The distance at which the adaptive cruise con-
trol follows a vehicle in front is determined by
time interva ls. A time interval to a vehicle in
front is estab lished and maintained. This pro-
duces a speed-dependent interval. The higher
the speed, the greater the safety interva l in
feet (meters)

For example, if the interval DI STANCE 3 is
set, a vehicle in front is fo ll owed at a
time in-
terval
of 1.8 seconds.
For a speed of
50 mph (80 km/ h) this wo uld
be equivalent to a distance of
131 feet
(4 0 meter s) to the vehicle in front.
The distances given here are nom inal values.
The vehicle speed may exceed or fall shor t of
these target speeds, depending on the driving
situation and the driving style of the vehicle
