Without accelerator pedal operation by the driver, in vehicle-to-vehicle distance
control mode, the vehicle automatically accelerates and decelerates in accor-
dance to the changes in speed of the preceding vehicle. In constant speed con-
trol mode, the vehicle runs at a fixed speed.
Use the dynamic radar cruise control on freeways and highways.
●Vehicle-to-vehicle distance control mode ( P. 299)

This mode employs a radar sensor to detect the presence of vehicles up to
approximately 120 m (400 ft.) ahead, determines the current vehicle-to-vehicle
following distance, and operates to maintain a suitable following distance from
the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on long downhill slopes.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-vehicle dis- tance can also be set by operating the vehicle-to-vehicle distance control.
Example of deceleration cruising
When a preceding vehicle driving slower than the set speed appears
When a vehicle is detected running ahead of you, the system automatically deceler- ates your vehicle. When a greater reductio n in vehicle speed is necessary, the system applies the brakes (the stop lights will come on at this time). A warning tone warns you
when the system cannot decelerate sufficiently to prevent your vehicle from closing in on the vehicle ahead.
Example of follow-up cruising
When following a preceding vehicle driving slower than the set speed
The system continues follow-up cruising wh ile adjusting for changes in the speed of
the vehicle ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Example of acceleration
When there are no longer any preceding vehicles driving slower than the set
speed
The system accelerates until the set speed is reached. The system then returns to con- stant speed cruising.
