speed
The vehicle can accelerate by operating the

vehicle ahead stops will resume follow-
up cruising if the vehicle ahead starts off
within approximately 3 seconds after the
switch is pressed.
● If the vehicle ahead starts off within 3 sec-
onds after your vehicle stops, follow-up
cruising will be resumed.
