■Dynamic radar cruise control can be set when
● The shift position is in “D”.
● Vehicle speed is above approximately 30 mph (50 km/h).
■ Switching modes
The mode cannot be switched to constant speed control mode if vehicle-to-
vehicle distance control mode has been used. The mode also cannot be
switched from constant speed control to vehicle-to-vehicle distance control
mode. Turn the system off by pressing the “ON-OFF” button, and turn it on
again.
■ Accelerating
The vehicle can accelerate normally. After acceleration, 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 vehicle ahead.
■ Automatic cancelation of vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the
following situations:
● Actual vehicle speed falls below approximately 25 mph (40 km/h).
● Enhanced VSC is activated.
● The sensor cannot operate correctly because it is covered in some way.
● The windshield wipers are operating at high speed.
If vehicle-to-vehicle distance control driving is automatically canceled for any
other reason, there may be a malfunction in the system. Contact your Toyota
dealer.
