A WARNING
Always pay attention to traffic when adapt ive
cruise control is switched on and braking
guard is active . As the dr iver, you are still re­
sponsible for starting and for maintaining
speed and d istance to other objects. Braking
guard is used to assist you . The driver must
always take action to avoid a collision . The
driver is always responsib le for brak ing at the
co rrect time .
- For safety reasons, do not use adapt ive
cruise co ntro l when driv ing on ro ads w ith
many curves, when the road su rface is in
poor condit ion and/or in bad weather (s uch
as ice, fog, grave l, heavy rain and hydrop la n­
ing). Using the system under these condi­
t ions increases the risk of an accident.
- Switch adaptive cruise contro l 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 adapt ive cru ise control system will not
brake by itself if you put your foot on the ac­
celerator pedal. Doing so can overr ide the
speed and distance regulation .
- When approaching stat ionary objects such
as stopped traffic, adapt ive cru ise control
will not respo nd and braking gua rd will have
l imited func tion .
- The adapt ive cru ise control system and
bra king g uard do not react to people, ani­
mals, objects crossing the road or oncom ing
objects.
- T he function of the radar sensors can be af­
fec ted by reflec tive objects s uch as guard
rai ls, the ent rance to a tunnel, heavy rain or
ice.
& WARNING
- Improper use of adaptive cruise control can cause collisions, other accidents and serious
persona l injury.
- Never let the comfort and convenience that
adaptive cruise cont rol and braking guard
A ss ist
offe r dist ract you from the need to be alert
to traffic cond itions 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 dr ive towa rds an
obstacle or something on or near the road
that is not moving, s uch as vehicles stopped
in a t raff ic jam, a stalled or disab led vehicle.
If r eg istered by the radar sensors, vehicles
or obsta cles that are not moving ca n trigger
a co llision wa rning and if confirmed by the
video came ra, an acute co llision wa rning .
- Never fo llow a vehicle so closely that you
cannot stop your vehicle safely . The adap­
tive cruise contro l cannot slow or brake the
veh icle safely w hen you follow another vehi­
cle too closely. A lways remember that the
automatic braking function cannot bring the
veh icle to a sudde n or emergency stop u n­
der these conditions .
- To prevent unintended operat ion , always
sw itch ACC off when it is not being used .
(D Note
The sensors can be d isplaced by impacts or
damage to the bumper, wheel housing and
underbody. That could affect the adaptive
cruise contro l system and braking gua rd .

Ass is t
When driving into a curve ~ fig. 91 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 . 92 Examp le: ob ject changin g lanes and stationary o b­
j ect
The adaptive cruise contro l system only reacts to
objects that are mov ing or that the system has
a lready detected as moving. 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 @.

• To increase or reduce the distance in incre­
ments, tap the sw itch again to the r ight or left .
The distance between the two veh icles will
change in the instrument cluster display .
When approaching an object ahead, the adaptive
c ruise 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 in
meters

mended. That is equa l to the general recommen­
dation of "half the speed shown on the speedom­
eter" .
The distances provided are specified values . De­

A WARNING
Following other vehicles too closely increases
the risk of coll isions and ser ious personal in­
jury.
- Setting short distances to the traffic ahead
reduces the t ime and distance available to
br ing your vehicle to a safe stop and makes
it even mo re necessary to pay close atten­
t ion to traffic.
- Always obey applicable traffic laws, use
good j udgment, and select a safe following
distance for the traffic, road and weather
condit ions .

Applies to: vehicles with Audi adaptive cruise control
F ig. 98 Instrument c luster: request for driver intervention
In certain situations, the system will request you
to take action:
- if the braking from the adaptive cruise control
system is not enough to maintain enough dis­
tance to the object ahead.
T he danger is indicated by the. indicator light
~ fig. 98. An aud io signa l will also sound.
- Press the brake pedal to slow your vehicle down.
Audi braking guard
Applies to: vehicles with Audi adaptive cruise control
Fig . 99 Instrument cluste r: approac h warning
The braking guard uses radar sensors and a v ideo
camera. It also f unctions w ith in t he lim its of the
system when adaptive cru ise control is switched
off.
What can the b raking guard d o?
When detected in time, the system can assess
dange rous situations where an object ahead
brakes sudden ly or if yo ur own vehicle is trave ling
at a high speed and approaching an object that is
II>

Assist
moving more slowly. The braking guard does not
react if it cannot detect the situation.
The system advises you of various dangerous sit­
uations:
- The
distance warning occurs if you drive too
closely to the object ahead for a long period of
time . If the object ahead brakes strongly, you
would not be able to avoid a collision. The.
indicator light appears as an indication for this.
- The
approach warning occurs when an object
ahead is traveling more slowly or brakes
strongly . When this warning occurs, it may only
be possible to avoid a collision by swerving or
braking strongly. The danger is indicated by the
• indicator light ¢
fig. 99. An aud io signa l will
also sound.
If you do not react early enough or at all to a dan­
gerous situation, the braking guard supports you
with a braking intervention.
- If a collision is imminent, the system will first
provide an
acute warning by braking sharply.
- If you do not react to the acute warning, the
braking guard can increase the braking force
within the limits of the system
1l. Th is reduces
the vehicle speed in the event of a co llision.
- The system can initiate complete deceleration
shortly before a collision
ll. Full deceleration at
high speeds occurs only in vehicles with adap­
tive cruise control and s ide assist (pre sense
plus).
- If the braking guard determines that you are
not braking strongly enough when there is an
impen ding collision, it can increase the braking
force .
- The pre sense functions also engage when
there is an impending collision
¢ page 137.
Which functions can be controlled?
You can switch the braking guard and the dis­
tance/approach warning on or off in the Infotain­
ment system ¢

A WARNING ,_
Lack of attention can cause collisions, other
accidents and serious personal injuries. The
braking guard is an assist system and cannot
prevent a collision by itself . The driver must
always intervene. The driver is always respon­
sible for braking at the correct time.
- Always pay close attention to traffic, even
when the braking guard is switched on. Be
ready to intervene and be ready to take
complete control whenever necessary. Al­
ways keep the safe and legal distance be­
tween your vehicle and vehicles up ahead.
- Braking guard works within limits and will
not respond outside the system limits, for
example when approaching a stopped vehi­
cle or stationary obstacle (end of a traffic
jam or vehicle that has broken down in traf­
fic).
- Always remember that the radar sensor for
the braking guard works only within defined
detection and range limits that may prevent
the proper detection of other vehicles.
- The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Moving vehicles up ahead may not be
promptly detected or may not be detected
at all.
- Reflective surfaces including crash barriers
or tunnel entrances may impair the function
of the radar sensor.
(D Tips
-You can cancel the braking with increasing
force that is initiated by the system by brak­
ing yourself, by accelerating noticeably or
by swerving.
- Keep in mind that braking guard can brake
unexpectedly. Always secure any cargo or
objects that you are transporting to reduce
t he risk of damage or injury.

Audi active Lane assist
Description
Appl ies to: ve hicles w ith Audi active lane assist
Active lane assist detects lane marker lines with­
in 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
correct ive steering . You can ove rride th is steer ing
at any time . If you pass over a line, the steer ing
wheel will v ibrate l ightly. In order for this warn­
ing vib ration to occur, it must fi rst be sw itched
on in the Infotainment sys tem . Active 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 highways and therefore only activates
at speeds above approximately 40 mph (65 km/
h).
A pp lies to: ve hicles w ith s ide assist
If you activate a turn sig na l 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 noticeab le correc­
tive steering shortly before you leave the lane.
This will attempt to keep your vehicle in the lane.
A ppl ies to: ve hicles w ithout s ide ass ist
The system will not warn you before crossing a
lane marker line if yo u have activated the tu rn
signa l. In this case, it ass umes that you are
changing lanes intentiona lly .
A ppl ies to: ve hicles with adaptive cruise co ntrol
The corrective stee ring is targeted based on the
driving situat ion . In addition to the lane marker
96
li nes, the system can a lso take into account other
objects 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 a lso pass ing ass istance. The
system does not provide any corrective steering if i t detects that you are pass ing another vehicle .
A WARNING
-The system warns the drive r that the vehicle
is leaving the lane using cor rect ive steering.
The drive r is always responsible fo r keeping
the vehicle within the lane.
- The system can help you keep the vehicle in
the lane, but it does not drive by itse lf. Al­
ways keep your hands on the steering
wheel.
- Cor rective steering m ay no t occur in certain
si tuations, such as during heavy braking.
- There may be cases where t he camera does
not recognize all lane marker lines . Correc ­
tive steering can only take place on the s ide
of the vehicle where lane marker lines are
detected.
- Other road structures or objects could possi­
bly be identified unintent ionally as lane
marker lines. As a result, corrective steering
may be unexpected or may not occur.
- The camera view can be restricted, for ex­
ample by vehicles driving ahead or by rain,
snow, heavy spray or light shining into the
camera . This can result in active lane ass ist
not detecting the lane marker lines or de­
tect ing them inco rrectly .
- Under certain cond it ions such as ruts in the
road, a banked roadway or crosswinds, the
corrective steer ing alone may not be enough
to keep the vehicle in the m iddle of the lane.
- For safety reasons, act ive la ne assist must
no t be use d when there are poor road and/
or weather condi tions such as slippery
roads, fog, gravel, heavy rain, snow and the potential for hydrop laning. Using active lane
assist under these conditions may increase
the risk of a crash.

The adjustment depends on the driving mode se ­
l ected, steering movements, the driver's brak ing
and accelerat ion, and as the road su rface, vehicle
speed and load.
The vehicle ground clearance depends on the mode se lected and the speed . When you are in
the
auto , the highway setting is act ivated when
you dr ive above 75 mph (120 km/h) for more
than 30 seconds. The g round clearance is in­
creased automat ica lly if the speed drops below
44 mph (70 km/h) for more than 120 seconds .
Steering
The power steering adapts. Ind irect steering that
moves easily as in comfort mode is especially
sui ted to long drives on a h ighway. The Dynamic
mode provides sporty, direct steering .
Applie s to: vehicles with dynamic steering
The steering ratio changes based on vehicle
speed in order to maintain optimum steering ef­
fort for the dr iver at a ll times. This sets the steer­
i ng to be less sensit ive at higher speeds in order
to p rovide imp roved vehicle contro l. At reduced
speeds, steer ing is mo re direct in order to keep
t he s teering effo rt as m inima l as poss ib le when
t he dr iver is maneuvering the vehicle . At low and
ave rage speeds, dynamic steering* additionally
p rovides more responsive stee ring performance.
Sport differential *
As a component of the all wheel d rive system
(quattro)
<=? page 124 , the sport diffe rential dis ­
tr ib utes the dr iv ing power to the rear ax le de­
pending on the situation. The distribution o f
power varies from balanced (comfort) to sporty
(dynamic) depending on the selected mode . The
goa l is a high leve l of agility and ab ility to accel­
erate on curves. The ve hicle is very respons ive to
steer ing.
Cornering light*
The cornering light adapts the high beams to the
direction of the curve depending on the speed.
The pivot ing action and the light ing also adapt to
~ t he mode . .... N
" N .... 0 0 <..:l - Assist
Adaptive cruise control*
T he behavio r whe n accelerating 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
ahead in a more conservative or sporty manner.
Engine sound *
The eng ine sound adapts to the c urren t mode
and can be subtle to sporty.
(D Note
Applies to: vehicles with adaptive ai r suspension
- Make sure there is enough clearance above
and be low the vehicle when parking. The
height of the vehicle (gro und clearance) can
change once it is parked due to temperature
fluctuations, changes to the load conditions
and changes to the dr iving modes .
- When transporting the vehicle on a car car­
r ie r, train, ship or by other means, o nly tie
the vehicle down at the run ning s urface of
the t ires , which is the outer c ircumference.
Se cur ing the vehicle at the axle compo­
nents, sus pen sion str uts o r towing eyes is
no t perm itted because the pressure in the
air suspens ion struts can change d uring
transport . The vehicle may not be secured
sufficiently if th is happens .
(D Tips
-In some models, the maximum vehicle
speed can only be reached in the auto and
dynamic modes.
- The S selector lever position automatica lly
engages if the dynamic mode is selected.
- Applies to: vehicles with dynamic steering:
operating noise is heard when starting or
stopping the engine. Th is does not ind icate

your risk of a collision.
- Please note the risk of a co llision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv­
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre­
vent collisions -there is still a r isk of acci­
dents!
- Press the accelerator pedal carefully when

increase the risk of a collision.
(D Tips
- ABS and ASR only function correctly when
all four wheels are equipped with identical
