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,

& 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 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 ¢

the d isplay appear closer or farthe r away:
- For objects that do not touch the ground,
such as the bumper of a parked vehicle, a
trailer hitch or the rear of a truck . Do not
use the orientation lines in this case .
- If driven from a level surface onto an in­
cline, o r a downward slope.
- If driven toward protrud ing objects.
- If the veh icle is carry ing too much load in
the rear.
