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).

LASER BEAM AIMING ADJUSTMENT
LASER BEAM AIMING ADJUSTMENT
OutlineINFOID:0000000001328812
Adjust the laser beam aiming every time the ICC sensor is removed or installed.
CAUTION:
Adjust laser beam aiming at a horizontal place as
far as 12 m (39 ft) forward the vehicle can be seen.
Adjust laser beam aiming 5 seconds after starting engine.
Never view ICC sensor integrated un it body window directly during laser beam aiming adjustment.
Follow the CONSULT-III when adju sting the laser beam aiming (laser beam aiming adjustment can-
not be operated without CONSULT-III).
Never ride on vehicle during l aser beam aiming adjustment.
Idle and turn headlamps OFF duri ng laser beam aiming adjustment.
PreparationINFOID:0000000001328813
Adjust the tire pressure to the specified value.
See that there is no load in the vehicle.
Coolant, engine oil filled up to correct level and full fuel tank.
Shift the gear into “P” position and release the parking brake.
Clean the ICC sensor with a soft cloth.
Outline of Adjustment ProcedureINFOID:0000000001328814
1. Set up the ICC target board [KV99110100 (J-45718)].
2. Adjust the sensor following the procedure on CONSUL T-III. (Turn manually the screw for up-down position
adjustment. ICC sensor automatically adjust the right-left position.)
Setting the ICC Target BoardINFOID:0000000001328815
Accurate ICC target board setting is required for the laser beam aiming adjustment.
CAUTION:
ICC system does not function normally if laser beam aiming is not accurate.
ADJUSTING HEIGHT OF THE TARGET
1. Attach a triangle scale at the center.
