The shift lever is in the D or range “4”, “5”, or “6” or higher of S has been

Accelerating after setting the vehicle speed
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 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 (when the wiper switch is set
to the high speed wiper operation position).
●

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.
