cal parking b rake. The parking b rake is designed
to prevent the veh icle from rolling unintentional ­
ly and replaces the hand brake.
I n addition to t he normal func tions of a tradi tion­
al hand brake, the e lectromechanica l parking
b rake provides var ious convenience and safety
functions.

Engine does not switch off
Before and during each stop phase, the system
checks if certain conditions have been met . For
examp le, the engine will not switch off in the fol­
lowing situations:
- The engine has not reached the minimum re­
quired temperature for Start-Stop mode.
- The interior temperature selected by the A/C
system has not been reached.
- The outside temperature is extremely high/low.
- The windshield is being defrosted@.
- The parking system* is be switched on .
- The battery charge level is too low .
- The steering wheel is turned at a sharp angle or
is moving .
- After engaging the reverse gear.
- On sharp inclines.

play.
Engine automatically restarts
The standard Start-Stop mode will be canceled
during a stop phase in the following situations .
The engine restarts without any action by the driver.
Driving
- The vehicle rolls, for examp le while on a s lope.
- The interior temperature varies from the tem-
perature selected in the A/C system.
- The windshield is being defrosted@.
- The brake pedal is pressed severa l times in a
row.
- The battery charge level becomes too low.
- High power consumption.
The engine can turn off again when the condi­ tions for Start-Stop mode are met.
Ignition is switched off automatically
To prevent the battery from draining, the igni­
tion
will switch off automatically under the fol­
lowing conditions:
- The vehicle has already been driven.
- The Start-Stop-System has stopped the engine.
- The driver's door is opened .
- The driver's safety belt is removed.
- The brake pedal is not pressed down.
- The vehicle is stationary.

and the distance between your vehicle and
other vehicles.
- For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads and when road cond itions are
poor (such as ice, fog, gravel, heavy rain and
hydroplaning), because this increases the
risk of an accident.
- Switch the cruise control off temporarily
when dr iv ing in turning lanes, h ighway ex its
or in construction zones.
- Please note that unconsciously "resting" your foot on the accele rator pedal p revents
the cruise control from braki ng. This is d ue
to the contro l system being over ridden by
the dr iver's acceler ation.

Audi adaptive cruise
control and braking
guard
Introduction
App lies to vehicles: with Audi adaptive cruise control
The adaptive cruise control system assists the
driver by regu lating vehi cle speed and helping to
maintain a set distance to the vehicle ahead,
within the limits of the system.
If the system de­
tects a moving vehicle up ahead, adaptive cruise
control can brake and then accelerate your vehi­
cle. This helps to make driving 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 maneu­
vers¢
page 91.
Adaptive cruise control and braking guard have
technica l limitations that you m ust know, so
p lease read this section carefu lly, understand
how the system works and use them properly at
all times.
General information
General information
Applies to vehicles: with Audi adaptive cruise control
Fig. 89 Front of th e veh icle: sensors and video camera
The areas that contain the radar and ultrason ic
sensors and the video camera ¢
fig. 89 must nev­
e r be covered by stickers or other objects or ob­
structed with dirt, insects, snow or ice that will
interfere with the adaptive cruise contro l system
and braking guard . For information on cleaning, refer to
¢
page 205. The same applies for any
modif ications made in the front area.
T he function of the adaptive cru ise contro l sys­
tem and braking guard is limited unde r some
conditions:
- Objects can only be de tected when they are
w ith in sensor range
¢page 87, fig. 92.
- The system has a limited ability to detect ob­
jec ts that are a shor t distance ahead, off to the
side of yo ur vehicle or mov ing into your lane .
- Some kinds of veh icles are hard to detect; for
examp le motorcycles, vehicles with high
ground clear ance or overhanging loads may be
detected when it is too late o r they may not be
detected at all.
-When driving through curves

_& WARNING
Always pay a ttent ion to traffic when adap tive
cr uise control is switched on and braking
guard is active. As the driver, you are sti ll re­
sponsib le for starting and for maintaining
speed and distance to other objects. Braking
guard is used to assist you. The driver must
a lways take action to avo id a col lision . The
d river is always responsible for brak ing at the
correct t ime.
- Improper use of adaptive cruise control can cause collisions, other accidents and serious
pe rsonal inj ury.
- Never let the comfort and conve nience that
adapt ive cr uise control and b rak ing guard
offer distrac t you from the need to be alert
to traffic condit io ns and the need to remain
in full control of your veh icle at all times,
- Always remember tha t the adaptive cruise
con trol and bra king guard have limits -they
will no t slow the vehicle down or maintain
the set distance when you dr ive towards an
obstacle or something on or near the road
that is not moving, s uch as vehicles stopped
in a traffic jam, a stalled or disabled vehicle.
If registered by the radar sensors, vehicles
or obstacles that a re not moving can trigger
a collision wa rning and if confirmed by the
video came ra, an acute collision warning.

Audi adapt ive cru ise control and brak ing gu ard
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydrop lan­
ing). Using the system under these condi­
t ions could resu lt in a col lision.
- Switch adaptive cruise control off tempora­
rily when driving in turn ing lanes, on ex­
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the set speed when in these situat ions.
- The adapt ive cr uise control sys tem wi ll not
brake by itself if yo u put you r foot on the ac­
celerator pedal. Doing so can ove rride the
speed and distance regulation.
- When approach ing stationary objects such
as stopped traffic, adaptive cruise control
will not respond and braking g uard will have
limited function.
- The adapt ive cr uise control system and brak­
ing guard do not react to people, animals,
objects cross ing the road or oncoming ob­
jects .
- The function of the radar sensors can be af­
fected by reflective objects such as guard
rails, 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 adap­
t ive cru ise control cannot s low or brake the
vehicle safely when you fo llow another veh i­
cl e too close ly. Always remembe r that the
automa tic brak ing funct ion c annot bring the
vehicle to a sud den or emergency stop un­
der these conditions.
- To prevent unin tended operation, always
switch ACC off when it is not be ing use d.
(D Note
The sensors can be displac ed by impacts or
damage to the bum per, whee l hou sing and
unde rbody. That could affe ct the adap tive
cruise contro l system and braking guard . Have
your authorized A udi dealer or authorized
Audi Service Facility c heck their function.

The adaptive cruise contro l system only reacts to
ob jects that are moving or that the system has
already detected as moving. For example, it can
react when a vehicle that has already been de­
t ec ted @ turns or changes lanes, but adapt ive
cruise control does not react to a stationary vehi ­
cle @.
