Introduction
Applies to vehicles: with Audi adaptive cruise control
The adaptive cruise contro l system assists the
driver by regulating vehicle speed and helping to
maintain a set distance to the veh icle 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-

Adaptive cruise control and braking guard have
technical limitations that you must know, so
please read this section carefully, understand
how the system works and use them properly at
all times.

modifications made in the front area .
The function of the adaptive cruise control sys-
tem and braking guard is limited under some
conditions:
- Objects can only be detected when they are
within sensor range
c::> p age 86, fig. 91.
- The system has a limited ability to detect ob-
jects that are a short distance ahead, off to the
side of you r vehicle or moving into your lane .
- Some kinds of vehicles are hard to detect; for
example 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

A
WARNING
Always pay attention to traffic when adap t ive
cruise control is switched on and braking
guard is active. As the driver, you are still re-
sponsible for starting and for maintaining
speed and distance to other objects. Braking
guard is used to assist you. The driver must
always take act ion to avoid a collision . The
driver is always respons ible for braking at the
correct time.
- Improper use of adaptive cruise control can
cause collisions , other accidents and ser ious
personal injury.
- Never let the comfort and convenience that
adapt ive cru ise control and braking guard
offe r dist ract you from the need to be alert
to traffic conditions and the need to remain
in fu ll contro l of your ve hicle at all times,
- Always remember that the adaptive cruise
control and braking gu ard have limits - they
will no t slow the vehicle down or maintain
the set distance when you drive towards an
obstacle or something on or near the road
that is not moving, s uch as vehicles stopped
in a traff ic jam, a stalled or disab led vehicle.
If registered by the radar sensors, vehicles
or obstacles that are not moving can trigger
a collision warning and if confirmed by the
video camera, an acute collision warning.
