■ Dynamic radar cruise control with full-speed range can be set when
● The shift lever is in D or range 4 or higher of S has been selected.
● Range 4 or higher of D has been selected by using the paddle shift switch (vehicles with
paddle shift switches).
● Vehicle speed is at or above approximately 50 km/h (30 mph).
However, when a preceding vehicle is detected, the dynamic radar cruise control with
full-speed range can be set even if the vehicle speed is below approximately 50 km/h
(30 mph).
■ 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.
■ When the vehicle stops while follow-up cruising
● Pushing the lever up while the vehicle ahead stops will resume follow-up cruising if the
vehicle ahead starts off within approximately 3 seconds after the lever is pushed up.
● If the vehicle ahead starts off within 3 seconds after your vehicle stops, follow-up cruis-
ing will be resumed.
■ Automatic cancelation of vehicle-to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the following situ-
ations:
● Actual vehicle speed falls below approximately 40 km/h (25 mph) when there are no
vehicles ahead.
● The preceding vehicle leaves the lane when your vehicle is following at a vehicle speed
at or below approximately 40 km/h (25 mph). Otherwise, the sensor can not properly
detect the vehicle. (“CRUISE NOT AVAILABLE No Preceding Vehicles” is displayed
on the multi-information display)
● VSC is activated.
● Active TRC is activated for a period of time.
● When the VSC or Active TRC system is turned off.
● When second start mode is set.
● The sensor cannot detect correctly because it is covered in some way.
● Pre-crash braking is activated.
● The parking brake is operated.
● The vehicle is stopped by system control on a steep incline.
● 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 vehicle has been stopped for about 3 minutes
● The switching operation continues for 5 seconds or more after the center differential
lock switch has been operated.
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.
