Audi adaptive cruise control and braking guard
Audi adaptive cruise
control and braking
guard
Introduction
Applies to vehicles: with Audi adaptive cruise contro l
The adaptive cruise control 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
on long highway stretches.
The braking guard system can warn you about an
impending collision and initiate braking maneu­
vers

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

The function of the adaptive cruise control sys ­
tem and braking guard is limited under some
condit ions:
- Objects can only be detected when they are
within sensor range
<:!) page 100, fig . 115.
-The system has a limited ability to detect ob­
jects that are a short distance ahead, off to the
side of your vehicle or moving into your lane.
- Some k inds of veh icles 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

& WARNING
-Always pay attention to traffic when adaptive
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 responsible for braking at the
cor rect time.
- Improper use of adaptive cruise contro l can
cause collisions, other accidents and serious
personal injury.
- Never let the comfort and convenience that
adapt ive cr uise control and braking guard
offe r distract you from the need to be alert
to traffic conditions and the need to remain
in full control of your ve hicle at all times,
- Always remember that the adaptive cruise
control and braking guard have limits -they
will not 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, such as vehicles stopped
in a traff ic jam, a stalled or disabled veh icle.
If registered by the radar sensor, veh icles o r
obstacles that are not moving can trigger a
coll ision warning and if confirmed by the
video camera, an acute collision warning. ..,
