Dynamic radar cruise control can also be set when the shift lever is in the S posi-
tion and range 4, 5 or 6 has been selected.
●Vehicle speed is above approximately 30 mph (50 km/h).

tem off by pressing the “ON-OFF” button, and turn it on again.
■Accelerating
The vehicle can be accelerated normally. However, during vehicle-to-vehicle dis-
tance 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 follow-
ing situations:
●Actual vehicle speed falls below approximately 25 mph (40 km/h).
●VSC is activated.
●The sensor cannot operate correctly because it is covered in some way.
●The windshield wipers are operating at high speed.
●The driving mode is set to second start mode.
●Bad weather causes the detection function to become extremely unstable.
●Multi-terrain mode is selected other than OFF.
●The center differential lock/unlock is not completed within 5 seconds while the
dynamic radar cruise control system is on.
If vehicle-to-vehicle distance control driving is automatically canceled for any other
reason, there may be a malfunction in the system. Contact your Lexus dealer.
