Sid e assist (lane change ass ist) helps you mon itor
your blind spot and traffic behind yo ur vehicle .
Within the limits of the system, it warns you
about vehicles that are com ing closer or that are
traveling with you within sensor range
(D
¢ fig. 144. If a lane change is classified as criti­
cal, the display @in the exterior mirror turns on

The display in the left exterior mirror provides as­
s istance when making a lane change to the left,
while the display in the right exterio r mir ror pro­
vides assistan ce when making a lane change to
the righ t.
Information stage
As long as you do not activate the tu rn signal,
side assist
informs yo u about vehicles that are
detected and classified as critical. The display in
the mirror turns on, but is dim .
The display remains dim in the information stage
so that your view toward the front is not distur­
bed.
Warning stage
If the display in a mirror blinks brightly when you
activate a turn signal, side assist is
warning you
about detected vehicles that it has classified as
critical. If this happens, check traff ic by glancing
in the exterior m irrors and over your shoulder
¢ & in General information on page 141 .
Applies to: vehicles with Audi act ive lane ass ist

General information
App lies to: ve hicles w ith Audi side assist
@
Fig. 146 Driving s it u ations
Fig. 147 Rear of the veh icle: pos it ion of the sensors
Side assist functions at speeds above approxi­
mately 9 mph (15 km/h) .
@Approaching vehicles
In certain cases, a vehicle will be classified as
critical for a lane change even i f it is still some ­
what far away. The faster a vehicle approaches,
140
the sooner the display in the exterior mirror will
turn on .
@Vehicles traveling with you
Vehicles traveling with you are indicated in the
exter ior mirror if they are classified as critical for
a lan e change . All vehicles detected by side assist
are indicated by the time they enter your "blind
spot", at the latest .
@ Vehicles you are passing
If you slow ly pass a vehi cle that side assist has
detected (the differe nce in speed between the
vehicle and your vehicle is less than approximate­
l y 9 mph (15 km/h)), the disp lay in the exterior
mirror turns on as soon as the vehicle enters your
blind spot.
The display wi ll not turn on if you quickly pass a
vehicle that side assist has detected (the differ­ ence in speed is greater than approximate ly 9
mph (15 km/h)) .
Functional limitations
The radar sensors are designed to detect the lef t
and right adjacent lanes when the road lanes are
the normal width . In some situations, the display
in the exterior m irror may turn on even though
there is no vehicle located in the area that is criti­
ca l for a lane change. For example:
- If the lanes are narrow or if your
are dr ivin g 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 cur rent lane.
- If you are driving through a curve. Side ass ist
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 ra ils).
- In poor weather conditions. The side ass ist
functions are limited.
Do not cover the radar
sensors ¢ fig. 147 with
stickers, deposits, bicycle wheels or other ob ­
j ects, because they will impair the function. Do
not use s ide assist when towing a trai ler. For in-
format ion on cleaning,
see ¢ page 347. .,..

CXl CXl .... N r--­N .... 0 N > 00
A WARNING 1=
- Always pay attention to traffic and to the
area around your vehicle. Side assist cannot
replace a dr iver's attention. The dr iver alone
is always responsible for lane changes and
similar driving maneuvers.
- In some situat ions, the system may not
function or its funct io n may be limited. For
example:
- If vehicles are approaching or being left
behind very quickly. The display may not
turn on in time.
- In poor weather conditions such as heavy
rain, snow or heavy mist.
- On very wide lanes, in tight curves, or if
there is a rise in the road surface. Vehicles
in the adjacent lane may not be detected
because they are outside of the sensor
range.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. Th is can impa ir the system. Have
an authorized Audi dealer or authorized Audi
Serv ice Facility check their function .

Parking systems
General information
A ppl ies to: ve hicles w ith parking system plus/rearview cam ­
era
Depending on your vehicle's equipment , various
parking aids will help you when parking and ma­
neuvering.
The
parking system plus assists you when park­
ing by audibly and visually indicating objects de­
tected
in front of and behind the vehicle
¢page 147.
The rearview camera shows the area behind the
vehicle in the Infotainment system display. This display assists you when you are cross or parallel parking. The parking system plus functions are
also available ¢
page 148.
A WARNING
-
-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 attention. The driver is always
responsible when entering 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 -us ing the rearview mirror, too.
-The sensors can be displaced by impacts or
damage to the radiator grille, bumper,
wheel housing and the underbody . The park­
ing system may be impaired as a result.
Have an authorized Audi dealer or author­
ized Audi Service Facility check their func­
tion .
(D Note
-Some objects are not detected or displayed
by the system under certain circumstances:
-objects such as barrier chains, trailer draw
bars, vertical poles or fences
146
-objects above the sensors such as wall ex­
tensions
-objects with certain surfaces or structures
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 this obstacle.
-Keep enough distance from the curb to re­
duce the risk of damage to the rims.
(D Tips
-T he system may provide a warning even
though there are no obstacles in the cover­ age area in some situations, such as:
-certain road surfaces or when there is tall
grass .
-external ultrasonic sources such as from
cleaning vehicles.
-in heavy rain, snow, or thick vehicle ex­
haust.
-We recommend that you practice parking in
a traffic-free location or parking lot to be­
come familiar 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
signals as well as the display¢
page 150.
-What appears in the infotainment display is
somewhat time-delayed .
-The sensors must be kept clean and free of
snow and ice for the parking aid to operate .
