cator light in the switch goes out.
Your vehicle is equipped with an electrome ­
chan ical park ing brake . The parking brake is
designed to prevent the vehicle from rolling
un intent ionally and rep laces the hand brake.
In addition to the normal functions of a tradi ­
tional hand brake, the electromechan ical
parking brake provides var ious convenience
and safety functions.
When starting from rest
-The integral starting assist helps you when
driving by automat ically releasing the park­
ing brake ¢
page 78, Starting from rest.
- When starting on inclines, the starting as ­
sist prevents the vehicle from unintentional­
ly rolling back . The braking force of the
parking brake is not released until suff icient
driv ing force has been built up at the
wheels.

(0 Tips
-Yo u can apply the parking brake at any
time -even with the ignition switched
off. The ignition must be on and the
brake pedal must be pressed in order to
release the parking brake.
- Occasional noises when the parking
brake is applied and released are normal
and are not a cause for concern.
- When the vehicle is parked, the parking
brake goes through a self-test cycle at

even with ESC and its associated
components (ABS, ASR, EDL). In corners
and when road or weather conditions are
bad, a full brake application can cause the
vehicle to skid or the rear end to break
away· risking an accident.
Speed warning system
Introduction
The speed warning system helps you to stay
under a specified maximum speed.
The speed warning system wa rns you if you
are exceeding the maximum speed that you
have set. You will hear a warn ing tone when
your speed exceeds the stored value by ap­
proximately 3 mph (3 km/h). An indicator
light . (USA models)/ . (Canada models) in
the instrument cluster display also turns on at
the same time. The indicator light ••
turns off when the speed decreases below the
stored maximum speed .
Setting a threshold is recommended if you
would like to be reminded when you reach a certain max imum speed . Situations where you
may want to do so include driving in a country
with a general speed limit or if there is a
specified maximum speed for winter tires.
@ Tips
Even though your vehicle is equipped with
a speed warning system, you should st ill
watch the speedometer to make sure you
are not driving faster than the speed limit.
Setting the threshold
You can set, change and delete the threshold
in the MMI.
.. Se lect : I CARI function button > (Car)* sys­
tems
control button > Driver assist > Speed
warning .
You can set any threshold between 20 mph
(30 km/h) and lS0 mph (240 km/h) . Settings
can each be adjusted in inc rements of 6 mph
(10 km/h).

When approaching a moving vehicle up ahead,
the adaptive cruise control system automati­
cally brakes to match that object's speed and
then maintains the stored distance. If the ve­
h icle ahead accelerates, adaptive cruise con­
trol will also accelerate up to the stored
speed.

A WARNING ,. -
Following other vehicles too closely in­
creases the risk of collisions and serious
personal inj ury.
- Setting short distances to the traffic
ahead reduces the time and distance
available to bring 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 d istance for the traff ic, road and
weather conditions.
@ Tips
- Distance 3 is set automatically each time
you switch the ignition on.
- Your standard settings are automatically

Audi adaptive cruise control and braking guard 87
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 96 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
I 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. The indicator
l ight
I and indicator in the display will warn
you about the danger
c::> fig . 96. You will a lso
hear an acoustic signal.
11 This is not ava ilable in som e coun 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.
- I f a collision 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 g uard can brake with increasing
force within the limits of the system . This
reduces the vehicle speed in the event of a
collision.
- 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 187 .
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

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.
