Select distance
The distance at which the adaptive cru ise control follows a vehicle in
front is determined by
time intervals . A time interval to a vehicle in
front is estab lished and maintained. This produces a speed-depen-
dent interval. The higher the speed, the greater the safety interval in
yards (meters) ~ & -
The distances provided are specified values. These distances may
exceed or fall short of these target distances, depending on the
driving situation and the driving style of the vehicle ahead.
Distance 1 ~ - ~ ---
This sett ing is ideal for brisk driving in bumper-to-bumper traffic. The
distance is one second. This is the equivalent of, for instance,
• a distance of 36 feet (11 meters) at a speed of 25 mph (40 km/h)

Safety first
• a d istance of 72 feet (22 meters) at a speed of 50 mph (80 km/h)
• a dist anc e of 108 feet (33 meters) at a speed of 75 mph (120
km/h)
Distance 2 ,;::::,-- ~ --
This setting is ideal for "keeping pace" comfortably in bumper-to-
bumper traffic. The distance is 1.3 seconds. This is the equ ivalent of,
for instance,
• a distance of 46 feet (14 meters) at a speed of 25 mph (40 km/h)
• a d ista nce 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 (12 0
km/h)
Distance 3 ~ --- ~ -
This setting is idea l for "keeping pace" in bumper-to-bumper traffic
and is the equivalent of the generally recommended distance that is
"half of the speedometer speed" . The distance is 1.8 seconds. This is
th e equivalent of, fo r instance,
• a d istance 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)
Distance 4 ~ ---- ~
This sett ing is ideal for secondary road traffic. The distance is 2.3
seconds. This is the equivalent 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 meters) at a speed of 75 mph (120
km/h)
You can set the way your vehicle performs in ACC mode when acce ler-
ating and braking in the radio or MM!* ~
page 125. Depending on
the driving program and distance you select , you r vehicle's accelera-
tion and brak ing can range from dynam ic (1) to comfortable (5) . _,.
