Your vehicle is equipped with an electrome­
chanica l parking brake. The parking brake is
designed to prevent the vehicle from rolling unintentionally and replaces the hand brake .
In addition to the norma l functions of a tradi­
tional hand brake, the electromechanical parking brake provides various convenience
and safety functions.

When starting from rest
- The integral start ing assist helps you when
driving by automatically re leasing the park­
ing brake c>
page 80, Starting from rest.
-When start ing on inclines, the starting as­
sist p revents the vehicle from unintentiona l­
ly rolling back. The braking force of the
parking brake is not re leased until sufficient
driving force has been built up at the
wheels.
Emergency brake function
An emergency brake ensures that the vehicle
can be slowed down even if the
normal brakes
fail

A WARNING
Do not press the accelerator pedal inadver­
tently if the veh icle is stationary but the
engine is running and a gear is selected .
Otherwise th e vehicle w ill start to move
immediately and could result in a crash.
@ Tips
- If the parking brake is applied with the
ignition switched
off, the indicator lights
in the switch and. (USA models)/ •
(Canada models) in the instrument clus­
t er w ill go out after a certain period of
time.
- Occasional noises when the parking
brake is applied and released are normal
and are not a cause for concern.
- When the vehicle is pa rked, the parking
brake goes through a self-test cycle at
regu lar intervals. Any associated noises
are normal.

80 On the road
& WARNING
-When you leave your vehi cle -even if on­
ly brief ly -always take the ignition key
with yo u. This applies par ticu larly when
children remain in the veh icle. Otherw ise
the ch ildren 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
t icularly not children should remain in
the vehicle. Loc ked doors make it more
difficult for emergency wor kers to get in­
to the vehicle - putt ing lives at risk.
Starting from rest
The starting assist function ensures that the
parking brake is released automatically upon starting.
Stopping and applying parking brake
" Pull the switch ID to apply the park ing
brake.
St arting and automa tically relea sing the
parking brake
.. When you start to drive as usua l, the park­
ing brake is automatically released and you r
vehicle begins to move.
When stopp ing at a traff ic signa l or stopp ing
in city traffic, the parking brake can be ap­
plied . The veh icle does not have to be held
with the footbrake. The par king brake elimi­
nates the tendency to c reep with a drive range
engaged. As soon as you dr ive
off as usua l,
the park ing brake is released automatically
and the vehicle starts to move.
Starting on slopes
When sta rt ing on in cl ines, the starting ass ist
p revents the veh icle from uninten tionally ro ll­
ing bac k. The braking force o f the parking
brake is not released un til sufficient dr iving
force has been b uilt up at the whee ls.
(D Tips
For safety reasons, the parking bra ke is re­
l eased automatically only when the driv­
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 bra ke 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 wheels as you de­
press the acce lerator.
Depend ing on the we ight of the rig (vehicle
and trailer) and the severity of the incline, you
may roll backwards as you start. You can p re­
vent rolling backwa rds by holdi ng the par king
brake switch (®) pulled o ut and ac celera ting -
j u st as you wou ld w hen s tarti ng on a hill wi th
a conventiona l hand brake.
Emergency braking
In the event that the conven tional brake sys­
tem fails or locks.
"I n an emergency, pull the switch(®) and
cont inue to pull it to slow your ve hicl e down
w ith the par king b rake.
" As soon as you re lease the swi tch (®) or ac -
celerate, the braking process stops.
If you p ull the swi tc h (®) a nd hold it above a
speed of about 5 mph (8 km/h), the emergen­
cy braking f unction is initiated. The ve hicle is
braked at all four whee ls by activating the hy­
draulic brake system. The brake performance
is similar to making an emergency stop¢&..
In order not to activate the emergency brak-
ing by mistake, an audib le warning tone (buz ­
zer) 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 should 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 your vehicle down
as if you had made a full brake applicat ion.
The laws of physics cannot be suspended
even with ESC and its associated compo­
nents (ABS, ASR, EDL). In corners and
when road or weather conditions are bad
'
a full brake 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 exce edin g the maximum speed that you
have set. You will hear a warning 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 be low the
stored maxim um speed.
Setting a threshold is recommended if you
would like to be reminded when you reach a
certain maximum speed. Situations where you
may want to do so incl ude driving in a co untry
with a general speed limit or if there is a
specified maximum speed for winter tires.
@ Tips
Even though your vehicle is equipp ed w ith
a speed warning system, you sho uld still
watch the speedometer to make sure you
are not driv ing faster than the speed limit.
Setting the threshold
You can set, change and delete the threshold
in the MMI.

A WARNING
--Always pay attent ion to traffic even when
the cruise control is switched on. You are always responsible for your speed and
the distance between your vehicle and
other vehicles.
- 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
p lan ing) -risk of accident .
- Turn off the cruise control temporarily
when entering turn lanes, highway exit
lanes or in constr uction zones .
- Please note that inadve rtently "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 sw itched
off. The other cruise control functions re­
main active as long as the indicator light

Audi adaptive cruise
control and braking
guard
Introduction
App lies to vehicles: with Audi adaptive cruise co ntrol
The adaptive cruise control system assists the
driver by regu lat ing 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 vehicle up ahead,
adaptive cruise control can brake and then ac­
celerate your vehicle. This helps to make driv­
ing more comfortable both on long highway
stretches and in stop-and-go traffic.
The braking guard system can warn you about
an impending collision and initiate braking
maneuvers
c:::> page 92.
Adaptive cruise control and braking guard
have technical limitations that you must
know, so please read this section carefully, un­
derstand how the system works and use them
properly at all times.

must neve r be cove red by stic kers or other ob­
jects or obstructed w ith dirt, insects, snow or
i ce that will interfere with the adaptive cruise
control system and braking guard. For infor­
mation on cleaning, refer to
c:::> page 212. The same applies for any modifications made in
the front area.
T he function of the adaptive cru ise contro l
system and braking guard is limited under
some cond itions:
- Objects can only be de tected when they are
w ith in sensor range
c:::>page 88, fig. 92.
- The system has a limited ability to detect
objects that are a short d istance ahead, off
to the side of your vehi cle or mov ing into
your lane.
- Some kinds of ve hicles 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 all.
-When driving through curves
c!,>page 87 .
-Stat ionary objec ts c:::> page 87.
& WARNING
A lways pay attention to traffic when adap ­
tive cruise contro l is switched on and brak­
ing g uard is active. As the dr iver, you are
still respons ible for starting and for main­
taining speed and distance to other ob­
jects. Braking guard is used to assist you .
The dr iver must a lways take action to avo id
a collis ion . The driver is a lways respons ible
fo r braking a t the co rrec t time.
- Imp roper use of adaptive cru ise control
can cause collisions, other acc idents and
serious pe rsonal in jury.
- Never let the comfort and convenience
that adaptive cruise control and braking gua rd offer d istract you from the need to
be alert to traffic condit ions and the
need to rema in in fu ll control of your ve­
h icle at a ll times,
- Always remember that the adaptive
cruise control and braking guard have
limits -they will not s low the vehicle
down or maintain the set distance when
you drive towards an obstacle or some­
thing on or near the road that is not
mov ing, such as vehicles stopped in a
traffic jam, a stalled o r disabled vehicle.

vehicles or obstacles that are not moving
can trigger a collision warning and if con­
firmed by the video camera, an acute col­ lis ion warn ing.
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condit ion and/or in bad weather
(such as ice, fog, gravel, heavy rain and
hydroplan ing). Using the system under
these cond itions cou ld result in a co lli ­
sion .
- Switch adaptive c ruise control off tempo­
rar ily when driv ing in turning lanes, on
expressway exits or in construction
zones . This prevents the vehicle from ac­
celerating to the set speed when in these
situations .
- The adapt ive cru ise control system w ill
not brake by itse lf if you put your foot on
the accelerator pedal. Doing so can over­ ride the speed and distance regulation .
- When approaching stationary objects such as stopped traffic, adaptive cruise
control will not respond and braking
guard w ill have limited function.
- The adapt ive cruise control system and
braking guard do not react to people, an­
ima ls, objects crossing the road o r on­
coming objects .
- The function of the radar sensors can be
affected by reflective objects such as
guard ra ils, the entra nce to a tunnel,
he avy rain or i ce.
- Never follow a veh icle so closely that you
cannot stop your vehicle safe ly. The
adaptive cruise cont ro l c anno t slow or
brake the veh icle safely when you follow
another vehicle too closely. Always re­
member that the automatic braking
funct ion cannot bring the veh icle to a
sudden or emergency stop under these
condit ions .
- To prevent unintended operation, always
switch ACC off when it is not be ing used. (D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. That cou ld affect the adaptive
cruise control system and brak ing guard .

Audi adaptive cruise control
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 92 Detection range
What can adaptive cruise control do?
The adaptive cruise control system uses video,
radar and ultrasou nd. Moving vehicles ahead
can be recognized up to about 650 feet (200 m) away.
On open roads w ith no traffic, adaptive cruise
control works like a regular cruise control sys­
tem. The stored speed is maintained. When
approaching a moving vehicle detected up
ahead, the adaptive cruise control system au­
tomatically s lows down to match that vehi­
cle's speed and then maintains the distance
that the driver previous ly stored. As soon as
the system does not detect a vehicle up
ahead, adaptive cruise control accelerates
back up to the stored speed.
In stop-and-go traffic, adapt ive cru ise control
can brake until the vehicle stops and acceler­
ate again under certain conditions and if this
is possible within the system's limits and ca­
pabilities¢
page 90. Adaptive cru ise control
will not make an emergency stop .
Which functions can be controlled?
When you switch adaptive cruise contro l on,
you can set the current speed as the "control speed" ¢
page 88, Switching on and off.
When driving, you can stop cruise control
¢
