.&_ WARNING
Following other vehicles too closely in­
creases the risk of co llisions and serious
personal injury.
- 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 more necessary
to pay close attention to traffic.
-
-Always obey applicable traffic laws, use
good judgment, and select a safe follow­
ing distance for the traffic, road and
weather conditions .
@ Tips
-Distance 3 is set automatically each time
you switch the ignition on.
- Your standard settings are automatically
stored and assigned to the remote con­
trol key being used.

92 Audi adaptive cruise control and braking guard
Audi braking guard
Descript ion
App lies to vehicles: with Audi adap tive cruise control
Fig. 96 Instrument cluster: approach warn ing
Braking guard uses radar sensors and a video
camera . It also functions within the limits of
the system when adapt ive 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 traveling at a
high speed and approaching a vehicle up
ahead that is moving more slowly . Brak ing
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
I in the display comes on .
- The
approach warning is given when a de­
tected veh icle 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 possible to avoid a collision
by swerving or braking sharply. Th e indicator
light
I and indicato r in the display will warn
you about the danger¢
fig. 96. You will a lso
hear an acoustic signal.
If you do not react fast enough or do not react
at all to the situation, braking guard will inter-
ll This is not ava ilable in some co un tri es .
vene by braking and the message braking
guard intervention
wi ll appear.
- If a coll is ion is imm inent, the system wi ll
fi rst prov ide an
acute warning by briefly and
sharply applying the brakes.
- If you do not react to the acute warning,
braking guard can brake with increas ing
force within the limits of the system . This
reduces the vehicle speed in the event of a
collision.
- The system can initiate maximum braking
short ly before a co llision
1l . Full deceleration
at high speeds occurs only in vehicles with
adaptive cruise control and side assist (pre
sense plus) .
- If the braking guard senses that you are not
braking hard enough when a collision is im­
m inent, it can increase the braking force .
- The pre sense functions also engage when a
collision is imminent¢
page 194.
Which function s can be controlled?
You can switch braking guard and the dis­
tance/approach warning on or off in the MMI
i=> page 93, 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 dr iver is
a lways respons ible for braking at the cor­
rect 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 necessa­
ry. Always keep the safe and legal dis­
tance between your veh icle and vehicles
up ahead.
- Braking guard works within limits and
will not respond outside the system lim­
its, for example when approaching a
stopped vehicle or stationary obstacle ..,.

(end of a traffic jam or veh icle t hat has
br oken down in traffic).
- Alw ays remember that the radar sensor
for the b raking guard works only within
defined detection and ra nge limits that
may prev ent the proper det ection of oth­
er ve hicles.
- The ra dar 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 al l.
- Reflective surfaces includ ing crash barr i­
ers or tunnel ent rances may impair the
function of the radar sensor.
(0 Tips
- You can cance l the braking w ith increas­
i ng fo rce that is initiated by the system
by braking yo urself, by accelerating no­
ticeab ly or by swerving.
- Brak ing guard error messages
<=> page 93.
-Keep in mind that braking guard can
brake unexpectedly. Always secure any
ca rgo or objec ts that you are transport ­
i ng to reduce t he risk of d amage o r in­
Ju ry.

Audi active Lane assist
Active Lane assist
Description
Applies 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
driver can over ride the cor re ct 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 whee l. 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 equipped with Audi adap­
tive cruise control*, the corrective steering
will be more specif ic in regard to the driving
situation . In addition to the lane marker lines,
the system can a lso take into acco unt other
objects such as guard rails. If they are detect­
ed i n close proximity to the veh icle, Audi a c­
tive lane ass ist helps prevent the vehi cle from
driving too close to them . The re 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
Audi acti ve lane a ssis t 95
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. A lways keep your
hands on the steering wheel.
- Corrective steering may not occur in cer­ tain sit uat 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 ionally as
lane ma rker lines. As a result, cor rect ive
steer ing may be unexpected or may not
oc cur .
- The camera view can be restricted, for
examp le by vehicles driving ahead o r by
r ai n, snow, heavy spray or light s hining
into the camera. This can result in a ctive
lane assist not detecting the lane marke r
lines or detect ing them inco rrectly .
- Unde r ce rtain condi tions such as ruts in
the road, a banked roadway or cross­
winds, the corrective stee ring alone may
not be enough 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 condit ions such as
slippery roads, fog, gravel, heavy rai n,
snow and the potent ial for hydroplaning .
Using act ive lane assist under thes e con­
ditions may increase the risk of a crash.

tion zone or because they are obstructed by
snow, dirt, water or backlight ing).
- The vehicle 's speed is below the speed need ­
