6 mph (10 km/h) and press the brake pedal.
A WARNING
- Never turn off the engine until the vehi
cle has come to a complete stop.
- The brake booster and power steering
only work when the engine is running. If
the engine is off, you have to use more
force when steering or braking. Because
you cannot steer and brake as you usua l
ly would, this could lead to crashes and
serious injur ies.
- For safety reasons, you should always
park your vehicle with the selector lever
in P. Othe rwise, the veh icle could inad
vertent ly roll away.
- After the engine has been switched off,
the radiator fan can continue to r un for
up to 10 minutes - even with the ign it ion

®) at the same
t ime to release the parking brake . The indi
cator light in the switch goes out.
Your veh icle is equipped with an electrome
chan ical parking brake . The parking brake is
designed to prevent the vehicle from rolling unintent ionally and replaces the hand brake.
In addition to the normal functions of a tradi
tional hand brake, the electromechan ical
parking brake provides various convenience
and safety functions.
When starting from rest
-The integral starting assist helps you when
dr iv ing by automatically releasing the park
ing brake
r::!;> page 75, Starting from rest.
- When sta rting on inclines, the starting as
s ist prevents the vehicle from unintentional
ly rolling back . The brak ing force of the
parking brake is not released until sufficient
dr iv ing force has been built up at the
wheels .
Emergency brake function
An emergency brake ensures that the veh icle
can be slowed down even if the
normal brakes
fail ¢
page 76, Emergency braking.
Indicator lights

(0 Tips
-Yo u can apply the parking b rake at any
time - even with the ign ition sw itched
off . The ignition must be on 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
regu lar intervals. Any associated noises
are normal.

Parking
Various rules apply to prevent the parked ve
hicle from rolling away accidentally .
Pa rkin g
.. Stop the vehicle with the foot brake .
.. Pu ll the switch(®) to apply the park ing
brake.
.. Select the
P selector lever position
~page 102 .
.. Turn the eng ine off ~,&. .
In addition on inclines and grade s
.. Turn the steering wheel so that your vehicle
will roll against the curb in case it should
start to move .
A WARNING
-When you leave your veh icle - even if on
ly b riefly - always take the ignition key
with you. This applies particu la rly when
children remain in the veh icle . Otherw ise
the chi ldren could start the engine, re
lease the parking brake or operate elec
trical equipment (e.g. power windows) .
There is the risk of an accident .
- When the vehicle is locked, no one - par
ticularly not children sho uld remain in
the vehicle. Locked doors make it more
difficult for emergency workers to get in
to the vehicle - putting lives at risk.
Starting from rest
The star ting assis t func tion ensures tha t the
parking brake is released automatically upon
starting .
Stopp ing and appl ying park ing b rake
.. Pull the switch<®) to apply the park ing
brake.
Startin g and automatically relea sing the
pa rking br ake
.. When you start to drive as usua l, the park
ing brake is automatically re leased and your
vehicle begins to move.
On th e ro ad 75
When stopping at a traffic signal or s topping
in city traffic, the parking brake can be ap
plied. The vehicle does not have to be he ld
with the footbrake . The parking brake elimi
nates the tendency to creep w ith a dr ive range
engaged. As soon as you drive off as usual,
the parking brake is released automatically
and the veh icle starts to move .
Starting on slope s
When starting on inclines, the starting assist
prevents the vehicle from un intent ionally roll
i ng back. The braki ng force of the parking
brake is not released unti l suff ic ient driving
fo rce has been built up at the wheels .
(D Tips
For safety reasons, the parking brake is re
leased automatically only when the d riv
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 switch<®> pulled and depress the
accelerato r. The parking brake stays applied
and prevents the vehicle from roll ing back
ward .
.. You can release the switch<®) once you are
sure that you are developing enough for
wa rd momentum at the whee ls as you de
press the acce lerator .
Depend ing on the weight of the rig (veh icle
and t ra iler) and the severity of the incline, yo u
may ro ll backwards as yo u start . You can pre
vent rolling backwards by holding the parking
brake switch (®) pulled out and accelerating -
just as you would when starting on a hill with
a conventiona l hand brake.

76 On the road
Emergency braking
In the event that the conventional brake sys
tem fails or locks .
.,. In an emergency, pull the switch(®) and
continue to pull it to slow your vehicle down
with the parking brake .
... As soon as you release the sw itch <®> or ac-
cele rate , the braking process stops.
If you pull the switch <®> and hold it above a
speed of about 5 mph (8 km/h), the emergen
cy braking function is in itiated . The vehicle is
b raked at all four wheels by activating the hy
dra ulic bra ke system. The b ra ke performance
i s simi lar to making an emergency stop ¢
A.
In order not to activate the emergency brak
ing by mistake, an audible wa rning tone (b uz
z e r) sounds when the switch<®> is pulled. As
soon as the switch(®) is released, or the accel
erator pedal is depressed , emergency braking
stops .
&_ WARNING
Emergency braking shou ld only be used in
an emergency, when the normal foot brake
has failed or the brake pedal is obstructed.
Using the parking brake to perform emer
gency braking will slow you r vehicle down
as if you had made a fu ll brake application.
The laws of physics cannot be s uspended
even w ith ESP and its associated compo
nents (ABS, ASR, ED L). In corners and
when road or weather conditions are bad,
a full b rake application can cause the vehi
cle to skid or the rear end to break away -
r isking an accident.
Speed warning system
Introduction
The speed warning system helps you to stay
under a specified maximum speed.
The speed warning system warns you if you
are exceeding the max imum speed that you
have set . You w ill hear a warn ing tone when
your speed exceeds the stored va lue by ap- proximate
ly 3 mph (3 km/h) . An ind icator
light . (USA
models) ;a (Canada models) in
the instr ument cluster d isp lay also turns on at
the same time. The indicator light./.
turns off when the speed decreases be low the
stored maximum speed .
Setting a threshold is recommended if you
would like to be rem inded when you reach a
certain maximum speed. S ituations where you
may wa nt to do so include driv ing in a country
with a general speed limit or if there is a
specified maximum speed for winter tires .
(D Tips
Even though your vehicle is equipped w ith
a speed warn ing system, you should still
watch the speedometer to ma ke sure you
a re not dr iv ing faster than the speed limit.
Setting the threshold
You can set, change and delete the threshold
in the MMI.
.,. Select: !CAR ! function button> Car sy stems
cont rol button > Driver a ssist > Sp eed warn
ing .
You can set any threshold between 20 mph
(30 km/h) and 150 mph (240 km/h) . Sett ings
can each be adjusted in increments of 5 mph
(10 km/h).

A WARNING
-Always pay attention to traffic even when
the cruise control is switched on. You are
always responsible for your speed and
the distance between your veh icle and
other veh icles .
- For safety reasons, the cruise contro l
should not be used in the city, in stop
and-go traffic, on twisting roads and
when road conditions are poor (such as
ice, fog, gravel, heavy rain and hydro
planing) -risk of accident .
- Turn off the cruise control temporarily
when entering turn lanes, highway exit
lanes or in construction zones .
- Please note that inadvertently "resting"
your foot on the accelerator pedal causes the cruise control not to brake. This is
because the cruise control is overridden
by the driver's acceleration.
- If a brake system malfunction such as
overheating occurs when the cruise con
trol system is switched on, the braking
function in the system may be switched off. The other cruise control functions re
ma in active as long as the indicato r light

Adaptive cruis e control an d bra kin g guard 79
Adaptive cruise control
and braking guard
Introduction
App lies to vehicles: with adaptive cruise co ntrol
The adaptive cruise control system assists the
driver by regulating vehicle speed and helping
to maintain a set distance to the vehicle
ahead, within the limits of the system. If the
system detects a moving veh icle up ahead,
adaptive cruise control can brake and then ac
celerate your vehicle . T his helps to make dr iv
ing more comfortable both on long highway
stretches and in stop-and-go traffic.
Aud i brak ing guard can warn you about an im
pending col lision w ith a vehicle up a head that
is slower or has s lowed down and start slow
ing your vehicle down with the brakes
¢page 85.
Adaptive cruise control and Audi brak ing
guard have technica l limitations that you
must know, so p lease read this sect ion care
fu lly, understand how the system works and
use them properly at all times.
General information
General information
Ap plies to vehicles: with adaptive cruise co ntrol
Fig. 81 Fr ont of th e ve hicle : sensors an d video camera
The areas that contain the radar and ultrason
ic sensors and the video camera
¢ fig. 81
must never be covered by stickers, or other
things or coated with dirt, insects, snow or ice
that will interfe re with the adapt ive cru ise
control system and Audi braking guard . Re
move snow with a hand brush and remove ice with a de-icing spray that does not contain
solvents.
T
he function of the Adaptive cruise cont ro l
system and A udi braking guard is limited un
der some conditions.
- Objects can on ly be detected when they are
w ith in sensor range
¢page 81, fig. 84 .
-The system has a limited ability to detect
objects that are a shor t distance ahead,
off
to the side of your vehicle or moving into
your lane from the front or moves into your
lane from the side .
-When driving through curves
¢ page 80.
- Some kinds of veh icles are hard to detect;
for examp le motorcycles, veh icles with high
ground clearance or overhanging loads may
be detected when it is too late or they may
not be detected at a ll.
- Stationa ry objects
c::> page 80.
A WARNING
Improper use of the adaptive cruise con
trol can cause collisions, other accidents
and serious personal injury.
- Never let the comfort and convenience
that adaptive cruise control and Audi brak ing guard offer distract you from the
need to be alert to traffic conditions and
the need to remain in full control of your
veh icle at a ll t imes,
- Always remember that the adaptive
cru ise cont rol and Aud i brak ing guard
have lim its -they will not s low the vehi
cle down or maintain the set d istance
when yo u drive towards an obstacle or
someth ing on or near the road tha t is not
mov ing, such as vehicles stopped in a
traffic jam, a stalled or disabled vehicle.
If registered by the radar sensors, vehi
cles or obstacles that are not moving can
trigger a collision warning and if con
f irmed by the video camera, an acute col
lision warning.
- Always remember that the adaptive
cru ise contro l cannot detect a vehicle
that is driving towards you in your traffic
-
lane and that it cannot detect narrow ..,.
Page 82 of 294

80 Adaptive cruise control and braking guard
vehicles such as motorcycles and bicycles.
- The adaptive cruise control system can
not detect people, animals and cannot
detect objects or traffic that crosses your
lane of travel.
- Never drive at speeds that are too fast
for traffic, road and weather conditions.
- Never use adaptive cruise control when
you cannot drive safely at a steady speed, including on winding roads or
when road conditions are poor (for exam
ple, in construction sites, on ice, gravel,
in fog, heavy rain or on wet roads that in
crease the risk of hydroplan ing).
- Never follow a veh icle so closely that you
cannot stop your vehicle safely. The
adaptive cruise control cannot slow or
brake the vehicle safely when you follow
another vehicle too closely . Always re
member that the automatic braking
function cannot bring the vehicle to a sudden or emergency stop under these
conditions.
- Never rest your foot on the accelerator
pedal, especially when the adaptive
cruise control is being used. Pressure on
the accelerator will override the adaptive cruise control braking function and pre
vent the brakes from being applied when adaptive cruise contro l detects a situa
tion when the brakes must be applied.
- Never use adaptive cruise control when
the radar sensors cannot accurately de
tect vehicles moving in traffic. The radar
sensor's vision can be reduced by heavy
rain, ice, snow, heavy road spray and re
flections from guard rails, tunnel entran
ces, etc. These and similar conditions can
prevent vehicles from being accurately
detected and in some cases they may not
be detected at all .
- Always turn off adaptive cruise control
when entering turn lanes, exit lanes and
construction zones or in similar situa
tions because the vehicle will automati cally accelerate to the stored speed when
the road ahead is clear. -
To prevent unintended operation, always
switch ACC off when it is not being used.
(D Note
The sensors can be moved by impacts or
damage to the bumper, wheel housing and
underbody. Damage in these areas could
change the way the adaptive cruise control
system and Audi braking guard work to
gether . Have your authorized Audi dealer
check to make sure that the adaptive
cruise control system is working properly if
your vehicle had a minor frontal impact or
was damaged in the area of the sensors.
In curves

Audi braking guard
Descript ion
Applies to vehicles: with adaptive cruise contro l
Fig. 90 Instrument cluster: approach warning
Audi braking 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 c ruise
control is switched off.
On vehicles w ith adaptive cru ise control and
Audi side assist (Aud i pre sense plus), system
functions also engage when a collision is im
minent
c::> page 182.
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 veh icle up
ahead that is moving more slowly . Audi brak
in g guard does not react if it cannot detect
the situation.
The system advises you of various s ituations:
- 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 in the disp lay comes on. Take imme- diate action to avoid
the collision 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 sharply. The indicator
light
I and the symbol in the display will
warn you about the danger
c::> fig . 90 . You
w il l also hear an acoustic signal.
If you do not react fast enough or do not react
at all to the situation, Audi braking guard w ill
intervene by braking and the message
braking
guard intervention
will appear.
- If a collision is imminent, the system will
first provide an
acute warning by braking
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 poss ible collis ion. On veh icles with
adaptive cruise control and Audi side assist
(Audi pre sense plus), the system can brake
with increasing force up to maximum dece l
eration shortly before a sensed collision
c::>page 182.
-If the Audi braking guard senses that you
are not brak ing 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 acce lerator 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 i n the
