Driving in vehicle-to-vehicle distance control mode
This mode employs a radar to detect the presence of vehicles up to
approximately 100 m (328 ft.) ahead, determines the current vehicle-
to-vehicle following distance, and operates to maintain a suitable fol-
lowing distance from the vehicle ahead. The desired vehicle-to-vehi-
cle distance can also be set by operating the vehicle-to-vehicle
distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distance may
become shorter.
