What can adaptive cruise control do?
The adaptive cruise control system uses video, ra-
dar and ultrasound . Moving vehicles ahead can
be recognized up to about 650 feet (200 m)
away.
On open roads with no traffic, adaptive cruise
control works like a regular cruise control sys-
tem. The stored speed is mainta ined. When ap-
proaching a moving vehicle detected up ahead,
the adaptive cruise cont rol system automatically
slows down to match that vehicle's speed and
then maintains the distance that the driver previ-
ously stored. As soon as the system does not de-
tect a vehicle up ahead, adaptive cruise control
accelerates back up to the stored speed.
In stop-and-go traffic, adaptive cruise control can
brake until the vehicle stops and accelerate again
under certain conditions and if this is possible
within the system's limits and capabilities
¢ page 88. Adaptive cruise control will not
make an emergency stop .
Which functions can be controlled?
When you switch adaptive cruise control on, you
can set the current speed as the "control speed"
¢ page 86, Switching on and off.
