Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 98 Instrument cluster: approach 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 sud­
denly or if your own vehicle is t raveling at a
high speed and approaching a vehicle up
ahead that is moving more slowly . Braking
guard does not react if it cannot detect the
situation.
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 avoid a collision . The indicator
light. in the display comes on .
- The
approach warning is given when a de­
tected vehicle up ahead in your lane is mov ­
i ng much more slowly than you are or if it
brakes sharply . When this warning is given,
it may only be possib le to avoid a collision
by swerving or braking sharply. The indicator
light. and indicator in the display will
warn you about the danger
c::> fig. 98. You
will also hear an acoustic signa l.

This is not ava ilable in som e coun tri es. rl
If you do not react fast enough or do not react
at all to the situation, braking guard will inter­
vene by braking.
- If a col lision is imminent, the system will
first provide an
acute warning by brief ly and
sharply applying the brakes.
- If you do not react to the acute warning,
braking g uard can brake with increasing
force within the limits of the system . This
reduces the vehicle speed in the event of a
co llision.
- The system can initiate maximum braking
shortly before a collision
1 ) . Full deceleration
at high speeds occurs only in vehicles with
adaptive cru ise control and side assist (pre
sense plus) .
- If the braking guard senses that you are not
braking hard enough when a collision is im­
minent, it can increase the brak ing force .
- The pre sense functions also engage when a
collision is imm inent
c::> page 184 .
Which function s can be controlled?
You can switch braking guard and the dis­
tance/approach warning on or off in the MMI
c::> page 88, Settings in the MMI.
A WARNING
Lack of attention can cause collisions, oth­
er 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 responsible for braking at the cor­
rect time.
- Always pay close attent ion to traffic,
even when the braking guard is switched
on. Be ready to intervene and be ready to
take comp lete control whenever necessa­
ry . Always keep the safe and legal dis­
tance between your vehicle and vehicles up ahead .
- Braking guard works within limits and
will not respond outside the system lim­ its, for example when approaching a

88 Audi adaptive cruise control and braking guard
stopped vehicle or stationary obstacle (end of a traffic jam or vehicle that has
broken down in traffic).
- 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 oth­
er 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 de­
tected at all.
- Reflective surfaces including crash barri­
ers or tunnel entrances may impair the
function of the radar sensor.
({) Tips
-You can cancel the braking with increas­
ing force that is initiated by the system
by braking yourself, by accelerating no­
ticeably or by swerving.
- Braking guard error messages
¢page 88.
- Keep in mind that braking guard can
brake unexpectedly . Always secure any
cargo or objects that you are transport­
ing to reduce the risk of damage or in­
jury.

Audi active lane assist
Active lane assist
Description
App lies to vehicles: with active lane assist
Active lane assist helps you keep your vehicle
in your lane .
Active lane assist detects lane marker lines
within the limits of the system using a camera
in the windshield . If you are approaching a de­
tected lane marker line and it appears likely
that you w ill leave the lane, the system will
warn you by means of corrective steer ing . T he
d river can over ride the correct ive steer ing at
any time. If the veh icle crosses a line, the d riv­
er is also warned by a light
vibration in the
steering wheel. The vibration warning must be switched on in the MMI for this to happen.
Active lane ass ist is operable when the line
marking the lane is detected on at least one
side of the vehicle .
If the system is in active standby mode and
the turn signa l is activated before driving over
the lane marker line, the warning does not oc­
cur since the system allows for intentional lane changes.
The system is designed for driv ing on free ­
ways and expanded highways and thus works
only at speeds of 40 mph (65 km/h) or more .
If the vehicle is also equ ipped with Audi adap­
tive cruise control*, the corrective steering
will be more specific in regard to the driving
situation . In addition to the lane marker lines,
the system can also take into account other
objects such as guard rails . If they are detect­
ed i n close prox imity to the veh icle, Audi ac­
tive lane ass ist helps prevent the vehicle from
driving too close to them . There is also pass ­
ing assistance. The system does not provide
any corrective steering if it detects that you
are passing another vehicle.
A WARNING , ~
- The system warns the driver that the ve­
hicle is leaving the lane us ing corrective steer
ing. The driver is always responsible
for keeping the vehicle within the lane .
- The system can assist the driver in keep­
ing the vehicle in the lane, but it does
not steer by itself. Always keep your
hands on the steering wheel.
- Corrective steer ing may not occur in cer­
tain situat ions, such as dur ing heavy
brak ing .
- The camera does not recognize all lane
marker lines. Corrective steer ing can only
take p lace on the side of the vehicle
where lane marker lines are detected .
- Other road structures or objects cou ld
possibly be identified un intent ional ly as
lane marker lines . As a res ult, correct ive
steer ing may be unexpected or may not
occ ur.
- The camera view can be restricted, for
examp le by vehicles driving ahead o r by
r ai n, snow, heavy spray or light shining
into the camera. T his can result in act ive
lane assist not detecting the lane marker
lines or detect ing them incorrectly .
- Unde r ce rtain condi tions such as ruts in
the road, a banked roadway or cross­
winds, the co rrective steering alone may
not be eno ugh to keep the vehicle in the
lane.
- For safety reasons, active lane ass ist
must not be used when there are poor
road and/or weather conditions such as
slippery roads, fog, grave l, heavy rain,
snow and the potential for hydroplaning.
Using act ive lane assist under these con­
d itions may increase the risk of a crash.

ability to accelerate on curves. The vehicle is
very responsive to steering.
Curve light*
The curve light adapts to driv ing on curves.
The pivot ing action and the light ing are also
adapted to the mode.
Ad apti ve crui se contr ol*
The behavior when accelerat ing can be ad just­
ed from comfortable to sporty, depending on
the dr ive se lect mode . Adaptive cruise control
also responds to the driving behav ior of the
veh icle ahead in a more conservative or sporty
manner .
Engine sound
The sound of the engine is adapted to these­
l ected mode and ranges from subtle to sporty.
(D Note
-Make sure there is enough clearance
above and below the vehicle when park­
i ng. The height of the vehicle can change
once it is parked d ue to temperature
fluctuations, changes to the load condi­
tions and changes to the driving modes,
which can affect clearance.
- When transporting the vehicle on a car
carrier, train, ship or by other means, on­
l y tie the veh icle down at the running
surface of the tires, which is the outer
circumference. Securing the vehicle at
the axle components, suspension struts
or tow ing eyes is not perm itted because
the p ressure in the air suspension struts
can change d uring transport. The vehicle
may not be se cured s uff ic ient ly if this
happens.
(D Tips
- In some models, the maxim um vehicle
speed can only be reached in the
Auto
and D ynamic modes.
- Se lecting the
Dynami c mode results in
spor ty sh ifting character istics. The S
gear position engages automatically .

Preventative passenger
protection
A pp lies to veh icles: with Audi pre se nse
Audi pre sense can initiate steps to help pro­
tect vehicle occupants in certain situations.
The functions described depend on equ ipment
installed in your vehicle:
Audi pre sense basic*
The following functions can be triggered in
certain driving situations:
- Tightening of the safety belts (for example,
during heavy braking) : the front safety belts
have reversible belt pretensioners. If a colli­
sion does not occur, the safety belts loosen
slightly and are ready to be tightened again.
- Closing the windows and the sunroof*: the
windows and the sunroof* close leaving a
small open gap.
Audi pre sense basic functions can be trig­
gered at speeds above 20 mph (30 km/h).
Vehicles with Aud i drive select*: the deploy­
ment time is adapted in
Dynamic mode.
Audi pre sense front (vehicles with
adaptive cruise control*)
Audi pre sense front includes the functions in
Audi pre sense basic. In addition, within the
limits of the system, the likelihood of a colli ­
sion with the vehicle immediately ahead is al­
so calculated . If the system senses an immi­
nent collision the following functions can be
tr iggered :
- Braking guard c::>poge
87
-Tightening the safety be lts
- Closing the windows and the sunroof* (leav -
ing a small open gap)
Audi pre sense rear (vehicles with Audi
side assist*)
Audi pre sense rear includes the functions in
Audi pre sense basic. In addition, the likeli­
hood of a rear-end collision with the vehicle
coming from behind is also calcu lated.
If the risk
of a co llision is detected, the following
functions can be triggered:
- Tig htening the safety belts
- Closing the windows and the sunroof* (leav-
ing a small open gap)
Audi pre sense plus*
Audi pre sense plus includes the functions in
Audi pre sense front and Audi pre sense rear.
Error message
Audi pre sense: not available
Preventative passenger protection is not avail­
able. See your authorized Audi dealer immedi­
ately to have the malfunction corrected.
_& WARNING
-=
Audi pre sense cannot overcome the laws
of physics. It cannot prevent a collision. Do
not let the increased safety provided
tempt you to take risks. This will increase
the r isk of a collis ion and serious personal
in juries .
- The sensors cannot always detect all ob­
jects. This increases the risk of a colli­
s10n.
-Aud i pre sense does not detect people or
an im als or objects that are crossing the
veh icle's path c::> page
81.
-The radar sensor's vis ion can be reduced
by heavy rain, ice, snow, heavy road sp ray
and reflections from guard rails, tunnel
entrances, etc. These and similar condi­
tions can prevent vehicles from being ac ­
curately detected and in some cases they
may not be detected at all.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can affect the function of
the Audi pre sense system. Have your au­
thorized Audi dealer check to make sure
that the system is working properly.
