VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE
Set Checking
1. Press the MAIN switch for less than 1.5 seconds.
2. Drive the vehicle between 40 km/h (25 MPH) and 144 km/h (90 MPH).
3. Push the SET/COAST switch.
4. Confirm that the desired speed is set as hand is released from the SET/COAST switch.
NOTE:
 When there is no vehicle ahead, drive at the set speed steadily.
 When there is a vehicle ahead, control to maintain distance from the vehicle ahead, watching its speed.
 The set vehicle speed is displayed on the ICC system indicator in the combination meter.
Check For Increase Of Cruising Speed
1. Set vehicle-to-vehicle distance control mode at desired speed.
2. Check if the set speed increases by 1 km/h (1 MPH) as RESUME/ACCELERATE switch is pushed.
NOTE:
The maximum set speed of the vehicle-to-vehicl e distance control mode is 144 km/h (90 MPH).
Check For Decrease Of Cruising Speed
1. Set vehicle-to-vehicle distance control mode at desired speed.
2. Check if the set speed decreases by 1 km/h (1 MPH) as SET/COAST switch is pushed.
NOTE:
 Vehicle-to-vehicle distance control mode is automatica lly turned off when the driving speed lowers to 32 km/
h (20 MPH) due to the deceleration of the vehicle ahead.
 The minimum set speed of the vehicle-to-vehicle distance control mode is 40 km/h (25 MPH).
Check For Cancellation Of Vehicle-To-Vehicle Distance Control Mode (Normal Driving Condition) In The Following
Cases:
 When the brake pedal is depressed after the system is turned ON.
 When the selector lever is shifted to the “N” (Neutral) position.
 When the MAIN switch is turned OFF.
 When CANCEL switch is operated.
Check For Restoring Speed That Is Set By Vehicle-To-Vehicle Distance Control Mode Before Cancellation
1. Cancel the system by depressing the foot brake. Then, check that the speed before cancellation is
restored when pressing RESUME/ACCELERATE switch with 40 km/h (25 MPH) or above.
2. Cancel the system by shifting the selector lever to “N” position. Then, check if the speed set before the
cancellation is restored when RESU ME/ACCELERATE switch is pushed up.
3. Check if the speed previously set is restored w hen RESUME/ACCELERATE switch is operated with driv-
ing 40 km/h (25 MPH), after canceling vehicle-to-v ehicle distance control mode by operating the CANCEL
switch.
Check For MAIN Switch
1. Start engine. Then, check if the following operations are per- formed correctly.
2. Vehicle-to-vehicle distance control mode is displayed in combi- nation meter illuminates when MAIN switch is pressed “ON” for
less than 1.5 seconds and ready for operation. The illumination
goes off when MAIN switch is turned to OFF.
3. “CRUISE” illumination and ICC system display go off when the ignition switch is turned to OFF while MAIN switch is ON
(“CRUISE” illumination is ON and vehicle-to-vehicle distance
control mode is ready for operation).

2. Check if the set speed increases by 1.6 km/h (1 MPH) as RESUME/ACCELERATE switch is pushed up.
NOTE:
 If the RESUME/ACCELERATE switch is kept pushing up during cruise control driving, the vehicle speed
increases until the switch is released.
 The maximum set speed is 144 km/h (90 MPH).
Check For Decrease Of Cruising Speed
1. Set the conventional (fixed speed) cruise control mode at desired speed.
2. Check if the set speed decreases by 1.6 km/h (1 MPH) as SET/COAST switch is pushed down.
NOTE:
 Conventional (fixed speed) cruise control mode is automatically turned off when the driving speed lowers to 32 km/h (20 MPH).
