■ Dynamic radar cruise control can be set when
● The shift lever is in the D or range 4 or higher of S has been selected.
● Range 4 or higher has been selected by using the paddle shift.
● Vehicle speed is above approximately 30 mph (50 km/h).
■ 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.
■ 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 (when the wiper switch is set
to the “AUTO” mode or the high speed wiper operation position).
● When snow mode is set.
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.
■ Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following situations:
● Actual vehicle speed is more than approximately 10 mph (16 km/h) below the
set vehicle speed.
At this time, the memorized set speed is not retained.
● Vehicle speed falls below approximately 25 mph (40 km/h).
● VSC is activated.
