This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current veh icle-
to-vehicle following distance, and operates to maintain a suita ble fol-
lowing distance from the vehicle ahead. The desired vehicle-to- vehi-
cle distance can also be set by operating the vehicle-to-vehicl e
distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distance may
become shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration crui sing and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle s peed is
necessary, the system applies the brakes (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate su ffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pressing the
“+ RES” switch or depressing the accelerator pedal (start-off o peration) will
resume follow-up cruising. If the start-off operation is not pe rformed, sys-
tem control continues to keep your vehicle stopped.

After the vehicle ahead of you
starts off, press the “+ RES”
switch.
Your vehicle will also resume fol-
low-up cruising if the accelerator
pedal is depressed after the vehi-
cle ahead of you starts off.
Pressing the cancel switch can-
cels the speed control.
The speed control is also canceled
when the brake pedal is
depressed.
(When the vehicle has been
stopped by system control,
depressing the brake pedal does
not cancel the setting.)
Pressing the “+ RES” switch resumes the cruise control and returns
vehicle speed to the set speed.

■Dynamic radar cruise control wi th full-speed range can be set when
● The shift lever is in D.
● The desired set speed can be set when the vehicle speed is approximately
20 mph (30 km/h) or more.
(However, when the vehicle speed is set while driving at below approxi-
mately 20 mph [30 km/h], the set speed will be set to approximately 20 mph
[30 km/h].)
■ Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After acceler-
ating, the set speed resumes. However, during vehicle-to-vehicl e distance
control mode, the vehicle speed may decrease below the set spee d in order
to maintain the distance to the preceding vehicle.
■ When the vehicle stops while follow-up cruising
●Pressing the “+ RES” switch while the vehicle ahead stops will resume fol-
low-up cruising if the vehicle ahead starts off within approxim ately 3 sec-
onds after the switch is pressed.
● If the vehicle ahead starts off within 3 seconds after your vehicle stops, fol-
low-up cruising will be resumed.
■ Automatic cancelation of vehicle-to-vehicle distance control mo de
Vehicle-to-vehicle distance control mode is automatically cance led in the fol-
lowing situations.
● VSC is activated.
● TRAC is activated for a period of time.
● When the VSC or TRAC system is turned off.
● The sensor cannot detect correctly because it is covered in some way.
● When the brake control or output restriction control of a driving support sys-
tem operates. (For example: Pre -Collision System, Drive-Start Control)
● 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 ca nceled for any
reasons other than the above, there may be a malfunction in the system.

• The Intelligent Clearance Sonar system is disabled.
• Approximately 2 seconds elapse after the vehicle is stopped by brake
control.
• The brake pedal is depressed after the vehicle is stopped by b rake con-
trol.
• The object is no longer 6 to 13 ft. (2 to 4 m) away in the traveling direction of the vehicle.
■ Detection range of the Intellig ent Clearance Sonar function
The detection range of the Intelligent Clearance Sonar function differs from
the detection range of the intuitive parking assist. ( P. 298)
Therefore, even if the intuitive parking assist detects an obje ct and provides a
warning, the Intelligent Clearance Sonar function may not start operating.
■ If the Intelligent Clearance Sonar function has operated
If the vehicle is stopped due to operation of the Intelligent C learance Sonar
function, the Intelligent Clearance Sonar system will be disabl ed and the ICS
