Electromechanical
parking brake
Operating
The electromechanical parking brake replaces
the hand brake.
Fig. 82 Ce nter conso le: Park ing brake
~ Pull the switch@~ fig. 82 to set the park­
ing brake . The . (USA models)/ . (Cana­
da models) indicator lights in the button
and in the instrument cluster display turn
on .
~ To release the parking brake, press the brake
or acce le rator pedal while the ignit ion is
switched on and press the button @at the
same time. The. (USA models)
I. (Can­
ada models) indicator lights in the button
and in the display turn off .
Your veh icle is eq uipped with an electrome­
chanical parking brake. The parking brake is
designed to prevent the vehicle from rolling unintentionally and replaces the hand brake.
I n addition to the normal functions of a tradi­
tional hand brake, the electromechanical parking brake provides various convenience
and safety functions.
When starting from a stop
- T he integral hill start assist helps you when
dr iving by automatically releasing the park­
ing brake ~
page 83, Starting from a
stop .
-When starting on inclines, the hill start as­
sist prevents the vehicle from unintentional­
l y rolling back. The braking force of the
parking brake is not released until sufficient driving force has been built up at the
wheels.
Emergency brake function
An emergency braking functions ensu res that
the vehicle can be slowed down even if the
normal brakes fail~ page 84, Emergency
braking function.
_.&. WARNING
- Do not press the accelerator pedal inad­
vertently when the vehicle is stationary
and the engine is running and a gear is
selected. Otherwise the vehicle will start
to move immediately and could result in
a crash .
- If the power supply fails, the released
parking brake can no longer engage . In
this case, park the vehicle on leve l
g round and secure it by placing these­
lecto r lever in the P position. See an au­
thorized Audi dealer or authorized Audi
Service Facility for assistance.
(D Note
If the. or. (USA models) I. (Cana­
da models) indicator light in the instru­
ment cluster blinks, there is a malfunction
i n the brake system. Refer to the detai led
description of the indicator lights
~page 18.
- If the . (USA models) I. (Cana-
da models) or
Ill indicator light turns
on, there is a malfunction in the parking
brake
c> page 19.
(D Tips
- If the electromechanica l parking brake is
set while the ignition is switched off, the
¢@'A indicator light in the button and in
the instrument cluster dis-
play . (USA models) /. (Cana-
da models) will turn off after a certain
amount of time.
- If driver's door is opened while the igni­
tion is switched on, the park ing brake
sets automatically. This prevents unin­
tended rolling of the vehicle.

88 Audi adaptive cruise control
- When approaching stationary objects
such as stopped traff ic, adaptive cruise
control will not respond and pre sense
front will have limited function.
- The adaptive cruise control system and
pre sense front do not react to people,
animals, objects cross ing the road or on­
coming objects.
- The function of the radar sensors can be
affected by reflective objects such as
guard rai ls, the entrance to a tunnel,
heavy rain or ice.
- Never follow a veh icle so closely that you
cannot stop your vehicle safe ly. 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 ca nnot 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 sensor can be disp laced by impacts o r
damage to the bumper, whee l housing and
underbody . The adaptive cruise contro l
and pre sense front may become impaired
as a result . Have an authorized Audi dealer
or author ized Audi Service Facility check
their function.
In curves
Applies to vehicles: with Audi adaptive cruise control and
Audi pre sense fro nt
Fig. 85 Examp le: driv ing into a curve
When driving into a curve c::> fig. 85 and out of
a curve, the adaptive cruise control may react
to an object in the neighboring lane and apply
the brakes. You can prevent that by pressing
the accelerator pedal briefly .
Stationary objects
Applies to vehicles: with Audi adaptive cruise contro l and
Audi pre sense front
Fig. 86 Example: object chang ing lanes a nd stationary
object
Adaptive crui se control
The adaptive cruis e control system only reacts
to objects that are moving or that the system has a lready detected as moving. For examp le,
if a detected vehicle @tur ns or changes
lanes, the adaptive cruise control will not re­
act to a stopped vehicle @. Press the brake
pedal to slow your vehicle down .
Pre sense front
Pre sense front only reacts to stationary ob­
jects at low speeds.

What can adaptive cruise control do?
The adaptive cruise control system uses rada r
and a video camera. The radar is subject to
designated system limits ¢ page 87.
On open roads w ith no traffic, it functions l ike
a cruise control system . Th e stored speed is
maintained . When approaching an object
ahead and the system detects it, the adaptive
cr uise control system automatically brakes to
match that object's speed and then maintains
the stored distance. As soon as the system
does not detect an object ahead, adaptive
cru ise control accelerates up to the stored
speed .
With in the limits of the system, adaptive
cru ise control can brake in stop-and-go traff ic
until the vehicle is stationary and then begin
driving aga in under certa in conditions
¢ page 91, Driving in stop-and-go traffic.
Which functions can be controlled?
When you switch adaptive cruise control on,
you can set the current speed as the "control speed" ¢ page
89, Switching on/off.
When driving, you can stop cruise control
c::> page 91 or change the speed c::> page 90
at any time .
You can also adjust the following settings:

If adaptive cruise control is not shown in the
instrument cluster disp lay, you can call it up
using the mu ltifunction steering wheel but­
tons
r:!> page 2 7.
Based on the graphics in the disp lay, yo u can
determine if the system is maintaining a dis ­
tance to a vehicle ahead and what that dis­
tance to this vehicle is:
No vehicle -No object ahead was detected .
White vehicle -An object ahead was detected.
Red vehicle -Request for the driver to take ac­
tion
c> page 93 .
Both arrows on the scale© indicate the dis­
tance to the object ahead. No arrow appears
when the vehicle is on an open road and there
is no object ahead.
If an object is detected
ahead, the arrow moves on the scale .
The green zone on the scale indicates the
store distance. For information on changing the d
istance, refer to
i=;, page 92. If the dis­
tance selected is exceeded or not reached, the
arrow moves into the red zone on the scale.
A WARNING
- Using adaptive cru ise control incorrectly
can cause collisions, other accidents and
serious injuries.
- If you press the
~IS-ET~I button when driv­
ing at speeds below 20 mph (30 km/h),
the vehicle accele rates automatically up
to 20 mph (30 km/h), which is the mini­
mum speed that can be set.
(D Tips
-If you switch the ignit ion or the adaptive
cruise control system off, the set speed
is erased for safety reason.
- The Electronic Stabilization Control (ESC)
and Anti-Slip Regulat ion (ASR) both
switch on when the adaptive cruise con­
trol is switched on. ESC and ASR cannot
be switched
off when adaptive cruise
contro l is switched on.
- With the adaptive cruise control activat­
ed the ESC sport mode canno t be activat­
ed.

Driving in stop-and-go traffic
Appl ies to vehicles: w ith Audi adaptive cruise co ntrol
The adaptive cruise control system assists you
in stop-and-go traffic. If an object that is de­
tected ahead stops, your vehicle will brake
and stay at a stop, within the limits of the sys­
tem.
