Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to: vehicles w ith Aud i adapt ive c ru ise co ntro l
Fig. 106 Instrument cluster : approac h warning
Braking guard uses radar sensors and a video
camera. It also functions within the limits of the
system when adaptive cruise control is switched
off .
What can braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes suddenly
or if your own vehicle is traveling at a high speed
and approaching a vehicle up ahead that is mov­
ing more slowly. Braking guard does not react if
it cannot detect the situat ion.
The system advises you of various situations:
- The
distance warning is given if you are too
close to the vehicle ahead for a long time. If the
vehicle ahead brakes sharply, you will not be
able to avo id a coll is ion. The indicator light.
in the display comes on.
- The
approach warning is given when a detected
vehicle up ahead in your lane is moving much
more slowly than you are or if it brakes sharply.
When this warning is g iven, it may only be pos­
sible to avo id a collision by swerving or braking
sharp ly. Th e indicator light. and indicator in
the display will warn you about the danger
qfig. 106. You will also hear an acoustic signal.
If you do not react fast enough or do not react at
all to t he situation, braking guard will intervene
by braking and the message
braking guard inter­
vention
will appear.
l) Thi s is not available in some countries.
96
-If a collision is imminent, the system will first
provide an
acute warning by briefly and sharply
app ly ing the brakes.
- If you do not react to the acute warning, brak­
ing guard can brake with increasing force with­
in the limits of the system. This reduces the ve­
hicle speed in the event of a collision.
- The system can initiate maximum braking
shortly before a co llision
1
) . Full deceleration at
high speeds occurs only in vehicles with adap­
tive cruise control and side assist (pre sense
plus) .
- If the braking guard senses that you are not
braking hard enough when a collision is immi­
nent, it can increase the braking force .
- The pre sense functions also engage when a
collision is imminent
qpage 187.
Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the MMI
¢ page 9 7, Settings in the MMI.
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
comp lete control whenever necessary. Al­
ways keep the safe and legal distance be­
tween your vehicle and veh icles 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 brak ing guard works only within def ined ..,.

Audi active lane assist Lane assist
Description
Applies to: veh icles with act ive lane assist
Active lane assist helps you keep your vehicle in
your lane .
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 by
means of correct ive steering . T he dr iver can over­
ride the correct ive steering at any time. If the ve­
h icle crosses a line, the drive r is also warned by a
light
vibration in the steering wheel. The vibra­
tion warning must be switched on in the MMI for
this to happen. Active lane assist is operable
when the line marking the lane is detected on at
least one side of the vehicle.
The system is designed for driv ing on freeways
and expanded highways and thus works only at
speeds of 40 mph (65 km/h) or more.
Applies to vehicles with side assist* : If you acti ­
vate your turn signal when active lane assist is
ready and when activated side assist has class i­
fied a lane change as critical because of vehicles
traveling alongside you or coming closer, there
will be noticeable corrective steering just before
you leave the lane . Th is is done to try to keep
your veh icle in the lane .
Applies to vehicles without side assist*: when the
system is ready, it does not warn you if you acti ­
vate your turn signal before driving across a lane marker line. In th is case, it assumes that you are
changing lanes intent ionally.
If the vehicle is also equipped with Audi adaptive
cru ise control*, the corrective steering w ill be
more spec ific in regard to the driving situation .
I n addition to the lane marker lines, the system
can also take into acco unt other objects such as
guard rai ls. If they are detected in close prox imi­
ty to the vehicle, Audi active lane assist helps
prevent the vehicle from driv ing too close to
them. There is also passing assistance . The sys-
Audi act ive lane ass ist
tern does not provide any corrective steering if it
detects that you are passing another vehicle .
A WARNING
--The system warns the driver that the vehicle
is leaving the lane using correct ive steering.
The driver 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 steer
by itself . Always keep your hands on the
steer ing wheel.
- Corrective steering may not occur in certain
situations, such as during heavy braking .
- The camera does not recognize all lane
marker lines. Correct ive steering can only
take place on the side of the vehicle where
lane marker lines are detected.
- Other road structures 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 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 incorrectly .
- Unde r certain condit ions such as r uts in the
road, a banked roadway or crosswinds, the
correct ive steer ing alone may not be enough
to keep the vehicle in 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
potential for hydrop lan ing . Using active lane
assist u nder these condit ions may i ncrease
the risk of a crash.

Introduction
Aud i drive select makes it possib le to experience
d ifferent types of veh icle sett ings in one veh icle.
The driver ca n select three
Comf ort, Aut o and
Dyn am ic modes in the MMI to switch between a
sporty and a comfortable driving mode.
You can a lso adjust the setting accord ing to your
p references in the
indi vidual mode. For example,
you can combine settings such as a sporty engine tuning with comfortable steering.
A WARNING
Improper use of the Audi drive select can
cause collisions, other accidents and serious
personal injury.
Description
-
The follow ing systems are affected by drive se­
lect:
Engine and t ransm is sion
Depending on the mode, the engine and the
transmission respond quicker or in a more ba l­
anced manner to accelerator pedal movements.
In the sporty dynamic mode, the transmission
shifts at h igher RPMs.
Air suspe nsion
The adaptive air suspension/adaptive air suspen­
sion sport*
(Air suspension in the MMI) is an
electronically controlled air suspens ion and
damping system . They are adjusted depending
on the se lected dr iving mode, the driver's steer­
ing, b raking and acceleration input and the road
surface, vehicle speed and load. A spo rty setting
is gene rally used in veh icles with adaptive air sus­
pens ion sport*.
The vehicle clearance va ries depending on these­
lected mode and the speed .
The highway setting is activated automatically
when yo u drive above 75 mph (120 km/h) for
mo re than 30 seconds in the
au to or dynamic
106
mode. The ground clea rance is increased auto ­
matically if the speed drops below 44 mph (70
km/h) for more than 120 seconds.
Steering
The steering adapts in terms of steering effort
and steering rat ios. Indirect stee ring that moves
easily, like the steering in com fort mode, is best
suited to long drives on a highway. In contrast,
dynamic mode provides sporty, direct steering .
The following app lies to veh icles with dynamic
steering*: the steering ratio changes based on
vehicle speed in order to maintain optimum
steering effort for the dr iver at a ll times . This
sets the steering to be less sensitive at higher
speeds in order to provide improved vehicle con­
trol. At reduced speeds, however, steering is more d irect in order to keep t he steering effort as
min imal as possible whe n the dr iver is maneuve r­
i ng the vehicle. A t low and ave rage speeds, dy­
namic steeri ng addit ionally prov ides more re ­
spons ive steering performance.
Sport differential*
As a component of the all whee l dr ive sys tem
(quattro)
~ page 195, the Sport differe ntia l*
dist ributes t he d riving powe r to the rear axle de ­
pend ing on the s ituation. The distr ib ution of
power va ries depending on the selected mode,
from ba lanced (comfort) to agile (dynamic). The
goal is a high level of agility and ability to accel­
erate on curves. The vehicle is very responsive to
steering.
Cur ve light *
The curve light adapts to driving on curves . The
pivoting action and the lighting are also adapted
to the mode.
Adapt ive cruise control*
The behavio r whe n accelerating ca n be adjusted
from comfortable to sporty, depending on the
drive select mode. Adaptive cruise contro l also
responds to the driving behavior of the vehicle
ahead in a more conservative or sporty manner . ..,_
