Audi active lane assist
Applies to: vehicles with Audi active lane assist
Active lane assist (lane departure warning) de-
tects lane marker lines within the limits of the
system using a camera in the windshield. If you
are approaching a detected lane marker line and
it appears likely that you will leave the lane, the
system will warn you with corrective steering.
You can override this steering at any time. If you
pass over a line, the steering wheel will vibrate
lightly. In order for this warning vibration to oc-
cur, it must first be switched on in the Infotain-
ment system. Active lane assist is ready for oper-
ation when the lane marker line is detected on at
least one side of the vehicle.
The system is designed for driving on express-
ways and highways and therefore only activates
at speeds above approximately 40 mph (65
km/h).
Applies to: vehicles with Audi side assist
If you activate a turn signal when active lane as-
sist is ready and it classifies a lane change as crit-
ical because of vehicles traveling alongside you or
approaching you, there will be noticeable correc-
tive steering shortly before you leave the lane.
This will attempt to keep your vehicle in the lane.
Applies to: vehicles without Audi side assist
The system will not warn you before crossing a
lane marker line if you have activated the turn >

signal. In this case, it assumes that you are
changing lanes intentionally.

Z\ WARNING
— The system warns the driver that the vehicle
is leaving the lane using corrective steering.
The driver is always responsible for keeping
the vehicle within the lane.
— The system can help you keep the vehicle in
the lane, but it does not drive by itself. Al-
ways keep your hands on the steering wheel.
— Corrective steering may not occur in certain
situations, such as during heavy braking.
— There may be cases where the camera does
not recognize all lane marker lines. Correc-
tive steering can only take place on the side
of the vehicle where lane marker lines are
detected.
— Other road structures or objects could possi-
bly be identified unintentionally as lane
marker lines. As a result, corrective steering
may be unexpected or may not occur.
— The camera view can be restricted, for exam-
ple by vehicles driving ahead or by rain,
snow, heavy spray light shining into the
camera or by dirt on the window. This can
result in active lane assist not detecting the
lane marker lines or detecting them incor-
rectly.
— Under certain conditions such as ruts in the
road, an inclined roadway or crosswinds, the
corrective steering alone may not be enough
to keep the vehicle in the middle of the lane.
— For safety reasons, active lane assist must
not be used when there are poor road and/or
weather conditions such as slippery roads,
fog, gravel, heavy rain, snow and the poten-
tial for hydroplaning. Using active lane as-
sist under these conditions may increase the
risk of a crash.

If the system is switched on but is not ready to
provide warnings, one of the following could be
the cause:
— There is no lane marker line
— The relevant lane marker lines are not detected
(for example, markings in a construction zone
or because they are obstructed by snow, dirt,
water or lighting)
— The vehicle speed is below the activation speed
of approximately 40 mph (65 km/h)
— The lane is too narrow or too wide
— The curve is too narrow
— The driver's hands are not on the steering
wheel

detected and classified as critical. The display in
the mirror turns on, but is dim.
The display remains dim in the information stage
so that your view toward the front is not distur-
bed.
Warning stage
If the display in a mirror blinks brightly when you
activate a turn signal, side assist is warning you
about detected vehicles that it has classified as
critical. If this happens, check traffic by glancing
in the exterior mirrors and over your shoulder
=> A\ in General information on page 133.
Applies to: vehicles with Audi active lane assist
The display in the mirror can also blink if you
have not activated a turn signal: if you are ap-
proaching a detected lane marker line and it ap-
pears you will be leaving the lane, side assist will
warn you about detected vehicles that it has clas-
sified as critical.

Fig. 127 Rear of the vehicle: position of the sensors
Side assist functions at speeds above approxi-
mately 9 mph (15 km/h).
@ Approaching vehicles
In certain cases, a vehicle will be classified as
critical for a lane change even if it is still some-
what far away. The faster a vehicle approaches,
the sooner the display in the outside mirror will
turn on.
@ Vehicles traveling with you
Vehicles traveling with you are indicated in the
exterior mirror if they are classified as critical for
a lane change. All vehicles detected by side assist
are indicated by the time they enter your “blind
spot”,
at the latest.
@ Vehicles you are passing
If you slowly pass a vehicle that side assist has
detected (the difference in speed between the ve-
hicle and your vehicle is less than approximately
9 mph (15 km/h)), the display in the exterior mir-
ror turns on as soon as the vehicle enters your
blind spot.
The display will not turn on if you quickly pass a
vehicle that side assist has detected (the differ-
ence in speed is greater than approximately 9
mph (15 km/h)).
Functional limitations
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
in the exterior mirror may turn on even though
there is no vehicle located in the area that is criti-
cal for a lane change. For example:

stage.
The brightness of the warning stage is linked to
the brightness in the information stage and is ad-
justed along with the information stage.
The display brightness adjusts automatically to
the brightness of the surroundings, both in the
information and in the warning stage. In very
dark or very bright surroundings, the automatic
adjustment will set the display to the minimum
or maximum level. In such cases, you may notice
no change when adjusting the brightness, or the
change may only be noticeable once the sur-
roundings change.

Parking space search
Applies to: vehicles with park assist

Fig. 142 Infotainment: notification to continue driving in
reverse (example: when parallel parking)
Searching for parking spaces
> Drive forward to the row of parking spaces ata
low speed. For the best parking results, the ve-
hicle should be approximately 3 feet (1 m) from
the row of parking spaces.
> The parking space search is first done on one
side of the lane. To switch the side for the park-
ing space search, activate the turn signal for
that side.
Selecting the parking space
> If the system finds a parking space that could
be suitable for the vehicle length and width, it
will be displayed > fig. 141. The system auto-
matically suggests a parking option.
> Make sure that the parking space is suitable for
your vehicle.
> To switch between parallel (@), forward perpen-
dicular @) or reverse perpendicular © parking,
turn the control knob to the desired mode. Only
the parking options that are currently possible
are suggested.
> Drive forward until the instructions for auto-
matic parking appear in the instrument cluster
> /\ in Description on page 141, >©@ in De-
scription on page 141. As soon as the vehicle
142
has reached the correct position, a P appears in
the display over the selected parking space.
> Keep the vehicle as parallel as possible to the
parked vehicles or to the side of the road.
> If you would like to park using the system, fol-
low the instructions in the instrument cluster.
Park assist only displays parking spaces that are
suitable for the length and width of the vehicle.
@) Note
— Parking spaces classified as suitable by the
system may have been detected incorrectly.
The driver must decide if the parking space
displayed is suitable for the vehicle.
— Certain conditions near the parking space
may cause the parking process to fail, such
as if the parking space is near trees or posts,
or if the ground is covered, for example,
with gravel, snow, or ice.
G) Tips
— You can select a space from all of the park-
ing options found. The possible parking
space will be displayed until you are too far
away from it.
— If you did not drive past a suitable parking
space too quickly, the system can also be ac-
tivated afterwards by pressing the Pe button
and activating the turn signal.
— If suitable parking spaces are available on
both sides of the road at the same time
(such as on a one-way street), the direction
of the turn signal can also be changed in or-
der to use park assist.
— Park assist will switch off if your speed ex-
ceeds approximately 30 mph (50 km/h).
Starting the parking process
Applies to: vehicles with park assist
The responsibility is with the driver when park-
ing.
Requirement: a suitable parking space must be
found and selected > page 142. The vehicle must
