Side assist funct ions at speeds above approxi­
mately 9 mph (15 km/h).
@ App roaching vehicles
In certain cases, a vehicle w ill be classified as
critical for a lane change even if it is still some ­
what far away . The faster a vehicle approaches,
the sooner the display in the exterior m irro r will
tu rn on.
@ Vehicles traveling with you
Vehicles traveling with you are indicated in the
exter ior mirror if they a re classified as cr it ical for
a la ne cha nge . A ll vehicles detected by side assist
are ind icated by the time they ente r you r "blind
spot" , at the la tes t.
@ Vehicles you are passing
If you s low ly pass a veh icle that s ide ass ist has
detected (the difference in speed between the
vehicle and you r vehicle is less than app roximate­
ly 9 mph ( 15 km/h)) , the disp lay in the exter ior
mir ror tur ns on as soon as the vehicle en te rs yo ur
blind spot .
The display w ill not tur n on if you quickly pass a
vehicle that side ass ist has detected (the diffe r­
ence in speed is grea ter than approximate ly 9
mph ( 15 km/h)) .
Functional limitations
The radar sensors are des igned to detect the left
and right adjacent lanes when the road lanes are
t h e norma l width. In some situa tions, the display
in the exte rior m irror may turn o n even though
t h ere is no veh icle located in the area that is criti-
ca l for a lane change. For example :
..,.
137

Ass is tanc e system s
-If the lanes are narrow or i f you are driving on
the edge of your lane. If this is the case, the
system may have detected a vehicle in another
lane that is
not adjacent to your current lane.
- If you are driving t hrough a curve. Side assist
may react to a vehicle that is one lane over
from the adjacent lane .
- If side assist reacts to other objects (such as
high or displaced guard rails).
- In poor weather conditions . The side assist
functions are limited.
Do not cove r the radar
sensors¢ fig . 141 with
stickers, deposits, bicycle whee ls or other ob ­
jects, beca use they wi ll impair the f unction . Do
not use side assist when towing a trailer. For in­
formation on cleaning,
see¢ page 354 .
A WARNING
-Always pay atte ntion to traffic and to the
area aro und your vehicle. Side assist cannot
r ep lace a dr ive r's attent ion. The dr ive r alone
is a lways responsible for lane c hanges and
s imi lar d riving maneuvers.
- In some situat ions, the system may not
func tion or its f un ct io n may be lim ited. Fo r
exa mple:
- If vehicles are approach ing or being le ft
beh ind very quickly. The display may not
tur n on in t ime.
- In poor weather conditions s uch as heavy
rain, snow or heavy mist.
- On very wide lanes, in tight curves, or i f
there is a rise in the road su rface. Vehicles
in the adjacent lane may not be detected
because they are outs ide of the sensor
range.
@ Note
The sensors can be displaced by impacts or
damage to the bumpe r, whee l housing and
underbody. Th is can impa ir the system. Have
an au thor ized A udi dealer or au tho rized Aud i
Serv ice Facility c heck their fu nction .

-Always look for traffic and check the area
around your vehicle by looking at it directly
as well. The parking system cannot replace
the driver's attent ion. The driver is always
responsible when enter ing or leaving a park­
ing space and during similar maneuvers.
-Please note that some surfaces, such as
clothing, are not detected by the system.
-Sensors and cameras have blind spots in
which people and objects cannot be detect­
ed . Be especially cautious of small children
and animals.
- Always pay attention to the area around the
vehicle -using the rearview mirror, too .
-The sensors can be displaced by impacts or
damage to the radiator gr ille, bumper,
wheel housing and the underbody . The park ­
ing system may be impa ired as a result.
Have an authorized Audi dealer or author­
ized Audi Serv ice Facility check their func­
tion.

such as chain link fences or powder snow
-If you continue driving closer to a low ob­
ject, it may disappear from the sensor
range . Note that you will no longer be
warned about th is obstacle.
-Keep enough distance from the curb to re­
duce the risk of damage to th e rims.
(I} Tips
-The system may provide a warning even
though there are no obstacles in the cover­
age area in some situations, such as:
-certa in road surfaces or when there is tall
grass
- external ultrasonic sources such as from clean ing vehicles
-in heavy rain, snow, or thick vehicle ex­
haust
-We recommend that you practice parking in
a traff ic -free location or parking lot to be ­
come fam iliar with the system . When doing
this , there shou ld be good light and weath­
er conditions .
-You can change the volume and pitch of the
signa ls as well as the display ¢
