Driver assistance
The display remains dim in the information stage
so that you are not distracted while looking for-
ward.
Side assist
Description
Applies to: vehicles with side assist
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.
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 154, Audi active lane assist/lane de-
parture warning.

General information
Side assist monitors the blind spot as well as the
traffic behind your vehicle and provides assis-
tance when you are changing lanes. If the system
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.
System limitations
The system uses the data from the radar sensors
at the rear corners of the vehicle ðpage 129,
fig. 104. 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
– 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.
– Observe the safety precautions and note the
limitations of the assist systems, sensors,
and cameras ðpage 127 to ðpage 130.
– The display may not appear on time when
vehicles are approaching or being passed
very quickly.
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 .
