Driver assistance
detects an object approaching and classifies it as
critical, the display 1 in the exterior mirror on
that side of the vehicle will turn on.
fig. 110. They are designed to detect the left and
right adjacent lanes when the road lanes are the
normal width. In some situations, the system
may respond to vehicles in your own lane or lanes
that are not directly adjacent to yours, or to ob-
jects on the side of the road. In this case, the dis-
play will turn on even though there is no vehicle
in the critical area. These situations may include:
Driving situations
The side assist warning is active at speeds above
approximately 9 mph (15 km/h) and can help in
situations such as the following:
– Your vehicle is being passed. The faster another
vehicle approaches from behind, the sooner the
display in the exterior mirror will turn on.
– There are vehicles traveling in the same direc-
tion as you in a lane adjacent to yours. The dis-
play in the exterior mirror will turn on when the
detected object is in the “blind spot”, at the lat-
est.
– Driving on the edge of your own lane
– Narrow lanes
– Curves
– High barriers on the side of the road
– Construction zones
WARNING
– Observe the safety precautions and note the
limitations of the assist systems, sensors,
and cameras ðpage 139 to ðpage 142.
– The display may not appear on time when
vehicles are approaching or being passed
very quickly.
– You are slowly passing another vehicle. If the
difference in speed between the two vehicles is
less than 9 mph (15 km/h), the display in the
exterior mirror will turn on.
Information stage
As long as you do not activate a turn signal, the
system will inform you about objects classified as
critical by turning on the display in the respective
exterior mirror 1 .
Tips
– If the window glass in the driver's door or
front passenger's door has been tinted, the
display in the exterior mirror may be incor-
rect.
The display remains dim in the information stage
so that you are not distracted while looking for-
ward.
– The system is not available when towing a
trailer. There is no guarantee the system
will turn off when using a retrofitted trailer
hitch. Do not use these functions when tow-
ing a trailer.
Warning stage
Once you activate a turn signal, the system will
inform you about objects classified as critical by
turning on the display in the respective exterior
mirror.
– The coverage areas of the sensors ðfig. 129
are schematic representations and do not
represent a true-to-scale image of the sen-
sor ranges.
If other driver assistance systems (depending on
vehicle equipment) detect that your vehicle is
about to leave the lane, the display will blink
even if the turn signal lever is not activated to
warn you about objects that are classified as criti-
cal. You can also be warned with corrective steer-
ing ðpage 165, Audi active lane assist/lane de-
parture warning.
– The system complies with United States FCC
regulations and ISED regulations
ðpage 322.
