92 Audi adaptive cruise control and braking guard
Audi braking guard
Descript ion
Applies to vehicles: with Audi adaptive cruise control
Fig. 99 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. 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 possible to avoid a collision
by swerving or braking sharply . Th e indicator
light. and indicator in the display will
warn you about the danger
c::> fig. 99. You
will also hear an acoustic signa l.
ll This is not ava ilable in some co un tri es .
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 coll is ion is imminent, the system will
first provide an
acute warning by briefly and
sharply applying the brakes.
- If you do not react to the acute warning,
braking guard can brake wit h increasing
force w ith in 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 collision
1l . Full deceleration
at high speeds occurs only in vehicles with
adapt ive 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
c::> page 192.
Which functions can be controlled?
You can switch braking guard and the dis­
tance/approach warning on or off in the MMI
c::> 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 driver is
always respons ible for braking at the cor­
rect time.
- Always pay close att ent 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 ..,.

stopped vehicle or stationary obstacle
(end of a traff ic jam or veh icle 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 dete cted or may not be de­
tected at all.
- Reflective surfaces in cl ud ing crash barr i­
ers or tunnel ent rances may impai r the
f unc tion of the radar sensor.
(D Tips
- You can ca nce l the braking w ith increas­
i ng force that is initiated by the system
by b raking yo urself, by accelerating no­
tice ably or by swerving.

i ng to reduce the risk of damage 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.

- There is no lane marker line .
- The relevant lane marker lines are not de-
tected (for example, markings in a construc­
tion zone or because they are obstructed by
snow, dirt, water or backlight ing).
- The vehicle' s speed is below the speed need ­
ed to activate it, which is about 40 mph (65
km/h) .
- The lane is narrower than about 8 ft . (2 .5 m)
or wider than 15 ft (4 .5 m).

Side assist functions at speeds above approx i­
mately 19 mph (30 km/h).
@ Vehicl es th at ar e approaching
In certain cases, a vehicle will be classified as
cr itical for a lane change even if it is still
somewhat far away. The fas ter a vehicle ap­
p roaches, the sooner the display in the exteri­
or m irror will t urn on.
@ Vehicles traveling with you
Vehicles traveling w ith you are indicated in the
exterior m irror if they are classified as cr itical
for a lane change. All vehicles detec ted by
side assist are indicated by the time they en­
ter your "blind spot", at the latest.
Audi side assist 99
@ Veh icle s left behind
If you s low ly pass a vehi cle that s ide assist has
detected (the difference in speed between the
vehicle and you r vehicle is less than 9 mph or
15 km/h), the display in the exterio r mir ror
turns on as soon as the vehicle enters your blind spot.
T he disp lay will not t urn on if you quickly pass
a vehicle that side assist has detected (the dif­
ference in speed between the veh icle and your
vehicle is greater than 9 mph or 15 km/h).
Functi onal limitations
The radar sensors are designed to detect the
left and right adjacent lanes when the road
lanes are the normal width. In certain situa­
tions, the d isp lay in the exterior mirror may
turn on even though there is no veh icle locat­
ed in the area that is cr itical for a lane change.
For example:
- if the lanes are narrow or if your are dr iving
on the edge of your lane.
If this is the case,
the system may have detected the vehicle in
another lane that is
not adjacent to your
current lane .
- if you a re driving through a curve. Side assist
may react to a vehicle that is one lane ove r
from the adjacent lane.
- if side assist reacts to other objects (such as
high or d isp laced guard rails) .
- In poor weather conditions. The side assist
functions are l imited .
Do not cover the radar sensors
c> fig. 10 7 with
stickers, depos its, bicycle wheels or other ob­
jects, because this will affect the funct ion. Do
not use s ide ass ist when towing a trailer. For
i nformation on cleaning, refer to
c> page 212 .
_&. WARNING
-Always pay attention to traffic and to t he
area a round your ve hicl e. S ide assist can­
not replace a driver's attention. T he driv­
er a lone is always responsible for lane
changes and similar driving mane uvers.

100 Audi side assist
-Improper reliance on the side assist sys­
tem can cause collisions and serious
personal injury:
- Never rely only on side assist when
changing lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles un­
der all conditions- danger of accident!
- Please note that side assist indicates
there are approaching vehicles, or
vehicles in your blind spot, only after
your vehicle has reached a driving speed of at least 19 mph (30 km/h).
- In certain situations, the system may not
function or its function may be limited.
For example:
- if veh icles are approaching or being left
behind very quickly . The display may
not turn on in time.
- in poor weather conditions such as
heavy rain, snow or heavy mist .
- on very wide lanes, in tight curves or if
there is a rise in the road surface.
Vehicles in the adjacent lane may not
be detected because they are outside
of the sensor range.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can affect the system.
Have your authorized Audi dealer or au­
thorized Audi Service Facility check their
function.
@ Tips
- If the window glass in the driver's door
or front passenger's door has been tint­ ed, the display in the exterior mirror may
be misinterpreted.
