■ Dynamic radar cruise control with full-speed range can be set when
● The shift lever is in D.
● Vehicle speed is above approximately 30 mph (50 km/h).
■ Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After accelerating, the
set speed resumes. However, during vehicle-to-vehicle distance control mode, the vehi-
cle speed may decrease below the set speed in order to maintain the distance to the pre-
ceding vehicle.
■ Automatic cancelation of vehicle-to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the following situ-
ations:
● VSC is activated.
● TRAC is activated for a period of time.
● When the VSC or TRAC system is turned off by pressing the VSC OFF switch.
● The sensor cannot detect properly because it is obstructed in some way.
● Brake automatically operated for long periods of time, such as traffic jams, etc.
● The parking brake is operated.
● The vehicle is stopped by system control on a steep incline.
● Pre-collision braking is activated.
● The following are detected when the vehicle has been stopped by system control:
• The driver is not wearing a seat belt.
• The driver’s door is opened.
• The back door or hood is opened.
When vehicle-to-vehicle distance control mode is automatically canceled in the follow-
ing situations, “Radar Cruise Control Unavailable” will be displayed on the multi-infor-
mation display:
● Actual vehicle speed falls below approximately 25 mph (40 km/h) when there are no
vehicles ahead.
● The preceding vehicle leaves the lane when your vehicle is following at a vehicle speed
below 25 mph (40 km/h). Otherwise, the sensor cannot properly detect the vehicle.
● 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).
If vehicle-to-vehicle distance control mode is automatically canceled for any other rea-
son, there may be a malfunction in the system. Contact your Lexus dealer.
