312 5-4. Using the driving support systems
■ Operating conditions ●The D shift position is selected.
●The desired set speed can be set when the vehicle speed is approximately 20 mph( 30 km / h) or more.
• If the vehicle speed is set while driving at below approximately 20
mph( 30 km / h), the set vehicle speed will be approximately 20 mph( 30 km / h).
• If the vehicle speed is set while driving at a speed that exceeds the system’ s upper limit, the set
vehicle speed will be the system’ s upper limit.
■ Accelerating after setting the vehicle speed
As with normal driving, acceleration can be performed by depressing the
accelerator pedal. After accelerating, the vehicle will return to the set vehicle speed. However, while in
vehicle-to-vehicle distance control mode, the vehicle speed may decrease to below the set vehicle
speed in order to maintain the distance from the preceding vehicle.
■ When the vehicle is stopped by system control during follow-up
cruising
●When the“ RES” switch is pressed
while the vehicle is stopped by system control, if the preceding vehicle starts off within approximately 3 seconds, follow-up cruising will resume.
●If the preceding vehicle starts off within approximately 3 seconds of the vehicle being stopped by system control, follow-up cruising will resume.
■ Automatic cancelation of vehicle-to-vehicle distance control mode
In the following situations, vehicleto-vehicle distance control mode will be canceled automatically:
●When the brake control or output restriction control of a driving support system operates( For example: Pre-Collision System, drive-start control)
●When the parking brake has been operated
●When the driver’ s seat belt is unfastened while driving
●When the Pre-Collision System is disabled
●When the vehicle is stopped by system control on a steep incline
●When any of the following are detected while the vehicle is stopped by system control:
• The driver’ s seat belt is unfastened
• The driver’ s door is opened
• Approximately 3 minutes have elapsed since the vehicle was stopped
The parking brake may be activated automatically.
●Situations in which some or all of the functions of the system cannot operate: �P. 266
■ Dynamic radar cruise control system warning messages and buzzers
For safe use: �P. 259
■ Preceding vehicles that the sensor may not detect correctly
In the following situations, depending on the conditions, if the system
cannot provide sufficient deceleration or acceleration is necessary, operate the brake pedal or accelerator pedal.
As the sensor may not be able to correctly detect these types of vehicles, the approach warning( �P. 313) may not operate.
●When a vehicle cuts in front of your vehicle or changes lanes away from your vehicle extremely slowly or quickly
