■ Dynamic radar cruise control with full-speed range can be set when
● The shift lever is in D.
● Range 4 or higher of D has been selected by using the paddle shift switch.
● Vehicle speed is above approximately 30 mph (50 km/h).
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 at or below 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.
● 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 approximately 25 mph (40 km/h). Otherwise, the sensor can not properly
detect the vehicle.
● 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.
● When snow mode is set.
● The sensor cannot detect correctly because it is covered in some way.
● Pre-collision 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
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.
■ Automatic cancelation of constant speed control mode
Constant speed control mode is automatically canceled in the following situations:
● Actual vehicle speed is more than approximately 10 mph (16 km/h) below the set vehi-
cle speed.
● Actual vehicle speed falls below approximately 25 mph (40 km/h).
● 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.
● Pre-collision braking is activated.
If constant speed control mode is automatically canceled for any other reason, there may
be a malfunction in the system. Contact your Lexus dealer.
