The swerve assist can help you to steer the vehi-
cle around an obstacle detected in a critical area.
If you avoid an obstacle after the acute warning,
then the swerve assist assists you by applying
slight steering adjustment to correct your steer-
ing wheel angle as long as you are actively steer-
ing. Swerve assist is available at speeds between
approximately 20 mph (30 km/h) and 90 mph
(150 km/h).

ZA WARNING

When your vehicle is turning
The turn assist can assist you with a braking in-
tervention when starting to drive or when driving
slowly, to reduce the risk of your vehicle colliding
with an oncoming vehicle when you are making a
left turn). The braking intervention causes your
vehicle to stay in its lane. The function is only
available when the turn signal is turned on and at
speeds up to maximum of 6 mph (10 km/h).

Driver assistance

when the detected object is in the “blind
spot”, at the latest.
@ 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
If 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 exteri-
or mirror. The display remains dim in the infor-
mation stage so that you are not distracted while
looking forward.
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.
Depending on vehicle equipment, the display
may also provide a warning when the turn signal
is not activated: if driver assist systems detect
that your vehicle is about to leave a lane, the dis-
play will blink to warn you about objects classi-
fied as critical. You can also be warned with cor-
rective steering > page 137, Audi active lane as-
sist.
System limitations
The system uses the data from the radar sensors
at the rear corners of the vehicle > page 116,
fig. 107. 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 react 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 on the edge of your own lane
— Narrow lanes
— Curves
— High barriers on the side of the road
144

AN WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.
— The display may not appear on time when
vehicles are approaching or being passed
very quickly.
G) 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.
