In addition to the norma l functions of a tradi­
tional hand brake, the electromechanica l
parking brake provides various convenience
and safety functions.
When start ing f rom re st
- T he integ ral starting assist helps you when
driving by automatically releasing the park ­
ing brake ¢
page 98, Starting from rest.
-When starting on inclines, the starting as­
sist prevents the vehicle from unintentional­
l y rolling back. The braking force of the
parking brake is not released until sufficient
driv ing force has been built up at the
wheels .

react when you drive towards an obstacle
or something else on or near the road
t h at is not moving, such as vehicles stop­
ped in a traffic jam, a stalled or disabled
vehicle .
- Always remember that the adaptive
cruise control cannot detect a vehicle
that is driving towards you in your traffic lane and that it cannot detect narrow ve­
hicles such as motorcycles and bicycles.
(D Tips
- Fo r safety reasons, the stored speed is
deleted when the ignition is turned off .
- The Electronic Stabilization Program
(ESP) and the Anti-Slip Regulation (ASR)
cannot be deactivated when the adaptive
cruise control is switched on. If the ESP
and the Anti-Slip Regulation (ASR) has been deactivated and you then switch on
the adaptive cruise control, the ESP func­
tion will also be activated automatically.
- Damage caused by accidents (e.g. if the
vehicle is damaged when parking) can af­
fect the radar sensor settings. This can
cause the system to malfunction or
switch off complete ly.
- The radar sensor cover is heated. In win­
ter cond itions, you should still check be­
fore driving to make sure it is free of ice
and snow. If necessary, clean the area
near the radar sensor carefully

Adaptive cruise control 103
How does adaptive cruise control work?
App lies to veh icles: w ith adaptive cru ise control
Vehicles traveling ahead are detected with
the aid of a radar sensor.
Fig. 111 Radar sensor measu re m ent range
A radar sensor is built into the front of the ve­
hicle
9 fig. 111, which is subject to certain
system limits~
page 112. Stationary objects
are not taken into consideration. The system
is intended to measure the distance to reflec­
tive surfaces. The system responds after the
distance measurement has taken place. If a
measurement is not possible, the system does
not respond .
Open road
When the road is clear, the adaptive cruise
control works like cruise control. It maintains
a constant target speed specified by the driv­
er.
Driving in traffic
If a vehicle driving ahead is detected, the
adaptive c ruise control decelerates (within the

Park assist
Parking system
Applies to vehicles: with parking system
Different park assist systems may be used for
parking or maneuvering, depending on the
vehicle's features.
Parking system (rear)*:
For the parking system (rear), the acoustic
park assist system is installed in the rear of
the vehicle
¢ page 133.
The rear parking assist system uses ultrasonic
sensors to determine the distance of the vehi­
cle from a detected obstacle. There are a total
of four sensors located on the rear bumper
(two in the middle and two on the sides) .
Parking system (rear, with rear view
camera)*:
For the parking system (rear, with rear view
camera),
the rear acoustic park assist system
is integrated in the rear of the vehicle and the
rear view camera is integrated in the rear lid
¢page 136.
The parking system (rear , with rear view cam­
era)
uses ultrasonic sensors to determine the
distance of the vehicle from a detected obsta­
cle . There are a total of four sensors located
on the rear bumper (two in the m iddle and
two on the sides).
Parking system (rear)
Rear acoustic park assist
App lies to vehicles: with parking system (rear)
The rear acoustic park assist warns you of ob­
stacles or objects behind your car.
Description
The rear acoust ic parking assist system deter­
mines the distance of the vehicle from an ob­
stacle using ultrasonic sensors. There are 4
sensors in the rear bumper.
The range at which the sensors start to meas­
ure is
about :
Park assist 133
To the side 2 ft (0.60 m)
Center rear 5.2 ft (1.60 m)
Activation
Acoustic parking assist is activated automati­
ca lly when
reverse gear is engaged. A brief
tone confirms that the system is activated.
Warning tones
Distance warning is given by warning tones
which are generated by the rear signal genera­
tor. The vo lume and the pitch of the warning
tones can be adjusted in the MMI*
¢page 134.
Reversing
Distance warning when reversing starts when
an obstacle is detected in the range of the
parking assist system . As the distance de­
creases, the time interval between the aud ible
tones becomes shorter.
When the distance is less than 1 ft (0.30 m),
the tone becomes continuous. At this point
you should stop backing up.
Please note that low objects already signalled
by a warning can disappear from the system's
detection range and will not continue to be
signalled.
If the distance to an obstacle remains the
same, the volume of the distance warning is
gradually reduced after about 4 seconds. Ap ­
proaching another obstacle will result in the
distance warning sounding at the normal vol­
ume again.
Malfunctions in the system
If a warning tone is audible for about five sec­
onds when you turn on the ignition, there is a
malfunction in the system. Have the problem
corrected by your authorized Audi dealer.
Keep the sensors in the rear bumper clean and
free from ice so that the acoustic park assist system can function properly. .,..
