82 On the road
-Occasiona l noises when the parking
brake is applied and re leased are norma l
and are not a cause for concern .
- When the vehicle is parked, the parking
brake goes through a se lf-test cycle at
regular intervals. Any assoc iated noises
are norma l.
Parking
Various rules apply to prevent the parked ve­
hicle from rolling away accidentally.
P ar king
,. Stop the vehicle w ith the foot brake.
,. Pull the switch© to apply the parking
brake.
,. Se lect the
P se lector lever position

,. Turn the eng ine off q _&. .
In addition on incline s and grad es
,. Turn the steering whee l so that your vehicle
wi ll ro ll against the curb in case it should
start to move .
A WARNING
-When you leave your veh icle -even if on­
ly briefly -always take the ignition key
with you. This applies particularly when children remain in the veh icle. Otherw ise
the ch ildren could sta rt t he engine, re­
lease the p arking brake or operate e lec­
trical equipment (e .g. power windows) .
T he re is the risk of an accident.
- When the vehicle is loc ked, no one -par­
t icu la rly not children sho uld remain in
the vehicle . Locked doors make it more
difficult for emergency workers to get in­
to the vehicle -putt ing lives at risk.
Start ing from rest
The starting assist function ensures that the
parking brake is released automatically upon starting.
Stopping and appl ying par kin g brake
,. Pull the switch© to apply the parking
brake.
St arting and automatic ally rel easi ng the
parking b rake
,. When you start to dr ive as usual, the park ­
ing brake is automat ically released and your
veh icle beg ins to move.
When stopping at a traffic signal or stopping in city traffic, the parking brake can be ap­
plied . The vehicle does not have to be held
with the footbrake . The parking brake elimi ­
nates the tendency to creep w ith a dr ive range
engaged. As soo n as you d rive off as usual,
the pa rking brake is re leased automatically
and the vehicle s tarts to move.
Sta rting on slopes
When starting on inclines, the starting assist
prevents the veh icle from u nintent ionally roll­
i ng back. The braking fo rce of the par kin g
brake is not re leased unti l su ff ic ient d riving
f orce has been built up a t the wheels.
(D Tips
Fo r safety reasons, the pa rking bra ke is re­

er's safety belt is engaged in the buckle.
Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
,. Keep the sw itch(®) pulled and depress the
accelerator. The pa rking brake stays applied
and p revents the vehicle from roll ing back­
ward .
,. You can release the switch© once you are
sure that you are developing enough for­
ward momentum at the whee ls as you de ­
press the acce lerator.

Audi braking guard
Description
Applies to vehicles: wit h adapt ive c ru ise control
Fig. 94 Instrument cluster: approach warn ing
Audi brak ing guard uses radar sensors and a
video camera . It is active at speeds above
about 6.2 mph (10 km/h) and also works
within system limits when adaptive cruise control is switched off.
On vehicles with aAdaptive cruise control and
Audi side assist (Audi pre sense plus), system
functions also engage when a co llision is im­
minent
¢page 188.
What can Audi braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes sud­
denly or if your own veh icle is traveling at a
h igh speed and approaching a vehicle up
ahead that is moving more slowly. Audi brak­
ing guard does not react if it cannot detect
the situation.
The system advises you of various kinds situa­ tions :
- 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 coll is ion. The ind icator
light
I i n the d isplay comes on. Take imme ­
diate action to avoid the coll is ion and in­
crease the distance to the vehicle up ahead. -
The
approach warning is given when a de­
tected vehicle up ahead in your lane is mov­
ing much more slowly that you are or if it
brakes sharp ly. When this warning is given,
it may only be possible to avoid a collision
by swerving or braking sharp ly . The indicator
light
I and the symbol in the disp lay will
warn you about the danger
c:> fig. 94 . You
w ill also hear an acoustic signal.
If you do not react fast enough or do not react
at all to the situation, Aud i braking guard w ill
intervene by braking and the message
braking
guard intervention
w ill appear.
- If a coll is ion is imminent, the system will
first provide an
acute warning by brak ing
sharply .
- If you do not react to the acute warning, Au­
di braking guard will brake w ith increased
force in severa l stages to reduce the speed
in a possible collisio n. On ve hicles w ith
adaptive cruise contro l and Audi side assist
(Audi pre sense plus), the system can brake
with increasing force up to maximum decel­
eration shortly before a sensed collision
¢ page 188.
- If
the Audi braking g uard senses that you
are not braking hard enough when a colli­
sion is imminent, it can increase the braking
force.
Audi braking guard takes the driver's reaction
time into consideration in order to provide
timely warnings. The system reaction time de­ creases automatically in some situations, for
example when it detects accelerator pedal use
or steering input . The Audi braking guard in­
tervent ion stops in certa in situations, for ex­
amp le if you press the accelerato r pedal to
pass the vehicle moving ahead of you in your
lane.
Which functions can be controlled?
You can switch Audi braking guard and the
distance/approach warning on or off in the

Audi lane assist Lane assist
De scription
App lies to vehicles: with la ne ass ist
Lane assist helps you keep your vehicle in your
lane.
Lane assist uses a camera to detect lane boun ­
dary lines . If the system detects that your ve­
hicle is about to cross a detected lane boun­
dary line, the steering wheel
vibrates to alert
the driver . Lane assist is operable when the
line marking the lane is detected on at least
one side of the veh icle. This is ind icated by a
g reen indicator light. in the instrument
cluster.
If the system is in active standby mode and
the turn signal is activated before driving over
the bounda ry line, the warn ing does not occur
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.
A WARNING
- Lane assist will not keep your vehicle in
your lane . The system only warns the
driver when the vehicle is leaving the
lane . The driver is always responsible for
keeping the vehicle in the lane .
- The camera is not able to detect all lane
boundary lines and in some cases might
also detect lane structures or objects as
boundary lines . This can lead to incorrect
warnings or wa rnings tha t fail to go off
at all.
- The camera's visibility can be impaired by
vehicles ahead of you, for instance, or by
rain, snow, heavy spray o r light sh in ing
into the camera lens. Th is can cause lane
assist to fa il to detect boundary lines.

When the lane assist turns off automatically,
the instrument cluster indicator goes out and
one of the following messages appears on the
display:
Audi lane assist not available: Currently no
sensor vision
This message appears when the camera can
no longer function because it cannot detect
the boundary lines. This may be due to the
following:
- T he exterior side of the camera viewing win­
dow
r:!:> fig. 96 is covered with dirt or ice.
Clean this part of the windshield.
- The camera viewing window is fogged up on
the inside. In this case, wait until the fog
disappears before turning lane assist on
again.
- The system was unab le to detect boundary
lines over an extended period of time due to
road conditions (such as snow-covered
lanes). Do not turn lane assist on again until
the lines can be more easily detected.
Audi lane assist not available
A temporary malfunction is preventing lane
assist from operating. Try turning on lane as ­
sist again at a later t ime.
Audi lane assist: system fault
The system should be checked by an author­
ized Audi dealer or other qualified workshop.
(D} Tips
-Make sure that the camera v iewing win­
dow

App lies to vehicles: with lane ass ist
You can adjust individual settings in the MMI.
~ Select : ICARI function button> Car systems
control button > Driver assist > Audi lane
assist.
Setting the warning point Early:
With this setting, a warning is provided
before a wheel touches the detected lane
boundary line. The warning depends on the
angle in which the vehicle is approaching the
line. The distance at which the warning is giv­
en increases as the angle becomes sharper. If
you drive toward a boundary line at a very sharp angle, the warning will come just before
a wheel touches the line.
Medium: With this setting, the warning point
is adapted to the course of the road, the lane
width and the speed. You will still be warned
Audi lane assist 97
if you cross slightly over a dotted line when
driving on curves.
Late: This setting has the same properties as
medium. You will only be warned once a
wheel crosses a detected line.
Setting the steering wheel vibration
The steering wheel vibration can be set to
Low, Medium or Strong. Selecting each of the
settings will cause the steering wheel to vi­
brate so you can check the strength of the vi­
bration in that setting.

(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 due to temperature
fluctuations, changes to the load condi­
tions and changes to the driving modes,
which can affect clearance .
- When transporting the veh icle on a car
carr ier, train, ship or by other means, on­
ly tie the vehicle down at the running
surface of the tires, which is the outer
circumference . Secur ing the vehicle at
the axle components, suspension struts
or towing eyes is not permit ted because
the pressure in the air suspension struts
can change during transport. The vehicle
may not be secured sufficient ly if this
happens.
- If you a re going to tow a trailer, you
must activate the trailer operation mode
