tiona l hand brake, the electromec hanical
parking brake provides various convenience
and safety funct ions .

-The integral start ing ass ist helps you when
driving by automatically releasi ng the park­
ing brake
¢ page 80, Starting from rest.
-When starting on inclines, the starting as­
sist prevents 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 bui lt up at the
wheels.

92 Audi adaptive cruise control and braking guard
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 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 vehicle up ahead,
adaptive cruise control can brake and then ac ­
celerate your vehicle. This he lps to make driv­
ing more comfortable on long highway
stretches.
The braking guard system can warn you about
an impending collision and initiate braking
maneuvers
c:::> page 98.
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.
General information
General information
Applies to vehicles: with Audi adaptive cruise co ntrol
Fig. 103 Front of the vehicle: Position of radar senso r
The area that contains the radar sensor
c:::> fig. 103 must never be cove red by stickers
or other objects or obstructed with dirt, in­
sects, snow or i ce that will interfere with the
adaptive cruise control system and braking
guard. For information on cleaning, refer to
c:::> page 193. The same applies for any modifi­
cations made in the front area . T
he function of the adaptive cruise cont rol
system and braking guard is limited under
some condit ions:
- Objects can only be detected when they are
within sensor range
c:::>page 94, fig . 106.
-The system has a limited ability to detect
objects that are a short d istance ahead, off
to the side of your vehicle or moving into
your lane.
- Some kinds of vehicles are hard to detect;
for examp le motorcycles, vehicles 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 93.
- Stat ionary objects c:::> page 93 .
A WARNING
-
Always pay attention to traffic when adap-
tive cruise contro l is switched on and brak­
ing guard is active. As the driver, you are
still respons ible for starting and for main­
tain ing speed and distance to other ob­
jects. Braking guard is used to assist you.
The driver must always take action to avoid
a col lision. The driver is always responsible
for braking at the correct time.
- Im proper use of adaptive cruise con trol
can cause collisions, other accidents and
serio us personal injury.
- Never let the comfor t and convenience
that adaptive cruise control and braking
guard offer distract you from the need to
be alert to traffic conditions and the
need to remain in full control of your ve­
h icle at a ll times,
- Always remember that the adaptive
cru ise contro l and brak ing guard have
lim its -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 or disabled vehicle.
If registered by the radar sensor, vehicles
or obsta cles that are not moving can
trigger a co llision warning and if
