Ass is t
When driving into a curve ¢ fig. 105 and out of a
curve, the adaptive cruise control may react to an
object in the neighbor ing lane and apply the
brakes. You can prevent that by pressing the ac
celerator pedal brief ly .
Stationary objects
App lies to: vehicles with Audi adaptive cruise contro l
Fig . 1 06 Example: ob ject c hangin g lanes and stat ionary
object
The adaptive cruise contro l system only reacts to
objects that are mov ing or that the system has
a lready detected as movi ng. For examp le, it can
react when a vehicle that has a lready been de
tected @turns or changes lanes, but adaptive
cru ise control does not react to a stat ionary vehi
cle @.

The distance between the two veh icles will
change in the instrument cluster display .
When approaching an object ahead, the adaptive
cruise contro l system brakes to match that speed
and then adjusts to the set distance.
If the object
ahead accelerates, adaptive cruise control will al
so accelerate up to the stored speed .
The higher the speed, the greater the distance
¢ ,&. .The
Distance 3 setting is recommended .
That is equal to the general recommendation of
"half the speed shown on the speedometer".
The distances provided are spec ified values . De

- Setting short distances to the traffic ahead
reduces the t ime and distance available to

Audi active Lane assist
(Lane departure assist)
Description
A ppl ies to: ve hicles w ith Audi active lane assist
Active lane ass ist detects lane marker lines with
in the l imits of the system us ing a camera in the
windshie ld. If you are approaching a detected
lane marker line and it appears likely t hat you
will leave the lane , the system will warn you with
correct ive steering . You can override t his steer ing
at any time. If you pass over a line, the steering
wheel will vibrate lightly . In order for this warn
ing vibration to occur, it must first be sw itched
on in the Infotainment system. Act ive lane assist
is ready for operation 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 h ighways and therefore only activates
at speeds above approximately 40 mph (65 km/
h) .
App lies to veh icles with side assist
If you activate a turn signa l when active lane as
sist is ready and it class ifies a lane change as crit
ical because of veh icles 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.
A pp lies to veh icles witho ut s ide ass ist
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 intent io nally.
102
App lies to: vehicles wi th adap tive cruise contro l
The corrective steering is targeted based on the
driving situation. In addition to the lane marker
li nes, the system can also take into account other
ob jects such as guard rails. If they are detected in
close prox imity to the ve hicle, active lane assist
helps prevent the vehicle from dr iving too close
to them . There is also pass ing ass istance. The
system does not provide any corrective steering if
i t detects that you are pass ing anothe r vehicle.
.&_ WARNING
- The system warns the drive r that the vehicle
is leaving the lane us ing correct ive steering.
The drive r is always responsible for keeping
the vehicle within the lane.
- The system can assist the dr iver in keeping
the vehicle in the lane, but it does not drive
by itself. A lways keep your hands on the
steer ing whee l.
- 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 . Cor rec
tive stee ring can only take place on the side
of the vehicle where lane marker lines are
detected.
- Other road structures or objects could poss i
bly be identified un intent ionally as lane
marker lines. As a result, corrective steering
may be unexpected o r may not occ ur.
- The camera view can be restricted, for ex
ample by vehicles driving ahead or by ra in,
snow, heavy spray or lig ht shining into the
camera. This can resul t in active lane ass ist
no t de tecting the lane marker lines or de
tect ing them in co rrectly .
- Unde r ce rtain cond it ions su ch as r uts in the
ro ad, a ban ke d roadway or crosswin ds, the
corrective s teer ing alone may not be enough
to keep the vehicle in the m iddle of the lane.
- For safety reasons, a ct ive lane assis t must
no t be use d when there are poor road and/
or weather conditions such as slippery
roads, fog, gravel, heavy rain, snow and the potential for hydrop laning. Using active lane
assist under these cond it ions may increase
the r isk of a crash.

movements, the driver's braking and accelera
tion, and as the road surface, vehicle speed and load. A sporty setting is generally used in vehicles
with adaptive air suspension sport*.
The vehicle ground clearance depends on the
mode selected and the speed. When you are in
the auto or dynamic mode, the highway setting is
activated when you drive above 75 mph (120 km/
h) for more than 30 seconds. The ground clear
ance is increased automatically if the speed
drops below 44 mph (70 km/h) for more than 120 seconds .
Steering
The power steering adapts. Indirect steering that
moves easily as in comfort mode is especially
suited to long drives on a highway. The dynamic
mode provides sporty, direct steering .
Applies to: vehicles with dynamic steering
The steering ratio changes based on vehicle
speed in order to maintain optimum steering ef
fort for the driver at all times . This sets the steer
ing to be less sensitive at higher speeds in order
to provide improved vehicle control. At reduced
speeds, steering is more direct in order to keep
the steering effort as minimal as possible when
the driver is maneuvering the vehicle. At low and
average speeds, dynamic steering* additionally
provides more responsive steering performance.
Sport differential*
As a component of the all wheel drive system
(quattro)
~ page 130, the sport differential dis
tributes the driving power to the rear axle de
pending on the situation. The distribution of
power varies from balanced (comfort) to sporty
(dynamic) depending on the selected mode. The
goal is a high level of agility and ability to accel
erate on curves. The vehicle is very responsive to
steering .
Cornering light*
The cornering light adapts the high beams to the
direction of the curve depending on the speed.
The pivoting action and the lighting also adapt to
the mode .
Assist
Adaptive cruise control*
The behavior when accelerating can be adjusted
from comfortable to sporty, depending on the
drive select mode. Adaptive cruise control also
responds to the driving behavior of the vehicle
ahead in a more conservative or sporty manner.
Engine sound*
The engine sound adapts to the current mode
and can be subtle to sporty.
(D Note
- Make sure there is enough clearance above
and below the vehicle when parking. The
height of the vehicle can change once it is
parked due to temperature fluctuations,
changes to the load conditions and changes
to the driving modes, which can affect clear
ance.
- When transporting the vehicle on a car car
rier, train, ship or by other means, only tie
the vehicle down at the running surface of
the tires, which is the outer circumference.
Securing the vehicle at the axle compo
nents, suspension struts or towing eyes is
not permitted because the pressure in the
air suspension struts can change during
transport. The vehicle may not be secured
sufficiently if this happens.
@ Tips
- In some models, the maximum vehicle
speed can only be reached in the auto and
dynamic modes.
- The S selector lever position automatically
engages if the dynamic mode is selected.
- In vehicles that have dynamic steering*, op
erating noise is heard when starting or stop
ping the engine. This does not indicate a
problem.
