●The shift position is in D.
●Vehicle speed is above approximately 50 km/h (30 mph).
However, when a preceding vehicle is detected, the dynamic radar cruise
control with full-speed range can be set even if the vehicle speed is at or
below approximately 50 km/h (30 mph).
■Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After acceler-
ating, the set speed resumes. However, during vehicle-to-vehicle distance
control mode, the vehicle speed may decrease below the set speed in order
to maintain the distance to the preceding vehicle.
■Automatic cancelation of vehicle-to-vehicle distance control mode

lowing situations.
●Actual vehicle speed falls below approximately 40 km/h (25 mph) when
there are no vehicles ahead.
●The preceding vehicle leaves the lane when your vehicle is following at a
vehicle speed below approximately 40 km/h (25 mph). Otherwise, the sen-
sor can not properly detect the vehicle.
