104 Adaptive cruise control
When the system is turned off temporari-
ly, the speed stored at the time is retained.
How is the distance (time interval) set?
App lies to vehicles : with adaptive cruise cont rol
Distance con be set in four stages.

The distance at wh ich the adaptive cruise con-
trol follows a vehicle in front is determined by
time interva ls . A time inte rval 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 interval in
yards (meters)

The distances provided are spec ified values.
These distances may exceed or fa ll short of
these target distances, depending on the driv-
ing situation and the driving style of the vehi-
cle ahead.
Distance 1 ,;;:::::,_,;;:::::, _ _ _
This setting is ideal for brisk driving in bump-
er-to -bumper traffic. The distance is one sec-
ond. This is the equiva lent of, for instance,
- a distance of 36 feet (11 meters) at a speed
of 25 mph (40 km/h)
- a distance of 72 feet (22 meters) at a speed
of 50 mph (80 km/h)
- a distance of 108 feet (33 meters) at a
speed of 75 mph (120 km/h)
Di sta nee 2 ,;;:::::, __ ,;;:::::, __
This setting is idea l for "keep ing pace" com-
fortably in bumper-to-bumper t raff ic. The dis-
tance is 1.3 seconds. This is the equiva lent of,
for instance,
- a distance of 46 feet (14 meters) at a speed
of 25 mph (40 km/h)
- a distance of 95 feet (29 meters) at a speed
of 50 mph (80 km/h)
- a distance of 144 feet (44 meters) at a
speed of 75 mph (120 km/h)
Di sta n ce 3 ,;;:::::, ___ ,;;:::::, _
This setting is ideal for "keep ing pace" in
bumper-to-bumper traff ic and is the equ iva-
lent of the generally recommended distance
that is "half of the speedometer speed". The
distance is 1.8 seconds. This is the equivalent
of, for instance,
- a distance of 66 feet (20 meters) at a speed
of 25 mph (40 km/h)
- a distance of 131 feet (40 meters) at a
speed of 50 mph (80 km/h)
- a distance of 197 feet (60 meters) at a
speed of 75 mph (120 km/h)
Di sta n ce 4 ,;;:::::, ____ ,;;:::::,
This setting is idea l for secondary road traffic.
The distance is 2.3 seconds . This is the equiva-
lent of, for instance,
- a distance of 82 feet (25 meters) at a speed
of 25 mph (40 km/h)
- a distance of 167 feet (51 meters) at a
speed of 50 mph (80 km/h)
- a distance of 249 feet (76 mete rs) at a
speed of 75 mph (120 km/h)
