Adaptive cruise control
and braking guard
Introduction
Applies to vehicles: with 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 helps to make driv
ing more comfortable both on long highway
stretches and in stop -and-go traffic.
Aud i braking guard can warn you about an im
pending collision with a vehicle up ahead that
is slower or has slowed down and start slow
ing your vehicle down with the brakes
