● Depending on the control mode, this item can be set at the following
speeds.
• Vehicle-to-vehicle distance control mode: Approximately 30 km/h (20
mph) or more
• Constant speed control mode: Approximately 30 km/h (20 mph) or more
■ 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.
■ Shift position selection (vehicles with manual transmission)
Select a shift position according to the vehicle speed. If the engine speed is
too high or too low, control may be automatically canceled.
■ Automatic cancelation of vehicle-to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the fol-
lowing situations.
● Actual vehicle speed falls below approximately 25 km/h (16 mph).
● VSC is activated.
● TRC/A-TRC is activated for a period of time.
● When the VSC, TRC/A-TRC system is turned off.
