Assistance systems
-With stationary objects ¢ page 97.
A WARNING
Always pay attention to traffic when adaptive
cruise control is switched on and braking
guard is active. As the driver, you are still re
sponsible for starting and for maintaining
speed and distance to other objects. Braking
guard is used to assist you . The driver must
always take action to avoid a collision. The
driver is always responsible for braking at the
correct time.
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydroplan
ing). Using the system under these condi
tions increases the risk of an accident.
- Switch adaptive cruise control off tempora
rily when driving in turning lanes, on ex
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the stored speed when in these situations .
- The adaptive cruise control system will not
brake by itself if you put your foot on the ac
celerator pedal. Doing so can override the
speed and distance regulation.
- When approaching stationary objects such
as stopped traffic, adaptive cruise control
will not respond and braking guard will have limited function.
- The adaptive cruise control system and
braking guard do not react to people, ani
mals, objects crossing the road or oncoming
objects.
- The function of the radar sensors can be af
fected by reflective objects such as guard
rails, the entrance to a tunnel, heavy rain or
ice.
A WARNING
- Improper use of adaptive cruise control can
cause collisions, other accidents and serious
personal injury.
- Never let the comfort and convenience that
adaptive cruise control and braking guard
96
offer distract you from the need to be alert
to traffic conditions and the need to remain
in full control of your vehicle at all times,
- Always remember that the adaptive cruise
control and braking guard have limits -they
will not slow the vehicle down or maintain the set distance when you drive towards an
obstacle or something on or near the road
that is not moving, such as vehicles stopped
in a traffic jam, a stalled or disabled vehicle.
If registered by the radar sensors, vehicles
or obstacles that are not moving can trigger
a collision warning and if confirmed by the
video camera, an acute collision warning.
- Never follow a vehicle so closely that you
cannot stop your vehicle safely. The adap
tive cruise control cannot slow or brake the
vehicle safely when you follow another vehi cle too closely. Always remember that the
automatic braking function cannot bring the
vehicle to a sudden or emergency stop un
der these conditions .
- To prevent unintended operation, always
switch ACC off when it is not being used .
@ Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. That could affect the adaptive
cruise control system and braking guard .
Have an authorized Audi dealer or authorized
Audi Service Facility check their function.

In curves
Applies to: ve hicles with Audi adaptive cruise co ntro l
Fig. 105 Examp le: d riving into a curve
When driving into a curve <=> fig. 105 and out of a
curve, the adaptive cru ise control may react to an
object in the ne ighboring lane and apply the
b rakes. You can prevent that by pressing the ac
celerator pedal b riefly.

The adaptive cruise contro l system only reacts to
objects that are mov ing or that t he system has
already detected as moving. For example, it can react when a vehicle that has already been de
tected @turns or changes lanes, but adapt ive
cru ise control does not react to a stat ionary vehi

Audi active lane assist
(lane departure assist)
Description
Applies to: vehicles with Audi active lane assist
Active lane ass ist detects lane marker lines with
in the limits of the system us ing a came ra in t he
w indsh ie ld. If you are app roaching a de tected
l ane marker line and it appea rs likely t hat you
will leave the lane, the system wi ll warn you with
corrective steering. Yo u can override t his steering
at any time . If you pass over a line, the steer ing
wheel will v ibrate lightly. In order for this warn
i n g vibration to occur, it must f irst be sw itched
on in the Infotainment system . Active lane assist
i s ready for operation whe n the lane marke r line
i s detected on at least one s ide of the vehicle .
The system is designed for driv ing on express
ways and highways and therefore only activates
at speeds above approximate ly 40 mph (65 km/
h).
Applies to vehicles with side assist
If you activate a tur n signa l when active lane as
sist is ready and it class ifies a la ne cha nge as cr it
i cal because of ve hicles t raveli ng a longs ide you o r
approaching you, the re w ill be not iceab le correc
tive stee rin g short ly before you leave t he lane.
This will attempt to keep yo ur vehicle in t he lane.
A ss istance systems
Applies to vehicles w it h out side assist
T he system wi ll not warn yo u before c ross ing a
l ane marker line if you have activated the t urn
s ignal. In this case, it assumes that you are
changing lanes intentionally.
Appl ies to: vehicles with adaptive c ruise control
The co rrective steer ing is targeted based o n the
dr iv ing s itu ation . In add it ion to the lane mar ker
li nes, the system can al so t ake into accoun t other
objects s uch as gua rd rai ls. If they a re detected in
close proximity to t he vehicle, active lane assist
helps p reve nt the vehicle from driving too close
to them. The re is a lso pass ing ass istance. The
system does not provide any corrective steering if it detects that you are pass ing anot her vehicle .
A WARNING
-
-The system warns the drive r that the vehicle
is leaving the lane using corrective steering.
T he drive r is always responsible fo r keeping
the vehicle within the lane.
- T he system can assist the dr iver in keeping
the vehicle in the l ane, but it does not dr ive
by i tsel f. Always keep your hands on the
s teer ing whee l.
- Cor rec tive stee ring may not occur in cert ain
situa tions, such as during he avy b raking .
- T here may be cases whe re t he came ra does
not recogni ze all lane mar ker lines . Cor re c
tive steering can only take pla ce on the s ide
of the vehicle where lane marker lines are
detected.
- Other road structu res or objects could poss i
b ly be identified un intentionally as lane
marker lines. As a result, co rrective steering
may be unexpected or may not occ ur.
- The camera view can be rest ricted, for ex
ample by vehicles driving ahead or by ra in,
snow, heavy spray or light shining into the
camera. Th is can result in active lane ass ist
not detecting the lane marker lines o r de
tect ing them inco rrectly .
- Unde r ce rtain condit ions such as r uts in the
road, a ban ked roadway or crosswinds, the
correct ive steer ing alone may not be enough
to keep the vehicle in the middle of the lane.

In the sporty dynamic mode, the transmission
shifts at higher speed ranges.
Air su spen sion
The adaptive air suspension/adaptive air suspen
sion spo rt* is an e lectron ica lly contro lled a ir sus
pens ion and damping system . The adjustment
depends on the driving mode selected, steering movements, the driver's braking and accelera
tion , and as the road surface, vehicle speed and
load . A sporty sett ing is generally used in vehicles
with adap tive a ir suspension sport*.
The vehicle ground clearance depends on the mode se lected and the speed . When you are in
the auto or dynamic mode, the h ighway sett ing is
activated when you dr ive 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 .
Stee ring
The power steer ing adap ts . Indirect steer ing that
moves easily as in comfort mode is especially
suited to long drives on a h ighway . The dynam ic
mode p rovides spo rty , d irect steering.
Applies to: vehicles with dynamic steering
The steering ratio changes based on vehicle
speed in order to ma intain optimum steering ef
fort for the dr ive r at all times . This sets the steer
i n g to be less sensit ive at hig he r speeds in o rder
to p rovide imp roved vehicle contro l. At reduced
speeds, steer ing is more direct in order to keep
the steering effort as minima l as possib le when
the driv er is maneuvering the v ehicl e. At low and
average speeds, dynamic steering* addit ionally
provides more responsive steering performance.
Sport diff ere ntial *
As a component of the all wheel drive system (quattro)
¢ page 131, the sport differential dis
tributes the driving power to the rear axle de
pending on the situation. The distribution of
power va ries from balanced (comfort) to sporty
(dynamic) depending on the selec ted mode . The
goal is a high level of agility and ab il ity to accel

Adaptive cruise cont rol*
The be hav io r whe n accelerat ing ca n be adjusted
from comfortable to sporty, depending on the drive select mode. Adaptive cruise control also
responds to the driving behavior of the vehicle
