Switching modes
■
The mode cannot be switched to constant speed control mode if vehicle-to-

mode. Turn the system off by pressing the "ON-OFF" button, and turn it on

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.

■
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.
