ id_e_ a_ s_s _i_s _t _ __.1!111
When you look in the outside mirror, you can clea rly see the infor ­
mational s tage signal.
Ale rt sta ge signal
When you ac tivate the turn signal, and side assist has detected a
vehic le in a notab le location on that particu lar sid e, the signal light
on this side mirror flashes brightly. The repea ted brief and bright
flash ing of the aler t stage signa l reminds you to carefully check
t raffic to the rear in the outside mirror and over your shoulder, so
that you can safely complete the lane change=>

G) Signal on outside mirror does not light up
A vehicle approaching slowly -in the left -hand lane for example -
was detected by the sensors. Because of the small difference in speed and the considerable distance from your vehicle, the signal
on
the outside mirror will not light up
~ & in "Safety tips" on
page 164.
© Informational stage signal lights up
The distance between your vehicle and that of the slowly
approaching vehicle has narrowed. The informational stage signal
on the outside mi rror lights up.
As soon as the difference in speed and distance is registered as notable if you were to change lanes, a signal on the mirror lights up .
Side assis t will signal a t the latest when a detected vehicle enters
your "blind spot".

General information
Side assist has lim its and cannot detect vehic les under all road and
weather conditions. P lease remember system limitations and
never
rely on the system, especially when:
• driving through curves=>
page 763,
• lanes are of different widths=> page 163. •
Applie s to vehicles: with side ass ist
When dr iving through curves
Side assist cannot detect vehicles in curves with a turning radius of
less than 328 feet (100 m).
When driving through a curve , it is possible that side assist may
register a vehicle two lanes
over, and the signal on the outside
m irror will ligh t up .•

Side assist's detection area is designed to cover lanes of standard
width to the le ft and right o f your trave l lane, depending on whethe r
you drive in the center of your lane or c loser to the edge.
If you drive in narrow lanes, side assist's detection area may also
inc lude other lanes -especially if you tend to dr ive on the edge o f
your lane=> fig . 184. Under these conditions, vehicles can also be
de tected tha t are two lanes away, and s ide assist then could switch
between the informational and warning stage signa ls.
When d riving in
very wide lanes, vehicles in the adjacent lane may
not be detected because they are not inside the detection area. •

-Press the sw itch PJJJ! in the cente r console ~ page 173,
fig . 194 t o activate the A udi pa rking system m anually .
Activation of the acoustic parking system is confirmed by
a brief acknowledgement sound . The indicator lig ht in
the switch lights up.
D ea ctivation
If you drive forwards faster tha n approx. 6 mph (10 km/h),
or
- if you switch the ign ition off, the entire acoustic parking
assist is automatically deactivated, or
- you can press the sw itch
P111! i n the center console
=> page 173, fig. 194 to deact ivate the Audi parking
system. The indicator light in the switch goes out.
You have to turn on the acoustic parking assist m anuall y if you wish
to park the vehicle forwards or if you w ish to approach an obstacle
forwards and want a distance warning .

Distance warning is given by chimes which are generated by a
signal generator . The volume and the pitch of the chimes can be
adjusted in the MMI => page
183.
Mute
In the case of vehic les with automa tic transmission, an acoustic
distance warning is discontinued when the transmission selector l
ever is moved to the P position. However, the system remains
active . As soo n as the selector lever is moved from the
P posi tion
and the vehicle approaches an obstacle, the acoustic distance
warning resumes .
Dri ving fo rward/ba ckvv ard
Distance warning when driving forward/backward is based o n
detection of an obstacle in the range of the parking assist . As the
distance dec reases, the time interval between the audible tones
becomes shorter.
When the distance is less than approx . 1 ft (0.30 m), the tone
becomes continuous. At this point you shou ld s top backing up or
driving forward .
If the distance to an obstac le remains the same, the vo lume of the
distance warning is gradually reduced after about
4 seconds (does
not app ly to the zone for the cont inuous tone). If you sta rt to
approach the detected obstacle again, the distance warning will
sound at the normal volume again .
P a rk ing
When you selec t ano ther gear when parki ng (e .g . reverse/forward),
the warning tones are temporarily suppressed, but the visual display remains on the MMI display . If you start approaching a
detected obstacle again, the distance warning wi ll sound at the
normal vo lume again .
Visual disp lay
T he segments on the MMI display indicate a change in the distance
between the vehicle and an obstacle . The number of segments
displayed depends on the obstacles in front of or behind the
vehic le. The c loser the vehic le comes to the obstacle, the closer the
segments approach the vehic le => page
173 , fig. 195. When the
segment before last is disp layed, the veh icle has reached the colli­
sion zone. At this point you should stop backing up or driving
forward =>
