2021 AUDI E-TRON light

Driver assistance

— Control by the system depends on which
adaptive cruise assist driving program is set
or on the selected Audi drive select* mode.
— After switching on the ignition and first
driving onto a freeway or similar road with-
out a speed limit, the system will regulate
the speed to 80 mph (130 km/h). Then
the system adjusts to the last speed set by
the driver.
— There is no adaptation to speed limits when
driving through highway interchanges and
when driving on or off the expressway.
— The system can fail to provide control or the
control may be faulty if the values from the
camera-based traffic sign recognition* are
incorrect or the navigation system map data
is outdated.
— When route guidance is switched on, the
system adapts to the route provided by the
navigation system. Driving without route
guidance or leaving a route can result in
faulty control.

If you adjust the speed, you must also change the
time gap to the vehicle driving ahead. The higher
the speed, the greater the distance that is need-
ed.

The newly-set distance will be shown briefly, for
example with the a indicator light. In the Driv-
er assistance display, a graphic display is shown
instead of the indicator lights > page 145,
fig. 101. The display matches the functions of
the indicator lights.
When approaching a vehicle driving ahead, the
adaptive cruise assist brakes to the set speed and
then maintains the set distance. If the vehicle
driving ahead accelerates, then the adaptive
cruise assist will also accelerate up to the speed
that you have set.
The following distances can be set:

Meaning

The time between is approximately 1
second. This setting corresponds toa
distance of approximately 92 feet (28
m) when traveling at 62 mph (100
km/h).
The time between is approximately 1.3
seconds. This setting corresponds toa
distance of approximately 118 feet
(100 m) when traveling at 62 mph
(36 m/h).
The time between is approximately 1.8
seconds. This setting meets the general
recommendation of “half the speed
shown on the speedometer”. This cor-
responds to a distance of approximate-
ly 164 feet (50 m) when traveling at
62 mph (100 km/h).
The time between is approximately 2.4
seconds. This setting corresponds toa
distance of approximately 219 feet
(100 m) when traveling at 62 mph
(67 m/h).
The time between is approximately 3.6
seconds. This setting corresponds to a
distance of approximately 328 feet
(100 m) when traveling at 62 mph
(100 m/h).

approaching from behind and provide a warning
when you are changing lanes and turning. The
system uses the data from the radar sensors at
the rear corners of the vehicle.
The side assist is active at walking speeds and
higher. If an object that is classified as critical is
approaching, the display in the exterior mirror @)
on the corresponding side of the vehicle will light
up.
Driving situations
The system can provide warnings about the fol-
lowing risks:
@ Approaching vehicles: a vehicle may be clas-
sified as critical in some cases, even if it is
farther away. The faster a vehicle ap-
proaches, the sooner the display will turn on.
@® Vehicles traveling in the same direction: the
display will turn on if vehicles traveling in the
same direction as your vehicle are classified
as critical. The side assist warns you of all de-
tected vehicles when they are in the “blind
spot” or before they reach that point.
@® Vehicles you are passing: the display only
turns on if you slowly pass a detected vehicle
(difference in speed between the two vehicles
is less than 9 mph (15 km/h)). There is no
display if you pass a vehicle more quickly.
Information stage
At the information level, the side assist informs
you of detected objects that are classified as criti-
cal. This is even possible when your vehicle is sta-
tionary and the turn signal is turned on, so that
the system can also assist you when turning.
From speeds of approximately 6 mph (10 km/h)
and higher, the system will warn you of detected
objects that are classified as critical, even if the
turn signal is not turned on.
The display remains dim in the information stage
so that you are not distracted while looking for-
ward.
Warning stage
If you activate a turn signal and the display flash-
es, side assist is warning about objects that have
been classified as critical.
Depending on the vehicle equipment and other
driver assistance systems, the display may also
flash if you have not activated a turn signal. If
you are approaching a detected lane marker line
and it appears you will be leaving the lane, the
display will warn you about detected vehicles
that are classified as critical. You can also be
warned with corrective steering > page 155,
Lane departure warning.
Detection range
The radar sensors are designed to detect the left
and right adjacent lanes when the road lanes are
the normal width. In some situations, the display
may turn on even though there is no vehicle lo-
cated in the area that is critical for a lane change.
For example:
— If the lanes are narrow or if you are driving 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 current lane.
— If you are driving through a curve. Side assist
may react to a vehicle that is in the same lane
or one lane over from the adjacent lane.
— If side assist reacts to other objects (such as
roadside structures like guard rails).

ZA WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 129.
— The display may not appear on time when
vehicles are approaching or being passed
very quickly.
@ 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:

— These systems are not available in trailer
towing mode. There is no guarantee the sys-
tems will switch off when using a retrofitted
trailer hitch. Do not use these functions
when towing a trailer.
